  • Patent number: 9301451
    Abstract: A grain bag unloading device which is compact and reduces farm operating expenses by unloading grain from an elongated grain bag to a position adjacent to the grain bag such that the grain may be further moved using an existing grain elevator or the like. The device includes a spool coupled to a frame. An actuator rotates the spool to pull a grain bag onto the spool. Wheels facilitate movement of the frame as the grain bag is pulled onto the spool. A gathering mechanism urges grain in the grain bag towards a collection area. A first end of a collector is operationally coupled to the gathering mechanism such that the collector is dispenses the grain from the collection area.
