DK-150 Drill Rig（underground drill）is designed for field-exploration and mineral produce, also be used in underground engineering, such as dam's leak closing, mine's water drain off, or leading-besprinkle and concretion of tunnel etc.

1.  Peculiarity of drill

   (1).  The drill uses a general designing scheme. It uses a mechanical swivel head, but feeds and draws rods by hydraulic. It has general advantage of high efficiency of transmission, credible working and high automation in hydraulic feeding and rod drawing.

   (2).   Feeding oil cylinder, hydraulic chuck and hydraulic clamper are driven alone. Drawing rods needn't drilling tower and hoist, screws and unlades rods mechanically. The efficiency of work is increased, the labor intensity is reduced.

   (3).   Using a hydraulic clutch, convenient operation, agility action, regular and accurate of pressure adjusting, and auto-compensate the clutch for its abrasion, prolongs the life-span of grinding flake.

   (4).   The structure of the drill is simple, the weight of it is light, conveniently to dismantle, install, move and maintain.
