Abstract

An axial flow combine receives a crop material through a radial feeder opening at one axial end of a foraminous cage in which a coaxial rotor rotates. The cage is disposed within a processor housing and threshed material passing through the radial openings in the cage is accelerated downwardly to the cleaning section by accelerator rolls at the bottom of the processor housing. A portion of the space within the processor housing above the feeder opening is closed off in a unique manner to prevent threshed material from entering the area directly above the feeder opening and to divert threshed material passing through perforations in the cage near the closed-off space axially inward so it slides and falls downward alongside the feeder housing to the accelerator rolls. An overfeed auger is eliminated and a portion of the cage above the feeder opening is solid rather than perforated thus reducing the initial cost of the combine and maintenance expenses without significant reduction in harvesting capacity.
