,具体涉及一种植保无人机。
技术介绍
随着现代化农业的发展,将无人机用于植保作业可以大大减少人力作业,具有明显优势。但是相比于植保车与航化飞机,植保无人机的载药量较少,续航力不足。为了提高植保无人机的生产作业效率,目前多采取加大药液浓度的方式,以减少补充药液的次数,但相应的须提高无人机的飞行速度,以保持一定的农药施用量,从而控制成本与保证食品安全。随着药液浓度的提高,对植保无人机的喷施均匀性提出了更高的要求。多旋翼植保无人机由于操纵方便、成本较低,是目前植保无人机主要的形式,如公开号为CN106347648A的中国专利公布了一种多旋翼植保无人机,包括起落架、机身、机架、机臂、主旋翼、辅助旋翼、喷洒系统和控制系统,机身设置在起落架上方并与起落架连接,机架设置在机身上方并与机身连接,机臂安装在机架上,机臂为偶数个且对称分布在机架上,机架上部设置有发动机,主旋翼与发动机的输出轴连接,各机臂上均设置有电动机,各电动机的输出轴均与对应的辅助旋翼连接,各机臂上均设置有扰流板,扰流板用于抵消主旋翼旋转时产生的反扭矩作用,控制系统、发动 ...
