を特徴とするさく孔装置用差し角制御装置。A guide cell on which a rock drill is mounted is supported via a boom, and the guide cell is changed in angle by the operation of a lift cylinder, and the lift cylinder and the hydraulic power source are connected to a lift direction switching valve. A drive cylinder of a sub-cylinder consisting of a drive cylinder and a driven cylinder is communicated with the hydraulic power source through a lift hydraulic circuit via an angle control directional switching valve, Further, branch oil passages are led from the oil passages on the lift cylinder side of the lift direction switching valve of the lift hydraulic circuit, and the branch oil passages are communicated with the driven cylinder of the sub-cylinder, and the sub-cylinder is provided with its driving force. A stopper facing one of the chambers is adjustable, facing the sub-cylinder screw, ton, or driven piston, and moves the driving piston or driven piston of the sub-cylinder in the direction toward the stopper. By this, the lift cylinder is expanded and contracted by the predetermined angle of the guide cell by the spilled oil of the driven part cylinder, and the predetermined angle can be made variable by adjusting the stopper. Device.
