摘　　要：为了确定两段螺旋式扶起机构的结构参数,运用虚拟技术对该机构和甘蔗扶起过程进行了运动学仿真,设计了两段螺旋式扶起机构样机,在高速摄影的环境下进行了甘蔗扶起性能试验,获得扶起机构对甘蔗的作用及影响规律。结果表明:扶起机构适用于侧向倒伏角为45°～165°的甘蔗;速比为0.59,拣拾段安装角为5°,输送段安装角为60°时,扶起甘蔗效果最好。Based on dynamic simulation, two sections spiral sugarcanes lifter was designed and a sample machine was made. The effect rules of the two sections spiral sugarcane lifter were got through experimental test associated with the application of high-frequency photograph technology. The experiment results showed that, the two sections spiral sugarcane lifter worked well with lodge-angle of 45° -165°. Furthermore, the lifter worked best when the parameter of movement was 0.59, and the picking angle of setting was 5°, and the transportation angle of setting was 60°.
