[0002] The cutter suction type dredging head in the existing dredging machinery adopts the form of a cutter or a cutter combined with high-pressure water flushing to break the soil and loosen the mud.

[0003] This makes the soil sucked into the pipeline often in large clumps, resulting in large head loss along the way for long-distance transportation of the sludge, high energy consumption, and easy pipeline blockage. Long-distance transportation of the sludge is often difficult to implement, and the equipment is expensive. Chinese Patent (Publication No. CN101092819B) discloses a flying rope cutter suction type underwater dredging head, which uses a high-speed rotating rope to loosen and crush the hardened mud and sand, and quickly mixes it with water to become a liquid slurry with good flow properties, and has low cost. However, in the above document, the rope is tied to the flywheel through the holes on both sides of the flywheel. However, when the flywheel drives the two ropes to rotate, the flywheel and the ropes will be worn due to centrifugal force, and the ropes are prone to breakage due to wear, resulting in short service life of the ropes.

[0033] The front and rear ends of the two insertion blocks 6 are both provided with positioning grooves for allowing the positioning blocks 61 to be located in the interiors of the positioning grooves. The positioning blocks 61 are inserted into the interiors of the positioning grooves. When the two positioning blocks 61 are inserted into the positioning grooves at the front and rear ends of the insertion blocks 6, the two positioning blocks 61 can fix the insertion blocks 6 in the connecting blocks 4, and the two ropes 3 can be installed on the opposite sides of the two connecting blocks 4.
