ABSTRACT:
A clean grain and tailings conveying system for an agricultural combine, including a pan fixedly mounted beneath a lowermost sieve of a cleaning system. The pan includes a tailings receiving portion disposed below a peripheral edge portion of the sieve, for receiving tailings which fall downwardly from the edge portion during operation of the sieve, and a clean grain receiving portion disposed beneath the sieve for receiving clean grain which falls downwardly therethrough during the operation of the sieve. The pan includes at least one elongate collecting conveyor including a clean grain collecting portion which extends longitudinally through the clean grain receiving portion of the pan, and a tailings collecting portion which extends longitudinally through the tailings receiving portion, for separately receiving and collecting the clean grain and the tailings received by the pan, and conveying the clean grain and tailings to transfer conveyors that can also be part of the pan.
