Optimization design and experiment of key components of mountain pendulum-lever cam type hole seeders based on DEM-MBD coupling simulation.

As can be seen from Fig 12b and 12e , as the angle of the movable pendulum-lever increased from 70° to 110°, the miss seeding rate of corn and soybean showed a trend of decreasing and then increasing, and the miss seeding rate reached the lowest value of 4.52% and 4.55%, respectively, at the angle of the movable pendulum-lever of 100°, with a decrease of 5.4% and 6.44%, respectively, compared with that at the angle of the movable pendulum-lever of 70°.
