Description

Technical Field

[0001] The utility model relates to the technical field of aquatic fishing equipment, in particular to an automatic cage-retracting and -releasing device for catching crayfish. Background Art

[0002] Crayfish, scientifically known as Procambarus clarkii, are a commercial freshwater shrimp species. Crayfish farming employs a variety of methods. Ground traps are commonly used for catching crayfish. Ground traps are highly efficient, featuring multiple entrances for easy entry and difficult exit. They can capture large numbers of crayfish within their habitats and offer selective capture. Adjusting the mesh size allows for controlled capture, facilitating sustainable resource utilization and improving aquaculture profitability. They are simple and flexible to operate, minimally damaging to the crayfish, and widely applicable in various waters. They are also easy to retrieve and guarantee high-quality crayfish.

[0003] The ground trap fishing device mainly consists of a frame, a net, an entrance, and a tail. The frame plays a supporting role and is made of metal or plastic; the net is the main part and is made of materials such as polyethylene, and the mesh size can be selected as needed. There are multiple entrances, which are funnel-shaped, with a large outer opening and a small inner opening, which makes it easy for crayfish to enter but difficult to exit. The tail is used to collect crayfish and has an opening or a detachable net bag. Its working principle is to place the ground trap in the water and take advantage of the crayfish's tendency to flow, avoid light, and foraging habits to allow the crayfish to enter the ground trap through the entrance. Due to the special design of the entrance, they are trapped in the cage and finally removed through the tail.

[0004] In the existing technology, the placement of ground cages must be flexible and accurate, and manpower can adjust the placement of ground cages according to the terrain. However, ground cages are often heavy, resulting in high labor costs and low efficiency in laying ground cages manually. Especially when fishing in large areas of water, it will take a lot of time and manpower, and manual laying is dangerous. Therefore, an automatic cage retracting and releasing device for crayfish fishing is proposed to solve the above problems. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figures 1 to 3 The utility model provides an embodiment: an automatic cage-folding and releasing device for catching crayfish, comprising a ground pile 1 and a ground pile 2 2. Ground pile 1 and ground pile 2 2 play a basic role in fixing the entire device, providing reliable support points for the subsequent installation and operation of various components, ensuring that the entire device will not easily shake or shift during use. The tops of ground pile 1 and ground pile 2 2 are fixedly connected to two support columns 5, which play the role of connecting and supporting subsequent structures. The outer wall of the support column 5 is fixedly connected with a steel rope 6. The steel rope 6 is mainly used to further strengthen the overall structural stability of the device, and can also share the force of pile 1 and ground pile 2 2 to a certain extent. The other end of the steel rope 6 is detachably connected to a ground nail 7. The function of the ground nail 7 is to penetrate deep into the ground, further enhance the firmness of the connection between the entire device and the ground, prevent the device from loosening due to external forces during operation, and ensure that the entire device maintains a stable working state when in use. The bottoms of the two ground nails 7 are fixedly connected to the driving mechanism, the outer walls on both sides of the ground pile 1 are fixedly connected to the transmission mechanism, and the outer walls of the transmission mechanism are detachably connected to the ground cage mechanism.

[0033] The driving mechanism includes a sliding table 8, the top of which is fixedly connected to the bottom of two ground nails 7. The sliding table 8 provides an installation base and a reference surface for movement for subsequent components. The outer wall of the sliding table 8 is fixedly connected to an electric push rod 9, and the output end of the electric push rod 9 is fixedly connected to a driving table 10. The electric push rod 9 can perform telescopic movements according to the control signal, thereby driving the driving table 10 to perform corresponding linear motion. The bottom of the driving table 10 is slidably connected to the top of the sliding table 8. The driving table 10 is used to drive the subsequent fishing structure to perform fishing operations, and at the same time, the tightness of the subsequent structure is adjusted by the movement of the driving table 10.

[0034] The outside of the driving platform 10 is provided with a motor 11, and the output end of the motor 11 is fixedly connected to a rotating column 12. The outer wall of the rotating column 12 is rotatably connected to the inside of the driving platform 10. When the motor 11 is working, it will generate a rotating power, driving the rotating column 12 to rotate. The rotating column 12 can flexibly rotate around its own axis inside the driving platform 10, ensuring that the power output by the motor 11 can be effectively transmitted to subsequent components and will not cause problems such as jamming due to connection problems. The outer wall of the rotating column 12 is fixedly connected to two driving wheels 13, and the outer side of the driving wheel 13 is coupled to a steel rope 2 14. When the rotating column 12 rotates under the drive of the motor 11, the driving wheel 13 also rotates synchronously. Due to the coupling connection relationship between the driving wheel 13 and the steel rope 2 14, the rotation of the driving wheel 13 can drive the steel rope 2 14 to perform corresponding movements.

[0035] The transmission mechanism includes two fixed pulleys 16, each rotatably connected to one side of the ground pile 1. The outer wall of the second steel rope 14 is coupled to the outer side of the fixed pulleys 16. The fixed pulleys 16 are used to change the direction of the second steel rope 14, thereby ensuring that the second steel rope 14 can stably perform its transmission function and effectively transmit power to the ground trap, ensuring that the ground trap's movement meets the requirements of the fishing process. Two transmission wheels 17 are rotatably connected to each side of the ground pile 1. The outer wall of the second steel rope 14 is coupled to the outer side of the transmission wheel 17. The transmission wheel 17 functions to change the direction of the movement of the second steel rope 14 and assist in power transmission.

[0036] A jack 3 is fixedly connected to the interior of ground pile 2. A driving power source is provided on the exterior of jack 3 for driving jack 3 to perform a lifting operation. As a device capable of performing a lifting function, jack 3 plays a role in height adjustment within the entire device. The output end of jack 3 is fixedly connected to a lifting platform 4. When jack 3 is in operation, the expansion and contraction of its internal structure can drive lifting platform 4 to rise or fall, thereby changing the relative height and angle of steel rope 2 14, thereby achieving control over the lobster fishing process. The outer wall of lifting platform 4 is slidably connected to the inner wall of ground pile 2, thereby ensuring that lifting platform 4 can maintain a relatively stable state at different heights. Two transmission wheels 2 18 are rotatably connected to each side of lifting platform 4. The outer wall of steel rope 2 14 is coupled to the outer side of transmission wheel 2 18. The relative motion of transmission wheel 2 18 and transmission wheel 1 17 allows the ground trap to move along the desired trajectory, facilitating the completion of fishing-related actions such as lowering, lifting, and retracting.

[0037] Reference Figures 2 to 4 The cage mechanism includes multiple locking rings 19, the inner walls of which are detachably connected to the outer walls of the two steel ropes 14. The locking rings 19 securely connect the cage to the steel ropes 14, ensuring that the cage does not fall off the steel ropes 14 during movement. A connecting post 20 is fixedly connected to the bottom of the locking rings 19, and the bottoms of the two connecting posts 20 are fixedly connected to an outer frame 24. The connecting posts 20 firmly connect the locking rings 19 and the outer frame 24 together, transmitting force and maintaining structural integrity. This allows the various components of the cage to work together to ensure the cage's shape and structural stability in water. A cage net 25 is fixedly connected to the adjacent side of the two outer frames 24. The cage net 25 cooperates with the outer frame 24 to form a solid ground cage structure. The outer frame 24 ensures that the cage net 25 maintains a suitable shape in the water, making it easy for crayfish to enter the ground cage smoothly and not easily escape. The cage net 25 is the part directly used to catch crayfish. The mesh size is carefully designed to allow crayfish to enter smoothly while preventing them from easily drilling out. It also has a certain degree of flexibility and strength, can adapt to the complex environment in the water, and is not easily damaged even after being soaked in water for a long time, thereby ensuring the fishing effect of the ground cage.

[0038] The internal thread of the locking ring 19 is connected to a stud 21. The stud 21 is threadedly connected to the locking ring 19, and can be loosened or tightened when rotated. The outer wall of the stud 21 is fixedly connected to two support plates 22. The adjacent sides of the two support plates 22 are rotatably connected to a cam 23, and the support plates 22 provide a stable installation position for the cam 23. The bottom of the cam 23 contacts the top of the stud 21. The cam 23, through its special shape and contact relationship with the stud 21, plays a role in limiting and controlling the rotation of the stud 21. Only when the cam 23 rotates to a specific position so that its protruding part is separated from the stud 21, can the stud 21 rotate smoothly, thereby further ensuring the connection firmness of the cage during normal use and the controllability of the operation when disassembly is required.

[0039] The cage head of the cage net 25 is fixedly connected to a connecting plate 26 via multiple traction ropes. The cage head of the cage is where crayfish tend to gather during the cage lifting process. The traction ropes connect the cage head to the connecting plate 26, ensuring that the cage head can remain relatively stable during operations such as lifting the cage. The other end of the connecting plate 26 is fixedly connected to a hanging rope 27. The tops of the ground piles 1 and 2 are respectively fixedly connected to two top plates 28. The adjacent sides of the two top plates 28 are fixedly connected to a steel rope 3 29. Steel rope 3 29 and steel rope 2 14 cooperate with each other to stabilize the cage and guide its movement during the cage lifting process. The outer wall of the steel rope 3 29 is covered with multiple sliding rings 15. The tops of the hanging ropes 27 are detachably connected to the inside of the sliding rings 15. During the cage lifting process, the connection between the hanging ropes 27 and the sliding rings 15 can further stabilize the cage's movement, preventing the cage from shaking significantly, making it easy to smoothly pull the cage into the appropriate position and facilitate subsequent crayfish collection.

[0040] Working principle: When in use, the jack 3 is operated to drive the lifting platform 4 to descend so that the lifting platform 4 is flush with the ground pile 1, thereby keeping the steel rope 2 14 and the ground cage level, and then start the electric push rod 9. The electric push rod 9 operates to drive the driving platform 10 to move linearly on the sliding platform 8. When the driving platform 10 moves closer to the ground pile 1, the steel rope 2 14 loosens, and thus moves downward by the dead weight of the ground cage, so that the ground cage is completely immersed in water, thereby performing the net laying and fishing operation. After a period of time, the electric push rod 9 operates in the opposite direction to make the driving platform 10 away from the ground pile 1, thereby tightening the steel rope, thereby pulling up the ground cage, and then the jack 3 is used to make the lifting platform 4 rise, so that the steel rope 2 14 and the steel rope 3 29 tilt toward the ground pile 1. , then turn on the motor 11. The operation of the motor 11 drives the rotating column 12 to rotate, thereby driving the driving wheel 13 to rotate, thereby driving the steel rope 2 14 to rotate toward the ground pile 1, thereby driving the ground cage to move and shrink toward the ground pile 1, so that the crayfish in the ground cage are shaken to the cage head of the ground cage, and the sliding ring 15 stabilizes the movement of the ground cage on the steel rope 3 29. At this time, the staff can remove the hanging rope 27 from the sliding ring 15, and then rotate the cam 23 to separate the protruding part of the cam 23 from the stud 21, so that the stud 21 can rotate, and then rotate the stud 21 to loosen the locking ring 19, and then the entire ground cage can be taken out by removing the locking ring 19. At this time, the crayfish gather at the cage head to facilitate collection.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
