摘　　要：为了解决整秆式甘蔗收获机剥叶过程由于多根喂入和带尾部剥叶造成含杂率和折断率高的问题,设计了弹性齿滚筒式甘蔗剥叶装置,阐述了喂入、输出滚筒和剥叶滚筒的结构和剥叶原理,确定了主要部件的结构参数。通过四因素三水平正交试验研究剥叶元件弹性齿角度、剥叶滚筒中心距、剥叶滚筒转速和喂入、输出滚筒转速等4个因素对含杂率、茎秆折断率和断尾率的影响和最优参数组合,在此基础上进行综合剥叶试验。结果表明,最优参数组合为:剥叶元件弹性齿角度90°、剥叶滚筒中心距310 mm、剥叶滚筒转速700 r/min和喂入、输出滚筒转速150 r/min。甘蔗单根连续喂入319.19 kg,含杂率为1.56%、茎秆折断率为20.45%、断尾率为65.97%;3～5根连续喂入274.52 kg,相应的剥叶指标依次为2.38%、25.93%和75.59%。In order to solve the problem of high impurity rate and stalk broken rate existing in the leaf-stripping process of the whole stalk sugarcane combine harvester,the elastic dentation roller type leaf-stripping test device was designed.The main structure of feeding roller,output roller and leaf-stripping roller and the principle of leaf-stripping were introduced.The structure parameters of main parts were determined.The orthogonal experiments were conducted to study the influence between the following four factors,the installation angle of leaf-stripping component,the center distance between the top and bottom leaf-stripping rollers,rotate speed of leaf-stripping rollers and rotate speed of feeding and output rollers,and the following three indexes on leaf-stripping quality,impurity rate,stalk broken rate and top broken rate.The result showed that the optimal parameters were as following: the installation angle of leaf-stripping component was 90°,the center distance between the top and bottom leaf-stripping rollers was 310 mm,rotate speed of leaf-stripping rollers equaled 700 r/min and rotate speed of feeding and output rollers equaled 150 r/min.In the meantime,when the total weight of 319.19 kg sugarcane was fed continuously into the device in the way of single stalk,the impurity rate,stalk broken rate and top broken rate reached to 1.56%,20.45% and 65.97%.Otherwise,when the total weight of 274.52 kg sugarcane was fed continuously into the device in the way of three to five stalks simultaneously,the final result was 2.38%,25.93% and 75.59% respectively.
