FIELD: agriculture mechanical engineering. SUBSTANCE: working member has casing secured to a support provided with a pin. Working grooves, which alternate with support areas, are made on curved surface of the casing. Rear projection is coupled with the support and an inclined support for rigidity. Each groove has threshing edge and transporting area. In operation bottom part of panicle enters space between rollers at first and then as the panicle move along the rollers, the top part of the panicle enters the space. EFFECT: enhanced efficiency. 2 cl, 4 dwg
