文档介绍：2BFH-4型玉米灭茬种肥联合播种机灭茬机构结构设计
摘要
本文对玉米种植意义、玉米耕作方式的现状及未来发展趋势、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。2BFH-4型玉米灭茬种肥联合播种机在秸秆灭茬还田的同时施肥播种,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,符合环保要求,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2BFH-4型玉米灭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,灭茬方式采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。

Significance of this paper, corn, corn tillage situation and future development trends, development process of corn planting and mechanical characteristics of the analysis and presentation, while the market demand for bine seeder investigation and analysis of existing products, analysis 2BFH-4 type United corn stubble seed fertilizer seeder market prospects. 2BFH-4 types of fat corn stubble straw stubble in the joint drills to field planting, while fertilization to achieve the no-tillage sowing, not only to improve efficiency and cost savings. The model design, compact structure, easy operation, pliance, high efficiency, high stubble, etc., is a joint domestic corn planter more advanced models. This article The Stubble body structure design of 2BFH-4 species of corn stubble United seeder fertilizer, planter stubble institutions as an important part of the joint is a prerequisite for achieving no-till seeding, power provided by the supporting tractor, using three methods and the suspension supporting the tractor connection, taking into account the need for larger power tiller operation input, and the poor working environment, using a reliable and efficient transmission gearing, means using the tool in the stubble on mon rotary cutter stubble. According to the parameters of machine dimensions to determine the structure of stubble. According to the origina
