FIELD: agriculture; machine building.
SUBSTANCE: invention relates to agricultural machine building. Threshing and separating unit for harvesting leguminous crops includes a threshing drum with pests and a separating concave with elongated holes. Separating concave is made in the form of a cascade profile along a cylindrical generatrix. Cascade profile is made in the form of rectangular shelves with steps.
EFFECT: oblong holes are oriented with a long side along the concave symmetry axis, which ensures a reduction in the number of straw particles in the fine grain heap during separation.
