and a suction pipe 10, wherein the first end of the suction pipe 10 is connected with the auxiliary suction machine 9, and the second end of the suction pipe is communicated into the dredging cavity 20.
Wherein, the suction pipe 10 is of a soft structure and can be folded, and when the dredging shovel 5 extends outwards, the suction pipe 10 can be stretched and unfolded, thereby adapting to the current environment. And supplementary suction machine 9 is close to shovel head 51 and sets up, scrapes the silt and transfers to the water in and when silt just begins to spill and scatter when shovel head 51, and the negative pressure that supplementary suction machine 9 produced will make silt be sucked in suction tube 10 immediately to directly get into dredging cavity 20 along suction tube 10, take out to the hydraulic pipe outside by the negative pressure of blow off pipe a again, thereby improve the extraction complete rate of silt.
Further, the shovel head 51 is curved in an arc shape, the auxiliary suction machine 9 is inclined, and the tail end of the shovel head 51 is disposed opposite to the front surface of the auxiliary suction machine 9. As shown in fig. 5, the front end of shovel head 51 is curved toward the rotation direction, and the sludge scraped by shovel head 51 will be accumulated along shovel head 51 and gradually move to the tail end of shovel head 51, so that it is easier to be sucked by auxiliary suction machine 9, and the sludge suction rate of auxiliary suction machine 9 is increased.
Further, in order to prevent the second end of the suction pipe 10 from being shaken out of the dredging cavity 20 when the outer cylinder 1 rotates, in this embodiment, the front end of the outer cylinder 1 is further provided with a fixing ring 13, the fixing ring 13 is located at the front end opening of the dredging cavity 20, and the second end of the suction pipe 10 is connected to the fixing ring 13, so as to fix the positions of the two ends of the suction pipe 10.
Further, the circumferential pusher 21 is a high-pressure water gun, and a water inlet pipe of the high-pressure water gun is arranged along the length direction of the sewage discharge pipe a. Wherein, the press setting of high-pressure squirt is outside at the water conservancy pipeline, and the high-pressure squirt is then fixed to be set up at the tail end of inner tube 2, and the rivers that the high-pressure squirt jetted can not hinder silt entering desilting chamber 20's process.
In addition, the inclination angle of the planet wheels of the Mecanum wheel 3 is smaller than 20 degrees, so that the power generated by the Mecanum wheel 3 is more deviated to the circular motion, even if the outer cylinder 1 moves for a unit distance, the number of turns of rotation is more, and the dredging work is more thorough. Moreover, the movable cavity can be further divided into a first cavity and a second cavity, the first cavity is used for installing telescopic driving, the second cavity is isolated from the first cavity, and the second cavity can adopt a floating and sinking mechanism similar to a submarine, so that when the water conservancy dredging and dredging device acts on a vertical pipeline with a water body, the water conservancy dredging and dredging device can float or descend in the water body more quickly.
