微型玉米剝皮機(jī)設(shè)計(jì)255

塔里木大學(xué)畢業(yè)設(shè)計(jì) 所以：所需電動(dòng)機(jī)功率為3kW。而電動(dòng)機(jī)的轉(zhuǎn)速要求應(yīng)為1440r/min，且要考慮農(nóng)村現(xiàn)有情況，要選用單相交流電，而三相交流相對來說不方便，所以采用Y100L1—4型單相電動(dòng)機(jī)。7總結(jié)雖然在設(shè)計(jì)中還存在很多不完善的地方，但在整個(gè)設(shè)計(jì)過程中，我的收獲很大，學(xué)到了很多。在這幾個(gè)月的時(shí)間中，在老師的耐心指導(dǎo)下，經(jīng)過反復(fù)修改，終于完成了設(shè)計(jì)。四年的大學(xué)生活即將結(jié)束，這次設(shè)計(jì)部僅僅是一次完成學(xué)業(yè)的重要環(huán)節(jié)，也是系統(tǒng)學(xué)習(xí)的好機(jī)會(huì)。因此畢業(yè)設(shè)計(jì)是綜合運(yùn)用所學(xué)知識和技能，理論聯(lián)系實(shí)際，獨(dú)立分析、解決實(shí)際問題，從事專業(yè)工程技術(shù)和科學(xué)研究工作基本訓(xùn)練的過程。畢業(yè)設(shè)計(jì)為我走出校園進(jìn)入工作崗位打下了良好的基礎(chǔ)，畢業(yè)設(shè)計(jì)不像以前的各科課程設(shè)計(jì)那樣只是按照一定得樣本區(qū)模仿，它是展現(xiàn)自我才智，發(fā)揮見解和創(chuàng)造能力的機(jī)會(huì)。在鞏老師的精心指導(dǎo)和耐心講解下，我所學(xué)的基礎(chǔ)知識和專業(yè)知識得到了充分的運(yùn)用，同時(shí)我的基礎(chǔ)知識掌握的也不是很牢固，范老師也指出了我基本思想中存在的很多錯(cuò)誤。以后我要更加的努力學(xué)習(xí)我的專業(yè)知識，在自己今后的工作生活中多運(yùn)用所學(xué)的知識，使自己得到更多鍛煉機(jī)會(huì)。在這幾個(gè)月的時(shí)間中，我在網(wǎng)上查閱了一些有關(guān)的設(shè)計(jì)資料，而且參閱了大量有關(guān)期刊，從中了解到了許多相關(guān)信息及設(shè)計(jì)所需的數(shù)據(jù)，從而使我順利的完成了畢業(yè)設(shè)計(jì)。我所做的畢業(yè)設(shè)計(jì)是小型玉米剝皮機(jī)，該機(jī)結(jié)構(gòu)簡單，調(diào)整方便，性能可靠，生產(chǎn)效率高，主要?jiǎng)兤ぱb置采用全橡膠的玉米剝皮輥，這避免了傳統(tǒng)設(shè)計(jì)方法中采用鑄鐵輥對玉米籽粒的損壞，而且在結(jié)構(gòu)上比傳統(tǒng)設(shè)計(jì)方法更為合理。并且在剝皮裝置與傳動(dòng)方式上較傳統(tǒng)設(shè)計(jì)有所改進(jìn)，更適于在廣大農(nóng)村的推廣應(yīng)用。在整個(gè)設(shè)計(jì)過程中，我的CAD操作也日漸熟練，這對我日后的工作來說也有著莫大的好處。通過這次設(shè)計(jì)，我對機(jī)械設(shè)計(jì)的各個(gè)環(huán)節(jié)有了更加深刻的了解，對所學(xué)的專業(yè)知識有了更好的掌握，對四年所學(xué)的基本知識都系統(tǒng)的回顧并掌握了，使我充分動(dòng)腦，充分發(fā)揮想象力，經(jīng)老師知道最后確定了設(shè)計(jì)方案，這次設(shè)計(jì)是一次很好的學(xué)習(xí)與思考的過程，在本次設(shè)計(jì)過程中所獲得這些將在今后的工作中發(fā)揮基礎(chǔ)和平臺的作用。由于我的知識水平有限，在設(shè)計(jì)中存在一定得問題，請?jiān)u閱老師見諒，并懇請各位老師批評指正。致謝對于這次畢業(yè)設(shè)計(jì)的完成，首先感謝我的母校-塔里木大學(xué)的辛勤培育，感謝學(xué)校給了我又一次如此難得的學(xué)習(xí)機(jī)會(huì)，使我將以前學(xué)到的科學(xué)文化知識又重新回顧了一遍，明白了學(xué)習(xí)的可貴與獲取知識的辛勤。在此感謝我的指導(dǎo)老師范修文老師的耐心指導(dǎo)，使我順利地完成了畢業(yè)設(shè)計(jì)。在此，深深地感謝我的指導(dǎo)老師，給予了我耐心的指導(dǎo)和幫助，體現(xiàn)出了他對工作高度負(fù)責(zé)的精神。在整個(gè)設(shè)計(jì)的過程中，他耐心的指導(dǎo)，才使我的設(shè)計(jì)順利完成，同時(shí)也感謝在這幾年中傳授我知識的各位老師。謝謝你們！對于這次畢業(yè)設(shè)計(jì)，由于時(shí)間倉促和自己所學(xué)軟件掌握熟練程度等因素，使這次畢業(yè)設(shè)計(jì)的平面圖沒有達(dá)到預(yù)期效果，這點(diǎn)是我的錯(cuò)誤。不過，它至少啟發(fā)了我的思維，提高了我的動(dòng)手能力，使我應(yīng)用了以前Solidworks軟件中沒有用到的工具，同時(shí)，使我將以前所學(xué)的書本知識又重新復(fù)習(xí)了一遍，這為我在今后的工作崗位上發(fā)揮自己的才能奠定了堅(jiān)實(shí)的基礎(chǔ)。最后，再一次衷心的感謝學(xué)校能夠給予我這次機(jī)會(huì)，使我將所學(xué)理論知識與實(shí)踐相結(jié)合，以及在這次設(shè)計(jì)中給予我指導(dǎo)的所有老師。你們傳授的知識使我受用一生，你們的教育之情我會(huì)永遠(yuǎn)記住的，我也會(huì)永遠(yuǎn)記住塔里木大學(xué)給了我難得的學(xué)習(xí)機(jī)會(huì)給了我知識，老師的辛勤培育使我能順利走出學(xué)校進(jìn)入社會(huì)，在人才濟(jì)濟(jì)的社會(huì)中生存，正是有了無私奉獻(xiàn)的老師們這個(gè)社會(huì)才更加繁榮和諧，在此我再次感謝我的老師，老師們你們辛苦了！參考文獻(xiàn)[1]王先霞,倪長安,劉師多.玉米果穗剝皮裝置影響剝皮性能的試驗(yàn)分析[J].農(nóng)機(jī)化研究2003.[2]賈秀芝,季英．玉米穗剝皮機(jī)性能試驗(yàn)[J]．農(nóng)機(jī)質(zhì)量與監(jiān)督2004.[3]趙德春,呂金慶,盛力偉．玉米剝皮機(jī)的研究設(shè)計(jì)[J].農(nóng)機(jī)化研究,2001.[4]高彥文,張明源,范崇全.玉米收獲機(jī)的剝皮機(jī)構(gòu)[J].現(xiàn)代化農(nóng)業(yè),1996,16-20.[5]李秀清,張憲宏.玉米剝皮機(jī)構(gòu)探討[J].糧油加工與食品機(jī)械,1997,6.[6]賈秀枝,季英.玉米剝皮機(jī)性能試驗(yàn)[J].農(nóng)機(jī)質(zhì)量與監(jiān)督,2007,18-30.[7]呂建文,李謙緒.玉米剝皮機(jī)錐齒輪傳動(dòng)的改進(jìn)[J].新疆農(nóng)計(jì)化,2004,36-52.[8]李紀(jì)萍.微型玉米剝皮機(jī)膠輥部件的設(shè)計(jì)研究[J].農(nóng)機(jī)推廣與安全,2005,78-88.[9]吳宗澤,羅圣國.機(jī)械設(shè)計(jì)課程設(shè)計(jì)手冊[M].[10]肖銀玲,金輝,朱靜.機(jī)械制圖[M].[11]孫桓,陳作模,葛文杰.機(jī)械原理[M].[12]紀(jì)名剛,陳國定,吳立言.機(jī)械設(shè)計(jì)[M].aganemploymenttribunalclaiEmloymenttribunalssortoutdisagreementsbetweenemployersandemployees.Youmayneedtomakeaclaimtoanemploymenttribunalif:youdon'tagreewiththedisciplinaryactionyouremployerhastakenagainstyouyouremployerdismissesyouandyouthinkthatyouhavebeendismissedunfairly.Formoreinformu,takeadvicefromoneoftheorganisationslistedunder
