  • Front chaffer and cleaning fan
    Patent number: 6921330
    Abstract: A cleaning shoe of an agricultural combine is provided with a front chaffer located upstream from the main chaffer. The front chaffer has a closed upstream portion and an open downstream portion. The closed upstream portion is upwardly inclined and the open downstream portion is downwardly inclined. The front chaffer is oriented so that an air blast from the cleaning fan passes beneath the closed upstream portion and upwardly through the declined open downstream portion. The open downstream portion is provided with transversely extending louvers through which the air blast passes. The cleaning fan comprises a plurality of radially and transversely extending fan blades. Blade inserts forming air dams are located near each transverse end. The blade inserts are provided with apertures that limited the transverse air flow along the blades.
