Title
(EN) Rack of multi-rotor unmanned aerial vehicle, agricultural plant protection unmanned aerial vehicle, and control method
(ZH) 多旋翼无人飞行器的机架、农业植保无人机及控制方法
Abstract
(EN) A rack of a multi-rotor unmanned aerial vehicle, an agricultural plant protection unmanned aerial vehicle and a control method are provided. The rack of a multi-rotor unmanned aerial vehicle comprises a center body (11), a plurality of arms (12), a plurality of rotor wing power devices (13), a plurality of nozzles (14) and a plurality of angle adjusting mechanisms (17). The rotor wing power devices (13) are mounted on the arms (12) and used for providing flight power to the multi-rotor unmanned aerial vehicle. The nozzles (14) are installed below the multiple arms (12) correspondingly and located below the rotor wing power devices (13) correspondingly. The angle adjusting mechanisms (17) are installed on the arms (12), are used for rotatably connecting the arms and the center body, and can adjust the included angle between each arm and the center body so that the spraying direction of each nozzle is a direction towards the lower inclined part of the center body. The agricultural plant protection unmanned aerial vehicle can ensure that more tree branches and leaves can be sprayed with farm chemicals and the uniformity of farm chemical spraying on trees by unmanned aerial vehicles can be improved.
(ZH) 一种多旋翼无人飞行器的机架、农业植保无人机及控制方法。多旋翼无人飞行器的机架包括中心体(11)、多个机臂(12)、多个旋翼动力装置(13)、多个喷嘴(14)及多个角度调节机构(17)。旋翼动力装置(13)设于机臂(12)上。多个旋翼动力装置用于提供飞行动力给多旋翼无人飞行器。多个喷嘴(14)分别安装在多个机臂(12)的下方,并且分别位于旋翼动力装置(13)的下方。多个角度调节机构(17)分别设于多个机臂(12)上,且用于将机臂与中心体可转动连接。角度调节机构(17)能够调节机臂与中心体之间的夹角,使喷嘴的喷洒角度朝向中心体的斜下方。该农业植保无人机可以保证较多的树枝及树叶能够喷洒到农药,提高农业植保无人机对树木喷洒农药的均匀度。
