Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to the design of a corn combine, its inclined chamber. The inclined chamber contains sidewalls 3, the bottom and a conveyor located above it, made in the form of successively placed tines. The latter are made of two sections installed with overlapping each other relative to the longitudinal axis of the inclined chamber. Thus, in the overlap zone, i.e. In the zone of the largest cob, twice the number of beater blades is involved. This ensures uniform loading of the threshing drum of the combine with axial feeding of cobs to the tines, 3 sludge.

The invention relates to agricultural machinery, in particular to inclined chambers of combines, and can be used in machines for harvesting corn for grain.

The purpose of the invention is to improve the uniformity of loading of the threshing drum when feeding the cobs to the beaters in the direction from the sides to the longitudinal axis of the combine.

FIG. 1 shows the proposed tilting camera, top view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - camera, sectional view in axonometry.

The inclined chamber comprises a housing 1 with a bottom 2 and sidewalls 3. Above the bottom 2 there is a conveyor made in the form of sequentially installed rotating tines 4-8 with elastic blades 9. Each taper is made of two sections 10 and 11, which are turned one relative to the other on 90 ° angle. In this case, the diametrically opposite blades of each section of the beater and the opposite section of the adjacent beater are installed mutually perpendicular. The ends of sections 10 and 11 relative to the longitudinal axis of the inclined chamber are installed with each other overlapping.

Inclined chamber corn harvester works as follows.

The cobs, for example, by opposite windings of the auger (not shown) move from the sidewalls to the longitudinal axis of the combine and then enter the inclined chamber to the tines 4-8, which, interacting with the bottom 2, move the cobs to the exit of the inclined chamber and serve to the threshing drum (not shown). Blade 9 of one of the sections of the beater pushes a certain part of the cobs captured by it along the bottom 2 and delivers the cobs to the opposite section of the adjacent beater, the blades of which are perpendicular to the blades of the previous section of the beater. By the time the cobs approach the second beater section, the blades of the latter turn and advance the cobs to the next beater. The overlapping of the ends of the sections eliminates the winding of impurities of the pile of cobs on the beater shaft, while in the overlapping zone of the ends of the sections the cobs are more intensively transported, since during one turn of the beater, twice the number of blades takes part in the work, which ensures a uniform loading of the threshing drum, as the double number the beater blades are involved in the area of the largest cob of cobs - in the center of the inclined chamber.
