Specific embodiments

[0022] The following further describes the specific embodiments of the present utility model in conjunction with the attached drawings. The descriptions of these embodiments are used to help understand the present utility model, but do not constitute a limitation to the present utility model. In addition, the technical features involved in the following various embodiments of the present utility model can be combined with each other as long as they do not conflict with each other.

[0023] See Figures 1 to 3 , the present utility model relates to a silt removal device, including a sewage suction pipe 1 and a mounting frame. One end of the sewage suction pipe 1 is a connection end, and the other end of the sewage suction pipe 1 is a sewage suction end; the mounting frame is used to fix the sewage suction pipe 1 on a dredging vehicle and connect the connection end of the sewage suction pipe 1 to a sewage suction pump provided on the dredging vehicle; during dredging, the sewage suction end of the sewage suction pipe 1 extends into the channel, and under the negative pressure generated by the sewage suction pump, the silt in the channel is sucked out; when the dredging vehicle moves, it drives the sewage suction pipe 1 to move along the channel to complete dredging; two sewage collection parts are provided on the mounting frame, and the two sewage collection parts are located on both sides of the sewage suction end of the sewage suction pipe 1. The two sewage collection parts are used to concentrate the silt at the sewage suction end of the sewage suction pipe 1 in a rotating manner during dredging.

[0024] Specifically, the two sewage collection parts have the same structure, including a rotating shaft 2 rotatably arranged on the mounting frame. One end of the rotating shaft 2 is connected to a driving motor 3, and a rotating cylinder 4 is sleeved on the rotating shaft 2. A sewage collection plate 5 is arranged on the rotating cylinder 4; during dredging, the driving motor 3 drives the rotating shaft 2 to rotate, driving the rotating cylinder 4 to rotate around the axis, and correspondingly driving the sewage collection plate 5 to rotate; the two sewage collection plates 5 rotate in opposite directions and abut against the bottom wall of the channel to push the silt from the side of the channel to the sewage suction end of the sewage suction pipe 1 for centralized suction, thereby improving the dredging efficiency.

[0025] The rotary drum 4 is a hollow cylindrical body structure, and the rotary drum 4 has an annular peripheral plate 41 and two opposite end plates 42; a cylindrical cavity is formed inside the rotary drum 4, and the rotary drum 4 is provided with shaft holes on the end plates 42 that communicate with the cylindrical cavity to facilitate the insertion of the rotating shaft 2, and the rotating shaft 2 is in interference fit with the shaft holes on the end plates 42, so that when the rotating shaft 2 rotates, it can drive the rotary drum 4 to rotate around the axis accordingly.

[0026] An expansion mechanism that can extend outside the rotary drum 4 to connect the sewage collection plate 5 is arranged in the cylindrical cavity inside the rotary drum 4. The expansion mechanism is used to keep the sewage collection plate 5 in contact with the bottom wall of the channel when pushing and sweeping the silt, so as to avoid silt residue and improve the dredging effect.

[0027] Specifically, the expansion mechanism includes a fixed sleeve 6 fixedly sleeved on the rotating shaft 2. One side of the fixed sleeve 6 is provided with a push plate 7 that can move radially along the rotary drum 4. The push plate 7 is provided with a connecting portion that can extend outside the rotary drum 4 to connect the sewage collection plate 5. The annular peripheral plate 41 of the rotary drum 4 is provided with a guiding channel for the connecting portion on the push plate 7 to extend. A spring 8 is connected between the fixed sleeve 6 and the push plate 7. The spring 8 is used to drive the push plate 7 to move towards the annular peripheral plate 41 of the rotary drum 4, so that the connecting portion on the push plate 7 can extend outside the rotary drum 4 and drive the sewage collection plate 5 to move away from the annular peripheral plate 41 of the rotary drum 4.

[0028] When the push plate 7 abuts against the inner wall of the annular peripheral plate 41 of the rotary drum 4, the distance between the push plate 7 and the fixed sleeve 6 is the largest, the spring 8 is in a stretched state, and the connecting portion on the push plate 7 extends outside the rotary drum 4. At this time, the distance between the sewage collection plate 5 and the rotary drum 4 is the largest.

[0029] When pushing and dredging, the sewage collection plate 5 abuts against the bottom wall of the channel and generates a reaction force, so that the sewage collection plate 5 moves towards the rotary drum 4. The distance between the sewage collection plate 5 and the rotary drum 4 decreases. Correspondingly, the connecting portion on the push plate 7 retracts inside the rotary drum 4, so that the push plate 7 separates from the inner wall of the annular peripheral plate 41 of the rotary drum 4 and moves towards the fixed sleeve 6. The distance between the push plate 7 and the fixed sleeve 6 decreases, and the spring 8 compresses to generate an elastic force, and this elastic force is used to keep the sewage collection plate 5 in contact with the bottom wall of the channel.

[0030] In this embodiment, the fixed sleeve 6 is a rectangular hollow sleeve structure with four flat outer sides. One end of the spring 8 is connected to one of the outer sides of the fixed sleeve 6, and the other end of the spring 8 is connected to the plate surface of the push plate 7 facing the fixed sleeve 6; in this embodiment, a plurality of springs 8 are provided, and the plurality of springs 8 are arranged at equal intervals along the length direction of the fixed sleeve 6.

[0031] In this embodiment, the push plate 7 is a long rectangular plate body, and the length direction of the push plate 7 is parallel to the axis of the rotary drum 4; the connecting parts on the push plate 7 are a plurality of cylindrical push rods 9. The plurality of push rods 9 are arranged on one surface of the push plate 7 facing the annular peripheral plate 41 of the rotary drum 4 and are spaced along the length direction of the push plate 7. The push rods 9 extend axially and extend out of the rotary drum 4 through the guiding channels provided on the annular peripheral plate 41 of the rotary drum 4 and are connected to the side edge of the sewage collecting plate 5; by providing a plurality of push rods 9, a plurality of force application points can be formed on one side of the sewage collecting plate 5, so that the sewage collecting plate 5 is more evenly stressed, effectively ensuring that the other side of the sewage collecting plate 5 away from the push rod 9 can be attached to the bottom wall of the channel during silt cleaning.

[0032] In this embodiment, the mounting frame includes a support plate 10. The sewage suction pipe 1 is connected to the support plate 10. One end of the sewage suction pipe 1 extends out of the top surface of the support plate 10 and is connected to the sewage suction pump provided on the silt cleaning vehicle. The other end of the sewage suction pipe 1 extends out of the bottom surface of the support plate 10 and bends to form a sewage suction end with an axis parallel to the plate surface of the support plate 10. A sewage suction nozzle 11 is provided at the sewage suction end of the sewage suction pipe 1. The sewage suction nozzle 11 is a conical nozzle body with a small proximal end and a large distal end, so as to expand the sewage suction range and improve the silt cleaning efficiency.

[0033] A connecting plate 12 for rotatably supporting the rotating shaft 2 is provided at the bottom of the support plate 10. A shaft hole that can be rotationally matched with the end of the rotating shaft 2 is provided on the connecting plate 12. The driving motor 3 is fixedly installed on the connecting plate 12 through a connecting frame 13 and is connected to one end of the rotating shaft 2.
