Researchers developed a new corn seed planter with an inclined seed-metering device for high-speed operation. They used simulations to test different factors like rotation speed and inclination angle, finding that rotation speed had the biggest impact on seeding accuracy. Field tests showed the planter had a low missed seeding rate and high qualified seeding rate, meeting industry standards for precise corn sowing. The simulation model used was accurate and effective, providing support for future precision seeding equipment development.
