Problems solved by technology

According to the operating principle of the rock drilling machine, it can be known that the rock drilling machine needs to be operated in two steps, and two cutting marks are cut on the rock layer in order to complete the rock drilling operation. Due to the step-by-step operation, the existing rock drilling machine has low working efficiency, which leads to the practicability of the equipment. Lower, rock drills still have room for improvement

Embodiment Construction

[0027] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0028] Such as Figure 1-Figure 6 As shown, a highly efficient pneumatic rock drill for rock excavation includes a support mechanism 1 and two rock drilling units 2, and the two rock drilling units 2 are arranged on both sides of the support mechanism 1 and connected with the support mechanism 1 connect;

[0029] The support mechanism 1 includes a vertically arranged support tube 3, a sleeve 7 and two hinge assemblies, the sleeve 7 is arranged below the support tube 3, and the vertical section of the sleeve 7 is U-shaped. And the opening is upward, and two hinge assemblies are arranged at both ends of the support pipe 3, and the support pipe 3 is connected w...

Abstract

The invention relates to an efficient pneumatic type rock drill for rock excavation. The rock drill comprises a supporting mechanism and two rock drilling units. The two rock drilling units are arranged on the two sides of the supporting mechanism and connected with the supporting mechanism. According to the rock drill, drill marks are engraved on a rock layer by means of the two rock drilling units at the same time, and working efficiency is improved; by adjusting the length of a connecting assembly, a drill bit can drill the rock layer at different angles, the angle of the drill marks is changed, and the function of adjusting the shape of shot holes is achieved; in addition, the height of a supporting pipe and the rock drilling units is changed through the rotation of a drive motor, the distance between the drill bit and the rock layer is changed, the distance between every two adjacent drill marks is adjusted, the shot holes with different sizes can be drilled by means of the device, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to an efficient pneumatic rock drilling machine for rock excavation. 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. Rock drills can be divided into pneumatic rock drills, internal combustion rock drills, capacitor rock drills and hydraulic rock drills according to their power sources. Among them, the pneumatic rock drill is driven by compressed air to make the piston impact forward in the cylinder, so that the fiber head can chisel the rock. Among the rock drills, the pneumatic rock drill has the widest application range. [0003] When the pneumatic rock drill is in operation, the piston performs high-frequency reciprocating motion to con...
