机械毕业设计1624玉米灭茬深松机总体设计说明书 - 副本.doc

摘要 设计课题为玉米灭茬深松机总体设计机，来源于生产实际。本设计主要是在普通卧式旋耕机的基础上改进设计,使之既能旋耕又能灭荐，以实现一机多用。设计的主要内容为：总体方案设计、绘制灭茬状态工作总图，设计侧边或中间齿轮传动装置及刀辊轴。 通过改进设计，增加刀辊轴的转速和转向。在工作时，通过适当的拆卸和改装，就可实现不同功能的作业，以达到一机多能的目的。 本课题的实现解决了现有旋耕机只能旋耕不能灭茬而灭茬机又只能灭茬不能旋耕的问题。本课题新颖实用,技术上有较大改进，具有很大的市场前景。 关键词：旋耕灭茬机 侧边传动装置 刀辊轴。 Abstract Design subject rotary tillage stubble cleaner overall for Model and transmission device design by the side, stem from production reality. Is it is it design to improve on the basis of ordinary horizontal rotary tillage machine mainly to design originally, make their can rotary tillage can is it recommend to kill also , in order to realize one machine multi-purpose. The main content designed is: Overall conceptual design , drawing the state job general drawing of the stubble-cleaning , designing by the side or middle gear system and one one hundred sheets of rollers axle . Design through improving, increase the rotational speed of the axle of one one hundred sheets of rollers and change direction. While working, through proper dismantlement and repacking , can realize the homework of different functions , in order to be up to a machine multi-functional purpose . Can can only solve rotary tillage not existing of rotary tillage of stubble-cleaning of realizations of subject but stubble cleaner can only stubble-cleaning can problem of rotary tillage. This subject is novel and practical, there is greater improvement technically , have very great market prospects. Keywords: Rotary tillage stubble cleaner ; Transmission device by the side; Axle of one one hundred sheets of rollers. 目录 摘要 I Abstract II 前言 IV 1 设计的目的及内容 1 2 方案的拟定 2 2.1设计参数要求 2 2.2方案的选择 2 2.3方案对比分析 4 3 灭茬机的总体设计 5 3.1拖拉机的选择 5 3.2灭茬机的工作原理 5 3.3灭茬机与拖拉机的挂接 5 3.4灭茬机与拖拉机的配置型式 6 3.5灭茬机耕幅的确定 6 3.6灭茬机的传动型式的选择 6 3.7灭茬机的刀轴转速选定 6 4 运动计算 7 5 动力计算 8 5.1各传动副效率 8 5.2动力分配 8 6 主要零部件的设计 11 6.1锥齿轮箱的结构 11 6.2刀辊的结构 11 6.3灭茬刀的设计 12 6.4刀座的轴向间距和刀的总数 14 6.5材料和技术条件 14 7 深松部件 15 7.1深松铲的设计 15 7.2铲柄设计 15 7.3深松铲 16 7.4机架 17 7.5牵引架的设计 17 7.6深松铲机架的设计 17 7.7限深装置的设
