Efficient type rock drilling equipment used for ore extraction

Abstract

The invention relates to efficient type rock drilling equipment used for ore extraction. The efficient type rock drilling equipment comprises a handle, a housing, a rock drilling mechanism and a plurality of fastening mechanisms, wherein the rock drilling mechanism comprises a fixed plate, a rotary assembly, a rotary shaft, a power supply, an electromagnet, an extrusion board, a magnetic board, abore bit, a plurality of first springs, two conductive assemblies and two connecting assemblies, each fastening mechanism comprises a fastening tube, a telescopic assembly and a fastening assembly, the fastening assembly comprises an elastic pushing rod and a fastening board. According to the efficient type rock drilling equipment used for ore extraction disclosed by the invention, the equipment is conveniently fixed through the fastening mechanisms, so that rock drilling efficiency is prevented from being affected by deviation during rock drilling; moreover, the first springs and the electromagnet of the rock drilling mechanism are utilized to generate downward acting force on the magnetic plate, so that impact force, on a rock layer, of the bore bit is strengthened, drilling marks are conveniently drilled on a hard rock layer, and rock drilling efficiency is improved, and therefore, practicability of the equipment is improved.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a high-efficiency rock drilling equipment used for ore mining. Background technique [0002] The rock drill is a tool used to directly mine stones. It drills holes in the rock formations so that explosives can be put in to blast the rocks, thereby completing the mining of stones or other stone works. In addition, the rock drill can also be converted into a breaker to break hard layers such as concrete. [0003] The rock drill works on the principle of impact crushing. When working, the piston makes high-frequency reciprocating motion and continuously impacts the drill tail. Under the action of the impact force, the wedge-shaped drill bit crushes the rock and digs into a certain depth to form a dent. However, because some rock formations are relatively solid, and when the reciprocating motion of the piston acts on the drill bit, the impact force is limited, and it is difficult to...

AI Technical Summary

Problems solved by technology

However, because some rock formations are relatively solid, and when the reciprocating motion of the piston acts on the drill bit, the impact force is limited, and it is difficult to leave dents on the rock, and the piston needs to perform multiple reciprocating movements, resulting in a decrease in rock drilling efficiency. When drilling rock, the equipment is prone to shaking, which leads to the deviation of the rock drilling position. People need to repeatedly adjust the position of the equipment to align the bit with the dent, which further reduces the working efficiency of the equipment and greatly reduces the practicability.
