Abstract

The invention discloses a mining linkage all-hydraulic drilling machine which comprises a pump station system, a power head, a base, a machine frame, an upright post, a gripper, a drilling tool, a drilling machine thrust cylinder and a hydraulic linkage system, the hydraulic linkage system comprises a multiway valve unit and a linkage unit, the pump station system is connected with the linkage unit by the multiway valve unit, the linkage unit comprises an advance and retreat pole hand-operated direction valve, a cartridge linkage / single acting hand-operated direction valve and a gripper linkage / single acting hand-operated direction valve, the multiway valve unit comprises thrust cylinder valve leaves, hydraulic cartridge valve leaves, gripper valve leaves and hydraulic motor valve leaves.The invention adopts hydraulic linkage function, thus reducing auxiliary time of drilling machine operation, and leading the drilling machine operation to be more convenient. The drilling machine is compact in structure, light in weight and easy to transport in the pit.

Description

technical field [0001] The invention relates to the field of mining machinery and equipment, in particular to a mining linkage full hydraulic drilling rig. Background technique [0002] Existing hydraulic drilling rigs are mainly composed of pump stations, consoles, power heads, racks, underframes, grippers, columns, drilling tools, etc., which are complex in structure and heavy in weight, which is not conducive to underground transportation, and the hydraulic system cannot Linkage, the operation is complicated, time-consuming and laborious. Contents of the invention [0003] In view of this, the present invention provides a linkage full hydraulic drilling rig for mining. By adopting the hydraulic linkage system, the auxiliary time of drilling rig operation is reduced, the drilling rig is easier to operate, and at the same time, it is compact in structure, light in weight, and easy to carry underground. [0004] The purpose of the present invention is to provide a mine li...
