Suspension mist spray device applicable to fixed-wing unmanned aerial vehicles and method for applying suspension mist spray device

Abstract

The invention discloses a suspension mist spray device applicable to fixed-wing unmanned aerial vehicles and a method for applying the suspension mist spray device. The suspension mist spray device comprises a pesticide tank spray module and a suspension fixing module. The suspension fixing module is used for suspending the pesticide tank spray module on the lower sides of wings, and the pesticidetank spray module comprises a pesticide tank, a spray assembly and power batteries; the suspension fixing module comprises a wing clamping mechanism and a suspension release mechanism, the wing clamping mechanism is detachably mounted on the lower sides of the wings, the suspension release mechanism is arranged on the wing clamping mechanism, is used for quickly replacing the pesticide tank spraymodule and comprises an electromagnetic lock, electromagnetic lock shafts with horizontal expansion and contraction functions are arranged on the electromagnetic lock, and lock holes are formed in the pesticide tank and are matched with the electromagnetic lock shafts. The suspension mist spray device and the method have the advantages that pesticide liquid can be timely supplemented for the suspension mist spray device in pesticide tank spray module quick replacement modes, accordingly, the work efficiency can be improved, and damage on bodies of the unmanned aerial vehicles due to pesticidefeeding modes can be prevented.

Description

technical field [0001] The invention relates to the research field of plant protection equipment for unmanned aerial vehicles, in particular to a mounted spraying device suitable for fixed-wing unmanned aerial vehicles and a method for using the same. Background technique [0002] In order to ensure food production, a large amount of chemical fertilizers and pesticides are used around the world every year. my country is a large agricultural country. According to statistics, the current use of chemical fertilizers and pesticides in my country accounts for 30% of the world's total, but the effective use efficiency is far lower than that of developed agricultural countries. The purpose of precision agricultural aviation technology came into being. Countries around the world have a broad consensus on the development potential and application prospects of low-volume, high-efficiency and precision pesticide application technologies. It has gradually become the preferred method of...

The difference between the two is: for the rotor UAV, affected by factors such as its own weight, rotor layout and battery energy density, it has limited load capacity, short battery life, and poor spraying effect when performing field operations. It is not easy to control and other deficiencies; and unlike the rotary-wing UAV, the agricultural fixed-wing UAV has the advantages of large load and long battery life when performing field operations, and the airflow and wind field during spraying is stable, so that it can Auxiliary droplet deposition achieves a better spraying effect, but limited by the current traditional and complicated spraying system, the medicine box and the body of the drone are mostly designed in one piece. When the pesticide in the medicine box is used up, it needs to Add medicine to the medicine box through special equipment, the process lasts for a long time, and it is relatively easy to cause damage to the drone
