The invention belongs to the field of unmanned aerial vehicle plant protection, and particularly relates to an unmanned aerial vehicle vertical descending sprayer which comprises a spraying device arranged at the lower end of an unmanned aerial vehicle in a suspended mode, the spraying device comprises a mandrel supported between unmanned aerial vehicle foot stools, supporting rod assemblies are arranged on the two sides of the mandrel, and a rotary rotating sleeve is arranged in the middle of the mandrel in a sleeving mode; the rotary rotating sleeve is arranged on the outer side of the mandrel in a sleeving mode and is in running fit with the mandrel, the rotary rotating sleeve is provided with an annular water collecting cavity communicated with the water inlet channel and a water outlet pipe communicated with the annular water collecting cavity, the water outlet pipe is connected with a liquid spraying pipe, and a bearing assembly and a sealing assembly are arranged between the rotary rotating sleeve and the mandrel. A water inlet pipe opening is formed in the side, away from the rotary rotating sleeve, of the water inlet channel and communicates with a liquid tank arranged on the unmanned aerial vehicle through a pesticide conveying pipe. The device is ingenious in structural design, the rotary rotating sleeve can rotate around the central spindle, and the flexible liquid spraying pipe shuttles back and forth between vegetation under the self counter weight; when the unmanned aerial vehicle finishes operation and needs to be stopped, the flexible liquid spraying pipe can slowly fall down.
本发明属于无人机植保领域,具体涉及一种无人机垂降喷头,包括垂吊设置在无人机下端的喷洒装置,喷洒装置包括支撑于无人机脚架之间的芯轴,芯轴两侧设置有支撑杆组件,芯轴中部套设有回转转动套,芯轴上设有进水通道,回转转动套套设在芯轴外侧并与芯轴转动配合,回转转动套具有与进水通道连通的环形集水腔和与环形集水腔连通的出水管,出水管连接有喷液管,回转转动套与芯轴之间设有轴承组件和密封组件,进水通道远离回转转动套一侧设置有进水管口,进水管口通过输药管与无人机上设置的液箱连通。本装置结构设计巧妙,回转转动套可绕芯轴旋转,柔性喷液管在自身配重下穿梭于植被间;在无人机作业完成需要停机时,柔性喷液管可缓慢落下。
