The invention belongs to the technical field of agricultural unmanned aerial vehicles, particularly relates to an agricultural plant protection unmanned aerial vehicle capable of conveniently controlling the flight attitude, and aims at solving the problems that the flight attitude control is unstable and the flight attitude is influenced by the vibration of a pesticide pot body. The following scheme is provided: the agricultural plant protection unmanned aerial vehicle comprises a vehicle body, six electric hydraulic rod bodies are annularly connected with the outer wall of the vehicle body at equal intervals, undercarriages are symmetrically arranged on the outer wall of the bottom end of the vehicle body, and a fixing disc is arranged in the middle of the outer wall of the bottom end of the vehicle body; and wing assemblies are arranged on the outer walls of the end parts of the electric hydraulic rod bodies. Wing arms are changed into telescopic rod bodies, the flight attitude of the vehicle body can be corrected and supplemented by changing the length of a force arm, a damping part is added into the pesticide pot structure and can reduce the vibration amplitude of pesticide liquid in the pesticide pot structure through a partition plate type structure when the flight attitude is changed, and the flight attitude is stable and controlled accurately through combination of the damping part and the pesticide pot structure.

    本发明属于农用无人机技术领域,尤其是一种便于控制飞行姿态的农业植保无人机,针对存在的飞行姿态控制不稳定和农药壶体的震动影响飞行姿态问题,现提出以下方案,包括机体,所述机体的外壁等距离环形连接有六个电动液压杆体,所述机体的底端外壁对称设有起落架,所述机体的底端外壁中部设有固定盘;机翼组件,所述机翼组件设于所述电动液压杆体的端部外壁上。本发明变更机翼臂为可伸缩杆体,可通过改变力臂长度,对机体的飞行姿态进行矫正和补充,在药壶结构中加入了减震件,减震件通过隔板式结构可减少内部农药液体在飞行姿态改变时的振动幅度,两者结合使飞行姿态稳定、控制精准。
