Abstract
A combine side-shaking control system includes a sieve for separating crop material from other materials and configured to move in a fore-aft direction. At least one side-shaking assembly includes a mounting device attached to a combine chassis, a lower plate configured to rotate about a lower plate axis and an upper plate configured to (i) have an upper plate rotational motion and rotate responsive to the rotation of the lower plate and (ii) have an upper plate substantially linear motion in a substantially linear direction. A fixed arm is rotatably coupled to the upper plate and attached to the sieve. An actuation device is configured to rotate the lower plate about the lower plate axis. Responsive to the rotation of the upper plate, the sieve is controlled to move diagonal to the fore-aft direction in the substantially linear direction of the upper plate substantially linear motion.
