FIELD: mining industry; applicable in drilling of blast holes. SUBSTANCE: drilling manipulator has drilling machine located on guide girder made integral with the link of eight-link mechanism of high class with two closed circuits made in form of hinged multimember with base four-hinge link which is hinged by its one hinge unit base and the other three, with double-hinged links. Tetragonal and pentagon circuits of this mechanism are closed between each other by three-hinged links. Free hinge of link connects it with additional double- hinged link, which, in its turn, is connected with base and moved by rotary drive. EFFECT: higher productivity of manipulator due to accuracy in positioning of drilling machine - automatic blast hole drilling with no displacement of tool relative to axis of mine working. 1 dwg |
