Description

With known methods of harvesting grain crops by combines, most of the chaff — a valuable animal feed — is lost. In addition, the combine organs of the combines do not satisfactorily handle the separation of grain from the straw threshing of the first mass, part of the grain is removed from the thresher and is lost directly in the field.

The particular feature of the proposed thresher is that the output end of the threshing device deck is elongated, due to which the threshed product at high speed enters the conveyor perpendicular to its direction of movement and settles in between the slats of the conveyor that does not fall on the separating organs. Such a device facilitates and intensifies the work of the thresher's separating organs in extracting grain from straw.

FIG. 1 is a diagram of the thresher, side view; in fig. 2 - view of the thresher in the plan.

L1ashia consists of a sheet of no-p.: 1-framed pick 1, a beater 2, a drum 3 with freely swinging fingers, an upper deck 4, a pile conveyor, picker rollers made of triangular plates 6, a chain-slatted straw walker 7, screw 8 and chain scraper conveyor 9.

The baler is suspended on one side of a tractor or a self-propelled chassis using joints 10 and 11, while the other rests on the field wheel 12. The maschine mechanisms start the drive from the power take-off shaft through the gearbox, the propeller shaft and the belt 13.

The machine works according to its technological scheme.

The bread from the rollers is picked up with a pick-up finger and sent to the threshing device, in which the threshing drum is # 123792-2

It does not simultaneously separate functions. The threshed product moves in the direction shown in FIG. 1 with an arrow A, and hits the bottom and a slat of a conveyor moving perpendicularly to the direction of flight of the threshed product (along arrow B). At the same time, the grain settles in the spaces between the slats of the conveyor 5 and, not falling on the hammer-cutting organs (picker rollers), flows along with a small pile down into the screw 8.

Large straw from conveyor 5 is removed by picker rollers, removed from the Total flow, fed to the straw walker from 7 and then carried to the stubble on a separate roll or straw strawder, and grain, chaff and harvest, separated in the zone of picker rolls and straw walker 7, fed to the pups 8, and the conveyors 9 are loaded into trailer tare.

The grain heap is unloaded on the current, where its further refinement and grain extraction is carried out.

During the separation of the pile, the most valuable in the feed relation the waste of the floor and of the colony is cast into the litter and the ladle.

Subject invention

A continuous semi-mounted thresher with a top deck for picking and threshing cereals from the rolls formed by a series of headers, in which the raw grain, chaff and seed are sorted together, and the straw is fed to the stacker or stubble in a roll. By the fact that, in order to separate the grain from the threshed straw mass, before reaching it on the separating parts of the thresher, the output end of the deck of the threshing device is extended so that the threshed mass goes t at high speed onto the conveyor perpendicularly the direction of its movement and settles in the gaps between the transponder slats.
