Abstract
In order to improve the uniformity and stability of seed delivery and meet the requirements of precision sowing operation, a kind of seed push wheel designed to mesh with the seed discharging disk was developed. The wheel underwent theoretical analysis and experimental optimization regarding parameters such as tooth profile, tooth count, and tooth height. Using a pneumatically inflated maize precision seed-metering device as the seeding carrier, a full-factorial experiment was conducted with operational speed and tooth height as the experimental variables, and qualification rate, reseeding rate, and leakage rate as the performance indicators. A multivariate quadratic regression model was established to assess the relationships between the factors and indicators. The results indicated that optimal seed guiding performance was achieved when the seed push wheel had 9 teeth, a tooth height of 5.2–6.2 mm, and an operational speed of 9.0–12.6 km/h. This study provides a theoretical foundation and data support for the development of precision seeding technology and corresponding seed guiding devices.
