How to make a snow blower out of friendship. Homemade snow blower with an engine from the Ural chainsaw. German chainsaw "Stihl"

The winter period, in addition to frost, brings us a large amount of snow. Sometimes its quantity is so large that it is simply not possible to cope with its cleaning with a simple shovel. Therefore, a person creates a technique that can make his life easier and save time for other things.

One such mechanized innovation was snow blowers. But any technique costs a lot of money, so home craftsmen began to think about what to create them with their own hands. They thought about it - and created snow blowers from chainsaws. A homemade snow blower from a chainsaw significantly reduces the time spent on snow removal, and also allows you to thoroughly clean your territory from precipitation.

This article will describe the options for creating snowplows with your own hands. It turns out that you can make your own snowplow from the Druzhba chainsaw, which will significantly save the accumulated funds due to the fact that the scheme for creating a snowplow is very simple, and the details can be found at a flea market or in grandfather's garage.

To solve our problem, there is no need to purchase the most powerful units, a low-power chainsaw will suffice, for example, with a power of five hp or more. With.

An example of a homemade snowplow harvester based on the URAL chainsaw

We will tell you how you can make a homemade snow blower with your own hands from a Ural chainsaw. The layout of this unit is very good. Its design provides for a high-quality transmission that protects the saw from breakage.

And the inertial clutch allows you to protect the inside of the saw from damage by external objects. So, if a foreign body gets inside, the saw immediately turns off, which allows it to be cleaned and to avoid breakage. A do-it-yourself snow blower from a chainsaw does not provide for complex details; when designing it, you do not need to grind complex mechanisms for hours or buy them.

For manufacturing you will need:

chainsaw "Ural", she acts as a donor;
sheet metal 2 mm thick, necessary for the manufacture of blades and blades;
sheet stainless steel 1 mm thick;
a pair of bearings at 48;

arcs and crossbars (20x20), can be taken from the old greenhouse;
consumables: nuts, washers, bolts;
stars and chains from old Soviet motorcycles;
rubber handles for convenience of work with a snow blower.

As you can see from the list above, homemade does not require the purchase of new materials, it is enough to rummage in the garage or go to the nearest flea market.

Snow blower assembly

The design of a homemade snow blower from the Ural chainsaw includes:

gas tank;
engine;
wheelbase;
cardan shaft;
leading star;
bearings.

First of all, you need to take care of a strong mount for the chainsaw motor. To avoid distortions and uneven scooping of snow, the motor must be placed strictly in the center of the device. The subsequent modification of the motor is an addition in the form of a gas tank. For convenience, it is attached to the steering support. This can be done with a bolted connection. You can also take the throttle with a cable from the motorcycle, this will provide unhindered control of the engine throttle.

In order for the snowplow to get its functional abilities, it is necessary to weld the frame. To do this, we do not need to look for complex drawings, because the design is very simple and does not require much effort to assemble.

To create a bucket, you will need pipes with a square section, having dimensions of 20x20x1.7 mm. A frame is assembled from them, which will later be covered with galvanized steel, which will protect the ladle from rusting and decay.

The thickness of the steel here should not be less than five millimeters, otherwise it will be too susceptible to mechanical influences. The sheets are attached to the frame with simple aluminum rivets.

For ease of control, a metal plate should be welded to the bucket structure. It will ensure the smooth movement of the bucket on the snow. The dimensions of such a plate should not exceed 60 centimeters in width, and 4 in length. In this case, the plate can be covered with polyethylene. This will keep the snow from sticking to the plate.

The most important element in the design of the snow blower is its shaft. Its design consists of a pipe with welded screws. When designing a shaft, we need:

steel pipe with a section of ½;
a driven star that needs to be welded to the pipe;
bearings in the amount of two units, which are mounted inside the screw pipe;
rotor wing;
a pair of rotor blades;
screws to create a shaft;
blade wings;
support angles in the amount of two units.

The design of the shaft implies a rotor with welded screws in parallel, looking in different directions. First you need to take a steel pipe with parameters 22x2 mm, and a length of 570 mm. Bearings must be placed at the ends of this pipe. To do this, weld the trunnion to the places where the pipe ends and subsequently put the bearings there. Bearing parameters: sizes 40/16/16, closed design.

Further design provides for the installation of an additional star in the center of the shaft. With its help, torque from the motor will be transmitted to the shaft. These 2 elements will be connected by a chain that can be taken from an old Soviet motorcycle.

The central star in its structure should have 33 teeth with a pitch of 12.7, and 4 M6 bolts will help to fix it. To avoid unwanted external influences, it is advisable to hide the chain and the system itself behind the body of the snow blower. After installing the star and bearings, the blades begin to be welded to the shaft, which will scoop snow. This requires 12 steel strips, 6 strips on each side of the shaft.

The screw can be made in two versions. The first is to create a one-piece structure (like an ice screw), you can order it at the factory or from craftsmen, or create it yourself. But the simplest option would be cutting steel into "horseshoes". This will make it easier to attach the auger to the pipe. And the design in terms of strength will not differ from a professional counterpart. To improve the performance of the snow blower, the auger blades must have teeth.

They can be cut with a grinder. Now we attach the blades to the wings. This can be done with M6 bolts. But it is worth remembering that each bolt is subject to unwinding during operation, therefore it is better to rivet the ends of the bolted connection.

The rotor made must have 2 duralumin blades, which are made of 2 mm steel. You can replace them with stainless steel blades, then the mechanism will be more durable.

Blades must be installed symmetrically. This will ensure uninterrupted operation during snow removal, as well as protect the blades from mechanical damage. After installation, the design should be symmetrical and balanced.

To connect the gearbox to the transmission star, it is necessary to replace the drive star of the gearbox with a 17-tooth one, with a step of 12.7, in the process of finalizing the engine. The star is mounted on the cardan shaft, at the end of the second knee.

When constructing the wheelbase, it should be borne in mind that its design must have an axle with two bearings, on which the rollers will be installed in the future. Or you can use pins. To do this, they are welded to the ends of the pipe. Now you can use wheels with integrated bearings. This method will be easier, since repair and replacement of wheels will take much less time. The wheels and axles are fastened with M10 bolts.

The last thing to do is to guide the snow. To do this, a sleeve should be welded to the bucket, along which the collected snow will be sent out.

Important: the diameter of the sleeve should not be too small, nor should it have complex bends. Otherwise, the snow in this case will constantly clog it, which will complicate work on the street..

By the onset of winter, you can try to make a snow blower from a chainsaw with your own hands. This will save a man from monotonous work using a shovel and speed up the cleaning process several times. To create such a snow blower, large financial costs are not needed, especially if the house already has a chainsaw.

A chainsaw snow blower will significantly speed up the daily work of clearing the area from snow.

In order to make a primitive snowplow, you must correctly choose the main method of cleaning the snow mass. It depends only on the ingenuity of the do-it-yourselfer what he will use as a working tool: a rotor, a fan or a simple blade (like a bulldozer).

Getting started on the device

If you have a chainsaw and parts from an old car, then you can start designing a snow blower. In order for the snow removal to be carried out efficiently, it is better to work a little and make a rotary apparatus. It is known from practice that units of this type are superior in efficiency to other types of machines.

In order to make a snow blower, you will first need a chainsaw, such as Friendship or Ural. Still need tools and parts, a list of which is given below. It is not recommended to make a complex device: a home-made snow blower must have high maintainability, that is, in the event of a breakdown, there must be access to any of its parts. Back to index

Chainsaw rotary snow blower

Such a device works as follows:

The moving auger, which has two input turns, moves the snow mass to the blade.
This part during operation throws snow to the side through a pipe.

Such an apparatus is capable of capturing the layers to be removed on an area of 50 x 40 cm. If it is necessary to increase the productivity of the unit, then it is possible to slightly increase the size of the rotor (by 30%) and make appropriate changes to other parts. The assembly technology is as follows:

From a sheet of iron or steel, it is necessary to weld a box of the required dimensions. They should be chosen so that the box is more calm. If this is not done, then during operation the machine will rumble due to friction of parts.
A hole is made in the box with a diameter of 16 cm. It is necessary for the output of the pipe. If you draw a conclusion of a smaller caliber, then during operation it may become clogged.
For the screw shaft, you can use a finished, steel pipe, which is bought on the construction market. The tubes of the front pillars from a car, for example, a VAZ 2210, are also suitable. Two blades (metal) measuring 14 x 10 cm must be welded onto it. 2 blades are screwed on both sides next to them, which are made in the form of a spiral with two links. They can be purchased at the construction market or made from a sheet of steel 2-3 mm thick.
The shaft must be made composite, of two halves. It can also be made from corners that are welded along the fold line. but using a cut pipe gives better results.
The finished auger must be installed on bearings of the appropriate diameter.
All moving parts should be located under removable elements, which will facilitate the cleaning of mechanisms after work is completed.
The main, driving auger and motor are electrical, therefore, to protect them, the rotor must rotate in sealed bearings.
The blades must be installed in the pipe hole, and the auger - in the box. Now they are connected with an asterisk that can be removed from the bike
Now you need to attach the resulting device to a gasoline saw. When carrying out this operation, you can’t rush - you need to correctly calculate the gaps.
Weld the main frame. An electric motor is installed on it with the help of channels and bolts and connected by a chain to the screw sprocket. Then a gasoline saw is fixed on the base. The outputs of its generator are connected to the electric motor. You can also draw a direct conclusion from the chainsaw - then its sprocket must be connected by a chain to the gearbox, which, in turn, is connected by a chain drive to the auger shaft. The choice depends on the person who works on this device, and the ability to purchase or get the right parts.
Sidewalls made of thick plywood cover all the main mechanisms of the apparatus. For this, a chipboard sheet with a thickness of 1-1.5 cm is suitable.
They center the auger, check by hand the ease of rotation of the shaft, blades in the pipe hole.
It is possible to install a homemade snow blower on wheels, but they can get stuck in deep snow. Therefore, it is best to install the unit on skis. They are made from two blocks of wood and fixed on the sides of the apparatus. To make them glide better, you need to put thick plastic pads on the boards. They are made from boxes for electrical wiring.
Now we need to take care of the appearance of the made unit. It can be dyed in any desired color.
After that, you need to install the pipe in place and pour gasoline into the tank. The apparatus is put into action and, slowly bringing it to a snowdrift, they allow the auger to enter into the depths of the snow mass. Snow dust should fly out of the pipe to the side.
If everything is in order, then you can start clearing the road from snow drifts.

Currently, there are a large number of different equipment that facilitates work in the house and on its territory. In winter, snow removal equipment is especially popular. The structure of the snow blower is simple, so you can, with the necessary materials, assemble a snow blower from a chainsaw with your own hands.

Advantages and disadvantages of a homemade chainsaw snow blower

Advantages of a homemade snow blower:

Save money - any chainsaw costs significantly less than a snow blower.
Technically, a home-made device is practically not inferior to an industrial machine.
The ability to upgrade the snow blower.
Availability of materials and tools.

The main disadvantage when assembling a snow blower with your own hands is the lack of a mechanism for moving - you will have to carry the car in your hands.

Chainsaw snow blower - dimensions

Even a novice can make a snow blower with his own hands, you will need improvised material that can be found in the garage, and time. As a result, the assembled tool will not be inferior in its characteristics to models that can be bought in a store.

Main Assembly Components

To create a homemade snow blower, you will need a minimum set of tools:

low power chainsaw;
consumables (screws, nuts, etc.);
several pipes;
sheet metal (for blades and blades);
stars and chains from motorcycles;
a welding machine and a power plant (even the simplest engine from a Soviet chainsaw may work).

The main assembly steps are welding the frame, auger, snow blower body and creating a snow removal mechanism. The snow blower works as follows: a moving auger moves the snow to the blade, which is then thrown to the side with a pipe. Moving parts must be made removable, this will make it easier to clean the device.

Frame creation

To assemble the frame structure, you need to select materials in advance. Pipes of equal diameter are required, they are welded to each other. You should carefully assemble 2 longitudinal pipes, which are both an element of the frame itself and the skids of the snow blower. For this reason, the pipes have to be cut at an angle, and their holes welded so that snow does not penetrate there. When hit, the snow will begin to melt, the moisture will cause the process of corrosion inside and the machine may fall apart.

The other 2 parts are welded transversely and installed at the back, since the power unit is attached to them. The first pipe is placed in the rear position, the second - at a distance of less than 700 mm. The result is a structure in the form of the letter "p" with two longitudinal pipes installed at the bottom. An electric motor is installed on the frame with the help of channels and bolts, which later needs to be connected to the auger chain. The motor must be installed in the same plane as the drive and driven sprockets.

As an electric motor, a motor from a Soviet chainsaw can be used. The motor is pulled out of the chainsaw and modified. The standard drive sprocket is changed to a small star.

Manufacturing of auger and drive

The auger is the main mechanism of the machine. To make it, you need a tube with a small diameter (you can use a shaft 80 cm long). Tubes from a car are also suitable for the shaft. It is important to correctly match sealed bearings to the shaft.

In a metal two-centimeter sheet, you need to make 4 circles with a diameter of 300 mm of equal size. Next, you need to find their center and make holes in it with a diameter of 220–230 mm. On these circles, you need to make an incision, thanks to which it will be possible to make a coil from the circles.

It is necessary to identify the central part of the shaft. 2 plates 14 * 10 cm are welded to it, located in parallel. They act as blades and are required in order to throw snow to the side while clearing the area.

Screw tapes are welded on both sides of the blades. They can be purchased at the store or made independently from a steel sheet 2-3 mm thick. They need to be placed on the shaft so that all 4 parts are directed to the central part of the auger. To increase the efficiency of the device, the blades should be with teeth, cut with a grinder.

Snow blower body

The body is made of round sidewalls, exceeding the dimensions of the screw by about 70 mm. A metal sheet 1 mm thick is welded to them, which must first be bent into a semicircle. Holes are made in the sidewalls along the central part, into which the screw is inserted. From the outside of the auger, bearings are put on the shaft.

Stages of snow removal assembly

For snow removal, you will need an aluminum tube with a diameter of at least 150 mm and a length of 10 mm and sheet metal. A box is formed from a metal sheet, and the tube is used as the basis for snow removal. To fix the pipe in the auger, you need to make a hole, taking into account its diameter, but it should be located behind the blades. The tube is fixed with bolts, a box is put on top of the assembled model.

Connection of all parts

The final step in creating a chainsaw snow blower is to assemble all the components into a single structure. The body with the auger is welded to the longitudinal parts of the frame.

A chain is pulled onto the drive (suitable from a motorcycle). It can be installed in different ways - it can be tensioned by moving the power apparatus or using a tension sprocket attached to the screw fasteners to the auger. The first method can be used when it is possible to move the motor longitudinally and fix it in one place.

To the design of the chainsaw, you will need to make a handle from the pipes with which the snow blower will be controlled. It is necessary to bring the damper control on the motor to it. You can put the snow blower on wheels, but in deep snow they can get stuck, so the device should be put on skis. For this, 2 blocks of wood are taken and fixed to the side of the snowplow.

Before starting work, you should check that all parts are assembled correctly, the wires are connected correctly, the blades do not touch the body.

Small-sized snow blowers, which allow automating the laborious process of clearing snow, are in great demand. But what if there is simply no money to buy a snowplow?

the only way out is the construction of a homemade snow blower from what can be found in almost every garage of a thrifty owner. For example, chainsaw, which is available to many people, especially in rural areas.

Principle of operation

The design of a factory snow blower is quite simple. The main driving force is the motor, the quality of snow removal, the throwing range, etc. will depend on the power of which.

In addition to the engine, snow blower includes:

A housing made of metal or plastic that protects the working units from the outside environment.
Screw mechanism, consisting of a shaft and screw parts.
Outlet pipe through which snow is ejected to the outside.
If the system is two-stage, then in addition to the auger, an impeller (rotor mechanism) is also used, which ejects snow into the outlet pipe.
Elementary control systems, handles, clutch, etc.
Depending on the configuration, there may be a wheelbase, tracks or skis.

The principle of operation of a homemade snow blower will be no different from the store version. It also includes auger will be included, which is directed by screws to the center of the shaft. He directs the snow cover to the blade, which transfers the mass further to the outlet pipe.

If a rotor is provided in the design, then the incoming snow from the blade first falls on it. It performs additional processing of the snow mass, after which it is sent to the pipe.

Then the snow is thrown out to a certain distance (up to 12 meters).

Made homemade chainsaw snow blower has its advantages:

By making a snow blower with your own hands, you will save a lot of money that you could spend on buying a new snow blower. At the same time, even if you have to buy the chainsaw itself (see which chainsaws are good), you will still remain in the black.
A do-it-yourself snowplow made from a Druzhba chainsaw or other models will have similar performance as purchased counterparts.
The remaining parts of the body, the screw mechanism and other structural components are made from handy tools, such as metal pipes, iron sheets, etc. Again, this is about saving money.

For more information, see the video below:

The only drawback will be the fact that a homemade snowplow from a chainsaw it will not be possible to install the mechanism responsible for the self-propelled structure. But if you provide for a kind of sled or skis at the bottom of the unit, then this task will not be so difficult.

The chainsaw snow blower has other features:

As an outlet pipe, you can use almost any plastic pipe, the diameter of which will be at least 16 cm.

The control knob can be made independently, from any metal tube.

The width of the bucket will depend on the power of the chainsaw engine. If it is powerful enough, then the width of the bucket can be increased.

Due to the fact that a homemade snow blower made from a chainsaw is not self-propelled, it is better provide a kind of sled for better movement of the unit on the snow cover. You can use ordinary wooden bars, corresponding to the length of the frame.

They can be attached to a plastic base, which will improve the running performance of the snow blower.

Can be distinguished a few tips assisting in the operation of the unit:

To prevent foreign objects from entering a running engine, special safety bolts can be installed to eliminate this threat.

After the first start of the unit, it is necessary to check all connections of the snow blower. If required, tighten all nuts until snug.

Make preference towards closed type bearings so that the snow mass does not get inside the housing.

Do not try to remove heavily packed snow. Make a preliminary preparation of the coating with a hand tool.

Conclusion

Building a homemade snow blower from an existing chainsaw is a fairly optimal way out of a situation where there is not enough money to buy a snow blower in a store.

Taking into account the fact that the cost of even the cheapest unit can be at least 15 thousand rubles, this issue is quite acute. (read about choosing a petrol snow blower)

Using a chainsaw engine is also good because its power is enough for cleaning quite large volumes of snow. At the same time, the power of a home-made snow blower is almost identical to that available from store models (see the Lynx snow blower).

A large amount of snow falls on the territory of the Russian Federation in winter. In some places, precipitation reaches a height of a meter or more. It is in such conditions that a snow blower is simply an irreplaceable thing. The market offers a wide range of snowplows of various capacities of household and semi-professional types. However, not everyone will be able to allocate a sufficient amount of money to buy expensive foreign cars. One of the options for getting a snowplow can be a homemade version made from a chainsaw.

How to assemble a snow blower with your own hands?

Having understood the design of snowplows and familiarized yourself with the drawings from the Internet, you can build a snowplow with your own hands using a chainsaw. Even a beginner can easily master such a homemade product. Having at hand a number of necessary components, tools and spare parts, you can design a homemade snow blower.

The only difficulty you may encounter is finding the power unit. However, for these purposes, any motor of domestic or foreign chainsaws is suitable. On forums and on many sites, you can find various diagrams and drawings that show which components are needed and how to connect them together.

Choosing a chainsaw for a homemade snow blower

The power and performance of a snow blower is directly dependent on the engine you choose. This main element is removed from the chainsaw. The higher the power of the saw, the better. Engines in household models are two-stroke, power varies from 2 to 10 horsepower. For a homemade snow blower, 5 horsepower will be enough. Below we consider the most popular brands of chainsaws, which are often used for a homemade snow blower.

Motor saw “Friendship”

This chainsaw was developed back in the time of the USSR, in 1950, after which they began to mass-produce in the Soviet space. Since then, the technical indicators and characteristics of the saw have become significantly outdated. The weight of the unit is 12 kg, in addition, the saw has large dimensions. Experienced owners say that the first saws, which were assembled in the first decade of the plant's existence, still work properly.

However, chainsaws manufactured after 1990 are distinguished by frequent marriages, regular breakdowns, malfunctions and a short service life.

Petrol saw “Ural”

Another representative of the domestic production of chainsaws. Tools "Ural" can be called a kind of improvement saws "Friendship". With the same weight, the Ural has more power of a two-stroke gasoline-powered engine (5.5 horsepower) and smaller dimensions. In this regard, the performance of these devices is much higher.

German chainsaw "Stihl"

Imported sawing equipment is often much better in terms of quality and performance. Foreign factories, such as the German concern "Stihl" are always trying to produce technological innovations. Of course, this also affects the cost of equipment. "Shtil" is one of the most popular companies among the Russian population, as it has high capacity, excellent quality, long service life and a relatively low price.

What does it take to make a snow blower?

Next, we will use an example to consider assembling a snow blower with our own hands based on the Ural chainsaw. The fact is that it is in this chainsaw that the inertial clutch in some cases acts as a kind of fuse, protecting the rotor from breakdowns and malfunctions. The equipment motor is equipped with a 1:2 reduction gear.

Our goal is to create reliable and productive do-it-yourself snow removal equipment on a budget.

To do this, we will try to use affordable and cheap materials:

aluminum and metal pipes;
metal sheets;
bearings and fasteners;
chainsaw motor;
welding;
hand tools.

The assembly process itself is not particularly difficult, so every man could successfully make a snow blower with his own hands at home. You don't need any special skills for this. If you don't know how to properly manage some tools, you can watch a couple of video tutorials on this topic.

Schemes, drawings and assembly principle of a homemade snow blower

On the Internet, on forums and discussions, you can find many drawings of a do-it-yourself chainsaw snow blower. In our example, consider the following schemes:

The engine itself must be placed on the longitudinal axis for reliability and quality of work. In addition to the motor, use the fuel tank from the Ural chainsaw, fixing it to the steering column with two bolts. Handles for control can be taken from the motorcycle. To create a bucket, you will need pipes with a square section of 20x20x1.7 mm, from which the frame is designed and covered with a tin sheet, the thickness of which is not less than 0.5 mm.

Below are drawings for assembling the most important part of the snow blower - the auger rotor.

You can make an auger with your own hands from the following parts:

shaft in the form of a pipe ½;
mounted on the shaft of the driven sprocket;
two bearings fixed on the housing;
rotor wings 30x4 mm;
rotor blades, 2 pcs;
screw blades, 8 pcs;
wings for blades, 4 pcs;
support corners, 2 pcs.

The blades can also be made from duralumin sheet, the thickness of which is 4 mm. Jigsaws cut out a kind of horseshoe. You will greatly facilitate the fastening process if you cut them out individually, and not as a single piece. Below are the drawings of the rotor auger blades.

As described above, when creating the blades, it is better to cut them separately, in the form of horseshoes and attach to the shaft. However, some users cut out rings from a metal sheet using a grinder and a jigsaw, and then stretch them into a spiral with a vise. This method is more effective, but significantly more difficult in terms of physical activity.
