(under subclass 304) Apparatus wherein the unloading means includes at least one device consisting of a rotatably driven, vertical shaft having flexible, arm-like elements extending radially (i.e., in a generally horizontal plane) therefrom.
(1) Note. The elements may serve in conjunction with other structure (e.g., a helical thread formed on the vertical shaft) in unloading the receptacle, or they may act alone in doing so.
(2) Note. The device sometimes (e.g., when unloading ensilage) serves also to dislodge or loosen the material for movement.
(3) Note. The elements may droop to a position alongside the shaft when the latter is not in motion.
