Small outrigger down-the-hole drilling rig drilling rock

 The small outrigger down-the-hole drilling rig is suitable for large-diameter blasthole drilling in small and medium-sized mines, road construction, water conservancy and stone works, as well as drilling anchor holes in slope support,foundation pit support and tunnel support,ect. The mini rock drilling rig’s main drilling object is the rock formation. Down-the-hole drilling is based on road, railway, water conservancy, hydropower, mine construction and other projects.

 

The roads are inconvenient in the early stage of construction, and lifting and transportation equipment cannot directly transport the equipment to the construction site. The down-the-hole drilling rig eliminates the need for hydraulic pressure, resulting in high mechanical efficiency, low cost, and high performance. The down-the-hole drilling rig is suitable for coal mine tunneling, mine tunneling, mining, water conservancy construction, road construction and stonework. It has the characteristics of reasonable structure, convenience, easy operation and reliability.

product description

The down-the-hole drilling rig is a percussion rotary drilling rig, and its internal structure is different from that of a general rock drilling machine.  Its gas distribution and the reciprocating mechanism is the impactor. The front end connects to the drill bit directly, and the rear end is connected to the drill pipe.  When rock drilling, the impactor dives into the hole, and through the gas distribution device (valve), the (hammer body) in the impactor reciprocates to strike the shank tail, so that the drill bit generates a whirling force against the rock at the bottom of the hole. Product features: small size, light weight, suitable for places where large and medium-sized drilling rigs cannot work, convenient and flexible. The down-the-hole drilling rig is powered by electric energy, with low noise and strong power. The drilling speed of the small drilling rig is 3-8 times that of ordinary rock drills, the rock hardness reaches 9, and the drilling depth per hour is 8-16 meters.

Advantages of down-the-hole drilling rigs

1. Compact design, strong maneuverability,
2. Fast, flexible, high maneuverability, high driving force and smart design of the drilling rig make KS168 have excellent climbing ability even under harsh terrain conditions. The swing-type crawler walking device is adopted, and the walking speed is as high as 3.5 kilometers per hour. The low center of gravity design makes it more agile and stable.
3. Energy saving: switch to gear transmission output, the power is more direct and powerful, and the air consumption is 50% higher than that of the vane air motor, so as to achieve the purpose of energy saving and avoid the trouble of replacing the vane. The whole machine is suitable for engineering design, wide field of view and easy operation of the joystick, which improves the operator's comfort and production efficiency.

3. Classification method of down-the-hole drilling rigs
According to the way of walking: small outrigger down-the-hole drilling rig large crawler down-the-hole drilling rig
Divided by working power: gas-electric linkage SKD, full pneumatic
According to the wind pressure level: low wind pressure L, medium wind pressure M, high wind pressure H
According to the hydraulic power configuration of the drilling rig: diesel-powered, diesel-electric dual-purpose, electric
Fourth, the advantages of down-the-hole drilling rig
It has good drilling performance, and can effectively drill holes in hard formations, and the efficiency is very high. It is suitable for rock formations with high hardness, weathered rock formations and various hard and brittle geological environments. Disadvantages: It is difficult to remove chips, and it is very difficult to drill holes in soft geological and viscous soil layers. Use has certain limitations.
