Abstract

L'invention concerne un appareil d'épandage, en particulier destiné aux véhicules des services de déneigement, pour l'épandage d'un produit à épandre. Cet appareil comprend une trémie de produit à épandre, une unité d'épandage et un trajet de convoyage de produit à épandre situé entre la trémie et l'unité d'épandage. L'unité d'épandage possède un plateau rotatif d'épandage (3) et une chambre centrale de mélange (4) dans laquelle débouche le trajet de convoyage du produit à épandre. La chambre de mélange (4) comprend un fond rotatif mélangeur (5) et une cloison (6) non rotative comportant une paroi latérale (7) qui s'étend autour de l'axe de rotation (1) du fond mélangeur et une pièce supérieure de fermeture (8). La paroi latérale (7) présente une ouverture de sortie (9). La pièce supérieure de fermeture (8), au moins à proximité de la paroi latérale (7), offre une hauteur variable par rapport au fond mélangeur (5) dans la direction de la circonférence.
