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 o...
