| Abstract: |
| In view of such problems as little soil covering and low burying quality faced by most of current machines, a new grape vine over-winter burying machine was developed. The key parts of the machine including digging components, soil transmission device, and decelerating and reversing device were designed, and an orthogonal field test was conducted with length of soil digger, linear velocity of vertical soil conveyer and linear velocity of horizontal soil conveyer as factors, and covering depth, covering width and throwing distance as indicators. On the basis of variance analysis of test results, the factors influencing working performance of the grape vine burying machine were analyzed, and the parameters of components were further optimized. The test results showed that, when the length of soil digger was 40 cm, the linear velocity of vertical soil conveyer was 1.4 m·s-1, and the linear velocity of horizontal soil conveyer was 1.65 m·s-1, the grape vine burying machine ran well and could meet the agronomic requirements. |
