Abstract
A self cleaning rotary screen of an agricultural combine is provided with a planar circular screen that is secured to an outwardly extending circular flange having an external groove and an internal groove. The screen is rotatably coupled to a pivotable door by a plurality of freely rotatable wheels which engage the internal groove of the flange. Also secured to the door are two freely rotatable idler sheaves located adjacent to the pivot axis of the door so that the centerpoint of the endless belt when coupled to the outer periphery of the sheaves forms a tangent axis that is substantially aligned with the pivot axis of the door. A driving sheave is operatively coupled to the propulsion system of the combine and is provided with a central rotational axis that intersects the tangent axis of the idler sheaves.
