AI Technical Summary

Technical Problem

During long-term drone flights, pesticides are prone to settling and stratification, affecting the uniformity and efficiency of pesticide application and leading to a decline in the effectiveness of crop pest and disease control.

Method used

A drone-based crop pest and disease control device was designed, employing a mixing system with two-stage and one-stage stirring blades rotating in opposite directions to create convection circulation and turbulent eddies. This breaks up the aggregation of pesticide molecules, keeps the pesticide in suspension, and achieves uniform spraying by combining an adjustable flow pump and nozzles.

Benefits of technology

It effectively avoids pesticide sedimentation and stratification, ensures uniform spraying of pesticides, improves the quality and efficiency of crop pest and disease control, and meets the needs of long-term drone operation.

Abstract

This invention discloses a drone-based crop pest and disease control device, relating to the field of crop irrigation equipment technology. It includes an agricultural drone, a patrol camera mounted on the drone, and a detachable pesticide tank. A guide sleeve is embedded below the agricultural drone, and multiple support blocks are equidistantly distributed along a circumferential trajectory below the guide sleeve. Multiple limiting grooves are equidistantly distributed along a circumferential trajectory at the bottom of the pesticide tank. Below the guide sleeve are secondary and primary stirring blades that can rotate in opposite directions. This invention, through the counter-rotation of the secondary and primary stirring blades, creates a convection circulation within the pesticide tank, forming a rolling vortex and reducing dead zones in the mixing. Simultaneously, it increases shear force, breaking up pesticide molecule aggregation, allowing the active ingredients in the pesticide to fully mix with water, avoiding excessively high or low local concentrations, and ensuring that every drop of pesticide sprayed onto the crop has a consistent concentration.
