計(jì)的工作過(guò)程;同時(shí)在AutoCAD的基礎(chǔ)上,對(duì)該系統(tǒng)的裝配圖和部分零件圖進(jìn)行了繪制。 Foshan University本科生畢業(yè)設(shè)計(jì) 椰子剝殼機(jī)的設(shè)計(jì)學(xué) 院: 機(jī)械與電氣工程學(xué)院 專 業(yè): 機(jī)械設(shè)計(jì)制造及其自動(dòng)化 學(xué) 號(hào): 學(xué)生姓名: 指導(dǎo)教師: 二 〇 一 三年 六 月摘 要 椰子內(nèi)含果肉和椰子水,具有豐富的油脂、蛋白質(zhì)等營(yíng)養(yǎng)物質(zhì),且椰衣可以加工成纖維墊、繩索等,具有很高的綜合應(yīng)用價(jià)值。關(guān)鍵詞:椰子;剝殼; solidworks;motion運(yùn)動(dòng)仿真;AutocadⅡDesign of the Husking Machine of coconutShen HongfeiAbstractCoconut and coconut water contains pulp, with rich oil, protein and other nutrients, and can be processed into coconut fiber mat clothing, ropes, etc., with a high value of integrated applications. The peel is a coconut processing is a very important part, so the design is to design a high degree of mechanization coconut husking machines, coconut husking can improve production efficiency.The design on the basis of access to information, through the choice of different options to determine the peel of the driveline program for coconut sheller design. The design of the system through a gear, gear roller, shaft, baffles, pressure frame means, feed devices, structural design and with the design, the final pletion of the various ponents with the assembly, through the threedimensional software solidworks, for assembly, and with motion simulation demonstrates the form of the work of the design process。 Solidworks。種仁供食用,故稱椰肉,占全果質(zhì)量的28%~30%,為椰殼所包覆,富含油脂、蛋白質(zhì)等營(yíng)養(yǎng)成分。 我國(guó)椰子加工主要集中在海南,有加工企業(yè)近300家,已經(jīng)成為海南的重要產(chǎn)業(yè)。在國(guó)內(nèi)的椰子剝殼機(jī)研究起步比較早,市場(chǎng)上也有許多椰子剝殼機(jī),但成熟的椰子剝殼機(jī)卻很少見(jiàn)。該椰子剝殼機(jī)的主要技術(shù)參數(shù)如表11。圖21 方案一 方案二中,系統(tǒng)原理如圖22所示,起初投入的椰子5落在傾斜的剝殼頂板1上,由于刀片接觸支撐,然后左側(cè)豎直釘板沿X方向運(yùn)動(dòng)適當(dāng)距離使刀片扎入椰子,右側(cè)傾斜釘板沿Y向運(yùn)動(dòng)使兩個(gè)釘板上的刀片滾切揉搓椰子,Y向移動(dòng)超過(guò)普通椰子半周的適當(dāng)距離。椰子從進(jìn)料口進(jìn)入剝殼通道,兩齒輥平行布置且相向轉(zhuǎn)動(dòng),齒輥表面上安有齒釘,椰子在齒輥的帶動(dòng)下,邊轉(zhuǎn)邊前行,椰衣逐漸被齒釘所刺破,并從椰子內(nèi)果上剝離,從而實(shí)現(xiàn)椰子剝殼[3]。電機(jī)的型號(hào)選擇于參數(shù)如圖24圖24 電機(jī)選擇參數(shù)圖表3.椰子剝殼機(jī)的結(jié)構(gòu)設(shè)計(jì)由選的擺線針輪減速電機(jī)型號(hào)知,電機(jī)輸入軸的直徑D=45mm;由于,查設(shè)計(jì)手冊(cè),選聯(lián)軸器型號(hào)為:該聯(lián)軸器傳遞的公稱力矩Tn=500 N故采用脂潤(rùn)滑。 (35)代入數(shù)據(jù),解得: ;考慮磨損的影響增大模數(shù)1
