Description

The invention relates to machines for the winter maintenance of roads.

A rotor snowplow working tool is known, comprising a fixed body, a screw feeder installed perpendicular to the direction of movement of the snow blower, and a transporting rotor with blades located in the middle part of the body, a throwing device mounted on the back side of the screw feeder and communicated with it through a through window

A disadvantage of the known working body is its low efficiency due to the high energy consumption for moving and ejecting snow due to the mutually perpendicular arrangement of the rotational planes of the transport rotor and propelling apparatus and the complexity of the design of the planetary gearbox.

Known working body snow blower, consisting of two or more rotary

throwers, on the continuation of the axes of rotation of which the knives are located, and additional screws, take advantage of the rotor throwers of the rotary throwers and parallel screws in the direction of the snow plow.

The disadvantage of a known working body is the complexity of its design, as well as the increase in energy consumption and snow throwing, as well as thrusters and screw knives are coaxially and have the same angular rotation rate.

The closest to the invention (prototype) is a working snow thrower, in which the rotary thrower and belt mills are installed coaxially, while the ends of the belts with the rotary thrower are equipped with profiled blades, and on the side walls of the casing of the rotary thrower are located 5 5 holes.

This design allows to increase the efficiency of the snow blower tool, since the profiled blades tell the snow particles the trajectory of movement, co-directed with the plane of rotation of the rotary thrower.

However, due to the fact that the band mills and the rotary thrower are installed with bob, the speed detector of the snow fed to the rotary thrower is angled to the plane of rotation of the latter, which leads to additional energy costs for moving and throwing snow.

The purpose of the invention is to increase efficiency by reducing the energy consumption for moving and throwing snow.

This Znl is achieved by the fact that the axis of rotation of the screw feeder and the rotary thrower are parallel to each other, the rotational planes of the transporting blades and the rotary thrower coincide, and the screw feeder is made in the form of a truncated cone, on the larger base of which the transporting blades are placed, and its body is possibility of rotation around the vertical axis.

FIG. 1 schematically shows the working body of the snow blower; in fig. 2 shows section A-A in FIG. one.

The working body of the snow plow contains a screw feeder 1 with belt mills, a rotary thrower 2, a housing 3 with an inlet 4.

The screw feeder 1 is made in the form of a truncated cone, on the larger basis of which the tape cutters are equipped with transporting vanes 5, opposite to which on the back side of the housing 3 having side walls 6 and 7, a rotary thrower 2 is installed in the casing 8 with the nozzle 9. The axis of rotation the screw feeder 1 and the rotary thrower 2 are parallel, and the planes of rotation of the transport blades 5 and the rotary thrower 2 coincide. The side wall 6 is made in the form of a wedge-shaped opening, and the case 3 of the screw feeder 1 is installed with the possibility of rotation around a vertical axis at an angle a to the direction of movement of the snowplow.

During the operation of the snow plow, the screw feeder 1 develops and moves the snow along the body 3 to the transport blades 5, which give its particles an initial peripheral speed in the plane of rotation of the rotary thrower 2, the blades of which pick up the snow and accelerate

it up to the required rate of release through the pipe 9.

Forcing the supply of snow from the screw feeder 1 by means of transporting blades 5 to the plane of rotation of the rotary thrower 2 provides a reduction in energy consumption for snow emission.

At the same time, the execution of the screw feeder 1 in the form of a truncated cone, on the larger basis of which transporting blades 5 are placed, will allow a smooth increase in the peripheral speed of the particles of snow being developed as it moves along the body 3 to the rotary thrower 2, while the maximum speed is reached in the plane rotation of the latter, which allows to reduce the energy consumption for driving the screw feeder 1.

In addition, the possibility of turning the body 3 around the vertical axis at an angle a to the direction of movement of the snowplow helps reduce its drag resistance and prevents the formation of

prism dragging before the working body An additional advantage of this design is to reduce the distance of snow emission to the side of the road or when loading it into transport, since

rotary thrower 2 is shifted to the edge of the cleaned lane

In general, the proposed design of the snow blower tool allows to increase productivity and reduce

energy intensity of his work
