摘　　要： 甘蔗收割机的前进速度与根部切割器转速的匹配是确保收割机工作效率和切割质量的先决条件,同时也是确定甘蔗收割机各执行机构工作参数及其动力传动系统设计的重要理论依据之一。以华南农业大学自主研制的4ZZX-48型整秆式甘蔗收割机为研究对象,根据甘蔗的切割机理、圆盘切割器不漏割的条件和避免多刀切割的条件,分析收割机在收获过程中前进速度与切割器转速的相互匹配关系,并对甘蔗收割机的具体结构参数进行了计算和大田观察试验验证。结果表明:在保证根茬切割面质量(切割器转速大于500r/min)的条件下,收割机前进速度较快时,切割器的转速也应相应地较快,才能避免或减少多刀切割和漏割现象。 Matching of sugarcane harvester moving rate and basecutter rev is precondition of insuring harvester’s workefficiency and cutting-quality,and is also one of important theoretic basis which makes sure working parameters of harvest’s implementing organs and designs its power driving system. In this paper,the 4ZZX-48 whole-stalk sugarcane harvester,which has been developed by SCAU,is researching object. According as cutting mechanism of sugarcane,and condition of no-missing-cutting and avoiding many-times-cutting for disc basecutter,the matching relation is analyzed,and checked computations the relation with harvest’s structure parameters,and is observed harvesting test in field. The result indicate,under the condition of ensuring the cutting-quality of root-stubble （ basecutter rev is not less than 500 r /min）,many-times-cutting and no-missing-cutting are avoided or decreased only when the basecutter rev is increase along with the harvester moving rate increase.
