Spring-mounted rasp bar shellerIowa State University Patents
AbstractA spring-mounted rasp bar sheller for com is described herein. The sheller comprises a plurality of spaced apart rasp bars mounted on a combine or sheller cylinder. Each of the rasp bars has studs secured thereto which extend therefrom through the cylinder backing plates. Springs are mounted on the studs behind the backing plates for yieldably urging the rasp bar inwardly towards the backing plate. Centrifugal force causes the rasp bar to move out radially towards the concave as the cylinder is rotated. During shelling, impact forces on the rasp bars deflect them radially inwardly. Filler plates are also disclosed for preventing the com from becoming lodged between the backing plate and the rasp bars.
