Abstract
A dragging type suction head for a suction dredger having a suction tube which extends downwardly and rearwardly from a vessel at the lower end of which the suction head is mounted. In this suction head, enclosed by a housing which at least at a rear side leaves free an entrance opening, a cutter is mounted rotating in a direction opposite the direction of dredging, said cutter being a cylindrical body with cutting blades at its circumference which blades feed immediately into an intake section connected to the suction tube. Between the inner edges of the cutting blades and a cylindrical drum, space is provided to allow for a passage through which water can flow. The blades are mounted between discs that have sharp cutting edges.
