[0082] The use process of the environment-friendly dredging device for water damage engineering provided by the application is as follows:

[0083] When the limiting rod 507 is in the same plane as the outermost inclined surface limiting block 506, the cross drive plate 407 and the cross sleeve 408 are in a state of moving away from each other;

[0085] The silt is scooped up by the external conveying belt and transported into the inlet 105, and then enters the working tank 102 through the flow tank 104 and the inlet 106;

[0086] At the same time, the annular sleeve 6016 is in close contact with the annular table 6012, the fan-shaped plate 6015 and the cross-shaped driving plate 407 block the inside of the circular sleeve 601 into four sealed spaces, and the partition plate 6014 divides one of the spaces into two again.

[0087] When the cross-shaped driving plate 407 is driven to rotate back and forth, the sealed spaces on both sides of the partition plate 6014 will be repeatedly extruded, forming a piston movement, and the filtered sewage in the working tank 102 is sucked into the sealed spaces on both sides of the partition plate 6014 through the telescopic water suction pipe 604, the outer annular square pipe 602 and the pipeline I 608, and then transported to the water storage tank 103 for storage through the pipeline II 6010, the inner annular square pipe 603 and the telescopic water outlet pipe 605.

[0088] When the external motor drives the gear II 405 to rotate reversely, the threaded rod 406 and the limiting rod 507 also rotate reversely, and when the limiting rod 507 is limited by the flat side of the inclined surface limiting block 506, the threaded rod 406 and the limiting rod 507 cannot continue to rotate and move to the other side of the inclined surface limiting block 506 along the limiting groove 503, and when the limiting rod 507 and the threaded rod 406 move to the other inclined surface limiting block 506, the threaded rod 406 drives the cross-shaped driving plate 407 to separate from the extension plate 6013, and the cross-shaped driving plate 407 is clamped into the cross-shaped sleeve 408.

[0089] At this time, the cross-shaped driving plate 407 rotates forwardly, driving the cross-shaped sleeve 408 to rotate, and the cross-shaped sleeve 408 can drive the cross-shaped frame 306 and the inclined surface pushing block 307 to rotate, and the inclined surface of the inclined surface pushing block 307 can push the L-shaped pressing plate 301 to move to the corner side of the working tank 102 continuously, so as to extrude the silt entering the working tank 102 through the inlet 106 only, filter out the water in the silt, flow out through the water outlet groove 305, and temporarily store in the working tank 102, and then be transported to the water storage tank 103.
