Abstract

This study aimed to optimize a three-row air-suction Brassica chinensis precision metering device to improve the low seeding performance. ANSYS 17.0 Software was used to analyze the effect of different numbers of suction holes and different suction hole structures on the airflow field. It was found that a suction hole number of 60 was beneficial to the flow field stability and a conical hole structure was beneficial to the adsorption of seeds. Box-Behnken design experiments were carried out with negative pressure, rotational speed, and hole diameter as the experimental factors. The optimal parameter combination was achieved when the negative pressure was 3.96 kPa, the rotational speed of the seeding plate was 1.49 rad/s and the hole diameter was 1.10 mm. The qualification rate of inner, middle, and outer rings were 87.580%, 90.548%, and 90.117%, respectively, and the miss seeding rate of inner, middle, and outer rings were 10.915%, 7.139%, and 5.920%, respectively.

基于CFD-DEM耦合仿真的三排空气吸式芸苔精密计量装置优化

本研究旨在优化三排吸风式芸苔精密计量装置，以改善芸苔低播性能。采用ANSYS 17.0软件分析不同吸气孔数量和不同吸气孔结构对气流场的影响。结果表明，吸孔数为60有利于流场稳定性，锥孔结构有利于种子吸附。以负压、转速、孔径为试验因素，进行Box-Behnken设计试验。当负压为3.96 kPa，播种板转速为1.49 rad/s，孔直径为1.10 mm时，参数组合最优。内圈、中圈和外圈的合格率分别为87.580%、90.548%和90.117%，内圈、中圈和外圈的未播种率分别为10.915%、7.139%和5.920%。关键词:芸芥，计量装置，气流场，Box-Behnken设计DOI: 10.25165/ j.j ijabe.20231603.7812引用本文:孙晓平，李辉，齐晓东，冯德华，周建强，王永军，等。基于CFD-DEM耦合仿真的三排空气吸式芸苔精密计量装置优化农业与生物工程学报，2023;16(3): 130 - 142。
