    摘要:

    采用高速攝像技術(shù)拍攝了型孔式水稻排種輪的充種過程，分析了充種區(qū)內(nèi)稻種的流動(dòng)規(guī)律、充種姿態(tài)以及充種趨勢。高速攝像表明：稻種在充種區(qū)內(nèi)主要是沿著限種板一側(cè)向下流動(dòng)，流動(dòng)后稻種呈豎立或斜立姿態(tài)；在稻種充入型孔的過程中，稻種首先以豎立或斜立姿態(tài)充入到排種輪型孔中，其余稻種以平躺姿態(tài)填充到型孔上部；91.1％的稻種集中在第2充種區(qū)內(nèi)完成最終的充種過程，因此充分利用第2充種區(qū)可以提高型孔式排種輪的充種性能。

    Abstract:

    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. 
