Abstract
La présente invention concerne un dispositif servant à refroidir le burin formant l'outillage des têtes des haveuses. Ce dispositif utilisant des buses délivrant des jets 7a, 8a, 9a, 10a, d'eau pulvérisée dans de l'air, se caractérise en ce que lesdites buses sont prévues sur le bras de havage 1 dans le sens de la taille à effectuer, en arrière de la tête de havage 2. Ces buses sont reliées à une source d'air comprimé 5 dans laquelle débouche au moins un canal d'amenée d'eau. Les axes 7a, 8a, 9a, 10a des buses précitées sont orientées sur le côté de la tête de havage 2 sur lequel les burins 2' sortent de la roche à entailler. L'invention permet de réaliser une importante économie d'eau.
