The invention relates to the technical field of agricultural unmanned aerial vehicles, and discloses a multi-rotor pesticide spraying unmanned aerial vehicle. The unmanned aerial vehicle comprises a body, supporting rods are fixedly installed on the four sides of the body, bends are fixedly installed on the sides, close to the body, of the supporting rods in a broken mode, and a first motor is fixedly installed on the upper surface of one end of each supporting rod. According to the multi-rotor pesticide spraying unmanned aerial vehicle, high-pressure spray heads which are movably installed are movably matched with a swing rod, and under the transmission cooperation of a first transmission gear, a second transmission gear, a first conical gear, a second conical gear and rotating teeth, when the high-pressure spray heads spray pesticide mist, upward counter-acting force is converted into shift of the swing rod, the shift is converted into the rotating force of the first transmission gear, and the rotating force is transmitted to the rotating teeth to drive the spray heads to rotate, so that the sprayed pesticide mist has the rotating force, the downward spraying range of the pesticide mist is wider, the pesticide mist inclines downwards, and the pesticide mist directly reaches the bottoms of crops more sufficiently under the combined action that the rotors generate airflow to blow the crops to incline.

    本发明涉及农业无人机技术领域,且公开了一种多旋翼打药无人机,包括机体,所述机体的四面固定安装有支撑杆,所述支撑杆靠近机体的一侧打断固定安装有弯转头,所述支撑杆一端的上表面固定安装有电机一。该多旋翼打药无人机,通过活动安装的高压喷头与摆杆活动配合,在传动齿一、传动齿二、锥齿一、锥齿二。转动齿的传动配合下,使得高压喷头在喷射药雾时,向上的反向作用力,转化成摆杆的位移,再转换成传动齿一的旋转力,传动到转动齿带动雾头旋转,使得喷出的药雾有旋转力,药雾旋转向下喷射范围更广,且方向为倾斜向下,在旋翼产生气流吹动农作物倾斜的共同作用下,药雾直接到达农作物底部更充分。
