| 针对马铃薯挖掘机输送分离部件伤薯率高和土薯分离率低的问题，采用正交试验对抖动轮振幅、升运链线速度与升运链倾角进行探讨研究。在利用试验结果的基础上做出方差分析，得出影响输送分离部件工作性能的因素主次，进一步优化组合部件参数，设计出适应性强、工作可靠的马铃薯挖掘机。实验结果表明:抖动轮振幅为10 mm、升运链线速度为1.3 m·s-1、升运链倾角为21°时马铃薯挖掘机土壤分离效果良好，伤薯率≤4%。 |

| Aim at the problem of high injury potato and lower soil potato separation rate by the delivery separate components in potato digger, has discussed and researched the dithering wheel's amplitude, lifting chain's linear velocity and lifting chain's dip angle by adopting the orthogonal experiment. On the basis of the test results, the variance analysis was processed, has obtained the main and second factors effected the working performances of delivery separate components, further optimized and associated the component's parameters, and designed out the high adaptable and reliable potato digger. The experimental result shown that: The soil and potato separation effect was well and injury potato rate was less than 4%, when the dithering wheel's amplitude was 10 mm, the lifting chain's linear velocity was 1.3 m·s-1 and the lifting chain's dip angle was 21°. |
