The invention discloses a monitoring device for pesticide spraying of an agricultural plant protection unmanned aerial vehicle. The device comprises an unmanned aerial vehicle, a hinge seat is fixedlyconnected to the outer side of the unmanned aerial vehicle, a rotating rod is hinged to the lower end of the hinge seat, a limiting block is fixedly connected to the outer side of the rotating rod, aliquid medicine barrel is clamped to the left end of the limiting block, and a liquid medicine cover is connected to the upper end of the liquid medicine barrel through threads. According to the invention, the connecting rod is slidably connected with the liquid medicine cover; the connecting rod is fixedly connected with the floating ball; the connecting rod is fixedly connected with the connecting block; the floating ball can float on the surface of liquid medicine in the liquid medicine barrel; when the liquid level of the pesticide liquid is lowered, the floating ball can also descend along with the pesticide liquid, the floating ball can drive the connecting rod to descend, the connecting rod can drive the connecting block to descend, after the pesticide in the pesticide liquid barrel is sprayed, the connecting block can make contact with the alarm switch, the alarm switch can give an alarm prompt, and an operator is reminded to control the unmanned aerial vehicle to return and supplement the pesticide in time.

    本发明公开了一种农业植保无人机喷洒农药的监测装置,包括无人机,所述无人机的外侧固定连接有铰接座,所述铰接座的下端铰接有转动杆,所述转动杆的外侧固定连接有限位块,所述限位块的左端卡接有药液桶,所述药液桶的上端通过螺纹连接有药液盖。本发明通过设计连接杆和药液盖的滑动连接,连接杆和浮球的固定连接,连接杆和连接块的固定连接,浮球可以漂浮在药液桶内的药液表面,当药液的液位降低时,浮球也会随之降低,浮球会带动连接杆降低,连接杆会带动连接块的降低,当药液桶内的农药喷洒完后,连接块会与警报开关接触,警报开关会发出报警提示,提示操纵人员控制无人机及时返航补充农药。
