A down-the-hole rock drill for mine development capable of quasi-angle positioning

Abstract

The invention discloses a down-the-hole rock drill for mine mining capable of quasi-angle positioning in the technical field of mining equipment. The front end surface of the horizontal plate is provided with a front moving plate, the rear end surface of the front moving plate is horizontally provided with a sliding bar, and the front end surface of the horizontal plate is horizontally provided with a sliding bar rail matching the sliding bar, and the sliding bar is movably arranged In the inner cavity of the matching slide rail, a positioning base plate is connected to the top of the front moving plate, an electric hydraulic press is arranged on the top of the positioning base plate, and a drill rod is fixedly connected to the electric hydraulic machine, and the outer periphery of the drill rod is fixed The socket is provided with an outer fixing ring, wherein a group of the longitudinal plate side walls are provided with a motor bottom plate, and the top of the motor bottom plate is welded and fixed with a deceleration motor 1. The down-the-hole rock drill can achieve quasi-angle positioning during use. It can also achieve precise control of the chisel depth.

Description

technical field [0001] The invention relates to the technical field of mining equipment, in particular to a down-the-hole rock drill capable of quasi-angle positioning. Background technique [0002] A rock drill is a tool used to directly mine stone. It drills blastholes in rock formations so that explosives can be put in to blast the rock, so as to complete the mining of stone or other stonework. In addition, the rock drill can be converted into a breaker to break up hard layers such as concrete. [0003] Mining is very difficult, especially in the first step of the rock drilling and seam opening procedure, which requires effective seam opening, so that the related equipment in the later stage can be effectively involved, but most of the existing seam openings have simple structures. , it is impossible to move flexibly in the process of chiseling to find the angle of the chisel, and the depth of the chisel cannot be accurately positioned, resulting in a poor chisel effect...

AI Technical Summary

Problems solved by technology

[0003] Mine mining is very difficult, especially in the first step of rock drilling and slit drilling, it is necessary to effectively slit so that the relevant equipment in the later stage can effectively participate, but most of the existing slits are simple in structure , it cannot be moved flexibly during the chiseling process to facilitate the identification of the chiseling angle, and the depth of the chiseling cannot be accurately positioned, resulting in poor chiseling effect. Therefore, a down-the-hole Rock drills are of real value
