Unmanned aerial vehicle spraying process

Abstract

The invention discloses an unmanned aerial vehicle spraying process. An unmanned aerial vehicle body is included, a storage box used for containing a sunshade cooling agent is arranged at the bottom of the unmanned aerial vehicle body, a main material guiding pipe used for conveying the sunshade cooling agent is arranged on one side of the storage box, a plurality of branch material guiding pipes are arranged on one side of the main material guiding pipe, the unmanned aerial vehicle spraying technology comprises the steps that a rubber air bag is connected with a branch material guide pipe, a regulation and control unit for adjusting the spraying strength of a sunshade cooling agent is arranged in each branch material guiding pipe, the bottom end of each branch material guiding pipe is in threaded connection with an annular plate, and a limiting device for controlling the spraying range of the sunshade cooling agent is arranged at the bottom end of the annular plate. According to the unmanned aerial vehicle spraying process, a rubber airbag fits with the ring after inflation, a part of the ring is sealed, a channel through which the sunshade cooling agent passes through the branch material guiding pipe is narrowed, under the condition of the same output volume, due to the fact that the output channel is narrowed, the pressure when the sunshade cooling agent is output is increased, and the spraying distance of the sunshade cooling agent is increased.

Description

technical field [0001] The invention relates to a spraying process, in particular to an unmanned aerial vehicle spraying process. Background technique [0002] In agricultural planting, greenhouses are widely used, but under the sunlight in spring and summer, the sunlight in the greenhouse is strong and the temperature is too high, which will cause damage to the crops. The crops need shading and cooling. Now farmers use sunshading and cooling agents. spraying equipment. With the development of science and technology, traditional artificial agriculture is moving towards modern agriculture, and the traditional backpack operation method is gradually replaced by mechanical operation. The combination of drones and spraying technology can reduce labor and improve work efficiency. [0003] The existing UAVs have insufficient battery life in spraying sunshade and cooling agents, and need to replace the storage box many times, which reduces the work efficiency. Moreover, the existin...

Problems solved by technology

[0004] The purpose of the present invention is to provide a drone spraying process to solve the problem that the existing pesticide drones and plant protection drones in the above background technology have insufficient battery life in spraying sunshade cooling agents and cannot meet the load of sunshade cooling agents. It is inconvenient to install and disassemble the replacement of the sunshade and cooling agent, and the water output cannot meet the spraying requirements of the sunshade and cooling agent, which reduces work efficiency. Moreover, the spraying of the sunshade and cooling agent by the pesticide drone and the plant protection drone is uneven, and the spraying range is limited. The problem of limited utilization of sunshade and cooling agents
