Shandong Kerui Petroleum Equipment Co., Ltd

KT11S Type open hole drill is based on developing and producing DTH drills for many years, according to the demand of large open-pit mine, and is an elaborate design new drilling equipment. The Drill walking forward, turning and angle adjustment and other movements adopts hydraulic driven. With the impact of high wind pressure screw and pneumatic impactor, it have high drilling productivity. Equipped with hydraulic dry dust collector to collect dust collection can reduce the pollution to the environment. Also with the hydraulic manipulator and drill pipe library , floating coupling to protect the drill screw, only one person can dismantle the pipe. The air conditioning cab to provide a comfortable working environment, automatic control valve to reduce the card stuck drill chance. Drill car has a high degree of automation, energy efficient, comfortable environmental protection, easy to operate, flexible and adjustable, and safe driving etc. characteristics.

1.Brief introductions of KY-300 hydraulic exploration drilling rig for metal mine KY-300 hydraulic exploration drilling rig for metal mine is suitable for drilling at any angle in the tunnel or surface. It is small in size, light in weight, convenient to install and operate with adjustable speed and good linkage performance. 2.Specifications of KY-300 hydraulic exploration drilling rig for metal mine Drilling diameter (mm) ¸47 Drilling depth (m) 300 (¸43 aluminum alloy drilling pipe) 240(¸43 steel drill pipe) Power 37kw (motor) Weight main engine 295kg/backbone66kg/operating station 86kg/power car 480kg

The draw works is driven by two VFD AC motors with 1+1r/2+2r step-less speed, and reversal will be realized by ac motor reversal. The mud pump is driven by VFD AC motors, which are mounted on the rear skid of mud pump, with v-belt transmission and simple structure. The independent driven rotary table runs with 1+1r/2+2r step-less speed, and reversal will be realized by ac motor reversal. Using AC-DC-AC drive technology, rotary table and draw works are four quadrant running and full digital vector control. Single drum, gear driven and one / two shifts smooth speed change draw works is simple in structure and reliable in operation. Feed back / dynamic brake is adopted to replace eddy current brake as auxiliary brake. Automatic drilling is obtained by draw works main motor or an independent motor. Intellectual position control for traveling block prevents crown block and rotary table from collision. Real time communication and network is available by using profibus technology. K type mast is suitable for install top drive system. Sling shot or swing up substructure and mast are applied so that all the equipment can be installed at lower position. Suit for any transportation.
