摘　　要：传统离心撞击式剥叶装置采用根部喂入、剥叶辊筒与输入输出辊筒转向相同的剥叶方式,普遍存在着含杂率偏高、无法实现断尾的问题。为此,通过设计的甘蔗剥叶试验台进行了甘蔗尾部喂入、剥叶辊逆剥剥叶方式的试验研究,探索其剥叶效果,并分析了逆剥的剥叶和断尾机理。试验结果显示,逆剥方式在输入输出辊转速254 r/min,第1级剥叶辊(顺剥辊)转速1 152 r/min,第2级剥叶辊(逆剥辊)转速1 152 r/min时含杂率达到最低值0.7%,而断尾率达到100%。与顺剥方式进行对比试验,逆剥效果优势显著。The whole stalk sugarcane combine harvester needs independent leaf-stripping device. Because of the techno- logical process, the leaf-stripping device often adopt the mode that the sugarcane was fed from root and the direction of rotation of leaf-stripping roller is the same with feeding roller. This mode exist some problems of high impurity rate and that it can＇t break tails effectively. So this article present a new leaf-stripping mode that the sugarcane was fed from tail and the direction of rotation of leaf-stripping roller is inverse from the feeding roller. The leaf-stripping performance of this mode was tested by experiment. The experiment result shows that the impurity rate, tail broken rate reach 0.7 % and 100% when the rotate speed of feeding roller is 254r/min, the first leaf-stripping roller which the direction is the same with feeding roller is 1152 r/rain, and the second leaf-stripping roller which the direction is inverse from feeding roller is 1152r/rain.
