摘　　要：设计了一种由锥形螺旋滚筒和拨指链组成的组合式扶起装置,并在土槽中进行了试验研究。以扶起合格率为试验指标,对甘蔗倒伏状态、螺旋滚筒转速、甘蔗与滚筒中心距离和前进速度为因素进行正交试验。在得出优化组合后,再分别进行滚筒轴线与地面夹角、滚筒叶片螺距和滚筒转速等因素的单因素试验,以及滚筒转速和前进速度的双因素试验。通过高速摄影分析了扶起过程。试验结果表明,在最优参数组合下,组合式扶起装置对严重倒伏甘蔗的扶起合格率达到90%。In order to lift severely lodging sugarcane in harvesting,the combined-lifter composed of spiral roller and chain-lifter was designed,which was experimented on the vehicle of soil.The orthogonal experiments were conducted to study the following factors： the state,rotational speed of spiral roller,distance between sugarcane and spiral roller center and advancing velocity.According to the best combination of orthogonal test,the single experiments were conducted to study the following factors： the angle between the cylinder axis and ground,the blade pitch of helical spiral roller and rotational speed of spiral roller.The double experiments were conducted with the rotational speed and advancing velocity. High-speed photography experiments were conducted to analyze the process of lifting.In the optimal parameters,the results showed that eligible rate of lifting was up to 90% by the combined-lifter.
