Device for replaceably connecting a drag-head to a suction pipe.

摘要

Suction pipe (1) with drag head for a dragging suction dredger, said pipe being provided at its lower end with a connection piece (3) of the drag head in which the essentially rectangular throughflow opening of the drag head passes into the circular cross section of the pipe. A replaceable end piece or drag head part (13), which forms the suction aperture or suction slit, is or can be detachably fixed at the side facing the connection piece by means of a quick action coupling to the connection piece in such a way that it rotates about a horizontal cross-shaft.
