  • Patent number: 6357213
    Abstract: The water vegetation removal system includes a stationary barge and at least one motorboat equipped with a plow blade or vegetation rake for plowing vegetation on the surface of a body of water into the vicinity of the barge. The system includes a barge with a diesel engine mounted at one end and a pump box attached to the barge which provides a watertight chamber for housing a dredge pump powered by the engine. A hopper box with a spillway gate which may be lowered to admit water is attached to the pump box. A water tray is formed by a pair of walls hingedly attached to the hopper box to funnel vegetation into the hopper box. Vegetation is drawn into the water tray and hopper box by suction applied by an intake pipe from the dredge pump which extends into the hopper box. Vegetation is drawn into the pump and macerated, then discharged through a flexible discharge pipe to the shore for transport.
