[0024] Reference Figure 1-Figure 4 A seedling raising device comprises a seedling raising pot 1, an outer ring 2, a supporting column 3, a sewage discharge mechanism and an oxygenation mechanism. The bottom of the seedling raising pot 1 is designed to be conical to facilitate the discharge of pollutants. The outer ring 2 is sleeved on the outside of the seedling raising pot 1, and the seedling raising pot 1 is supported by three supporting columns 3. A drainage hole is provided at the bottom of the seedling raising pot 1, and is connected to a solenoid valve 21 through a bottom pipe 20 to control the discharge of sewage.
[0025] The sewage discharge mechanism includes a motor 10, a top plate 6, a rotating column 15, a No. 1 connecting rod 16, a scraper 17, a No. 2 connecting rod 18 and a perforated plate 19. The motor 10 is fixed on the top plate 6 and is fixedly connected to the top of the seedling tank 1 by bolts. The output shaft of the motor 10 passes through the top plate 6 and is connected to the rotating column 15. The two sides of the rotating column 15 are respectively connected to the No. 1 connecting rod 16 and the No. 2 connecting rod 18. The other ends of the No. 1 connecting rod 16 and the No. 2 connecting rod 18 are connected to the scraper 17. The scraper 1 7 is driven by the motor 10 to rotate along the inner wall of the seedling tank 1, scrape and push the pollutants to the conical bottom by the suction during drainage, and then discharge them through the bottom pipe 20 by opening the electromagnetic valve 21. The orifice plate 19 is arranged at the drainage hole. The hole of the orifice plate 19 is smaller than the size of the fry body to prevent the fry from being discharged, and the hole diameter of the orifice plate 19 is larger than the volume of the pollutants. At the same time, under the action of the controller, the rotation speed of the motor is relatively slow to prevent the fry from being damaged when scraping the inside of the tank.
[0026] The oxygenation mechanism includes an air pump 13 and an oxygen detector 5. The air pump 13 is fixed on the top plate 6, sucks air through the air inlet pipe, and injects oxygen into the seedling tank 1 through the air outlet pipe. The oxygen detector 5 is fixed on the outside of the seedling tank 1, detects the oxygen content in the tank, and is linked with the air pump 13 through the controller 14 to automatically adjust the oxygenation amount.
[0027] The present application can be used in the field of seedling cultivation, and can also be used in other fields applicable to the present application.

A No. 3 filter is provided at the heat dissipation hole 12 to prevent dust from entering. At the same time, a side plate 8 is provided to cover the heat dissipation hole 12 to reduce rainwater infiltration.
[0031] An observation window 4 is set on the front side of the seedling tank 1, which is made of transparent glass for observing the water quality and the condition of the fry. A drain pipe 9 is set on the outside of the seedling tank 1 for draining water when too much water is added. A No. 2 filter screen 22 is set inside the drain pipe 9 to prevent the fry from being discharged. A pipe cover is provided on the drain pipe 9 for closing the drain pipe 9.
