Abstract:

A bale unroller for unrolling cylindrical bales of hay. A boxlike container has a side door for insertion of a bale of hay onto an elevated and inclined floor. A plurality of angle irons extends transversely across a floor and are connected at ends by chains which are in turn driven by sprockets. As the sprockets are driven, the angle irons slidably move along the floor to impart rotative movement to the bale. A plurality of rollers, horizontally disposed above the floor at the discharge end of the unroller, limit forward movement of the bale. A pair of wheels, which are pivotally supported by a framework, urge the bale forward to keep it in contact with the rollers. The sheet of hay, which is removed from the bale, is fed from the unroller by a lower roller and by a paddle conveyor. Methods of unrolling a cylindrical bale are also provided.
