Problems solved by technology

However, in the prior art including this technology, there is a common phenomenon that the center of gravity is behind, and when drilling, it is easy to lift, so that the drilling is crooked, and the drill bit is stuck and cannot be pulled out; and, when encountering a hard surface, the protection Insufficient, the strength of the boom, drill frame and related parts is low, easy to crack and damage; the above factors lead to poor working performance of the whole machine, insufficient downforce, slow hole forming speed, and inconvenient operation

Embodiment 1

[0017] Example 1: Such as figure 1 , 2 As shown, the cutting drilling rig of this embodiment consists of a bulldozing blade 1, a bulldozing cylinder 2, a chassis assembly 3, a slewing mechanism 4, a platform assembly 5, a power system 6, a hydraulic system 7, a cab 8, an air compressor system 9. Operating system 10, boom cylinder 11, boom 12, drill frame cylinder 13, drill bit 14, guide limit sleeve 15, travel switch 16, drill frame 17, drill rod 18, power head system 19 and drill rod propulsion system 20 composition.

[0018] Chassis assembly 3 is the walking and chassis part of the present invention. It is set at the bottom end and directly touches the ground. It uses 8.5T four wheels and 450mm widened track shoes to reduce the ground pressure and ensure the stability of the whole machine. Larger drill pipe down pressure improves the efficiency of drilling rigs. A slewing mechanism 4 is provided on the top, and the slewing mechanism 4 can freely rotate 360 ​​degrees on the cha...
