[0041] Two L-shaped support legs 11 are fixedly arranged at the bottom end of the concrete frame 4 .

[0042] The pumping assembly includes a water pump 12 fixedly arranged at the top of the mixing frame 4, the water outlet end of the water pump 12 is connected to a water outlet pipe 13, one end of the water outlet pipe 13 passes through the top of the mixing frame 4 and is connected to the inside of the mixing frame 4, and the water outlet end of the water pump 12 is connected to a water inlet pipe 14;

[0043] A filter frame 15 is fixedly provided at one end of the water inlet pipe 14 , and a filter screen plate 16 is fixedly provided on the inner wall of the opening of the filter frame 15 .

[0044] The power assembly includes a first motor 17 fixedly mounted on the top of the fixed mounting frame 5. The first motor 17 is disposed on one side of the rotating rod 6. A rotating shaft 18 is fixedly mounted on the output shaft of the first motor 17. One end of the rotating shaft 18 is rotatably connected to the inner wall of the fixed mounting frame 5 via a bearing seat 19. A first gear 20 is fixedly mounted on the outer end of the rotating shaft 18. A second gear 21 is fixedly mounted on the outer end of the rotating rod 6. The first gear 20 and the second gear 21 are meshed with each other.

[0045] The support plate 2 is fixed on the sediment transport device 1. The sediment transport device 1 is an existing transport tool, which can be a ship or the like. The sediment transport device 1 moves to a place where sediment suction is required, and the top sediment suction pipe 3 is connected to the mud pump so that the concrete frame 4 and the L-shaped support leg 11 are inserted into the sediment layer. The first motor 17 is started, and the output shaft of the first motor 17 drives the rotating shaft 18 to rotate, and the rotating shaft 18 drives the first gear 20 to rotate, and the first gear 20 drives the second gear 21 to rotate, and the second gear 21 drives the rotating rod 6 to rotate, and the rotating rod 6 drives the spiral blade 7, the connecting rod 8 and the plurality of second stirring rods 10. The connecting rod 8 rotates, and the connecting rod 8 drives the multiple first stirring rods 9 to rotate. The rotating multiple first stirring rods 9 will stir the silt layer, and the rotating spiral blades 7 will send the viscous silt into the mixing frame 4. At this time, the water pump 12 is started, and the water flows into the mixing frame 4 through the water inlet pipe 14 and the water outlet pipe 13. The filter frame 15 and the filter screen plate 16 will filter the impurities in the water. The rotating multiple second stirring rods 10 will stir and mix the viscous silt and water, so that the silt can be diluted. The diluted silt falls into the silt placement area on the silt transport device 1 through multiple silt suction pipes 3 and the mud pump.

[0046] The present invention stirs the silt layer by a plurality of rotating connecting rods 8, and then sends the viscous silt to the inside of the mixing frame 4 to mix with water through the spiral blades 7, so that the silt suction is simple and convenient, the suction speed can be increased, and the silt is too viscous to cause the silt suction pipe 3 to be blocked, so that the suction and cleaning of the silt can be carried out continuously, and the efficiency of the silt suction and cleaning is effectively improved, and the overall suction and cleaning effect is good. This embodiment specifically solves the problem that when the silt suction device in the prior art is used to suck and clean the silt in the waterway, most of them are directly installed on the silt transportation device, and then the silt is sent to the water area where the silt needs to be cleaned, and then the pipe for sucking the silt is inserted into the silt, and then the silt is pumped to the silt transportation device by the mud pump. In this silt suction method, if the silt is relatively viscous, the silt is easy to block the suction pipe, which will affect the progress of the silt suction and cleaning work, thereby reducing the efficiency of the silt suction and cleaning, and the suction and cleaning effect is not good enough.

[0048] The limiting assembly includes a cavity 29 opened inside the plug-in block 27, two limiting plates 30 are arranged inside the cavity 29, limiting blocks 31 are fixedly provided on the outside of the limiting plates 30, one end of the two limiting blocks 31 respectively extends to the top and bottom ends of the plug-in block 27, the outer side of one end of the limiting block 31 is an arc surface, a spring 32 is fixed between the two limiting plates 30, and two fixed guide rods 33 are fixedly provided inside the cavity 29, the two fixed guide rods 33 are respectively arranged on both sides of the spring 32, and the two ends of the fixed guide rods 33 respectively pass through the two limiting plates 30.

[0049] The clamping assembly includes two connecting plates 34 arranged on one side of the support plate 2, the bottom connecting plate 34 is fixedly connected to one side of the support plate 2, two symmetrical arc-shaped clamping plates 35 are provided on one side of the connecting plate 34, and an anti-slip pad 36 is fixedly provided at the inner end of the arc-shaped clamping plate 35. The inner end of the anti-slip pad 36 contacts the outer end of the sediment suction pipe 3, a first adjustment assembly is provided on the inner side of the connecting plate 34, and a second adjustment assembly is provided between one side of the support plate 2 and the top connecting plate 34.

[0050] The first adjustment component includes a first slide groove 37 opened on one side of the connecting plate 34, two first sliders 38 are arranged inside the first slide groove 37, one side of the two first sliders 38 are respectively fixedly connected to the two arc-shaped clamping plates 35, a bidirectional screw rod 39 is rotatably connected inside the first slide groove 37, one end of the bidirectional screw rod 39 passes through the two first sliders 38 and extends to one end of the connecting plate 34, the bidirectional screw rod 39 and the two first sliders 38 are connected by threads and the threads are in opposite directions, a second motor 40 is fixedly provided at one end of the connecting plate 34, and one end of the bidirectional screw rod 39 is fixedly connected to the output shaft of the second motor 40.

[0051] The second adjustment component includes a second slide groove 41 opened on one side of the support plate 2, a second slider 42 is provided inside the second slide groove 41, one side of the second slider 42 is fixedly connected to the top connecting plate 34, a threaded rod 43 is rotatably connected inside the second slide groove 41, the top end of the threaded rod 43 passes through the second slider 42 and extends to the top end of the support plate 2, the threaded rod 43 and the second slider 42 are connected by threads, a third motor 44 is fixedly provided on the top end of the support plate 2, and the output shaft of the third motor 44 is fixedly connected to the top end of the threaded rod 43.

[0052] The sediment suction pipe 3 is placed between the two arc-shaped clamping plates 35 and the anti-skid pad 36, and the second motor 40 is started. The output shaft of the second motor 40 drives the bidirectional screw rod 39 to rotate. Since the bidirectional screw rod 39 is threadedly connected to the two first sliders 38, the two first sliders 38 approach each other as the bidirectional screw rod 39 rotates. The two first sliders 38 drive the two arc-shaped clamping plates 35 and the anti-skid pad 36 to clamp and fix the sediment suction pipe 3. When connecting multiple sediment suction pipes 3, first use the clamping assembly at the bottom to clamp and fix one sediment suction pipe 3, and then put another sediment suction pipe 3 on the top of the fixed sediment suction pipe 3. The sealing gasket 22 and the connecting flange 23 at the connection of the two sediment suction pipes 3 are made to fit each other, and then the first limit frame 24 and the second limit frame 25 are clamped at the outer ends of the two connecting flanges 23. At this time, the plug-in block 27 will be inserted into the plug-in slot 28, and the arc surface of the limit block 31 on the plug-in block 27 will enter the cavity 29 under the pressure of the inner wall of the plug-in slot 28. The limit block 31 drives the limit plate 30 to compress the spring 32. When the plug-in block 27 passes through the plug-in slot 28, the limit plate 30 drives the limit block 31 back to its original position under the elastic force of the spring 32. In this way, the limit block 31 will limit and fix the two contacting connecting blocks 26 together;

[0053] After the multiple silt suction pipes 3 are connected and fixed, the top clamping assembly clamps and fixes the silt suction pipe 3, and the bottom clamping assembly releases the clamping and fixation of the silt suction pipe 3, and the third motor 44 is started. The output shaft of the third motor 44 drives the threaded rod 43 to rotate. Since the threaded rod 43 is threadedly connected to the second slider 42, the second slider 42 moves downward with the rotation of the threaded rod 43, and the second slider 42 drives the top clamping assembly to move downward, and the top clamping assembly drives the silt suction pipe 3 and the concrete frame 4 to move downward, so that a small range of adjustment can be achieved. The depth of the concrete frame 4 is adjusted downward, so that the bottom end of the concrete frame 4 can be better inserted into the silt layer. The present invention fixes the connection between the two silt suction pipes 3 through the first limit frame 24 and the second limit frame 25, so that the connection between the multiple silt suction pipes 3 is relatively simple and convenient, and then the second adjustment component is used to adjust the depth of the silt suction pipe 3 and the concrete frame 4 in a small range, so that the bottom end of the concrete frame 4 and the L-shaped supporting leg 11 can better enter the silt layer, and then the silt in the waterway can be better sucked and cleaned, which is more practical.
