Winter period in addition to frost brings us a large number of snow. Sometimes its quantity is so large that it simply cannot be removed with a simple shovel. Therefore, a person creates technology that can make his life easier and save time for other things.
One such mechanized innovation was snowblowers. But any technique costs a lot of money, so home craftsmen began to think about what they could use to create them with their own hands. We thought about it and created snow blowers made from chainsaws. A homemade snow blower made from chainsaws significantly reduces the time spent on snow removal, and also allows you to more thoroughly clean your territory from precipitation.
This article will describe options for creating snow removal equipment with your own hands. It turns out that you can make your own snow blower from a Druzhba chainsaw, which will significantly save your accumulated funds due to the fact that the scheme for creating a snow blower is very simple, and the parts can be found at a flea market or in your grandfather’s garage.
To solve our problem, there is no need to purchase the most powerful units; a low-power chainsaw, for example, with a power of five hp or more, will be sufficient. With.
An example of a homemade snowplow based on a URAL chainsaw
We'll tell you how to do it homemade snow blower with your own hands from a Ural chainsaw. The layout of this unit is very good. Its design provides a high-quality transmission that protects the saw from damage.
And the inertial clutch allows you to protect the insides of the saw from damage by external objects. So, if a foreign body gets inside, the saw immediately turns off, which allows you to clean it and avoid breakdowns. A DIY snow blower made from a chainsaw does not require complex parts; its construction does not require hours of grinding complex mechanisms or buy them.
For production you will need:
- chainsaw "Ural", it acts as a donor;
- sheet metal 2 millimeters thick, necessary for the manufacture of blades and paddles;
- stainless steel sheet 1 mm thick;
- pair of bearings for 48;
- arcs and crossbars (20x20), can be taken from an old greenhouse;
- consumables: nuts, washers, bolts;
- sprockets and chains from old Soviet motorcycles;
- Rubber handles for easy operation of the snow blower.
As can be seen from the list above, homemade products do not require the purchase of new materials; it is enough to rummage around in the garage or go to the nearest flea market.
Assembling a snow blower
The design of a homemade snow blower made from a 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 snow scooping, the motor must be placed strictly in the center of the device. A subsequent modification of the engine is an addition in the form of a gas tank. For convenience, it is attached to the steering support. This can be done using bolted connection. You can also take the throttle handle with a cable from the motorcycle, this will ensure unhindered control of the engine throttle.
In order for the snow blower to gain its functionality, 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 for its assembly.
To create a bucket, you will need square pipes measuring 20x20x1.7 millimeters. A frame is assembled from them, which will later be covered with galvanized steel, which will protect the bucket from rusting and rotting.
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 using simple aluminum rivets.
For ease of control, a metal plate should be welded to the bucket structure. It will ensure unhindered movement of the bucket through 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 prevent snow from sticking to the plate.
The most important element in the design of a snow blower is its shaft. Its design consists of a pipe with welded screws. When designing the shaft we will need:
- steel pipe with a cross 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 for creating a shaft;
- blade wings;
- support corners in the amount of two units.
The shaft design involves a rotor with parallel welded screws facing in different directions. First you need to take steel pipe with parameters 22x2 millimeters, and a length of 570 millimeters. Bearings must be placed at the ends of this pipe. To do this, weld the trunnion onto the end of the pipe and then install the bearings there. Bearing parameters: sizes 40/16/16, s closed type designs.
A further design involves installing an additional star in the center of the shaft. With its help, torque from the motor will be transmitted to the shaft. Connecting these 2 elements will be 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 secure it. To avoid unwanted external influences, it is advisable to hide the chain and the system itself behind the snow blower body. After installing the star and bearings, the blades that will scoop snow begin to be welded to the shaft. This requires 12 steel strips, 6 strips on each side of the shaft.
The screw can be manufactured in two versions. The first is to create a one-piece structure (like an ice drill); it can be ordered from a factory or from craftsmen, or you can create it yourself. But the simplest option would be to cut the steel into “horseshoes”. This will make it easier to attach the auger to the pipe. And the design will not differ in strength from its professional counterpart. To improve the performance of the snow blower, the auger blades must have teeth.
They can be cut using 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, so it is better to rivet the ends of the bolted connection.
The made rotor must have 2 duralumin blades, which are made of two-millimeter steel. They can be replaced with blades made from of stainless steel, then the mechanism will be more durable.
The blades must be installed symmetrically. This will ensure uninterrupted operation during snow removal, and will also protect the blades from mechanical damage. After installation, the structure should be symmetrical and balanced.
To connect the gearbox to the transmission sprocket, it is necessary to replace the gearbox drive sprocket during engine modification with a 17-tooth one, with a pitch of 12.7. The star is installed on the cardan shaft, at the end of the second bend.
When constructing a wheelbase, it should be taken into account that its design must have an axle with two bearings, on which the rollers will be installed in the future. Or you can use trunnions. To do this, they are welded onto the ends of the pipe. Now you can use wheels with built-in bearings. This method will be easier, since repairing and replacing wheels will take much less time. The wheels and axles are fastened with M10 bolts.
IN last resort the snow guide should be addressed. To do this, a sleeve should be welded to the bucket, along which the collected snow will be sent out.
Important: the sleeve diameter should not be too small, and also have complex bends. Otherwise, in this case, snow will constantly clog it, which will complicate work on the street.
Currently, there is a large number of different equipment that facilitate work in the house and on its territory. In winter, equipment that helps remove snow is especially popular. Structure snow blower is simple, so you can, having necessary materials, assemble a snow blower from a chainsaw with your own hands.
Advantages and disadvantages of a homemade chainsaw snow blower
Pros of a homemade snow blower:
- Saving money - any chainsaw costs much less than a snow blower.
- Technically homemade device practically not inferior to an industrial machine.
- Possibility to upgrade the snow blower.
- Availability of materials and tools.
The main disadvantage of assembling a snow blower with your own hands is the lack of a mechanism for moving it - you will have to carry the machine in your hands.
Chainsaw snow blower - dimensions
Even a beginner can make a snow blower with his own hands; you will need available materials that can be found in the garage and time. As a result, the collected product will not be inferior in its characteristics to models that can be bought in the 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 paddles);
- motorcycle stars and chains;
- welding machine and power point(may even be suitable simplest engine from a Soviet chainsaw).
The main stages of assembly 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 using a pipe. Moving parts must be made removable to make cleaning the device easier.
Creating a Frame
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 must be welded so that snow does not penetrate there. If it gets in, the snow will begin to melt, the moisture will cause a corrosion process inside and the car may fall apart.
The other 2 parts are welded transversely and installed at the back, since the power unit. 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. An electric motor is installed on the frame using channels and bolts, which later needs to be connected to the auger chain. The motor must be installed in the same plane with the drive and driven sprockets.
A motor from a Soviet chainsaw can be used as an electric motor. The motor is removed from the chainsaw and modified. The standard drive sprocket is replaced with a small sprocket.
Manufacturing of screw 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 passenger car. It is important to select the correct sealed bearings for the shaft.
In a two-centimeter metal sheet you need to make 4 circles with a diameter of 300 mm equal size. Next, you need to find their center and make holes in it with a diameter of 220–230 mm. You need to make a cut on these circles, thanks to which you can make a coil out of the circles.
It is necessary to identify the central part of the shaft. 2 plates of 14*10 cm, located in parallel, are welded to it. They act as shovels and are required to throw snow aside while clearing the area.
Screw strips are welded on both sides of the blades. You can buy them at the store or make them yourself from 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 serrated, cut using a grinder.
Snow blower body
The body is made of round sidewalls that exceed the dimensions of the auger by approximately 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 auger is inserted. WITH outside Bearings are placed on the auger shaft.
Stages of snow removal assembly
For a snow drain 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 a snow drain. To secure 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 secured with bolts, and a box is placed on top of the assembled model.
Connecting all the parts
The final stage of creating a chainsaw snow blower is to assemble all the components into a single structure. The housing with the auger is welded to the longitudinal parts of the frame.
A chain is pulled onto the drive (suitable from a motorcycle). You can install it different methods– tension by moving the power apparatus or using a tension sprocket attached to the bolted fastenings to the auger. The first method can be used when it is possible to move the motor longitudinally and secure it in one place.
For the chainsaw structure, you will need to make a handle from pipes, with the help of which the snow blower will be controlled. You need to use it to control the damper on the motor. You can put the snow blower on wheels, but in deep snow they can get stuck, so the device should be placed on skis. To do this, take 2 pieces of wood and secure them to the side of the snowblower.
Before starting work, you should check that all parts are assembled correctly, the wires are connected correctly, and the blades do not touch the body.
When winter comes, you can try making a snow blower out of 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 you do not need large financial expenses, especially if there is already a chainsaw in the house.
A chainsaw snow blower will significantly speed up the daily work of clearing snow from the area.
In order to make a primitive snow blower, you must correctly choose the main method of removing snow mass. It depends only on the ingenuity of the home-made worker what he will use as a working tool: a rotor, a fan or a simple blade (like a bulldozer).
Start of work 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 snow clearing 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 machines of other types.
In order to make a snow blower, you will first need a chainsaw, for example “Druzhba” or “Ural”. You also need tools and parts, the list of which is given below. It is not recommended to make a complex device: a homemade snow blower must have high maintainability, that is, if it breaks down, there must be access to any of its parts. Return to contents
Rotary snow blower made from a chainsaw
This device works as follows:
- A moving auger, which has two input turns, moves the snow mass to the blade.
- During operation, this part throws snow to the side through a pipe.
Such a device is capable of capturing layers to be removed over an area of 50 x 40 cm. If you need to increase the productivity of the unit, you can slightly increase the size of the rotor (by 30%) and make corresponding changes to other parts. The assembly technology is as follows:
- A box must be welded from a sheet of iron or steel required sizes. They should be chosen so that the box is larger than the calm. If this is not done, then during operation the machine will rumble due to friction of parts.
- A hole 16 cm in diameter is made in the box. It is needed to remove the pipe. If you make a lead of a smaller caliber, it may become clogged during operation.
- For the auger shaft, you can use a ready-made steel pipe, which is purchased on the construction market. Tubes of the front pillars from a passenger car, for example, a VAZ 2210, are also suitable. You need to weld two blades (metal) measuring 14 x 10 cm onto it. On both sides, next to them, screw 2 blades, which are made in the form of a spiral with two links. They can be purchased on 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 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 make it easier to clean the mechanisms after finishing work.
- The main, driving auger and motor are electric, so 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 by an asterisk, which can be removed from the bicycle
- Now you need to connect the resulting device to a gasoline saw. When carrying out this operation, you cannot rush - you need to correctly calculate the gaps.
- The main frame is being welded. An electric motor is installed on it using channels and bolts and connected by a chain to the auger sprocket. Then strengthened on the base gasoline saw. The terminals of its generator are connected to the electric motor. You can also make a direct connection from the chainsaw - then its sprocket must be connected by a chain to the gearbox, which, in turn, is connected chain drive with auger shaft. The choice depends on the person working on the device and the ability to purchase or obtain the necessary parts.
- Sidewalls made of thick plywood cover all the main mechanisms of the device. A sheet is suitable for this Chipboard thickness 1-1.5 cm.
- Align the auger, check with your hand that the shaft and blades rotate easily in the pipe hole.
- You can 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 pieces of wood and secured to the sides of the apparatus. To make them slide better, you need to put thick plastic pads on the boards. They are made from electrical wiring boxes.
- Now we need to take care of appearance made unit. It can be painted in any desired color.
- After this, you need to install the pipe in place and pour gasoline into the tank. The apparatus is activated and, slowly bringing it to the snowdrift, the auger is allowed to enter deep into 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 of snow drifts.
Sometimes in winter there is so much snow that it is impossible to remove it with a regular shovel. When living outside the city we are talking about quite large areas. To facilitate cleaning work, you need to use special equipment. However, acquiring it is very expensive. Many home craftsmen recommend making a snow blower from a chainsaw with your own hands.
This solution will not only allow you to quickly and inexpensively get rid of snowdrifts, but also give a second life to an old tool instead of throwing it away.
Advantages of the device
Homemade snow blower from a chainsaw has several advantages. In particular, the following should be noted:
Do-it-yourself snow blowers can be made from other products, in particular, walk-behind tractors and more. The most popular option among craftsmen is to make such a device from a Ural brand chainsaw.
What do you need for work?
Snow removal machine assembly process will differ depending on which unit this is based on. If we consider the Ural chainsaw as a working material, then it is good because it includes a high-quality transmission that protects the saw from damage. Thanks to the inertial clutch, the insides are reliably protected from external influences. For example, if a foreign body gets inside, the saw immediately turns off, so it can be cleaned and avoid damage.
This chainsaw is good because the machine based on it does not require the use of complex parts and tucks or the purchase of complex mechanisms.
To work you need to prepare the following:
There is no need to purchase any expensive new materials; most of the listed tools and parts are available in the arsenal of almost everyone home handyman. If they are not available, then you can buy them at a flea market for a very affordable price or ask your friends.
A homemade snow removal design includes several key components. Among them:
- engine;
- wheelbase;
- cardan shaft;
- bearings;
- leading star.
First you need to provide strong fastening of the structure. The motor should be placed strictly in the center to prevent uneven snow scooping or distortions. It is supplemented with a gas tank, which for convenience is attached to the steering support using a bolted connection. You can take a throttle handle with a cable from an old motorcycle, which will allow you to easily control the engine throttle.
In order for the snow removal device to work, you will need to weld the frame. There is no need to use complex drawings for this; everything is much simpler than it might seem.
For the bucket you will need square pipes with parameters 20 by 20 by 1.7 mm. Based on them, you need to assemble a frame, then cover it with galvanized steel so that the bucket does not rust or rot in the future. The steel must have a thickness of 5 mm to avoid mechanical damage. Metal sheets
Attached to the frame with aluminum rivets. To make the structure easier to use, you need to weld a metal plate to the bucket, which will allow it to move easier in the snow. The plate should have a size of up to 60 cm in width and up to 4 cm in length, respectively. It is better to cover it with polyethylene: then snow will not stick to it.
Shaft design
Val is one of the key elements in the design of the harvesting machine. It consists of a pipe base to which screws are welded.
For the shaft you will need to take:
- steel pipe;
- a driven star welded to it;
- bearings for mounting inside the screw pipe;
- wing rotors and two rotor blades;
- augers;
- blade wings;
- two support corners.
The cardan shaft is a rotor to which augers are welded parallel to each other and point in different directions. First you need to take a steel pipe, at the ends of which bearings will be installed. For this purpose, a trunnion is welded to the end of the pipe, and then closed-type bearings are mounted on it.
Then you need to install it in the center of the shaft extra star, which will transmit torque from the motor to the shaft. The elements will be connected by a chain; it can be taken from an old motorcycle. Such a star must have 33 teeth, observing a pitch of 12.7, and it is secured with special bolts. To ensure that the circuit and other parts of the system are not exposed to negative external influences, it is recommended to provide a housing for the structure.
Once the star and bearings are installed, snow clearing blades are welded to the shaft. You will need 6 steel strips located on each side of the shaft.
Augers are manufactured in different ways. They can be solid and can be ordered or made yourself. The easiest way is to cut the steel into “horseshoes,” which makes it easier for the auger to attach to the pipe. In terms of strength, the design will be practically no different from the factory one. To improve the performance of the machine, it is necessary to provide teeth for the auger blades. You can cut them with a grinder. The blades are then attached to the wings using M6 bolts. All bolts will need to be unscrewed; accordingly, the ends of their connections must be riveted.
The finished rotor should have two duralumin blades based on steel 2 mm thick. Instead of steel, you can use stainless steel, which will be more durable.
The blades are placed symmetrically, thanks to which they will be reliably protected from mechanical influences. After installation, the structure should look balanced and symmetrical. To connect the gearbox and transmission sprocket during engine improvement, it will be necessary to replace the gearbox drive sprocket with a 17-tooth design in a pitch of 12.7. It is placed on the cardan shaft at the end of the second bend. When working with a wheelbase, you need to take into account that it must have an axle with a pair of bearings; rollers or axles are placed on them. They are welded onto the ends of pipes.
The wheels can be equipped with built-in bearings, in which case replacing or repairing them is much easier and faster. The axle and wheels are secured using M10 bolts.
The final touch to assembling the machine is installing the snow guide. A sleeve is welded to the bucket; after assembly, the snow will come out through it. If your snow blower engine is rated at 7 horsepower or less, it may fail during heavy snowfalls.
The Ural chainsaw and other brands can also be used for homemade production others useful devices. For example:
- lawnmowers;
- sawmills;
- water pump.
The key requirement for a particular device that is planned to be manufactured is that it must have a small-sized, powerful engine. Armed simple tools from a home workshop, you can make useful devices to make household work easier - in particular, a tool for removing snow in winter.
