摘　　要：采用高速摄像技术拍摄了型孔式水稻排种轮的充种过程,分析了充种区内稻种的流动规律、充种姿态以及充种趋势。高速摄像表明:稻种在充种区内主要是沿着限种板一侧向下流动,流动后稻种呈竖立或斜立姿态;在稻种充入型孔的过程中,稻种首先以竖立或斜立姿态充入到排种轮型孔中,其余稻种以平躺姿态填充到型孔上部;91.1%的稻种集中在第2充种区内完成最终的充种过程,因此充分利用第2充种区可以提高型孔式排种轮的充种性能。High-speed photography technology was used to analyse the seeds flowing rule,feeding-seed posture and the feeding trend in feeding process for the cell wheel of the precision rice hill-drop drilling machine.The high-speed photographs showed that seeds mainly flow down from the control board with erect or oblique posture.In the feeding process,most seeds feed into the bottom of the cell in erect or oblique posture and other seeds feed to the upper in flat posture.Totally 91.1% seeds finish the feeding process in the second feeding-room. Therefore, the optimal design of the second feeding-room can improve the performance of the feeding process.
