摘要
分析了鸭嘴移栽机栽植机构的工作原理与过程,建立了七杆栽植机构的运动学模型。借助MATLAB软件对数学模型进行求解,对相关参数进行了优化计算,得到了主要参数的最佳组合,并模拟出栽植点的作业轨迹曲线,对栽植点运动轨迹特点进行了研究,从而直观地分析其作业性能。研究表明,所设计的七杆栽植机构具有良好的移栽性能,能满足移栽作业的农艺要求,为移栽机设计中栽植机构的运动参数和结构参数的确定提供了依据。
the working principle and process of the duckbilled-type planting mechanism is analyzed here, and a kine- matic mathematical model of seven-rod planting mechanism is established. At the aid of MATLB, the mathematical mod- el is calculated, and relevant parameters are optimized. By doing so, the most superior combination of the main parame- ters is extracted. The planting point work path curve is simulated. For planting point trajectory characteristics were stud- ied, and then we could analyze the performance of the transplanter intuitively. Research shows that the design of the sev- en-rod planting mechanism has a good performance and can meet the requirement of agricultural operation. It provides a basis for the determination of motion parameters and structures parameters of planting mechanism in design of transplan- ter.
