Plant protection unmanned aerial vehicle for agricultural planting

Abstract

The invention relates to the technical field of pesticide spraying equipment and discloses a plant protection unmanned aerial vehicle for agricultural planting, which comprises an unmanned aerial vehicle frame, wherein a spraying pesticide box is movably connected into the unmanned aerial vehicle frame in a clamped mode, a buoyancy pressing block is movably connected into the spraying pesticide box in a sleeved mode, and an elastic air bag is arranged at the top of an inner cavity of the spraying pesticide box and located above the buoyancy pressing block. In the plant protection unmanned aerial vehicle for agricultural planting, a buoyancy pressing block and an elastic air bag are arranged; the elastic air bag is used for forming pressure on the liquid level of the pesticide; when the unmanned aerial vehicle changes the flight state, the fluctuation generated during oscillation can be guided to enter the liquid pesticide again; according to the plant protection unmanned aerial vehicle, the impact on the spraying pesticide box is reduced; meanwhile, impact shaking generated by the spraying pesticide box can be effectively converted into internal energy of the disc spring, vibrationimpact on the unmanned aerial vehicle cannot be caused, and therefore, the balance and stability of the plant protection unmanned aerial vehicle in the flying state changing process are effectively improved.

Description

technical field [0001] The invention relates to the technical field of pesticide spraying equipment, in particular to a plant protection drone for agricultural planting. Background technique [0002] With the advancement of science and technology for the development of agricultural planting technology, the traditional farming planting mode has been gradually replaced by mechanized planting methods, and the large-scale mechanized agricultural planting mode has become an inevitable development trend. Among them, in order to ensure the normal output of crops in At different stages of its growth, it needs to be sprayed with pesticides to prevent pests and diseases and weeding operations. [0003] Among them, large-scale chemical spraying of crops with drones is the most efficient spraying method available, and its spraying efficiency and uniformity are beyond the reach of other spraying methods, but the existing drones When spraying crops with a medicine box, the UAV will often...

Problems solved by technology

[0005] The invention provides a plant protection unmanned aerial vehicle for agricultural planting, which has the advantage of being able to effectively prevent the unbalance of the unmanned aerial vehicle body caused by the vibration of the medicine box, and solves the problem that the existing unmanned aerial vehicle carries the medicine box to the crops. When spraying medicine, the UAV often changes its own flying state due to the terrain during the flight process, and at the same time, because the pesticide carried in the medicine box is in a liquid state, the UAV changes its own flight state. Due to the inertia, the pesticide in the medicine box will vibrate violently, which will impact the inside of the drone and affect the balance of the fuselage, resulting in poor stability of the drone during flight.
