Abstract:
The present invention relates to a draghead (1) for a trailing suction hopper, comprising a visor (2), revolvable around a first axis (6) for removing soil, and a suction line (31) connected to the visor (2) for the removal of the loosened soil, characterised in that the draghead (1) is provided with a pressure plate (21), which comprises a number of mainly disc-shaped penetrating bodies (22) on the soil-facing side of the pressure plate (21), in such a way that their circumferential edge (23) is capable of transferring forces to the soil.
