ABSTRACT:
A material debagging apparatus includes a receptacle movable between upright loading and inverted dumping positions. The receptacle defines a bagged material holding chamber with a closed bottom and an open top. A rupturing mechanism in the form of a pair of generally parallel drums having circumferential rows of teeth thereon is carried on the receptacle adjacent the closed bottom of the chamber. The rupturing mechanism is operable for rupturing a bag at least partially filled with material and disposed in the chamber with the bottom of the bag overlying the rupturing mechanism. A drive mechanism is coupled to the drums of the rupturing mechanism for transmitting rotary power thereto to cause counterrotation of the drums. A clamping device normally disposed in a clamping condition is mounted on the receptacle adjacent the open top of the chamber. The clamping device clamps and secures the top of the bag while the bottom of the bag is ruptured by the rupturing mechanism as the receptacle is moved from its loading to its dumping position thereby emptying the material from the ruptured bag.
