through the wall of the rotor housing. During rotation of the rotor housing the tines projecting to the greatest amount at the bottom of the rotor housing are moved longitudinally in the direction of conveying the crop material from the threshing assembly to the straw walkers. The tines tear apart the mat of straw increasing in the separation of kernels still retained in the straw. To increase the rate of separation the tines are either fastened to the axle through wobble plates or the axle is constantly moved axially by means of an eccentric-drive motor. In this way the free ends of the tines also move in the axial direction of the rotor and further tear apart the straw mat.
DE-OS-22 35 061 discloses a combine in which anwith movable or flexible tines supported on a rotor which perform undershot conveying of the crop material. The tines are flexible, but always extend with their full length into the crop. It is also proposed that several such separators be arranged one after another.
According to DE-C3-42 09 020 a separator drum operating as an overhead conveyor is inserted between a threshing assembly and the straw walkers which catches the threshed crop coming from the threshing assembly and decelerates it so that kernels contained in the mass of the crop are deposited on the surface of the separator drum while the straw is passed along to the straw walkers.
DE-A1-41 27 118 shows a combine with straw walkers and a crop processing arrangement located above the walkers, which performs undershot
