Cleaning system for a combine

摘要

A cleaning system for a combine including a fan and reciprocal sieves mounted within a housing of the combine. The sieves include a series of transversely extending slats which are selectively adjustable to allow clean grain to pass therethrough. A plurality of transversely adjacent baffles extend in a fore-and-aft direction along substantially the entire length of and for a relatively short distance above an upper distance of the sieves. The baffles have a cumulative effect of inhibiting a disproportionate granular accumulation of granular material adjacent the downhill side of the sieves when the harvesting apparatus is tilted during slope harvesting. Each of the baffles are movable conjointly with and in response to adjustment of the slats of the sieves.
