ABSTRACT:
A suction device for clearing the bottom of waterways includes a suction end having an inlet opening. Mounted to the horizontal edges of the inlet opening are either forcedriven conveyor screws or triangular flanges, with rollers mounted on the vertical edges of the inlet opening. The rollers in cooperation with either the triangular flanges or the conveyor screws turn material snagged in the waterway endwise into a suction pipe terminating at the suction end. Debris sucked into the suction pipe is delivered to a load basket at the other end of the suction pipe. The loading basket is constructed for lifting from the water by means such as a crane, and further constructed for unloading from the bottom thereof.
