Abstract
A grain bin loading and unloading system has a vertical auger located in the center of the bin, the vertical auger being in communication with a horizontal auger disposed beneath the floor of the bin. The novel sweep auger drive has a double row sprocket rotatably mounted about the center auger column. The sweep auger proper is rotatably mounted about the center column and is driven at its inner end by a gearbox which is also rotatably mounted. The input shaft of the gearbox extends vertically downwardly and has a sprocket located thereon. That sprocket is connected to one row of the double row sprocket located about the center column such that when the double row sprocket is driven the sweep auger assembly will rotate about the center column as well as be driven so as to transport the grain to be unloaded radially inwardly. In doing so, the input shaft of the sweep auger gearbox is driven in such a manner that the motion of the sprocket is a planetary-like motion wherein the sprocket both rotates and revolves about the center column.
