Patent ID: 8282453

Claim:
A combine comprising: a cleaning system having a grain bed having a front end, a rear end, and two sides, wherein the two sides are parallel to each other from across a width of the grain bed and wherein the length of the grain bed extends from the front end to the rear end of the grain bed; a cleaning conveying system for processing a crop material by moving the crop material between the front end and the rear end of the grain bed; a tailings distribution system that receives crop material previously processed in the cleaning system and redistributes the previously processed crop material back to the cleaning system; one or more sensors placed at the grain bed for monitoring crop material distribution in the grain bed; a control system for receiving a signal from the one or more sensors; and a tailings distribution adjustment mechanism for adjusting the crop material redistribution in response to the sensed crop material distribution in the cleaning system, wherein the tailings distribution adjustment mechanism comprises an adjustable deflector, the adjustable deflector is alterable about a pivot connection the tailing system, the pivot connection is pivotal about an axis substantially perpendicular to the grain bed, further wherein when the one or more sensors detects an uneven crop material distribution in the grain bed, the control system adjusts the tailings distribution adjustment mechanism about the pivot connection to alter the angle of the adjustable deflector to redistribute the crop material evenly on the grain bed.
