The utility model provides a drill jumbo and levelling mechanism thereof. The levelling mechanism includes: platform, one end articulate in the armed lever of platform, articulate in the workstation of the other end of armed lever, both ends articulate respectively in the platform with the armed lever lift pneumatic cylinder, both ends articulate respectively in the workstation with the balanced hydraulic pressure jar of armed lever. Balanced hydraulic pressure jar keep with the same length of pneumatic cylinder lifts so that the gesture of workstation remains unchanged. This kind of levelling mechanism can also remain the gesture (the angle of pitch of workstation) of workstation throughout after the armed lever carries out luffing unchangeable, has just so reduced the time of workstation adjustment gesture. In addition, mechanism structure is simple in this kind of leveling, and the reliability is high.
