文档介绍：新型组合清粮机的设计(动力传动部分)
摘要:
本文通过对当今国内外粮食清理机械的发展现状的研究,探讨了清粮机的现状和发展趋势,并针对现有清粮机的优缺点,通过对设计原理的详细研究,得出了最佳的新型组合清粮机设计方案。本人负责对组合清粮机的动力传动部分的主要参数进行详细的论证和各主要部件的选择计算,并根据提高粮食清理质量和减少环境污染因素的目的,为组合清粮机的设计提供了理论依据。本课题小组设计的新型组合清粮机,经试验检定,具有良好的环保性能,在成功处理大流量粮食的同时不会因为产生的粉尘而对环境造成污染和对操作工人的呼吸健康造成威胁,故此新型组合清粮机设计方案合理,具有良好的发展前景和市场潜力。

Abstract :
This article has discussed the grain cleaning machine present situation and the development tendency,, has discussed the grain cleaning machine present situation and the development tendency, and aims at the existing grain cleaning machines the good and bad points, through to the principle of design dissect, has obtained the best bination grain cleaning machine design proposal. Myself am responsible bine the grain cleaning machine the power drive partial main parameters to carry on the detailed proof and each ponent putation, and according to improves the grain cleaning up quality and the reduction environmental pollution factor goal, bined the grain cleaning machine the design to provide the theory basis. This topic group designs the bination grain cleaning machine, after the experimental examination, has the good environmental protection performance, processes the great current capacity grain during the ess not to be able because of the dust which produces but to the environment to cause the pollution and to operates worker's breath health to pose the threat, therefore the bination grain cleaning machine design proposal is reasonable, has the good prospects for development and the market potential.
前言
第一节中国农业机械化的现状及对策
农业机械化是农业现代化的主要内容和重要标志。一个国家农业是否实现现代化,关键在于这个国家农业机械化的程度如何。随着世界经济、科技的发展,我也取得了很大提高,但现在国际经济趋于全球化,我国也即将加入世界贸易组织,我国的农机行业正面临着严峻的考验。我们必须认清我国农机发展薄弱环节,积极寻求农机发展新的方向,才能充分发挥农业机械化在建设我国现代化农业中主力军的作用。以下对我国农机化趋势谈些看法。
作为我国农业现代化的重要组成部分,经过50多年的发展,农业机械化为改变我国传统的农业耕作方式,促进农业由粗放型向集约型转变,促使农村产业结构和农业经济结构的调整、优化的不断深入和完善,起了非常重要的作用,并取得了显著的成绩。随着中国已经进入WTO,农业机械在农业生产中的广度和深度都会有很大提高,农业机械化的作用将得到进一步的发挥,这必将开创我国农机事业的新局面。
