履带式自动化微喷带铺设回收装置设计OA

[Objective]This study aims to design an automated,small-scale crawler-type micro-sprinkler tape laying and retrieval device to address the current issues of low automation levels and high labor input associated with existing micro-sprinkler tape laying and retrieval equipment.[Method]By conducting an in-depth analysis of practical operational requirements,a small-scale crawler-type mobile chassis and a micro-sprinkler tape laying and retrieval mechanism were designed.Basic parameters,including ground contact pressure,track pitch,and the required power for travel and reeling,were determined.Prototypes of the load-bearing wheel system,guide wheel system,and reeling roller system were fabricated using 3D printing technology with acrylonitrile-butadiene-styrene(ABS)copolymer as the raw material.ANSYS software was employed,in conjunction with actual operational conditions,to verify the strength of the designed components.Additionally,the motion process during micro-sprinkler tape retrieval was analyzed using SolidWorks Motion.A control system integrating remote control,autonomous navigation,and real-time monitoring functions was developed using an STM32 microcontroller combined with remote control modules,ultrasonic modules,and navi-gation modules.[Result]The strength of the components met the design requirements,and the proto-type exhibited good structural integrity.It demonstrated excellent traversability over soft farmland,ridges,and gentle slopes.The maximum actual travel speed achieved was 5.334 km·h-1,with an ave-rage deviation rate of 2.984%over a 50 m distance on firm ground.The micro-sprinkler tape laying and retrieval process proceeded smoothly,and all components of the control system operated stably,with a maximum navigation error of 1.87 m.[Conclusion]The equipment integrates remote control,autono-mous navigation,and real-time monitoring functions into one unit,meeting the needs for automated laying and retrieval of micro-sprinkler tape in farmland environments.
