FIELD: agricultural engineering. SUBSTANCE: threshing apparatus has feeding and threshing-separating device. Upper wavy surface of threshing and separating device is defined by flexible belt and drive drums arranged along edges. Drums are eccentrically mounted on shafts. At least two additional elliptical drums within belt contour in lower part are put on shafts with eccentricity so as to form running wave on belt together with drive drums. Deck with openings is arranged under belt at variable gap. Deck is equipped with reversing drive. Threshing gap may be regulated. Apparatus allows unconventional crops to be threshed for seed growing. EFFECT: wider operational capabilities and improved quality of threshed material. 9 cl, 13 dwg
