摘  要：
为解决现有往复式切割器收割龙须草的问题,拟对龙须草茎秆进行切割间隙、切割速度、切割刀片组合形式、切割茎秆部位、切割茎秆数量等因素进行了单因素试验,在单因素试验的基础上选取了正交试验的因素水平,完成了茎秆最大剪切力的正交试验,实验结果表明切割间隙和切割刀片组合形式对剪切力影响较大,切割速度对剪切力影响相对较小。最后通过选取斜齿刀-斜光刀组合模式与斜光刀-斜光刀传统刀片组合进行田间试验对比,结果表明斜齿刀-斜光刀组合的切断率提高了23%,刀片缠草率降低了94%,极大地提高了龙须草切割作业质量和作业效率。研究结果表明斜齿刀-斜光刀组合刀片用于龙须草收割是可行的。

摘  要：
In order to solve the problems of harvesting eulaliopsis binata by reciprocating cutter,the single factor test was carried out with the stem of eulaliopsis binata,which include the factors of cutting gap,cutting speed,cutting blade combination,the position and the number of stem cutting etc.Factors and levels of the orthogonal experiment were selected based on the single-factor test,then the stem maximum shear force orthogonal experiment was carried out.The results showed that the cutting gap and the cutting blade combination had greater effect on the shear force,while the cutting speed had less effect.Finally the field comparison tests were completed between the helical tooth-helical smoothing tool combination and the helical smoothing tool-helical smoothing tool traditional combination.The results showed that the helical tooth-helical smoothing tool combination increased 23% cuting rate and reduced 94% wrapping grass rate,which greatly improved the operation quality and efficiency of the eulaliopsis binata cutting.The results indicated that the helical tooth-helical smoothing tool combination for eulaliopsis binata harvest was feasible.
