Aiming at the practical situation that the building standards of the current vineyard are not uniform and the planting row spacing is not uniform, the existing orchard pesticide applying machine has the problems that the orchard is difficult to enter, the canopy cannot be effectively matched and the like. The air-assisted sprayer with small size and structure and adjustable space structure of a pesticide application system is needed.
