Abstract
A conveyor for a combine harvester includes a chain and a sprocket. The sprocket includes an annular body defining an axis of rotation, two opposing sides, an outer perimeter extending between the two opposing sides, and gear teeth disposed on the outer perimeter. A bottom land extends between valleys of adjacent gear teeth. A single continuous edge is defined between two gear teeth at one of the adjacent sides. The bottom land includes (i) a central plateau portion, (ii) a first sloping surface extending from one edge of the central plateau portion to the single continuous edge at one of the two opposing sides, and (iii) a second sloping surface extending from the opposite edge of the central plateau portion to the single continuous edge at the other of the two opposing sides. The sloping surfaces either limit or prevent the accumulation of material thereon.
