| Abstract: | A new kind of vacuum-vibration seeder fit for seedling in green house is introduced. The theory of seed suction performance of the seeder was analyzed and the mathematical model under the effect of airflow was obtained. The result of experiments is basically in accordance with the mathematical model. The relationship between the height of sucking seeds and the vacuum in the sucking mouth was given. And at the certain vacuum the relationship between the height of sucking seeds and the sucking nozzle diameter could be gained. |
