为实现打穴式移栽机高效成型满足农艺要求栽植孔,基于打孔移栽作业的工作特点,融合油菜移栽农艺要求,设计了一种纯滚动式油菜移栽栽植孔成型机.通过分析纯滚动机构运动机理,研究成孔机构的运动参数方程,建立成型栽植孔的参数方程.采用Matlab软件生成栽植孔理论轮廓线,并生成成型栽植孔的外形图,运用CATIA软件进行仿真分析得出成型栽植孔的轮廓曲线图,并将上述图形进行拟合模拟,验证了成孔机构结构参数与运动参数的合理性.试制样机,进行田间试验,试验结果表明:机具以慢2挡工作状态下前进速度为1.80～1.96 km/h,作业效率达到0.306 ～ 0.333 hm2/h,在黏土、壤土和砂土3种土壤中试验,其成孔的平均合...

In order to design a new rapeseed transplanting machine, a pure rolling-type transplanting hole-forming machine for rapeseed was developed in accordance with agricultural requirements for rapeseed transplanting and the features of transplanting hole formation. The motion mechanism of the pure rolling-type mechanism was analyzed to derive motion parametric equations for the hole-forming mechanism. Matlab was used to generate theoretical contour lines and outline drawings of the transplanting hole. CATIA was then used for simulation analysis to obtain the contour curve of the transplanting hole,...
