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. 
