The invention discloses a pesticide spraying unmanned aerial vehicle capable of conveniently adjusting the height of spraying rods. The pesticide spraying unmanned aerial vehicle is provided with a swing beam, the spraying rods, a linkage gear and a guide telescopic assembly, so that a driving assembly drives a linkage assembly to drive a rotating disc to rotate, and drives the swing beam to rotate so as to drive the spraying rod to move; when a rotary drum on the guide telescopic assembly rotates forwards to drive an ejector rod and a lock rod to perform contraction motion, a lock disc is attached to a hinge assembly under the acting force of a first spring so as to limit the rotational freedom degree of a disc and a hinge disc, and the lock rod contracts to be separated from a lock hole so as to release the vertical linear motion freedom degree of the hinge assembly; and at the moment, the driving assembly drives the linkage gear to drive the swing beam to perform vertical lifting motion on the spray rods, so that the first spray rod and the second spray rod are subjected to height adjustment in the vertical direction, the pesticide spraying height of the spray rods in the horizontal direction is adjusted, the risk of low flight of the unmanned aerial vehicle is effectively reduced, and waste of pesticide powder is reduced.

    本发明公开了一种便于调节喷杆高度的喷药无人机,通过设置摆梁、喷杆、联动齿轮以及导向伸缩组件,以使驱动组件驱动联动组件带动转盘转动的同时,驱动摆梁转动以带动喷杆进行运动;当导向伸缩组件上的转筒正转驱动顶杆和锁杆进行收缩运动时,锁盘在第一弹簧的作用力下贴合铰接组件,以限制圆盘和铰接盘的转动自由度,锁杆收缩脱离锁孔以放开铰接组件的竖直直线运动自由度;此时,驱动组件驱动联动齿轮带动摆梁可对喷杆进行竖直升降运动,使第一喷杆和第二喷杆在竖直方向上进行高度调节,从而调节喷杆水平方向的喷药高度,有效降低无人机低飞的风险和减少药粉的浪费。
