Problems solved by technology

[0002] At present, when the poles of power supply lines are operated on poles, they are generally constructed manually or with the cooperation of cranes and manual labor. The labor intensity is high and the cost of digging holes is high. Later, digging machines appeared to solve the above problems.
[0003] Existing digging machines use fixed-diameter drills, which are first drilled with small drills, and then reamed with large drills. In actual operation, the equipment needs to carry a large number of drills, and the drills need to be replaced frequently during operation. Inconvenient; in addition, the existing drill bit has no related soil export structure in design. When the drill bit drills to a certain depth, the drilling resistance of the drill bit increases due to the soil being compacted by the drill bit. Inconvenient to use
