Description

The invention relates to agricultural machinery and can be used in the construction of a corn harvesting device.

The purpose of the invention is to reduce the size and increase the separation ability.

FIG. 1 shows a diagram of a corn harvesting unit; in fig. 2 shows section A-A in FIG. one; in fig. 3 - installation of a grain cleaning device on elastic elements; in fig. 4 — node I in FIG. 3; in fig. 5 is a view B in FIG. 3

The selection corn-harvesting unit contains a reversible tractor 1 with two-sided control, above which is mounted a picker 2, having a pressing device 3, rollers 4 and a conveyor 5. A coil threshing device 6 is installed on the side of the tractor 1 and a pitched board 7. On the opposite side of the tractor 1 there is a threshing device 8, which has a drum 9, blades 10 enclosed in a casing 11 and a duct 12. Under the threshing device 8 there is a grain-cleaning device 13, which has a sieve 14 fixed to a hinge 15 and mounted on elastic elements 16. The sieve 14 is provided with orienting grain

/ 1- / 1

protrusions 17, made in the form of hemispheres. Under the sieve 14 is a container 18 for the grain.

A tractor 19 is placed above tractor 1, which is connected to cattle board 20 on one side, and with elastic screen 21 on the other. There is a channel 22 for grain between screen 21 and threshing device 8. When the unit is in operation, the longitudinal conveyor 6 feeds the cobs on the pitched board 7

in the hatch 2, where under the action of the pressure device 3 and the rollers 4 are cleaned from wrapping leaves that fall on the conveyor 5. Then the wrapping leaves fall on the chute board 20 and out of the aggregate, and the broken grain from the cobs, when they are cleaned, is separated through the conveyor 5 to the casing 19 and through the channel 22 enters the sieve 14. The cobs enter the threshing device 8 and after threshing, the pile gets

on the sieve 14. The grain by the projections 17 is guided into the holes of the sieve 14, and then enters the container 18. Large parts of the rods move along the protrusions 17 and, when stopped, are released by turning the sieve 14, and the smaller ones are carried out through the channel 12

outside the unit.

The application of the invention provides a reduction in size and allows for improved grain permeability.
