Abstract
A refuse compactor, particularly for household refuse, has an upwardly open container mounted in a supporting frame and a pressure platen movable into and out of the container. A parallelogram drive for the platen is provided and includes a horizontal guide, a carriage which is movable along the guide, at least two pair of levers mounted for pivoting about a common pivot axis and each having ends connected to the platen and to the carriage respectively, a screw spindle connected with the carriage and with a motor so as to effect shifting of the carriage when it is rotated by the motor, and reinforcing members which connect at least two of the levers to form a structural unit. A traverse member is mounted in the frame above the platen remote from the motor, and a pair of guide levers is provided, each having one end pivoted to one of the levers of one pair, and another end connected to the traverse member. A bearing journals one end of the screw spindle and the other end is driven by the motor.
