    Design and test on leaf-stripping device of sugarcane harvester by a vertical clamping-conveying channel

      摘要
    • 摘要:
      目的  探讨甘蔗立式夹持输送剥叶技术在整秆式收割机中的可行性，解决现有整秆式甘蔗联合收割机甘蔗通道长、作业效率低的问题。
      方法  以4ZZX-48型甘蔗收割机为作业平台，在输送通道上设计立式剥叶装置。通过收获试验，分析了夹持输送链轮转速(n1)、剥叶辊筒角度(β)、剥叶辊筒转速(n2)和甘蔗喂入率(q)等因素对甘蔗立式夹持输送剥叶性能的影响。
      结果  n1和n2对剥叶性能有显著影响，各因素对剥叶性能的影响依次为n1>n2>q>β。n1为60 r/min、β为30°、n2为360 r/min、q为7.5 kg/s时，甘蔗叶片剥净率为76.6%，剥叶性能达到最优。曲线回归分析表明，剥叶辊n2/n1与剥净率之间存在着二次多项式关系，n2/n1在5~6之间时，剥净率约77%，达到试验最优值。
      结论  基于甘蔗立式夹持输送剥叶技术的收割机具有可行性，本研究结果对研发新型整秆式甘蔗收割机有一定参考价值。

       

      Abstract:
      Objective  To explore the feasibility of sugarcane vertical clamping-conveying technology for the whole stalk harvester, and provide a technical support for solving the problem of long sugarcane channel and low working efficiency of the existing stalk-type sugarcane combine harvester.
      Method  A kind of vertical stripper was designed in a clamping-conveying channel for 4ZZX-48 sugarcane harvester . A harvesting test of this device was conducted in field. The influence factors of leaf stripping effect were analyzed, including the rotation rate of conveyor chain sprocket(n1), the installation angle of leaf stripping roller(β), the rotation rate of leaf stripping roller(n2) and sugarcane feeding speed(q)
      Result  The values of n1 and n2 had significant impact on leaf stripping effect. The ranking of influence was n1>n2>q>β. When n1 was 60 r/min , n2 was 360 r/min , β was 30° and q was 7.5 kg/s, the machine got the best stripping effect and leaf stripping rate was 76.6%. The results of curve regression analysis showed that there was a quadratic polynomial relation between clearing rate and the ratio of n2 to n1. When the value of n2/n1 ranged from 5 to 6, clearing rate reached the maximum of around 77%.
      Cluclusion  This harvester, based on sugarcane vertical clamping-conveying and stripping technology, is feasible and has certain reference value for research and development of a new whole stalk sugarcane harvester.
