Description

Technical Field

[0001] The utility model relates to the technical field of snakehead fish breeding, in particular to an automatic screening snakehead fish breeding device. Background Art

[0002] In order to meet the market demand for snakehead fish and increase its production, it is necessary to artificially propagate snakehead fish. However, currently, artificial propagation is often carried out through breeding ponds or artificial propagation equipment, but such breeding containers have the following disadvantages:

[0003] 1. Existing snakehead fish breeding containers have only one cavity, which cannot adjust and divide the snakehead fish's activity range according to their size. All snakehead fish gather together, and then the big fish will eat the small fish, which will affect the survival rate of the snakehead fish and thus affect the reproduction rate of the snakehead fish.

[0004] 2. The existing snakehead fish breeding containers have poor functionality and lack automatic water exchange and aeration functions, which will affect the breeding effect of snakehead fish.

[0005] 3. The structure of the snakehead fish breeding equipment is simple and difficult to disassemble and assemble quickly, which will affect the subsequent cleaning and maintenance of the equipment. Utility Model Content

[0009] Furthermore, positioning slides are respectively provided on both sides of the screening plate, and the inner side wall of the breeding box is provided with positioning grooves that slide in cooperation with the positioning slides.

[0010] Furthermore, a limit hanging ring is provided on the top of the above-mentioned screening plate, and a limit hook is provided on the top of the breeding box body that cooperates with the limit hanging ring. The locking connection between the limit hanging ring and the limit hook improves the firmness of the assembly of the screening plate and the breeding box body.

[0011] Furthermore, both sides of the screening plate are provided with rubber layers that are sealed with the breeding box.

[0012] Furthermore, the number of the above-mentioned sieve plates is at least 2, and the sieve hole sizes of all the sieve plates increase or decrease in sequence.

[0025] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0026] Please refer to Figure 1 and Figure 2 This embodiment provides an automatic screening and breeding device for snakehead fish, comprising: a breeding box 1, and an inlet pipe 4, an outlet pipe 6, and an air guide assembly disposed on the breeding box 1. A first screening plate 2 and a second screening plate 3 are vertically arranged inside the breeding box 1. The first screening plate 2 and the second screening plate 3 are spaced apart, dividing the interior of the breeding box 1 into three breeding chambers. A screen 14 is provided on each of the first screening plate 2 and the second screening plate 3. The sieve holes of the first screening plate 2 and the second screening plate 3 are of different sizes. The presence of the screen 14 allows smaller snakehead fish to pass through while intercepting larger ones. This automatically screens snakehead fish according to their size, preventing large fish from preying on smaller ones, improving their survival rate, and ultimately their reproduction rate. The inlet pipe 4 and the outlet pipe 6 have automatic water exchange functions, and the air guide assembly provides aeration and oxygenation, thereby improving the survival and reproduction rates of snakehead fish.

[0027] In this embodiment, the structures of the first screening plate 2 and the second screening plate 3 are the same. In other embodiments of the present invention, the number of screening plates can also be 1, 3, 4, 5, etc. When the number of screening plates is greater than or equal to 3, the sieve hole sizes of all screening plates are increased or decreased in sequence, so that the snakehead fish can be automatically screened according to volume.

[0028] Please refer to Figures 1 to 3The structures of the first screening plate 2 and the second screening plate 3 are consistent. In this embodiment, only the structure of the first screening plate 2 is described. Positioning slides 15 are respectively provided on both sides of the first screening plate 2, and positioning grooves 9 that slide with the positioning slides 15 are respectively provided on the inner side walls of the breeding box 1, so as to facilitate the rapid disassembly and assembly of the first screening plate 2. When the first screening plate 2 is matched with the breeding box 1, the bottom side of the first screening plate 2 contacts the inner bottom wall of the breeding box 1. A screen 14 is fixedly connected to the edge of the first screening plate 2. The size of the sieve holes of the screen 14 is adapted to the volume of the black snakehead, so that the corresponding black snakehead can pass through. A limiting hanging ring 13 is provided on the top of the first screening plate 2, and a limiting hook 10 is provided on the top of the breeding box 1. The limiting hook 10 can be hung on the limiting hanging ring 13, thereby quickly fixing the first screening plate 2.

[0029] Please refer to Figure 1 The outlet pipe 6 connects to the first breeding chamber, and the inlet pipe 4 connects to the last breeding chamber, allowing water to flow through all breeding chambers. Both the outlet pipe 6 and the inlet pipe 4 are equipped with a water pump 5, which is fixed to the outer wall of the breeding chamber 1. The ends of the outlet pipe 6 and the inlet pipe 4, away from the breeding chamber 1, are equipped with flanges 7 for quick connection to external pipes, allowing the entire breeding equipment to be quickly assembled and disassembled from the outside world.

[0030] Please refer to Figure 2 and Figure 4 The air guide component includes an aerator 16 and an air guide pipe 11. The aerator 16 is fixedly installed on the breeding box 1. The air guide pipe 11 is connected to the aerator 16. At the same time, the air guide pipe 11 is connected to all the breeding cavities, and an air guide nozzle 12 is provided at the connected position. The inside of the air guide nozzle 12 is provided with a waterproof and breathable membrane.

[0031] In order to improve the anti-sticking, wear-resistant and corrosion-resistant effects of the breeding box 1, in this embodiment, the inner wall of the box 1 is provided with a nano-ceramic anti-sticking layer.

[0032] In this embodiment, a liquid level sensor 8 is provided inside the breeding box 1 to replenish the water level, thereby enabling the water level to be adjusted by the water pump 5. In other embodiments of the present invention, the liquid level sensor 8 and the water pump 5 may also be connected to an external control box for automatic water level adjustment. The control box that controls the operation of the water pump 5 via the liquid level sensor 8 is prior art and will not be described in detail here.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
