In an axial flow rotary separator, each radially extending finger-like crop-engaging element of the rotor is individually and obliquely journaled on a fixed eccentric shaft. Push bars spaced 90 degrees apart rotate about the axis of the separator to drive the fingers so that the finger tips describe a circular path eccentric to the separator casing and inclined to its axis. The plane of rotation of the fingers and the speed of rotation of the rotor are chosen so that the fingers maintain the crop material in an annular mat in contact with the inside wall of the casing and propel it spirally downstream. Finger element bearing housings are split for convenient assembly and repair.

An axial flow rotary separator for receiving, processing and forwarding crop material comprising: a tubular, generally cylindrical casing having an inside surface and a central longitudinal axis; an elongated support extending within the casing and offset from the longitudinal axis of the casing; a plurality of crop material engaging elements, each element including a single elongated finger; means for axially spacing the crop-engaging elements on the support and means for journalling the elements individually on the support so that each element is rotatable about the support in a selected plane of rotation oblique to the longitudinal axis of the casing, the planes of all adjacent elements of the plurality being parallel one to another; first drive means extending within the casing for engaging some of the crop-engaging elements and drivably rotating them in a first array about the support, said drive means engaging each element at a first point of contact; and second drive means for engaging others of the crop-engaging elements and drivably rotating them in a second array about the support, said second drive means engaging each element of said second array at a second point of contact, said first and second points of contact normally being spaced apart circumferentially.
