In embodiment 1, as shown in fig. 3, after each use, the screen 703 needs to be cleaned, small stones stuck inside the screen 703 are removed, the internal thread bushing 705 is rotated to rotate the external side of the thread 704, the internal thread bushing 705 is slowly separated from the bushing 708 under the action of the thread 704, the two sets of arc-shaped grooves 702 are rotated while the internal thread bushing 705 is rotated, the arc-shaped grooves 702 push the two sets of L-shaped rods 707 to approach each other under the action of the arc-shaped edges, so that the L-shaped rods 707 are slowly separated from the inside of the L-shaped grooves 16, the engagement between the L-shaped rods 707 and the L-shaped grooves 16 is released, so that the fixation between the fixing plate 701 and the mounting frame 8 can be released, when the internal thread bushing is completely separated from the bushing 708, the L-shaped rods 707 are also completely separated from the L-shaped grooves 16, at this time, the fixing plate 701 can be pulled to be separated from the mounting frame 8, the sleeve 708 is driven to move out of the inner part of the slot 17 to clean the screen 703.

In embodiment 2, as shown in fig. 5-6, the sludge absorbed by the dredging pump 4 falls into the collecting box 201, two sets of first driving motors 211 are turned on, the two sets of first driving motors 211 drive two sets of incomplete gears 204 to rotate at the same time, and because the teeth of the two sets of incomplete gears 204 are arranged in the same direction, when one set of incomplete gears 204 is meshed with the rack 207, the other set of incomplete gears 204 is not meshed, so that the two sets of incomplete gears 204 drive the rack 207 to slide back and forth in the chute 202 through the sliding block 205, the rack 207 drives the linkage rod 203 to slide in the chute 202, and finally drives the rolling wheel 208 to slide back and forth in the collecting box 201, so as to roll the sludge continuously back and forth, extrude the moisture in the sludge out through the filter plate 209, and as the sludge accumulates, the rolling wheel 208 on the upper edge can not rise at the high end, the linkage 203 is also raised until the collection bin 201 is full.

The working principle is as follows: before dredging, when the dredging depth of the mounting frame 8 needs to be adjusted, at the moment, the double-shaft servo motor 15 works to drive the two groups of rotating shafts 14 to rotate, the rotating shafts 14 can drive the second hinged rods 13 to rotate, the side of the second hinged rods 13 drives the hinged parts of the first hinged rods 12 and the second hinged rods 13 to move downwards, but as the telescopic rods 5 are hinged on the first hinged rods 12 and the second hinged rods 13, the first hinged rods 12 always move downwards horizontally, the first hinged rods 12, the second hinged rods 13 and the telescopic rods 5 are in a triangular shape, when the mounting frame 8 is adjusted to a proper position, the double-shaft servo motor 15 is closed, so that the depth of the mounting frame 8 can be adjusted, at the moment, the second driving motor 11 drives the spiral knife 10 to rotate at a high speed to break stones inside silt, the dredging pump 4 conveys the silt to the inside the collecting box 201 through the second guide pipe 6 and the first guide pipe 3, two groups of first driving motors 211 are turned on, two groups of first driving motors 211 simultaneously drive two groups of incomplete gears 204 to rotate, because the teeth of the two groups of incomplete gears 204 are arranged in the same direction, when one group of incomplete gears 204 is meshed with the rack 207, the other group of incomplete gears 204 are not meshed, so that the two groups of incomplete gears 204 can drive the rack 207 to slide back and forth in the chute 202 through the sliding block 205, the rack 207 drives the linkage rod 203 to slide in the chute 202, finally the rolling wheel 208 is driven to slide back and forth in the collection box 201, sludge is continuously rolled back and forth, moisture in the sludge is squeezed out, the sludge is drained through the filter plate 209, the upper rolling wheel 208 rises without end, the linkage rod 203 rises along with the linkage rod until the collection box 201 is full, after each use, the screen 703 needs to be cleaned, small stones clamped inside the screen 703 are removed, the internal thread sleeve 705 is rotated to enable the internal thread sleeve 705 to rotate on the outer side of the thread 704, under the action of the thread 704, the internal thread sleeve 705 is slowly separated from the sleeve 708, the two groups of arc-shaped grooves 702 are rotated while the internal thread sleeve 705 rotates, the two groups of L-shaped rods 707 are pushed to be close to each other under the action of the arc-shaped edges, the L-shaped rods 707 are slowly separated from the inside of the L-shaped groove 16, clamping between the L-shaped rods 707 and the L-shaped groove 16 is released, fixing between the fixing plate 701 and the mounting frame 8 can be released, when the internal thread sleeve 705 is completely separated from the sleeve 708, the L-shaped rods 707 are also completely separated from the L-shaped groove 16, at the moment, the fixing plate 701 can be pulled to be separated from the upper surface of the mounting frame 8, the inside of the sleeve 708 slot 17 is driven to move out, and the screen 703 is cleaned.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
