METHOD FOR THRASHING CEREAL CROPS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2020 - IPC A01F12/18 A01F7/00 

FIELD: agriculture; machine building.

SUBSTANCE: group of inventions relates to agricultural machine building and can be used for thrashing cereal crops. Method comprising combination of impact, wiping and combing non-monotonic effects of single-drum threshing device on threshed culture, consists in the fact that the exposures are carried out in cycles of ten exposures, in each of which two high-impact impacts are accompanied by each two low-impact impacts, and the third high-impact impact is accompanied by three low-level impact actions. Device for threshing grain crops comprises drum 1 with ten tooth working elements, located on three of them streamlined planks and located under drum deck 2. At that, two tooth working elements with streamlined planks 6 are accompanied by each two tooth-like working elements without streamlined planks 6, and the third tooth-shaped working element with streamlined bar 6 is accompanied by three tooth-like working elements without streamlined planks 6.

EFFECT: group of inventions makes it possible to carry out two-phase threshing with single-drum threshing device at increase of combine throughput capacity, reduction of losses of grain and its damage.
