Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, in particular to a crab breeding box for muddy beach. Background Art

[0002] As a popular seafood product, mud crabs are favored by consumers for their delicious meat and rich nutrition. With the continuous growth of market demand, mud crab farming has gradually emerged and become an important economic pillar in many coastal areas. However, traditional mud crab farming methods face many challenges, which limit the further development of the farming industry.

[0003] Traditional breeding boxes are mostly built with materials such as metal or wood, which not only has high material costs but also a complicated construction process, resulting in high overall construction costs. Due to the particularity of beach mud, traditional breeding boxes often require a lot of manpower and material resources when laid out, and are difficult to move, which is not conducive to the flexible layout and adjustment of breeding boxes. Traditional breeding boxes on beach mud are easily affected by natural factors such as wind, waves, and tides, resulting in an unstable breeding environment, affecting the growth and survival rate of crabs. Traditional breeding boxes have limited internal space and lack convenient observation and management facilities, making it difficult for breeders to grasp the growth status of crabs in real time, resulting in low management efficiency.

[0004] Therefore, a beach mud crab breeding box is needed to solve the shortcomings of traditional breeding boxes in terms of cost, layout, stability, management efficiency and resource utilization. Summary of the invention

[0005] In order to solve the problems of the prior art, the invention provides a crab breeding box in muddy beach.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] A crab breeding box for muddy beach, comprising:

[0008] A fixing plate, on which a fixing anchor placement opening, a first rope binding opening and a first inner buckle mechanism are provided;

[0009] The breeding box has an outer buckle mechanism at its bottom end, which is engaged with the first inner buckle mechanism, and the breeding box is detachably connected to the fixed plate through the outer buckle mechanism and the first inner buckle mechanism. A door slot is provided on the front of the breeding box, and a switchable door panel is installed in the door slot. The door panel is provided with an observation port and a feeding port. A ventilation and water inlet and a drainage port are provided on the back of the breeding box. A second inner buckle mechanism is provided on the top of the breeding box, and the second inner buckle mechanism is engaged with the outer buckle mechanism, so as to stack and assemble a predetermined number of breeding boxes according to needs.

[0010] The fixing anchor has a limiting end head at its top, and a fixing anchor is inserted into the fixing anchor placement port of the fixing plate, and installation and disassembly are achieved through the limiting end head and the removal hole.

[0011] In this implementation, the specific process is:

[0012] Preparation stage: According to the depth of the beach mud, choose the appropriate anchor length. Insert the anchor into the anchor placement hole of the fixing plate and fix it through the limit end and the removal hole.

[0013] Installation stage: Place the fixing plate on the beach mud, and ensure that the fixing anchor is inserted into the mud to provide a stable support. The outer buckle mechanism at the bottom of the breeding box and the first inner buckle mechanism of the fixing plate are connected to each other to achieve the connection between the breeding box and the fixing plate.

[0014] Configuration stage: According to the needs, a predetermined number of breeding boxes are stacked and assembled by mutually engaging the second inner buckle mechanism and the outer buckle mechanism. Multiple aquaculture equipment are connected and laid into a desired shape using the first and second rope tying ports and corresponding ropes to form an overall breeding system.

[0015] Management stage: Observe the growth of crabs through the observation port on the door panel. Feed crabs regularly through the feeding port. Drain wastewater from the breeding box through the drain port as needed. Secure the door panel with a locking device (such as a lock or knob) to prevent crabs from escaping.

[0016] Maintenance stage: Regularly check the stability of the breeding boxes and fixing plates to ensure that they are not loose or damaged. Clean up the debris and residues in the breeding boxes to keep the breeding environment clean. Update the breeding information, crab species and breeding date on the sign.

[0017] In some specific embodiments, the first inner buckle mechanism and the second inner buckle mechanism have the same structure;

[0018] The second inner buckle mechanism includes a spiral bevel, a fixed block, an elastic positioning piece and a slot. The fixed block is fixedly connected to the breeding box. The spiral bevel is arranged at the top of the breeding box. One end of the spiral bevel is through-connected with the slot. The interior of the fixed block is fixedly connected to the elastic positioning piece. An outer buckle block is arranged on the outer side of the outer buckle mechanism. The outer buckle block rotates along the spiral bevel to enter the interior of the slot and is positioned and fixed under the action of the elastic positioning piece.

[0019] The first inner buckle mechanism and the second inner buckle mechanism adopt the same structural design, that is, both include a spiral chute, a fixing block, an elastic positioning member and a slot. This design not only simplifies the production process and reduces the manufacturing cost, but also ensures the connection stability and reliability between the breeding box and the fixing plate and between the breeding boxes. At the same time, since the two have the same structure, the breeder does not need to distinguish them during installation and disassembly, and the operation is easier.

[0020] In some specific implementations, a limiting slot is provided on the fixing block, and the elastic positioning member adjusts the position of the limiting plate in the spiral bevel groove through the fixing bolt and the elastic member, thereby achieving engagement and release with the slot.

[0021] In the second inner buckle mechanism, the setting of the spiral chute enables the outer buckle block to rotate along it and enter the slot, so as to achieve the stacking and fixing of the breeding boxes. The elastic positioning member adjusts the position of the limit plate in the spiral chute through the fixing bolt and the elastic member, thereby ensuring the stable positioning of the outer buckle block in the slot. This design not only improves the stability of the stacking, but also allows the breeding boxes to be easily disassembled when necessary, which is convenient for cleaning and maintenance.

[0022] In some specific embodiments, handles are provided on both sides of the breeding box for carrying and grasping the rotating breeding box, so as to realize the disassembly and assembly of multiple breeding boxes;

[0023] The top of the breeding box is provided with a second rope-binding opening.

[0024] The handles on both sides of the breeding box are not only convenient for farmers to carry the breeding box, but also used to grasp and rotate the breeding box to realize the disassembly and assembly of multiple breeding boxes. The second rope binding port allows multiple breeding equipment to be connected and laid into the required shape through ropes to form an integrated breeding system. This design not only improves the flexibility and scalability of the breeding system, but also facilitates unified management and maintenance by farmers.

[0025] In some specific embodiments, the fixed anchors can be set to different lengths to adapt to beach mud of different depths to ensure stable installation of the fixed plates and the breeding boxes.

[0026] The length of the anchor can be set according to the depth of the beach mud to adapt to environments of different depths. This design ensures that the fixing plate and the breeding box can be stably installed on the beach mud of different depths, avoiding breeding risks caused by unstable fixing. At the same time, it also improves the adaptability and flexibility of the breeding system.

[0027] In some specific embodiments, after a plurality of aquaculture equipment are connected and laid into a desired shape through the first rope binding opening, the second rope binding opening and corresponding ropes, an integrated aquaculture system can be formed, which is convenient for management and maintenance.

[0028] By connecting multiple aquaculture equipment through the first rope binding opening, the second rope binding opening and the corresponding ropes, an overall aquaculture system of a desired shape can be laid out. This design not only improves the aquaculture efficiency, but also facilitates the unified management and maintenance of the aquaculture operator. At the same time, the shape and size of the aquaculture system can be adjusted according to actual needs, meeting the requirements of different aquaculture scales and needs.

[0029] In some specific embodiments, the fixing plate is configured as a rectangular parallelepiped structure with a length of 80CM, a width of 70CM, and a height of 10CM, and the fixing anchor placement opening is configured as a cubic groove with a length, width, and height of 10CM;

[0030] The fixed anchor is a rectangular parallelepiped with a length and width of 10CM and a height of 50CM to 100CM. The limiting end is set as a regular quadrangular trapezoidal platform, the length and width of the bottom surface is a square of 10CM, the length and width of the top surface is a rectangle of 15CM, and the height is 5CM.

[0031] In some specific embodiments, the breeding box is set to be a cylinder with a diameter of 42CM and a height of 18CM, the length of the door panel is set to 20CM, the height is set to 13CM, the top of the door panel is 3.5CM away from the top of the breeding box, the number of observation ports is set to six, the number of feeding ports is set to one, the number of ventilation and water ports is set to five, and the shape is set to a circular hole with a diameter of 1CM, and the bottom end of the drainage port is 1CM away from the bottom of the inner side of the breeding box.

[0032] In some specific embodiments, the door panel and the door slot are fixedly connected by a locking device, and the locking device includes but is not limited to a lock and a knob.

[0033] The door panel and the door slot are fixedly connected by a locking device, which includes but is not limited to a lock and a knob. This design not only ensures the stability of the door panel, prevents the crabs from escaping and external interference, but also facilitates the farmers to operate the switch.

[0034] In some specific embodiments, both the breeding box and the fixed plate are provided with identification plates for recording, including but not limited to, breeding information, crab species and breeding date.

[0035] Identification plates are set on the breeding boxes and fixed plates to record key information such as breeding information, crab species and breeding date. This design not only facilitates breeding management and record keeping for breeders, but also helps improve breeding efficiency and accuracy. At the same time, it also provides valuable data support for subsequent breeding analysis and research.

[0036] The beneficial effects of the present invention are:

[0037] 1. The present invention adopts a modular structure, so that the breeding boxes can be flexibly combined according to actual needs, avoiding the waste of resources caused by excessive purchases, and also simplifying the inventory management and maintenance process, further reducing the operating cost. At the same time, the breeding boxes and the fixed plates are quickly connected and disassembled through the inner buckle mechanism and the outer buckle mechanism, so that the whole system can be flexibly configured according to actual needs, which is convenient for the independent operation of a single breeding box and supports the stacking of multiple breeding boxes, greatly improving the utilization rate of the breeding space. The fixed anchors are set to different lengths, which can adapt to various beach mud environments from shallow to deep, ensuring the stable installation of the breeding system and providing a stable growth environment for crabs;

[0038] 2. The observation port on the door panel of the breeding box enables the breeder to directly observe the growth status and health of the crabs, and timely discover and deal with abnormal situations. Through the first rope binding port and the second rope binding port, multiple breeding equipment can be connected into an overall breeding system, which is convenient for unified management and maintenance and reduces the breeding cost. The ventilation and drainage ports on the back of the breeding box ensure the air circulation and water quality in the breeding box, which is conducive to the healthy growth of crabs and reduces the impact on the environment during the breeding process. The various components of the breeding box are reasonably designed and easy to disassemble and clean, which reduces the generation of waste during the breeding process and conforms to the concept of sustainable development.

[0039] 3. The modular breeding system can quickly adjust the breeding scale and flexibly respond to market changes. Whether it is expanding production or adjusting breeding varieties, it can respond quickly and maximize breeding benefits. BRIEF DESCRIPTION OF THE DRAWINGS
