Description

The invention relates to the construction, in particular to machines and equipment maintenance, construction processing of roads, airfields.

Known machine for the destruction of snow-ice formations, containing the base chassis, the wheels of which are made in the form of rollers, which are attached to destroy the teeth ΐ]. .

The disadvantage of this machine is that the chassis is rigidly connected to the wheels by means of axles, as a result of which shock impulses arising at the contact of the wheels with the snow-ice formation are transmitted to the whole machine, which leads to its rapid wear and destruction.

It is also known a device for the destruction of snow-ice formations containing a base chassis, a frame hinged on it, on which a working body mounted on an axis, made in the form of a skating rink with destructive teeth fixed on its surface £ 2 ^.

Due to the hinge frame with a working body on the base chassis, the famous machine is free from the first drawbacks, since the shock arising from the splitting of snow and ice

2

impulses are largely extinguished in the frame - working tool system. However, when splitting ice and compacted snow, some of the reactive loads

’Is transmitted to the frame, which reduces the efficiency of the working body, and consequently, its effectiveness in the impact of the teeth with the face.

^ιυ The purpose of the invention is to increase the efficiency of the device by intensifying the process of destruction, as well as fixing the roller in the axial direction.

15

This goal is achieved by the fact that in. a device for breaking snow-ice formations containing

2θ base chassis, a frame hinged on it, on which a working body is mounted on an axis, made in the form of a roller with destructive teeth fixed on its surface,

__ the roller is hollow, and the device. equipped with pneumatic rollers to interact with the inner surface of the roller, associated with the frame and located in its cavity, and at least one pneumatic roller is driven.

In addition, in the device on the inner surface of the fixed annular stops for pneumatic.

FIG. 1 shows the proposed device for the destruction of snow-ice formations; in fig. 2 shows a section 5A-A in FIG. one; in fig. 3 - rybochiy body, general view; in fig. 4 is one of the possible embodiments of the plate, with the destructive tool ^ in FIG. 5 - destructive tool, general view.

The device for destruction of snow-icy formations contains a base chassis 1, on which frame 2 is hinged. The walls 3 are rigidly fixed on the frame, on which pneumatic rollers 5 are mounted by means of axles 4.

The roller is supported on the pneumatic rollers, armed with a destructive tool 7 "At least one of the pneumatic rollers 2 (5 is driven by the drive mechanism 8 fixed on the roller axis. To prevent the roller from moving on the pneumatic rollers in the axial direction, the last 25 limited by ring stops 9, fixed on the inner surface of the roller.

In the transport position the frame 2 is transferred through the mechanism 10. For biasing __ cleaved away at the PA ¹³⁰ IU fixed blade 11.

The device works as follows.

Lowering the working body into position. The mechanism 8 is turned on with water, which drives the pneumatic rollers 5, frictionally connected to the roller, and rotates it counterclockwise or in the opposite direction of rotation of the base wheels. 40

Work tool 7 is embedded in ice or snow and destroys it. At the same time, the dump of the '8 sets aside the destroyed ice, clearing the coating from the ice fragments, therefore the base 45 chassis 1 runs over. the surface cleared of ice and, moving along the cleared road, continues to chip the ice or destroys the frozen ground in a continuous process. 50

In the process of interaction destructive tool with destructible

the environment arising reactive loads are extinguished in the body of the roller, not spreading to the frame due to isolation of the roller by means of pneumatic rollers. At the same time, all the energy of the instruments of raskhoh is poured out for destruction, its efficiency of use increases. Due to the elastic connection between the frame and the roller improves the ability to copy irregularities of the road profile, which improves the quality of cleaning the road surface.

The technical and economic effect from the use of the invention lies in the fact that the working body’s impact on the ice-covered road is improved, which ultimately results in a high performance and quality of road surface cleaning ζ ^_
