ABSTRACT:
A grain combine with an improved threshing cage surface achieves greater separation efficiency without increasing the length of the threshing section. The invention utilizes rings mounted to the interior surface of a perforated screen. The rings are transversely secured to a helical vane which is used to guide the crop material rearwardly through the threshing section. The rings interrupt the grain sliding rearward by forcing the grain to bounce over the rings. Since the grain does not penetrate the straw when it bounces over the rings, this invention creates greater separation by decreasing the velocity of the grain so that it may pass more easily through the perforations in the screen. The rings also agitate the grain that is mixed with the straw to allow the grain to penetrate outward toward the perforations in the screen.
