The invention provides an electromagnetic valve for a plant protection unmanned aerial vehicle, a spraying system and an air exhaust method. The electromagnetic valve comprises a valve element assembly, an adjusting assembly and an electromagnetic assembly. The adjusting assembly is arranged between the valve element assembly and the electromagnetic assembly. The adjusting assembly comprises a fixing shell, a driving gear, a rotating wheel, a connecting shaft and a first spring. The driving gear and the rotating wheel are arranged inside the fixing shell, the two ends of the rotating wheel abut against the driving gear and the valve element assembly correspondingly, and the two ends of the driving gear abut against the rotating wheel and the electromagnetic assembly correspondingly. One end of the connecting shaft abuts against the rotating wheel, and the other end of the connecting shaft abuts against the driving gear. The first spring sleeves the driving gear. The electromagnetic assembly is powered on and off, the adjusting assembly can be pushed to move so as to drive the valve element assembly to move, and therefore the electromagnetic valve can be located in an open or closedstate. The electromagnetic valve is low in power consumption and can be applied to the plant protection unmanned aerial vehicle spraying system, and the spraying operation efficiency is improved.

    本申请提供一种用于植保无人机的电磁阀、喷洒系统及排气方法,所述电磁阀包括:阀芯组件,调节组件和电磁组件,所述调节组件设置在所述阀芯组件和所述电磁组件之间;其中,调节组件包括:固定壳、驱动齿轮、转动轮,连接轴和第一弹簧;驱动齿轮与转动轮设置在固定壳内部,转动轮的两端分别与驱动齿轮和阀芯组件抵接,驱动齿轮的两端分别与转动轮和电磁组件抵接;连接轴的一端与转动轮抵接,连接轴的另一端与驱动齿轮抵接;第一弹簧套设在驱动齿轮上。通过对电磁组件进行通断电,可以推动调节组件运动,以带动阀芯组件运动,使电磁阀处于开启或闭合的状态。本申请提供的电磁阀耗电量小,可以应用于植保无人机喷洒系统中,提高喷洒作业效率。
