SU1224375A1 - Crushed stone cleaning machine - Google Patents

Description

The invention relates to railway transport and can be used in machines for cleaning and crushed stone ballast without removing the track grid, as well as in other long-base machines, in which vertical movements of the frame are observed together with the working body during operation.

The aim of the invention is to increase productivity.

FIG. 1 shows a car, side view; in fig. 2 - the same, front view; in fig. 3 shows section A-A in FIG. one.

The machine contains front 1 and rear 2 pillars, which by means of hinges 3 are connected to a supporting frame 4, inside which the moving grate 5 of the crushed stone is skipped. The cutting knife 6 and bucket 7 are connected to spring-loaded sliders 8, mounted on the front support columns 1, with the possibility of movement relative to the latter. On the uprights of the lower part, stops 9 are fixedly mounted to limit the progress of the scoring path 6 and the rattles 7 downwards. On the front pillars 1 mounted movable fic12243752

With a fixed vertical position of the scoring knife and raking stones and the movement of the struts downward, the springs 11 are compressed. In this case, the reaction is determined only by the stiffness of the spring elements, which is chosen from the condition of eliminating the recess of the cutting knife when the working body is in operation and

25 possible reduction in resistance to movement of the knife. The spring travel is determined based on the elimination of the suppression of the supporting frame into the ballast and is 0.7-0.8 differences
