Technical Field

[0001] This utility model belongs to the field of crayfish farming technology, specifically, it relates to a crayfish farming cage. Background Technology

[0002] Crayfish farming cages are devices used for crayfish farming. Their main function is to provide a relatively concentrated habitat and growth space for crayfish in the water. Farming cages facilitate crayfish feeding management and harvesting for farmers, and also help control the crayfish's activity range to a certain extent, reducing the possibility of them escaping.

[0003] Crayfish farming plays a vital role in my country's aquaculture industry. However, traditional crayfish farming cages have several shortcomings. For example, existing cages may have flawed structural designs, leading to crayfish swarming and crowding inside, affecting their growth space and health. Furthermore, some existing cages are difficult to clean and maintain after long-term use, and when parts of the cage are damaged, the entire farming system needs to be dismantled, repaired, or replaced, reducing farming efficiency and increasing maintenance costs. Harvesting is also difficult, requiring dismantling the equipment, and subsequent reinstallation is cumbersome if continued farming is desired. Utility Model Content

[0004] To address the aforementioned issues of crayfish easily piling up and crowding inside the cages, affecting their growth space and health, the difficulty in cleaning and maintaining the cages after long-term use, the need to dismantle, repair, or replace the entire farming equipment when a cage is partially damaged, reducing farming efficiency, increasing maintenance costs, and the technical difficulties during harvesting, the basic concept of this utility model is as follows:

[0005] A crayfish farming cage includes a perforated plate, support columns, and a harvesting cage. The adjacent sides of the support column are fixedly connected to the sides of the perforated plate, and a fixing plate is fixedly connected to the outer side of the support column. An airbag float is fixedly installed between two adjacent fixing plates. A combination slot and a combination strip are fixedly connected to the support columns at both ends of the airbag float, respectively. The internal groove of the combination slot corresponds to the shape of the combination strip and is slidably inserted into it. A bottom plate is fixedly connected to the inner side of the lower end of the perforated plate, and several through holes are opened on the bottom plate.

[0006] In a preferred embodiment of the present invention, the coarse-hole plate has several coarse holes on its body, and the left and right ends of the outer side of the coarse-hole plate are fixedly connected to mounting grooves, and a detachable fine-hole plate is snapped into the inside of the mounting grooves.

[0007] In a preferred embodiment of this utility model, the detachable fine-hole plate has a plurality of fine holes on its body, the diameter of the fine holes being smaller than the diameter of the coarse holes, and a limit strip is fixedly connected to the upper end of the detachable fine-hole plate.

[0008] In a preferred embodiment of this utility model, the outer dimensions of the harvesting cage correspond to the inner dimensions of the square cage formed by the perforated plate and are movably connected to it. Furthermore, several transverse meshes are fixedly connected to both sides of the inside of the harvesting cage, and the spacing between the upper and lower parts of the transverse meshes is equal.

[0009] In a preferred embodiment of this utility model, a top plate is fixedly connected to both sides of the upper end of the harvesting cage, and several longitudinal plates are evenly fixedly connected to the lower end of the top plate. The longitudinal plates divide the transverse mesh into square spaces, and a handle is fixedly installed at the upper end of the top plate.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] This invention solves the problem of crayfish easily piling up and crowding inside the cage, affecting their growth space and health, by designing a space-divided design inside the breeding cage. It also allows for the rational and full utilization of the internal space of the breeding cage. At the same time, through the modular design, the breeding cage is divided into several combinable modules. This design facilitates individual cleaning, maintenance and replacement in the later stages, reducing maintenance and replacement costs. Furthermore, the detachable double-layer design facilitates the one-time harvesting of crayfish, increasing harvesting efficiency. And through the use of a detachable fine-perforated plate design, the hole diameter can be adjusted according to the size of the crayfish, adapting to the breeding of crayfish of different ages.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0020] like Figures 1 to 4 As shown, a crayfish farming cage includes a perforated plate 1, support columns 13, and a harvesting cage 6. The adjacent sides of the support column 13 are fixedly connected to the sides of the perforated plate 1, and a fixing plate is fixedly connected to the outer side of the support column 13. An airbag float 5 is fixedly installed between two adjacent fixing plates. A combination slot 3 and a combination strip 4 are fixedly connected to the support column 13 at both ends of the airbag float 5, respectively. The internal groove of the combination slot 3 corresponds to the shape of the combination strip 4 and is slidably inserted into it. A bottom plate 14 is fixedly connected to the inner side of the lower end of the perforated plate 1. Several through holes are opened on the plate body of the bottom plate 14. Several coarse holes are opened on the plate body of the perforated plate 1, and an installation groove 12 is fixedly connected to the left and right ends of the outer side of the perforated plate 1. A detachable fine perforated plate 2 is snapped into the inside of the installation groove 12.

[0021] In this setup, the breeding cages are divided into several modular breeding cage modules that can be combined. If any module is damaged, it can be removed, repaired, or replaced individually. This design facilitates individual cleaning, maintenance, and replacement in the future, reducing maintenance and replacement costs.

[0022] like Figures 1 to 4 As shown, in a specific embodiment, the detachable fine-hole plate 2 has a plurality of fine holes on its plate body. The diameter of the fine holes is smaller than that of the coarse holes, and the upper end of the detachable fine-hole plate 2 is fixedly connected to a limit strip 11.

[0023] In this setup, the detachable perforated plate 2 is designed so that the hole diameter can be adjusted according to the size of the lobster. When raising lobster larvae, the detachable perforated plate 2 can be installed to prevent the lobster larvae from escaping through the holes. This design is suitable for raising lobsters of different ages.

[0024] like Figures 1 to 4 As shown, in a specific embodiment, the outer dimensions of the harvesting cage 6 correspond to the inner dimensions of the square cage formed by the perforated plate 1, and are movably connected to it. Furthermore, several horizontal partitions 7 are fixedly connected to both sides of the inside of the harvesting cage 6, and the spacing between the upper and lower parts of the horizontal partitions 7 is equal.

[0025] In this design, the internal space of the breeding cage is evenly divided into several small square spaces. Since crayfish are burrowing aquatic creatures and prefer relatively small spaces, this design also solves the problem that crayfish tend to pile up and crowd inside the cage, affecting their growth space and health. Furthermore, it allows for the rational and full utilization of the internal space of the breeding cage.

[0026] like Figures 1 to 4 As shown, in a specific embodiment, a top plate 10 is fixedly connected to both sides of the upper end of the harvesting cage 6, and several longitudinal plates 8 are evenly fixedly connected to the lower end of the top plate 10. The longitudinal plates 8 divide the transverse mesh 7 into square spaces, and a handle 9 is fixedly installed at the upper end of the top plate 10.

[0027] Furthermore, the detachable double-layer design allows for easy harvesting of lobsters in one go when they reach harvest season, simply by lifting the harvesting cage 6, thus increasing harvesting efficiency.

[0028] The implementation principle of a crayfish farming cage in this embodiment is as follows:

[0029] This invention divides the internal space of the breeding cage into several small square spaces. Since crayfish are burrowing aquatic creatures and prefer relatively small spaces, this design also solves the problem of crayfish easily piling up and crowding inside the cage, affecting their growth space and health. It also allows for the rational and full utilization of the internal space of the breeding cage. Furthermore, the detachable modular design divides the breeding cage into several combinable modules. If any module is damaged, it can be individually removed for repair or replacement, facilitating later cleaning, maintenance, and replacement, thus reducing maintenance and replacement costs. Moreover, the detachable double-layer design allows for easy harvesting of crayfish at harvest time by simply lifting the harvesting cage 6, increasing harvesting efficiency. Finally, the detachable perforated plate 2 allows for adjustment of the hole diameter according to the size of the crayfish. When raising crayfish larvae, the detachable perforated plate 2 can be installed to prevent the larvae from escaping through the holes. This design is suitable for raising crayfish of different ages.
