FIELD: agricultural engineering, in particular, equipment used in cereal harvesting machines.
SUBSTANCE: beater has support with curved blades having convexity oriented outside and being inclined backward. Blades are fixed on support. There is projection on peripheral ends of blades, said projection being formed as rotating cylinder. Slot between projection and cylinder proper is defined by partial withdrawal of cylinder above blade contour. Beaters successively smooth spikes from their base to apex, said spike being transferred from one beater to another. Spike is curved on curved surface of blade, and grains of outer row obtain pulse for throwing thereof. Curvature of projection is greater than curvature of blade proper, therefore spike is bent in still steeper manner and grains are thrown away from spike by centrifugal force.
EFFECT: increased threshing efficiency and reduced specific consumption of power for threshing.
