[0002] Freshwater aquaculture refers to the use of ponds, reservoirs, lakes, rivers and other inland waters (including brackish water) to raise and breed aquatic economic animals (fish, shrimp, crab, shellfish, etc.) and aquatic economic plants. It is an important part of the inland aquaculture industry. When breeding mandarin fish, in addition to feeding feed, animal livers are also used for feeding. The nutrients in animal livers have a positive effect on the growth and development of fish fry, especially for fish fry in the young fish stage.

[0003] According to a Chinese patent with the publication number "CN217038489U", a freshwater fish farming equipment is disclosed. The top of the box is recessed inward to provide a storage space. The storage space can be used to hold farming water. At the same time, the storage space can prevent a large amount of farming water from being lost, thereby avoiding the waste of water resources. At the same time, the storage space can also provide a living space for fish. The farmer can stand on the observation platform, put fish food into the storage space and observe the growth of the fish, thereby solving the technical problem of large water resource consumption in traditional pond aquaculture in the prior art.

[0004] When using animal liver to feed mandarin fish fry, if the animal liver is large in size, it is not convenient for the mandarin fish fry to swallow, which will affect the growth and development of the mandarin fish fry. Therefore, a breeding box for freshwater fish breeding is proposed to solve the above-mentioned problems. Summary of the invention

The material box 401 is fixedly connected to the top of the feeding tank 2, and a feeding pipe 402 is fixedly connected to the bottom of the material box 401. The feeding pipe 402 penetrates into the interior of the feeding tank 2 and extends downward.

[0042] A discharge port 403 is provided on the front of the feed pipe 402, and the bottom of the feed pipe 402 is in a blocked state. The top inner wall of the discharge port 403 is rotatably connected to a rotating rod 404, and four push plates 405 are fixedly connected to the rotating rod 404. The discharge port 403 is blocked by setting the push plates 405, and the top stirring rod 3011 is in contact with the push plate 405. During the rotation of the top stirring rod 3011, the push plate 405 is in contact with the push plate 405, and the push plate 405 and the rotating rod 404 are pushed to rotate. At this time, the rotating push plate 405 will push the bile acid in the feed pipe 402 out and sprinkle it into the feeding tank 2, thereby expanding the spreading range of the bile acid and increasing the mixing uniformity of the bile acid and the animal liver.

At this time, the rotating push plate 405 will push out the bile acid in the feeding pipe 402 and sprinkle it into the feeding tank 2, thereby expanding the spreading range of the bile acid and increasing the mixing uniformity of the bile acid and the animal liver. The bile acid and the animal liver are mixed and stirred by the rotation of the stirring rod 3011. The bile acid can improve the digestion of fat in liver feed. The absorption rate is improved, thereby improving the nutritional value and utilization rate of the feed, making the animal liver more conducive to the consumption and digestion of the mandarin fish seedlings. Then the torsion spring 406 rebounds to drive the rotating rod 404 and the pushing plate 405 to return to their original positions, and the discharge port 403 is blocked to achieve uniform discharge. This is repeated to achieve uniform discharge of bile acid. When the bottom stirring rod 3011 rotates, it will contact the conical top block 4011 and push it downward, and the annular pushing block 4010 moves downward to push the animal liver in the gap into the crushing chamber to avoid clogging of the gap.

[0049] Working principle: The feeding tank 2 moves forward and drives the suction hopper 503 to move forward through the L-shaped rod 202. When the suction hopper 503 moves to the front, the liver residue and feces on the inner wall of the bottom of the breeding box 1 are shoveled off through the shovel 506 on the back. The suction hopper 503 moves to the front and drives the first triangular top block 508 on the front to move forward and contact with the second triangular top block 509 on the front, which will then be pushed down. The second triangular top block 509 on the front moves downward and drives the third slider 505 on the front to move downward. The third slider 505 on the front moves downward and drives the front The shovel 506 moves downward and contacts the bottom inner wall of the breeding box 1. At this time, the front circular elastic block 5011 will be stuck in the front circular groove 5010, and the third slider 505 and the back shovel 506 will be pulled up by the cable 507. Then, when the suction hopper 503 moves backward, the liver residues and feces adhered to the bottom inner wall of the breeding box 1 are shoveled off by the front shovel 506. This process is repeated repeatedly. The two shovels 506 can alternately shovel the liver residues and feces adhered to the bottom inner wall of the breeding box 1 when the suction hopper 503 moves back and forth.

[0050] See also Figure 1-11 On the basis of the above embodiment, in another embodiment of the present invention, a disinfection water tank 6 is fixedly connected to the front inner wall of the breeding box 1, which is used to purify and disinfect the water separated by the solid-liquid separator 501. The disinfection water tank 6 is connected to the solid-liquid separator 501 through a connecting pipe. A plurality of water outlet pipes 7 are fixedly connected to the bottom of the disinfection water tank 6. A plurality of water outlet holes 8 are opened at the bottom of the water outlet pipes 7. The purified and disinfected water flows into the breeding box 1 through the plurality of water outlet pipes 7 and the plurality of water outlet holes 8. The oxygen content in the water can be increased by increasing the contact degree between the water body and the air, thereby providing a good growth environment for the mandarin fish seedlings.
