Abstract: An automotive combine has a frame adapted to move in a travel direction along the ground, a front housing pivotal on the frame, a cutter on the front housing for cutting standing crop, and a main thresher on the front housing having a front intake and a rear output for taking in the cut standing crop at the intake, threshing it, and ejecting it at the output as a chaff/grain stream and a separate chaff stream. A pair of separate conveyors on the frame each have an intake at the rear output for receiving the chaff/grain stream and a respective output for ejecting respective portions of the chaff/grain stream. One of the conveyor outputs is vertically spaced above the other conveyor output. An upper sieve at the one conveyor output and a separate lower sieve at the other conveyor output receive the respective portions of the chaff/grain stream and separate kernels from chaff therein.

Abstract: An automotive combine has a frame adapted to move in a travel direction along the ground, a front housing pivotal on the frame, and a cutter releasably mounted on the front housing for cutting standing crop. A main thresher on the pivotal front housing has a front input and a rear outlet for taking in the cut standing crop at the input, threshing it, and outputting it at the outlet as a kernel-rich stream and a separate chaff stream. A blower conveyor on the frame has an intake receiving the kernel-rich stream and an output provided with a conduit for blowing the kernel-rich stream from the outlet. A grain bin is mounted on the machine frame and a sieve on the frame underneath the outlet of the blower separates kernels from chaff in the kernel-rich stream and delivers the kernels to the grain bin while depositing the chaff on the ground outside the combine.
