【正文】 本 科 畢 業(yè) 論 文（設(shè) 計）摘 要：鐵筋砂輥碾米機是一種傳統(tǒng)的碾米機，主要用來把稻谷直接碾成白米，并將米、細糠、小碎米、谷嘴自動分離，不需要經(jīng)風(fēng)車或篩子分離。鐵筋碾米機與同類型其他碾米機相比較，具有高產(chǎn)量，低電耗的優(yōu)點。本機結(jié)構(gòu)緊湊，操作簡便，安裝輕易，設(shè)有除塵裝置，用于集糠并減少環(huán)境污染，性能優(yōu)越，工作可靠，是廣大農(nóng)村、集鎮(zhèn)稻谷加工的優(yōu)良機械。關(guān)鍵詞：鐵筋；砂輥筒；米刀；米篩；米糠分離 The Design of iron bars sand of roller rice millAbstract:Abstract: The iron bars sand of roller rice mill is a tradition rice mill, mainly used to direct ground into rice paddy and rice, fine bran and small broken rice, grain mouth automatically separate, or do not need to sieve through windmill milling machine and milling machine is pared with otherstypes,high yield low power consumption advantages.The machine structure is pact, easy to operasy ,install easily,with dust removal device for the collection bran and reduce envir onmental pollution,superior performance,reliable operation,is the vast rural areas,market towns fine rice processing machinery.鐵筋砂輥碾米機畢業(yè)設(shè)計2Keywords:iron bars。 wind。sand ofroller。meters knives。msieve。rice bran separation. 目錄一、緒 論 .......................................................................................................................4 碾米工業(yè)在國民經(jīng)濟中的作用和地位 ...........................................................4 我國碾米工業(yè)的發(fā)展史 ...................................................................................4 碾米工業(yè)的任務(wù) ...............................................................................................4二、碾米的基本原理及機型 .........................................................................................5 碾米的基本原理 ...............................................................................................5 碾米機的分類 ...................................................................................................6三、設(shè)計方案和參數(shù)選擇 ...........................................................................................10 機型選擇： .....................................................................................................10 立式碾米機的優(yōu)缺點 ...........................................................................10 臥式碾米機的優(yōu)缺點 ...........................................................................10 各種參數(shù)的選擇 .............................................................................................11 碾白壓力 ............................................................................................11 單位產(chǎn)量碾白運動面積 ....................................................................12 向心加速度 ........................................................................................13四、碾米機的結(jié)構(gòu)設(shè)計 ...............................................................................................15 進料裝置 .........................................................................................................15 碾白室 .............................................................................................................18 排料裝置 .........................................................................................................22 傳動部分 .........................................................................................................23五 、碾米機的操作與維護 .........................................................................................24 碾米機的操作調(diào)整 .........................................................................................24 碾米機的維護保養(yǎng) .........................................................................................26八、參考文獻 ...............................................................................................................28致謝鐵筋砂輥碾米機畢業(yè)設(shè)計3一、緒 論 碾米工業(yè)在國民經(jīng)濟中的作用和地位 碾米工業(yè)是糧油工業(yè)的重要組成部分。我國稻谷產(chǎn)量占世界第一位，全國約有三分之二的人口以稻谷為主要食糧。稻谷含有大量淀粉，還含
