It is also called a water project. In the process of water diversion in water conservancy projects, artificial ditches are often used to divert water. During the long-term use of ditches, a lot of mud and silt are often deposited inside, which causes the water flow in the ditch to be blocked. Therefore, it is necessary to regularly desilt the water diversion ditch.

When the pull block is displaced away from the support rod, the slider can move up or down on the inner wall of the support rod, and the connecting rod rotates around the rotating shaft, and the fixed ring drives the dredging end of the dredging pipe to adjust upward or downward, thereby adjusting the dredging angle of the dredging pipe, and realizing the function of multi-angle and efficient dredging.

There is a water-permeable hole 9, and the thread pitch of the first threaded rotating rod 8 corresponding to the water-permeable hole 9 is gradually set, and the pitch gradually becomes smaller, thereby forming a slight squeezing effect on the lifted sludge, squeezing out the water inside the sludge and discharging it through the water-permeable hole 9, reducing the water content of the sludge, and the support ring 4 is evenly provided with perforations. The setting of the perforations facilitates the water to flow down through the support ring 4. All support rings 4 are provided with perforations to form a connecting effect.

[0025] The first threaded rotating rod 8 is driven by the motor 7 to rotate, and the first inner sleeve 5 is cooperated to clean the sludge. At the position of the water permeable hole 9 in the first inner sleeve 5, the water in the sludge penetrates out of the first inner sleeve 5 through the water permeable hole 9 and enters between the first inner sleeve 4 and the first outer sleeve 3 to be discharged, thereby reducing the water content in the sludge. The spiral pitch of the first threaded rotating rod 8 is reduced, so that the sludge is slightly squeezed, further reducing the water content in the sludge, thereby effectively avoiding a large amount of sewage being carried when the sludge is cleaned, thereby effectively reducing the holding pressure of the holding container, and facilitating the dredging work.

[0034] The working principle of the utility model is:

[0035] When in use, the inclination angle of the U-shaped frame 2 is adjusted by the hinged relationship between the supporting base frame 1 and the U-shaped frame 2, thereby controlling the inclination angle of the first threaded rotating rod 8. During this process, the arc rod 15 slides along the fastener 16. When the angle is adjusted appropriately, the first hand-tightening bolt 17 is tightened, so that the first hand-tightening bolt 17 is inserted into the insertion hole 26, thereby forming a fixing effect.

[0036] By inserting the plug block 24 into the slot 22, the second hand-tightening bolt 23 is rotated so that the second hand-tightening bolt 23 is inserted into the fixing hole 25, so that the second threaded rotating rod 21 is connected to the first threaded rotating rod 8 as a whole, and by docking the connecting flange 20, the second outer sleeve 18 is connected to the first outer sleeve 3 as a whole, thereby extending the dredging distance.

[0037] The threaded handle 13 is turned to drive the first inner sleeve 5 to move through the connecting piece 14, so that the first outer sleeve 3 can move through the cooperation of the guide sleeve 11 and the slider 12 with the slide groove, thereby facilitating the front end of the device to be inserted into the silt for dredging operations.

[0038] Start the motor 7, which drives the first threaded rotating rod 8 to rotate, and at the same time drives the second threaded rotating rod 21 to rotate, and cooperates with the first inner sleeve 5 and the second inner sleeve 19 to rotate and draw the sludge in. When the sludge passes through the water permeable hole 9 of the first inner sleeve 5, the sewage in the sludge is discharged through the water permeable hole 9, and the sludge is continued to be lifted up and squeezed by the gradually changing first threaded rotating rod 8, further squeezing out the sewage therein, reducing the sewage content, and finally the sludge is transported to the sewage pipe 10 for discharge.
