摘 要
自从我国加入世界贸易组织以来，我国获得一个更加稳定的国际贸易环境，各行各业都面临着重大的机遇和挑战，肥料行业也不例外，BB肥作为实现测土配方施肥的重要肥种，越来越受到各方面的重视，中华合作时报·农资专刊顺应时势发展，组织业内精英共聚一堂、各抒己见，共同探讨中国BB肥行业的发展思路，如果说第一届BB肥行业发展论坛的胜利召开为我们指明了发展目标，那么此届发展论坛的召开应该是探讨达到这个目标我们所需要做的努力。
中国BB肥行业的发展正处在一个十分关键的时期，面临着各种机遇和挑战，机遇就是党和政府对“三农”问题的高度重视、社会主义新农村建设、国家对测土配方施肥工程的大力提倡，社会大环境给BB肥提供了广阔的发展空间，农资人的睿智为BB肥描绘了光明的发展前景，但是还要看到，随着市场经济对农资行业的浸透，WTO保护期的结束，国外农资大鳄对中国农资的分销市场早已垂涎已久，我国化肥行业面临着前所未有的挑战。中国化肥行业，特别是BB肥行业，应该团结起来、发挥整体优势，做大自己，抵御来自国外BB肥的强烈冲击。涅盘之后得到的将是永生。
这样，BB肥生产设备在我国也必然有很好的发展前景，本设计课题是（9-BBⅡ型）BB肥生产设备总体设计及传动系统设计。这个课题主要包括总体方案的确定和传动系统尺寸的确定及计算。完成这个课题，能够让我们学会如何将课堂上所学的理论知识更好的应用到社会实践中去。
由于水平有限。本论文中必然存在不少纰漏和错误，敬请评阅老师们批评指正。

Abstract
Since Chinese accession to the World Trade Organization, China access to a more stable international trading environment, businesses are faced with major opportunities and challenges, the fertilizer industry is no exception, BB fertilizer soil testing as an important fertilizer Fertilization species, the more to more attention from all sides, the Chinese co-operation conform to the trend of the times Times special agricultural development, the industry's elite organizations together to express their views and to discuss China's fertilizer industry BB thinking, if we say that the first Development Forum BB fertilizer industry victory held for us a clear development goals, so this session should be convened to develop the Forum is to explore to achieve this objective we need to do efforts.
BB fertilizer Industry in China's development is at a very critical period, facing a variety of opportunities and challenges, opportunities and the government is the party of "Three Rural Issues" attached great importance to building a new socialist countryside, the state soil testing Fertilization a strong proponent of the project, social environment to BB fertilizer provides a broad space for development of human wisdom for agricultural fertilizer BB painted a bright future, but would also like to see, with the market economy on the agricultural industry immersion, the end of protection period WTO, foreign agricultural predators of the distribution of China's agricultural market has long been coveted for a long time, China's fertilizer industry is faced with unprecedented challenges. China's chemical fertilizer industry, in particular, BB fertilizer industry should unite together to play the whole advantage of their big, fat BB from abroad against a strong impact.
So, BB fertilizer production facilities in China are bound to have good prospects for the development, the design issue is (9-BB Ⅱ type) BB fertilizer production equipment design and drive system design. The main subject of the overall program, including the identification and determination of transmission and calculation of the size. The completion of this subject, can we learn how to learn in class by the application of theoretical knowledge to the society a better practice.
In this paper, there is bound to be a lot of fault and error please comment criticism teachers.
