[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2As shown in Figures 3 and 4, this embodiment proposes a sprinkler device for a greenhouse for planting Chinese medicinal herbs, including a greenhouse body 1. A fixed frame 2 is installed on the upper inner side of the greenhouse body 1. A main water pipe 3 is installed at the top of the fixed frame 2. A branch water pipe 4 is installed at the bottom of the main water pipe 3. A lifting mechanism is provided below the fixed frame 2. An installation plate 5 is installed at the bottom of the lifting mechanism. An adjustment mechanism is provided at the bottom of the installation plate 5. A movable plate 6 is installed at the bottom of the adjustment mechanism. A nozzle 7 is installed at the bottom of the movable plate 6. One end of the branch water pipe 4 is connected to one end of the nozzle 7.

[0020] The adjustment mechanism includes a mounting cavity 8, a first servo motor 9, a threaded rod 10, a threaded sleeve 11, a transmission rack 12, a transmission gear 13, a transmission rod 14, and a limiting structure. The mounting cavity 8 is installed at the bottom of the mounting plate 5. The first servo motor 9 is installed above the interior of the mounting cavity 8. The output end of the first servo motor 9 is fitted with a threaded rod 10. A threaded sleeve 11 is provided on the outer wall of the threaded rod 10. A transmission rack 12 is installed at the bottom of the threaded sleeve 11. A transmission gear 13 meshes with the lower part of the transmission rack 12. A transmission rod 14 is installed at the bottom of the transmission gear 13. The bottom end of the transmission rod 14 is connected to the top of the movable plate 6. In use, the mechanism is activated... The first servo motor 9 drives the threaded rod 10 to rotate. Therefore, under the limitation of the limiting rod 15 and the limiting sleeve 16, the threaded rod 10 drives the threaded sleeve 11 to move, which in turn drives the transmission rack 12 to move. Since the transmission rack 12 and the transmission gear 13 mesh with each other, the transmission gear 13 is driven to rotate. Then, under the limitation of the limiting rail 17 and the limiting block 18, the transmission gear 13 drives the transmission rod 14 to swing, which in turn drives the movable plate 6 and the nozzle 7 to swing, adjusting the angle of the nozzle 7 so that the nozzle 7 has a larger spraying range, thus making the spraying effect of the nozzle 7 better and greatly improving the practicality of the device in use.

[0021] The limiting structure includes a limiting rod 15, a limiting sleeve 16, a limiting rail 17, and a limiting block 18. The limiting rod 15 is installed above the threaded rod 10. A limiting sleeve 16 is provided on the outer wall of the limiting rod 15. The bottom end of the limiting sleeve 16 is connected to the top end of the threaded sleeve 11. A limiting rail 17 is installed at the bottom end of the mounting cavity 8. A limiting block 18 is provided inside the limiting rail 17. One end of the limiting block 18 is connected to one side of the transmission rod 14. The cross-section of the limiting rod 15 is smaller than the cross-section of the limiting sleeve 16. The limiting rod 15 and the limiting sleeve 16 form a sliding structure. The limiting rail 17 is arc-shaped, and the center of the limiting rail 17 and the center of the transmission gear 13 are on the same straight line. In use, the mutual cooperation between the limiting rod 15 and the limiting sleeve 16 can limit the movement of the threaded sleeve 11, making the threaded sleeve 11 more stable when moving. The mutual cooperation between the limiting rail 17 and the limiting block 18 can limit the rotation and swing of the transmission rod 14, making the transmission rod 14 more stable when moving.

[0022] The lifting mechanism includes a fixed cavity 19, a cavity 20, a second servo motor 21, a worm gear 22, a worm wheel 23, a drive gear 24, and a driven rack 25. The fixed cavity 19 is installed at the bottom of the fixed frame 2. The cavity 20 is installed on the lower side of one side of the fixed cavity 19. The second servo motor 21 is installed at the top of the cavity 20. The worm gear 22 is installed on one side inside the cavity 20. The output end of the second servo motor 21 is connected to one end of the worm gear 22. The worm wheel 23 meshes with one side of the worm gear 22. The drive gear 24 is coaxially installed at the rear end of the worm wheel 23. The driven rack 25 is provided inside the fixed cavity 19. The rack 25, with the driving gear 24 meshing with one side of the driven rack 25, is used when the second servo motor 21 is started to drive the worm 22 to rotate. Since the worm 22 and the worm wheel 23 mesh with each other, and the worm wheel 23 is coaxially connected with the driving gear 24, the worm wheel 23 drives the driving gear 24 to rotate. Since the driving gear 24 and the driven rack 25 mesh with each other, the driven rack 25 is moved, which in turn drives the nozzle 7 to move downward, making the nozzle 7 more effective when spraying Chinese herbal medicines, so that the soil can be fully irrigated, thereby greatly improving the comprehensiveness of the device in use.

[0023] Multiple nozzles 7 are arranged below the movable plate 6, and the multiple nozzles 7 are distributed at equal intervals below the movable plate 6. The design of multiple nozzles 7 can improve the working efficiency of the device.

[0024] Working principle: When spraying Chinese herbal medicines, the second servo motor 21 is activated to drive the worm gear 22 to rotate. Since the worm gear 22 and the worm wheel 23 are meshed with each other, and the worm wheel 23 is coaxially connected with the driving gear 24, the worm wheel 23 drives the driving gear 24 to rotate. Since the driving gear 24 and the driven rack 25 are meshed with each other, the driven rack 25 is moved, thereby driving the nozzle 7 to move downward. Then, the first servo motor 9 is activated to drive the threaded rod 10 to rotate. Therefore, under the limitation of the limiting rod 15 and the limiting sleeve 16, The threaded rod 10 drives the threaded sleeve 11 to move, which in turn drives the transmission rack 12 to move. Since the transmission rack 12 and the transmission gear 13 mesh with each other, the transmission gear 13 is driven to rotate. Under the limitation of the limiting rail 17 and the limiting block 18, the transmission gear 13 drives the transmission rod 14 to swing, which in turn drives the movable plate 6 and the nozzle 7 to swing, adjusting the angle of the nozzle 7. Then, the branch water pipe 4 transports the water inside the main water pipe 3 to the inside of the nozzle 7, and the nozzle 7 is used to spray and irrigate the herbs.
