Description

The invention relates to agricultural machinery, in particular to designs of combine harvesters equipped with picker attachments for threshing corn.

The aim of the invention is to reduce the wear of the threshing device.

FIG. 1 shows a combine harvester with an extension for corn harvesting; in fig. 2 - - the last beater with bar; bilami; in fig. 3 - the same, option, complete; in fig. 4 - stone grill.

The harvester contains- picker box 1, including inclined-mounted thrusters 2, cutting machine 3, mounted under rollers 2, chopper 4 of leaf-stalk mass, located behind rollers 2, transverse 5 cobs and inclined chamber 6 with a coil conveyor made in form of horizontal and horizontal beaters 7 with elastic blades 8. Between the blades 8 of the last beater 7, convex beats 9 are installed, and under the beater 7 there is a stop 10 attached to the bottom 11 of the inclined chamber 6. Beat 9 can be Neno as a series of horizontal bars

12 or in the form of a floppy oval surface. The largest gap between the bil 9 and the stop 10 should be 3-5 mm smaller than the diameter of the average corn cob.

The ball 9 is displaced along the blades 8 of the beater 7 in the direction opposite to the direction of rotation of the beater 7. Behind the last beater 7 is located a threshing device containing a receiving beater 13, a threshing drum 14 and a concave 15. Between the beater 7 and the receiving beater

13 is installed a funnel 16, is closed by a lattice 17c slots 18, located

at an angle. A funnel 16 and a threshing device are installed on the nod board sleep 19. Next, the separating devices 20 are located.

Combine harvester with prefix for harvesting corn works as follows.

Moving along the rows of cucumber crops, the combine harvester 2 prefixes 1 passes the stalks, the cob section. Stems

they are cut by the cutting unit 3, then crushed by the chopper 4 and fed by it into the vehicle or scattered across the field. The cobs, separated from the stems by the cobbing rollers 2, are fed by the transverse screw 5 to the inclined chamber 6 and here by elastic blades 8 horizontal beaters 7 are transported to the receiving bit 13, which feeds them into the gap between the threshing drum 14 and the side bar 15. Pops

After the last horizontal beater 7 of the inclined chamber 6, the cobs are subjected to preliminary partial destruction (the cobs are deformed in the gap between the beams 9 of the last beater 7 and the stop 10). Since the beater 9 is displaced along the blades 8 of the beater 7 in the direction opposite to the direction of its rotation, the pulling capacity of the beater 7 increases (tightening the cob into the gap between bil 9 and the stop 10) and its deforming ability. The partially destroyed cobs are fed by the receiving beater 13 to the threshing, and the grain separated from the cobs in the inclined chamber 6 is fed through the slots 18 of the grille 17 and the funnel 16 to the threshing device to the ground board 19, to which the grain that has been steamed is fed. through the concave 15 threshing device. After cleaning, all the grain accumulates in the combine hopper.
