Abstract
An infeed mechanism for a rotary cleaning device for cleaning threshed grain in combine harvesters is disclosed wherein an infeed auger includes a pair of helical flights terminating in a pair of radially extending distributing paddles. The infeed auger is mounted forwardly of a rotatable cleaning cylinder with the distributing paddles being positioned within the axial opening through the cleaning cylinder to discharge threshed grain radially outwardly into individual cleaning shoes. A grain pan is provided within each cleaning shoe to receive the threshed grain discharged from the distributing paddles, each cleaning shoe being operable to reciprocatably move in a generally fore-and-aft direction to convey grain received on the grain pans rearwardly onto sieves also mounted within the cleaning shoes. The infeed mechanism is also provided with an upwardly extending infeed chute that is flared outwardly from top to bottom to serve as a conduit for the infeed of threshed grain into the infeed auger.
