| 摘 要： | 为适应甘肃省马铃薯种植地块小、坡地多的现状，提高马铃薯机械化收获水平，通过对各关键作业部件进行理论分析与设计选型，研制出了一种携有偏心摇臂结构振动挖掘装置，挖掘深度可调节且与手扶拖拉机相配套的4UM-640型振动式马铃薯挖掘机。田间试验表明：该挖掘机收获作业时掘薯、输运顺畅，减阻碎土、土薯分离效果明显，伤薯率为3.6%，损失率为4.1%，明薯率为97.1%，达到了马铃薯机械化收获的相关技术要求。

| Abstract: | In order to suit the status quo of small potato planting plots and more slope land in Gansu Province, improve the machinery harvesting level of potato, through the theoretical analysis, design and selection for each key machine component, have designed out a 4UM-640 vibrating potato digger which held a eccentric swing arm structure and vibration digging installation, the excavating depth can be adjusted and matched with the walking tractor. The field experiment has showed that: When this potato digger was operated, digging potato, smoothly transport, drag reduction and broken soil with evident effect to separate the soil and potato, the potato damage rate was 3.6%, the loss rate was 4.1%, the distinct rate was 97.1%, has reached the relative technical requirements for the potato machinery harvest. |
