Introduction

1. Size: 661×247×195mm with 26kg

2. Application: Hand held rock drilling machine is a kind of impact drilling machine powered by compressed air, which is widely used in mines, tunnels, bridges and other engineering fields. It is suitable for drilling small diameter and shallow holes, such as downward or near horizontal holes. It is less used in underground mines due to its dependence on human operation, high labour intensity, low impact energy and torque, and slow rock drilling speed.

Details

The hand held rock drilling machine is a kind of machine which is installed on the air leg and relies on the compressed air to push the piston to reciprocate and realise the rock breaking and drilling. The following is the detailed introduction of hand held rock drilling machine:

Working Principle

The hand held rock drilling machine pushes the piston to carry out reciprocating motion through compressed air. In the stroke, the piston strikes the end of the brazing tool, generating impact force; in the return stroke, the piston drives the brazing tool to rotate, realising rock crushing and drilling.

Scope of Application

The hand held rock drilling machine is suitable for wet rock drilling operation in medium hard or hard rock. Its horizontal or with a certain inclination of the shell hole, widely used in mining, railway, traffic, water conservancy construction and other stone works.

Product Features

◆ Easy operation: The operation mechanism of hand held rock drilling machine is centralised, flexible start-up, gas-water linkage, easy to use and easy to maintain.

◆ High efficiency and energy saving: The machine parts have long service life, high generality, good reliability, and strong function of blowing and washing the shell hole, large torque of rotary brazing, high efficiency of rock drilling.

◆ Reducing labour intensity: As the air leg can play the role of support and propulsion, it reduces the operator's labour intensity.

Uses

Application of Rock Drilling Machine

Rock drilling machine, especially YT28 hand held rock drilling machine, is a kind of high-efficiency rock drilling machinery, and its application range is very wide.

Mining

Rock drilling machine plays an important role in mining, especially drilling blasting holes in roadway boring and various rock drilling operations. It is metallurgy, coal and other mining industry indispensable important equipment.

Transport and water conservancy construction

In the railway, highway, tunnel and water conservancy project stone excavation, rock drill is also often used for drilling blast holes to improve construction efficiency and quality.

National defence and geological engineering

In addition, rock drills are also widely used in national defence stone engineering and geological exploration, for drilling a variety of holes.

FAQ

Q: What are the common failures of hand held rock drilling machines and how should they be handled?

A: Hand held rock drilling machine common faults and treatment methods include:
● Reduced rock drilling speed: Possible causes are low working air pressure, air leg expansion and contraction, insufficient lubricant. Treatment methods include adjusting the pipeline to eliminate air leakage, increase the diameter of the air supply pipe, add oil to the oil injector.
● Air leg failure: Such as air leg rubber bowl wear, frame and outer tube loose, etc.. Treatment methods include replacing or reassembling the air leg rubber bowl, tighten the frame, etc.

Q: How to correctly use and maintain the hand held rock drilling machine?

A: Correct use and maintenance of hand held rock drilling machine need to pay attention to the following points:
● The machine is injected with antirust oil before leaving the factory, and should be disassembled and cleaned before use, and lubricating oil should be applied to the mating surface when it is reassembled.
● When connecting the air pipe must be blown clean of debris in the pipe, so as to avoid debris into the machine research damage to the machine parts.
● Before starting the machine, you must carefully check whether the operating mechanism and running parts are assembled correctly and reliably, the oil injector should be filled with lubricating oil, and adjust the oil volume.
● The end of the machine work, you should cut off the water supply and then lightly run for a moment, blowing the residual water droplets in the machine to prevent parts rust.
● Commonly used machines, should pay attention to regular maintenance and repair, at least once a week should be checked to remove the machine dirt, replace damaged and failed parts.
