Spraying mist droplet collecting device for agricultural unmanned aerial vehicle and use method thereof

Abstract

The invention discloses a spraying mist droplet collecting device for an agricultural unmanned aerial vehicle and a use method thereof. The spraying mist droplet collecting device comprises a foundation frame, a fixed base, a rotary rod, a collecting card placing assembly and a motor, wherein the fixed base is located on the foundation frame; the rotary rod is transversely arranged on the fixed base; the collecting card placing assembly is fixedly arranged on the rotary rod and is used for placing a collecting card; the motor is used for driving the rotary rod to rotate; the collecting card placing assembly comprises a rotary disc body, a plurality of collecting card placing grooves, moisture-proof separating doors and a moisture-proof separating door driving mechanism, the collecting cardplacing grooves are arranged at the surface of the rotary disc body along the circumference, each moisture-proof separating door corresponds to each collecting card placing groove and is used for separating the corresponding collecting card and the outside, and the moisture-proof separating door driving mechanism is used for driving the moisture-proof separating doors to be opened or closed. Thespraying mist droplet collecting device has the advantage that after the field operator places the collecting card at one time, the multiple times of sampling tasks can be continuously completed, so that the sampling efficiency is greatly improved, and the labor intensity of the field operator is greatly decreased.

Description

technical field [0001] The invention relates to a plant protection unmanned aerial vehicle, in particular to a spray drop collection device suitable for agricultural unmanned aerial vehicles and a method for using the same. Background technique [0002] my country is a large agricultural country, and the amount of pesticide application is huge, but the effective utilization rate of pesticides is low, which poses a huge threat to the environment and food safety. In recent years, precision agricultural aviation spraying technology with drones as the main carrier has gradually developed, which has greatly improved the efficiency of agricultural operations. However, due to the late start of agricultural aviation in my country, the relevant technologies are not very mature, and there are still some problems. However, there are still many technical difficulties to be overcome in the application of unmanned aerial vehicles to agriculture. [0003] Taking the spraying of droplets by...

AI Technical Summary

Problems solved by technology

The collection and testing device is relatively simple, just fix the droplet collection card on a single bracket through a double-headed universal clip, and then place it under the aircraft flight path. A test often requires multiple brackets to be arranged, which has high requirements for the layout personnel.

Especially in the paddy fields in the south, the movement of personnel is limited, and the layout efficiency is very low. Also, because the droplet collection cards are mostly made of hydrophilic materials, early deployment or late recovery may cause the droplet collection cards to be damp and deteriorate, affecting the test results. , after each test, the droplet collection card needs to be taken back in time, resulting in time-consuming and laborious, slowing down the progress of the test

At the same time, field experiments often require repeated comparisons, requiring relatively consistent environmental and meteorological conditions. If the time to collect and replace the droplet collection card is too long, changes in the meteorological conditions of the UAV operation will also affect the test results.
