Embodiment 1

[0049] see figure 1 and figure 2 As shown, the present embodiment provides a crab cage hook, including: a cage hook assembly and a supporting horizontal plate.

[0050] The cage hook assembly comprises a connected middle ring 11 and a bottom ring 12, a movable rod 13 connected with the middle ring 11, and a hook rod 19 connected with the bottom ring 12; Shackle 9; the end of the movable rod 13 away from the intermediate ring 11 is adapted to be inserted into the shackle 9 to form a closed annular cage hook. It should be noted here that the length of the end of the movable rod 13 inserted in the shackle 9 from the shackle 9 should not be too long, too long will cause difficulty in decoupling, and it should not be too short, too short will easily cause crabs. The cage hook 23 falls off during the recovery process.

[0051] As for the support horizontal plate, the movable rod 13 is adapted to pass through the support horizontal plate, and the part of the movable rod 13 insert...

Embodiment 2

[0059] see Figure 4 to Figure 6 As shown, on the basis of the crab cage hook 23 of embodiment 1, the present embodiment provides an automatic decoupling recovery device, including: a support frame 1 and a flap mechanism located in the support frame 1, a crab cage traction mechanism and Crab pot decoupling mechanism.

[0060] Crab cage traction mechanism comprises main traction rope 5 and is located at several traction rings 24 of interval distribution on main traction rope 5; . The flip mechanism includes a recovery plate 6 that is hingedly connected with the support frame 1 and is suitable for swinging around the frame. Several traction rings 24 are used to respectively tow several crab cage hooks 23, that is, several crab cages 3, so that the process of pulling the main traction rope 5 can remove a certain number of crab cages 3 corresponding to the number of traction rings 24. Requirements.

[0061] The crab cage hook 23 of this embodiment is assembled with the tractio...

Abstract

The invention relates to a crab pot hook and an automatic unhooking and recovery device. The hook comprises a crab hook assembly and a support transverse board. The crab hook assembly comprises a middle ring and a bottom ring, a movable rod connected with the middle ring and a hook rod connected with the bottom ring. The middle ring and the bottom ring are connected. The end part, away from the bottom ring, of the hook rod is equipped with a hook ring in a winding manner. The end part, away from the middle ring, of the movable rod is inserted into the hook ring. The movable rod penetrates through the support transverse board. Additionally, the movable rod is inserted into the part of the support transverse board and fixedly connected with the support transverse board.

Description

technical field [0001] The invention relates to the technical field of fishery, in particular to a crab cage hook and an automatic decoupling recovery device. Background technique [0002] When using crab cage trapping to catch crabs in the sea, after the main rope with multiple crab cages is pulled out from the sea by the winch, the crab cages need to be removed manually, and then passed one by one for subsequent crab extraction and sorting Process actions such as crab cages. Generally, a crab cage ship needs to recover 3000-4000 crab cages in one operation, and only about 22 crab cages can be recovered per minute. Therefore, collecting crab cages is a labor-intensive and time-consuming type of work, so the labor cost is high. Moreover, the high-intensity work is easy to make people tired, and the personnel are relatively close to the ship's side during work, so accidents of falling into the sea are easy to occur. In order to reduce costs and improve the safety of fishery...
