我国玉米秸秆资源丰富,近期玉米秸秆综合利用技术发展很快,自走式穗茎兼收联合收获机应时而生,各生产厂家纷纷介入,产品种类繁多,形式不一。本文简述了玉米秸秆机械化综合利用对我国现代化发展的重要性,以及自走式穗茎兼收联合收获机从秸秆粉碎还田到秸秆铺放抛送,随后发展为不落地式穗茎兼收的发展历程,并列举了各阶段的典型机型主要装置的结构。最后简要分析了目前我国自走式穗茎兼收联合收获机的发展现状及存在问题,提出了开发建议。 China’s corn stalks are rich in resources. The recent comprehensive utilization of corn stalks has developed rapidly. The self-propelled corn stalks and combine harvesters have emerged from time to time. Various manufacturers have stepped in and the products range in different forms. This article describes the comprehensive utilization of corn stalks on the importance of the modernization of our country, as well as self-propelled corn stalks and combine harvesters from straw crushing to straw spreading throwing and throwing, The course of development, and lists the various stages of the typical model of the main device structure. At last, the status quo and existing problems of self-propelled spike-stem combine harvester in our country are briefly analyzed. Suggestions for development are put forward.
