It also provides a solid protective barrier for the internal precision components through the protective plates 12 fixedly connected on its left and right sides. The front side of the protective plate 12 is tightly fitted with the rear side of the pad 11, and the left and right sides of the long rod 13 are also rotatably connected to two wheels 16. The outer wall of the wheel 16 is tightly engaged with the anti-slip belt 14 to achieve efficient power transmission.

[0038] Working principle: The water in the water tank 3 is adsorbed by the high-pressure pump 19 and then transferred to the high-pressure spray gun 18. The motor 21 then drives the disc 17 to rotate. The short rod 25 at the bottom of the disc 17 rotates accordingly, thereby driving the high-pressure spray gun 18 to rotate up and down, so as to achieve the purpose of adjusting the angle, improve the comprehensiveness and thoroughness of dredging, and reduce the possibility of residual sediment. By reasonably adjusting the angle of the high-pressure water gun, the impact direction and force of the water flow can be controlled, and the damage to the channel wall can be reduced, thereby reducing the cost of channel repair and maintenance, enhancing the adaptability of the equipment, and improving the efficiency and quality of dredging.

[0039] After the mud suction device 205 is started, silt and other debris enter from the front end of the fixed block 201, and the large objects are broken into pieces by the crushing and cutting of the crusher 204. Then, when it reaches the filter screen 203, it passes through the passable part of the silt, and the slightly larger ones are still cut by the crusher 204 at the rear end. After completion, it is transmitted to the water pipe 202 through the filter barrel 207 and discharged to a specific location, thereby achieving the effect of clearing the silt, speeding up the dredging progress and improving the efficiency of the entire dredging. Especially when the silt contains a large number of hard objects, the advantages of crushing and dredging are more obvious, and at the same time, it reduces the blockage and transportation difficulties caused by the poor fluidity of the silt, reduces the power requirements of the transportation equipment, and saves energy consumption.
