Therefore, the first translation mechanism 300, the second translation mechanism 400 and the first swing mechanism 500 are cooperated, so as to meet the excavation requirement of more complex action, and further improve the adaptability range.

[0036] It should be noted that the propulsion mechanism 320 can adopt a structure form of telescopic oil cylinder, chain wheel driving or gear driving, and can drive the sliding beam 310 to move linearly, which should not be limited. The direction of the above-mentioned forward and backward movement is parallel to the direction of tunnel excavation, and the left and right movement is perpendicular to the forward and backward movement in the horizontal direction.

The sliding beam 310 is provided with a horizontal moving mechanism 420 at the side end, and the horizontal moving mechanism 420 is used to drive the horizontal moving seat 410 to slide along the sliding beam 310.

[0044] In the embodiment, when it is required to swing the tunneling arm 220 left and right, one of the swing oil cylinders 212 is elongated, and the other swing oil cylinder 212 is correspondingly shortened, so as to drive the connecting frame 211 and the tunneling arm 220 to rotate to one side as a whole. When it is required to rotate to the other side, the two swing oil cylinders 212 are reversely elongated and shortened, so as to realize swing control of the tunneling arm 220, and switch the rock drilling position.

[0045] It should be noted that the connecting frame 211 should be hinged to the side end of the transverse seat 410, and the corresponding hinge structure should only support horizontal rotation.

Among them, the breaking hammer 223 can be a common piston impact breaking hammer, or a high-frequency breaking hammer, and in general, as long as the rock is not too hard, the excavation efficiency of the high-frequency breaking hammer is generally higher than that of the common piston impact breaking hammer.
