Abstract
(EN)
The invention relates to a rock drilling apparatus and a mechanical conveyor for drill cuttings. The conveyor is provided with a sensor (68, 72, 76) for detecting when the conveyor has possibly jammed. The detection data of the sensor is supplied to a control unit (70) of the conveyor, which commands an actuator (31) driving the conveyor to drive the conveyor in a direction that is opposite to the normal direction of conveyance for a predetermined period of time.
(FR)
L'invention concerne une perforatrice de roches et un convoyeur mécanique de déblais de forage. Le convoyeur est pourvu d'un capteur (68, 72, 76) servant à détecter un engorgement possible du convoyeur. Les données de détection du capteur sont transmises à une unité de commande (70) du convoyeur, qui commande un actionneur (31) qui fait rouler le convoyeur dans une direction opposée à celle dans laquelle s'effectue normalement le transport, pendant une période de temps prédéterminée.
