COMBINE CROP FEEDING SYSTEM Abstract of the Disclosure A combine has a feeding system, for conveying crop material from a harvesting unit to the infeed rotor of a longitudinal axial flow rotary crop processing unit, including a feeder house employing a pair of augers, mounted side by side in an enclosed housing, and contrarotating at a relatively high speed. The augers are cantilevered from a bulkhead at the inlet end of the feeder house and do not make contact with the housing. The housing cross section does not conform to the cylindrical surfaces swept by the augers and there is also space between the augers themselves so that heterogeneous material can be conveyed within the housing on all sides of the augers. Housing shape and clearances are designed so that there is a minimum of dead space in the housing and, with some assistance from fixed strippers, mounted inside the housing parallel to the axes of the augers, material is conveyed generally linearly at a speed nearly equal to the equivalent axial speed of the auger flighting. A transi- tion housing, between the feeder house and infeed rotor casing is shaped to minimize dead space at the point of transfer from the feeder house augers to the infeed rotor, so that the moving elements (augers and rotor) do not lose control of the material being conveyed. A feeder beater is used at the feeder house throat to strip material from the harvesting unit cross auger and assist in accelerating it in the feeder house.
