When the river channel needs to be desilted, the silt is pumped into the box through the collection assembly, and then the silt is separated from the debris and mud by the filter mud frame and the traction assembly. Before cleaning the silt, the larger debris is separated, which reduces the frequency of cleaning the filter screen by the staff and improves the work efficiency of the desilting operation.

[0004] In the above patent, by separating the larger debris in the sludge before cleaning it, the frequency of cleaning the filter by the staff is reduced, and the work efficiency of the dredging operation is improved. However, it is difficult to pre-treat the sludge before treating the sewage, resulting in the inability to treat the pollutants in the sludge. At the same time, it is difficult to break up the lumped sludge. Because of its hardening and density, the lumped sludge is usually more difficult to remove than the loose sludge. If these lumps cannot be broken up, the dredging pipe will be blocked, thereby extending the cleaning cycle. Summary of the invention

[0014] A method for using a silt removal device for drainage construction, using the above-mentioned silt removal device for drainage construction, comprising the following steps: Step 1: The dredging frame is placed in the area to be dredged and the servo motor drives the connecting rod to rotate, the connecting rod rotates to drive the hollow rod to rotate, the hollow rod rotates to drive the curved rod to rotate, and the curved rod rotates to preliminarily break up the agglomerated silt that has entered the dredging frame; Step 2: The rotation of the hollow rod drives the fixed rod to rotate. The fixed rod rotates and contacts the arc surface of the fixed block and squeezes the fixed block. The fixed rod moves downward under the reaction force of squeezing the fixed block. The downward movement of the fixed rod drives the hollow rod to move downward; Step 3: The hollow rod moves downward to drive the curved rod to move downward, and the hollow rod continues to rotate to drive the fixed rod to continue to rotate. The fixed rod continues to rotate to break away from the contact with the fixed block, so that the hollow rod moves upward and resets under the elastic force of the reset spring; Step 4: The hollow rod moves upward to reset, driving the curved rod to move upward to reset. The curved rod moves back and forth longitudinally to further break up the agglomerated sludge that has entered the dredging frame. At the same time, the sludge pump operates to extract the sludge in the dredging area through the dredging pipe.

[0015] The present invention provides a dredging device for drainage construction, which has the following beneficial effects: (1) The invention uses a drug delivery pipe and a drug spraying port to spray the inside of a dredging frame during sewage treatment, and the sprayed drugs can remove harmful substances in the sludge and improve water quality.

[0016] (2) The invention drives the curved rod to rotate by rotating the hollow rod, and the rotation of the curved rod preliminarily breaks up the agglomerated sludge entering the dredging frame. By breaking up the sludge, the agglomerated sludge can be effectively turned into loose particles or mud, thereby helping to improve the efficiency of dredging. The curved rod is driven to move upward and reset by the upward movement of the hollow rod, and the reciprocating longitudinal movement of the curved rod further breaks up the agglomerated sludge entering the dredging frame. The reciprocating curved rod can apply forces in different directions to the agglomerated sludge in a relatively short period of time, which helps to quickly break up the agglomerated sludge, thereby quickly breaking up the agglomerated sludge structure, so that the agglomerated sludge can be removed in a short period of time, further improving the efficiency of dredging.

[0017] (3) In the present invention, the U-shaped rod moves downward to hit the linkage rod to generate vibration. The vibration generated by the linkage rod drives the T-shaped rod to resonate together. The vibration can effectively increase the pushing efficiency of the T-shaped rod, thereby improving the efficiency of pushing foreign matter. The linkage rod rotates to drive the T-shaped rod to rotate. The T-shaped rod contacts the bottom of the filter plate and rotates simultaneously to achieve the effect of intermittently pushing foreign matter at the bottom of the filter plate. The intermittent pushing of the T-shaped rod can effectively push away foreign matter at the bottom of the filter plate, thereby maintaining unobstructed extraction of the dredging pipe. In addition, the intermittent pushing can reduce the wear on the filter plate and increase the service life of the filter plate.

[0018] (4) The invention drives the buffer plate to reset by swinging the buffer frame, and the buffer plate reset drives the salvage rod to swing and reset. The salvage rod swings back and forth horizontally to salvage the strip-shaped foreign matter near the salvage hole. The salvage of the strip-shaped foreign matter by the salvage rod can prevent the strip-shaped foreign matter from blocking the salvage hole, thereby effectively improving the working efficiency and cleaning effect of the dredging device. The slow flow of liquid inside the buffer frame causes the buffer plate to move slowly to buffer the salvage rod. The slow movement of the buffer plate can effectively disperse the impact force, reduce the instantaneous and violent impact of the salvage rod, and thus avoid damage or deformation of the salvage rod.

9. A method for using a silt removal device for drainage construction, using the silt removal device for drainage construction according to claim 8, characterized in that: The following steps are involved: Step 1: The dredging frame (1) is placed in the area to be dredged and cleared, the servo motor (7) operates to drive the connecting rod (8) to rotate, the connecting rod (8) rotates to drive the hollow rod (9), the hollow rod (9) rotates to drive the curved rod (12), and the curved rod (12) rotates to preliminarily break up the agglomerated sludge that has entered the dredging frame (1); Step 2: The hollow rod (9) rotates to drive the fixed rod (10) to rotate. The fixed rod (10) rotates to contact the arc surface of the fixed block (11) and squeezes the fixed block (11). The fixed rod (10) moves downward due to the reaction force of squeezing the fixed block (11). The downward movement of the fixed rod (10) drives the hollow rod (9) to move downward. Step 3: The hollow rod (9) moves downward, driving the curved rod (12) to move downward, and the hollow rod (9) continues to rotate, driving the fixed rod (10) to continue to rotate. The fixed rod (10) continues to rotate and disengages from the fixed block (11), so that the hollow rod (9) moves upward and resets under the elastic force of the reset spring (13); Step 4: The hollow rod (9) moves upward and resets, driving the curved rod (12) to move upward and reset. The curved rod (12) moves back and forth longitudinally to further break up the agglomerated sludge entering the desilting frame (1). At the same time, the sludge pump (3) operates to extract the sludge in the area to be desilted through the desilting pipe (2).
