[0037] When the hot gas circulation is carried out in the circulation pipe 9 of the application, the gas will push the driving column 16 to move in the circulation pipe 9, at this time, when the driving column 16 passes through the magnetic ring 13, the driving column 16 will drive the magnetic ring 13 to move upward, so as to make the driving blade 15 rotate by the resistance of the water in the water tank 5, after the driving column 16 completely passes through the magnetic ring 13, the magnetic ring 13 will move downward due to the gravity, when the driving column 16 passes through the heating tank 8, the guide rod 19 will be inserted into the circular hole 17 to guide the driving column 16, because of the gravity of the driving column 16, the avoiding groove 18 of the driving column 16 will always move downward when the driving column 16 is in the heating tank 8, so that the driving column 16 can smoothly pass through the supporting rod 20.

[0038] A group of sliding grooves 22 are arranged on the side wall of the driving column 16, the inner wall of the sliding groove 22 is slidably connected with a cylinder 21, the first spring is fixedly connected between the cylinder 21 and the inner wall of the sliding groove 22, the rotating shaft is rotatably connected to the side of the cylinder 21 away from the first spring, and the gap exists between the side wall of the driving column 16 and the inner wall of the circulation pipe 9; the circulation pipe 9 in the application has a bending part, in order to prevent the driving column 16 from being stuck in the bending part of the circulation pipe 9, when the driving column 16 passes through the bending part of the circulation pipe 9, the cylinder 21 will be pushed by the pipe wall of the bending part to slide into the sliding groove 22, so that the driving column 16 can smoothly pass through, and at the same time, the rotating shaft can be attached to the pipe wall due to the pushing force of the first spring, so that the friction between the rotating shaft and the pipe wall is reduced, so that the driving column 16 can move more smoothly.

[0039] The connecting frame 23 is fixedly connected to the side of the box body 1 close to the water tank 5, the water tank 5 is fixed on the inner wall of the connecting frame 23, the through groove 24 is arranged on the side of the box body 1 close to the water tank 5, the first sealing plate 25 for sealing the through groove 24 is slidably connected to the inner wall of the connecting frame 23, the second sealing plate 26 is arranged on the connecting frame 23, the second sealing plate 26 is used for sealing the end of the connecting frame 23 away from the box body 1, and the moving assembly for controlling the first sealing plate 25 to move is arranged on the outer side wall of the box body 1; when the water in the water tank 5 is heated, the first sealing plate 25 can be controlled to move downward by the moving assembly to seal the through groove 24, after the water is heated, the first sealing plate 25 can be moved upward, at this time, the through groove 24 is in communication with the inner wall of the connecting frame 23, at this time, the water in the water tank 5 can be heat-preserved by the inner temperature of the box body 1, so as to improve the heat-preservation effect of the water.

[0040] The movable component includes a rotating rod 28 that rotates with the side wall of the housing 1. A first connecting line 27 is fixedly connected to the surface of the rotating rod 28. The end of the first connecting line 27 away from the rotating rod 28 is fixedly connected to a first sealing plate 25. A set of second springs is fixedly connected between the top surface of the first sealing plate 25 and the inner wall of the connecting frame 23. A motor that drives the rotating rod 28 to rotate is provided inside the housing 1. In this application, the rotating rod 28 is controlled by the motor to rotate clockwise. At this time, the first connecting line 27 will be wound around the rotating rod 28. At this time, the first connecting line 27 will pull the first sealing plate 25 to seal the through groove 24. When the rotating rod 28 is controlled by the motor to rotate in reverse, the first connecting line 27 will be released from the rotating rod 28. At this time, the second spring will pull the first sealing plate 25 to reset, so that the first sealing plate 25 no longer seals the through groove 24.

[0041] A push plate 30 is slidably connected to the inner wall of the water tank 5, and a slide rod 32 is slidably connected to the top surface of the water tank 5. A connecting rod 31 is fixedly connected to the top surface of the connecting frame 23. The bottom end of the connecting rod 31 is open. The slide rod 32 is slidably and sealed to the inner wall of the connecting rod 31. A third spring is fixedly connected between the top end of the slide rod 32 and the inner wall of the connecting rod 31. The moving component can be used to control the movement of the slide rod 32. When the solenoid valve in this application is opened, the water in the water tank 5 will be discharged from the drain pipe 6. At this time, the slide rod 32 can be controlled to move downward by the moving component, so that the slide rod 32 pushes the push plate 30 downward. At this time, the push plate 30 will push the water in the water tank 5 to pressurize the water. When the water is sprayed out from the nozzle 7, the spraying area can be increased to improve the uniformity of irrigation of the seedling tray. At the same time, the increased water pressure can also prevent impurities in the water from clogging the nozzle 7.

[0042] The movable component also includes a second connecting line 29 fixedly connected to the surface of the rotating rod 28. The end of the second connecting line 29 away from the rotating rod 28 is fixedly connected to a second sealing plate 26. The second sealing plate 26 is slidably connected to the bottom surface of the connecting frame 23. A set of support plates is fixedly connected to the side wall of the second sealing plate 26. A fourth spring is fixedly connected between the top surface of the support plate and the connecting frame 23. A connecting block 34 is fixedly connected to the top surface of the inner wall of the connecting frame 23. The bottom end of the connecting block 34 is open. A moving plate 35 is slidably connected to the inner wall of the connecting block 34. A fifth spring is fixedly connected between the top surface of the moving plate 35 and the inner wall of the connecting block 34. The elasticity of the fifth spring is less than that of the third spring. A conduit 33 communicates between the connecting block 34 and the connecting rod 31.

[0043] When the solenoid valve in this application is opened, the output end of the motor rotates clockwise. At this time, the second connecting line 29 will be released from the rotating rod 28. The second sealing plate 26 will move upward under the push of the fourth spring, causing the second sealing plate 26 to push the moving plate 35. The moving plate 35 will then push the gas in the connecting block 34 from the conduit 33 into the connecting rod 31. The gas will then push the slide rod 32, causing the slide rod 32 to push the push plate 30, thereby pressurizing the water in the water tank 5. When it is necessary to add water to the water tank 5, the rotating rod 28 can be reversed. At this time, the second connecting line 29 will pull the second sealing plate 26 downward, so that the second sealing plate 26 no longer pushes the moving plate 35. Then the third spring will pull the slide rod 32, so that the height of the push plate 30 is higher than the liquid outlet of the liquid inlet pipe 10. The moving plate 35 will be reset under the push of the fifth spring.

[0044] Example 2: Figure 7 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a hollow groove 38 is provided in the push plate 30, and multiple sets of through holes 36 communicating with the hollow groove 38 are provided on the bottom surface of the push plate 30. An inlet hole 37 communicating with the hollow groove 38 is provided on the side of the push plate 30 near the liquid inlet pipe 10. When the nutrient solution in this application enters the water tank 5, the push plate 30 can be controlled to move downward so that the through hole 36 communicates with the liquid outlet end of the liquid inlet pipe 10. At this time, the nutrient solution can enter the hollow groove 38 from the through hole 36 and then be evenly discharged into the water in the water tank 5 from the through hole 36 to improve the uniformity of the nutrient solution in the water. After the nutrient solution is discharged, the push plate 30 can be allowed to continue to move downward so that the water in the water tank 5 can enter the hollow groove 38 from the liquid outlet. Then the push plate 30 can be allowed to move upward so that the nutrient solution remaining in the hollow groove 38 can be discharged from the through hole 36 with the water flow.

[0045] like Figure 8 As shown, a rice breeding method using the aforementioned rice breeding apparatus includes the following steps:

[0046] S1: Rice is planted in a seedling pot, and then the seedling pot is placed in the box 1. The heater 12 and the circulating fan 11 allow the hot air to circulate in the circulation pipe 9 so that the box 1 is kept at a uniform temperature. The seeds are then illuminated by the daylight lamp 4.

[0047] S2: Seal the through groove 24 with the first sealing plate 25, and then inject the nutrient solution and water into the water tank 5 from the liquid inlet pipe 10. At this time, heat the water in the water tank 5 with the help of the circulation pipe 9. After the water is heated, let the first sealing plate 25 stop sealing the through groove 24.

[0048] S3: By opening the solenoid valve, water is discharged from the drain pipe 6 and then sprayed out from the nozzle 7. When the water is sprayed out, the push plate 30 pushes the water in the water tank 5 to pressurize the water and assist in its discharge.

[0049] Working principle: By placing seeds into a pre-filled seedling tray with planting soil, and then placing the tray above guide rail 3, the heater 12 is activated, and the circulating fan 11 is also activated. At this time, air exits from the left side of the circulation pipe 9 and enters from the right side, allowing hot air to circulate within the circulation pipe 9 to maintain a preset constant temperature within the chamber 1. The temperature sensor 2 adaptively controls the heater 12 to adjust the heating temperature when it senses temperature changes. When watering is needed for seed cultivation, water can be added to the water tank 5 through the liquid inlet pipe 10. The circulation pipe 9 is located inside the water tank 5. At this time, the circulation pipe 9 can heat the water in the water tank 5, so that the water temperature in the water tank 5 is close to the temperature inside the box 1. Then, the solenoid valve can be opened to allow the water in the water tank 5 to be discharged from the drain pipe 6 and then sprayed from the nozzle 7 into the seedling tray to irrigate and cultivate the seeds. Irrigating the seeds with water that is close to the temperature inside the box 1 can avoid disrupting the original temperature control balance inside the cultivation box, improve the uniformity of seed germination and the stability of seedling growth. The daylight lamp 4 can illuminate the seeds to assist in rice breeding.

[0050] During rice breeding, nutrient solution can be added to water tank 5 through inlet pipe 10 and mixed with water. The nutrient solution can assist in breeding. The drive assembly can drive magnetic ring 13 to move up and down. When magnetic ring 13 moves, drive blade 15 rotates due to the resistance of the water in water tank 5. Drive blade 15 then stirs the water in water tank 5 to aid in mixing the nutrient solution with the water. Simultaneously, when heating the water in water tank 5, it can also stir the water to improve the heating effect. When hot air circulates in circulation pipe 9, the gas pushes drive column 16 to move within circulation pipe 9. When drive column 16 passes magnetic ring 13, it drives magnetic ring 13 upwards, thus using the resistance of the water in water tank 5 to rotate drive blade 15. After passing through all three points, the magnetic ring 13 will move downwards due to gravity. When the drive column 16 passes through the heating box 8, the guide rod 19 will be inserted into the round hole 17 to guide the drive column 16. Due to the gravity of the drive column 16, the clearance groove 18 will continue to move downwards when the drive column 16 is in the heating box 8, allowing the drive column 16 to pass smoothly through the support rod 20. The circulation tube 9 in this application has a bend. In order to prevent the drive column 16 from getting stuck at the bend of the circulation tube 9, when the drive column 16 passes through the bend of the circulation tube 9, the cylinder 21 will be pushed by the tube wall at the bend and slide into the slide groove 22, allowing the drive column 16 to pass smoothly. At the same time, the rotating shaft can be in contact with the tube wall due to the push of the first spring. The friction between the rotating shaft and the tube wall can be reduced, thereby allowing the drive column 16 to move more smoothly.

[0051] When the water in the water tank 5 is heated, the first sealing plate 25 can be moved downward by the moving component to seal the through groove 24. After the water is heated, the first sealing plate 25 can be moved upward, and the through groove 24 will be connected to the inside of the connecting frame 23. At this time, the water in the water tank 5 can be kept warm by the internal temperature of the tank body 1, thereby improving the heat preservation effect of the water. In this application, the rotating rod 28 is controlled by the motor to rotate clockwise. At this time, the first connecting wire 27 will be wound around the rotating rod 28. The first connecting wire 27 will pull the first sealing plate 25 to seal the through groove 24. When the rotating rod 28 is controlled by the motor to rotate in reverse, the first connecting wire 27 will be released from the rotating rod 28. At this time, the second spring will pull the first sealing plate 25 to reset, so that the first sealing plate 25 no longer seals the through groove 24.

[0052] When the solenoid valve in this application is opened, the water in the water tank 5 will be discharged from the drain pipe 6. At this time, the sliding rod 32 can be moved downward by the moving component, so that the sliding rod 32 pushes the push plate 30 downward. At this time, the push plate 30 pushes the water in the water tank 5 to pressurize the water, so that when the water is sprayed out from the nozzle 7, the spraying area can be increased, thereby improving the uniformity of irrigation to the seedling tray. At the same time, the increased water pressure can also prevent impurities in the water from clogging the spray holes of the nozzle 7. When the solenoid valve in this application is opened, the motor... When the output end rotates clockwise, the second connecting line 29 will loosen on the rotating rod 28. At this time, the second sealing plate 26 will move upward under the push of the fourth spring, causing the second sealing plate 26 to push the moving plate 35. The moving plate 35 will then push the gas in the connecting block 34 from the conduit 33 into the connecting rod 31. The gas will then push the slide rod 32, causing the slide rod 32 to push the push plate 30, thereby pressurizing the water in the water tank 5. When it is necessary to add water to the water tank 5, the rotating rod 28 can be reversed. At this time, the second connecting line 29 will pull the second sealing plate 26 downward, so that the second sealing plate 26 no longer pushes the moving plate 35.
