Description

Technical Field

[0001] The utility model relates to the technical field of crayfish breeding equipment, in particular to a semi-automatic collection cage. Background Art

[0002] Ground traps are often used in fishing in daily life, especially in small pond lobster fishing. Ground traps are mostly suitable for farms, personal fish ponds, shallow water areas of reservoirs, small streams or lakes and other waters with slow water flow. They are used in farms and fish ponds to improve fishing results, which is convenient and fast.

[0003] At present, fishing ground traps are usually used to catch crayfish, and they are lengthened and enlarged to cope with the lack of manpower in family crayfish farming. However, this method has the following defects:

[0004] 1. The lack of manpower to use lengthened fishing cages for family farming will lengthen the journey of the fishing cages, making it easy for crayfish to die in the fishing cages. This is because fish swim faster than shrimps, and fish can quickly gather at the spiracles at the tail to breathe and wait for harvest. Once crayfish take a detour, they will die of lack of oxygen if they do not breathe for a long time. The bacteria produced by the decay of crayfish after death will also seriously pollute the water quality.

[0005] 2. When lengthening the fishing cage for collection, it is necessary to drive the crayfish from the gate to the tail of the cage, then untie the tail of the cage, pour out the catch, and then tie the tail of the cage tightly, which wastes time and energy and affects the collection time and economic benefits. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a semi-automatic collection cage for solving the problem in the prior art that crayfish are prone to die due to lack of oxygen in the fishing cage and are inconvenient to collect.

[0007] To achieve the above-mentioned purpose and other related purposes, the utility model provides a semi-automatic collection cage, including a cage body for one-way entry of crayfish, a collection frame connected to the cage body for centralized collection of crayfish, a connecting assembly connecting the cage body and the collection frame, and a buoy net cover movably connected to the upper side of the collection frame so that the air permeable end extends to the water surface for ventilation of the crayfish.

[0008] By adopting the above technical scheme, the crayfish can be allowed to enter the cage net in one direction through the cage body to achieve the initial capture of the crayfish, and then the connecting component allows the crayfish in the cage body to crawl into the collecting frame, and the collecting frame will collect the crayfish in a unified manner. At the same time, a buoy net cover is arranged on the upper side of the collecting frame, and the buoy drives one end of the buoy net cover to float to the water surface to form a ventilation port, which can enable the crayfish in the collecting frame to swim to the ventilation port for breathing, thereby preventing the crayfish from suffocating in the collecting frame and reducing the death of the crayfish. In addition, when collecting, the crayfish can be quickly collected by only opening the buoy net cover on the collecting frame, and the operation is simple and convenient.

[0009] In one embodiment of the utility model, the cage body includes a frame, a cage net arranged on the frame, eight-shaped doors arranged at both ends of the frame, and a shrimp inlet and outlet arranged on the side wall of the frame for one-way entry of crayfish.

[0013] In one embodiment of the utility model, the cross-sectional shape of the collection frame is set to an inverted trapezoidal structure that is small at the bottom and large at the top. The side wall of the collection frame has a through hole connected to the connecting barrel, and the upper side of the collection frame is also provided with a groove connected to the buoy net cover.

[0014] By adopting the above technical solution, the buoy net cover can be installed corresponding to the groove and designed as an inverted trapezoidal structure, which can make the upper opening of the collection frame larger, making it easier to collect and pour out crayfish and also easier for crayfish to move in the collection frame.

[0015] In one embodiment of the utility model, the buoy net cover is connected to the upper side of the collection frame through an elastic rope, and the buoy net cover has a net bag extending upward, and the net bag is provided with a buoy that can be subjected to force to drive the net bag to float upward.

[0016] By adopting the above technical solution, the net bag can be driven to float to the water surface under the action of buoyancy by the buoy. The structure is simple and convenient, no manual operation is required, and the survival rate of crayfish can be greatly improved.

[0017] In one embodiment of the utility model, the connecting barrel is configured as a conical structure, the larger opening end of the connecting barrel is connected to the cage net, and the other end is clamped with the fixing frame. The outer edge of the larger opening end of the connecting barrel is also provided with a connecting groove for facilitating connection with the cage net.

[0018] By adopting the above technical solution and the conical design, it is easier for crayfish to enter the collection frame through the connecting barrel, and by providing a connecting groove outside the connecting barrel, it is easier to connect the cage body to the connecting barrel and it is not easy to detach.

[0019] In one embodiment of the utility model, the fixing frame is adapted to the shape of the collection frame, the side wall of the fixing frame is provided with a positioning hole connected to the connecting barrel, the side wall of the fixing frame has a sliding groove engaged with the connecting barrel, and the inner wall of the fixing frame is also provided with a positioning groove engaged with the collection frame so that the through hole is aligned with the positioning hole.

[0020] By adopting the above technical solution, the shape of the fixing frame is adapted to that of the collecting frame, which makes it easier to install the collecting frame in the fixing frame. By providing a positioning groove, the collecting frame can be plugged into the positioning groove during installation, so that the through hole on the collecting frame corresponds to the positioning hole on the fixing frame, thereby ensuring that the connecting bucket can be connected to the inside of the collecting frame, allowing the crayfish to directly enter the collecting frame.

[0021] In one embodiment of the utility model, the buoy net cover is also provided with a snap button that can flip the buoy net cover body to facilitate the pouring out of the crayfish.

[0022] By adopting the above technical solution and the snap-lock design, the buoy net cover can be partially flipped by opening the snap-lock, so that the crayfish in the collection frame can be poured out from the opening formed by the flipping. The operation is simple and convenient, and the collection of crayfish can be made more convenient.

[0023] In one embodiment of the utility model, a second whisker net extending inwardly is further provided at the through hole to allow the crayfish to enter in one direction.

[0024] By adopting the above technical solution and setting up a second whisker net, it is possible to further prevent crayfish from leaving the collection frame and entering the connecting bucket.

[0025] In one embodiment of the utility model, the cage body also includes a shrinkage frame arranged at the end of the frame body, which can gather the ends of the cage net to reduce the outlet area of ​​the cage net, and the shrinkage frame is located outside the eight-shaped door.

[0026] By adopting the above technical solution, the cage net can be gathered by the contraction frame, thereby reducing the area of ​​the cage net outlet end, making it easier to connect the cage net with the connecting assembly.
