DETAILED DESCRIPTION
[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Reference Figure 1-3 The concrete sampling device includes a mobile body 1, and also includes: a driving motor 202 connected to the mobile body 1; a rotating shaft 203, fixedly connected to the output end of the driving motor 202; a semi-column ring 2041, sleeved on the rotating shaft 203; a semi-column ring 2042, sleeved on the rotating shaft 203, and the semi-column ring 2041 and the semi-column ring 2042 can be spliced into a complete hollow cylinder; a mounting bolt 205, threadedly connected to the rotating shaft 203, and the mounting bolt 205 is used to mount the semi-column ring 2041 and the semi-column ring 2042 on the rotating shaft 203, and the rotating shaft 203 is provided with a mounting hole 2031, and the mounting bolt 205 is threadedly connected to the mounting hole 2031.
[0029] Before using the device, the semi-column ring 1 2041 and the semi-column ring 2 2042 are installed by installing bolts 205. Figure 3 As shown, semi-column ring 1 2041 and semi-column ring 2 2042 are respectively provided with protrusions and grooves, and the protrusions and grooves cooperate with each other and can be inserted therein to increase stability, and semi-column ring 1 2041 and semi-column ring 2 2042 are both provided with raised teeth at the bottom to facilitate drilling of holes in the concrete surface.
[0030] When in use, the device needs to be moved to the place where sampling is required, and then the driving motor 202 is started. The semi-column ring 1 2041 and the semi-column ring 2 2042 are rotated by the driving motor 202, and then the concrete surface is damaged by the teeth, and then it continues to go deeper, and finally a cylindrical concrete is obtained. At this time, the sampling is completed. After the sampling is completed, the semi-column ring 1 2041 and the semi-column ring 2 2042 can be separated by rotating the mounting bolt 205, and the concrete inside can be easily taken out.
[0031] Embodiment 2:
[0032] Reference Figure 1-3The concrete sampling device is basically the same as that of Example 1, and furthermore, a plurality of arc frames 101 are fixedly connected to the mobile body 1, a mounting frame 102 is slidably connected inside the arc frame 101, a driving motor 202 is connected to the mounting frame 102, a driving motor 1 105 is fixedly connected to the mounting frame 102, a fixing rod 103 is fixedly connected inside the mounting frame 102, a screw rod 104 is rotatably connected inside the mounting frame 102, and the screw rod 104 is rotatably connected to the driving motor 1 The output end of 105 is fixedly connected, a sliding block 201 is threadedly connected to the screw rod 104, the sliding block 201 is slidably connected to the fixed rod 103, the driving motor 202 is fixedly connected to the sliding block 201, and a limiting rod 1021 is fixedly connected to the mounting frame 102, the limiting rod 1021 is slidably connected in the arc frame 101, and a limiting nut 1022 is threadedly connected to the limiting rod 1021, and the limiting nut 1022 is used to fix the mounting frame 102.
[0033] During actual use, the angle between the mounting frame 102 and the ground can be adjusted through the arc frame 101. After adjusting to a suitable angle, the mounting frame 102 can be fixed by tightening the limit nut 1022. Then, the driving motor 105 can be used to make the semi-column ring 1 2041 and the semi-column ring 2 2042 continuously approach the concrete surface. When they are close, the driving motor 202 can be started and the driving motor 105 can be rotated slowly at the same time, so that the semi-column ring 1 2041 and the semi-column ring 2 2042 can continuously penetrate into the concrete, so as to obtain cylindrical concrete and complete the sampling.
[0034] The utility model can be separated by setting the semi-column ring 1 2041 and the semi-column ring 2 2042, so that the cylindrical concrete inside can be easily taken out to reduce damage. At the same time, through the setting of the arc frame 101, holes can be drilled at an angle, which is convenient for practical use.
