摘要
通过对分种盘排种性能的单因素试验,初步确定了排种性能的主要影响因素。为进一步验证所选因素对试验指标的影响程度,进行了分种盘排种性能的正交试验研究,通过对试验结果的极差和方差分析,得到了试验结果的最优组合,为分种盘结构参数设计和工作参数的选择提供了理论基础。
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.
