Abstract

In response to the serious issue of missed seeding of the seed-metering device caused by the small and gradually decreasing number of maize seeds in plot planting conditions, a precision seed-metering device for maize plots with pneumatic-seed spoon interactive was designed. The seed-metering device utilises the coupling interaction between the seed spoons and airflow to adjust the maize posture in the filling zone, achieving stable filling of the seed-metering device with a low population of seeds in the seed chamber. EDEM software is used to simulate and analyse the disturbance caused by three types of seed-metering discs and the average kinetic energy in the filling zone as the evaluation criterion. A test platform for seed-metering device of maize plot was constructed, with the qualified index, multiple index, and missing index as evaluation criteria. A full-factorial experiment was conducted with rotation speed of the seed-metering disc, air pressure, and types of seed-metering discs as factors, determining the optimal seed-metering disc for seeding performance. The results indicated that under conditions of low seed population in the seeding chamber, with air pressures ranging from −1.5 to −2.5 kPa and seed-metering disc speeds between 1.16 and 3.49 rad s−1, the seed-metering device with linear disturbance exhibited a multiple index of <6.25% and a missing index of <3.46%. Additionally, the qualified index consistently reached 90.29%. These evaluation criteria meet the standards, demonstrating effective seeding capabilities.

用于小区播种的气动播种勺交互式玉米种子精确计量装置的扰动分析和播种性能评估
针对小区播种条件下玉米种子数量少且逐渐减少,导致测种装置漏播的严重问题,设计了一种气动播种勺交互式玉米小区精密测种装置。该种子计量装置利用种子勺与气流之间的耦合互动来调整充种区内的玉米姿态,从而实现了在种子腔内种子数量较少的情况下稳定充种的种子计量装置。EDEM 软件用于模拟和分析三种类型的种子计量盘造成的干扰,并以充填区的平均动能作为评估标准。构建了玉米小区种子计量装置测试平台,以合格指数、多重指数和缺失指数作为评价标准。以测种盘转速、气压和测种盘类型为因素,进行了全因子试验,确定了播种性能最优的测种盘。结果表明,在播种室内种子数量较少的条件下,气压在 -1.5 至 -2.5 kPa 之间,排种盘转速在 1.16 至 3.49 rad s-1 之间,线性扰动排种器的多重指数为 <6.25%,缺失指数为 <3.46%。此外,合格指数始终达到 90.29%。这些评估标准均符合标准,显示了有效的播种能力。
