DEVICE FOR REPLACEABLY CONNECTING A DRAG-HEAD TO A SUCTION PIPE

摘要

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