Corn thresher with a corn cleaning stage has an oscillating sieve box with coupled mechanisms to oscillate the sieve on two separate axes for effective separation of straw and chaff without clogging
The corn thresher has a cleaning system to separate corn from chopped straw material and chaff with a sieve box (2) coupled to an oscillating mechanism (11,12,12'16) to oscillate on one axis, and a further mechanism (14,15,15',17) for oscillation on another axis. The second mechanism (14,15,15',17) gives a clear vertical oscillation coupled with the one-axis oscillation from the first mechanism (11,12,12',16). The coupling between the oscillating mechanisms is a mechanical angular gearing.
