The invention relates to the technical field of unmanned aerial vehicles, and discloses a pesticide spraying unmanned aerial vehicle device capable of avoiding the situation that wings are clamped atbranches and cannot escape from the branches. The device comprises a base, the top of the base is fixedly connected with a storage bin, an extension rod penetrates through the side wall of the base, asupporting frame is fixedly installed at the outer end of the extension rod, the top of the supporting frame is movably connected with a through pipe, the upper end of the outer side wall of the through pipe is fixedly connected with a fixing block, and a groove is formed in the outer side of the fixing block. When the movable ring cannot rotate, the connecting rope can be pulled, the connectingrope can drive the fan blades to be erected; the fan blades can bypass the branches clamped at the transverse area, and resistance of getting out of difficulty of an unmanned aerial vehicle device isreduced; when the movable ring in the supporting frame cannot rotate, the unmanned aerial vehicle continuously lands, the movable ring continuously pulls the connecting rope downwards, the fan bladescan be pulled downwards by the connecting rope after being erected, the height of the fan blades is reduced downwards, the clamped area of the fan blades can be reduced, and the unmanned aerial vehicle can smoothly escape.
本发明涉及无人机技术领域,且公开了一种避免机翼被卡于树枝丫处无法脱困的喷药无人机装置,包括底座,所述底座的顶部固定连接又放置仓,底座的侧壁处贯穿有延伸杆,延伸杆的外端固定安装有支撑架,支撑架的顶部活动连接有通管,通管的外侧壁上端固定连接有固定块,固定块的外侧开设有槽。通过活动圈无法转动时,可拉动连接绳,连接绳可带动扇叶竖起,使扇叶能够绕开横向面积处卡住的树枝丫,减少无人机脱困的阻力,支撑架内部的活动圈无法转动时持续降落,活动圈继续向下拉动连接绳,在扇叶竖起之后能够再被连接绳向下拉动,将扇叶向下缩短高度,可减少扇叶被卡住的面积,使无人机能够顺利脱困。
