The utility model discloses a hill slope geotechnical engineering investigation drilling device, which relates to the field of geological exploration and comprises a bottom plate, a plurality of limit plates are arranged at the top of the bottom plate, a nail plate is arranged at the bottom of the bottom plate, a top plate is arranged at the tops of the limit plates, and a plurality of cylinders are mounted at the bottom of the top plate. The whole equipment is firstly placed at a position to be drilled, the nail plate can increase the friction force between the bottom plate and the ground, the position of the equipment is prevented from deviating in the drilling process, in the drilling process, the air cylinder pushes the mounting plate to move downwards, and the drill bit at the bottom of the mounting plate drills the ground. The moving distance of the mounting plate is controlled by the travel switches, when the travel switch at the top is in contact with the travel switch at the bottom, the air cylinder
