| Abstract: | A new kind of vacuum vibration nozzle seed meter that is fit for seedling in green house was introduced.It applies working principles aerodynamics and vibration comprehensively. The paper theoretically studed the seed's forces and movement in the airflow of nozzle and analyzed the factors that influence suction force.By means of orthogonal test the parameters are tested and studied,and the optimum combination in production was analyzed. The machine possesses advantages of high rate of single seed and low rates of voiding and over sowing. It can also sow other seeds by substitution of the vacuum nozzle. |
