[0060] As a specific embodiment of the present invention, please refer to Figure 3 The suction mechanism 300 disclosed in the embodiment of the present invention includes a suction pump 301, a suction pipe 302 and a suction hood 303, wherein the suction pump 301 is connected to the suction pipe 302, and the suction pump 301 can provide suction; one end of the suction pipe 302 is connected to the suction hood 303, and the other end is connected to the mud-water separation mechanism 400, the suction hood 303 is arranged at the inlet of the suction pipe 302, and the suction port of the suction hood 303 is arranged toward the stirring member 203.

[0061] The suction pump 301 may be disposed inside the suction pipe 302 or outside the suction pipe 302 , and the suction port of the suction pipe 302 is connected to the suction pipe 302 .

[0062] When the suction pump 301 is started, under the action of negative pressure, the suction pump 301 sucks the silt and water in the channel groove into the suction pipe 302, and the silt and water enter the mud-water separation mechanism 400 through the suction pipe 302 for separation.

[0063] In order to ensure that the stirred mud, sand and gravel can be sucked into the suction pipe 302 in a timely and effective manner, the suction port of the suction hood 303 disclosed in the embodiment of the present invention is arranged toward the stirring member 203.

Through the telescopic effect of the telescopic rod, the suction pipe 302 can be pushed or pulled back, so that the stirring element 203 can be flexibly adjusted up and down, left and right, and front and back, so that it can be maintained in the best stirring position, further improving the dredging effect.

[0068] The auxiliary bracket 600 may be a frame body or a rod body, as long as the connection between the support frame 202 and the suction pipe 302 can be achieved.

[0069] When the dredging ship is working, the operator can adjust the position of the support frame 202 and the stirring member 203 through the adjustment mechanism 500 according to the siltation situation and water depth of the channel. After the adjustment is completed, the drive motor is started, and the drive motor drives the rotating shaft and the stirring blades to rotate. Under the rotation of the stirring blades, the silt is gradually stirred to loosen and mix evenly.
