摘 要
秸秆纤维的制取一直是生物工程领域关注的问题，本文通过对传统秸秆制取方式和纤维粉碎的各种方法的对比分析，采用机械原理制取微小秸秆纤维，并保证其生产率和纤维质量。
首先通过讨论传统的秸秆纤维粉碎制取的方法，分析各种方法的优点与缺点。综合各种粉碎方法，决定采用两次粉碎的方法制取秸秆纤维，即先用连续冲压模具锤击初步粉碎，再利用锤片式粉碎机二次粉碎。冲压模具的选取上，决定采取牙型模具配合传统空气锤。在众多种类的粉碎机中，通过比较，决定采取锤片式带筛粉碎机，并配合风选系统，提高效率，本文主要进行粉碎机的设计，首先进行结构设计，包括两部分，一个是粉碎部分的结构与功率的设计；二是风选部分的结构与功率的设计。粉碎部分包括锤片的选择，筛网的选择等等，其次进行主轴的校核与轴承的校核。

Manufacture of the straw’s fiber is always the focus which the field of Biological Engineering concern about. The article through contrasting and analyzing the traditional manufacture ways the straw’s fiber and crushing ways of fiber ,it introduces manufacturing of ways the straw’s fiber machinery and ensures its productivity and fibrous quality.
The article discuss the advantage and disadvantage of tradition method which manufacturing fiber of the straw and ways of machinery crush. Comprehensive various method I decide to choice firstly continuous Stamping die to first Smash, and use Hammer mill for again smashing. In the many types of pulverizers, I decided to take hammer-mill with screening by comparison, With the wind-election system for improving efficiency .The article mainly carried out the design of Hammer Mill. First, I must choose design structure .It consists of two parts, One is design of structure and power which smash part; Another is design of structure and power which wind-election system . Smash part include choose hammer, Screen, and so on. Next checking the spindle and bearing.
