The invention discloses a novel cable passing drill rod for an underground coal mine, and belongs to the technical field of underground coal mine geological prospecting. The novel cable passing drill rod comprises a workbench, wherein a supporting plate is arranged at the upper end of the workbench; a water feeder is arranged at the upper end of the supporting plate, a drill rod body is arranged on one side of the water feeder, and a motor is arranged inside the drill rod body; and the output end of the motor is provided with a rotating shaft, the other end of the rotating shaft is provided with a drill bit, and a mounting assembly is arranged between the drill bit and the rotating shaft. According to the novel cable passing drill rod for the underground coal mine, by arranging the mounting assembly, when the drill bit needs to be replaced, a pull ring is pulled to drive a clamping rod to slide out of a clamping groove in a mounting rod, meanwhile, a spring is compressed, the clamping rod loses the limiting and fixing effect on the mounting rod, the drill bit is pulled to be taken out of a mounting cylinder, a new drill bit is plugged into the mounting cylinder, the pull ring is loosened, the spring elastically stretches to drive the clamping rod to enter the clamping groove in the mounting rod, and the effect of fixing the drill bit is achieved.
Description
technical field [0001] The invention belongs to the technical field of underground coal mine geological survey, and in particular relates to a novel cable-through drill pipe for underground coal mines. Background technique [0002] Geological prospecting is the abbreviation of geological prospecting work. In a broad sense, it can generally be understood as a synonym for geological work, which is based on the needs of economic construction, national defense construction, and scientific and technological development. research work. According to different purposes, there are different geological exploration work. [0003] The prior art discloses a drilling equipment used for underground geological survey of coal mines. The drill bit of the equipment needs to be replaced after a long period of use, and the drill bit is inconvenient to replace. At the same time, the height adjustment of the original equipment is not accurate enough, which reduces the accuracy of drilling . C...
