The invention relates to a drilling machine for engineering supervision. The drilling machine comprises a machine shell, a probe rod and a drop hammer, wherein the probe rod is arranged on a bottom plate of the machine shell in a penetrating mode; a mounting plate parallel to the bottom plate of the machine shell is fixedly connected in the machine shell; the drop hammer is located between the mounting plate and the probe rod; an ejection mechanism used for ejecting the drop hammer is arranged on the mounting plate; the ejection mechanism comprises a sliding rod, a spring, a rack, a driven gear and a driving gear; one end of the sliding rod is fixedly connected with the drop hammer, and the other end of the sliding rod penetrates through the mounting plat; the spring is arranged on the sliding rod in a sleeving mode; one end of the spring is fixedly connected with the bottom surface of the mounting plate; one end of the rack is fixedly connected with the drop hammer; the other end of the rack penetrates through the mounting plate and is in sliding connection with the mounting plate; the driven gear is rotationally arranged on the mounting plate and is meshed with the rack; the driving gear is rotationally arranged on the mounting plate and is meshed with the driving gear; the diameter of the driving gear is smaller than that of the driven gear; and a driving mechanism for driving the driving gear to rotate is arranged on the mounting plate. The drilling machine has the advantages of being small in size and convenient for constructors to carry and use.
Description
technical field [0001] The application relates to the field of engineering supervision, in particular to a drilling machine for engineering supervision. Background technique [0002] Brazing exploration is to inspect the soil layer below the bottom of the foundation pit according to the regulations after the excavation of the foundation pit reaches the design elevation, judge the softness and hardness of the soil, and detect whether there are pits, ancient tombs, ancient wells, air-raid shelters and underground Burial objects, etc. Engineers and technicians can drive the drill rod into the ground, and according to the number of hammering required for the drill rod to enter a certain depth of the foundation to be detected, detect the hidden structure in the soil layer or estimate the allowable bearing capacity of the soil layer. [0003] In the prior art, the publication number is the Chinese patent of CN207714301U, which discloses a drilling machine, comprising a frame, a d...
