GRAIN COMBINE HARVESTER Russian patent published in 2013 - IPC A01F7/06 A01F12/18 A01F12/44 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machinery industry and may be used in grain combine harvesters. The combine comprises two axial separating rotors, a receiving beater 18 and a scraping device. The separating rotors are located longitudinally parallel to each other inside the corresponding housings 19 and serve to separate grain from the straw. The receiving beater 18 rotates around the transverse axis and is located in front of the separating rotors. The guide blades 34 on the receiving beater 18 direct the flow of the agricultural crop from the central zone of the beater 18 and to the corresponding flows of agricultural crop, connected to two rotors. Above the beater 18 a scraping device is mounted, comprising fixed blades. The agricultural crop material which is fed back from the upper part of the beater 18, is scraped freely from the beater 18 and is directed outwards by the fixed blades, so that removed material is re-fed under the beater 18 outside the central zone.

EFFECT: combine design eliminates winding of the agricultural crop on the beater 18 and jamming.
