The top of the collecting box 10 is provided with a silt suction pipe 11, and the silt suction work is performed at the bottom of the riverbed through the silt suction pipe 11. This is the prior art and will not be described in detail.

[0031] Reference Figure 1 and Figure 4The outer wall of the collecting box 10 is fixedly connected with a fixing seat 12, and the inner wall of the fixing seat 12 is penetrated and rotatably connected with a screw rod 13. The screw rod 13 is a common mechanical transmission element, which is usually composed of a spiral texture on the surface of a cylindrical rod body, which can allow two sets of matching sliders 14 to move closer or separate. The outer wall of the screw rod 13 is provided with a slider 14, which matches the screw rod 13 and allows the slider 14 to move laterally along the outer wall of the screw rod 13. The outer wall of the slider 14 is fixedly connected with an extrusion plate 15, and the extrusion plates 15 are brought closer to each other to squeeze out the water in the sludge. The filter frame 16 is fixedly connected to the inner wall of the collecting box 10, and a filter screen is arranged on the filter frame 16 to separate the sludge and the water. The outer wall of the collecting box 10 is hinged with a hinged door 17. When the collecting box 10 is in use, the hinged door 17 can be closed. The hinged door 17 can be opened when the sludge in the collecting box 10 is cleaned. The outer wall of the collecting box 10 is provided with a pipe to allow the filtered water to flow out of the pipe. The squeezing plate 15 passes through and is slidably connected to the inner wall of the collecting box 10. The squeezing plate 15 is slidably connected to the top of the filter frame 16.

[0032] Reference Figure 1-Figure 3 The inner wall of the bottom end of the movable block 3 is fixedly connected to one end of the return spring 4. When the limit block 5 moves upward, the return spring 4 will be compressed. When resetting, the limit block 5 is reset with the elastic force of the return spring 4. The other end of the return spring 4 is fixedly connected to the top of the limit block 5. The limit block 5 penetrates and is slidably connected to the inner wall of the movable block 3. The limit block 5 is plugged into the inner wall of the limit groove 9. The limit groove 9 is provided with multiple groups, which can position the movable block 3 at the specified position of the T-shaped frame 2. The top of the movable block 3 is hinged One end of the rod 6 is hinged. Since the length of the hinged rod 6 is fixed, when the movable block 3 moves one end of the hinged rod 6 to the right, the other end of the hinged rod 6 will bring the connecting frame 7 closer to each other. On the contrary, when the movable block 3 moves one end of the hinged rod 6 to the left, the other end of the hinged rod 6 will separate the connecting frame 7 from each other. The other end of the hinged rod 6 is hinged to the top of the connecting frame 7, and the connecting frame 7 is rotatably connected to the top of the T-shaped frame 2. The blocking mechanism includes a cleaning net 8, which is fixedly connected to the outer wall of the connecting frame 7.

[0033] Working principle: First, when it is necessary to adjust the blocking range of the cleaning net 8 according to the width of the river channel, it is only necessary to move the limit block 5 upwards and compress the reset spring 4 to separate the limit block 5 and the limit slot 9, and then move the movable block 3 to the right to let the movable block 3 move to the right with the hinged rod 6, and let the hinged rod 6 bring the connecting frame 7 and the cleaning net 8 closer to each other. According to the width of the river channel, when it is necessary to limit the movable block 3, it is only necessary to loosen the limit block 5 and use the reverse elastic force of the reset spring 4 to reset the limit block 5, so that the limit block 5 is plugged into the inner wall of the limit slot 9 to complete the limitation of the entire connecting frame 7 and the cleaning net 8. When the hull 1 is traveling in the river channel to absorb silt, the cleaning net 8 will push the floating objects on the river channel to move. When the silt absorption is completed, all the floating objects in the river channel can be gathered together for subsequent cleaning to reduce the impact of floating objects on silt absorption. When adjusting again, just follow the above steps.

[0034] When sucking silt, the silt suction pipe 11 is driven by an external device to suck silt from the bottom of the river channel, and the silt and water are collected in the collection box 10, and the filter frame 16 is used to separate the silt and water. When the water in the silt needs to be squeezed, the screw rod 13 is rotated to make the two groups of sliders 14 bring the squeezing plate 15 closer to each other, and the squeezing plate 15 is allowed to slide along the top of the filter frame 16, so that the squeezing plate 15 squeezes the silt to discharge the water in the silt and minimize the weight of the hull 1. After the squeezing is completed, the screw rod 13 is rotated in the opposite direction to make the two groups of sliders 14 bring the squeezing plate 15 to separate and reset.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
