Abstract:
A combine harvester having a feeder housing, a thresher and a separation unit including a rotor driven by a shaft and arranged in a rotor housing, said thresher and separation unit having a feed end and a discharge end, means for mounting said thresher and separation unit at an angle of at least about 30Â° from a horizontal plane, and a transfer mechanism located in the region of the intersection of the feeder housing and the feed end of the thresher and the separation unit, the transfer mechanism including:a plurality of auger blades rotatably connected with the rotor at the feed end; a rotating element having feeding bars extending crosswise of the rotor, the rotating element having an axis of rotation perpendicular to the axis of the rotor and being located in the feeder housing and above the feed end of the rotor, and means for rotating the rotating element in a direction so that it feeds unthreshed harvested crops from underneath the rotating element's axis of rotation to above the axis of the rotor and onto the rotor: a transition housing connecting the feeder housing and the rotor housing and having a plurality of interior edges forming a feeding opening through the transition housing wherein the interior edge of the transition housing that forms the bottom of the feeding opening is longer than the interior edge that forms the top of the feeding opening, and wherein said transition housing projects up to the width of the feeder housing and has a concave bend to accommodate the circumference of the rotating element; and wherein the interior edge of the transition housing forming the bottom of the feeding opening is provided with at least three floors, each of said floors being at a different height.
