Abstract:

An apparatus and method for unloading a grain or particulate matter large capacity storage bin. The apparatus includes a bin with a cylindrical side wall. A relatively large opening is provided in the side wall. A box frame is generally vertically installed to the inside of the bin and intersects the opening in the side of the bin. A plurality of inlets into the box frame are spaced apart along the inner most side of the box frame. The box frame defines a channel that intersects with the opening in the bin. The plurality of smaller openings control the flow of particulate matter into the channel to allow control but fast unloading of the bin by gravity.
