Design and Experiment of Wind-driven Spraying Mist Machine for Greenhase
摘要
Abstract
In greenhouse plant protection operation,knapsack swing operation is often used,and there are problems such as excessive application and uneven application effect.The design of an intelligent air spray spraying machine,the main structure includes axial flow fan,nozzle group,ground rail car,mixing box,high pressure water pump and so on.The control system is centered around an STM32 microcontroller.A flow sensor monitors the output of the pressure water pump,a liquid level sensor tracks the remaining pesticide volume in the mixing tank,and an ultrasonic distance sensor detects obstacles along the travel path.Experiments were conducted to evaluate the operational performance of the mist duster under varying wind speeds and nozzle elevation angles.Results indicate that at a nozzle elevation angle of 45° and a wind speed of 14 m/s,the maximum spraying distance reached 8.8 m,effectively ensuring the coverage area.Through simplified simulations using ANSYS Fluent,an optimal angle of 30° between the vertical lines of the nozzle and the fan was selected.This mist duster can autonomously adjust operational parameters according to the target,enabling targeted pesticide application and meeting the requirements of greenhouse spraying operations.关键词
