The grain holding bin of a combine harvester can be rapidly unloaded either on-the-go or at a standstill by an inclined unloading conveyor having its intake end at a low point in the bin adjacent the far side of the bin. The unloading conveyor extends gradually upwardly and outwardly in a straight line from its intake end to a point above and beyond the opposite side of the bin to provide a straight, unrestricted run for grain being unloaded without twists, turns and significant breaks in auger flighting. The outer end of the unloading conveyor can be pivoted back into a rearwardly extending transport position about a simple generally upright pivot hinge. The driving connection between inner and outer portions of the interior auger of the unloading conveyor is automatically re-established as the outer section of the unloading conveyor is returned to its unloading position, notwithstanding the fact that the unsupported inner end of the outer auger section drops slightly out of concentricity with its surrounding tubular housing when the outer conveyor section is in its transport position.

The arcuate processing assembly of a combine harvester may be pivotally adjusted generally radially toward or away from a rotary processing device to adjust the operating clearance between the periphery of the rotary device and the assembly. Simultaneously with such adjustment of the assembly as a whole, in a compound pivoting action one arcuate member of the assembly is also pivoted relative to the other arcuate member to properly reshape the threshing region for the adjusted running clearance.

The rotary beater has a number of untwisted, flat, feeding plate segments angularly disposed about its periphery. The plates are arranged in a left-hand group and a right-hand group so oriented that they converge the crop material centrally as they feed and accelerate the crop material rearwardly toward and through the inlet of an axial flow threshing rotor assembly. The feeding segments of each group are arranged in diametrically opposed sets containing at least one segment each, and the sets of one group are offset circumferentially 90&deg; from the sets of the other group. Each segment has a hardened crop-engaging face, and the segments are all detachably bolted to the drum of the beater to facilitate removal and replacement when worn or damaged.

The cleaning apparatus of a combine harvester has an oscillating sieve assembly and an oscillating pan assembly beneath the sieve assembly. The sieve assembly comprises a pair of superimposed sieves, both of which are mounted on the same frame for oscillation in unison and always in the same direction. The pan assembly comprises a clean grain pan and a tailings return pan both mounted on a common frame that is separate from the frame of the sieve assembly so that the pans oscillate separately from the sieves. The sieve and pan assemblies are mounted and driven in such a manner that the feed stroke of each assembly is in the same direction as its direction of conveyance, so as to maximize their ability to deliver materials in the intended direction. The clean grain pan, and optionally also the tailings return pan, is corrugated along its upper feeding surface with the corrugations inclined forwardly in the conveying direction so as to maximize the feeding action while minimizing retrograde movement of the materials thereon.
