Abstract

1. CLEANLESS WORKING BODY OF THE DIGGER MACHINE, including a rotor fixed on the frame, made of a rim mounted on a shaft with traverses with cutting elements fixed on its periphery, and an ejector installed in the unloading zone, placed in a half rotor, of a slider, and so that, in order to increase the productivity of the working body by improving the conditions of unloading, the traverse with cutting elements are made in the form of -H-shaped brackets, the vertical shelves of which are fixed on the sides of the rim in chessboard order e, and horizontal shelves with cutting elements facing towards each other with the formation of a gap around the entire circumference of the rim. 2. The working body according to claim 1, which is based on the fact that the outer surface of the rim is formed by truncated cones facing (with large bases towards each other.

"Yes 1 The invention relates to the field of earth-moving machinery, more precisely, a shaft-free rotary tool with forced unloading for digging ditches and trenches in both thawed and frozen soils. . The purpose of the invention is to increase the productivity of the working body by improving the discharge conditions. FIG. 1 shows the shankless working body of the earthmoving machine; in fig. 2 is a general view of the rotor in an axonometric image on an enlarged scale; in fig. 3 shows a part of a rotor with a soil ejector; in FIG. 4 shows a section B-B in FIG. 3; in fig. 5 cut BB on. FIG. 3; in fig. 6 one of the soil throwers in cross section. Beskovsho rotor working body consists of the actual working body, performed in the form of a rotor 1 with cutting parts on the periphery and discharge device, representing a wedge-shaped extractor 2. The main carrier of the rotor 1 is a central rim 3, which is centered on the shaft 4. The rim can be placed a reducer or other drive device. On the outer surface of the rim, in the form, which is two connected between each other by large truncated cones, cutting parts 5 are fixed in a staggered manner, embodied in the form of L-shaped Scraps 6 having in front cross sections - so and three cutting corners and teeth 7. The vertical flanges of the bracket 6 are fixed on the lateral edges of the rim 3, the horizontal flanges with cantilever ends face each other. those. to its median plane with the formation of a gap due to the circumference of the rim. The bracket 8 that holds is placed in the gap. in the cavity of the rotor in a stationary state, the ejector 2, having the form of a wedge symmetrical with respect to the median plane of the rotor. Structurally, the ejector 2 can be made in the form of a sufficiently rigid sheet 8, which is the body of the support-bearing bracket and the arcuate plates 9 of strong spring steel attached to it on both sides. The bracket 8 is rigidly fixed on the frame 10 of the working body. The features of the operation of the proposed device are as follows. in the process of digging the trenches, the rotor 1 and the grinder 11 are driven into rotation, for example by hydromotors 12, and at the same time perform swinging movements in the horizontal plane. The soil developed by the teeth and rezushchih parts of the rotor falls into its cavity and is carried into the discharge zone, where through the side openings between the cutting parts is pushed out to the sides by the ejector. Further, the soil under its own weight (by trays or directly) falls on the ground throwers and is thrown into the dump. When digging trenches, the barrel body of the swing does not perform body movements.

Claims (2)

1. DUMP-FREE WORKING BODY OF THE EARTHING MACHINE, including a rotor mounted on the frame, made of a rim mounted on the shaft with traverses with cutting elements fixed on its periphery, and an ejector installed in the rotor cavity, located in the rotor cavity, on the heel The reason is that, in order to increase the productivity of the working body by improving the conditions of unloading, the traverses with cutting elements are made in the form of L-shaped staples, the vertical shelves of which are fixed on the sides of the rim in a checkerboard pattern, and the horizontal ntalnye shelves with cutting elements face each other to form a gap over the entire circumference of the rim. 2. The working body according to p. (. Characterized in that the outer surface of the rim is formed by truncated cones facing large bases towards each other to the rod. SU „1158695> 1 1158695 2.
