Embodiment Construction
[0045] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0046] Such as figure 1 As shown, the guiding device includes a drill rod (1), a guide (2) and a drill bit (3) connected in sequence.
[0047] Such as figure 2As shown, the diameter of the drill pipe (1) is consistent with the diameter of the commonly used drill pipe for underground gas drainage in coal mines, with an outer diameter of 73mm and an inner diameter of 50mm. The front and rear threads of the drill pipe are designed in accordance with national standards for easy connection; the inside of the drill pipe is a smooth through hole, and the high-pressure hose can pass through smoothly. The drill rod is beneficial to accurately send the guide to the designated position and drive the guide to turn.
[0048] to combine figure 1 and image 3 , the upper end of the guide (2) is a drill pipe connecting portion (2.1), and the lower end i...
