Mine field exploration rock stratum sample collection equipment

The invention relates to the technical field of geological mineral exploration sampling, and discloses mine exploration rock stratum sample collecting equipment which comprises a lifting unit, a drilling unit, a cutting unit and a discharging unit. According to the underground rock drilling device, after a drilling motor in the drilling unit is started, a hollow drill rod is driven to start to rotate at a high speed, the hollow drill rod is driven to move downwards through a lifting hydraulic push rod in the lifting plate unit, so that underground rock can be drilled, and after a hole is drilled to a designated position, an operator rotates a connecting base and drives a cutter to rotate through the connecting base; in the rotating process of the cutter, the cutter is pushed to move towards the interior of the rock column by moving an insertion rod on a spiral guide groove, so that the cutter rotates on the rock column in a surrounding manner, and in the rotating process, the cutter is continuously fed so as
