Down the Hole Drilling Rig

Different Types of DTH Drilling Rig
Different Types of DTH Drilling Rig

Down the hole drilling rig is to make the impactor dive into the hole in the process of rock drilling to reduce the energy loss caused by the transmission of the impact energy transmitted by the drill rod, thereby reducing the influence of the hole depth on the rock drilling efficiency. DTH drilling rigs have always been the best-selling machinery of YG Machinery. In addition, there are rock drills, portable water well drilling rigs, backpack drilling rigs, trucked mounted water well drilling rigs, crawler drilling rigs, etc. Please contact us for the latest prices!【Whatsapp/Wechat/Phone/Skype】+8613613856800

    Types of Down the Hole Drilling Rig for Sale

    Roll Column

    Down the hole drilling rig is an impact rotary drilling rig. Its internal structure is different from that of a general rock drilling machine. Its gad distribution and piston reciprocating mechanism are independent, that is, an impactor. The front end is directly connected with the drill bit and the back end is connected with the drill pipe. During rock drilling, the impactor sneaked into the hole and the piston (hammer) in the impactor reciprocates against the shank through the gas distribution device (valve), so that the drill bit impacts the rock at the bottom of the hole. The high-speed rotation of the impactor in the hole is realized by means of a single rotary mechanism, that is, a motor outside the hole or a pneumatic rotating device, which is connected to the drill pipe at the back of the impactor. The power of the rock produced during drilling is washed out of the hole by the air-water mixture, which is injected into the impactor through the center of the drill pipe by the power exhausting mechanism and then enters the bottom of the hole through the air through on the cylinder body of the impactor.

                      The Principle of Use DTH Drilling Rig Installation and Preparation:

                      1. Prepare for the drilling of a rock cavern, the size of the cavern can be determined according to the method of drilling. Generally, when the horizontal hole is drilled, the height of the cavern is 2.6-2.8m. The width of the cavern is 2.5m in the case of the upper hole, the downward hole, or the inclined hole and the height is 2.8m.
                      2. Lead the air-water pipe and lighting circuit to the working face for later use.
                      3. According to the requirements of the design of the hole, the pillars are erected firmly. The upper and lower ends of the pillars are to be covered with wooden boards. The horizontal shaft and the snap ring are mounted on the pillars according to a certain height and direction. The machine is lifted by a hand winch, fixed on the pillars at the desired angle. And then the whole direction of the drill shall be adjusted.

                      Check Before Working:

                      1. When starting work, carefully check whether the gas-water pipeline is firmly connected and there is no leakage phenomenon.
                      2. Check whether the oil injector is full of oil.
                      3. Check whether the screws, nuts, joints, and other parts of each part have been tightened and whether the column is really pushed firmly.

                      Drilling Operation Program:

                      When opening the hole, start the motor first and push the handle of the manipulator after the transfer is normal. Make it get the proper propulsion, and then pull the handle of the control impactor to the working position. After rock drilling, the water valve can be opened to keep the gas-water mixture at an appropriate ratio. Perform normal rock drilling rock. When the advancement work causes the mast to move into contact with the holder, a drill rod is drilled. To stop the motor running and stop supplying air to the impactor, send water, insert the fork into the drill rod groove of the holder, make the motor reverse the slide back, disconnect the joint from the drill rod, and then connect the second drill rod, press this to cycle and work continuously.

                      Characteristic of Down the Hole Drilling Rig:

                      1. The impact energy loss does not increase with the lengthening of the drill rod, the deep hole of the large diameter can be drilled.
                      2. The noise of the working face is greatly reduced.
                      3. The drilling speed is fast, the mechanization degree is high, the auxiliary working time is less and the working rate of the drilling rig is improved.
                      4. Mobile and flexible.
                      5. The quality of the drilling is high.
                      6. A rock that can be drilled medium or hard medium( f≥8 ).
