“In response to the problems of poor particle spacing uniformity and high energy loss caused by severe seed collisions during high-speed operation of corn seeders, researchers have designed a positive pressure airflow injection assisted seed delivery and guidance device based on the Venturi effect. The structural parameters are optimized using EDEM Fluent coupling simulation, and the airflow assistance increases the horizontal velocity of the seed outlet by 78.5%, significantly reducing motion randomness, providing a new solution for the development of high-speed precision seeding equipment.”
