摘要 本文主要討論的是一種精量穴播器的載插機(jī)構(gòu)，該穴播器主要應(yīng)用于煙苗、玉米、甜菜、茄子、蕃茄、棉花等作物的田間移栽作業(yè)。根據(jù)作物育苗移栽的農(nóng)藝要求,在分析了國(guó)內(nèi)外眾多穴播器的基礎(chǔ)上,優(yōu)化設(shè)計(jì)了適合缽苗移栽的機(jī)械的關(guān)鍵部件,分析研究了機(jī)械栽苗的一般規(guī)律,找出了影響栽苗效果的若干因素,確定了工作部件的主要參數(shù)。
該機(jī)構(gòu)的創(chuàng)新點(diǎn)是采用了曲柄連桿機(jī)構(gòu)作為穴播器的投苗機(jī)構(gòu)。由于條件限制,實(shí)踐方面有待進(jìn)一步的加強(qiáng),進(jìn)行進(jìn)一步的檢驗(yàn)、分析、再設(shè)計(jì),使所設(shè)計(jì)的煙苗穴播器械達(dá)到較好的工作性能指標(biāo)和工作可靠性的要求,但最為重要的是一定要滿(mǎn)足農(nóng)業(yè)生產(chǎn)的要求—農(nóng)藝要求。
移栽部件的運(yùn)動(dòng)分析是穴播器設(shè)計(jì)的基礎(chǔ)，在建立缽苗運(yùn)動(dòng)數(shù)學(xué)模型的前提下，運(yùn)用Inventor建立實(shí)體模型，創(chuàng)建組件連接，在Inventor中對(duì)移栽部件進(jìn)行模擬仿真，并對(duì)其關(guān)鍵點(diǎn)與建立的數(shù)學(xué)模型進(jìn)行比較，對(duì)移栽部件參數(shù)進(jìn)行優(yōu)化。
關(guān)鍵詞: 穴播器； 曲柄連桿機(jī)構(gòu)； 投苗機(jī)構(gòu).
Small bowl transplanting seedlings into the onboard computer-aided analysis
Abstract In the thesis, we discuss the seedling launching mechanism of a planter which are applied in transplanting of baccy、corn、beet、eggplant、tomato、cotton ...etc. According to the requirement for agronomy transplantation to grow seedlings, we have found a good method to the ones that are suitable for the baccy nutrition bowl and grow seedlings and transplant in optimization design on the foundation of analyzing numerous transplanting machines both at home and abroad, and through the investigation of the result of the homework, we have analyzed and researched the universal law of the plant shoots in machinery and found some factors that affect the result of plant shoots.
The crank and rocker mechanisms are applied to the seedling launching mechanism. Because the terms is limited, in practice, the aspect treats to further enhance, examination proceeding further, analyze, then design, make a cotton for designing planter attain the good work function index sign and work dependable and reliability, but the most important must satisfy the agriculture produce of request.
Based on analysis of transplanting parts movement, through development of mathematical model describing seedling moving procedure, the entity of transplanting parts were established with software Inventor, and connections of the parts were created. Simulation of planter working procedure was carried out and moving track was set up for study of planter key points in comparison with mathematical model, so the optimum parameters for transplanting parts were obtained.
Key words: planter; crank and rocker mechanisms; seedling launching mechanism.
