FIELD: agricultural engineering, in particular, equipment utilized in threshers.
SUBSTANCE: threshing apparatus has movable upper and lower parts, and rolls with elastic rings of various diameters and widths. Each part of threshing apparatus is made in the form of endless elastic belt, which embraces driving and driven drums. Spring-loaded rolls positioned between drums of upper part abut against lower inner side of endless belt. Spring-loaded rolls positioned between drums of lower part are offset relative to rolls of upper part and are contacting inner surface of elastic belt. Elastic rings are located eccentrically on pins rigidly connected with one another. Lower endless belt is perforated and is equipped on its edges with sides recessed in vertical plane. Belt surface cleaning brush is located on inner side of lower endless belt, near driven drum. On outer side of lower endless belt, under driving drum there is device for feeding compressed air for removal of contaminants from perforations.
EFFECT: improved threshing quality without increase in dynamic loading applied to grain heap.
