[0026] Example:

[0027] like Figure 1-4 As shown, this embodiment proposes a seedling watering device for greenhouse vegetables, including a base 1, a bracket 2 fixedly installed on the top of the base 1, uprights 3 fixedly connected to the top of the base 1 near the four corners, a support frame 4 slidably connected to the four uprights 3, a seedling box 5 set inside the support frame 4, an electric push rod 6 fixedly connected to the center of the top of the base 1, the push rod end of the electric push rod 6 fixedly connected to the center of the lower surface of the support frame 4, the lower surface of the seedling box 5 is in contact with the upper inner surface of the support frame 4, when the electric push rod 6 is activated, the support frame 4 and the seedling box 5 are moved upward by the electric push rod 6, and the seedling box 5 is adjusted to a suitable height position, a servo motor 7 fixedly installed at the center of the top of the bracket 2, when the servo motor 7 is activated, a connecting shaft 8 fixedly connected to the output end of the servo motor 7, a rotating plate 9 fixedly connected to the end of the connecting shaft 8 away from the servo motor 7, the servo motor 7 drives the connecting shaft 8 and the rotating plate 9 to rotate, a first connecting rod 10 is horizontally arranged on the bracket 2, both ends of the first connecting rod 10 are rotatably connected to the outer surface of the bracket 2 through bearings;

[0028] Two symmetrically distributed mounting plates 11 are fixedly sleeved on the first connecting rod 10. A second connecting rod 12 is fixedly connected between the two mounting plates 11. The second connecting rod 12 is located above the first connecting rod 10. A first connecting ring 13 is slidably sleeved on the second connecting rod 12. A guide rod 14 is vertically and movably inserted through the rotating plate 9. The lower end of the guide rod 14 is fixedly connected to the first connecting ring 13. The rotating plate 9 drives the guide rod 14 to move. When the rotating plate 9 rotates continuously, the first connecting ring 13 slides back and forth on the second connecting rod 12 through the guide rod 14. A conveying pipe 15 is provided below the first connecting rod 10. The guide rod 14 follows the rotation track of the rotating plate 9. While moving along the trajectory, the pipe itself moves up and down reciprocally. Two second connecting rings 16 are fixedly sleeved on the conveying pipe 15. A fixed rod 17 is fixedly connected between the second connecting ring 16 and the first connecting rod 10. Through the cooperation of the rotating plate 9, guide rod 14, first connecting ring 13, second connecting rod 12 and two mounting plates 11, the first connecting rod 10 can be driven to rotate reciprocally. Several nozzles 18 are installed on the conveying pipe 15. The nozzles 18 are located directly above the seedling box 5. Through the two fixed rods 17 and the two second connecting rings 16, the conveying pipe 15 swings in a fan shape. The multiple nozzles 18 move synchronously with the movement trajectory of the conveying pipe 15.

[0029] like Figure 1 and Figure 2 As shown, a mounting base 19 is fixedly connected to one side surface of the bracket 2, and a water pump 20 is fixedly installed on the upper surface of the mounting base 19. A liquid inlet port of the water pump 20 is fixedly connected to a liquid extraction pipe 21, and the lower end of the delivery pipe 15 is fixedly connected to the liquid outlet port of the water pump 20. When the water pump 20 is running, water is drawn in through the liquid extraction pipe 21, and after passing through the delivery pipe 15, the water is sprayed out through several nozzles 18, which can water the seedlings inside the seedling box 5.

[0030] like Figure 4 As shown, several drainage holes 22 are provided through the lower surface of the seedling box 5. Excess water inside the seedling box 5 can be discharged through the drainage holes 22, effectively preventing water accumulation inside the seedling box 5.

[0031] like Figure 1 and Figure 3 As shown, the two second connecting rings 16 and the two fixing rods 17 are symmetrically distributed about the central axis of the first connecting rod 10.

[0032] The working principle of the above embodiment is as follows: The electric push rod 6, servo motor 7, and water pump 20 are all electrically connected to an external control power supply. The liquid extraction pipe 21 is connected to an external water source. Then, the electric push rod 6 is started, which drives the support frame 4 and the seedling box 5 to move upward, adjusting the seedling box 5 to a suitable height position. Then, the water pump 20 and servo motor 7 are started. When the water pump 20 is running, water is drawn in through the liquid extraction pipe 21. After passing through the delivery pipe 15, the water is sprayed out through several nozzles 18 to water the seedlings inside the seedling box 5. When the servo motor 7 is running, it drives the connecting shaft 8 and the rotating plate 9 to rotate. The rotating plate 9 drives the guide rod 14 to move. During this process, since the first connecting rod 10 is rotatably connected to the bracket 2 through two bearings, and the first connecting ring... The first connecting ring 13 is slidably mounted on the second connecting rod 12. Therefore, when the rotating plate 9 continues to rotate, the first connecting ring 13 slides back and forth on the second connecting rod 12 through the guide rod 14. The guide rod 14 moves up and down while following the rotation trajectory of the rotating plate 9. Through the cooperation of the rotating plate 9, the guide rod 14, the first connecting ring 13, the second connecting rod 12 and the two mounting plates 11, the first connecting rod 10 can be driven to rotate back and forth. Through the two fixed rods 17 and the two second connecting rings 16, the conveying pipe 15 swings back and forth in a fan shape. Multiple nozzles 18 move synchronously with the movement trajectory of the conveying pipe 15. Thus, when watering the vegetable seedlings inside the seedling box 5, the uniformity of watering the seedlings can be improved, which is conducive to the normal growth of the seedlings.

[0033] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
