| 中文摘要: |
| 目前国内应用较为普遍的马铃薯挖掘机将薯块挖掘条铺后需人工捡拾，工作效率低、劳动强度大。针对以上问题，设计了一种与30 kW拖拉机配套的小型马铃薯捡拾机。该机主要由捡拾装置、薯土分离装置、薯块升运装置、薯块收集装置等几部分组成，制作了样机并进行了田间试验。试验表明：该机薯土分离彻底，机组纯工作小时生产率为0.35～0.38 hm2·h-1，平均伤薯率为4.4%，漏薯率为2.1%，含杂率为6.3%。 |
| 英文摘要: |
| Currently, the domestic potato excavator can only excavate the potatoes, but it can’t pick them up, which requires additional human labor, resulting in low working efficiency and high labor intensity. To address these problems, this paper discusses a design of a small potato pickup machine which is compatible with the 30 kw tractor. This machine is mainly composed of pickup device, potato soil separation device, potato elevator device and potato collection device. The prototype has been finished and the test was carried out in the field. The test showed that it could separate potato and soil thoroughly. The pure hour productivity was 0.35～0.38 hm2·h-1, the average damaged potatoes rate was 4.4%, the potato leakage rate was 2.1%, and the impurity rate was 6.3%, demonstrating that it has a broad application prospect. |
