Description

The invention relates to mining machinery, in particular to working bodies of combines for mining, and is an improvement of the device according to the author. St. No. 989082.

The purpose of the invention is to reduce the labor intensity of manufacturing and installation and dismantling works when changing the workplace of the combine.

Fig, 1 shows a working body, a general view; in fig. 2 shows section A-A in FIG. 1, the working body at the beginning of the assembly; in fig. 3 - the same, the working body at the end of the assembly.

The working body has a drive sleeve 1, mounted on the output shaft 2 of the drive combine (not shown), faceplate 3 and the rays 4. On the side surface of the sleeve 1 are the protrusions and open grooves b. On beams 4 open grooves are made in under the protrusions and the bushings 1 and protrusions g under the grooves b. In addition, concentric grooves are made on the beams 4 and the bushing, which form annular cavities for the rusks 5. On the end surface of the bushing 1 there are stops l, defining the angular positions of the beams 4 on the bushing. On the beams 4 and the sleeve 1, there are made common holes for them under the cylindrical plugs 6. In the planner 3 there are recesses, and in the cracks 5 there are holes in the tabs 6. On the beams and the plate there are scrubs 7.

The assembly of the implement is as follows.

Lerazborna part of the combine is mounted once on the horizon after the lowering of the component parts by lifting vessels. At the same time, the component parts of the working body are mounted - sleeve 1 and plate 3. The disassembled part of the combine is equipped with trolleys and can be delivered to the place after it is finished (assembly line along the track. After the delivery of the combine into the prepared launch chamber, the assembly of the working body is completed. For this, The spacers and hydraulic cylinders for feeding the plate 3 extend for a distance ensuring the plant 4 of the beam 4 between the sleeve 1 and the faceplate 3. The beams 4 are brought to the sleeve 1 by means of load-handling means to the stops so that the protrusions press into slots, respectively, in b. The concentric grooves d in beams 4 and e on sleeve 1 form annular cavities into which crackers 5 are brought. At the same time, the holes in beams 4 are matched, in drive sleeve 1 and in crackers x 5 After that, cylindrical keys 6 are installed in them. To facilitate the assembly, the holes in the crackers x 5 are made somewhat larger than the diameter of the key 6.

After installation of the keys 6 by the feed cylinders, slider 3 is slid onto the sleeve 1 with the beams 4 so that the protruding ends of the keys 6 are inserted into the corresponding recesses in the face plate. Disassembly of the beams 4 is performed in about

WORKING BODY OF THE COMBINING COMBINE by ed. St. No. 989082, characterized in that, in order to reduce the complexity of manufacturing and installation and dismantling, it is equipped with crackers with key holes, and the sleeve is made with a flange located on the side surface in its lower part, while on the adjacent surfaces of the sleeve and beams grooves for rusks are made, and the protrusions on the beams are located on the lower side of the beam parallel to the axis of the working body, are directed to the side opposite the face, and are installed in the annular groove of the sleeve made in its flange.
