Device for singulating particles |
摘要 |
A feeding device singulates, orients, and delivers seeds and other comparatively smooth-surfaced particulate material to a desired destination. The device comprises a horizontal rotating drum having an inner surface cut with a spiral groove for orienting ellipsoid-shaped particles and advancing them to the location of pickup orifices within the drum. A vacuum valve alternately subjects the orifices to vacuum and ambient pressure for picking up the individual particles and releasing them to the desired point of delivery.
