ABSTRACT:
An accelerator roll assembly for combines wherein one of the accelerator rolls comprises a conveyor roller having a conveyor belt extending therearound. The improved accelerator roll assembly is particularly adapted for use in a combine including a threshing assembly, straw walkers and a cleaning section and which further includes a belt type conveyor for conveying threshed material falling through the straw walkers to an opening to the cleaning section. An accelerator roll is mounted in front of and in closely spaced relation to a drive roller for the conveyor such that the accelerator roll and the conveyor belt passing around the conveyor drive roller cooperate to accelerate, in a downward direction, threshed material passing therebetween. The threshed material is directed through a rearwardly directed stream of air of sufficient velocity to entrain and carry rearward the lighter chaff and stalk particles while the heavier kernels of grain pass downward through the stream of air to the grain pan.
