WIPO Patent Application WO/2022/000922

A1

A frame (10) of a multi-rotor unmanned aerial vehicle, and an agricultural plant protection unmanned aerial vehicle (1) and a control method therefor. The frame (10) of a multi-rotor unmanned aerial vehicle comprises a central body (11), a plurality of arms (12), a plurality of rotor power devices (13), a plurality of nozzle assemblies (14) and an angle adjusting mechanism (15). The plurality of rotor power devices (13) are used to provide flight power for a multi-rotor unmanned aerial vehicle. The plurality of nozzle assemblies (14) are respectively mounted below the plurality of arms (12) and are respectively positioned below the rotor power devices (13). The angle adjusting mechanism (15) can adjust an included angle between the spraying direction of at least one nozzle assembly (14) of the plurality of nozzle assemblies (14) and a plane where the central body (11) is located. The frame (10) of a multi-rotor unmanned aerial vehicle, and the agricultural plant protection unmanned aerial vehicle (1) and the control method therefor can improve the uniformity of tree pesticide spraying.
