Description

Technical Field

[0001] This utility model relates to the technical field of pond fishing net retrieval equipment, and in particular to a traction device for retrieval of pond fishing nets. Background Technology

[0002] In pond aquaculture, harvesting is a crucial production step, and the traction device for setting and retrieving pond fishing nets is a key piece of equipment, its performance directly affecting the efficiency and quality of the harvesting operation. Traditional traction devices for setting and retrieving pond fishing nets have many drawbacks in practical applications, making it difficult to meet the high-efficiency and stable demands of modern pond aquaculture.

[0003] Traditional pond net retrieval systems typically employ two independent winches for operation. During setup, suitable installation locations must be found for each winch, considering not only spatial layout to prevent interference but also ensuring smooth connection to the nets and other related equipment. Furthermore, each winch requires individual fixing and debugging, involving the installation of multiple components and wiring connections, making the entire setup process complex, time-consuming, and labor-intensive. Additionally, some traction devices have fixed winch structures, limiting flexibility to adapt to specific needs. This makes it difficult to adapt to different rope specifications or changes in rope winding methods, leading to rope tangling and knotting during winding. This is because the rope lacks effective guidance and constraint, preventing it from winding in a neat and orderly fashion. Knotted ropes not only hinder retrieval but can also damage the rope, increasing operating costs and, in severe cases, requiring a halt to operations to address the knots, significantly reducing retrieval efficiency. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention aims to provide a traction device for setting and retrieving pond fishing nets, so as to solve the problems of inconvenient installation and adjustment of winch and easy knotting of rope in the existing traction devices, improve the efficiency and quality of pond fishing operations, and reduce labor intensity and operating costs.

[0005] To achieve the above objectives, this utility model proposes a traction device for setting and retrieving pond fishing nets, including a frame. Two take-up winches are arranged side by side on the frame. The two take-up winches are rotatably connected to the frame through rotating shafts. Both rotating shafts are equipped with drive motors, which can drive the corresponding rotating shafts to rotate, thereby driving the corresponding take-up winches to rotate.

[0006] The take-up winch includes two inner and outer discs arranged side by side. Both discs are slidably fitted onto corresponding rotating shafts, and an anti-rotation structure is provided between the two discs and the rotating shafts. The two discs are also separated by annular pads. An annular protrusion is integrally formed on the outer circle of the inner end of the rotating shaft. An open-type positioning ring is provided on the outer side of the take-up winch. The open-type positioning ring is movably fitted onto the rotating shaft and can be locked by a set screw. Thus, it can cooperate with the annular protrusion to lock and fix the inner and outer discs and the annular pads onto the rotating shaft through axial compression. A pull rope is also wound on the take-up winch. The diameter of the pull rope matches the axial length of the annular pads. A through hole is provided on one side of the disc of the take-up winch for the pull rope to pass through. After the inner end of the pull rope passes through the through hole, it is locked by a rope clamp, thus locking and fixing it onto the take-up winch.

[0007] In the above solution: the annular pad is equipped with various length specifications, and the annular pad of the corresponding length specification can be selected according to the diameter of the pull rope and installed on the rotating shaft, thereby adjusting the gap between the inner and outer discs so that the gap width matches the diameter of the pull rope. During the winding process, the pull rope can be wound outward in a neat and orderly manner, reducing the occurrence of pull rope confusion and knots.

[0008] In the above scheme: the frame includes a base plate and three vertical support plates spaced apart on the left and right sides above the base plate. Two winding winches are respectively arranged between two adjacent vertical support plates. Two drive motors are respectively fixed on the outer walls of the two end vertical support plates and connected to the corresponding rotating shafts. The structure is compact and the spatial layout is reasonable, avoiding mutual interference between components and improving the overall space utilization and operational stability of the device.

[0009] In the above solution: the take-up winch is equipped with a protective cover, which is fixed to the frame and has an opening and exit for the pull rope to pass through. The protective cover can effectively block foreign objects, such as branches and stones, to prevent them from being caught in the take-up winch during operation, thus avoiding jamming or damage to the winch due to interference from foreign objects; it can also isolate the take-up winch from the external environment, forming a relatively independent safety area, so that operators do not have to worry about being injured by accidentally touching the rotating take-up winch during operation.

[0010] In the above scheme, the entrances and exits of the two protective covers are staggered, one above the other. During pond net retrieval operations, the reeling in and releasing of the line often need to be done simultaneously; this staggered arrangement effectively prevents the two ropes from interfering with each other.

[0011] In the above solution: a guiding mechanism is provided at the entrance and exit of the protective cover. The guiding mechanism includes two rollers spaced apart vertically, and the pull rope passes through the gap between the two rollers. The guiding mechanism effectively guides the pull rope in an orderly manner, preventing the pull rope from tangling or knotting at the entrance and exit.

[0012] In the above scheme: the anti-rotation structure includes a groove on the rotating shaft and a limiting protrusion on the disc. The limiting protrusion is inserted into the groove to ensure that the disc can rotate synchronously with the rotating shaft.

[0013] The beneficial effects of this utility model are as follows: 1. The design of two winches arranged side by side on the left and right, sharing a common frame, greatly saves space and reduces the difficulty of equipment installation and site planning compared to the traditional arrangement of two independent winches. 2. The inner and outer discs of the winch slide on the rotating shaft and are axially pressed and locked in place by an open-type positioning ring and an annular protrusion. This design allows the winch to be flexibly adjusted according to actual usage needs. When dealing with different specifications of pull ropes, the winch structure can be better adapted to the pull rope by replacing the annular pads with different axial lengths. This effectively avoids the problem of the winch structure being unable to adapt to different pull rope specifications. The pull rope diameter matches the axial length of the annular pad, and during the winding process, the pull rope can be wound outwards in a neat and orderly manner, reducing the occurrence of pull rope tangling and knots, ensuring the smooth progress of the capture operation, and reducing the risk of pull rope damage. 3. The inner end of the pull rope passes through the hole on the disc and is locked in place by the rope clamp. This design provides effective fixation for the inner end of the pull rope, which helps to ensure the stability of the entire device. Attached Figure Description

[0020] like Figure 1 As shown in Figure 6, a traction device for releasing and retrieving fishing nets in ponds mainly consists of a frame 1 and two winches 2 arranged side by side on the frame 1.

[0021] Two take-up winches 2 are rotatably connected to the frame 1 via rotating shafts 3. Both rotating shafts 3 are equipped with drive motors 4, which can drive the corresponding rotating shafts 3 to rotate, thereby driving the corresponding take-up winches 2 to rotate.

[0022] Specifically, the frame 1 includes a base plate and three vertical support plates spaced apart on the left and right sides above the base plate. Two winding winches 2 are respectively arranged between two adjacent vertical support plates. Two drive motors 4 are respectively fixed on the outer walls of the two end vertical support plates and connected to the corresponding rotating shafts 3. The structure is compact and the spatial layout is reasonable, avoiding mutual interference between components and improving the overall space utilization and operational stability of the device.

[0023] The winding reel 2 includes two inner and outer discs 21 arranged side by side. Both discs 21 are slidably mounted on corresponding rotating shafts 3, and an anti-rotation structure is provided between the two discs 21 and the rotating shafts 3. The anti-rotation structure includes a groove 31 formed on the rotating shaft 3 and a limiting protrusion 22 arranged on the discs 21. The limiting protrusion 22 is inserted into the groove 31 to ensure that the discs 21 can rotate synchronously with the rotating shaft 3.

[0024] The two discs 21 are separated by an annular pad 5. An anti-rotation structure is also provided between the annular pad 5 and the rotating shaft 3. An annular protrusion 6 is integrally formed on the outer circle of the inner end of the rotating shaft 3. An open-type positioning ring 7 is provided on the outer side of the winding winch 2. The open-type positioning ring 7 is movably sleeved on the rotating shaft 3 and can be locked by a set screw. Thus, it can cooperate with the annular protrusion 6 to lock and fix the inner and outer discs 21 and the annular pad 5 on the rotating shaft 3 through axial compression.

[0025] A pull rope is also wound on the take-up winch 2. The diameter of the pull rope matches the axial length of the annular pad 5. One side disc 21 of the take-up winch 2 has a through hole for the pull rope to pass through. After the inner end of the pull rope passes through the through hole, it is locked by the rope clamp 8, thus locking it to the take-up winch 2. Specifically, the inner end of the pull rope passes through the rope clamp and is knotted, and then the bolt of the rope clamp is tightened to clamp the pull rope.

[0026] The annular pad 5 is available in various lengths, allowing the selection of the appropriate length of annular pad 5 to be installed on the rotating shaft according to the diameter of the pull rope. This adjusts the gap between the inner and outer discs 21, ensuring that the gap width matches the diameter of the pull rope. During the winding process, the pull rope can be wound outward in a neat and orderly manner, reducing the occurrence of rope tangling and knotting.

[0027] The take-up winch 2 is equipped with a protective cover 9, which is fixed to the frame 1 and has an opening and exit for the pull rope to pass through. The protective cover 9 can effectively block foreign objects, such as branches and stones, to prevent them from being caught in the take-up winch 2 during operation, thus avoiding jamming or damage to the take-up winch 2 due to interference from foreign objects; it can also isolate the take-up winch 2 from the external environment, forming a relatively independent safety area, so that operators do not have to worry about being injured by accidentally touching the rotating take-up winch 2 during operation.

[0028] The entrances and exits of the two protective covers 9 are staggered, one above the other. In pond fishing net retrieval operations, the retrieval and release of lines often need to be carried out simultaneously, and this staggered arrangement can effectively avoid interference between the two ropes.

[0029] The protective cover 9 has a guide mechanism 10 at its entrance and exit. The guide mechanism 10 includes two rollers spaced apart vertically, through which the pull rope passes. The guide mechanism effectively guides the pull rope in an orderly manner, preventing it from tangling or knotting at the entrance and exit.
