[0002] In fields such as agricultural and forestry plant protection and emergency disinfection, drone spraying technology has been widely used due to its advantages such as high operating efficiency and strong terrain adaptability. Among them, centrifugal atomizing spraying devices have become key components for improving spraying effect due to their fine droplets and uniform coverage.

[0003] In actual operations, due to differences in crop planting row spacing, plant height, and terrain, it is necessary to flexibly adjust the tilt angle of the spraying device to ensure that the pesticide can be evenly covered all parts of the crop. However, traditional pressure spraying devices usually adopt a fixed installation structure, and the spraying angle is difficult to adjust in real time according to actual needs. Even if some devices have angle adjustment functions, they are often complicated to operate and require manual shutdown for adjustment, which greatly reduces the efficiency of operation. Therefore, we propose a centrifugal atomizing drone omnidirectional spraying device. Utility Model Content
