Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery industry and can be used in devices for threshing corn cobs. The purpose of the invention is to reduce seed damage and increase self-cleaning from threshing residues. The corn threshing device for corn cobs includes a frame 1 with a threshing drum 2 having a cylindrical 3 with pins and a conical 4 with scourge parts, a casing 5 of similar shape with a hopper 6, an actuator 7, a shaft 8 and a mechanism 9 for its axial movement, perforated deck 10, the sieve mill 11 and the protective device 12, made in the form of a cylinder, covering the end of the cylindrical part 3 of the drum 2 and two blades mounted on the cylinder with overlapping gap between it and the casing 5 and tilted to the conical part 4 of the drum 2. Threshing quality when the variety changes, the humidity of the cobs is provided by adjusting the gap between the deck 10 and the conical part 4 of the drum 2 due to its axial movement along the axis of the shaft 8 by the mechanism 9. When the drum 2 moves forward between its face and the casing 5, a gap is formed which, to prevent the cobs and The maize grain overlaps with a cylinder, and the blades remove the cobs and grain from the gap between the cylinder and the casing 5 and direct them to the threshing zone. 3 il.

2, having a cylindrical 3 with pins and a conical 4 with a whip part, a casing 5 of the same shape with a hopper 6, an actuator 7, a shaft 8 and its axial movement mechanism 9, a perforated deck 10, a cutting mill 11 and a protective device 12 made in the form of a cylinder covering the end of the cylindrical part 3 of the drum 2 and two blades mounted on the cylinder with overlapping gap between it and the casing 5 and the tip to the conical part 4 of the drum 2. The quality of threshing changes the invention The invention relates to agricultural machinery and it can be used in devices for threshing the corn cobs.

The purpose of the invention is to reduce seed damage and increase self-cleaning from threshing residues.

FIG. 1-threshing device for corn cobs, general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - section bb pa fig. 2

The corn threshing device for corn cobs contains a frame 1 with a threshing drum 2 having a cylindrical 3 with sleeves and a conical 4 with scourge parts, a casing 5 of similar shape with a hopper 6, a drive 7, a shaft 8 and a mechanism 9 for its axial movement, perforated deck 10, Rescent mill 11 and a protective device 12, made in the form of a cylinder 13, covering the end of the cylindrical part 3 of the drum 2 and two blades 14, mounted on the cylinder 13 with overlapping gap between it and the casing 5 and inclined to the conical part 4 of the drum 2.

Threshing device for corn cobs works as follows.

Corn cobs from the hopper 6 are evenly fed to the cylindrical part of the casing 5, where they are caught by the rods of the cylindrical part 3 of the drum 2 and are moved to the conical part 4 to the area affected by the scourge. Seeds isolated from the cobs are sifted through the holes of deck 10 and enter the bottom sieve, the moisture of the leaves is provided by adjusting the gap between the deck 10 and the conical part 4 of the drum 2 due to its axial movement along the axis of the shaft 8 by the mechanism 9. When the drum 2 moves forward between its end and casing 5 form a gap, which, to prevent the ears from entering and the corn grain, is covered by a cylinder, and the blades remove the ears and grain from the gap between the cylinder and the casing 5 and direct them to the threshing zone. 3 il.

of the mill 11, are cleaned of impurities and fed for post-harvest processing and

storage. The rods descend onto the upper grille of the mill 11 and then out of the installation. The quality of threshing when changing the variety, humidity of cobs or other indicators is provided by adjusting the gap between the deck 10 and the conical part 4 of the drum 2 due to its axial movement by the mechanism 9 along the axis of the shaft 8. Poi moving the drum 2 forward between its end face and the casing 5 creates a gap to prevent the corn and corn grain from overlapping, the cylinder 13 overlaps, and the blades 14 remove the corn and grain from the gap between the cylinder 13 and the casing 5 and direct them to the threshing zone.
