Abstract：

    This research utilizes PIA image to analyze the counting and examining system. Detect the geometric physical characteristics of the lotus seeds. Go to the removing sprout test organization in initial stage, With different to removing sprout needle model and two kinds put the position, removing sprout test with statistical analysis knowing, the removing sprout which is taking off the membrane lotus should be divided into 10–12mm, 12–14mm, 14–16mm three grade in the initial stage process of proceeding. It means that the removing sprout lotus seeds should be put in second position and the removing rate relatively excellent efficiency will be shown for the needle of Concave-hole type. Develop semi-automatic lotus seeds removing sprout machine further in accordance with this result, The main techniques are to apply V-shaped base and lotus seeds characteristics of the short axis of the circular shape to let the long axis of the center line of the lotus seeds be with overlapping removing centerline automatically. Therefore, Conducting removing needle to remove operations will be able to remove the sprout of lotus seeds successfully. After that, using Ø3.0, Ø3.2, Ø3.4, Ø3.6mm and 7, 10, 30, 50, 80 cm/s for concave-hole diameter to remove sprout of lotus seeds needle and to remove sprout of lotus seeds needle speed. Then Matching 90°, 110°, 130°, 150° toper hole angle to conduct removing sprout of lotus seeds for experiment parameter. According to the statistical analysis, it shows that ellipse and round kinds removing rate is 98.67% and 99%. Can already popularize and application to the lotus seeds farmer.
