1、2BFH-4型玉米灭茬种肥联合播种机灭茬机构结构设计本文对玉米种植意义、玉米耕作方式的现状及未來发展趙势、玉米播种机械发展历程与特点进行分析和介绍，同时对玉米联合播种机的市场需求及现有产品进行调查分析，分析2BFH-4型玉米灭茬种肥联合播种机的市场前景o2BFH-4型玉米灭茬种肥联合播种机在秸秆灭茬还R1的同时施肥播种，实现了免耕播种，不仅提高工作效率，而且节省了成本。该机型设计新颖，结构紧凑，操作简单，符合坏保要求，工作效率高，灭茬率高等优点，是一种国内比较先进的玉米联合播种机机型。本文为2BFII-4型玉米灭
2、茬种肥联合播种机灭茬机构结构设计，灭茬机构作为联合播种机的重要组成部分,是实现免耕播种的前提条件，动力由配套拖拉机提供，采用三点悬挂方式与配套拖拉机连接，考虑到灭茬作业需要较大的功率输入，且作业环境较差，采用具有传动可靠且效率较高的齿轮传动装置，灭茬方式釆用刀具于刀盘之上共同旋转灭茬。根据整机的参数确定灭茬结构的外形尺寸。根据设计的原始参数，设计校核传动装置、作业装置及其他辅助装置，最后根据设计尺寸进行灭茬机构的二维工程图绘制。关键词：玉米；播种机；灭茬；免耕播种TheStubblebodystructurede
