Abstract

L'invention concerne un rotor (1) d'un pulvérisateur comprenant: un arbre tournant (2) raccordé à un appareil d'entraînement; deux disques de coupe externes en forme de plaques (3) disposés sur l'arbre tournant de manière espacée; et de multiples arbres à palettes (5) supportés sur les deux disques de coupe externes le long de la circonférence des disques de coupe externes, chacun étant raccordé à de multiples palettes (7). De multiples parties d'ouverture (32) sont disposées sur la circonférence de chaque disque de coupe externe. Chaque partie d'ouverture est dotée d'une partie de serrage (322) et d'une partie d'évacuation et d'admission (321) pour l'entrée ou la sortie de chaque arbre à palettes. Le rotor d'un pulvérisateur est également doté d'un manchon de verrouillage (4). Le manchon de verrouillage est doté d'une partie de verrouillage (44) montée sur la partie de serrage de la partie d'ouverture et d'une partie de joint axiale (43) permettant à chaque arbre à palettes d'entrer de façon axiale et de limiter la sortie radiale de l'arbre à palettes. La forme de la partie de serrage de la partie d'ouverture correspond à la forme du manchon de blocage et permet à la partie de blocage d'entrer de façon axiale et de limiter la sortie radiale de la partie de blocage de la partie d'évacuation et d'admission de la partie d'ouverture. Le rotor d'un pulvérisateur peut être rapidement assemblé et remplacé de manière groupée.
