1、摘 要事实上,目前国内研制的部分移栽机在性能方面与国外目前广泛采用的移栽机的性能几乎机同,但是,国外的移栽机与育苗技术已成为一体,密不可分,因此应用广泛。移栽机的研究开发应当仍以半自动为主,半自动移栽机尽管栽植速度不快,还需要一定的辅助工,但是它结构简单、价格低、适应性好、使用方便,适合我国国情。移栽机研究开发不应当单纯追求自动化和高速度。国内移栽机械目前研究开发的重点,仍应放在半自动机型方面,形成标准化、系列化和规格化,以满足农业生产的不同需要。许多作物的移栽要求比较特殊,需要开发专用移栽机,国内在这方面存在空白。根据作物钵苗移栽的农艺要求,在分析了国内外众多移栽机的基础上优化设计了适合棉花
2、营养钵育苗移栽的的关键部件,并通过作业效果调查,分析研究了机械栽苗的一般规律,找出了影响栽苗效果的若干因素,确立了主要的工作部件的参数选择,从而我设计出了这台棉花幼苗移栽机。它具有很强通用性,可以实现一机多用,机的利用率提高移栽。降低移栽机成价格,充分发挥现代大工业的特点,性能优异,能够进行批量生产,降低移栽机成本。关键词:移栽机,农业,半自动,钵苗,棉花The Structure Design of Seedlings Transplanting MachineABSTRACTIn fact, there are currently part of the transplanting mac
