Abstract: No-tillage seeding is of great significance for adjusting and improving soil structure in Northeast China. The conventional no-tillage seeder faces several issues with its row cleaner, such as a low straw cleaning rate and a high working resistance. To address these problems, this paper utilizes the bionic design method and develops a bionic elastic row cleaner inspired by the motion behavior of mole excavation. The bionic structure includes bent teeth and a torsion spring for lateral throwing. The MBD–DEM coupled simulation technology is proposed as the experimental optimization method, and it analyzes the interactions between different row cleaners, straw, and soil. The results indicate that a bionic elastic row cleaner with curved teeth and a torsion spring for lateral throwing (BA-T) had a higher straw cleaning rate and total kinetic energy of straw. It also had lower working resistance. The field test results indicate that the BA-T improved the straw cleaning rate by 13.04% and reduced the working resistance by 39.24% compared to a flat row cleaner. This outcome also validates the accuracy of the simulation experiments. This study contributes to the design of new and efficient row cleaners suitable for maize straw mulching and no-tillage conditions, thereby promoting the adoption of conservation agriculture practices.
