Description

Technical Field

[0001] The utility model relates to the technical field of crayfish breeding, in particular to a crayfish breeding cage structure that is convenient for catching. Background Art

[0002] Cage aquaculture is a high-density intensive aquaculture form, which can generally be carried out in large water bodies such as rivers, reservoirs, lakes, ponds, etc. with good conditions. The water quality in large water bodies is fresh and the dissolved oxygen is sufficient, which is conducive to the growth of crayfish. The cage aquaculture cycle is short, the survival rate of crayfish is high, the yield is high, and the benefits are good. It is a promising aquaculture method.

[0003] However, in the existing cage farming process, the shrimps need to be caught by manually operating the tools, which has a relatively low fishing efficiency and can also cause damage to the shrimp fry during fishing. Utility Model Content

[0004] The purpose of the utility model is to provide a crayfish breeding cage structure that is easy to catch. At the same time, the elastic pull ropes around the lifting screen can be retracted to lift the lifting screen upward from the bottom of the breeding net bag, so that the inside of the breeding net bag can be fished out at once, thereby improving the fishing efficiency and solving the problems in the existing technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a crayfish breeding cage structure that is convenient for fishing, comprising a cage float and a breeding net bag, the breeding net bag being installed below the cage float, the cage float being provided with a hollow structure inside, floating gas cylinders being provided below all four sides of the cage float, the breeding net bag being provided with a lifting screen inside, the breeding net bag cooperating with the cage float to realize unitized breeding operation, a certain number of crayfish being bred in a designated breeding net bag, and the cage float being able to float the top of the breeding net bag on the water surface to prevent the crayfish from escaping.

[0006] Furthermore, a binding ring is provided on the inner side of the cage floating frame, and the binding ring is connected to the cage floating frame through an internal thread. The binding ring can limit the pull rope to avoid misalignment of the lifting screen when the pull rope is retracted and released.

[0007] Furthermore, tensioning wheel frames are provided above all four sides of the net cage floating frame, and the tensioning wheel frames are connected to the net cage floating frame by screws. The tensioning wheel frames can reduce the friction resistance generated by the pull rope when it is retracted and released, thereby improving the net collection efficiency.

[0008] Furthermore, a floating interface is provided between the floating gas cylinder and the net cage floating frame, and the floating gas cylinder is connected to the net cage floating frame through the floating interface. The floating gas cylinder can enhance the buoyancy of the net cage floating frame and prevent the net cage floating frame from sinking.

[0009] Furthermore, net bag buckles are provided on all four sides of the breeding net bag, and the net bag buckles are connected to the net cage floating frame through locks.

[0010] Furthermore, elastic pull ropes are provided around the lifting screen, which are connected to the tensioning wheel frame through the tie ring buckle. At the same time, the elastic pull ropes around the lifting screen can be contracted to lift the lifting screen upward from the bottom of the breeding net bag, so that the inside of the breeding net bag can be scooped out at once, thereby improving the fishing efficiency.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. This utility model can simultaneously retract the elastic ropes around the lifting screen to lift the lifting screen from the bottom of the breeding net bag, so that the inside of the breeding net bag can be fished out at once, thereby improving the fishing efficiency;

[0013] 2. In the present invention, the breeding net bag cooperates with the cage floating frame to realize unitized breeding operation. A certain number of crayfish can be cultured in a designated breeding net bag, and the cage floating frame can float the top of the breeding net bag on the water surface to prevent the crayfish from escaping.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] In order to solve the problem that the existing cage culture process requires manual operation of tools to catch shrimp, which has relatively low efficiency and may cause damage to shrimp fry during fishing; please refer to Figure 1-4 , the utility model provides the following solutions:

[0021] A crayfish breeding cage structure that is easy to catch includes a cage float 1 and a breeding net bag 2. The breeding net bag 2 is installed below the cage float 1. A hollow structure is provided inside the cage float 1. Floating gas cylinders 4 are provided below the four sides of the cage float 1. A lifting screen 3 is provided inside the breeding net bag 2. The breeding net bag 2 cooperates with the cage float 1 to realize unitized breeding operations. A certain number of crayfish are bred in the designated breeding net bag 2. The cage float 1 can float the top of the breeding net bag 2 on the water surface to prevent the crayfish from escaping.

[0022] Specifically, a binding ring buckle 102 is provided on the inner side of the cage floating frame 1, and the binding ring buckle 102 is connected to the cage floating frame 1 through an internal thread. The binding ring buckle 102 can limit the pull rope to avoid misalignment of the lifting screen 3 when the pull rope is retracted and released.

[0023] Specifically, tensioning wheel frames 101 are provided above all four sides of the net cage floating frame 1. The tensioning wheel frames 101 are connected to the net cage floating frame 1 by screws. The tensioning wheel frames 101 can reduce the friction resistance generated by the pull rope when it is retracted and released, thereby improving the net collection efficiency.

[0024] Specifically, a floating port 401 is provided between the floating gas cylinder 4 and the net cage floating frame 1. The floating gas cylinder 4 is connected to the net cage floating frame 1 through the floating port 401. The floating gas cylinder 4 can enhance the buoyancy of the net cage floating frame 1 and prevent the net cage floating frame 2 from sinking.

[0025] Specifically, net bag buckles 201 are provided on all four sides of the breeding net bag 2, and the net bag buckles 201 are connected to the cage floating frame 1 through locks.

[0026] Specifically, elastic pull ropes 301 are provided around the lifting screen 3, and the elastic pull ropes 301 are connected to the tensioning wheel frame 101 through the binding ring buckle 102. At the same time, the elastic pull ropes 301 around the lifting screen 3 can be retracted to lift the lifting screen 3 upward from the bottom of the breeding net bag 2, so that the inside of the breeding net bag 2 can be scooped out at once, thereby improving the fishing efficiency.

[0027] The working principle is to culture a certain number of crayfish in a designated breeding net bag 2, and the cage float 1 can float the top of the breeding net bag 2 on the water surface to prevent the crayfish from escaping. When fishing is needed, the elastic pull rope 301 around the lifting screen 3 is retracted at the same time, and the elastic pull rope 301 is pulled out along the binding ring buckle 102. The binding ring buckle 102 can limit the pull rope to avoid the lifting screen 3 from being misplaced when the pull rope is retracted and released. In this way, the lifting screen 3 can be lifted upward from the bottom of the breeding net bag 2, so that the inside of the breeding net bag 2 can be fished out at once, thereby improving the fishing efficiency.
