Abstract
The invention relates to a dragging type head (1) of a suction dredger, the head having a driven cutting device in front of the suction tube mouth, which cutting device (5) rotates about a horizontal transverse axis and has cutting blades at its outer circumference. The main part of the cutting device (5) is enclosed by a cap (6) connected to the suction tube mouth (4). The cutting blades (e.g. 15,16,17,18,19 and 16', 17', 18', 19') are arranged in the form of several V-shaped patterns (11,12) upon the circumference with a channel digging type blade (15,20,27) at the leading top of each V. All the blades are shaped such that they move the cut material laterally towards the plane of the channel digging blades (15,20,27) and all the blades may be in the shape of a plough (28).
