Pesticide hole adjusting mechanism of pesticide spraying unmanned aerial vehicle

The utility model relates to the technical field of unmanned aerial vehicles, and discloses a pesticide hole adjusting mechanism of a pesticide spraying unmanned aerial vehicle, which comprises an unmanned aerial vehicle body, and a spraying mechanism and a damping mechanism are arranged on the bottom surface of the unmanned aerial vehicle body. A pipe cover is rotated to put in pesticide liquid, an external power source starts a first motor, the first motor drives a first stirring rod to rotate, the entered pesticide liquid is stirred, the pesticide liquid can be better mixed, a first filter plate, a second filter plate and a third filter plate are arranged, and the pore sizes of the three filter plates are different, so that the pesticide liquid can be better mixed; by arranging a first stirring rod to drive a first baffle to move, the first baffle shields the surface of a third filter plate and the bottom face of a second filter plate, and therefore pesticide liquid can only flow out from the other side; t
