Design and experiment of mechanical dustpan type-hole wheel corn seeder

Abstract

Using variable capacity seed filling technology, a dustpan type-hole wheel type corn seed discharging device with stopping plate was developed in order to enhance the mechanical hole wheel type corn seeder's seed discharging performance. By combining discrete element numerical simulation and methods that combine dynamics and kinematics theories. The structural parameters of the key components of the seeder were determined. Simultaneous corn hole sowing performance tests were done. The experimental findings indicated that the use of the dustpan type-hole resulted in qualified sowing rates of 97.2% for corn. The hole spacing rates for minimum qualification was 98.8%. Within the design parameters, changes in sowing operating parameters had a minor impact on the performance of the seeder. The bench performance test results demonstrate that the seeder's overall performance satisfies the criteria for agricultural planting.
