9R-28型揉碎机设计
摘要
秸秆是一种潜在的粗饲料资源，我国每年有数千亿斤农作物秸秆被粉碎加工成饲料。饲料工业已经发展成为国民经济中不可缺少的重要基础产业。
9R-28型揉碎机主要用于粗饲料的加工,它集揉切碎和粉碎等机型的优点,可将农作物秸秆、牧草、藤蔓等作物茎杆揉碎成丝状段、既可直接饲喂牲畜,也可将其青贮、氨化、碱化或进行其它加工。
本文针对9R-28型揉碎机进行设计，本文首先分析了揉碎原理，拟定了9R-28型揉碎机的传动方案，采用V带进行增速传动。
然后，对V带传动进行传动设计计算，确定V带的形式及带轮的结构参数。
最后，对整个机器进行了结构设计，重点对机架及转子进行了设计。
本文所设计的揉碎机结构紧凑,性能优良,使用可靠,工作平稳,操作简便,适用范围广,可广泛地满足广大用户要求。

Straw is a kind of potential forage resources, there are hundreds of billions of pounds of crop straw crushed processed into feed everyyear in our country. Feed industry has become an important basic industry indispensable to the national economy.
9R-28 rubbing machine is mainly used for processing of coarse fodder, it incorporates the merits of rubbing and crushing machine chopped, the crop straw, grass, crops such as rubbervine Stem Silk shaped section,which can be directly fed to livestock, and also can be processed for the silage, ammoniation, alkalization or.
In this paper, based on the type of 9R-28 rubbing machine design, this paper first analyzes the principle of the transmission scheme for rubber, 9R-28 rubber, using V belt transmission.
Then, the calculation of the transmission design of V belt drive, determination of V belt and pulley structure parameters.
Finally, thewhole machine structure design, focuses on the design of the frame and the rotor.
Rubbing machine structure is designed in this paper has compact structure, excellent performance, reliable use, stablework, convenient operation,wide application range, can be used to meet the requirements of customers.
Keywords: 9R-28, rubbing machine, V tape drive, the rotor
