Chainsaw snow blower. Construction and snow blower. Tips and tricks

As the owner of a summer house or private house, there is a need to remove large amounts of snow in winter. It is difficult to cope with such a volume with an ordinary shovel, and not every person can physically cope with it. It takes a lot of effort and time.

A good option is to buy a snow blower. The only problem is that a factory snow blower is expensive, and people only use it a few times a season at most. The rest of the time the equipment sits idle.

Therefore, an alternative solution appeared. These are homemade snow blowers that can be assembled from scrap materials. For example, it could be an old unnecessary chainsaw. The efficiency is high, the motor is quite powerful and productive. And the assembly itself is not difficult if you understand some of the nuances and strictly follow safety precautions.

Chainsaw snow blower

Large manufacturers of gardening and harvesting equipment offer consumers a wide range of products designed to make work in the garden, field or garden easier. But often high prices scare off potential buyers and make them think about an alternative option.

For example, during winter, especially in snowy areas, snow blowers are very popular. In order to clear the snow from the local area by hand, it will take a lot of time, but with the help of a small-sized tool the job will be more fun. A walk-behind tractor with special attachments can come to the rescue. However, some craftsmen make their own snow blowers from a chainsaw and get a small but functional workhorse, which is much cheaper in cost.

Helpful Tips and Warnings

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

Sleds for moving on snow

You can attach a plastic base to them, which will improve the running performance of the snow blower.

There are several tips to help you operate the unit:

• To prevent foreign objects from getting into a running engine, you can install special safety bolts that eliminate this threat.
• After starting the unit for the first time, you need to check all connections of the snow blower. If required, tighten all nuts fully.
• Give preference to closed type bearings so that snow does not get inside the housing.
• Do not try to remove heavily compacted snow. Pre-prepare the coating using hand tools.

Following certain tips will help you significantly extend the service life of the device without loss of performance.

Theoretical aspect

Proceed to work only after preliminary development of the plan and complete readiness to make a snow blower. Planning is the main stage at which all the necessary parts and drawings are prepared according to which the assembly will be carried out. With the help of a correctly drawn up drawing, it is almost impossible to spoil the design or fail to make a working unit. It is the diagram that will allow you not to miss an important node and secure everything in the right place.

The design of the snow blower consists of:

• Gas tank;
• Engine;
• Wheelbase;
• Cardan shaft;
• Bearings;
• Leading star.

Build process

All moving parts of the machine must be located under removable elements. This design will make it easier to clean the mechanisms after the work is completed. The auger is placed inside the box, the blades are placed inside the pipe hole. They should be connected using a sprocket, which can be removed from any bicycle. The resulting device must be connected to a chainsaw. We do not recommend rushing during this action, since it is very important to correctly calculate the gaps.

The electric motor is installed on the main frame using angles and channels while welding the frame itself. The electric motor must be connected with a chain to the auger sprocket. Next, the chainsaw is fixed on the base, the leads from its generator must be connected to the electric motor. Although, there is an option in which the output from the chainsaw is supplied directly. In this case, its sprocket must be connected to the gearbox using a chain drive. And the gearbox, in turn, must be connected by a chain to the screw shaft.

To cover all the main organs of the device, you should use the sides made of thick plywood. For example, a sheet of chipboard. Its thickness should be at least 1-1.5 centimeters. After the snow blower is assembled, you should carefully check that the auger is aligned correctly. Check with your hand whether the shaft rotates well and whether the rotor blades rotate easily inside the pipe.

Which chainsaw is suitable for a snow blower?

In order to make your own snow blower from a chainsaw, you will need, in fact, a saw. You can take any brand and model that is in stock. Craftsmen recommend using the Druzhba, Ural or Shtil saws, as they are most suitable in terms of technical characteristics and differ in the quality of their engines.

Friendship

The advantage of the Druzhba saw is its simplicity of design and therefore it is very convenient to disassemble. In addition, the tool does not have any unnecessary bells and whistles that modern saws can boast of and which only interfere with the assembly of the snow blower. But there are also disadvantages - the Soviet saw is heavy and outdated.

Chainsaw "Friendship"

Its technical characteristics are as follows:

• power – 1 kW;
• weight - up to 12 kg;
• 2-stroke engine;
• tire length – 45 cm;
• gasoline as fuel.

Types of snow removal equipment for the home with your own hands

Snow removal machines are designed for mechanical removal of snow cover in the required area. Their functions include collecting snow mass and throwing it back to the collection point. The engine that powers the car can be electric or gasoline. And the snow removal machine itself is divided into self-propelled (with tracked or wheel drive), manually controlled, single-stage and two-stage. To independently assemble such garden equipment, you can use a chainsaw engine, an electric motor or a walk-behind tractor, as well as various improvised materials that everyone probably has on their farm. Before you make a snow blower with your own hands, you should familiarize yourself with the types of such equipment and choose an acceptable option for yourself. The choice of snow blower design depends on many factors, one of which is the area of ​​the area that is supposed to be processed. Electric snow blowers are capable of clearing small areas near the house, for example, a porch or narrow paths. Such a unit is not suitable for clearing large areas of snow cover. In addition, its operation is not effective if there is ice or significant snowdrifts. On the other hand, such equipment is quite compact, easy to operate and convenient to store. Gasoline-powered self-propelled snowblowers do an excellent job of removing large amounts of snow from large areas. Moving independently, these vehicles have excellent maneuverability and a long ejection range. The equipment is quite large in size, but does not require any physical effort during operation.

Before you make a manual snow blower with your own hands, you need to keep in mind that non-self-propelled models are designed for cleaning small areas of freshly fallen snow up to 25-30 cm thick. They are mainly used for daily cleaning of sidewalks, garden paths and flat roofs. Such devices are quite maneuverable, however, when removing a dense layer, it will be difficult to control the equipment, since you will have to push not only the device, but also the thickness of the snow in front of it. Helpful advice! When assembling a non-self-propelled snow blower for your home with your own hands, you should use the lightest possible parts, since the equipment will work due to human efforts.

Making a homemade snow blower for your home with your own hands is an excellent opportunity not to spend money on purchasing expensive models from leading manufacturers and at the same time avoid labor-intensive clearing of snow from the area with a shovel. In addition, home-made equipment will become a source of pride for any owner of a country house or dacha. Assembling a homemade snow blower will not be difficult if you have an idea of ​​the operating principle of such equipment and its structure. To clear snow from the surface of paths and the yard of your own home, it will be enough to assemble an auger or rotary model. These are simple machines and anyone can make them. Making a combined homemade snow blower with your own hands is somewhat more difficult, but you can do it if you want.

Snowplows can be either self-propelled - on wheels or tracks, or non-self-propelled, the movement of which requires operator effort. Before you make a snowplow with your own hands, you need to decide on the type of engine. When equipping it with an internal combustion engine, you should take into account that it will be a fairly powerful unit that can operate on any surface of your site. However, the components and fuel for it are quite expensive. In addition, the disadvantages include the complex technical content of such equipment. As for a do-it-yourself snowblower with an electric motor, in this case you can use any motor from relatively powerful electrical equipment. A motor from a trimmer or electric saw will do. The advantages of such technology include the availability of electricity, and the disadvantages are the short range of action. To cover the entire area, you will need an extension cord or street wiring with several outlets.

Operating principle based on circuits

The figure shows a drawing of the simplest snow blower.

Diagram of the main parameters of a snow blower

To produce a snow blower, in the example given, a Ural chainsaw is used. To avoid distortions and the snow blower to drive smoothly, it is necessary to place the engine on an axis located longitudinally. You can use all the necessary parts of the chainsaw, such as the tank. It must be attached to the steering support. To control the throttle, use a regular motorcycle throttle.

Square pipes made of metal are used to construct the frame. Externally it should look like a bucket with two levers and a steering cross member. The lower part is 20x20x1.7mm, and the top is 10x10x1.7mm. Use galvanizing to cover the bucket. Moreover, choose a thickness of at least 0.5mm. All sheets are secured to the frame using rivets with a diameter of 5mm.

To facilitate the sliding of the bucket, you need to weld a sheet of metal measuring 600x40x4mm to the bottom.

The main part of a snow blower is the shaft

Shaft

Thus, the rotor consists of:

• Vala;
• Star mounted on the shaft (z=33);
• Bearings attached to the housing itself – 2 pcs;
• The rotor “wing” is a metal plate measuring 30x4 mm;
• Two rotor blades;
• Eight auger blades.

Features of the walk-behind tractor

Structurally, a homemade walk-behind tractor is a two-wheeled unit on a frame, producing up to 4 liters. s at an average speed of 2.5-2.7 km/h. Features, as well as operational tasks, are largely determined by the choice of power plant. If we are talking about a conversion from “Friendship”, the following parameters will distinguish it from a purchased walk-behind tractor:

• small size, lightness;
• savings on fuel and lubricants;
• the ability to assemble a unit tailored for specific work (required frame size, mounting unit).

A homemade walk-behind tractor can plow, hill up crops, harrow, mow or remove tops, and apply fertilizer. Due to its small size, it can be used in hard-to-reach places (for rocky, poor soil, the power of a homemade product may not be enough). It will be especially useful for those in whose area the strength and power of a large purchased walk-behind tractor will be excessive.

Types of snow removal machines

Snow removal equipment differs in two main ways:

• by type of management;
• by type of energy carrier.

Based on the type of control, the machines are divided into non-self-propelled and self-propelled. Non-self-propelled ones have an affordable price, compact dimensions and low weight, up to 35 kilograms. Such devices do not require a hangar for storage and can be transported in the trunk of a car.

Light snow blowers do not damage paving slabs. Note! Non-self-propelled snow blowers throw snow no further than 5 meters. They cannot cope with compacted snow and ice crust.

Self-propelled devices are much more expensive, but they also have great capabilities. The operator does not need to make any effort to control such equipment. Such a machine throws snow further, and the dimensions of the bucket allow it to clear large areas. Such devices can overcome dense snow. The size of the equipment requires the use of special premises for storage, and such a unit can only be transported in a truck or on a trailer.

The weight of a self-propelled vehicle starts at 70 kilograms

Depending on the type of energy carrier, cleaners can be electric or gasoline.

Let's look at them in comparison.
