Description

The working body of the sweeper.

The solution relates to machines for cleaning snow, ice and snow-ice and earthen rolls on the surface of roads and airfields.

In winter, with a sharp temperature drop and the removal of wet snow and slush on the surface of roads and airfields, ice and snow can form. Surface treatment with a sand-salt mixture or anti-icing reagents is not always effective. In addition, their use is limited to a narrow temperature range.

The following tools are known for removing snow and ice formations.

; The working body of the sweeper (ed. St. USSR No. 1636506, E 01 H 1/02, 1991), containing a cylindrical brush mounted on a lifting frame perpendicular to the longitudinal axis of the machine, a reflector consisting of separate curved elements placed inside the circle of rotation the periphery of the bristles of the brush and fixed to the indicated frame by means of a beam, parallel to the axis of rotation of the brush, with the front end sections of each element of the reflector located at an acute angle to the vertical longitudinal plane and to the horizontal plane, and the back - at an angle in the specified vertical plane parallel to the longitudinal axis of the machine, increasing efficiency is achieved by changing the direction of the flow of snow being thrown away, the reflector elements are mounted with the possibility of rotation around its longitudinal axis.

The disadvantage of this design is the inability to remove packaged snow and snow-ice formations, in addition, the inability to install on a standard machine without additional devices ..

as a prototype adopted the working body of a sweeper truck (RF patent No. 2094563, E 01 H 1/05, 1997), containing a drive, a frame in the form of crosses located at opposite ends of the drive shaft, with cylindrical brushes mounted on it associated with shaft and among themselves. On the axes of the cylindrical brushes, crushing disks are mounted for rotation, which allow crushing the compressed formations of the material on the road surface, while the disks of one axis are displaced relative to the disks of the neighboring axis by S t / p, where t is the step between the disks of one axis, n is the number of axes in the working body.

However, this working body has the following disadvantages:

- disks are a hard, non-deformable element, as a result, when cleaning uneven surfaces of cleaning, the effect is reduced;

-Do not remove a thin layer of ice;

- as the pile wears out, it is necessary to replace the disks, which is why a set of disks is necessary and, accordingly, time for their replacement.

The task at hand is the improvement of the working body of the sweeper.

The technical result is the ability to remove a thin layer of ice, rolls (both snow-ice and earth), which is important, especially for aerodrome coatings, additionally clean the surface, immediately remove the destruction product, and avoid deformation of the coating being cleaned.

This technical result is achieved by the fact that in the working body of the sweeper containing the drive, the shaft with sections of cylindrical brushes located on it in the form of a rim and rings with pile on it and elements for cutting the compacted layer of snow, ice or earth, the brushes are fastened in the section by the tightening grids passing the pile through the cells; mesh can be provided

notches and additional elements for cutting the compacted layer in the form of plates with teeth.

Varying the placement of cutting elements on sections, sections on the shaft, as well as the ability to quickly change, allows you to use the necessary combination, depending on the circumstances.

The proposed working body of a sweeper is shown in FIG. 1 is a general view, in FIG. 2 - section of the working body.

On the shaft 1, driven by a chain drive from a hydraulic motor mounted on the machine frame, sections 2 of cylindrical brushes in the form of a rim 3 and rings 4 mounted on it with a pile 5 are mounted. The brushes are fastened in section 2 by tightening grids 6, passing the pile 5 through the cells . The net 6 is an element for cutting off a compacted layer of snow, ice or earth. To increase the cutting effect, the mesh can be roughened, with notches, in addition, additional elements can be attached to it to cut the compacted layer in the form of plates 7 with teeth 8 (for example, in the form of a grater).

Any arrangement of plates on the section is possible. It is also possible to install any combination of sections on the shaft.

The device operates as follows.

The working body is mounted on a special car. When the car is moving, the shaft 1 with brushes is driven. By acting on the layer of snow, ice or earth formed on the road, mesh 6 destroys it. Effectively this process occurs if the mesh is made with notches, and even more so if it is equipped with plates 7 with teeth 8 (the thickness of the cut layer in the latter case is more than 5 mm). Simultaneously with the operation of the elements for cutting the compacted layer, a pile of 5 brushes works, removing the products of the destruction of the layer. Moreover, chips are removed throughout the area affected by the net 6. As the pile wears out

the mesh size can be reduced since It is easily adjustable by mounting.

When using plates, by analogy with “graters, snow enters the brush structure. Then falls out through the grid.

The elastic construction and the material of the plates (previously made of steel) does not destroy the asphalt concrete pavement.

By varying the size, number and location of the teeth on the plates and the plates themselves, it is possible to achieve removal of both small thicknesses and other (2-3 mm) snow rolls and ice and ice thickness; other up to 50 mm.

The brush design can be installed on the car airfield universal cleaning DE-224 (235) (Operating Instructions). Diameter 800-900 mm, rotational frequency; 530-680 rpm. On the DE-224 (235) machines, brushes 4 meters long are used; on ZIL-130 cars, the brush length is 2.5 meters. Therefore, in the manufacture of sections, to remove ice and rolled snow, it is advisable to make a width of 0.4 or 0.5 meters.

The advantages of brush design for removing ice and

- removes snow rolls and ice from any surface and at any temperature;

-does not require additional special devices when mounting on cars;

-the ability to use various combinations of plates and, accordingly, to increase the cleaning efficiency under various conditions;

-the possibility of compliance of the surfaces to be cleaned with all regulatory documents (i.e. a completely cleaned surface of ice, snow and other foreign objects); rolled snow.

- there is no destruction of the coating being cleaned.

- by varying the size, number and location of the teeth on the plates and the plates themselves, it is possible to achieve removal of both small overhangs (2-3 mm) of snow deposits and ice, and thick ice; another up to 50 mm.
