Abstract

Mécanisme de commande du herschage d'une haveuse pour minerais équipée d'éléments de havage placés au moins à une extrémité de la machine. Le mécanisme comprend au moins deux unités de commande dont l'une se trouve à proximité de chaque extrémité de la machine et dont l'une au moins comporte un mécanisme à engrenages pour commander un élément associé de commande du herschage, monté sur la machine et qui peut s'engrener avec une crémaillère portée par une structure de convoyeur ou reliée à cette dernière. Application à la commande du herschage d'une haveuse pour minerais.Harrowing control mechanism of an ore chopper equipped with cutting elements placed at least at one end of the machine. The mechanism comprises at least two control units, one of which is located near each end of the machine and at least one of which has a gear mechanism for controlling an associated Harrowing control element mounted on the machine and which can mesh with a rack carried by a conveyor structure or connected to the latter. Application to the control of the harrowing of a miner shredder.
