Description
Technical Field
[0001] The utility model belongs to the technical field of crab cages, and particularly relates to a releasing device for crab cages. Background Art
[0002] In the early days, the release and recovery of crab cages mainly relied on manual operation. Fishermen needed to personally put the crab cages into the sea and manually recover the crab cages after a period of time. The capacity and quantity of crab cages were limited by manpower, resulting in relatively low fishing efficiency. With the development of technology, some semi-mechanized crab cage releasing devices began to appear, such as using small robotic arms or pulley systems to assist in the launching and recovery of crab cages. This kind of device improved work efficiency, but still required a lot of human participation.
[0003] The operation of crab cage fishing boats has basically been mechanized, but in the processes of releasing and recovering the cages, manual assistance is still required. During the operation of crab cages, some fish will accidentally enter the crab cages, which will reduce the catch of crabs by the crew and cause economic losses. If the crab cages are lifted and released manually, the labor cost will be greatly increased and the fishing efficiency will be greatly reduced. Content of the Utility Model
[0004] The purpose of the utility model is to provide a releasing device for crab cages. Through the function of the guiding tube, the device is provided with a guiding tube on the cage cover, which can facilitate the escape of fry accidentally entering the crab cage body. At the same time, the distance between the two partitions can be adjusted, so that the staff can adjust the inner wall gap of the guiding tube according to the size of the crabs, avoiding the situation that small crabs escape from the guiding tube, making the application range of the device wider, and solving the problems that in the existing operation process of crab cages, some fish will accidentally enter the crab cages, which will reduce the catch of crabs by the crew and cause economic losses. If the crab cages are lifted and released manually, the labor cost will be greatly increased and the fishing efficiency will be greatly reduced.

Specific Embodiment 1
[0043] Please refer to Figures 1-7 , the present utility model is a release device for a crab cage, including a crab cage body 1, and a cage cover 2 is fixed on the top of the crab cage body 1; an adjusting device 3 is fixed on the upper surface of the cage cover 2, and an outlet 4 is opened on the surface of the cage cover 2; the adjusting device 3 includes an adjusting shell 5, and the adjusting shell 5 is fixedly connected with the cage cover 2; a hydraulic cylinder 6 is fixed on the top of the adjusting shell 5, the output shaft of the hydraulic cylinder 6 penetrates through the adjusting shell 5, and an adjusting block 7 is fixed on the output shaft of the hydraulic cylinder 6; adjusting grooves 8 are opened on both sides of the adjusting shell 5, and a sliding groove 9 is opened on the side of the adjusting shell 5 away from the hydraulic cylinder 6; a moving plate 10 is slidably connected inside the adjusting groove 8, and a partition plate 11 is fixed at the bottom of the moving plate 10; one end of the outlet 4 is fixedly connected with a guiding pipe 12, limiting grooves 13 are opened on both sides of the guiding pipe 12, and a protection port 14 is fixed at one end of the guiding pipe 12.
[0044] Specifically, the protection port 14 is of a flared structure, and the partition plate 11 is tangent to the inner wall of the limiting groove 13; moving blocks 15 are fixed on both sides of the adjusting block 7, and the moving plate 10 is of a right trapezoidal structure; a moving groove 16 is opened on the inclined surface of the moving plate 10.
[0045] Furthermore, the moving block 15 is of a "T" type structure, and the moving block 15 is matched with the inner wall of the moving groove 16; the moving block 15 is slidably connected with the moving groove 16; limiting strips 17 are fixed on both sides of the moving plate 10, and connecting grooves 18 are opened on both sides of the inner wall of the adjusting groove 8; the limiting strips 17 are slidably connected with the connecting grooves 18.
[0046] The operation process of this embodiment is as follows: When this device is in use, put the crabs into the crab cage body 1, and open the hydraulic cylinder 6. According to the volume of the crabs in the crab cage body 1, adjust the position of the partition plate 11 in the limit groove 13. That is, when the volume of the crabs in the crab cage body 1 is small, the output shaft of the hydraulic cylinder 6 can be moved away from the partition plate 11. At this time, the adjusting block 7 at one end of the output shaft of the hydraulic cylinder 6 moves upward accordingly. When the adjusting block 7 moves upward, the moving blocks 15 on both sides thereof move upward accordingly, and at the same time, it slides inside the moving groove 16, so that the moving plates 10 on both sides move towards the middle and close. When the moving plate 10 moves towards the center of the adjusting shell 5, the partition plate 11 at the bottom of the moving plate 10 also moves towards the inside of the adjusting shell 5.

The device is provided with a guide pipe 12 on the cage cover 2, which can facilitate the escape of the fry that accidentally enter the crab cage body 1. At the same time, the distance between the two partition plates 11 can be adjusted, which is convenient for the staff to adjust the inner wall gap of the guide pipe 12 according to the size of the crabs, avoiding the situation that small-volume crabs escape from the guide pipe 12, and making the applicable range of the device wider. Specific Embodiment Two
