During the watering process, since the cultivation tank 2 rotates with the transmission device, there is a time difference when the two cultivation tanks 2 pass the highest point of the transmission device. During this period of time, if the water pump 45 is always turned on, the water flow cannot be sprayed in the cultivation tank 2, and the water flow remains outside the cultivation tank 2, which not only wastes water resources but also causes water on the ground to affect the cultivation environment; if the water pump 45 is only turned on during watering, the cultivation tank 2 stops intermittently, and the repeated switching causes the accumulation of electric charge, which greatly damages the water pump 45;

When the water outlet structure provided by the present invention is in use, the water pump 45 is turned on, and the water pump 45 transports the water in the water tank 44 to the rotating tube 41 through the water inlet pipe 42, and then transports the water to the water delivery pipe 4 through the rotating tube 41, and finally sprays the water on the seedling tray 24 through the atomizing nozzle 43; during the rotation of the cultivation tank 2, the rotating tube 41 is driven to rotate by the driving component, the fixed frame 491 is driven to rotate by the rotating tube 41, and the connecting rod 493 and the blocking plate 492 are driven to rotate by the fixed frame 491.

During the rotation process, the chain 12 drives the cultivation trough 2 to rotate through the connecting assembly, so as to achieve watering and lighting of each cultivation trough 2; and the temperature of the cultivation rack 1 placed in the greenhouse is different above and below, and the temperature environment of corn seedlings at different heights can be adjusted by adjusting up and down.

As shown in Figures 2 and 7, the driving assembly includes a first rotating wheel 48, a second rotating wheel 49, a first gear 46 and a second gear 47; the first gear 46 is fixedly connected to one end of the upper transmission shaft 14; the second gear 47 is rotatably connected to the cultivation frame 1 through a rotating shaft; the first gear 46 is meshed with the second gear 47; the first rotating wheel 48 is fixedly connected to the rotating shaft and is arranged on the outside of the second gear 47; the second rotating wheel 49 is fixedly connected to the outside of the rotating tube 41, and a transmission belt 410 is sleeved between the first rotating wheel 48 and the second rotating wheel 49.

When the driving assembly provided by the present invention is in use, the sprocket 11 drives the connected transmission shaft 14 to rotate during the rotation process, drives the first gear 46 to rotate through the transmission shaft 14, drives the second gear 47 to rotate through the first gear 46, drives the rotating shaft and the first rotating wheel 48 to rotate through the second gear 47, drives the transmission belt 410 to rotate through the first rotating wheel 48, drives the second rotating wheel 49 to rotate through the transmission belt 410, drives the rotating tube 41 to rotate through the second rotating wheel 49, and drives the fixed frame 491 to rotate through the rotating tube 41, thereby connecting the rotation of the breeding trough 2 and the rotation of the sealing plate 492 together, so as to facilitate the regular rotation between the breeding trough 2 and the sealing plate 492.

As shown in FIG. 7 , the number of teeth of the first gear 46 is ten times the number of teeth of the second gear 47 , and the circumference of the first rotating wheel 48 is the same as that of the second rotating wheel 49 .

When the first gear 46 and the second gear 47 provided by the present invention are in use, the number of teeth of the first gear 46 is ten times the number of teeth of the second gear 47, thereby ensuring that the number of turns of the second gear 47 is ten times the number of turns of the first gear 46; the first rotating wheel 48 and the second rotating wheel 49 have the same circumference, ensuring that the number of turns of the first rotating wheel 48 and the second rotating wheel 49 are the same, so that the cultivation tank 2 changes a position and the sealing plate 492 rotates one circle to intermittently discharge water.

When the mounting frame 21 provided by the present invention is in use, the triangular shape improves the stability of the cultivation trough 2, and is easy to replace through bolt connection. When the chain 12 drives the mounting frame 21 to move through the support frame 22, the cultivation trough 2 is always kept vertically downward without affecting the cultivation; there are ten connecting components, which are evenly arranged on the outside of the chain 12.

As shown in Figures 5 and 6, the bottom of the cultivation trough 2 is fixedly connected with an inclined plate 242; the cultivation trough 2 is slidably connected with a permeation plate 241, and the permeation plate 241 is arranged above the inclined plate 242; the top of the permeation plate 241 is provided with a seedling tray 24; the bottom of the seedling tray 24 is provided with a permeation hole; the bottom of the inclined plate 242 is connected and fixedly connected with a drain pipe 25, and the drain pipe 25 is installed with a solenoid valve.

When the infiltration plate 241 provided by the present invention is in use, corn is cultivated in the seedling tray 24 through nutrient soil, which is convenient for taking out the corn seedlings for cultivation. The bottom of the seedling tray 24 flows excess water into the inclined plate 242 through the infiltration holes. After a period of time, the solenoid valve is controlled to open, and the water in the cultivation tank 2 is discharged through the drain pipe 25.

As shown in Figures 4 to 6, two first screw rods 26 and two second screw rods 27 are respectively threadedly connected to the side walls of the permeation plate 241; the outer sides of the first screw rods 26 are fixedly connected to the first rotating wheel 261; the outer sides of the second screw rods 27 are fixedly connected to the second rotating wheel 271 and the third rotating wheel 272, and the first belt 262 is sleeved between the second rotating wheel 271 and the first rotating wheel 261; the second belt 273 is sleeved between the third rotating wheels 272; and the top of one of the first screw rods 26 is fixedly connected to a rotating block 29.

The first screw rod 26 and the second screw rod 27 provided by the present invention are convenient for lifting and lowering the infiltration plate 241 when in use. When raising seedlings, the infiltration plate 241 is too high and the seedling tray 24 is unstable. After the seedlings are raised, the seedling tray 24 is too low and it is inconvenient to remove the seedling tray 24. Therefore, it is necessary to adjust the position of the seedling tray 24 by lifting and lowering the infiltration plate 241. By rotating the rotating block 29, the rotating block 29 drives the first screw rod 26 to rotate, and the first screw rod 26 drives the first rotating wheel 261 to rotate, and the first rotating wheel 261 drives the first belt 262 to rotate, and the first belt 262 drives the second rotating wheel 271 to rotate.

When the photoelectric switch 1 28 and the photoelectric switch 2 51 provided by the present invention are in use, when it is necessary to discharge the water at the bottom of the cultivation tank 2, the hot air computer program controls the photoelectric switch 1 28 and the photoelectric switch 2 51 to open, and when the cultivation tank 2 rotates in a circle along with the chain 12, when the photoelectric switch 1 28 and the photoelectric switch 2 51 come into contact, the current of the photoelectric switch 1 28 is connected with the current of the photoelectric switch 2 51, so that the current of the photoelectric switch 1 28 is energized, and the photoelectric switch 1 28 controls the solenoid valve to open through an electrical signal. When the solenoid valve is opened, excess water in the cultivation tank 2 is discharged from the drain pipe 25. As the cultivation tank 2 continues to rotate, the photoelectric switch 1 28 and the photoelectric switch 2 51 are separated, the photoelectric switch 1 28 is temporarily powered off, and the solenoid valve is closed until the next photoelectric switch 1 28 and the photoelectric switch 2 51 come into contact.

As shown in Figure 1, a water trough 6 is fixedly connected to the bottom of the cultivation rack 1; the bottom end of the water trough 6 is connected and fixed to one end of a water outlet pipe 61, and the other end of the water outlet pipe 61 passes through the cultivation rack 1 and is connected and fixed to the water tank 44. A control valve is installed on the water outlet pipe 61.

When the water trough 6 provided by the present invention is in use, the water in the cultivation trough 2 sometimes cannot be absorbed by the nutrient soil in time, and the excess water flows through the infiltration holes and the infiltration plate 241 to the inclined plate 242, and is finally discharged to the water trough 6 through the drain pipe 25. When the water in the water trough 6 accumulates to a certain level, the control valve is opened, and the water in the water trough 6 is discharged to the water tank 44 through the outlet pipe 61 for reuse.

As shown in FIG. 3 , four fluorescent lamps 3 are fixedly connected between the two inner side walls of the cultivation rack 1 , and the fluorescent lamps 3 are evenly arranged on the inner side of the chain 12 .

When in use, the fluorescent lamp 3 provided by the present invention is used to provide illumination and promote photosynthesis of corn seedlings. It is arranged on the inner side of the chain 12. When the cultivation tank 2 rotates, the corn seedlings on both sides of the cultivation tank 2 can receive illumination, thereby achieving the function of uniform light reception.

Working principle: when watering or lighting is needed, the motor 13 needs to be turned on, the motor 13 drives the transmission shaft 14 to rotate through the output shaft, the transmission shaft 14 drives the sprocket 11 to rotate, the sprocket 11 drives the chain 12 to rotate, and the chain 12 drives the other end of the sprocket 11 to rotate, so as to achieve the continuity of the rotation of the whole device. During the rotation process, the chain 12 drives the cultivation tank 2 to rotate through the connecting assembly, so as to achieve watering and lighting of each cultivation tank 2; and the temperature of the cultivation rack 1 placed in the greenhouse is different above and below, and the temperature environment of corn seedlings at different heights can be adjusted by adjusting it up and down;

During the rotation process, the sprocket 11 drives the connected transmission shaft 14 to rotate, drives the first gear 46 to rotate through the transmission shaft 14, drives the second gear 47 to rotate through the first gear 46, drives the rotating shaft and the first rotating wheel 48 to rotate through the second gear 47, drives the transmission belt 410 to rotate through the first rotating wheel 48, drives the second rotating wheel 49 to rotate through the transmission belt 410, drives the rotating tube 41 to rotate through the second rotating wheel 49, and drives the fixing frame 491 to rotate through the rotating tube 41, thereby connecting the rotation of the cultivation tank 2 and the rotation of the blocking plate 492 together, so as to form a regular rotation between the cultivation tank 2 and the blocking plate 492;

Turn on the water pump 45, and the water pump 45 transports the water in the water tank 44 to the rotating tube 41 through the water inlet pipe 42, and then transports the water to the water delivery pipe 4 through the rotating tube 41, and finally sprays the water on the seedling tray 24 through the atomizing nozzle 43; during the rotation of the cultivation tank 2, the rotating tube 41 is driven by the driving component to rotate, the fixed frame 491 is driven to rotate through the rotating tube 41, and the connecting rod 493 and the blocking plate 492 are driven to rotate through the fixed frame 491. Through the cooperation of the first gear 46 and the second gear 47, the rotation process of the blocking plate 492 and the blocking plate 492 has a certain regularity. The second gear 47 rotates one circle, and the fixed frame 491 drives the blocking plate 492 to rotate one circle, and the cultivation tank 2 rotates from this position to the next cultivation tank 2; two blocking plates 492 are symmetrically provided, and the arc length of the cross section is one-fourth of the circumference of the water pipe 4, so when the top blocking plate 492 moves to the highest point, the blocking plate 492 gradually rotates to release the blockage of the atomizing nozzle 43 and sprays. During the process of the blocking plate 492 rotating from the highest point to the other side, the blocking plate 492 gradually rotates to block the atomizing nozzle 43, thereby completing one water discharge, and continuing to rotate, through the cooperation of the blocking plate 492 and the atomizing nozzle 43, the function of intermittent water spraying is realized; the water pump 45 is used as the main switch. When the seedlings are young, less water is required, and the water pump 45 is turned on for a short time. As the corn seedlings grow, the water pump 45 is turned on for a longer time to meet the water required for seedling cultivation;

During seedling raising, the permeable plate 241 is too high and the seedling tray 24 is unstable. After the seedling raising is completed, the seedling tray 24 is too low to be convenient to remove the seedling tray 24. Therefore, the position of the seedling tray 24 needs to be adjusted by lifting the permeable plate 241.
