The invention relates to the technical field of low-altitude seeding, and discloses an auxiliary device for automatically controlling pesticide spraying and preventing pesticide liquid from flying away for a pesticide spraying unmanned aerial vehicle, the auxiliary device comprises a pressure applying mechanism and a flow guiding mechanism, the pressure applying mechanism internally comprises a sawtooth rod, one end of the sawtooth rod is fixedly connected with a sliding block, and the surface of the sawtooth rod is movably connected with a limiting block; the other end of the limiting block is fixedly connected with a fixing frame, the other end of the sawtooth rod is fixedly connected with a pressing plate, the top end of the pressing plate is movably connected with a sliding rail, when the push plate moves towards the inner side, the blocking column pushes the sawtooth rod to move towards the inner side to drive the pressing plate to extrude the medicine bag, and when the push plate moves towards the outer side, the limiting block limits the sawtooth rod; a sawtooth rod is prevented from being pulled outwards by a push plate, a pressing plate gradually moves inwards to extrude a medicine bag to spray medicine, a fan rotates to generate downward airflow, the downward airflow flows downwards along the arc-shaped outer wall of an arc-shaped plate, and spraying of the medicine liquid is guided while the flowing speed of the medicine liquid flowing out of the bottom of the medicine bag is increased.

    本发明涉及低空播种技术领域,且公开了一种喷药无人机用自动控制喷药防止药液飞散的辅助装置,包括施压机构、导流机构,所述施压机构的内部包括锯齿杆,锯齿杆的一端固定连接有滑块,锯齿杆的表面活动连接有限位块,限位块的另一端固定连接有固定架,锯齿杆的另一端固定连接有压板,压板的顶端活动连接有滑轨,当推板向内侧移动时,挡柱推动锯齿杆向内侧移动,带动压板挤压药囊,当推板向外侧移动时,限位块对锯齿杆限位,防止锯齿杆被推板向外侧拉动,使得压板逐渐向内侧移动挤压药囊,进行喷药,风扇转动产生向下的气流,沿着弧形板弧形外壁向下流动,加快药囊底部流出药液的流动速度的同时,对药液的喷洒进行导向。
