Abstract:
A combine harvester comprising:a main frame; a threshing and separating arrangement mounted to said main frame and including: a generally cylindrical chamber having a generally longitudinal axis and comprising a separating concave assembly; and a rotor assembly mounted for rotation in said chamber and comprising a generally cylindrical rotor body with a separating section associated with said separating concave assembly; and said separating section of said rotor assembly comprising a plurality of longitudinal elements having a leading, generally longitudinally arranged crop engaging face said longitudinal elements are arranged in an axially staggered pattern and having longitudinal wear plates which are removably attached to generally longitudinally arranged supports affixed to said rotor body, wherein said longitudinal wear plates and said longitudinal supports have an outwardly and rearwardly inclined front edge and have a leading face which is inclined backwards with respect to the normal rotation of the rotor, wherein said separating section further is provided with a plurality of transverse elements having a generally transversely arranged crop engaging edge said transverse elements are arranged in an axially staggered pattern and have a transverse wear plate which are removably attached to generally transverse supports affixed to said rotor body, wherein said transverse wear plate and said transverse support have a leading edge which is inclined backwards with respect to the normal rotation of the rotor and at least some of said transverse elements have a leading portion adjacent the rear end of a leading face of one of said longitudinal elements and at least some of said transverse elements have a trailing portion ending adjacent a leading face of the longitudinal element, wherein the outer edges of said transverse wear plates are profiled such that their leading portions extend above their middle portions.
