Seed singulator

摘要

A seed singulator for use with a vacuum disk having a seed face and a shoulder. The seed singulator has a first member and a second member supported by biasing members. The first member has upper lobes disposed at a radius of curvature slightly less than the outside radius of a row of apertures on a seed plane of the vacuum disk. The seed member has lower lobes disposed at a radius of curvature slightly greater than the inside radius than the row of apradius. The biasing members permit the lobes to move with the seed plane and the shoulder as the vacuum disk rotates thereby maintaining their position with respect to the apertures.

1. In combination, a seed singulator and a vacuum disk, the vacuum disk having a seed plane and a row of apertures at a radius R1 from the center of the id="REI-00014" date="20150317" vacuum id="REI-00014" disk, a radius R2 to the outside of the apertures, a radius R3 to the inside of the apertures, and a radius R4 to an annular shoulder of the vacuum disk, said singulator comprising:
a first member having upper lobes disposed at a radius of curvature slightly less than the radius R2and greater than the radius R1, said first member further having a surface biased radially toward the annular shoulder of the vacuum disk; a second member having lower lobes disposed at a radius of curvature slightly greater than the radius R3and less than the radius R1; said upper and lower lobes having substantially co-planar surfaces biased axially against the seed plane of the vacuum disk.
