KG920A mining crawler drilling rig is an improved type of DY125, Optimized and updated pneumatic system, hydraulic system, drill boom, walking parts and so on, which made the stronger climb ability, reasonable drill angle, faster rotary and feed speed, longer service life of motor and more reliable.
1.Powerful feeding and rotating system
The feeding structure by large power hydraulic motor can supply strong torque reserve and reduce the sticking rate.The feeding structure can supply a lifting power of 20N by large power hydraulic motor. Adjust the control vavle on the operating valve can obtain the needed optimum propelling effort.
2.Adjustable boomAdopt adjustable boom, the dip angle of hole and Level hole height can adjust by control the oil tank stretch out and draw back. Also enlarge the drilling scope and improved the adaptability.
3. Reliable hydraulic system
Adopt two independently gear pump.to supply the oil. Working reliable, adaptablity strong and maintain convenient.
Adopt gear drive and soft characteristics connection, structuer compact and working stable.
Adopy special hhydraulic component, improving the sysyten stability and reliability.
Add the oil cooling device, eliminate the effort of oil heating to the system.
4. Centralized operating system
Drill carriage designed with advanced hydraulic system and completely functional gas circuit system. Centralized control ,operate easily.
Hydraulic maneuvering valve can be achieve lift ,swing and drilling rig 's pitching ,swing ,forward and back,also can make track equal .Ensure drill hole drilling rock in different and the stability .
Operating pneumatic manoeuvring valve, which can realize the pump of opening and drill the advancement of car (ascension), and turn to dust collector, impact and set the dust collection, the blow function, ensure efficient car rock drill.
