Abstract

In seeding operations, fermented seeds with weak surface energy tend to experience problems such as adhesion, seed leakage, and clogging on the seeder’s end. To improve seed distribution uniformity, a three-stage spiral seeding device with “seed filling, transport, and dispersing” functions was designed. Kinematic and dynamic models of fermented seeds under spiral conveying conditions were developed to analyze the motion and force characteristics of the seeds under various working states. A discrete element method (DEM) and multi-body dynamics (MBD) coupled simulation model was established, along with a comprehensive evaluation system for seed distribution uniformity and seeding effectiveness. The influence of spiral speed, pitch, and forward speed of the seeding operation on seed dispersion uniformity and operational efficiency was studied, and optimal structural and operational parameters for the spiral seeder were selected. A prototype of the spiral seeding device was fabricated, and field seeding tests were conducted. The results showed that when the seeder’s rotational speed was 12 r/min, the pitch was 63 mm, and the forward speed of seeder was 3.5 km/h, the seed distribution uniformity index reached 84.53%, with excellent seeding effectiveness and a comprehensive evaluation index of 92.26%. The field application demonstrated good performance, significantly improving both the operational reliability and efficiency of the spiral seeding device.
