Introduction The design of the maize metering device involves centrifugal variable diameter pneumatic and cleaning mechanisms, aiming to enhance performance power efficiency devices. Leveraging impact changes in guidance positioning airflow, we optimize hole insert, seeding plate, seed limit board, integrated front shell. This optimization facilitates adjustment both quantity posture filling. As a result, seeds can form uniform flow within annular cavity, reducing wind pressure necessary for regular operation decreasing consumption. Methods A quadratic regression orthogonal rotation combination experiment is conducted using self-made bench, considering ground speed, pressure, rate as factors. Furthermore, comparative involving novel variable-diameter type device. Results results indicate optimal when speed 13.2 km/h, 1.2 kPa, feeding 25 seeds/s. Under these conditions, quality feed index reaches 95.20%, multi-index 3.87%, miss 0.93%. Findings reveal that developed achieved exceeding 93.00% across varying speeds 12~18 aligning with production requirements. Moreover, actual consumption Type B C about 85.00% 98.00% lower than A, standing at only 32.90 W 18 km/h. COP 86 times 12 B, respectively, meeting demands efficient Discussion In comparison traditional structural parameter methods device, this study helpful sustainable development industry reduce environmental pollution.

This study proposed a high-speed precision dual-chamber maize metering device for the dense planting pattern with standard ridge promoted in China. Through theoretical analysis of sowing process, parameters key components have been designed. The is capable two rows single pass seeding. effect operating speed and negative pressure on seed quality was investigated. A camera used to capture trajectory at different speeds, it found that intra-row shifts were caused by collisions mouth guide tube rotation as fell. Employing two-factor, five-level orthogonal test, Investigated optimal device. Response surface showed optimum achieved 14.2 km/h 13.5 kPa. Validation tests qualified rate 97.93%, coefficient variation 8.97% this method. Additionally, an energy consumption indicated reduction approximately 32% compared conventional air suction devices large ridges same area farmland. provides insights reducing seeding contributing sustainable development agricultural resources.

In response to the poor cleaning effect of brush-type soybean seeder, a lightweight mechanism seeder was optimized and designed. We proposed progressive seed-cleaning method. Firstly, mechanical analysis conducted on seeding process prevent excessive clearing individual seeds initially filled into orifices by brush. A formula for expressing force exerted brush stabilizing in orifice derived. Secondly, an principle performed, theoretical calculations were carried out curves within x-y plane along direction z-axis. The determined. Factors affecting efficiency analyzed, including plate’s speed, initial angle brush, distance between plate. Based Box–Behnken central composite design theory, using tray’s rotational tray as experimental factors, orthogonal experiments with leakage rate over-cleaning indicators evaluation, working parameters optimized. Validation showed that plate speed 29 rpm, 54°, 11 mm, results follows: skip-seeding 1.23% over-seeding 0.66%, indicating significant improvement performance. comparative experiment non-progressive brushes, test reduced more than 1% 0.5%.
