[0052] The working principle and use process of the present invention are as follows: before the device is used, the on-site personnel fill the multiple stirring shafts 420 with phytoplankton particles. Then, when the device is put into actual use, the water tank 320 is first filled with filtered seawater, and then the external PLC opens the multiple solenoid valves 330. Then, the seawater in the water tank 320 is diverted into the multiple culture boxes 210. Then, the solenoid valves 330 are closed. Then, the on-site personnel start the electric heater 220. The electric heater 220 raises the water temperature in the culture box 210 until the water temperature reaches 20°-30°. Then, male oysters are placed in the culture box 210. and female oysters, and then at the appropriate water temperature, the male and female oysters blend with each other, and then oyster seedlings will be produced in about 16 hours, and then in order to allow these seedlings to eat, the external PLC will open the solenoid valve 1 310 and the solenoid valve 2 330, and then the seawater in the water tank 320 will rush into the interior of the incubator 210, and then the oyster seedlings mixed with the seawater will be diverted from the position of the solenoid valve 1 310 into the interior of multiple nutrient tanks 340, and then after the seawater level in the nutrient tank 340 reaches a certain height, the external PLC will close the solenoid valve 1 310 and the solenoid valve 2 330 again, and at the same time it will start the electric push rod 440, the electric push rod The rod 440 passes through the tooth plate 450 to make the stirring shaft 420 with the gear ring 430 rotate clockwise and counterclockwise, and then the phytoplankton particles in the stirring shaft 420 flow into the nutrient tank 340 from the through hole 460. Then, the stirring shaft 420 stirs the phytoplankton particles to fill every position in the nutrient tank 340, which is convenient for oysters to eat. During this period, whether it is the production of oyster seedlings or the feeding of oysters, the oxygen supply machine 520 is in working condition. It keeps the male and female oysters in the incubator 210 alive through the oxygen pipe 1 530, and then through the oxygen pipe 2 540, the oxygen supply machine 520 Oxygen rushes into the stirring shaft 420, and then the oxygen is filled in the nutrient tank 340 along with the outflowing phytoplankton particles, thereby ensuring the survival rate of the oyster seedlings. After that, the seedlings in the nutrient tank 340 are waited for six weeks. At this time, the size of the oyster seedlings will increase to about one millimeter. After graded cultivation, this type of oysters grow smoothly. Then this batch of seedlings leaves the hatchery and enters the breeding process. In the external breeding container, workers will add seawater and natural phytoplankton to cultivate the seedlings for six months, and then the size of the seedlings will increase four times. At this time, the workers can safely transfer the seedlings to the nearby port and then enter the sea for cultivation.
