Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to a shrimp catching cage. Background Art

[0002] Crayfish farming mainly includes rice-shrimp farming, pond farming, large water surface farming, etc. At present, when catching crayfish, they are usually caught manually using shrimp cages, including two devices: retractable and foldable ground cages and fixed-size cylindrical shrimp cages.

[0003] The existing foldable shrimp cage is composed of a frame and a fence, and the fence is made of plastic nylon. After long-term use, the frame is prone to deformation and the fence is damaged, and it is not easy to repair, and the cost of use is high. The ground cage is not easy to fix during use, and its position is easy to move with the water flow, affecting the fishing effect. At the same time, the ground cage is too long when in use and needs to be completely put into water before use. This makes the use and collection process of the ground cage cumbersome, time-consuming and labor-intensive, and not suitable for mechanized fishing.

[0004] The existing cylindrical shrimp cage is made of a frame and a mesh. It cannot be fixed in position during use and is easily affected by water flow. In addition, its cylindrical shape makes it difficult for crayfish to enter, and the single catch is small. When crayfish enter the shrimp storage area, the internal space is also small, and squeezing is easy to occur, causing casualties of crayfish and affecting economic benefits. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] In this embodiment, if Figure 1As shown, a shrimp cage includes a cage body 2, a plurality of shrimp inlets 3 are opened at the lower part of the cage body 2, a plurality of inverted whiskers 7 are arranged on the inner end of the shrimp inlet 3, a round hole is opened at the top of the cage body 2, a shrimp outlet tube 1 is arranged in the round hole, a fixing mechanism 8 is arranged at the bottom of the cage body 2, the fixing mechanism 8 is used to fix the cage body 2 in the water, and a bait box 6 is arranged at the upper end of the fixing mechanism 8, the bait box 6 is located in the cage body 2, preferably, a plurality of through holes b9 are opened on the surface of the bait box 6, specifically, by opening the through holes b9 on the surface of the bait box 6, it is convenient for the bait in the bait box 6 to emit odor, thereby better attracting crayfish to enter the cage body 2. By setting the bait box 6 on the fixing mechanism 8 and inserting the fixing mechanism 8 into the mud, the position of the shrimp cage is fixed to prevent it from floating, and at the same time, the bait box 6 is prevented from being dragged out of the cage body 2 by the crayfish or floating on the water surface, so that the trapping effect lasts for a long time. At the same time, a plurality of shrimp inlets 3 are opened at the lower part of the cage body 2 to trap crayfish in different directions, and a plurality of inverted whiskers 7 are provided on the inner end of the shrimp inlet 3 to prevent it from crawling out of the cage body 2, thereby ensuring the catch.

[0029] Further, such as Figure 2 As shown, the fixing mechanism 8 includes a bottom plate 4 and a fixing rod 5. A mounting hole is provided in the middle of the bottom plate 4, and the fixing rod 5 is installed in the mounting hole. Preferably, a spike 10 is provided at the lower end of the fixing rod 5, and a limit cap 11 is provided at the upper end of the fixing rod 5. A hanging ring 12 is provided on the upper surface of the limit cap 11. A hook 13 corresponding to the hanging ring 12 is provided at the lower end of the bait box 6. A plurality of fixing bolts 15 are also provided on the bottom plate 4. The fixing bolts 15 are used to fix the bottom plate 4 to the bottom of the cage body 2. Preferably, the fixing bolts 15 are distributed in a triangular shape on the bottom plate 4. Further, as Figure 3As shown, a plurality of drainage holes are provided at the bottom of the cage body 2, and through holes 14 corresponding to the drainage holes are provided on the bottom plate 4. The through holes 14 are distributed in a circle on the bottom plate 4, and the through holes 14 are located on the inner side of the fixing bolts 15. Specifically, when the shrimp cage needs to be used, the staff first fixes the bottom plate 4 to the bottom of the cage body 2 by means of the fixing bolts 15. Since the fixing bolts 15 are distributed in a triangle shape on the bottom plate 4, the stability of the fixing of the bottom plate 4 can be ensured. When the bottom plate is fixed, the staff then passes the fixing rod 5 through the shrimp outlet tube 1 from top to bottom through the cage body 2 and inserts it into the installation hole, thereby inserting it into the mud. The main function of the spike 10 at the lower end of the fixing rod 5 is to facilitate the insertion of the fixing rod 5 into the mud, thereby fixing the position of the shrimp cage and preventing it from floating in the water. Finally, the hook 13 at the lower end of the bait box 6 is hung in the hanging ring 12. The bait box 6 is located in the cage body 2. Since the fixing rod 5 is inserted into the mud, the bait box 6 can be prevented from being dragged out of the cage body 2 or floating on the water surface by the crayfish, so that the trapping effect lasts for a long time. When it is necessary to collect the shrimp trap, the staff pulls the fixing rod 5 out of the mud by holding the shrimp outlet tube 1 and drags it out of the water surface. At this time, the water in the cage body 2 flows out through the shrimp inlet 3 and the through hole 14. Since the inner end of the shrimp inlet 3 is provided with a barb 7, the crayfish in the cage body 2 can be effectively prevented from running out of the cage body 2 with the water flow. When the water in the cage body 2 is drained, the staff inverts the cage body 2 to pour the crayfish in the cage body 2 out of the shrimp outlet tube 1. In this embodiment, when trapping crayfish, the upper end of the shrimp outlet tube 1 is blocked by a baffle (not shown in the figure). In order to prevent the baffle from falling, a heavy object such as a stone can be placed above the baffle.

[0030] In this embodiment, the lower surface diameter of the limiting cap 11 is larger than the diameter of the mounting hole. Specifically, the main function of the lower surface diameter of the limiting cap 11 being larger than the diameter of the mounting hole is to prevent the fixing rod 5 from separating from the bottom plate 4 during use, resulting in failure to effectively fix the cage body 2.

[0031] Furthermore, the shrimp inlet 3 is inclined downward, and the inlet diameter of the shrimp inlet 3 is larger than the outlet diameter of the shrimp inlet 3, and the diameter of the plane where the end of the inverted whisker 7 connected to the shrimp inlet 3 is located is larger than the diameter of the plane where the other end of the inverted whisker 7 is located. In other words, the shrimp inlet 3 is a conical opening, and the inlet diameter of the shrimp inlet 3 is larger than the outlet diameter of the shrimp inlet 3, that is, the inner diameter is smaller than the outer diameter, and the inverted whisker 7 is arranged on the inner side of each conical shrimp inlet 3, and the inverted whisker 7 converges toward the center of the circle, and the diameter formed by them does not exceed 3cm. In this embodiment, there are three shrimp inlets 3, and they are evenly distributed at the lower end of the cage body 2, so that crayfish can be trapped from different directions.

[0032] Furthermore, the cage body 2 is integrally formed and is a regular tetrahedron. Specifically, the regular tetrahedron shape of the cage body 2 increases the lower space of the cage body 2, and when the crayfish enters the cage body 2, it is not easy to be squeezed, thereby improving the survival quality and economic benefits of the crayfish.

[0033] In this embodiment, if Figure 4 As shown, the inner wall of the shrimp outlet tube 1 is provided with a handshake plate 16. Specifically, the main function of the handshake plate 16 is to facilitate the staff to hold the shrimp outlet tube 1 when collecting the shrimp cage.

[0034] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
