| Abstract: |
| 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°. |
