Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to increase productivity and reliability by improving, (the exciting capacities of elastic spiral sectors 4, 5, 6. and 7. The screw of the harvester combine has a tubular shaft on which sectors 4 and 5 are fixed with the same winding direction and sectors 6 and 7 of the same winding, but opposite to the first. The sectors are set adjacent to each other and with the front ends shifted in the direction of rotation. The front end offset of each sector must be smaller than the size After that, the zone between adjacent sectors follows, which ensures the prevention of an excessive increase in exciting capacity and a sufficient effect on the transported mass of adjacent sectors 2 Cp f-ly, 2 l.

FIELD OF THE INVENTION The invention relates to agricultural machinery, namely, to designs of augers for harvesting parts of combine harvesters.

The purpose of the invention is to increase productivity and reliability by improving the gripping ability of elastic spiral sectors.

Figure 1 shows the auger, top view; Fig. 2 is a scan of the locations of elastic helical sectors on the surface of the tubular shaft.

The screw contains a tubular shaft 1 and in the area of the feeding mechanism 2 with fingers 3 is equipped with elastic spiral sectors 4 and 5 of the same winding direction and sectors 6 and 7 of the same but opposite first winding. Lengths 1 and 1.1. Respectively of sectors A and

7more lengths 1 and 14, respectively, sectors 5 and 6. Front ends

The 8 and 9 sectors 5 and 6 closest to the center 12 of the tubular shaft 1 relative to the front ends 10 and 11 are more distant from the center of the sectors 4 and 7 are shifted forward in the direction of rotation, respectively, by lengths 15 and 1. Each sector of the same winding is mounted adjacent to each other on length 1 and Ig. The angles of winding of helix lines are: ei 26, L 23 and 20, and the angle of elevation of the return helix should be close to.

The screw works in the following way.

The plant mass transported by the auger is picked up by the fingers 3 and sectors 4-7, which give it movement with a slowdown towards the center 12 of the tubular shaft 1. At the same time, sectors 4 and 5, as well as 6 and 7, act jointly due to their adjacent location. Sectors 5 and 6 separate part of the plant mass proactively in relation to the adjacent sectors 4 and 7, removing some of the load. Each sector 4 or 7 helps the adjacent 5 or 6 in the formation of the latest compacted and bonded mass, since the length of sectors 4 and 7 (1 and 1) is longer than the length of sectors 5 or 6 (1 and 1). The length of each sector corresponds to a progressively decreasing volume of transported vegetative mass, the movement of which slows down toward the free section of the tubular shaft 1. Thus, with a small screw aisle, sectors seize the vegetation better and move it more in a unit of time, which prevents failures at high yields

and improves device performance.
