摘要
为研究不同玉米、豆粕含量对粉状配合饲料摩擦特性影响。利用直剪仪、斜面仪、休止角测定装置,对不同配比的粉状配合饲料的内摩擦角、滑动摩擦角和休止角进行了测定。测定结果表明:粉状配合饲料的内摩擦角都随玉米含量的增大而减小、随豆粕含量的增加而增大;滑动摩擦角随玉米含量的增加而增大、豆粕含量的减少而增大;玉米、豆粕含量对休止角影响差异显著。
In order to study the influence of different corn and soybean meal contents on the lriction characteristics of mash feed, parameters as internal friction angle, sliding friction angle, repose angle of different containment has been measured by means of direct shear apparatus, self-made bevel instrument and the angle of repose measuring device. The results show： The internal friction angle of mash feed decreases with the increase of the content of corn, and increases with the increase of the content of soybean meal. And sliding friction angle increases with the increase of the content of corn, with the decrease of the content of soybean meal. The content of corn and soybean meal had signifi- cant difference on the repose angle.
