The invention relates to the field of unmanned aerial vehicles, in particular to an agricultural plant protection unmanned aerial vehicle which comprises an unmanned aerial vehicle body, a charging box, a corrugated hose, a strip-shaped square pipe, a fan-shaped hole, a cylinder, a fixing pin seat, an air cylinder, a micro motor, a strip-shaped cover, a triangular belt, a belt wheel, a rotary vanescrew and a circular hole. According to the invention, the five belt pulleys in transmission connection through the triangular belt are driven to rotate through the running micro motor; the connectedrotary vane screws rotate to scatter the particle materials entering the strip-shaped square tube out of the fan-shaped holes in the end surface of the cylinder; therefore, the device has the function of throwing substances such as granular fertilizers and the like; the problem that it is inconvenient for farmers to throw granular chemical fertilizer and other substances in a special environmentis solved, the connected strip-shaped square pipes are pushed and pulled by starting the air cylinder to be in a contraction or extension state, the two strip-shaped square pipes can be folded and unfolded inwards or outwards oppositely, and the effect of changing the size of a throwing area is achieved.
本发明涉及无人机领域,具体的说是一种农用植保无人机,包括无人机机体、装料箱、波纹软管、条形方管、扇形孔、圆筒、固定销座、气缸、微型电机、条形盖、三角带、皮带轮、旋片螺杆和圆孔。本发明,通过运行的微型电机带动经三角带传动连接的五个皮带轮旋转,使得相连的旋片螺杆旋转将进入条形方管内的颗粒物料从圆筒端面处的扇形孔撒出,从而具有投撒颗粒状化肥等物质的功能,解决农户在特殊环境下投撒颗粒状化肥等物质不便的问题,通过启动气缸处于收缩或伸展状态对相连接的条形方管进行推拉,能够将两个条形方管对向向里或向外收展,达到改变投撒区域大小的效果。
