Abstract
An apparatus for emptying sacks filled with bulk material comprising a feeder which transports filled sacks within the apparatus; a circular knife located such that, when the filled bag passes through the feeder, the circular knife cuts the bottom and sides of the bag; a receiving hopper for the bulk material; and an emptying assembly. The emptying assembly is comprised of two swivel plates which swing upwards and towards each other and an upright abutment plate which separately supports each side of the sack. In operation, the circular knife cuts the sack and the feeder loads the cut sack onto the swivel plates which swivel upward forcing the sack into contact with the abutment plate. Gravity forces the material from the sack into the receivimg hopper.
