Structural Analysis and Design of the Combined Studded Feed Roller Seed Metering Device

摘要

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,In order to enhance performance of the combined studded feed roller when sowing the big seeds,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,which combining the size of crop seeds, provided theoretical direction for the further study and optimum structure on the combined studded feed roller seed metering device of no-tillage drill for the future.
