Description

Technical Field

[0001] The utility model belongs to the technical field of crab fishing devices, and particularly relates to a novel crab fishing device for a crab-raising container. Background Technique

[0002] The principle of the crab-raising container is mainly based on the container-type three-dimensional circulating water aquaculture system. By controlling the concentration of inorganic salt ions and optimizing the sewage discharge structure of the aquaculture unit, the whole process of the aquaculture environment can be controlled and the flexibility of the aquaculture device can be realized. The containers can be assembled three-dimensionally, saving space, and can avoid the interference of external factors such as weather, temperature, water quality, etc., realizing off-season cultivation and year-round aquaculture. Each crab lives in a separate "crab apartment". This not only improves the survival rate of crabs, but also avoids fighting when crabs are together because crabs are highly aggressive. The design of this device aims to provide a stable and controllable aquaculture environment to improve the efficiency of aquaculture and the survival rate of crabs.

[0003] Most of the existing crab fishing devices are manually used with fishing nets to catch crabs, which not only increases the labor intensity of workers, increases the labor cost, but also reduces the work efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-3 , the present invention provides a technical solution: a new type of crab-catching device for a crab-raising container, which includes a first crab-catching bucket 1 and a second crab-catching bucket 2. On one side above the first crab-catching bucket 1, there is a connecting block 3. Inside the connecting block 3, there is a first connecting piece 4. One end of the first connecting piece 4 is provided with a support rod 5. One end of the support rod 5 is provided with a second connecting piece 6. On one side of the second connecting piece 6, there is a mounting block 7. On the top of the mounting block 7, there is a traction block 8. On the surface of the traction block 8, there is a connecting hole 9. At the bottom of the mounting block 7, there is a hydraulic rod 10. Inside the first crab-catching bucket 1, there are connecting shafts 11. Between the connecting shafts 11, there is a connecting plate 12. On the top of the connecting plate 12, there is a bottom plate 13. On one side of the first crab-catching bucket 1, there is a fixed net 14. At the bottom of the first crab-catching bucket 1, there is a drainage hole 15.

[0019] Specifically, the structures between the first crab-catching bucket 1 and the second crab-catching bucket 2 are the same. On one side above the first crab-catching bucket 1 and the second crab-catching bucket 2 respectively, there are connecting blocks 3. Inside the connecting blocks 3, the first connecting pieces 4 are rotatably connected. One end of the first connecting piece 4 is fixedly connected to the support rod 5. One end of the support rod 5 is fixedly installed with the second connecting piece 6. The second connecting piece 6 is arranged at the four corners below the mounting block 7 and is rotatably connected. In the middle of the top end of the mounting block 7, the traction block 8 is fixedly installed. On the surface of the traction block 8, the connecting hole 9 is fixedly opened. At the bottom of the mounting block 7, the hydraulic rod 10 is fixedly installed. Inside the first crab-catching bucket 1 and the second crab-catching bucket 2 respectively, the connecting shafts 11 are rotatably connected. Between the connecting shafts 11 inside the first crab-catching bucket 1 and the second crab-catching bucket 2, the connecting plate 12 is fixedly connected. One side of the connecting plate 12 and the inner sides of the first crab-catching bucket 1 and the second crab-catching bucket 2 are respectively rotatably connected. On the top of the connecting plate 12, the bottom plate 13 is fixedly connected. The bottom output end of the hydraulic rod 10 is fixedly connected to the top of the bottom plate 13.

[0020] In this embodiment, through the traction block 8 and the connection hole 9 provided, it is convenient to connect the device to the external driving arm. The hydraulic rod 10 is electrically connected to an external power source and is controlled by a power switch. When the hydraulic rod 10 is started, the operation of the hydraulic rod 10 can drive the bottom output end to extend, so that the output end of the hydraulic rod 10 exerts a downward force on the bottom plate 13. After the downward pressure is transmitted to the lower part through the bottom plate 13, it can drive the parts of the first ladle 1, the second ladle 2 connected to the connecting shaft 11 to move downward and turn over. By setting the support rod 5, it can play a role in pulling the left and right sides of the first ladle 1 and the second ladle 2. The first ladle 1 and the second ladle 2 respectively turn downward around the connecting shaft 11, so that the bottoms of the first ladle 1 and the second ladle 2 are in an open state. When the hydraulic rod 10 retracts, it can drive the first ladle 1 and the second ladle 2 to reset, so that the crabs in the water can be locked inside the first ladle 1 and the second ladle 2, achieving the effect of catching crabs. Through the drainage holes 15 and the fixed net 14 provided, it is convenient to drain the excess water in the first ladle 1 and the second ladle 2.
