| Abstract: |
| 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. |
