Technical Field

[0001] The utility model relates to the technical field of drilling equipment, in particular to a steel rod drilling equipment. Background Art

[0002] Steel rod drilling equipment is a kind of equipment that uses steel rods for drilling operations. It is usually composed of steel rods, a drive system and a drill bit. The steel rod is the main component of the equipment, which is used to transmit driving force and rotational force to the drill bit. The drive system is responsible for providing driving force and controlling the rotation speed of the drill rod. The drill bit is a key tool for drilling and is used to cut underground rocks or soil. Steel rod drilling equipment can be used for drilling tasks in various construction, geology, water conservancy and mining projects. It can be used for sampling, underground exploration, foundation treatment, ore mining and other operations. Steel rod drilling equipment is flexible and efficient, and can adapt to drilling needs of different types and depths.

[0003] However, since the steel rod is a cylinder, the existing drilling equipment is prone to causing the steel rod to rotate when drilling holes in the steel plate, and the axis of the steel rod is also prone to shifting during drilling, which in turn causes the drilled hole to shift and results in reduced accuracy.
