Abstract
The present invention comprises a novel roller for use on agricultural produce grading, sorting, cleaning and conveying equipment. The roller comprises a cylindrical hub having protruding fingers thereon which extend outward from the hub in a direction perpendicular to the hub axis and inclined away from the direction of rotation of the hub. The roller further comprises lateral support shoulders which allow the fingers to flex properly in the direction of rotation while providing increased rigidity in a lateral direction to improve grading opening uniformity and consistency. A concave shape on the outer surface of these lateral support shoulders also defines an improved grading opening shape which serves to increase grading uniformity as well. A smooth surface to the grading opening surfaces also prevent accumulation of mud and dirt in the critical grading opening area.
