[0002] When planting crops, crops often need to be sprayed to achieve water replenishment and cooling, but when spraying high height fruit trees, the installation height of the spraying device needs to have a certain height from the ground. The existing method is usually to bury the ground pipeline or build a fixed frame body in the air to install the spray head. However, regardless of which method, the height and spacing density of the spray head are fixed and cannot be adjusted according to the growth cycle and planting needs. In addition, it requires more consumables, which increases the use cost.

[0003] In the patent document with the application number "2024200332699", a kiwi seedling irrigation device is disclosed, which includes a main pipe, a plurality of internal thread connectors are arranged above the main pipe, a water distribution pipe is arranged above each internal thread connector, the number of water distribution pipes above the internal thread connectors is not less than two, and an irrigation mechanism is arranged above each water distribution pipe. The water distribution pipe near the main pipe is used for basic irrigation, and the water distribution pipe away from the main pipe is used for extension irrigation. A part of the water in the main pipe is sprayed out through the long pipe body, the short pipe body, the water ring and the spray head, and another part of the water passes through the short pipe body and enters the upper long pipe body, and then is sprayed out through the upper short pipe body, the water ring and the spray head, achieving the effect of double-height spraying. Although the comparative document can achieve the effect of multi-layer spraying, it requires more consumables and cannot adjust the position. Moreover, if a higher height is required, the height of the water distribution pipe will be too high, affecting the stability.

[0004] In the patent document with the application number "202322705993X", a fruit orchard anti-freezing rotary spraying device is disclosed, which includes a bottom plate, the number of bottom plates is two, a sleeve is rotatably connected to the middle of the upper surface of the bottom plate, a lifting column is threadedly connected to the top end of the sleeve, and a toothed disc is fixedly connected to the outer surface of the sleeve. The fruit orchard anti-freezing rotary spraying device, through the setting of the sleeve, the lifting column, the toothed disc and the worm, when the growth of the fruit trees approaches the spraying device, the worm can be directly rotated forward by the handle, the meshing effect of the worm and the toothed disc is utilized, the sleeve has a rotating effect on the bottom plate, the worm is rotated to make the toothed disc drive the sleeve to rotate, the sliding effect of the lifting column and the reinforcing plate is utilized, the sleeve is rotated to make the lifting column receive the screw thread force, so that the lifting column is lifted out of the sleeve, the height of the spraying device is increased, the worm is reversely rotated to make the sleeve reverse to drive the lifting column to move downward, achieving the function of adjusting according to the height of the fruit trees. Although the spraying device in the comparative document can adjust the height and spacing of the spray head, its structure is too complex, consumes too many materials and has high cost.
