Drilling device for geotechnical engineering investigation and capable of accurately controlling drilling depth

Abstract

The invention discloses a drilling device for geotechnical engineering investigation and capable of accurately controlling drilling depth, and particularly relates to the field of machine. The drilling device comprises a plate body and is provided with a first hydraulic cylinder and a sliding groove; a first hydraulic cylinder drives a connecting plate to move downwards through sliding blocks and supporting rods, then the connecting plate drives the supporting rods fixedly connected to the two sides of the connecting plate to be in sliding connection on one side of the supporting plate, and therefore the sliding blocks fixedly connected to one sides of the two supporting rods are in sliding connection in sliding grooves formed in one side of the supporting plate, a worker can better control the drill bit to accurately measure the depth during exploration of the drilling depth; a clamping groove, a clamping block, a second hydraulic cylinder and a rotating shaft are installed, the clamping block and the corresponding clamping groove can be movably connected by the worker, and therefore the rotating shaft movably installed on the inner wall of the clamping groove adjusts the angle of the clamping block through rotation of a connecting shaft; and an external power switch for externally controlling the second hydraulic cylinder is turned on, so that the supporting effect of the device is effectively improved.
