The invention relates to the technical field of
agricultural machinery, and discloses an unmanned aerial vehicle
pesticide spraying device for cherry trees, the unmanned aerial vehicle
pesticide spraying device comprises a main
machine body, a rack arranged on the periphery of the main
machine body, a supporting seat fixed to the rack and a spraying mechanism arranged on the main
machine body, the spraying mechanism comprises a box body arranged on the main machine body, and a high-pressure pump is arranged in the box body; a spray head
assembly is arranged below each group of supporting seats, a follow-up mechanism is further arranged below each group of supporting seats, the follow-up mechanisms are used for detecting strong wind blown by the side edge of the unmanned aerial vehicle, and when the follow-up mechanisms detect the strong wind on the side edge, the spray head assemblies are controlled to rotate in the blowing direction of the strong wind, and the spraying direction of the spray head assemblies is adjusted; the follow-up mechanism is used for sensing strong wind and immediately adjusting the spray head
assembly to rotate towards the blowing direction of the strong wind, so that the deviation degree of a
pesticide spraying path is reduced to a certain extent because pesticide which is originally blown to be deflected by the strong wind on the side is close to the blowing direction of the strong wind, spraying deviation caused by the wind is reduced, and waste of the pesticide is reduced.
