适用于全喂入联合收割机的1JHSX-34型秸秆粉碎机设计

Design of 1JHSX-34 straw crusher for whole-feeding combine harvesters

摘要: 配套全喂入式联合收割机的秸秆粉碎机具目前缺乏。该文设计了一款适合于全喂入联合收割机的1JHSX-34型双轴式秸秆粉碎机。文中详细介绍了整机结构和工作原理，重点针对粉碎刀轴转速、刀片和传动系统的设计进行了详细的阐述。通过对3种不同倒伏率（90%，50%，0）的小麦田间试验显示：小于50mm长度的秸秆粉碎平均合格率分别为91.3%、92.9%和94.4%。试验结果表明，双轴式秸秆粉碎机性能良好。

Abstract: Supporting equipments for the whole-feeding combine harvester of straw crusher were lack. 1JHSX-34 straw crusher for whole-feeding combine harvesters was designed in this paper, and structure and working principle of the1JHSX-34 straw crusher were introduced. Shaft speed, blade parameters and drive system were analyzed in detail. Three different lodging rate of wheat field (90%, 50%, 0) test showed that stalk crushing average qualified rate of less than 50 mm length respectively were 91.3%, 92.9% and 94.4%. The results show that straw crusher performance is good.
