摘　　要：针对玉米穴播穴灌机水分传感器在工作过程中的土壤测量深度要求和零速要求,设计开发了一种水分传感器驱动机构,通过水分传感器驱动机构数学模型的建立,借助Solidworks motion运动分析模块和Matlab软件对水分传感器驱动机构进行了优化设计.分析结果表明,该机构可实现水分传感器周期性测量土壤水分含量的功能,为玉米穴播穴灌机水分传感器驱动机构结构及运动参数的设计提供了理论依据.According to the requirements for depth of soil measurements and zero-speed at work,a soil moisture sensor driving mechanism for corn irrigating hill-seeder was designed.Based on the establishment of the mathematical model of the soil moisture sensor driving mechanism,the mechanism parameters were optimized by the motion analysis module of Solidworks motion and MATLAB software.The results showed that the driving mechanism could complete periodic measurements of soil moisture content,and provide the theoretical basis for the design structure and motion parameters of soil moisture sensor drive mechanism for corn irrigating hill-seeder.
