摘　　要：设计了一种新型小麦粒播排种器,阐述了其结构形式及工作原理。针对排种器排种过程中充种区的复杂情况建立了数学模型,分析了充种过程的影响因素和具体数值关系。通过试验分析了真空室的真空度对排种器合格率的影响。A new-type wheat seed-metering device was designed, and its configuration and working principle were expounded. Based on the complex filling areain the seed-metering process, a mathematical model was set up, and then the influencing factors and concrete numerical rela- tions during the filling process were analyzed. At last the effect of the vacuum degree in the vacuum chamber on the qualification rate of metering device was studied through experiment.
