  • Combine harvester cleaning apparatus
    Patent number: 6672957
    Abstract: 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.
