If there is a walk-behind tractor or a motor-cultivator on the farm, the owner tries to use the equipment to the maximum at any time of the year. For example, in winter, the unit can quickly clear a large area of snow. But to perform these works, a prefix is needed for the walk-behind tractor. Factory-made attachments are not cheap, so craftsmen often make them themselves. Collect at home snow blower for walk-behind tractor there are four types.
The difference between homemade snow blowers by design
Home-made snow plows are considered versatile. They can be used as trailed attachments for a mini-tractor, walk-behind tractor or motor-cultivator. In the absence of traction equipment, the snow removal mechanism is equipped with an engine. From such a homemade product, a snowplow is obtained. Regardless of the used traction device, the design of each type snow blower remains unchanged:
- Blade - used only as an attachment for a walk-behind tractor or mini-tractor. Attach it to a bracket located on the frame of the traction mechanism.
- The auger snow plow can act as a nozzle or an independent machine, if the structure is equipped with an engine. Such a snow blower for a walk-behind tractor is considered the most effective.
- A rotary snow blower is also called an air or fan snow blower. It is also capable of working with its own motor or used as a nozzle.
- The auger or combined snow blower has the most complex design. It combines a screw and a rotor mechanism inside one housing.
The combined snow blower for the walk-behind tractor is the most productive, but it is very difficult to manufacture it. Most often, craftsmen prefer auger nozzles.
Re-equipment of a walk-behind tractor into a bulldozer
The simplest homemade snow blower for a walk-behind tractor, a blade is considered. Shovel is a sample. It is attached to a hook-on bracket on the machine frame, resulting in a small bulldozer. The plow is equipped with a mechanism that allows you to change the angle of rotation of the shovel to move the snow mass to the side.
Make such a snow blower for DIY walk-behind tractor can be from a piece of pipe with a diameter of 270 mm or an old gas cylinder. To do this, the workpiece is marked along the lines to make three segments. One of the elements is cut out with a grinder, after which the rods and the trailer mechanism are welded on the back side.
The principle of the blade is simple. When the walk-behind tractor with the snow blower moves forward, the shovel rakes the snow cover. And since it is installed at an angle, the snow is evenly shifted towards the side of the road. If the walk-behind tractor needs to return to the starting position, the blade is raised and the reverse speed is turned on. To continue harvesting, the shovel is again lowered to the ground and moves forward in first gear.
Auger snow blower
The snow blower for the auger-type walk-behind tractor has a high performance. The nozzle consists of a metal semicircular body - a bucket. Inside, the auger rotates on bearings. Its design resembles a part of a meat grinder. Circular knives are welded onto the shaft in a spiral. They consist of two halves, which converge in turns to the central part.In this place on the shaft there are rectangular plates - blades. Strictly above them, at the top of the body, a wide hole is made - a nozzle, which is connected with a branch pipe to a discharge sleeve and a guide visor. A fixed knife is attached to the bottom of the bucket for cutting layers of snow.
The auger-type snow blower motor-block works as follows:
- During the forward movement of the nozzle, a stationary knife cuts the snow cover, and it falls into the inside of the bucket. Here the auger crushes the mass with knives and at the same time moves it to the center of the body.
- The blades rotate with the auger and pick up the incoming snow. Next, they push it out through the nozzle.
- The operator adjusts the direction of the snow blowout with a visor.
To connect such snowplows with a walk-behind tractor, a trailed mechanism is used. The torque from the engine to the auger is transmitted by a belt or chain drive.
The body of a snow blower is easy to make. It is bent from any sheet metal. The sides can be cut even from thick plywood. The hubs are bolted in the center. Bearings mounted on the auger shaft will be inserted here. It is more difficult to make the drum with knives itself. In the photo, we propose to see the drawings of a snow blower for a walk-behind tractor with our own hands, or, more precisely, a diagram of the auger itself.
The structure consists of a shaft on which pins are welded along the edges. They are fitted with closed-type bearings. A chain sprocket is attached to one of the trunnions. A pulley can be used to connect with a belt.
Circular knives are cut from metal. First, rings are made, then they are sawn and stretched in different directions to form spiral turns. The knives are attached to the shaft towards the blades.
There are several options for creating knives:
- disks from a conveyor belt or car tires are suitable for cleaning loose and freshly fallen snow;
- steel discs with a flat edge will cope with caked and wet cover;
- serrated metal discs are capable of grinding frozen strata.
For a made auger with any knives, it is important that there is the same distance between the turns. Failure to do so will cause the snow blower to throw around.
Fan snow blower
To remove a small amount of loose snow, a fan-type snow blower is used for a walk-behind tractor. The main working element of the nozzle is the rotor. The photo shows his drawing.
The diagram shows that the rotor is a shaft structure on which two bearings are mounted. The impeller is an impeller with blades. There are five of them in the drawing, but you can put two, three or four pieces. Torque is transmitted from the walk-behind tractor through pulleys with a V-belt.
The rotor bearing hub is fixed to the end of the round body of the snow blower. It is often made from a metal barrel. To do this, cut off a part of the container 15–20 cm high together with the bottom. The impeller is mounted on the rotor shaft, which extends into the housing. A hole is cut out on the side shelf at the top, where a branch pipe with a guide visor is welded. To make a fan snow blower out of the walk-behind tractor, the attachment is coupled to the unit frame and a belt drive is equipped.
The principle of operation of the blower snow blower is based on the suction of snow. The guide vanes are welded to the front of the body. Moving forward, the nozzle captures the snow with them. Fan blades grind it and mix with air. The resulting mass is pushed out through the branch pipe by a strong air flow and flies out to the side at a distance of up to 6 m.
Combined snow blower
Consider in detail, how to make a snow blower do it yourself auger type, it makes no sense. This design consists of two connected attachments. The auger snow blower for the walk-behind tractor is taken as a basis, after which it is being finalized. According to the instructions considered, a fan nozzle is made, only the guide vanes in the front of the case are not welded. At this point, it is connected to the rear of the bucket of the auger snow blower.
During operation, the auger crushes the snow and feeds it into the fan nozzle housing. Here, a powerful air flow is formed by the impeller blades, which pushes the mass through the discharge sleeve.
