| Abstract: |
| In order to obtain the optimal job parameter of potato digger with vibrating type of ladder shovel, according to the harvest mechanism of vibration and drag reduction, carried out the performance experiment through changing the 4 major operation parameters as machine speed, digging depth, digging shovel length and crank eccentricity these influenced performance indexes of the potato digger, with
the evaluating indicators as, losing rate, obvious rate and damage rate. Combining the orthogonal experiment research, has obtained the optimal combination for each job parameter, such as machine speed was 0.55 m·s-1, digging depth was 210 mm, length of the digging shovel was 205 mm, crank eccentricity was 6 mm by applying the overall rating method. According to the optimal combination of the job parameters to carry out the experiment and confirmation, the experimenta
l results showed that: The obvious rate was 97.6%, the damage rate was 3.9% and the losing rate was 3.5%, which could be met the the specification requirements of quality evaluation for the potato harvester. |
