青饲料切割机的设计
                   
   
    摘  要: 一种青饲料切割机,由装在同一传动轴上的破碎,切碎两种功能的机构构成.破碎机构主要由刀齿板、切刀、刮刀及辊筒构成.加工块茎类物料时,经刀齿的划割,切刀的切割,刮刀的进一步破碎,完成加工过程;同时,可利用切碎机构加工藤蔓、杆叶类青饲料;并采用辊压轮对藤蔓进行自动进给.拆下破碎部件,换上磨碎齿板,又可作为薯类淀粉初加工机具.因此,既能满足青饲料加工要求,又能加工薯类淀粉,适应农村养殖业的需要.
    关键词: 破碎、切碎、切刀、辊筒、辊压轮

Green fodder cutting machine design
                      

    Abstract：A green fodder cutting machine ,by the same equipment on the drive shaft broken, shredding function of the two bodies constituted . Broken bodies is main made up of plate cutters, machetes, blade and roller. Tuber processing materials, with the cutter tooth is removed, the cutter cutting, scraping further broken completed processing . Meanwhile, it will use the sap processing shredding bodies, leveraged leaf green fodder,and using roller round to get the sap Automatic Feed . Broken parts removed and replaced teeth grinding plate, and could serve as the beginning of potato starch processing machines , Therefore, it can satisfy green fodder processing requirements, while potato starch processing, aquaculture industry suitable to rural needs .
    Key Words：Breakers;Shredding;Cutter;Roller ;Rolling wheel
