Embodiment Construction
[0026] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0027] The invention discloses a long drilling and punching mechanism, which can be used for drilling rods in coal mine roadways and tunnels in cooperation with equipment such as roadheaders. The following are specific examples:
[0028] The invention relates to a drilling and punching mechanism, which realizes three-stage expansion and contraction by setting three slideways that can move relative to each other and two drill rods. On the premise that the required installation space remains unchanged, it is equivalent to lengthening the length of the slideway, thereby increasing the stroke of the drill pipe. Further, two drill rods can also be set on the drilling and punching mechanism, and different drill bits can be installed on the two drill rods to perform different types of drilling operations.
[0029] In order to achieve three-stage tele...
