FIELD: agriculture.

SUBSTANCE: invention refers to the sphere of agricultural engineering industry. The combine comprises a harvesting part with an output window, an intermediate beater and an inclined chamber with transporting elements in the form of serially installed beaters. An auger of narrowing type is installed in front of the output window with a finger mechanism with turns of opposite direction, ends of which are arranged in front of the output window. Each beater of the inclined chamber is arranged in the form of a driving shaft, the section of which is shaped as the right polyhedron, where spacing collars and discs are serially arranged with alternation. Axis of the disc symmetry is displaced from the axis of the driving shaft rotation. A threshing-transporting element is mounted on the peripheral section of each disc. On the first beater the specified element is arranged from a rod of round section and is oval-shaped with opened ends. Its rounded section and ends are fixed in slots at the end of disc. At the second beater the threshing-transporting element of round section has zigzag shape. Its ends and the middle section are mounted in slots at the end of disc. At the third beater the threshing-transporting element of round section has ellipse shape. Its rounded section is mounted in the disc hole, and open ends are mounted in slots at the disc end.
