Plant protection unmanned aerial vehicle spray simulation and test device

Abstract

The invention discloses a plant protection unmanned aerial vehicle spray simulation and test device which comprises a test rail frame formed by two linear guide rail mechanisms. A traveling mechanismis arranged on the test rail frame, a lifting mechanism is hung on the bottom surface of the traveling mechanism, a swing mechanism is hung on the bottom surface of the lifting mechanism, a rotating mechanism is mounted on the bottom surface of the swing mechanism, an unmanned aerial vehicle is hung on the lower portion of the rotating mechanism, a spray mechanism is mounted on the unmanned aerialvehicle, a wind field simulation device for simulating outside real wind field environments is arranged on the test rail frame and comprises two side wind fans and a plurality of cross wind fans, water sensitivity paper for acquiring distributing conditions of sprayed pesticide droplet deposition amount is arranged on the ground in the test rail frame, and a test frame for measuring pesticide droplet spreading conditions is arranged outside the test rail frame. The device can reproduce various test conditions, each test can be controlled, test results can be repeated, and scientific sprayingbases are provided for pesticide spray in the real environments.

Description

technical field [0001] The invention relates to a test device for an unmanned aircraft for plant protection, in particular to a simulated spray test device for an unmanned aircraft for plant protection. Background technique [0002] As an advanced spraying tool, the plant protection unmanned aerial vehicle has the advantages of high efficiency, fastness and adaptability to different terrains. When an unmanned aircraft is spraying pesticides in flight, its flight speed, flight height, rotor pitch, inclination of the drone body (spraying system) and external wind speed will all affect the quality of pesticide application. In order to obtain the best pesticide application data at different altitudes, speeds, inclinations and wind speeds in current technology, unmanned aircraft need to conduct flight tests in various environments. However, in reality, due to the uncertainty of external test conditions, the test results are often not repeatable, so it is difficult to obtain the ...
