[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0029] Please see Figures 1-4 This utility model provides a technical solution for a tilapia grading and farming device, including a farming box 1, a water plug 2, a water inlet pipe 3, an adjustment structure 4, an adjustment cylinder 401, a water inlet 402, an adjustment flap 403, a disinfection structure 5, a medicine cartridge 501, a buffer plate 502, a feeding slide plate 503, a feeding pipe 504, a fixed pulley 505, an adjustment pipe 506, a partition plate 6, a partition net 7, a sealing plate 8, a slot 9, a chute 10, a fixing bolt 11, a pull rope 12, a rotating shaft 13, and a return spring 14.
[0030] The working principle and usage process of this utility model are as follows: First, combined with... Figure 1 and Figure 4 As shown, the upper end of the sealing plate 8 has a "T"-shaped structure, and the height of the sealing plate 8 is greater than the internal depth of the partition plate 6. The sealing plate 8 and the partition plate 6 are fixedly connected by a fixing bolt 11. The sliding groove 10 is inclined on the inner wall of the breeding box 1, and the lower inner surface of the breeding box 1 is also inclined. The partition plate 6 forms a sliding structure inside the breeding box 1 through the sliding groove 10, and the partition plate 6 forms a disassembly structure on the breeding box 1 through the slot 9. The partition plate 6 is engaged with the inner wall of the breeding box 1 through the slot 9, and the sliding groove 10 allows for easy movement of the partition plate 6. 10. Slide left and right, from left to right, the aperture of the dividing mesh 7 on both sides of the dividing plate 6 decreases from large to small, which makes it easy to classify and raise tilapia of different sizes. It is convenient to use. The lower end of the interior of the breeding tank 1 is set at an angle. There is less water on the left side of the breeding tank 1. When the left dividing plate 6 is pushed to the left, the smaller fish will swim to the right side of the water until they stop swimming. Then, slide the sealing plate 8 down to close it with the dividing plate 6. This makes it easy to classify different fish, prevents them from swimming together and affecting the classification, improves work efficiency, and is convenient to use.
[0031] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the adjusting structure 4 includes an adjusting cylinder 401, a water inlet 402, and an adjusting flap 403. The adjusting cylinder 401 has water inlets 402 at both its upper and lower ends, which are connected to the water inlet pipe 3. The adjusting flap 403 is rotatably connected to the left side of the inner wall of the adjusting cylinder 401 via a rotating shaft 13. One end of a pull rope 12 is fixedly connected to the upper end of the adjusting flap 403. The disinfection structure 5 includes a medicine cartridge 501, a buffer plate 502, a discharge slide plate 503, a discharge pipe 504, a fixed pulley 505, and an adjusting pipe 506. The lower end of the medicine cartridge 501 is connected to the discharge pipe 506. 04. A regulating pipe 506 is connected to the middle of the cartridge 501. A fixed pulley 505 is rotatably connected to the connection between the regulating pipe 506 and the cartridge 501. A feeding slide plate 503 is rotatably connected to the right side of the inner wall of the cartridge 501 via a rotating shaft 13. A buffer plate 502 is inclinedly installed on the upper right inner wall of the cartridge 501. The lower end of the feeding slide plate 503 is connected to the other end of the pull rope 12. The regulating pipe 506 and the feeding pipe 504 are both connected to the left side wall of the regulating cylinder 401. The regulating pipe 506 and the feeding pipe 504 are respectively located on the upper and lower sides of the regulating flap 403. The tilting trajectory of the flap 403 inside the adjusting cylinder 401 via the rotating shaft 13 does not coincide with the opening of the feeding pipe 504. Both the feeding slide 503 and the adjusting flap 403 tilt at 90° via the rotating shaft 13. A return spring 14 is installed on the outer surface of the rotating shaft 13, which passes through the adjusting cylinder 401 and the outer end of the cartridge 501. Simultaneously, the tilting trajectory of the feeding slide 503 coincides with the opening of the adjusting pipe 506. The adjusting pipe 506, the cartridge 501, and the feeding pipe 504 form an "F" shape, and the feeding pipe 504 has an arc-shaped structure. After the process is completed, water is added to the inside of the breeding tank 1 through the water inlet pipe 3. The water flows into the inside of the adjustment structure 4 through the water inlet pipe 3. The gravity of the water presses down the adjustment flap 403. The adjustment flap 403 flips downward through the rotating shaft 13, which makes it easy for the adjustment flap 403 to pull down the pull rope 12. The pull rope 12 pulls down the feeding slide plate 503. When the feeding slide plate 503 flips down, the disinfectant inside the medicine cartridge 501 slides into the breeding tank 1 through the feeding pipe 504, realizing the automatic addition of disinfectant. It is quickly dissolved by water, which facilitates rapid and comprehensive disinfection.
[0032] The adjusting flap 403 and the feeding slide 503 are flipped by the rotating shaft 13. The elasticity of the return spring 14 makes it easy to keep the adjusting flap 403 and the feeding slide 503 parallel when they are not working. The buffer plate 502 inside the medicine cartridge 501 is set at an angle to slow down the falling speed of the disinfectant and prevent it from falling too fast. This reduces the concentration of disinfectant water inside the breeding tank 1 and makes it convenient for tilapia breeding. This is the working process of the tilapia grading breeding device.
[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
