摘要： A threshing unit is arranged in a concentrically spaced relation within a perforated rotatable grain separating cylinder. An elongated axially fluted impeller located below the threshing unit and within the separating cylinder accelerates the speed of travel of the threshed material to substantially the peripheral speed of the separating cylinder to reduce grain cracking and fracturing. The grain is centrifugally separated through the separating cylinder for removal by a clean grain auger located therebelow and the chaff is discharged by air flowing axially between the threshing unit and the separating cylinder. Tailings from the threshing unit are moved rearwardly along the inner peripheral surface of the separating cylinder for pickup and return to the threshing unit. A pair of oppositely arranged axially extended nozzle units direct concentrated blasts of air inwardly of the separating cylinder to lift the chaff and grain from the inner peripheral surface thereof whereby to continuously clean the cylinder perforations for clean grain travel therethrough.

摘要： An axial flow combine having a crop harvesting header including a feeder for cutting a crop and feeding it rearwardly into a threshing and separating mechanism. The mechanism includes a casing for receiving the crop material and a rotor within the casing for threshing and separating grain from the crop material. The rotor has a central drive shaft driven through a gear case behind the rotor. The gear case is partially enclosed within a cover having a smooth exterior surface. The end of the rotor is configured in a smooth exterior surface which is complementary to the surface of the cover to inhibit collection of chaff about the drive shaft. Impeller blades are secured on the rotor for creating an air flow directing crop material away from the drive shaft to prevent crop material wrapping about the shaft or accumulating in the drive system.

摘要： A self-propelled axial flow combine having a crop harvesting header for supplying crop material to a longitudinally oriented rotor power-rotated within a generally cylindrical casing. The casing includes a grate through which crop material is impelled at high speed by the rotor. The combine includes a grain cleaning system having a chaffer sieve reciprocably mounted to receive crop material from the grate for sifting the material as a part of the cleaning process. Crop sensors are mounted on the chaffer sieve to sense material flow from the grate. In addition, crop sensors are mounted at the rear of the chaffer sieve for sensing crop losses from the sieve.

摘要： In an axial flow combine, an improved inlet transition area for changing the flow of crop materials from a linear ribbon-like flow through the feeder to an arcuate ribbon-like flow about the flighting of the inlet end of the rotor to a helical sleeve flow between the rotor and rotor casing while at the same time injecting crop materials in all portions of the flighting. A sloping ramp extends upwardly and rearwardly from the feeder to an elliptical intersection with the rotor casing. A pair of oppositely disposed sidewalls in generally perpendicular relation to the ramp extend from the feeder and converge about the inlet end of the rotor at an upper portion of the rotor casing. Another wall between the sidewalls, oppositely disposed from the ramp, encloses the inlet transition area. A rotary beater disposed between the sidewalls and in close proximity to the inlet end of the rotor rotates at a higher tangential velocity than the feeder to direct and accelerate the crop materials upwardly and rearwardly along the sloped ramp and the converging sidewalls to entrain the crop materials about all portions of the flighting of the rotor in an arcuate ribbon-like manner. All of the surfaces of the inlet transition area are either planar or cylindrical for ease and economy of manufacture and fabrication. Related methods are disclosed.

摘要： A combine harvester comprising at least one generally cylindrical crop handling unit having tandem threshing and separating sections through which material is advanced along a generally helical path. A conveyor is provided for receiving crop material from a forwardly positioned crop header and delivering it axially into the cylindrical unit. During operation, grain is separated from the crop material and discharged through concaves and grates in the threshing and separating sections, respectively, onto a grain pan which in turn deposits it on cleaning sieves located rearwardly of the grain pan. The clean grain is elevated to a storage tank mounted on the combine while the residue is conveyed rearwardly and expelled onto the field. The grate in the separating section is cylindrical in configuration and comprises a plurality of generally transverse members retained by spaced longitudinal rub bars defining a configuration of apertures permitting discharge of grain over most or all of the circumferential surface of the cylindrical unit. One or more of the transverse members have at least one slightly askew section to assist advancement of crop material along its helical path in the separating section of the combine. A portion of the separation grate extends into the threshing section.

摘要： A combine of the axial flow type having an axially extending power driven rotor which coacts with a concave complementary in shape to that of the rotor to thresh a wide variety of agricultural crop material. The concave comprises a plurality of longitudinal bars that are spaced transversely and a first row of curved wires extend through said bars adjacent the upper edges thereof and are spaced even distances in a longitudinal direction to form passages for threshed crop material. A second row of wires extend through a row of holes in said bars below said first row of wires. The second row of wires is spaced more closely than the wires of the first row to form pockets which receive said threshed crop material and remove the same from contact by said rotor to prevent damage to the threshed material and also provide more aggressive threshing of the material.
