Abstract
Abstract A grain cleaner including, in series, feeder chutes, an inlet manifold, vibrating apparatus, an outlet manifold and vertically extending outlet chutes. The feeder chutes are designed to have a specific minimum cross-sectional area ratio and they serve as conduits between grain elevators or scalpers and the inlet manifolds. The inlet manifold includes both an opening at the top for receiving a mixture of grain and foreign matter and side walls converging downwardly toward outlets. The outlets are located at one side of the inlet manifold near the lower end, each one being constructed to feed a stream of the mixture to one of a plurality of superposed screening decks. The mixture flowing through the outlets may be individually regulated by gates disposed therein to give uniform flows to each deck. Each deck includes a screen superposed over a pan. Whole grains are retained above the screen; fines, consisting of foreign matter, broken grains, and undersized grains, fall through the pores of the screen onto the pan. A vibrator is operatively assembled to shake the box and its contents at an acceleration of at least 3.4 times that of gravity and to exert a throw on the fines which is adequate to cause them to strike the underside of the screen and dislodge any material blinding any of the openings. The outlet manifold includes two outlets from each deck. One outlet is disposed to receive the grain which is retained on the screen. The other outlet is disposed to receive the fines on the pan. A passage in the outlet manifold adjoins each of the outlets and baffles are provided therein to horizontally deflect the grain or fines into different vertically extending outlet chutes. Below the outlet manifold, the outlet chutes are structured to laterally deflect the grain in one direction and the fines in another direction whereby all the grain will empty into a single duct and the fines will empty into another single duct.
