Reinforced drill

Abstract

The present invention provides a reinforced drill comprising a first drilling device and a second drilling device. The first drilling device comprises a connecting rod, a connecting barrel, a connecting pipe and a drill pipe. One end of the connecting barrel is closed, and the other end of the connecting barrel is opened. The connecting rod is fixedly connected with the closed end of the connecting barrel. One end of the connecting pipe is in threaded connection with the opened end of the connecting barrel. The other end of the connecting pipe is in threaded connection with the drill pipe. Thediameter of the connecting barrel is greater than that of the connecting pipe. The second drilling device is connected to an inner wall of the connecting barrel. Axes of the second drilling device, the connecting rod, the connecting barrel, the connecting pipe and the drill pipe are in the same straight line. The reinforced drill has multiple purposes, and sampling and drilling can be carried outwithout replacing the drill efficiently and conveniently; drilling resistance can be effectively reduced, slag can be exported, enough activity space is provided, deformation and damage of the drillare avoided, and cost is saved; the exact drilling position can also be positioned to avoid the error of the drilling position.

Description

technical field [0001] The invention relates to the field of drilling machinery, in particular to a reinforced drill. Background technique [0002] With the rapid development of my country's economic construction, the demand for energy is huge. Coal resources, as the main source of energy supply in my country, will be difficult to change for a long time in the future, resulting in the continuous development of the coal industry in the direction of mechanization and automation. At present, drills are often used in engineering fields involving engineering drilling, mine prospecting, etc. However, drills are often easily damaged during the drilling process. Resistance, if the slag cannot be discharged in time to the drill, it provides ample drilling space for the drilling operation. With the continuous increase of the drilling depth, the greater the resistance, it will affect the working efficiency and cause damage to the drill. The function of the traditional reamer is relati...

Problems solved by technology

At present, drills are often used in engineering fields involving engineering drilling, mine prospecting, etc. However, drills are often easily damaged during the drilling process. Resistance, if the slag cannot be discharged in time, it will provide ample drilling space for the drilling operation. With the continuous increase of the drilling depth, the greater the resistance, it will affect the working efficiency and cause damage to the drill

The function of the traditional reamer is relatively single. Drilling and coring sampling need to be performed by an independent reamer. It is relatively troublesome to replace, and it is impossible to save material costs and improve work efficiency.
