The invention discloses a steering engine swing mechanism, an unmanned aerial vehicle and a spraying operation method thereof.The steering engine swing mechanism comprises a swing arm, a steering engine and a limiting abutting structure, the steering engine comprises a steering engine motor, a speed reducing mechanism and a steering engine output shaft which are in transmission connection in sequence, and the steering engine output shaft drives the swing arm to swing; the limiting abutting structure is used for limiting, abutting and fixing the steering engine output shaft and/or the swing armat the position of the swing end point of the swing arm. According to the steering engine swing mechanism, the swing arm can be limited and fixed at the position of the swing end point, so that the vibration problem of a transmission terminal caused by steering engine vacancy is eliminated, the vibration of the free end of the swing arm is reduced or eliminated, and the stability of the swing mechanism is improved. When applied to an unmanned aerial vehicle, the nozzle can achieve orientation adjustment and stable spraying operation, and the product performance and the operation effect of theunmanned aerial vehicle are improved.
本发明公开了一种舵机摆动机构、无人机及其喷洒作业方法,舵机摆动机构包括摆臂、舵机和限位抵靠结构,舵机包括依次传动连接的舵机电机、减速机构和舵机输出轴,舵机输出轴驱动摆臂摆动;限位抵靠结构用于在摆臂的摆动端点位置限位抵靠并固定舵机输出轴和/或摆臂。本发明的舵机摆动机构能够在摆动端点位置限位固定摆臂,从而消除舵机虚位带来的传动终端的振动问题,减少或消除摆臂自由端的振动,提升摆动机构的稳定性。应用在无人机中,可实现喷头的方位调节及稳定喷洒作业,改善无人机的产品性能和作业效果。
