| Abstract: | Based on working principle of slant disc pneumatic metering device,the moving process of a single seed on metering disc was analyzed and the movement stage was determined.Seed movement during metering procedure was investigated and mathematic model describing seed movement was developed.A simulation of seeds filling procedure within the metering device was carried out with computer program MATLAB.The results showed that the influence factors of seed movement were slant angle of the disc,the friction coefficient of seed with the metering disc.For different kinds of seeds with different physical characteristics,the optimum working performance of the metering device could be obtained only by selecting different combination of parameters of the metering device. |
