There are many drawings and projects on how to make a snow blower with your own hands, and this collection is constantly updated. This is due to the exclusive performance of the technique, as each craftsman makes his own adjustments. One rule remains unchanged for homemade products. Users recommend collecting a single-stage screw machine to residents of the middle lane. A two-stage screw-type unit is more difficult to assemble, but has a high performance. Such a snowplow is optimal for residents of snowy regions.
Features of the snowplow device
Any handmade snow blowers may have minor differences in the design of the mechanisms that make the machines exclusive. But the craftsman assembles the main working units using an already developed scheme. To find such a project, just dive on the Internet or contact a friend who has already made a snow blower for the house.
Let’s start the review of the snow blower device with the engine. It can be electric or gasoline powered. A machine with an electric motor is easier to manufacture, more economical to operate and requires virtually no maintenance. A snow blower with a gasoline engine is much more powerful, is not afraid of moisture, plus the machine becomes mobile due to the lack of attachment to an outlet.
A feature of the snowplow equipment is the presence of a rotor or auger. In combined models, both nodes are installed. The rotor is an impeller with blades rotating on bearings inside a steel casing. It’s easy to make. It is more difficult for snowplows to make an auger. Here you will need to develop drawings.
The screw assembly sequence is as follows:
- The shaft is made of a pipe, with trunnions for bearings welded at the ends, and two rectangular steel plates in the center. These will be the blades.
- Four disks with a diameter of 2 mm are cut out of thick rubber or steel 280 mm thick.
- A hole equal to the thickness of the shaft is drilled in the center of each blank, after which one side of the resulting ring is sawn.
- A spiral is bent from the cut disc and fixed to the shaft. On the left side, two disks are placed with directed turns towards the blades. The same is done on the right side of the shaft.
Bearings No. 203 or another suitable size are mounted on the trunnions. To mount the screw under the bearings, hubs are made from pipe segments. The blanks are fixed with bolts to the side shelves of the snow catcher housing.
The snow catcher bucket is made of sheet steel. To do this, take a strip 500 mm wide and bend it with an arc with a diameter of 300 mm. The sides can be sewn up with plywood or metal. A hole with a diameter of 160 mm is cut out in the center of the upper part of the snow collector, to which a sleeve is attached to eject snow. The finished structure is installed on the frame. It is welded from metal corners.
Now it remains to create a drive for the made snow blower. That is, you need to make sure that the auger rotates. There are several options for how to make a drive yourself:
- A gearbox can be used in a snow blower. It is installed instead of the blades, and the screw shaft is made of two halves.
- Belt transmission is provided by two pulleys. One is on the PTO of the motor, and the other is mounted on the auger shaft.
- A chain drive is similar to a belt drive, only sprockets from a moped or bicycle are used instead of pulleys.
- If a home-made snow blower is assembled with your own hands as a nozzle on a walk-behind tractor, you can make a combined drive. In this case, the motor shaft is connected to the intermediate gearbox by a belt drive, and the torque from the gearbox shaft to the auger is transmitted by a chain drive. The principle of such a connection is shown in the photo.
Of all the options, a belt drive is considered the simplest, so it is most often installed by craftsmen on their snow blowers.
Examples of self-made snow blowers
Now we will consider how a do-it-yourself snowplow is assembled with an engine from different equipment, and also consider the option of a nozzle on a walk-behind tractor.
Electric snow blower
The electric model of the snow blower is more suitable for giving, where you have to remove snow rarely and in small quantities. Typically, such machines are equipped with a single rotor instead of an auger, operating on the principle of a fan. After the snow is captured by the guide vanes, the fan blades mix it with air and throw it out under pressure through the outlet sleeve.
The rotor device is simple. You can make it according to the drawing.
For the impeller, a metal disk is taken and blades from a steel strip are welded onto it. They can be from 2 to 5 pieces. The shaft is machined on a lathe from a steel bar. Two bearings are mounted on it together with the hubs.
For the body of the snail, a part of a metal barrel is cut off from the bottom side with a height of 150 mm. A hole is cut on the side, where a branch pipe is welded for attaching the sleeve. A hole is drilled in the center of the bottom, the rotor shaft is inserted so that it is inside the snail. An impeller is placed on it. The rotor bearing hubs are bolted to the bottom of the barrel from the outside of the volute. Two rectangular sheets are welded from the front of the body. The guide vanes will capture the snow, while the fan will suck, grind and throw it out.
The finished rotary mechanism is placed on the frame, connected by a belt drive to an electric motor, and wheels from a wheelbarrow are used as a running gear.
Snow blower with petrol engine
Snowblowers with a gasoline engine are usually made with an auger mechanism or combined. The first option is much easier. We discussed the manufacture of the screw above. For a combined snow blower, you need to additionally assemble the rotor the same as they did for the electric model. Only guide vanes are not welded to the rotor housing. It is connected to the back of the auger snow box.
Any air-cooled engine will do. It can be two-stroke or four-stroke. The frame of a non-self-propelled machine is put on skis. It will be easier for the operator to push the snow blower over thick cover. If the power of the motor allows you to make a self-propelled machine, then you will need to fix the wheels to the frame and connect them with a drive to the PTO of the engine.
Hinge for motoblock
The simplest snow blower is a hitch on a walk-behind tractor. If there is a traction unit in the yard, then why create another machine with a stationary drive. As a hitch, you need to make a screw mechanism with blades for ejecting snow. The body of the snow collector is placed on the frame. Skis are attached below. Fasteners are welded on the back of the frame, with the help of which the nozzle will be coupled to the walk-behind tractor.
The drive is carried out by a belt drive. The rotation speed of the auger can be adjusted by selecting pulleys of different diameters. If this cannot be done, then an intermediate gearbox can be installed between the walk-behind tractor and the screw nozzle. It will reduce the speed to the desired frequency.
On the video you can see the work of a homemade snow blower:
A home-made snow blower with its parameters practically does not differ from factory-made analogues, but will cost the owner several times cheaper.
