This invention relates to snow machines.

The purpose of the invention is to increase efficiency by expanding technological capabilities.

FIG. 1 shows the working body of the rotor snowplow, side view; in fig. 2 is a view A of FIG. one; in fig. 3 is a view B in FIG. 2; in fig. 4 shows a modification of the tool with a vertical axis of rotation of the rotor, side view; in fig. 5 shows a section B-B in FIG. 3; in fig. 6 is a view of FIG. four; in fig. 7 is a section d-d in fig. 3

The working member comprises a frame 1 with a platform on which feeders consisting of two parts 2 and 3 are mounted, and a rotor 4 installed in the casing 5 with an outlet nozzle 6. The rotor 4 is connected through a drive shaft 7 with an adjustable drive motor 8. Parts 2 and 3 of the feeders are made in the form of hollow cylinders, installed in parallel in the holder 9 with the possibility of rotation of one part relative to the other by means of a romotrra 10. Spiral blades are fixed on the inner surface of the cylinders. 11 with the right and left windings. The length of the cylindrical part is 3-5 sizes of its internal diameter. Bearings 12 and 13 are installed between the inner annular surfaces of the yoke 9 and the outer surfaces of the cylinders 2 and 3. The faces 9 are closed with plates 14 and 15 in which there are holes for the cylinders on which cylindrical gears 16 and 17 are mounted in the middle part interacting with a common pinion gear 18, pos.3. The working organ according to claim 1, characterized in that the ratio of the length of the cylindrical part of the feeders to its internal diameter is from 3 to 5.

4. Working body according to claim 1, characterized in that it is provided with

 compressor, communicated with nozzles that are installed between the feeders.

on the shaft 19 of the hydraulic motor 10. On the shaft 19 of the hydraulic motor 10 and gear 18 is mounted a compressor 20, which is connected by flexible pipelines

with nozzles 21 mounted on the plate 14 of the holder 9, between the cylinders on their front parts there are fastened torres in the form of hollow cones 22 and 23 attached by small bases to the cylinders. Cutting elements 24 are installed at the free ends of the sockets for interacting with the snow. The cutting elements 24 may be provided in the form of teeth or

cutting inserts cutters. The design of the cutting elements 24 is selected depending on the snow to be cleaned. The rear parts of the cylinders are mounted in front of the rotor 4. The yoke 9

it is supplied with the basis 25 with the folded shoulders bent down. Under the base 25 on the frame 1 there is an annular guide 26, between which the base 25 and the annular guide 26

rolling bodies 27 are installed. On base 25, a shaft 28 of a drive mechanism 29 is fixed to change the direction of rotation of the cylinders. The drive mechanism 29 in the form of an adjustable hydraulic motor mounted on the frame 1.

8 working and transport provisions of the working body base 25 of the clip

9 connects to ring guide 26 by means of control locks 30, which may be you

They are filled in the form of electromagnetic devices with movable cores 31, which interact with 1 m with holes 32 placed around the circumference of the annular guide 26.

The rotor 4 is provided with an additional guide casing 33, and the frame 1

equipped with lugs 34 for suspending the implement to the base chassis and skis or wheels to reduce loads on the base chassis frame (not shown). The hydraulic motors 8, 10 and 29 are connected to the hydraulic system of the base chassis, and the latches 30, through the controls, to the source of electrical energy, the generator of the base chassis. The working body may comprise a rotor 4 with a vertical shaft arrangement 7. At the same time, a cone grid 35, made of antifriction synthetic material, is mounted on the casing 5.

The working body is lowered onto the area to be cleaned from snow, the hydraulic motors 8 and 10 of the rotor 4 and the feeder are turned on, with the drive mechanism 29 and the latches 30 disconnected. When you turn on the hydraulic motor 10, the compressor 20 supplies compressed air to the nozzles 21.

The feeder speed is set depending on the thickness of the snow layer to be removed and the speed of the mixing of the base chassis, and the rotor 4 turns of speed depending on the required snow throw distance taking into account the capacity of the feeder and the rotor 4 at a given snow thickness and the speed of the base chassis.

When the base chassis moves, the cutting elements 24 of the sockets 22 and 23 and squeezing the air flowing out of the nozzles loosen the snow, which, gradually pouring over the blade m 11, moves along the cylinders and then flows through an additional

Right, the 1st case 33 and the loading window into the rotor 4. From the rotor 4, the snow is ejected through the exhaust pipe 6.

In the working body with a vertical axis 7 of the rotor 4, the loosened snow, having passed the cylinders, falls under the action of its own weight through the conical grid 35 into the receiving opening of the rotor 4. At the same time, the conical grid 35 excludes 4 large objects from entering the rotor.

During operation, there may be cases when large items get into the feeder, which causes overloading of the feeder. In this case, a safety valve is triggered in the control circuit of the hydraulic motor 10. The operator reverses the direction of rotation of the feeder cylinders to the opposite, which ensures the unloading of large objects from them.

When cleaning hard-to-reach places, such as the street strip, they turn on the fixture, rys 30, change the direction of the feeder to the side of the shaft of the cleaned strip in the range of 30-45 °, turn off the latches 30, and then set the set turns of the feeder and the rotor 4. Partly but bypasses the rotor 4 and falls to the left or right side of the working body. After cleaning the strip of the lotus, the second passage is carried out, in which the feeder is installed in the main position with the loading of snow into the vehicle, or is thrown out of the green, lawn plantations.
