Claims

[Scope of utility model registration request]

In a drag head dredger that dredges sediment on the water bottom by towing a drag head attached to the tip of the drag arm so that it can rotate vertically, an L-shaped tapered booster is attached to the curved part of the drag head along the axis of the drag arm. A discharge pipe for discharging pressurized water from the booster pump has a connection opening, and the other end of the drag arm is connected to a trough for discharging dredged earth and sand to the dredger hopper so as to be able to rotate in the vertical direction, The booster drag head, which is towed with its opening facing in the direction of travel, draws sediment from the bottom of the water into the drag head from the opening, and the pressurized water discharged from the discharge pipe opening transports it from the trough to the dredger's hopper via the drag arm. Booster drag head dredger discharging inward.
