Abstract
Contaminated fine sediment is removed from surfaces beneath a body of water by a shrouded, self-cleaning, wheel-guided, open suction attachment for a swinging ladder suction dredge with articulating capabilities. The attachment comprises a wheel-guided, suction assembly in which the slurry is contained in a shroud. The shroud is attached to a head plate, and is designed to both enclose the solid particles suspended as a result of the removal operation, and to direct the suspended material to the mouth of the suction pipe. Inside the area surrounded by the shroud is a gatling plate rotated by a hydraulic motor mounted just above the shroud and head plate.
