摘要
阐述了4LYB1-2.0型油菜联合收获机的总体结构,以及伸缩割台、脱粒分离、清选装置等主要工作部件的设计。田间性能测试表明:该机总损失率为5.7%、破碎率0.3%、含杂率2%,各项技术指标达到了油菜机械化收获的要求。
With the improvement of variety and the extension of applying field, the rape planting area increased continuously in recent years. Rape harvesting by hand consumed much time and labor, which resulted in high loss rate of rapeseed and the hard labor intensity. And the existing rape harvesters were mainly refitted from rice-wheat harvester and the working performance was still at a low level. At the end of 2007, the ratio of machine harvest rape area was only 216 % in China. The structure of model 4LYB1 -2.0 whole-feeding rape combine harvester was introduced. The design proceeding of the key parts including header, threshing and separating unit and cleaning unit were described in detail. Experiments were made in Zhenjiang, Jiangsu province, which showed that the total loss rate was 5.7 %, broken rate 0.3 %, and impurity rate 2 %.
