Agricultural pesticide spraying unmanned aerial vehicle for hilly areas and control method of agricultural pesticide spraying unmanned aerial vehicle

Abstract

The agricultural pesticide spraying unmanned aerial vehicle comprises a round fuselage, a propeller mechanism, a battery pack and a controller are installed at the top of the round fuselage, the bottom face of the round fuselage is connected with a mounting plate through four annularly-arranged first air cylinders, and four sets of air injection mechanisms are arranged on the side face of the round fuselage; the air injection mechanism and the first air cylinder are alternately arranged, the air injection mechanism comprises a horizontal air injection hole, an upward-inclined air injection hole and a downward-inclined air injection hole, an air pump and a compressed air storage tank are installed at the top of the mounting plate, a liquid storage tank is installed at the bottom of the mounting plate, an electric control sprayer is installed at the bottom of the liquid storage tank, and a second air cylinder is installed at the top of the mounting plate; the piston end of the second air cylinder penetrates through the mounting plate and then is connected with a sealing plug arranged in the liquid storage tank, and the piston end of the first air cylinder is connected with the circular machine body through a flexible connector. The defects in the prior art can be overcome, and the control precision of the pesticide spraying unmanned aerial vehicle on the pesticide spraying operation parameters is improved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an agricultural spraying unmanned aerial vehicle in hilly areas and a control method thereof. Background technique [0002] With the rapid development of drone technology, the use of drones to spray large areas of farmland has gradually become popular. In hilly areas, due to the complex terrain, if the drone wants to maintain a relatively stable spraying altitude and flying speed, it needs to make frequent adjustments to its fuselage. However, the spraying drone needs to carry a heavy drug storage tank, which leads to its large flight inertia and cannot quickly adjust the balance of the fuselage, which makes it impossible to achieve high-precision spraying operations in hilly areas. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide an agricultural spraying unmanned aerial vehicle in hilly areas and a co...
