The invention discloses a multi-rotor plant protection unmanned aerial vehicle with a self-adaptively adjusted spraying device. The multi-rotor plant protection unmanned aerial vehicle comprises an unmanned aerial vehicle body, vehicle arms, the spraying device, a pesticide box and a control unit. A device groove is formed in the unmanned aerial vehicle body and used for installing a pesticide box. A stirring device is designed in the pesticide box to ensure uniform mixing of pesticide liquid, and when the unmanned aerial vehicle is subjected to instability, inclination or rolling flight due to internal and external interference, shaking of the pesticide liquid in the pesticide box can be reduced, and the stability of the unmanned aerial vehicle is improved; the spraying device can utilize the control unit to carry out coordinated control on the spray head according to external environment changes and different operation parameters, so that the spraying direction of the spray head is always aligned with a target area, and the adverse effect of a rotor wing wind field of the unmanned aerial vehicle on the swing operation effect of the spray head is reduced through the follow-up paddle arranged on the spray rod in a sleeving mode. The spraying width, range and spraying angle of the unmanned aerial vehicle can be flexibly adjusted, the influence of shaking of pesticide liquid in the pesticide box on the stability of the unmanned aerial vehicle body is reduced, and the droplet spraying coverage rate and the precise pesticide applying effect of a spraying area are improved.

    本发明公开了一种喷雾装置自适应调整的多旋翼植保无人机,包括无人机机体,机臂,喷雾装置,药箱及控制单元;无人机机体内部开设有装置槽,用于安装药箱;药箱内部设计有搅拌装置,保证药液混合均匀,在无人机受内外部干扰发生失稳、倾斜或横滚飞行时,能减少药箱中药液晃动,提高无人机稳定性;喷雾装置可根据外界环境变化及不同作业参数,利用控制单元对喷头进行协调操纵,使喷头的喷洒方向始终对准目标区域,并通过套在喷杆上的随动桨叶,降低无人机旋翼风场对喷头摆动作业效果的不利影响。本发明能实现无人机喷幅大小、范围和喷洒角度灵活调整,并降低药箱内药液晃动对无人机机体稳定性的影响,提高喷洒区域的雾滴喷洒覆盖率及精准施药效果。
