The invention discloses a plant protection unmanned aerial vehicle spraying anti-drifting device which is provided with an unmanned aerial vehicle body, a spraying pipe fitting, a pesticide supply and transportation structure, a storage driving mechanism and a telescopic positioning mechanism, and the storage driving mechanism is used for driving to rotate and ascend and descend so as to drive the spraying pipe fitting to be wound and stored on the storage driving mechanism; and the telescopic positioning mechanism is used for performing telescopic action along with lifting of the spraying pipe fitting and limiting the lifting direction of the spraying pipe fitting. According to the agricultural unmanned aerial vehicle, the spraying pipe fitting is stored when not spraying, and when the spraying pipe fitting sprays, the end of the spraying pipe fitting is driven to be released, so that the spraying pipe fitting is lowered to the position above a crop canopy by a certain height, the safety of the agricultural unmanned aerial vehicle during operation is improved, and it is guaranteed that pesticide liquid droplets are effectively deposited on the crop canopy; the utilization rate of the liquid medicine is improved; in addition, the lifting direction of the spraying pipe fitting is limited, and the influence of an external wind field and a rotor wing wind field on sprayed fog drops is reduced to the maximum extent.

    本发明公开了一种植保无人机的喷雾防飘移装置,具备无人机机体、喷雾管件、供药运输结构、收纳驱动机构和伸缩定位机构,收纳驱动机构用于驱动做旋转动作和升降动作,以带动喷雾管件缠绕收纳于收纳驱动机构上,伸缩定位机构用于跟随喷雾管件的升降进行伸缩动作,并对喷雾管件的升降方向进行限位。本发明在喷雾管件未进行喷雾时将其收纳,在喷雾管件进行喷雾时,驱动将喷雾管件端部放出,使得喷雾管件降低一定高度位置至农作物冠层上方,提高农用无人机作业时的安全性,保证药液雾滴有效地沉积在农作物的冠层,提高了药液的利用率;另外,对喷雾管件的升降方向进行限位,最大程度减小了外界风场和旋翼风场对喷施雾滴的影响。
