DTH Drilling

DTH Drilling Rig Product Description:

The DTH drilling rig is an impact rotary drilling rig. Its internal structure is different from that of a general rock drilling machine. Its gas distribution and reciprocating mechanism is the impactor. The front end is directly connected to the drill bit, the rear end is connected to the drill bit, and the rear end is connected to the drill pipe. During the rock drilling, the impactor is in the hole of the submerged person, and the ( hammer ) in the impactor is struck by the gas distribution device ( valve ) to strike the shank so that the drill bit produces a swirling force on the rock at the bottom of the hole.

Use Introduction of Blast Hole Drilling Rig:

It is suitable for large-diameter blast-hole rock drilling operations in small and medium-sized mines, road construction, water conservancy, and stone works, as well as drilling anchor holes in slope support, tunnel support, and foundation pit support. The main perforated object is a rock formation.

Features of Down the Hole Drilling Rig:

It is small in size and light in weight and is suitable for places where large and medium-sized drilling rigs cannot work. It is convenient and flexible. The DTH drilling rig uses electric energy as power, with low noise, and strong power. The drilling speed is 3-8 times that of the general rock drill, the rock hardness is 9 and the drilling depth per hour is 8-16 meters.

The DTH drilling rig adopts an excellent motor, which has the characteristics of high efficiency, convenient operation, low investment, and high economic benefit. Widely used in slope support, quarry, water conservancy projects, anchor bolts, highway, and railway construction.

SKD70 DTH Drilling Rig:

The SKD70 is a hybrid powertrain with a motor and compressed air. The power of the rig’s rotation is from the motor, and the impact of the impactor comes from the compressed air. When the motor is working, the electric energy is converted into the rotating torque and transmitted to the reducer, so that the drill pipe connected to the output shaft of the reducer rotates, and the alloy drill bit at the front end of the impactor continuously impacts the crushed and crushed rock, and the broken rock is taken from the vent hole of the drill bit. The discharged air pressure is blown to the ground.

The SKD70 rig is light and economical, and it is a negligible road on the construction site and a steep star on the hillside. Mainly used in slope support, highway, and railway excavation construction.

SKD100 DTH Drilling Rig:

The SKD100 rig is also a hybrid powertrain with a motor and compressed air. SKD100 drilling rig is the main model of our company, with stable quality, convenient operation, reasonable design, slope support, quarry, water conservancy project, highway, and railway construction.

SKQ100 DTH Drilling Rig:

The SKQ100 rig is a method of converting compressed air into mechanical force to break rock by using compressed air as power. The power part is a pneumatic motor. The SKQ100 can also be constructed without electricity, with a single power, safe and reliable.

The SKQ100 drilling rig is suitable for water conservancy projects, underground mining projects, road and railway construction, etc.

The SKQ100 column drilling rig is specially designed for tunnel engineering and underground engineering. The column can be adjusted up and down, and the rig is placed on the middle tray for 360-degree rotation.

The SKQ100 long and short carriages are often used on the columns. In both rigs, the upper and lower telescopic cylinders are active throughout the carriage. The long carriage is equipped with a 1-meter drill pipe and the short carriage is equipped with a half-meter drill pipe. This depends on the specific construction environment at the site to decide which rig to choose. Widely used in underground engineering, and tunnel engineering.

SKB120-5.5 DTH Drilling Rig:

The SKB120-5.5 cycloidal drill is a hybrid powertrain with a motor and compressed air. The SKB120-5.5 cycloidal drill has high torque and strong drilling capability. It is the best choice for deep-hole blasting. The SKB120-5.5 drilling rig is suitable for slope support, quarry, water conservancy projects, and highway and railway construction.
