Down the Hole Drilling can drill holes in rocks of medium hard or above (f≥8). Like the rock drill, it has the process of impacting, rotating, discharging and advancing the rock drilling hole. The difference is the impact mechanism of the DTH drilling rig-the impactor is installed on the front end of the drill pipe, submerged into the bottom of the hole, and then drilled The extension and continuous advancement. Down the Hole Drilling is named after the impactor diving into the hole. It has the following advantages in use:

• 

• 

1. There is no energy transmission loss, the impactor directly acts on the drill bit, no drill rod is required to transmit impact energy, and the drilling speed is not affected by the hole depth.

2. The hole is straight, the drill pipe has high rigidity, does not bear impact force, only transmits torque, and the transmitted shaft pressure is very small. During decompression drilling, there is no need to transmit shaft pressure at all, so the drill pipe is not easy to bend and deform. The blasthole is straight and smooth, especially when there are cracks in the rock, the bevel is inclined or the hardness of the rock changes, it is better than other drilling methods.

• 

• 

3. The slag discharge is clean, and the motive medium can also flush the blast hole after working, which is more clean than other drilling methods and avoids over-drilling.

4. The noise is small because the impact is carried out at the bottom of the hole, it is less noise than the top hammer.

5. Good adaptability. Except for very soft formations, DTH drilling machine is in the best working condition in all rock tissues, and the drilled hole diameter and hole depth are more than top hammer rock drills.

Due to the above advantages, Down the Hole Drilling is considered the best choice, and down the hole hammer is used in the quarry.

• 

• 

The rock drilling equipment for down-the-hole rock drilling is DTH drilling rig. The essence of down-the-hole rock drilling is to make the impactor dive into the hole during the rock drilling process to reduce the energy loss caused by the impact energy transmitted by the drill rod, thereby reducing The effect of small hole depth on drilling efficiency. Depending on the place of use, Down the hole drilling can be divided into two categories: downhole and open-air. Downhole DTH drilling machines can be divided into self-propelled and non-self-propelled according to whether there is a walking mechanism. According to the difference in diameter, down-the-hole drilling rigs can be divided into light-duty down-the-hole drilling rigs (aperture of 80~100mm) and medium-sized down-the-hole drilling rigs ( The hole diameter is 130~180mm), heavy-duty down-the-hole drill (the hole diameter is 180~250mm).

The floor grinding machine is controlled by a stepless speed regulation system, which can easily adjust the grinding speed suitable for grinding various parts. Adopt electric-pneumatic proportional valve closed-loop feedback pressure control, which can independently control the pressure device.
