The Study of Computer Simulation on Seed Spacing Distribution of Percision Planters

The study of seed spacing disltribution of precision drilling is an important component of precision drilling theory. This paper mainly discusses the seed-metering device in which a metering plate revolves on horizontal oxis. The study of this suitable both for mechamical and for penumatic seed-metering devices which are widely used inside and outside the country. Based on the analysis of seed spacing error formation,the working process of the precision planter is divided into two step-seed filling and seed dropping. A dynamic seed spacing distribution model on different parameters is established by mean of mathematical statistics, mathematical equation and precision drilling theory .We also make computer simulation for the seed spacing distribution of the crops such as corn , soybean ect.The study of this paper offers a new way to improve the design method of the precision planter.
