Abstract

Concasseur autopropulsé pouvant fonctionner même sur sol meuble sans dégradation de ses caractéristiques de propulsion. Cet engin déplace automatiquement les pierres trop volumineuses qu'il ne peut concasser et concasse les pierres à mesure qu'il excave la surface du sol. Ce concasseur est pourvu d'une lame (17) fixée sur la partie avant d'un châssis de concasseur (10) présentant une unité d'entraînement (15) du type à chenilles, de sorte que la lame (17) puisse se déplacer verticalement, et une unité de concassage de pierres (20) fixée sur l'extrémité arrière du châssis de concasseur (10) par rapport à la direction de déplacement du concasseur, de sorte que l'unité de concassage de pierres (20) puisse être détachée et deplacée verticalement. Cette unité (20) possède un tambour rotatif (27) supporté en rotation sur les deux plateaux latéraux (21a, 21a) d'un organe de capot (21) qui s'ouvre vers la surface de sol et qui présente une pluralité de fleurets (29) sur sa surface circonférentielle; une unité de plateau répulsif (40), une unité de plateau de granulation (41) et une trieuse (42) qui sont écartées l'une de l'autre dans l'ordre mentionné dans le sens de rotation du tambour rotatif (27) et fixées à la surface interne de l'organe de capot (21), de manière à concasser les pierres de concert avec le tambour rotatif (27).
