摘　　要：农作物秸秆微粉碎后可实现高品质精细化利用,文章基于发明问题解决理论(TRIZ)进行了秸秆微粉机的概念设计,提出了多层动定刀冲击、剪切、摩擦的复合粉碎方式,应用系统功能分析、物场分析、技术矛盾、物理矛盾、最终理想解、聪明小人法、功能导向搜索等TRIZ工具对秸秆微粉机的粉碎机构、喂入机构和分离收集机构进行创新设计,研究成果为提高秸秆微粉碎效率和降低粉碎粒度提供了参考。High-quality and refined utilization of crop straws can be achieved after micro-pulverization.The conceptual design of straw micro pulverizer was carried out based on the Inventive Problem Solving Theory(TRIZ),a composite crushing method of impact-shearing and friction with multi-layer moving and fixed cutter was proposed.Using TRIZ tools such as system function analysis,substance-field analysis,technical contradiction,physical contradiction,ideal final result,smart little people and function-oriented search,the crushing mechanism,feeding mechanism,separation mechanism and collection mechanism of straw micro pulverizer were innovatively designed,it provided a reference for improving the micro pulverizing efficiency of straw and reducing the size of pulverization.
