Abstract:
Some embodiments of the present disclosure provide a six-arm tunneling and anchoring machine for integrating tunneling and anchoring, which includes: a tunneling machine and a roof-bolter connected with each other. The roof-bolter includes roof bolt units, a side bolt unit, and a working platform unit. The tunneling machine includes a frame body, a walking part, a cutting part, a revolving body, a rear support body, a loading mechanism, a conveyor, an electronic control system, a hydraulic system, a spraying system and a cooling system. There are two sets roof bolt units, which are symmetrically arranged on the left and right sides of the frame body, and are located behind a revolving center of the revolving body. Each roof bolt unit is provided with two top anchor bolts.
