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
