Compared with the prior art, the regular pyramid-shaped ground breaking device is made of solid steel and provided with protruding thorns in the pushing direction, and the ground breaking function can be achieved in the pipe jacking process. At the bottom end of the ground breaking device, each edge of the regular pyramid is provided with the corresponding hinge device, and the hinge devices are fixedly connected with the bottom end of the ground breaking device through screws and can be detached and replaced. The other ends of the hinge devices are connected with the blade type blades with the protruding thorns, in other words, the blades are connected with the ground breaking device through hinges, the blades can be replaced at any time, the broken blade can be detached, and use is convenient.

The invention provides a trailing suction dredger with a hob head driven by an external rotor motor. It includes: the hob harrow head, which is connected to the hull through the harrow arm, and the hob harrow head includes a harrow head fixed body, a harrow head movable cover, a drum equipped with harrow teeth, an external rotor motor, and a hydraulic device and high-pressure flushing elbow; the rake head fixed body is rotatably connected with the movable cover, and a high-pressure flushing elbow is installed above; the roller with rake teeth is installed under the movable cover, including the roller, tooth seat and rake teeth, and the roller is sealed There is an external rotor motor built into the ground, which drives the drum to rotate around the horizontal axis through the stator and rotor; the entire drum with rake teeth is rotatably connected to the movable cover of the rake head, and can rotate within a certain angle range with the movable cover relative to the fixed body of the rake head. The trailing suction dredger provided by the present invention can effectively control the weight of the rake head, reduce the axial restraint attachment, and increase the effective cutting width, thereby greatly improving the soil-breaking ability of the rake head of the dredger and the operation efficiency of dredging hard soil .
