Reciprocating blade bale cutter

摘要

A horizontally oriented three sided frame is adapted to hold a round hay bale. An endless chain driven conveyor in the floor of the frame causes the round bale to rotate about a longitudinal axis while simultaneously urging a portion of the perimeter of the bale against a sickle bar cutter arrayed just above the floor on one side of the frame. The cutter chops the hay bale into manageable portions for feeding to livestock. The sickle bar cutter includes a conventional reciprocating cutter bar with triangularly shaped cutting teeth arranged continuously along the bar. A specially designed blade guide allows the entire cutting surfaces of the teeth to extend past the blade guide as they reciprocate. This insures that the hay bale is fed rapidly into the reciprocating teeth since no blade guide teeth enter the cutting gaps between the cutting teeth as they reciprocate and thus do not interfere with the advancement of the hay bale into cutter.
