Description

Technical Field

[0001] This utility model belongs to the field of fishpond dredging technology, specifically relating to a fishpond dredging device. Background Technology

[0002] Currently, in fishpond dredging operations, traditional dredging devices typically only have a single grid or filter screen at the sludge inlet to prevent large impurities in the sludge from entering the pump body and affecting its safe dredging operation. During the sludge suction process, stubborn sludge that is difficult to remove easily adheres to the outside of these devices, and impurities easily accumulate on the inside, causing blockages. Furthermore, they lack a linkage structure for real-time cleaning. Once a blockage occurs, the machine must be stopped and the device manually disassembled and cleaned. This not only frequently interrupts the operation process and significantly reduces dredging efficiency, but also increases the workload of operators. It is difficult to meet the continuous dredging needs of different areas of the fishpond. Due to its poor ease of use and unstable operating efficiency, the widespread application of these devices in actual dredging scenarios is limited. Utility Model Content

[0003] In view of the above problems, the purpose of this utility model is to provide a fishpond dredging device to solve the problems mentioned above.

[0004] To achieve the above objectives, a fishpond dredging device includes a dredging pipe and a fixed pipe head. One end of the dredging pipe is provided with a fixed ring, which is connected to the dredging pipe via a protective railing A. A protective railing B is installed on the inner wall of the fixed ring. One end of the dredging pipe is rotatably connected to a rotating ring. Several outer sliding rings are slidably connected to the outer sides of the protective railings A. Scrapers offset from the protective railings A are installed on the inner walls of the outer sliding rings. Several inner sliding rings are slidably connected to the inner sides of the protective railings A. Push plates offset from the protective railings B are installed on the inner walls of the inner sliding rings. An L-shaped push rod is installed on the outer wall of the outer sliding rings. A fixed frame is installed on the rotating ring. Support frames are installed between the fixed frames. Connecting frames are installed between the fixed frames. The L-shaped push rod is slidably connected to the connecting frame.

[0005] Preferably, an annular plate is installed on the outer wall of one end of the suction pipe, and an annular groove matching the annular plate is opened on the inner wall of the rotating ring. Both the annular groove and the annular plate are annular in shape.

[0006] Preferably, a slide rod A is slidably connected to the inner wall of the support frame, and one end of the L-shaped push rod passes through the slide rod A.

[0007] Preferably, a slide rod B is slidably connected to the inner wall of the support frame, and the slide rod A and the slide rod B are connected by a connecting rod.

[0008] Preferably, the inner wall of the outer slip ring is fitted with a bracket that is offset from the guardrail A, and the bracket is connected to one end of the inner slip ring.

[0009] This utility model has the following beneficial effects: The device forms a double anti-clogging structure by having a scraper on the inner wall of the outer slip ring that is misaligned with guardrail A, and a pusher on the inner wall of the inner slip ring that is misaligned with guardrail B. During operation, pushing the L-shaped push rod can cause the outer slip ring to slide along the outside of guardrail A. The scraper can scrape away the stubborn sludge attached to the surface of guardrail A in real time, preventing the outer channel from being blocked. At the same time, the inner slip ring slides along the inside of guardrail A in conjunction with the outer slip ring. The pusher can push away the sludge accumulated on the inside of guardrail B, preventing the inner filter structure from being blocked. This ensures that the sludge can continuously enter the fixed ring through the gap between guardrail A and guardrail B, solving the problem that traditional dredging devices are prone to reduced suction efficiency due to clogging.

[0012] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0013] Example 1: As Figure 1As shown in Figure 4: This utility model provides the following technical solution: It includes a sludge suction pipe and a fixed pipe head. One end of the sludge suction pipe is provided with a fixed ring. The fixed ring and the sludge suction pipe are connected by a protective railing A. A protective railing B is installed on the inner wall of the fixed ring. One end of the sludge suction pipe is rotatably connected to a rotating ring. Several outer sliding rings are slidably connected to the outer sides of the protective railing A. A scraper that is offset from the protective railing A is installed on the inner wall of the outer sliding ring. Several inner sliding rings are slidably connected to the inner sides of the protective railing A. A push plate that is offset from the protective railing B is installed on the inner wall of the inner sliding ring. An L-shaped push rod is installed on the outer wall of the outer sliding ring. A fixed frame is installed on the rotating ring. A support frame is installed between the fixed frames. A connecting frame is installed between the fixed frames. The L-shaped push rod is slidably connected to the connecting frame.

[0014] In this implementation plan: a fixing ring is installed at one end of the sludge suction pipe. The fixing ring and the sludge suction pipe are fixedly connected by several evenly distributed ring-shaped protective railings A. The protective railings A are made of stainless steel, which ensures structural strength and prevents large impurities in the sludge from directly clogging the sludge suction channel. Several parallel protective railings B are welded to the inner wall of the fixing ring. The protective railings B are perpendicularly staggered with the protective railings A, further filtering large impurities in the sludge and allowing the sludge to effectively pass through the gaps between the protective railings A and B. The sludge is extracted by placing a fixed pipe head at one end of the sludge suction pipe inside the sludge. A rotating ring is rotatably connected to the end of the sludge suction pipe near the fixed ring. Several outer sliding rings are slidably connected to the outer sides of several guardrails A. Several scrapers, made of wear-resistant rubber and with the same length as guardrails A, are welded to the inner wall of the outer sliding ring and slide along the guardrails A. An inner sliding ring is slidably connected to the inner sides of several guardrails A, and its inner wall is welded to be offset from the guardrails B. The push plate, a thin-plate structure, slides along the inner side of several guardrails A along the inner slip ring. An L-shaped push rod is welded to the outer wall of the outer slip ring. The horizontal section of the L-shaped push rod extends to the outer side of the rotating ring. Two fixing frames are welded to the outer wall of the rotating ring, and a support frame and a parallel connecting frame are welded between the fixing frames. The horizontal section of the L-shaped push rod passes through the connecting frame and slides in cooperation with it. The user can easily adjust the position of the fixing ring at one end of the sludge suction pipe by holding the support frame. The fixing pipe end is connected to the inlet pipe of an external sludge suction pump. The device is placed with one side of the fixing ring... After starting the sludge pump in the silt at the bottom of the fishpond, the L-shaped push rod can be pushed during operation to move the outer and inner slip rings along guardrail A. When the scraper on the outer slip ring slides, it can scrape off the silt that is difficult to pump out on the outside of guardrail A, preventing silt from accumulating and blocking the channel. When the pusher on the inner slip ring slides, it can push the silt on the inside of guardrail B, preventing blockage at guardrail B. This allows the silt to pass through guardrails A and B and enter the fixed ring for pumping, while preventing guardrails A and B from getting blocked, thus improving the silt pumping efficiency.

[0015] An annular plate is installed on the outer wall of one end of the suction pipe. An annular groove matching the annular plate is formed on the inner wall of the rotating ring. Both the annular groove and the annular plate are annular in shape. An annular plate is fixedly installed on the outer wall of one end of the suction pipe by welding. An annular groove matching the size of the annular plate is formed on the inner wall of the rotating ring along its circumference. Both the annular plate and the annular groove are closed annular structures. The annular plate can be embedded in the annular groove and slide along the circumference of the groove. The outer diameter of the annular plate and the inner diameter of the annular groove are fitted with a clearance fit. This ensures that the rotating ring can rotate flexibly around the suction pipe, while limiting the displacement of the rotating ring along the axial direction of the suction pipe, preventing the rotating ring from falling off the suction pipe. During operation, when the operator holds the support frame and the position of the suction pipe changes, the rotating connection between the rotating ring and the suction pipe facilitates the dragging and displacement of the suction pipe.

[0016] The inner wall of the support frame is slidably connected to a slide rod A, and one end of the L-shaped push rod passes through the slide rod A. The support frame is a U-shaped frame structure, and its inner wall has a rectangular slide groove along its length. The slide rod A is a cuboid metal rod, the size of which matches the rectangular slide groove of the support frame, and it can slide along the length of the slide groove. One end of the vertical section of the L-shaped push rod passes through the central through hole of the slide rod A, and the two are in transition fit. When the support frame is held, the slide rod A is pushed, thereby pushing the L-shaped push rod to move, so that the L-shaped push rod slides horizontally on the connecting frame, and the L-shaped push rod pushes the outer slip ring to move.

[0017] The inner wall of the support frame is slidably connected to a slide rod B, and the slide rod A and the slide rod B are connected by a connecting rod. On the inner wall of the support frame, a connecting rod is welded to the slide rod B, so that the slide rod A and the slide rod B form an integral frame, which is convenient to push the frame to adjust the position of the L-shaped push rod.

[0018] The inner wall of the outer slip ring is equipped with a bracket that is offset from the guardrail A. The bracket is connected to one end of the inner slip ring. On the inner wall of the outer slip ring, the position of the bracket is offset from the guardrail A to avoid interference with the guardrail A. The end of the bracket away from the outer slip ring is fixedly connected to the outer wall of the inner slip ring by welding, so that the outer slip ring, the bracket and the inner slip ring form a linkage whole.

[0019] The working principle of this technical solution is as follows: During operation, the operator holds the support frame and places the fixed ring end into the area of ​​the fishpond to be dredged, adjusting it to contact the silt layer. After starting the dredging pump, if the suction efficiency decreases, the sliding rod A can be pushed to drive the L-shaped push rod to slide, so that the outer and inner sliding rings move along the outer and inner sides of the guardrail A, respectively. The blockage is cleared by the scraper and push plate. The fixed ring orientation can also be adjusted to cover different areas by using the rotation of the dredging pipe and the rotating ring to drag the device. After the operation is completed, the dredging pump is turned off and the connection between the fixed pipe head and the dredging pump is disconnected. The device is taken out by holding the support frame, the residual silt and impurities are cleaned, and the outer and inner sliding rings are reset after checking the integrity of the parts.
