,切碎兩種功能的機(jī)構(gòu)構(gòu)成。破碎機(jī)構(gòu)主要由刀齒板、切刀、刮刀及輥筒構(gòu)成。同時(shí) ,可利用切碎機(jī)構(gòu)加工藤蔓、稈葉類(lèi) 。拆下破碎部件 ,換上磨碎齒板 ,又可作為薯類(lèi)淀粉初加工機(jī)具。 關(guān)鍵詞 : 破碎 。 輥筒 II Hay Cutter Machine Design Abstract This project is to design a hay cutter machine , in the same transmission from the broken, which is chopped two functions of institution. Crushing institutions is mainly by the cutter tooth board, cutting knife, scraper and rollers material processing tubers. Whe
