履带式油菜苗移栽栽植孔成型机的设计与试验

为设计新型油菜移栽机,基于旱地移栽作业的工作特点,融合油菜移栽农艺要求,研制了一种履带式油菜移栽栽植孔成型装置。通过分析土壤物理机械力学特性,求取打孔机构垂直出土所受摩擦阻力参数方程,为关键部件打孔机构的机构设计提供力学参数与理论依据;完成关键部件—打孔机构、靠模凸轮进行设计及优化后,设计并试制试验样机,进行田间试验。试验结果表明：机器以慢一档工作状态下前进速度为1.65∽1.78 km/h,作业效率达到0.231∽0.249 hm2/h,其成孔的平均合格率也达到93.8%。研制的机器能形成满足设计要求的栽植孔,为新型移栽机的设计提供技术支持。...

In order to resolve some key issues about the machinery of transplanter for rape seedlings, a new type of transplanter with crawler planting hole forming tools for rape was designed based on the working characteristic in the dry land and agronomic requirement. Research on soil physical and mechanical characteristics were conducted to provide the technical parameters for the design of the hole forming device. First, we completed the whole structure design and a
