Abstract


The seed-metering device as the core component of planter is the main factors to determine the characteristics and performance of planter. The Combined Studded Feed Roller Seed Metering Device is a new metering device used for sowing in lines of no-tillage planter, which has many advantages such as good universality and convenient adjustment of application rate, and hign precision of sowing minimum–seeding especially for the small seeds (such as Alfalfa,Millet and Rapeseed ) .In this paper ,the size of Big Studded Feed Roller Nail tooth gap of The Combined Studded Feed Roller Seed Metering Device had been analyzed in theory from the structure and the work principle,which combining the size of crop seeds. It determined the primary Structural parameters which are the impact of the Combined Studded Feed Roller Seed Metering Device: the number , thickness and shape of the big studded feed roller teeth.This article has improved designed the big studded feed roller on the basis of analysis result. The working performance of metering was tested using the ( ( )) table arranged experimentation gathered scheme. There are four seeds used in the experimentation:corn(Dongling white),corn(zhedan 7), sunflower and soybean.The results indicate,we gained the optimization structure parameter of the Combined Studded Feed Roller Seed Metering Device. It also can reduce the thickness of seed tugged by the studded feed roller seed metering device and effect on work performance of metering.
