Agricultural plant protection unmanned aerial vehicle carrying mechanism

Abstract

The invention relates to an agricultural plant protection unmanned aerial vehicle carrying mechanism which comprises an integrated framework, an inner baffle, an outer baffle, undercarriage fixing boards, an undercarriage and a flight control sealing box. The integrated framework comprises an upper carbon fiber board and a lower carbon fiber board, pesticide box holes are formed in the upper carbon fiber board and the lower carbon fiber board of the framework respectively, two hole arms of the pesticide box holes are connected through the inner baffle, outer edges of the upper carbon fiber board and the lower carbon fiber board are connected through the outer baffle, four groups of undercarriage fixing boards are arranged on the lower carbon fiber board and fixedly connected with the undercarriage, and the flight control sealing box is placed outside the integrated framework. The mechanism is quite simple to disassemble, assemble and replace, maintenance difficulty and cost are greatly reduced, small mass of an unmanned aerial vehicle is ensured, and natural environment resistance is high.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a carrying mechanism of an agricultural and plant protection unmanned aerial vehicle. Background technique [0002] Plant protection UAV, as the name implies, is an unmanned aircraft used for agricultural and forestry plant protection operations. This type of unmanned aircraft consists of three parts: a flying platform (fixed wing, single rotor, multi-rotor), GPS flight control, and spraying mechanism. Remote control or GPS flight control to realize the spraying operation, which can spray chemicals, seeds, powder, etc. [0003] According to the book "China's Civil UAV Market Analysis and Prospect Forecast (2016 Trial Release)" published by Yuchen.com in 2016, my country's agricultural plant protection drones are still in their infancy. According to statistics, in 2014 my country's plant protection had no The number of man-machines is 695, with a total operating a...

Problems solved by technology

[0004] In addition to the control system and power system in the plant protection drone, the bearing mechanism that carries these two parts is also a very important part of the plant protection drone, and the current In order to ensure the various performances of the drone, the sealing mechanism of the plant protection drone generally has a complex structure and is difficult to disassemble. The adding process of the pesticide box carried by the carrying mechanism is complicated, the contact between the buffer pot and the pesticide box is not tight, and the valve of the pesticide box needs to be closed manually when not in use to ensure that the pesticide will not leak
