Parameter Optimization and Performance Testing of a Variable-capacity Spoon-type Precision Hill Seeder for Strip-intercropping of Soybean and Maize
摘要
Abstract
This study addressed the lack of specialized precision seeding machinery for soybean-maize strip intercropping in the Or-dos region of Inner Mongolia by proposing a variable-capacity spoon-type precision hill seeder,combined with three suitable strip in-tercropping patterns.Mechanical models were established for the seed filling,spoon cleaning,and bridge cleaning stages,and the theoretical operating angular velocity range of the seeder was determined as 0～6.6 rad/s.Using the EDEM software,single-factor and response surface simulations were conducted to optimize three key parameters,i.e.,the angular velocity,the spoon inclination angle,and the bridge groove length.The results showed that the optimal seeding parameters for maize were an angular velocity of 4.7 rad/s,a spoon inclination angle of 71.3°,and a bridge groove length of 15 mm,for soybean,the optimal parameters were 5.5 rad/s,78.8°,and 10 mm,respectively.Field experiments further validated the simulation outcomes,which showed that the soy-bean achieved a qualified seeding rate of 89.2%～90.2%,a missed seeding rate of 2.5%～2.9%,and a reseeding rate of 2.9%～3.8%,the maize achieved a qualified seeding rate of 93.8%～94.4%,a missed seeding rate of 2.96%～3.01%,and a reseeding rate of 2.6%～2.8%.The discrepancy between the simulation and field results was minimal,meeting agronomic requirements.Overall,the seeder is structurally simple,cost-effective,and suitable for large-scale promotion of mechanized soybean-maize strip intercrop-ping in Ordos and similar regions.关键词
