我国玉米种植面积大,分布广,玉米机收率提高以后,玉米摘穗收获成为一种过渡收获方式,子粒收获将是玉米收获机的发展方向。玉米子粒收获方式分为两种:一种是摘穗脱粒收获,在欧美国家已成为成熟的玉米收获技术;另一种是全喂入脱粒收获,与其他谷物收获机械一样,将茎秆在脱谷室内打碎排出机外,果穗脱成子粒送入粮仓。该文重点阐述通过改装和换装小麦收获机的部分工作部件,实现全喂入玉米子粒收获这一过程中,几种关键部件的试验、研究和设计结果。
Corn planting area in China is large, widely distributed, corn machine yield increased later, the harvest of corn harvesting as a transitional harvesting method, grain harvest will be the development direction of the corn harvester. Harvesting methods of corn is divided into two kinds: one is picking ears threshing harvest, in Europe and the United States has become a mature corn harvesting technology; the other is fully fed threshing harvest, and other grain harvesting machinery, the stalks off Valley indoor smashed discharge machine, into the granary grain into the granary. This article focuses on the experimental, research, and design results of several key components in the process of full-feed corn harvest by modifying and replacing part of the working parts of a wheat harvester.
