四行马铃薯杀秧机的设计

马铃薯收获前的杀秧工作是马铃薯高质量收获的重要环节,对提高马铃薯品质和收获效率具有很大的促进作用,而现有机型对于马铃薯杀秧效果并不理想,存在打碎长度合格率差、带薯率高、土壤在护罩上粘着严重等问题。为此,研究设计了一种新型高效的四行马铃薯杀秧机,通过理论分析确定了结构参数。田间试验结果表明:当作业速度为4.7km/h、甩刀轴转速为1 350r/min、垄上刀距垄台距离51mm时,试验指标打碎长度合格率为92.7%。此时杀秧机杀秧效果最好,满足马铃薯杀秧机作业质量要求。该研究为马铃薯杀秧过程存在的问题提供了解决方案,也为马铃薯杀秧机进一步的研究提供了参考。

Design and Experimental on Four-line Potato Haulm Cutter

Due to potato massive planting situation in current, it is very important to solve the problem of the use of potato haulm before the harvest. So that cutting seedlings before the potato harvest has a great role in promoting to improve the quality of potato and the potato harvest efficiency. Currently available machines for potato haulm cutting effect is not very ideal, and there are some problems such as poor breaking length qualified rate, high rate of tuber and soil severe adhesion in the shield. For the sake of solving these problems, this paper presented a four-line potato haulm cutter,the structural parameters were determined by theoretical analysis. The field test showed that when rotational speed of knife-cylinder was 1350r/min, forward speed was 4.7km/h and distance between knife on ridge and ground was 51mm, break length pass rate was 92%. At this point it has best effects that meet the quality requirements of potatoes haulm cutter. The study provided a solution during cutting the potato haulm and provided the reference for further research of potato haulm cutter.
