FIELD: agricultural engineering, in particular, equipment used in threshing devices of grain combines. ^ SUBSTANCE: combine has header, grinder, and threshing device. Grinder is disposed between header and threshing device consisting of axial threshing drums and decks. Whip holders incorporating whips, and device for forced displacement of threshed mass are fixed on outer surfaces of threshing drums. Threshing drums are mounted within decks made in the form of rotating pipes. Front parts of threshing drums are disposed under grinder and are open at their top end. Centrifugal compressors with air intake are located in front parts of internal cavities of pipes and nozzle units are mounted in lateral walls of pipes. ^ EFFECT: increased efficiency in grain threshing and increased extent of grain cleaning. ^ 3 cl, 2 dwg
