为了优化推倒式甘蔗收获机的工作参数,设计了甘蔗扶起效果试验装置。通过正交及单因素试验,探明了甘蔗扶起过程的影响因素。结果表明：扶蔗器转速对甘蔗扶起效果影响最大,其次是机车前进速度。扶蔗器转速与机车前进速度的交互作用对扶起姿态角有显著性影响。在扶蔗器转速为120r/min、输送段安装角为50°、拣拾段安装角为5°和前进速度为0.21m/s参数组合下,对侧偏角在45°～135°范围内倒伏甘蔗能够有效平稳扶起。扶起姿态角范围为50.68°～68.87°,能满足机器作业要求。 To optimize operational parameters of push-over type sugarcane harvester, a test device of sugarcane lifter was designed. The main influencing factors for sugarcane lifting were disclosed through orthogonal experiment and single factor experiment. The results showed that the effect of rotating speed of spiral support device on lifting efficiency was significant, followed by that of forward speed of the lifter. Furthermore, the interaction of the revolving and forward speeds on lifting attitude angle was dramatically. The optimal parameters were as followed： the harvester rotation was 120 r/min, forward speed of the lifter was 0.21 m/s, setting angle of conveying section was 50°, setting angle of picking section was 5°. Under these conditions, the lifting quality was best with 45°-135°of slide angle and 50.68° to 68.87° of lifting attitude angle, which met the need of sugarcane harvester operation.
