| In order to meet the agronomic technical requirements of whole film double furrow sowing on dry-land, an electric corn precision seeder was designed. An orthogonal test was conducted using height of the hill-drop wheel's capacity of seed, speed of hill-drop wheel, and length of flange as the parameters, rate of no-seed holes and rate of single-seed as the indicators. Then the test results were used to do variance analyses, concluding the factors influencing working performance of the electric corn precision seeder, and optimizing further the parameters of components. The test results showed that when the height of hill-drop wheel's capacity of seed was 130 mm, the speed of hill-drop wheel was 0.85 m·s-1, and the length of flange was 65 mm, the electric corn precision seeder ran well and could meet the agronomic requirement. |
