SU931888A1 - Crushed stone cleaning device - Google Patents

Description

This invention relates to railway transport. A crushed stone device is known, containing a frame, a cutting knife mounted on it, breaker sheets and a driving endless transport and cleaning body in the form of a metal grid f. The disadvantages of the known device are the lack of precise direction of movement of the contaminants during cleaning, road rubble and low efficiency of the collection of the released contaminants. The purpose of the invention is to increase the productivity and quality of the operation of the rubble-cleaning device. To achieve this goal, the rubble cleaning device is equipped with screw conveyors fixed to the frame and dividing partitions located between them, the length of which is less than the length of the screw conveyors. H. At the same time the screw conveyors are laid one above the other. In addition, the length of the screw surface of the upper conveyor is greater than the length of the underlying screw connector. FIG. 1 shows a rubble cleaning device, front view; in fig. 2 - that is, side view; Fig. However, when converting a crushed stone device from the working position to the transport position. On the frame T mounted cutting knife 2, fencing sheets 3 and the driving endless transporting and cleaning body in the form of a metal grid and. On the frame 5 of the roller battery is fixed, the frame of the device, on which the screw conveyors 6,7 and 8 are attached. The screw conveyors are mounted on. bearings 9, 10 and .P. rolling. Separating partitions 12 are located between the screw conveyors,

6 and 8 have right-handed winding of the screw surface, and the conveyor

7- left side. Drive screw conveyors made through the open gear 13 and the belt 14 transmission by means of a hydraulic motor 15.

The length of the partitions is less than the length of the screw conveyors, which are located one above the other.

The device works as follows.

. The road rubble from the cutting knife 2 enters the infinite grid k.B of the working chamber of the grid k and the contaminants are ejected (indicated by an arrow in FIG. 2). The contaminants fall on the rotating screw surfaces located at the height of the slave, whose chambers, and are fascinated by the latter along or at some angle to the axis of movement of the rubble cleaning machine (axis of the railway track). The movement of the contaminants is indicated by the arrow in FIG. 1. Next, the contaminants fall out of the window 16 of each section of the device, and then fall on the curb and stack along the path. At the same time, the axial speed of movement of contaminants is equal to or greater than the translational speed of movement of its organ - an infinite grid, and, consequently, of the machine itself. The transfer of the device from the working position to the transport one is carried out by means of hydraulic cylinders 17. The cleaned / crushed stone in the area of the tension rollers 18 changes direction and falls on the baffle plates I and then is placed in the prism.
