Description

Technical Field

[0001] The present application relates to the field of fishing tools, and in particular to a fishing tool for crayfish fry. Background Art

[0002] Crayfish larvae are crayfish that have reached a certain stage of growth after hatching. Crayfish (also known as Procambarus clarkii) are a popular aquatic product. Catching crayfish larvae requires the right tools to ensure efficient harvesting and the health of the larvae. Shrimp cages are typically made of mesh with an internal lure that can be placed in the water to attract the crayfish.

[0003] When using a shrimp cage to trap crayfish, the shrimp cage is generally placed in the water with bait. When the crayfish gather at the bait, the shrimp cage is lifted up from the water. However, the shrimp cage will be affected by the resistance in the water when it is lifted, and the lifting speed is limited, which may cause some crayfish to react and escape from the shrimp cage. In addition, lifting the shrimp cage will cause more violent fluctuations in the water, which will scare the crayfish within a certain range in the water and affect the overall efficiency of catching crayfish.

[0004] In view of the above-mentioned related technologies, the inventor believes that the existing shrimp cage has the defect of suddenly lifting the shrimp cage when catching crayfish, which affects the efficiency of crayfish fishing. Therefore, a crayfish seedling fishing tool is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-3The present invention further describes a tool for catching crayfish seedlings in detail.

[0019] The present application embodiment discloses a tool for catching crayfish seedlings. Figure 1-3 A tool for catching crayfish seedlings includes a shrimp cage 1, a plurality of sinkers 2 are fixedly installed on the bottom edge of the shrimp cage 1, a connecting frame 3 is welded on the upper surface of the shrimp cage 1, a hook 4 is fixedly connected to the middle position of the connecting frame 3 extending to the inside of the shrimp cage 1, a No. 1 pull rope 5 is installed in the middle position of the upper surface of the connecting frame 3, a connecting pull rod 6 is fixed to the top of the No. 1 pull rope 5, a connecting shaft seat 7 is provided on the top of the connecting pull rod 6, a supporting handle 8 is rotatably installed on the outer surface of the connecting shaft seat 7, and a plurality of movable support rods 9 are rotatably installed on the top of the outer surface of the shrimp cage 1. A fishing net 10 is fixedly installed between the two movable support rods 9 and on the outer surface of the shrimp cage 1. A guide slot 11 is provided inside the connecting rod 6, and a connecting piece 12 is movably installed inside the guide slot 11. The outer surface of the connecting piece 12 extends through the guide slot 11 to the outside of the connecting rod 6. The guide slot 11 and the connecting piece 12 are embedded in each other. A No. 2 pull rope 13 is tied between the top of the movable support rod 9 and the outer surface of the connecting piece 12. An adjustment mechanism is also provided on the outer surface of the support handle 8 for controlling the synchronous movement of multiple movable support rods 9.

[0020] By hanging the bait on the hook 4, holding the supporting handle 8 and putting the shrimp cage 1 into the water to lure crayfish, the movable support rod 9 makes the fishing net 10 movable and unfolded under the action of gravity, and makes the limiting block 17 abut against the outer surface of the fixed baffle 16, so that the bait attracts the crayfish into the shrimp cage 1 to feed. When the crayfish gather around the bait in the shrimp cage 1, the fishing net 10 is movable and retracted and closed, so that the retracted fishing net 10 blocks the crayfish, and the shrimp cage 1 is lifted up and out of the water, so that the crayfish are caught in the shrimp cage 1, which reflects the overall catching effect of the shrimp cage 1 on crayfish.

[0021] Reference Figure 1 and Figure 2 The adjustment mechanism includes a through hole 14, which is opened in the middle of the top inner wall of the guide slide 11. The middle of the top of the connecting piece 12 passes through the through hole 14 and is placed on the outer surface of the support handle 8. A No. 3 pull rope 15 is connected. A limit block 17 is fixedly installed on the edge of one end of the No. 3 pull rope 15. A fixed baffle 16 is welded in the middle of one side of the outer surface of the support handle 8. A round hole is opened at the bottom of one side of the fixed baffle 16. One side of the outer surface of the No. 3 pull rope 15 is located inside the round hole, and the outer surface of the limit block 17 is attached to the edge of one side of the fixed baffle 16.

[0022] By slowly pulling the limit block 17, the No. 3 pull rope 15 is driven to move, so that the No. 3 pull rope 15 drives the connecting piece 12 to move along the guide slide 11, and at the same time, the movable connecting piece 12 simultaneously pulls multiple No. 2 pull ropes 13 to move, so that the movable support rod 9 rotates synchronously with the movement of the No. 2 pull rope 13, and then the movable support rod 9 drives the fishing net 10 to retract and close upward, reflecting the activity adjustment effect of the No. 3 pull rope 15 on the fishing net 10.

[0023] The implementation principle of the crayfish seedling fishing tool of the embodiment of the present application is as follows: by hanging the bait on the hook 4, holding the support handle 8 and putting the shrimp cage 1 into the water to lure the crayfish, the movable support rod 9 and the fishing net 10 are naturally drooped under the action of gravity, the fishing net 10 is movably unfolded, and the limiting block 17 is abutted against the outer surface of the fixed baffle 16, the length of the No. 3 pull rope 15 is adjusted to keep the movable support rod 9 in a horizontal state, so that the bait attracts the crayfish to enter the shrimp cage 1 to feed, and when the crayfish gather around the bait in the shrimp cage 1, the limiting block 17 is slowly pulled to drive the No. 3 pull rope 15 to move, so that the No. 3 pull rope 15 drives the connecting piece 12 along the guide slide The groove 11 moves, and at the same time, the movable connecting piece 12 pulls the multiple No. 2 pull ropes 13 to move, so that the movable support rod 9 rotates synchronously with the movement of the No. 2 pull ropes 13, and then the movable support rod 9 drives the fishing net 10 to retract and close upward, so that the retracted fishing net 10 blocks the crayfish and lifts the shrimp cage 1 upward out of the water, so that the crayfish are caught in the shrimp cage 1; compared with the existing technology, this solution has the effect of facilitating the capture of crayfish and gathering them in the shrimp cage 1, thereby improving the overall capture efficiency of crayfish, solving the problem of low efficiency of the shrimp cage 1 in catching crayfish, and avoiding the problem of the shrimp cage 1 being suddenly pulled up and startling the crayfish to flee in all directions.
