AI Technical Summary
Technical Problem
Existing precision seeders for corn plots suffer from problems such as limited variety, poor seed filling effect, and high rate of missed seed filling.
Method used
A centrifugal seeding-dual-hole interactive precision seed metering device for corn plots is adopted. The centrifugal blades disperse the corn seeds, and the seeds are moved in an orderly manner and filled with seeds by combining pneumatic force and negative pressure adsorption through the holes. The traditional center-driven method is improved by a dual-drive structure.
Benefits of technology
It improved the filling effect of corn seeds, ensured precise seeding of single seeds, reduced the missed filling rate, and improved the efficiency of mechanized sowing.
