The invention discloses a pesticide spraying plant protection unmanned aerial vehicle which comprises an unmanned aerial vehicle body, a supporting mechanism, supporting rods, a sliding rod, a base, adamping spring, an adjusting mechanism, a rotating rod, a movable groove, a first bevel gear, a second bevel gear, a lead screw and a sliding plate. Beneficial effects of the unmanned aerial vehicleare that the four supporting rods and the sliding rod are mounted so that pressure reduction and shock resistance of the unmanned aerial vehicle body during landing are facilitated; damage of an impact force to the unmanned aerial vehicle is prevented; the rotating rod is rotated so that the first bevel gear drives the second bevel gear to rotate; and meanwhile, the lead screw drives the sliding plate to slide in each supporting rod under the action of the second bevel gear so that the sliding plate extrudes or expands a damping spring, and an elastic force of the damping spring is changed, abuffering and damping capacity of the unmanned aerial vehicle carrying different weights during landing is favorably regulated and controlled, and landing safety of the unmanned aerial vehicle is effectively guaranteed by regulating the damping force of the sliding rod and the supporting rods.
本发明公开了一种农药喷洒植保无人机,包括无人机本体、支撑机构、支撑杆、滑杆、底座、减震弹簧、调节机构、转杆、活动槽、第一斜齿轮、第二斜齿轮、丝杆和滑板。本发明的有益效果是:通过四个支撑杆和滑杆的安装,有利于对无人机本体在降落时进行减压抗震,防止冲力对无人机造成损坏,通过转动转杆,从而使第一斜齿轮带动第二斜齿轮转动,同时丝杆在第二斜齿轮的作用下驱动滑板在支撑杆内部滑动,使滑板对减震弹簧的挤压或舒张,从而使减震弹簧的弹力发生变化,有利于使背负不同重量的无人机在降落时的缓冲减震能力进行调控,通过对滑杆和支撑杆的减震力调节,从而有效的保障了无人机的降落的安全性。
