Abstract
The axial flow rotary separator of a self-propelled combine employs dual side-by-side rotors sharing a common infeed opening. Finger-like crop engaging elements of the rotors are propelled in orbits both oblique and eccentric with respect to the separator casings. The rotors are counter rotating and a stream of threshed crop material is delivered towards the bite of the rotors so that it is carried through between the rotors and divided against an opposite floor of the infeed casing. The fingers are disposed so that, as the rotor rotates, the degree of engagement of each finger with the crop material stream varies and so that, while in its principal engagement with the material, each finger propels portions of the crop material stream generally spirally downstream.
