[0031] Example 1:

[0032] like Figure 1 , Figure 2 and Figure 7As shown, an automatic irrigation device for rice seedling cultivation includes a pipe 1, a pipe 2 3 connected to the left end of the pipe 1 via a tube 10, a connector 2 rotatably connected to the outer wall of the pipe 2 3, the inner wall of the connector 2 being threadedly connected to the outer wall of the left end of the pipe 1, irrigation nozzles 4 being provided at the bottom of both the pipe 1 and the pipe 2 3, pressure balls 17 being connected inside the irrigation nozzles 4 via an adjusting plate 19, transmission rods 16 being rotatably connected inside both the pipe 1 and the pipe 2 3, knobs 9 being provided at the top of both the pipe 1 and the pipe 2 3, the top end of the transmission rod 16 being fixedly connected to the bottom end of the knobs 9, support members 8 being provided on the outer wall of both the pipe 1 and the pipe 2 3, lifting columns 7 being fixedly connected to the bottom of the support members 8, limit members 6 being provided inside the lifting columns 7, multiple limit holes being opened on the surface of the support column 5, the limit members 6 being located inside the limit holes, a lifting groove being opened inside the support column 5, and the lifting columns 7 being located inside the lifting groove.

[0033] Specifically, the sealing ring 11 is precisely installed onto the insertion pipe 10 to ensure its stable position and good sealing performance. Then, the sealing ring 14 is properly placed in the insertion groove of the pipe 1, laying the foundation for subsequent connection operations. When the water begins to flow inside the pipe 1 and the pipe 2, the water pressure generated by the water flow will act on the pressure ball 17 inside the irrigation nozzle 4. The force of the water pressure will push the pressure ball 17 downward, so that the water can flow out smoothly from the bottom of the irrigation nozzle 4, thereby irrigating the rice. The limiting member 6 is pulled out from the limiting hole on the support column 5. At this time, the lifting column 7 can move freely inside the support column 5. By adjusting the height of the lifting column 7, the height of the entire pipeline can be adjusted.

[0034] like Figure 5 and Figure 6 As shown, a threaded rod 18 is rotatably connected inside the pressure ball 17, and an adjusting plate 19 is threadedly connected to the outer wall below the threaded rod 18. The top of the adjusting plate 19 is connected to the outer wall of the pressure ball 17 through a spring 20. The spring 20 is sleeved on the outer wall of the threaded rod 18, and the top of the threaded rod 18 is fixedly connected to the bottom end of the transmission rod 16.

[0035] Specifically, by rotating knob 9, the connected transmission rod 16 rotates inside the pipe. The rotation of transmission rod 16 drives pressure ball 17 to rotate synchronously. The rotation of pressure ball 17 causes adjustment plate 19 to move up and down inside irrigation nozzle 4. The up and down movement of adjustment plate 19 causes spring 20 connected to it to deform, thereby changing the elastic potential energy of spring 20. Due to the change in elastic potential energy of spring 20, the force it exerts on pressure ball 17 will also change accordingly, thereby adjusting the water pressure on pressure ball 17. In this way, the operator can manually control the irrigation water flow by rotating knob 9 according to the actual growth of rice, ensuring that rice receives appropriate water supply at each growth stage and promoting its healthy growth.

[0036] Example 2:

[0037] As one of the optimized structural designs for Example 1, such as Figure 3 and Figure 4 As shown, the right end of pipe 2 3 is fixedly connected to the insertion tube 10, and the right end of pipe 2 3 is provided with a sealing ring 11. The sealing ring 11 is sleeved on the outer wall of the insertion tube 10. The left end of pipe 1 1 is provided with an insertion groove, and the inside of the insertion groove is provided with a sealing ring 2 14. The sealing ring 11 is located inside the insertion groove, and the right end of the sealing ring 11 is in contact with the left end of the sealing ring 2 14. The inside of the insertion groove is provided with a pressure plate 13, and the right end of the pressure plate 13 is fixedly connected to a connecting rod 12. The right end of the connecting rod 12 is connected to the inside of pipe 1 1 through a spring 15. The right end of the sealing ring 2 14 is in contact with the left end of the pressure plate 13.

[0038] Specifically, insert tube 10 is carefully inserted into the insertion groove of pipe 1. At this time, insert tube 10 will tightly press against sealing ring 14, and connector 2 will move to the left end of pipe 1. Then, by manually rotating connector 2, a stable connection is achieved between it and pipe 1. As connector 2 continues to rotate, pipe 3 will gradually penetrate into the insertion groove. During this process, pipe 3 will exert a squeezing effect on pressure plate 13. After pressure plate 13 is subjected to force, the pressure is transmitted to spring 15 through connecting rod 12, causing spring 15 to be compressed. Since spring 15 has an elastic force to restore its original shape, it will squeeze sealing ring 14 in the opposite direction, further enhancing its sealing effect. At the same time, when connector 2 is connected to pipe 1, pipe 1 will also squeeze sealing ring 11. In this way, the sealing of the connection between pipe 1 and pipe 3 is ensured from two aspects, effectively preventing water leakage when passing through the connection, thereby ensuring the stability of water pressure inside the pipe and avoiding the impact on irrigation effect due to water pressure drop caused by leakage.

[0039] Working principle: First, install sealing ring 11 onto the insertion tube 10, then place sealing ring 14 into the insertion groove on pipe 1. By inserting the insertion tube 10 into the insertion groove on pipe 1, the insertion tube 10 presses against sealing ring 14 within the groove. Simultaneously, connector 2 reaches the left end of pipe 1. By rotating connector 2, it connects to pipe 1. Continuing to rotate connector 2 causes pipe 2 3 to penetrate deeper into the insertion groove, thus squeezing pressure plate 13. This causes connecting rod 12 to compress spring 15 connected to it. Due to the force of spring 15, sealing ring 14 is squeezed. Furthermore, when connector 2 is connected to pipe 1, pipe 1 also squeezes sealing ring 11, thereby enhancing the sealing at the connection between pipe 1 and pipe 2 3, preventing leakage when water flows through, thus avoiding a drop in internal water pressure. When water flows through pipe 1 and pipe 3, the water pressure applies pressure to the pressure ball 17 inside the irrigation nozzle 4, pushing it down so that water flows out from the bottom of the irrigation nozzle 4 to irrigate the rice. By turning the knob 9, the transmission rod 16 connected to it rotates inside the pipe, thereby driving the pressure ball 17 to rotate. This causes the adjusting plate 19 to move up and down inside the irrigation nozzle 4, which causes the spring 20 on it to deform, thereby changing the elastic potential energy of the spring 20. This allows adjustment of the pressure ball 17's resistance to water pressure, enabling manual control of the water flow during irrigation to adapt to the irrigation amount at different growth stages of the rice. Furthermore, by pulling the limiting piece 6 out of the limiting hole on the support column 5, the lifting column 7 can move inside the support column 5, thereby adjusting the height of the pipe and effectively preventing the device from affecting the growth of the rice during irrigation.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
