摘要： A feed roll includes paddles mounted upright on a cylindrical surface of the roll and oriented parallel to its rotation axis, and V-shaped vanes in a central area of the feed roll. One or more paddles or paddle portions are located in the central area. The paddles or paddle portions may be located between the blades that define the V-shaped vanes, i.e. blades which extend between a top point at or near the tip of the V-shape and a base point at the base of the V-shape. Paddles may be present between the base points of one or more of the V-shaped vanes, and additional intermediate paddles may be located between the top points and the base points of the blades. The paddles or paddle portions in the central area enhance the capability of deflecting objects away from the threshing rotors downstream of the feed roll in a combine harvester.
