The invention relates to the technical field of general aerial equipment and discloses an aerial farming spray-irrigation unmanned aerial vehicle. The aerial farming spray-irrigation unmanned aerial vehicle comprises a base. A mounting frame is fixedly mounted at the top of the base, grooves are formed in the two sides of the front face and the back face of the mounting frame correspondingly, andaccommodating grooves are formed in the positions, located on the inner walls of the grooves, of the mounting frame; movable shafts located inside the accommodating grooves are arranged on the inner wall of the mounting frame, the middles of the movable shafts are fixedly sleeved with connecting sleeves, and a cantilever is welded to one side of each connecting sleeve; and fastening bolts are arranged on the inner wall, located in the grooves, of the mounting frame. According to the aerial farming spray-irrigation unmanned aerial vehicle, by forming the accommodating grooves, the cantilevers are stored into the mounting frame conveniently in the non-working state of the unmanned aerial vehicle, thus the situation that after long-time storing, dust and moisture enter the unmanned aerial vehicle, and then the operation sensitivity of the unmanned aerial vehicle is affected is avoided, the storing safety of the unmanned aerial vehicle is improved, and meanwhile the storing space of the unmanned aerial vehicle is optimized.
