[0026] like Figure 1 and Figure 2 As shown, the first adjustment assembly includes two fixed blocks 5 fixedly connected to the top of the movable plate 4, the tops of the two fixed blocks 5 are rotatably connected to a rotating plate 7, the top of the rotating plate 7 is fixedly connected to a movable plate 6, a cylinder 8 is installed on the top of the movable plate 4, and the output shaft of the cylinder 8 is fixedly connected to the movable plate 4. The movable plate 6 at one end is driven downward by the output shaft of the cylinder 8, thereby tilting the water pipe placed on the top of the movable plate 6, and then adjusting the angle to adapt to different slopes.

[0027] like Figure 3 As shown, a threaded hole is provided inside the movable seat 12, and the movable seat 12 is threadedly matched with the bidirectional screw 10. By rotating the bidirectional screw 10 counterclockwise and clockwise, the two movable seats 12 move toward each other and in the opposite direction, and the height of the movable plate 4 supporting the water pipe is further adjusted.

[0028] like Figure 1 and Figure 2 As shown, sliding holes are provided at the four corners of the movable plate 4, the limiting rod 3 is movably sleeved in the limiting holes, and a positioning block 15 is provided on the top of the limiting rod 3.

[0031] Working principle:

[0032] When in use, connect the external power supply, and then place one end of the water delivery pipe on the top of the movable plate 6. When the water fills the pipe, the inside begins to expand. At this time, the limit plates 16 on both sides of the movable plate 6 limit the pipe to prevent the water inside the pipe from rolling down. When the height of the pipe needs to be adjusted during irrigation, drive the motor 11, so that the output shaft of the motor 11 drives the bidirectional screw 10 to rotate, and then the two moving seats 12 outside the bidirectional screw 10 move toward each other, and then drive the connecting rod 14 rotatably connected to the moving seat 12 to push the moving plate 4 to move upward along the outside of the limit rod 3. In the process of moving, the movable plate 6 drives the top water pipe to move upward, and the motor 11 is stopped when it reaches the appropriate height. When the water delivery pipe needs to be adjusted due to a slope, drive the cylinder 8, so that the output shaft of the cylinder 8 drives the movable plate 6 at one end to move downward, and then the water pipe placed on the top of the movable plate 6 is tilted, so that the angle can be adjusted to adapt to different slopes.
