Abstract

L'invention concerne un appareil de tamisage (1) pour tamiser un matériau particulaire. Cet appareil comprend: un châssis de base (11); un convoyeur de levage (12); un support de convoyeur (13) fixé de manière réglable sur le châssis de base (11) et disposé de manière à pouvoir déplacer le convoyeur (12), généralement dans le sens de la longueur, afin d'ajuster la position d'une extrémité supérieure (16) de l'extrémité (16) du convoyeur; un sous-châssis (18) fixé de manière réglable, et de façon à pouvoir pivoter, sur le châssis de base (11) via un pivot (20) et supportant un tamis vibratoire (17) prévu pour recevoir le matériau tombant par gravité depuis l'extrémité de décharge supérieure (16) du convoyeur (12). Ce sous-châssis peut être réglé autour du pivot afin de régler l'orientation du tamis. L'appareil comprend, en outre, des moyens de décharge (23) pour décharger les parties tamisées séparées du matériau ainsi qu'un élément de liaison (19, 22) entre le sous-châssis (18) et le support (13) comportant un raccordement direct pivotant (20) entre ces derniers, ce qui permet d'ajuster simultanément le sous-châssis dans le sens de la longueur. Le convoyeur de levage (12) et le support de convoyeur (13) comprennent une partie principale (12a, 13a) s'étendant depuis un poste de chargement (14), et une partie d'extrémité supérieure (12b, 13b) qui comprend l'extrémité de décharge (16) du convoyeur. Ces parties sont raccordées, de manière articulée, entre elles pour faire passer l'appareil en mode opérationnel, dans lequel la partie d'extrémité forme un prolongement de la partie principale, et en mode de transport dans lequel l'extrémité est pivotée vers le bas par rapport à la partie principale, ce qui réduit la hauteur de transport de l'extrémité de décharge du convoyeur.
