The invention discloses a plant protection unmanned aerial vehicle multifunctional self-adaption variable and variable diameter spray head which comprises an unmanned aerial vehicle self-adaption spray head body, the unmanned aerial vehicle self-adaption spray head body is composed of four sets of spray bodies, valve bodies, electromagnetic valves, spray head bodies and nozzles, the spray bodies are symmetrically arranged, and the lower ends of the four sets of spray bodies are connected with the spray head bodies; the four sets of electromagnetic valves are evenly installed on the outer side of the spraying body, the four sets of valve bodies are arranged in the four sets of electromagnetic valves respectively, the four sets of electromagnetic valves are connected with an unmanned aerial vehicle master controller through control signal lines and conduct signal transmission through pulse signals, and a protection disc is arranged on the lower portion of the spraying body. The spraying body is embedded in the protection disc, and four sets of fixing positions are evenly formed in the bottom. According to the spraying system, the advantages and characteristics of large flow, good settling performance and uniform atomization of the pressure spraying head and high flow control precision and difficulty in blockage of the centrifugal spraying head are combined, the spraying effect of large flow and high settling performance can be realized, and the flow control precision and pipeline blockage can be improved.

    本发明公开了一种植保无人机多功能自适应变量变径喷头,包括无人机自适应喷头,无人机自适应喷头由喷体、阀体、电磁阀、喷头和喷嘴组成,喷体分设有四组且对称设置,四组喷体的下端与喷头相连接,电磁阀分设有四组且均匀安装于喷体的外侧,阀体分设有四组且分别内置四组电磁阀内,四组电磁阀通过控制信号线与无人机主控连接并通过脉冲信号进行信号传输,喷体的下部设置有防护盘,喷体内嵌于防护盘内且底部均匀开设有四组固定位。本发明将压力喷头大流量、较好的沉降性能以及雾化均匀与离心喷头流量控制精度高不易堵塞的优势和特点相结合,实现既可以大流量、高沉降性的喷洒效果,又可以在流量控制精度和管路堵塞上有所改进的一种喷洒系统。
