FIELD: agricultural engineering. SUBSTANCE: separator has casing 1 with separating surface 2 and rotor 3 positioned within casing 1. Of at least two pivotally connected parallelograms positioned within rotor 3, one parallelogram has cranks 20 and 22 and connecting rod 24 and another parallelogram has cranks 21 and 23 and connecting rod 25. Parallelograms are kinematically connected one with the other. Fingers 26 are arranged in rows on connecting rods of parallelograms and oriented toward periphery in such a way that angle between tangent to finger working surface and rotor body in the direction of displacement of finger along slot at intersection point is at least equal to right angle at each given moment. When employed in combination with tangential threshing unit, two pivotally connected parallelograms are positioned in planes parallel one with the other in equally spaced relation to rotor axis of rotation. Pair of cranks of these parallelograms have opposite direction of rotation and connecting rods with fingers are positioned in symmetry with axis of rotation of rotor each given moment. Axes of rotation of cranks of different parallelograms are axially aligned in pairs and intersect axis of rotation of rotor. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 2 cl, 2 dwg
