Abstract
La présente invention concerne une tête de coupe pour haveuse, comprenant un tambour délimitant un axe de tambour, un plan de tambour s'étendant perpendiculairement à l'axe de tambour. La tête de coupe comprend une pluralité d'ensembles trépans fixés à une surface extérieure du tambour à proximité d'une première extrémité. Chaque ensemble trépan comprend un bloc et un trépan. Le trépan comprend une pointe conçue pour venir en prise avec une surface de mine. Le trépan définit un axe de trépan et l'axe de trépan délimite un premier angle d'inclinaison par rapport au plan de tambour. La pluralité d'ensembles trépans comprend une première série de quatre premiers trépans, une deuxième série de deux deuxièmes trépans, une troisième série de deux troisièmes trépans et une quatrième série de deux quatrièmes trépans. Chacun des premiers trépans comprend une première pointe et délimite un premier axe de trépan orienté selon un premier angle d'inclinaison par rapport au plan de tambour. Le premier angle d'inclinaison est compris entre environ 60 degrés et environ 75 degrés.
