Abstract

A husker roll for use in an agricultural product separating apparatus, such as a corn husking apparatus. The husker roll includes a plurality of axially extending ridges or flights which protrude radially from a cylindrical base segment of the roll. The cylindrical base segment may have a circular or elliptical cross-section. The axially extending flights may extend substantially straight or in a helical fashion along the length of the roll. The flights are spaced apart around the circumference of the base segment so as to define grooves between the flights, wherein the circumferential width of the grooves is larger than the circumferential width of the flights themselves. Preferably, the circumferential width of the grooves between the flights is approximately three times the circumferential width of the base portion of the flights. The husker rolls are mounted adjacent to each other in an agricultural product separating apparatus and rotated such that husks or other materials to be removed from an agricultural product are grasped between the flights of adjacent rolls and pulled from the product as the rolls are rotated. The large groove formed between the flights on the rolls allows an ear of corn or other agricultural product to ride lower on the rolls, more closely to the point where the flights engage between the rolls, thereby improving the ability of the rolls to grasp and remove material from the product. The husker rolls may be provided with a helical recess formed therein which extends across the axially extending flights, and a continuous rib extending radially from and axially along the husker roll, parallel to the flights, to improve the ability of the rolls to remove stalks or other large debris from a separating apparatus employing the rolls.
