Title (EN) DEVICE FOR SINGULATING PARTICLES INCLUDING A RAPID, SINGLE KERNEL GRAIN CHARACTERIZATION SYSTEM
(FR) DISPOSITIF SERVANT A ISOLER DES PARTICULES COMPRENANT UN SYSTEME DE CARACTERISATION RAPIDE DE GRAINES INDIVIDUELLES
Abstract:
(EN) 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 (2) having an inner surface cut with a spiral groove (6) for orienting ellipsoid-shaped particles and advancing them to the location of pickup orifices (8) within the drum (2). A vacuum valve (15) alternately subjects the orifices (8) to vacuum and ambient pressure (13) for picking up the individual particles and releasing them to the desired point of delivery (21).
(FR) Un dispositif d'alimentation isole, dirige et amène des graines et d'autres matières particulaires présentant des surfaces comparativement unies jusqu'à un lieu désiré. Le dispositif comprend un tambour (2) à rotation horizontale dont la surface interne est pourvue d'une rainure en spirale (6) destinée à orienter des particules ellipsoïdales et à les faire avancer jusqu'à des orifices d'aspiration (8) à l'intérieur du tambour (2). Une soupape à vide (15) soumet les orifices (8) alternativement au vide et à la pression ambiante (13) afin de saisir des particules individuelles et de les relâcher à l'emplacement de réception désiré.
