[0002] During the process of drilling holes with a drilling rig underground, gas spray holes or water flow from the orifices are likely to appear in the boreholes, and they need to be sealed with anti-blowout pads. During the drilling process, the anti-blowout pads and the drill pipe are in friction for a long time, which can easily cause the anti-blowout pads to break or deform. They need to be replaced in time, otherwise gas will easily leak or spray out, causing gas accidents. Therefore, the use of anti-blowout pads is very large. If you rely solely on purchasing anti-blowout pads to supply underground drilling, not only is the cost high, but the purchase is also not timely, which makes the construction process dangerous. The existing anti-blowout pad machines are not only large and expensive, but also electric and cannot be used underground. Therefore, it is necessary to develop a small-sized, low-cost anti-blowout pad processing device that can be used at any time underground. Utility Model Content

The clamping frame 7 is fixed on the base 1, facing the annular hole opener 6, and a through hole adapted to the outer diameter of the annular hole opener 6 is opened on the clamping frame 7.

[0027] The present invention further includes a connecting shaft 51 and a connecting plate 52 . The connecting shaft 51 is fixed to the middle of the long strip connecting plate 52 . The connecting shaft 51 is connected to the output shaft of the pneumatic drill 5 . Both ends of the connecting plate 52 are connected to the first hole opener 61 by bolts.

[0028] like Figure 2 、 Figure 3 As shown, the annular hole opener 6 includes a first hole opener 61 and a second hole opener 62 arranged concentrically. The second hole opener 62 is fixed in the first hole opener 61. The length of the second hole opener 62 is longer than the first hole opener 61 and extends 2-10 mm outside the first hole opener 61.

[0029] The second hole opener 62 can be fixed to the first hole opener 61 by means of bolts. In this way, the first hole opener 61 and the second hole opener 62 can also be disassembled, making maintenance and replacement more convenient.

[0030] A spring 63 is provided in the second hole opener 62. The spring 63 can eject the circular pad cut by the second hole opener 62 so that it can be easily removed.

[0036] like Figure 4As shown, the anti-blowout leather pad is an annular leather pad. Before the use of the utility model, it is necessary to first use a high-pressure pipe to connect the underground air duct and the air drill 5. The process of processing the anti-blowout leather pad with the utility model is as follows.

[0037] Insert a belt of appropriate width between the fixed plate 71 and the movable plate 72, tighten the two fastening bolts 74 to clamp the belt, start the air drill 5, the air drill 5 drives the annular hole opener 6 to rotate, shake the handle 8, the slide 3 moves under the action of the screw 4, and drives the air drill 5 to advance toward the clamping frame 7. The second hole opener 62 first contacts the belt and cuts, and then the first hole opener 61 contacts the belt and cuts. After both hole openers have finished cutting, the anti-spray leather pad is processed. Turn off the air drill 5, remove the processed anti-spray leather pad, shake the handle 8 in the opposite direction, so that the slide 3 drives the air drill 5 to retreat, tighten the fastening bolts 74, and the clamping frame 7 loosens the belt and pulls the belt for a distance. Repeat the above process to process the next anti-spray leather pad.
