| Abstract: |
| In northeast ridge-zone of China, the temperature is low, and wind erosion and spring drought occurred seriously. Maize planting proposed higher requirements for the performance of no-till planter. In order to ensure the stability of sowing depth and improve sowing quality, the transfer function of new profile loading mechanism was established by analyzing the time of sowing depth and spring deformation of no-tillage sowing with two different loading mechanisms. The spring deformation variable mean value and variance coefficient are 0.26 cm and 38.5%, respectively, when the working speed is 5 km·h-1, and the damping ratio of the system is less than 0.62. Response time and maximum overshoot were reduced by 18% and 32%, respectively. The result is better than that of original profile loading system, which is favorable to the trench depth stability of no-till planter. |
