The invention belongs to the technical field of 
plant protection unmanned aerial vehicles, and particularly relates to an agricultural planting 
plant protection unmanned aerial vehicle convenient for 
pesticide spraying, the agricultural planting 
plant protection unmanned aerial vehicle comprises an unmanned aerial vehicle main body and a storage end, the storage end is fixedly mounted on the outer wall of the bottom of the unmanned aerial vehicle main body, and driving mechanisms are mounted at the top end and two sides of the unmanned aerial vehicle main body; and an air collision mechanism is installed at one end of the 
material storage end and comprises an air collision 
barrel fixedly installed on the outer wall of one side of the 
material storage end, and the side, opposite to the 
material storage end, of the air collision 
barrel is rotationally connected with a shaft column. According to the unmanned aerial vehicle disclosed by the invention, through the arranged air collision mechanism, air flow can be generated in an air collision 
barrel in cooperation with an air hole I and an air hole II in the flying process of the unmanned aerial vehicle, so that when collision blades collide with the air flow, the collision blades and a shaft column can be driven to quickly rotate, and then a 
pesticide mixing mechanism is driven to operate through a transmission mechanism to mix 
pesticide liquid; the uniformity of the liquid 
medicine is ensured; and through the arrangement of the convex edges and the arc-shaped strip grooves, the wind collision effect of the collision fan blades can be improved.
