Abstract
A dragging type cutter head for a suction dredger has a cutting member that rotates about a horizontal axis and has at its periphery a series of cutting teeth disposed side-by-side in the axial direction. At the lowermost point in their rotation, the cutting teeth rotate in the dragging direction. The dragging head has an inlet opening for cut material, whose edges extend to the outer circle of rotation of the cutter teeth with the lower edge of that opening at the same level as the lower part of the cutting member. The cutting teeth are pivotal on horizontal axes spaced from that of the cutting member; and springs urge the cutting teeth about their axes in the cutting direction.
