FIELD: agriculture.

SUBSTANCE: invention relates to agriculture and can be used to harvest the seeds of leguminous plants. Finish threshing device comprises a housing 1 of a tubular section, a combined rotor 4 and a deck 8. The housing 1 has a receiving neck 2 and a discharging window 3. Combined rotor 4 is provided with intake screw part 5, threshing part 6 of beater type and throwing out blade part 7. Deck 8 is located inside the housing 1 and has two rubbing surfaces with ridges and a wrap angle of 180° each. The rubbing surfaces are located diametrically opposed to each other. Each rubbing surface consists of three sections of ridges of a rectangular cross section placed sequentially one after another. The ridges of one of the sections are placed along the axis of the housing, and the ridges of the adjacent section are located at an angle 45° to the axis of the housing. At the entrance to finish threshing device the screw guides 13 are located, installed in 120° on wrap angle. Due to a different location of the ridges in adjacent sections of the deck 8 the processed pile is exposed to a diverse impact.

EFFECT: intensification of threshing process.
