摘 要
本文對(duì)玉米種植意義、玉米耕作方式的現(xiàn)狀及未來(lái)發(fā)展趨勢(shì)、玉米播種機(jī)械發(fā)展歷程與特點(diǎn)進(jìn)行分析和介紹，同時(shí)對(duì)玉米聯(lián)合播種機(jī)的市場(chǎng)需求及現(xiàn)有產(chǎn)品進(jìn)行調(diào)查分析，分析2BFH-4型玉米滅茬種肥聯(lián)合播種機(jī)的市場(chǎng)前景。2BFH-4型玉米滅茬種肥聯(lián)合播種機(jī)在秸稈滅茬還田的同時(shí)施肥播種，實(shí)現(xiàn)了免耕播種，不僅提高工作效率，而且節(jié)省了成本。該機(jī)型設(shè)計(jì)新穎，結(jié)構(gòu)緊湊，操作簡(jiǎn)單，符合環(huán)保要求，工作效率高，滅茬率高等優(yōu)點(diǎn)，是一種國(guó)內(nèi)比較先進(jìn)的玉米聯(lián)合播種機(jī)機(jī)型。本文為2BFH-4型玉米滅茬種肥聯(lián)合播種機(jī)滅茬機(jī)構(gòu)結(jié)構(gòu)設(shè)計(jì)，滅茬機(jī)構(gòu)作為聯(lián)合播種機(jī)的重要組成部分，是實(shí)現(xiàn)免耕播種的前提條件，動(dòng)力由配套拖拉機(jī)提供，采用三點(diǎn)懸掛方式與配套拖拉機(jī)連接，考慮到滅茬作業(yè)需要較大的功率輸入，且作業(yè)環(huán)境較差，采用具有傳動(dòng)可靠且效率較高的齒輪傳動(dòng)裝置，滅茬方式采用刀具于刀盤之上共同旋轉(zhuǎn)滅茬。根據(jù)整機(jī)的參數(shù)確定滅茬結(jié)構(gòu)的外形尺寸。根據(jù)設(shè)計(jì)的原始參數(shù)，設(shè)計(jì)校核傳動(dòng)裝置、作業(yè)裝置及其他輔助裝置，最后根據(jù)設(shè)計(jì)尺寸進(jìn)行滅茬機(jī)構(gòu)的二維工程圖繪制。

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 corn combine 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, environmental compliance, 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 the common rotary cutter stubble. According to the parameters of machine dimensions to determine the structure of stubble. According to the original design parameters, design checking gear, working equipment and other assistive devices, according to the design size of the final stubble institutions drawing two-dimensional works.
Keywords: 2BFH-4 Corn joint planter; stubble institutions; gear drive; two-dimensional engineering drawings
