摘要
对3个不同品种水稻芽种的几何尺寸、内摩擦角、休止角、滑动摩擦角、悬浮速度及密度、千粒重进行了测试。结果表明:水稻芽种三轴平均长7.0mm、宽5.0mm、高2.4mm;水稻芽种的内摩擦角、休止角、滑动摩擦角、悬浮速度随含水率的增大而增大。这些参数可为水稻芽种气吸排种器的设计提供依据。
The parameters of geometrical size, inner friction angle, caesural angle, suspension velocity, density, and 1000-grain weight of three species of rice budded seeds were tested. The results showed that the average geometrical size was 7.0 mm in length, 5.0 mm in width and 2.4 mm the height. Their inner friction angle, caesural angle and suspension velocity increase with the increase of moisture. These parameters could be used as the basis of designing seeding machines.
