The crop divider is a key component of sugarcane chopper harvester, which has an important effect on the lifting of lodged canes. In this study, it is important to improve the performance of crop dividers, especially when there is severe lodging of the canes. Liugong 4GQ-180 sugarcane chopper harvester was employed to evaluate the lifting performance of crop dividers. Firstly, a large number of canes at different levels of lodging were observed and the lodging angles and side angles were recorded. Further, the single factor test was conducted to investigate the effect of the lodging angles and side angles on the crop divider performance. The results showed that the lifting height is directly proportional to the lodging angle; however, the lifting height of sugarcane increased initially and then decreased with the increasing side angles. The results of two-way ANOVA revealed that the effect of the lodging angle was more significant than the side angle. In addition, the high-speed photography was analyzed to observe the lifting process of lodged canes. However, in other lodging conditions (α > 75°, or β < 15°, or β > 165°), the lifting effect was still not satisfactory. When cane stalks intertwined seriously, uprooting problems would occur. Therefore, it was necessary to improve the performance of crop dividers in harvesting canes with various levels of lodging.

作物分频器的性能与收获甘蔗的比较

作物分隔器是甘蔗斩波收割机的关键组件，对举起残存的甘蔗有重要影响。在这项研究中，重要的是提高农作物分隔器的性能，特别是当藤条严重倒伏时。柳工4GQ-180型甘蔗切碎机收割机用于评价分切机的举升性能。首先，观察到大量的甘蔗处于不同的倒伏水平，并记录了倒伏角度和侧角。此外，进行了单因素测试，以研究倒伏角和侧角对农作物分割器性能的影响。结果表明，提升高度与倒伏角成正比。然而，甘蔗的举升高度开始增加，然后随着侧角的增加而降低。双向方差分析的结果表明，倒角的影响比侧角更显着。此外，还对高速摄影进行了分析，以观察倒伏的手杖的抬起过程。但是，在其他住宿条件下（α  > 75°，或β  <15°，或β  > 165°），提升效果仍不令人满意。当甘蔗茎严重缠绕在一起时，就会发生连根拔起的问题。因此，有必要在具有不同倒伏水平的收割甘蔗中提高作物分隔器的性能。
