Road slope drilling device

The invention relates to the field of drilling, in particular to a road slope drilling device. Comprising a support and further comprises a drilling mechanism. The drilling mechanism comprises a rotating cylinder, a drilling cylinder, a chiseling cylinder, a chiseling spring, a limiting structure and a control device; when soil is drilled, the driving piece drives the drilling barrel and the rotating shaft to rotate synchronously, and when the drilling barrel is blocked by hard blocks in the soil and stops rotating, the lifting piece drives the chiseling barrel to move upwards by a preset distance to enable the chiseling spring to accumulate force, and then the chiseling spring releases the force to drive the chiseling head to chiseling the hard blocks downwards through the chiseling barrel. And when the chiseling head does not crush the hard block, the chiseling cylinder is repeatedly driven to move upwards, and the chiseling spring releases the force to chiseling the hard block until the hard block is crush
