Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.
Example 1: as shown in attached figures 1-3, a bidirectional anti-sticking drill bit with flushing and slag-smoothing functions for coal mines comprises a drill body 5, and is characterized in that: the bottom end of the drill body 5 is provided with a drill rod joint 4, the outer side wall and the top end of the drill body 5 are provided with a plurality of blades 6, slag return gate grooves 1 are arranged among the blades 6, a water tank 3 is arranged inside the drill body 5, the top end and the side wall of the water tank 3 extend out of the drill body 5, and the bottom end is communicated with the drill rod joint 4.
Further, the high-strength alloy sheet 2 is arranged on the side wall of the blade 6.
The high-strength alloy sheet 2 is welded on a drill body 5, a drill rod is connected with a drill bit through a drill rod connector 4, the drill bit provides power when drilling, the high-strength alloy sheet 2 above the drill bit cuts a rock body, pressure water rushes onto the high-strength alloy sheet 2 through a water tank 3 to cool the high-strength alloy sheet 2 in the drilling process of the drill bit, and meanwhile, slag is returned out of a drill hole through a slag return crossheading 1; when the drill bit is withdrawn, the high-strength alloy sheet 2 at the bottom of the drill bit cuts the broken rock body or the hole collapse part. The slag is flushed out of the bore hole by the water pressure of the bore hole. Thereby achieving the effects of drilling and withdrawing.
The high-strength alloy sheet 2 is communicated with the slag returning water tank 1 from top to bottom, the drill bit is cooled through the water tank 3, the slag is flushed out of the drilled hole through water power, and the high-strength alloy sheet 2 at the bottom of the drill bit cuts the broken rock body or the hole collapse part when the drill bit is withdrawn, so that the purpose of preventing the drill bit from being stuck is achieved.
The high-strength alloy sheet 2 is used as a basic structure of a bidirectional anti-sticking drill bit with flushing and slag-smoothening functions for an underground coal mine and is arranged at the upper part and the lower part of the drill bit, a drill rod of the high-strength alloy sheet is connected with the drill bit through a drill rod interface, and the drill bit is cooled through a water tank 3 and crushed slag is flushed out of a drilled hole through water pressure when the drill bit is drilled and withdrawn; thereby playing the effect of preventing sticking.
The introduction of the bottom high-strength alloy sheet 2 controls the conditions of hole collapse or water swelling of rocks and the like of the drilled hole after drilling, and the crushed slag of the hole collapse or water swelling part of the rocks is flushed out of the drilled hole through water pressure through the rotation of the drilled hole when the drilled hole is withdrawn.
The two-way anti-sticking drill bit bottom with the flushing and slag-following functions for the underground coal mine comprises a high-strength alloy sheet 2, wherein the high-strength alloy sheet is welded on a drill body, drilling is carried out through a drill rod interface 4, the drill bit is driven by a drilling machine to be in forward transmission, a drill rod is withdrawn outwards, when the drill bit passes through a hole collapse area and a mudstone expansion area, the drill bit rotates the high-strength alloy sheet 2 to smash rocks in the hole collapse area and the mudstone expansion area, and broken slag flows out of a drill hole through a slag-returning crossheading 1, so that the anti-sticking drill effect is achieved.
The two-way anti-sticking that has washing and following sediment function bores drill bit top for the colliery in pit, including high strength alloy piece 2 through the welding on the drilling body, provide power through the rig and make the drill bit just pass, when the drilling rod inwards creeps into, the drill bit rotates high strength alloy piece 2 cutting rock, and the disintegrating slag is through returning sediment crossheading 1 outflow drilling to play the effect of creeping into.
A bidirectional anti-sticking drill bit with flushing and slag-smoothing functions for underground coal mines is characterized in that a high-strength alloy sheet 2 is welded on a drill body, a drill rod is connected with the drill bit through a drill rod connector 4, power is provided by a drilling machine when the drill bit drills in, the high-strength alloy sheet 2 above the drill bit cuts a rock body, pressure water is flushed onto the high-strength alloy sheet 2 through a water tank 3 to cool the high-strength alloy sheet 2 in the drilling process of the drill bit, and meanwhile, crushed slag is returned out of a drilled hole through a slag return crossheading 1; when the drill bit is withdrawn, the high-strength alloy sheet 2 at the bottom of the drill bit cuts the broken rock body or the hole collapse part. The slag is flushed out of the bore hole by the water pressure of the bore hole. Thereby achieving the effects of drilling and withdrawing.
The present invention is not described in detail, but is known to those skilled in the art. Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
