Description

Technical Field

[0001] This utility model relates to the field of aquatic product harvesting and transfer equipment technology, and in particular to a rapid harvesting and transfer device for yellow croaker. Background Technology

[0002] In fisheries production, the harvesting and transfer of yellow croaker directly impacts operational efficiency, fish survival rate, and economic benefits. Traditional methods of harvesting and transferring yellow croaker have many shortcomings. Harvesting equipment relies heavily on manual guidance of fish into the nets, and it is difficult to quickly gather the fish after harvesting, resulting in long harvesting times and low efficiency. Yellow croaker are also prone to escape during the process. During the transfer phase, excess water cannot be effectively managed, increasing transportation load and energy consumption. Furthermore, there is a lack of fish protection measures, and rough handling can easily cause fish to be crushed and scratched, reducing survival rate and quality. In addition, traditional equipment has limited functionality and cannot meet the integrated operation requirements of harvesting, sorting, and storage. The operation process is cumbersome, requires high skill levels from operators, and involves high labor intensity. With the development of the fisheries industry towards large-scale and efficient operations, a new type of harvesting and transfer device is needed to solve the above problems, improve the overall efficiency of yellow croaker harvesting and transfer, and ensure the sustainable use of fishery resources and economic benefits.

Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0004] Therefore, the purpose of this utility model is to provide a rapid fishing and transfer device for yellow croaker, which can solve the existing problems of reducing fish damage and loss and meeting diverse operational needs.

[0005] To solve the above technical problems, this utility model provides a rapid yellow croaker fishing and transfer device, which adopts the following technical solution: it includes a transfer bucket, a fixed shaft is fixedly connected to the left and right ends of the transfer bucket, a first limiting member is fixedly connected to the outer surface of the fixed shaft, a rotating disk is rotatably connected to the outer surface of the fixed shaft, the inner side of the first limiting member is tightly fitted with the rotating disk, an installation plate is fixedly connected to the upper surface of the transfer bucket, a first fixing plate is fixedly connected to the upper surface of the left end of the installation plate, a folding net is provided at the upper end of the first fixing plate, a second fixing plate is fixedly connected to the end of the folding net away from the installation plate, and a quick-locking mechanism is provided inside the second fixing plate; The folding net includes a net cover, a mounting frame, and connectors; The quick-lock mechanism includes a connector, a guide rod, a lever, and a limit block.

[0006] Optionally, the transfer bucket is semi-circular and hollow, and the side wall of the transfer bucket is provided with drainage holes.

[0007] Through the above technical solution: in drainage mode, the drainage hole utilizes gravity and water pressure difference to quickly discharge the water flow during the transfer process, reducing the load on the device, avoiding increased transportation energy consumption due to excessive moisture, and meeting the water control requirements in different operating scenarios.

[0008] Optionally, the transfer bucket has a slot inside its side wall, and a plate is inserted into the inner wall of the slot.

[0009] The above technical solution enables the separation of the inner and outer spaces of the transfer bucket when the insert plate is inserted into the slot.

[0010] Optionally, the inner wall of the mounting frame is fixedly connected to the net, and the two sides of the mounting frame are fixedly connected to the connectors, with connecting rings provided between the connectors.

[0011] The above technical solution effectively prevents yellow croakers from escaping by using a net and a mounting frame.

[0012] Optionally, a second limiting member is fixedly connected to the connector at the outermost front end of the mounting frame, and a hole is provided on the outer side of the rotating disk, with the front end of the second limiting member passing through the hole and extending to the outside.

[0013] Through the above technical solution, the tilt angle of the folding net can be precisely adjusted by adjusting the engagement position of the second limiting component and the hole after the fishing is completed, thus precisely controlling the rotation angle of the folding net.

[0014] Optionally, the inner wall of the second fixing plate is slidably connected to the guide rod, the upper end of the guide rod is fixedly connected to a handle, and a spring is sleeved on the outside of the guide rod, with the upper and lower ends of the spring tightly fitted to the handle and the second fixing plate, respectively.

[0015] The above technical solution involves rotating the handle to move the guide rod up and down, compressing or releasing the spring, thereby enabling the insertion and disengagement of the limiting block from the limiting hole of the mounting plate. This allows for quick locking or unlocking of the folding net, making the operation simple and effectively preventing the yellow croaker from escaping after being caught, thus ensuring the success of the catch.

[0016] Optionally, the mounting plate has a limiting hole inside, and the lower end of the guide rod is fixedly connected to a limiting block, with the lower end of the limiting block slidably connected to the limiting hole.

[0017] Through the above technical solution, the sliding of the limiting block within the limiting hole provides precise guidance for the movement of the guide rod, ensuring the accuracy of the quick-lock mechanism during locking and unlocking, and preventing misoperation.

[0018] Optionally, a third limiting member is fixedly connected to the outer surface of the fixed shaft. There are two third limiting members, which are symmetrically distributed. A connecting rod is provided between the third limiting members. The front end and the rear end of the connecting rod are respectively tightly fitted with the third limiting member. A hanging rod is fixedly connected to the upper end of the connecting rod.

[0019] The above technical solution, through the suspension structure composed of a fixed shaft, a third limiting component, a connecting rod, and a suspending rod, allows the entire device to be quickly and stably suspended at a suitable position on a fishing vessel or work platform.

[0020] In summary, this utility model has at least one of the following beneficial effects: 1. Improved fishing efficiency: The semi-circular hollow transfer bucket design facilitates the guidance of yellow croakers into the bucket through manual driving or natural water flow, allowing for the capture of a large number of yellow croakers at once. It can also select between drainage mode and water retention mode according to fishing needs. In drainage mode, gravity and water pressure difference are used to quickly drain the water, reducing the load on the device and facilitating rapid transfer. The water retention mode is suitable for scenarios where it is necessary to maintain the aquatic environment for fish survival. It can meet the fishing and transfer needs under different conditions and improve the overall fishing and transfer efficiency.

[0021] 2. Simple and safe operation: The structural design of the device makes it relatively easy to operate. After the staff climbs onto the work platform, they can easily switch between drainage and water retention modes, as well as hoist and fish. At the same time, the quick-lock mechanism can lock and unlock the folding net by rotating the handle, which is convenient and quick to operate. In addition, the slow displacement of the device can prevent accidental injury to people due to the rapid closing when the folding net is rotating, thus reducing the danger.

[0026] Reference Figure 1-5 This utility model provides a rapid croaker fishing and transfer device, which includes a transfer bucket 1. A fixed shaft 18 is fixedly connected to the left and right ends of the transfer bucket 1. A first limiting member 17 is fixedly connected to the outer surface of the fixed shaft 18. A rotating disk 15 is rotatably connected to the outer surface of the fixed shaft 18. The inner side of the first limiting member 17 is tightly fitted with the rotating disk 15. An installation plate 2 is fixedly connected to the upper surface of the transfer bucket 1. A first fixing plate 3 is fixedly connected to the upper surface of the left end of the installation plate 2. A folding net 4 is provided at the upper end of the first fixing plate 3. A second fixing plate 5 is fixedly connected to the end of the folding net 4 away from the installation plate 2. A quick-locking mechanism is provided inside the second fixing plate 5.

[0027] The transfer bucket 1 is semi-circular and hollow. The side wall of the transfer bucket 1 is provided with a drainage hole 7. The inside of the side wall of the transfer bucket 1 is provided with a slot 6. The inner wall of the slot 6 is fitted with a plate 8. The outer surface of the fixed shaft 18 is fixedly connected with a third limiting member 20. There are two third limiting members 20 and they are symmetrically distributed. A connecting rod 21 is provided between the third limiting members 20. The front end and the rear end of the connecting rod 21 are tightly fitted with the third limiting member 20 respectively. The upper end of the connecting rod 21 is fixedly connected with a hanging rod 9.

[0028] The folding net 4 includes a net 10, a mounting frame 11, and a connector 12. The inner wall of the mounting frame 11 is fixedly connected to the net 10, and the two sides of the mounting frame 11 are fixedly connected to the connector 12. A connecting ring 13 is provided between the connectors 12. A second limiting member 19 is fixedly connected to the connector 12 at the outermost front end of the mounting frame 11. A hole 16 is provided on the outer side of the rotating disk 15. The front end of the second limiting member 19 passes through the hole 16 and extends to the outside.

[0029] The quick-lock mechanism includes a connector 12, a guide rod 24, a handle 22, and a limiting block 14. The inner wall of the second fixing plate 5 is slidably connected to the guide rod 24. The upper end of the guide rod 24 is fixedly connected to the handle 22. A spring 23 is sleeved on the outside of the guide rod 24. The upper and lower ends of the spring 23 are tightly fitted to the handle 22 and the second fixing plate 5, respectively. A limiting hole 25 is provided inside the mounting plate 2. The lower end of the guide rod 24 is fixedly connected to the limiting block 14. The lower end of the limiting block 14 is slidably connected to the limiting hole 25.

[0030] Working principle: After the staff climbs onto the work platform, they select the drainage mode according to the fishing needs. In the water retention mode, the insert plate 8 is inserted into the slot 6 on the side wall of the transfer tank 1. The sealing cooperation between the insert plate 8 and the drainage hole 7 prevents water from leaking out. This is suitable for scenarios where it is necessary to maintain the aquatic environment for fish survival. In the drainage mode, the insert plate 8 is removed so that the drainage hole 7 can be connected to the outside. During the transfer, gravity and water pressure difference are used to make the water flow out quickly, reducing the load on the device. Then, the device is hoisted to the work position by the suspension structure composed of the third limiting part 20 on the outer surface of the fixed shaft 18, the connecting rod 21, and the hanging rod 9.

[0031] After the yellow croaker school is discovered, the staff operates the device to immerse the transfer bucket 1 in the water. The semi-circular hollow transfer bucket 1 guides the yellow croaker into the bucket by manual driving or natural water flow. When the catch reaches the expected amount, the second fixing plate 5 is pulled. The second fixing plate 5 drives the connecting piece 12 to move, which in turn drives the mounting frame 11 to rotate around the rotating disk 15 as the axis, so that the net 10 rotates synchronously with the mounting frame 11. When the second fixing plate 5 is in contact with the mounting plate 2, the handle 22 is rotated to drive the guide rod 24 to move down and compress the spring 23, so that the limiting block 14 is inserted into the limiting hole 25 of the mounting plate 2, which firmly locks the folded net 4 to prevent the yellow croaker from escaping.

[0032] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
