The invention belongs to the technical field of pesticide spraying of unmanned aerial vehicles, and particularly relates to a plant protection unmanned aerial vehicle which comprises a vehicle body, a rotating paddle is rotationally arranged at the top end of the vehicle body, a pesticide storage box is clamped to the lower portion of the vehicle body, a protection shell is fixedly connected to the lower surface of the pesticide storage box, and an adjusting assembly is arranged in the protection shell. The adjusting assembly comprises a first motor; the first gear is rotationally arranged on the bottom wall of the pesticide storage box, and the side, away from the bottom wall of the pesticide storage box, of the first gear is fixedly connected with a first motor; gear teeth of the first gear are meshed with an adjusting gear, one side of the adjusting gear is meshed with an auxiliary gear, and the auxiliary gear is meshed with the other adjusting gear; a plurality of spraying holes are formed in the surface of each adjusting gear, the area of each spraying hole is gradually reduced, and by arranging the adjusting gears and other structures, the problems that the speed of an airplane is reduced due to headwind, the spraying holes are fixed and unified, the probability that pesticide drifts downwards is increased, and the spraying range and the coverage area are reduced are solved.
本发明属于无人机农药喷洒技术领域,具体的说是一种植保无人机,包括机体,所述机体的顶端转动设置有旋转桨,所述机体的下方卡接有储药箱,所述储药箱的下表面固接有保护壳,所述保护壳内设置有调节组件,所述调节组件包括第一电机;转动设置在储药箱底壁的第一齿轮,所述第一齿轮远离储药箱底壁的一侧与第一电机固接;所述第一齿轮的轮齿啮合有调节齿轮,所述调节齿轮的一侧啮合有辅助齿轮,所述辅助齿轮啮合有另一个调节齿轮;每个所述调节齿轮的表面开设有若干个喷孔,每个所述喷孔的面积逐渐减小,通过设置调节齿轮等结构,解决了因逆风使飞机速度减慢,而且喷孔固定统一,导致农药向下飘移的机会增加,从而减小了喷洒范围和覆盖面积的问题。
