FIELD: agricultural engineering. SUBSTANCE: inclined chamber has casing and feeding beater with combing members made in the form of plates of different height. Threshing drums arranged inside inclined chamber casing are provided with working members formed as loop-shaped teeth. Grain discharge device is positioned under grid. Beater combing members of greater height are positioned for engagement with teeth of neighboring threshing drum. Mown cereal heap is gripped by plates of feeding beater and fed to first threshing drum, which moves cereal heap along separating grid. Engagement of drum teeth with fingers of separating grid results in threshing of full-weight grains, which are delivered to discharge device. In subsequent threshing drum, grain heap is further threshed. Cereal heap comprising difficult-to-separate grains is fed by cutting beater into threshing unit of grain combine. Inclined chamber provides for intensified threshing process and effective separation of full-weight grains. EFFECT: simplified construction and increased efficiency. 6 cl, 1 dwg |
