Description

The invention relates to railway transport, in particular to mechanisms for cleaning ballast of a railway track, in particular for cleaning crushed stone ballast, and can be used in other branches of the national economy, for example, to clean coal, ore and other fractions from weeds.

The aim of the invention is to improve the quality of cleaning rubble with different degrees of contamination while at the same time improving the reliability of the device by reducing mesh wear.

FIG. 1 shows a crushed stone device, general view; in fig. 2 - the same, top view.

The rubble-cleaning device contains a frame 1, to the upper part of which a fixture 2 is fixed rigidly for repeated cleaning of rubble, made in the form of a system and the tilts of the trusses 3, which are inclined to move the material, in which four and lower 5 rollers are placed at the top and bottom. The frame 1 also contains a drive roller 6 with a drive 7, a tension roller 8 and guide rollers 4 installed at the loading site of contaminated rubble equipped with a hopper 9. All the rollers are successively turned around by the cleaning grid 10, forming together with the system a slope 3 brackets with a spring-like surface.

To each arm 3, in the middle of the inclined sections of the grid 10, is attached a device for changing the curvature of the grid, made in the form of additional rollers 11, which are in contact with the upper surface of the cleaning grid 10, and the tension of the rollers 11 is adjusted. Above the rollers 4, placed in the upper part of the brackets 3, there are crushed stone flow distributors, made in the form of inclined plates 12 and installed rotatably around an axis located parallel to the surface of the cleaning grid 10..

The frame 1 with the lower part of the device 2 for the repeated cleaning of rubble is immersed in a container 13 filled with a liquid, for example water. The liquid level is chosen so that it is possible to visually monitor the operation of the device, i.e. the upper part of the brackets 3 and the partially cleaning mesh 10 are open.

In the lower part of the tank 13 under the device 2 reusable cleaning rubble mounted inclined tray 14, which

hangs over the cleaning conveyor 15, which may be, for example, scraper type. A lift 16 attached to the wall of the container 13 is.

The device works as follows.

The contaminated gravel ballast is fed to the loading part of the device in the bunker 9. Using the drive roller 6 from the drive 7, the cleaning grid 10 is conveyed in a direction from the loading bin 9 to the discharge part.

The flow of rubble, entering the surface of the cleaning grid 10, carried along by it, is advanced. At the same time, the weeds in the form of sand, earth and dust are sifted through the cells of the cleaning grid 10, along the inclined tray 14 they get onto the cleaning conveyor 15 and then with the help of the elevator 16 they are taken out. And crushed stone with residues of weed is applied to the next section of the tram-like surface, hitting previously with a stream distributor 12, rubble, which can change the direction of flow when it moves from one springboard to another. This m changes the length of the path and, consequently, the time that rubble is in the springboard. For example, when cleaning lightly contaminated rubble, it is advisable to reduce the residence time of rubble on the screen 10. When cleaning dirty rubble, the distributor 12 is turned down and the flow of rubble is directed to the lower part of the subsequent tramp line. As a result of strikes against the distributors 12 and falls from the spring-shaped areas, the rubble moves, and new parts of the rubble come into contact with the surface of the cleaning grid 10, which contributes to its better cleaning.

The reusable operation of bumps and drops of rubble contributes to the quality of its cleaning.

The elevation angle of the inclined sections of the cleaning grid 10 is smaller than the angle of repose of rubble during movement, however, this angle can be increased by using a tool for changing the curvature of the cleaning grid. This is necessary to increase the force acting on the weeds. The curvature adjustment device allows to improve the quality of cleaning in specific conditions when cleaning aggregate of increased contamination, while the performance of the device is not reduced.

Supplying the liquid 13 device also requires improving the quality of rubble cleaning. It is preferable to place a container under the last section. In this case, the bulk of the weeds has been previously removed and cleaning with a liquid is more efficient.
