As is known to all, straw contains a huge amount of energy, as an agricultural country, it is necessary for us to carry out these straw energy utilization. The current widespread use of the technology of straw is straw returning, the straw pulverizer has put forward higher requirements.This paper summarizes the advantages and disadvantages of the existing straw crusher, aiming at the current problems, based on the working principle and structure characteristics of researches on the straw pulverizer, bined with the actual situation, design a straw crusher hammer.This design is mainly posed of a transmission mechanism, a crushing mechanism and a discharging port of three parts. Study on the belt drive, the crushing chamber, rotor, inlet and outlet and the frame ponents by mechanical design, mechanical principle and other related professional knowledge carries on the stress analysis and design calculation of the size and checking, finally using AutoCAD to draw the parts diagram and the whole machine assembly.Keywords：Hammer mill。本設(shè)計(jì)主要由傳動(dòng)機(jī)構(gòu)、粉碎機(jī)構(gòu)和進(jìn)出料口三部分組成。目前普遍采用的技術(shù)是秸稈還田，這就對(duì)秸稈粉碎機(jī)提出了更高要求。本 科 畢 業(yè) 設(shè) 計(jì) 題 目 秸稈粉碎機(jī)的設(shè)計(jì)姓 名 學(xué) 號(hào)專(zhuān) 業(yè) 機(jī)械設(shè)計(jì)制造及其自動(dòng)化指導(dǎo)教師 職 稱(chēng) 二〇一五年 六月分類(lèi)號(hào) 密級(jí) 本 科 畢 業(yè) 論 文 秸 稈 粉 碎 機(jī) 的 設(shè) 計(jì)The design of the straw pulverizer 學(xué)生姓名： 學(xué)生學(xué)號(hào)：學(xué)生專(zhuān)業(yè)： 機(jī)械設(shè)計(jì)制造及其自動(dòng)化指導(dǎo)教師：工學(xué)院二〇一五年 六月 秸稈粉碎機(jī)的設(shè)計(jì)I摘要 2022 年，我國(guó)的農(nóng)村秸稈產(chǎn)量已達(dá)到 億噸，位居世界前列。眾所周知，秸稈中蘊(yùn)藏著巨大的能源，作為農(nóng)業(yè)大國(guó)，我們有必要將這些秸稈中的能量進(jìn)行加工利用。本文通過(guò)對(duì)現(xiàn)有秸稈粉碎機(jī)的優(yōu)缺點(diǎn)進(jìn)行闡述總結(jié)，針對(duì)目前仍存在的問(wèn)題，在分析研究已有秸稈粉碎機(jī)的工作原理及結(jié)構(gòu)特點(diǎn)的基礎(chǔ)上，結(jié)合實(shí)際情況，設(shè)計(jì)出一種錘片式秸稈粉碎機(jī)。研究中，對(duì)帶傳動(dòng)、粉碎室轉(zhuǎn)子、進(jìn)出料口及機(jī)架等所需零部件利用機(jī)械設(shè)計(jì)、機(jī)械原理等相關(guān)專(zhuān)業(yè)知識(shí)進(jìn)行受力分析從而設(shè)計(jì)計(jì)算其各尺寸并進(jìn)行校核，最后利用 AutoCAD 畫(huà)出各個(gè)零部件圖及整機(jī)裝配圖。 Transmission mechanism。 AutoCAD華中農(nóng)業(yè)大學(xué) 2022 屆本科畢業(yè)論文II目錄摘要......................................................................................................................................I關(guān)鍵詞..................................................................................................................................IABSTRACT..............................................................................................................................IKEYWORDS..............................................................................................................................I1 緒論..................................................................................................................................1 課題背景..............................................................................................................1 文獻(xiàn)綜述..............................................................................................................1 秸稈粉碎機(jī)的分類(lèi)..................................................................................1 錘片式粉碎機(jī)的現(xiàn)狀分析......................................................................2 秸稈粉碎機(jī)的應(yīng)用前景..........................................................................32 錘片式秸稈粉碎機(jī)的工作原理......................................................................................4 粉碎機(jī)的工作原理分析......................................................................................4 粉碎機(jī)理分析..........................................................................................4 粉碎機(jī)工作原理......................................................................................5 錘片式秸稈粉碎機(jī)的研究?jī)?nèi)容..........................................................................53 錘片式秸稈粉碎機(jī)的總體結(jié)構(gòu)及設(shè)計(jì)計(jì)算..................................................................6 秸稈粉碎機(jī)的總體結(jié)構(gòu)......................................................................................6 秸稈粉碎機(jī)整機(jī)的設(shè)計(jì)計(jì)算..............................................................................6 電機(jī)選型及扭矩計(jì)算..............................................................................6 電機(jī)選型..................................................................................6 扭矩計(jì)算..................................................................................7 帶傳動(dòng)的設(shè)計(jì)計(jì)算及選型......................................................................7 粉碎室主軸的設(shè)計(jì)計(jì)算........................................................................10 錘片的設(shè)計(jì)、選材及排列....................................................................13 錘架板的設(shè)計(jì)選材................................................................................15 銷(xiāo)軸的設(shè)計(jì)計(jì)算....................................................................................16 套筒的設(shè)計(jì)............................................................................................17秸稈粉碎機(jī)的設(shè)計(jì)III 機(jī)架、機(jī)殼及進(jìn)、出料口的設(shè)計(jì)........................................................184 主軸的校核、鍵的校核及軸承壽命驗(yàn)算.....................................
