    • A seed singulator (900) for use with a vacuum disk (200) having a seed face (204) and a shoulder (230). The seed singulat (900) has a first member (906) and a second member supported by biasing members (926.932). The first member (906) has upper lo (908,910.912) disposed at a radius of curvature slightly less than the outside radius of a row of apertures (208,508) on a seed plane o the vacuum disk (200). The seed member has lower lobes (914.916) disposed at a radius of curvature slightly greater than the inside radius than the row of apertures (208,508). The biasing members (926,932) permit the lobes (908.910,912,914.916) to move with th seed plane (222.522) and the shoulder (230) as the vacuum disk (200) rotates thereby maintaining their position with respect to the apertures (208,508).
    • 一种与具有种子面(204)和肩部(230)的真空盘(200)一起使用的种子分选机(900)。 种子单体(900)具有第一构件(906)和由偏置构件(926.932)支撑的第二构件。 第一构件(906)具有设置在稍微小于真空盘(200)的种子平面上的一排孔(208,508)的外半径的曲率半径的上部凸缘(908,910.912)。 种子构件具有设置在比一排孔(208,508)稍大于内半径的曲率半径处的下凸角(914.916)。 当真空盘(200)旋转时,偏置构件(926,932)允许叶片(908.910,912,914.916)随晶种平面(222.522)和肩部(230)移动,从而保持它们相对于孔(208,508)的位置。
