ABSTRACT:
An adjustment mechanism for opening size of sieve segments of the cleaning system of an agricultural combine disposed in end to end relation, which allows jointly adjusting the sieve sizes, or separate adjustment, and which allows easy and convenient removal and reinstallation of the sieve segments. The mechanism includes an adjusting element in connection with each of the sieve segments, which is movable in a predetermined manner for effecting adjustments in the opening size thereof. Connecting elements connect together the adjusting elements for joint adjustment, and are disconnectable to allow individual adjustment. The predetermined manner of movement can be, for instance, a simple rotational movement, and the connecting elements can include and elongate connecting element, such as a rod or tube which can extend over a substantial portion of the sieve segments.
