[0037] At the same time, the contents not described in detail in this specification belong to the existing technology well known to those skilled in the art.

[0038] The user moves the adjustment member 2 and the detection member 3 to the concrete sampling end for civil construction through the movable seat 1, and adjusts the horizontal position of the movable seat 22, the electric push rod assembly 4, the drilling member 24, the first driving member 25, the second hydraulic cylinder 26, the pressure block 27, the second driving member 28, and the lifting seat 29 through the first hydraulic cylinder 23, so that the drilling tube 241 moves to the upper side of the end to be sampled, and starts the first motor 251. The first motor 251 cooperates with the first gear ring 253 through the first gear 252 to drive the drilling tube 241 to rotate, and adjusts the height of the lifting seat 29, the drilling member 24, the first driving member 25, the second hydraulic cylinder 26, the pressure block 27, and the second driving member 28 through the electric push rod assembly 4.

The output end 81 is locked to achieve the clamping and fixation of the concrete sample core, and the height and horizontal position of the drilling member 24 are adjusted to move the bottom of the concrete sample core to the upper side of the support plate 33, and release the lock of the sample core. At this time, the support plate 33 provides support for the sample core, and the pressure sensor 32 detects the weight of the sample core through the support plate 33, and starts the second hydraulic cylinder 26. The second hydraulic cylinder 26 drives the pressure block 27 to press down the sample core located inside the drilling tube 241. During this process, the pressure sensor 32 continuously detects the pressed weight of the sample core through the support plate 33 to achieve the detection of the concrete sample core. The pressure sensor 32 is a prior art, and its internal specific structure and working principle are not described in detail.
