Abstract
A cleaning apparatus for a combine harvester is disclosed wherein the grain pan and chaffer sieve are mounted in a subframe pivotally supported by a shaker shoe for a laterally tilting movement about a fore-and-aft extending axis. The shaker shoe is connected to an eccentric drive to effect a generally fore-and-aft shaking action to convey threshed grain thereon in a rearward direction. The pivotal movement of the subframe relative to the shaker shoe is accomplished through the use of a hydraulic cylinder interconnecting the shaker shoe and the subframe to permit a lateral leveling of the grain pan and chaffer sieve when the combine is operated under sidehill conditions. An inclinometer is utilized to control the flow of hydraulic fluid to the hydraulic cylinder to permit the subframe to be leveled in response to a sensing of a non-horizontal transverse inclination by the inclinometer.
