High-precision auger

Abstract

The utility model provides a high-precision auger, which relates to the technical field of auger drills, and comprises a support frame, a high-precision drilling structure is rotatably connected in the support frame, the high-precision drilling structure comprises a support plate, the top of the support plate is connected with a lifting motor, and the top of the lifting motor is connected with a hydraulic cylinder. A one-way screw is fixedly connected to the output end of the lifting motor, sliding rods are connected to the surfaces of the two sides, close to the one-way screw, of the supporting plate, and a moving plate is connected to the surface of the one-way screw. According to the drilling device, during drilling, the drilling motor and the screw rod can be driven by the moving plate to move downwards, and the drilling motor and the screw rod can slide through the sliding rod while moving downwards, so that the accuracy and the stability during drilling are improved, and the problem that follow-up use is affected due to the fact that the drilling position is not accurate enough due to shaking during drilling is solved.
