The invention belongs to the technical field of unmanned aerial vehicles, and particularly relates to an agricultural unmanned aerial vehicle which comprises an unmanned aerial vehicle body, blowing wings are connected to the two sides of the unmanned aerial vehicle body through automatic rotators, outer flow channels are symmetrically formed in the tops of the blowing wings, the blowing wings are fixedly installed in the outer flow channels, inner flow channels are formed in the front sides of the outer flow channels, and cross flow fans are rotatably installed in the inner flow channels; and the four rotating machines are fixedly mounted at the bottoms of the two blowing wings correspondingly, and through the arranged cross flow fan and the blowing wings, it is ensured that in the flying process of the unmanned aerial vehicle, the cross flow fan rotates to suck air in front of the blowing wings of the unmanned aerial vehicle into inner flow channels of the blowing wings, and the air in front of the blowing wings of the unmanned aerial vehicle is blown into the blowing wings. The outer flow channel is arranged on the blowing wing, so that sucked high-speed airflow flows upwards on the blowing wing while passing through the outer flow channel, air pressure difference can be generated on the upper wing surface and the lower wing surface of the blowing wing, the unmanned aerial vehicle is lifted, larger lift force is obtained, enough lift force does not need to be obtained by increasing the size and the rotating speed of a propeller in order to deal with larger load, and crops cannot be damaged.
本发明属于无人机技术领域,尤其涉及一种农用无人机,包括:无人机身,无人机身的两侧均通过自动旋转器连接有吹翼,吹翼的顶部对称开设有外流道,外流道内固定安装有吹翼,外流道的前侧开设有内流道,内流道内转动安装有横流风机;四个转动机,四个转动机分别固定安装在两个吹翼的底部,通过设置的横流风机和吹翼,确保无人机在飞行的过程中,横流风机通过转动将无人机吹翼前方的空气吸入吹翼的内流道中,从而将吸入的高速气流在经过外流道的同时在吹翼上流过后,使吹翼的上下翼面能产生气压压差,将无人机托举,获得更大的升力,从而不用为了应付较大载荷来增加螺旋桨尺寸和转速来获得足够的升力,不会损害农作物。
