Abstract: An auger assembly that has three individual augers that function cooperatively to transport silage within a silo. Specifically, the auger assembly is used to manipulate silage during the loading and unloading of a silo. The first and third augers have the same flighting and rotate in the same direction. The second auger is positioned between the first and third augers and rotates in the opposite direction and has flighting that is the opposite of the flighting of the first and third augers. The individual augers rotate so that silage is moved along parallel with the longitudinal axes of the augers. The design of the auger assembly allows the assembly to transition from a loading to an unloading configuration by electronically reversing the direction of rotation of the individual augers without mechanically altering the auger assembly configuration.

Abstract: An anti-pollution grain drying apparatus comprising: a grain drying bin having a perforated floor through which hot air is blown upwardly for drying purposes; a rotary sweep mounted in the bin for counter-clockwise (CCW) sweep movement along the floor, during which its lag side continuously deposits wet grain as it rotates over the floor to form thereon a circular layer extending about 345.degree. clockwise (CW) from the lag side of the sweep to the lead side thereof while its lead side continuously retrieves dried grain from the adjacent end of said circular layer on the floor; and an anti-pollution suction system operative to remove air-borne dust, from the dried grain being retrieved along the lead side of the sweep, and direct it into outside equipment which separates the air and dust, captures the dust and discharges the clean air into the ambient atmosphere.

Abstract: A reversible rotary sweep has a single railless trough-less contemporaneously reversible 16" OD horizontal long auger and a depending holeformer composed of a 191/2" OD depending short auger and a surrounding 21" ID concentric sleeve. In unloading, a substantial portion of the unloading stream of silage normally flows radially inward along opposite sides of a vertical "unloading plane", extending tangentially to the unloading side of the auger. The upper end portion of the depending sleeve presents a silage overflow edge, which extends slightly below the horizontal bottom tangential plane of the long auger. Horizontally, the overflow edge is long enough to extend from the inner side edge of the unloading stream through the unloading plane to the outer side edge of the stream. As a consequence, the discharging silage, on both sides of said unloading plane, is free to cascade into the sleeve in a free-flowing substantially unobstructed condition.
