With the combination of the above embodiments, the specific working principle and working process of the present invention are as follows:
before the concrete core 130 is clamped, in order to smoothly install the concrete core 130, the first control module 190 is driven to enable the pressing plate 280 to be far away from the clamping position, the second control module 210 is driven to control the second connecting piece 220 to drive the clamping plate 230 to move upwards, then the second control module 210 is used for controlling the second connecting plate 120 to slide in the sliding groove and to be away from the right upper end of the concrete core 130, and the clamping plate 230 is far away from the clamping device.

The control box 100 is electrically connected to the second motor, and the control box 100 is used for driving the second motor to rotate. The second motor can drive the moving control member 160 to move, and when the moving control member 160 moves, the drill head 140 is pushed to move, so that the first compression spring is pressed.
Fig. 5 is a schematic force diagram of the concrete core 130, where the positions a and B are force application directions of the two drill bits 140 to the two side walls of the concrete core 130, respectively, so that when the drill bits 140 drill concrete, the sum of the torques at the positions a and B will act on the concrete core 130, so that the torque applied to the concrete core 130 is unbalanced, and has a tendency of counterclockwise rotation, and therefore, the conventional sampling device is likely to displace when the drill bits 140 drill holes, thereby affecting the sampling accuracy. The force application directions of the two balancing mechanisms to the two side walls of the concrete core 130 are respectively arranged at the position C and the position D, the torque at the position C is balanced with the torque at the position B, the torque at the position D is balanced with the torque at the position A, the stress borne by the concrete core 130 is balanced on the whole, and the problem that the drill bit 140 is easy to displace during drilling is solved.
The moving speed of the drill 140 is controlled by controlling the moving speed of the moving control member 160, so that the speed of the drill 140 is relatively low when the drill 140 is just in contact with the concrete core 130, namely, the compression amount of the first compression spring arranged between the drill 140 and the moving control member 160 is relatively small, the positive pressure of the drill 140 on the concrete core 130 is reduced, and the damage degree on the end surface of the concrete core 130 is further reduced. Meanwhile, a sensor is arranged in the first control module 190 and can sense the distance between the drill bit 140 and the movable control member 160, namely, the compression amount of the first pressure spring, so that the connecting rod 250 is controlled to move relative to the connecting pipe 240, the connecting rod 250 moves to compress the second pressure spring between the pressure control rod 270 and the pressure plate 280, the acting force of the pressure plate 280 on the concrete core 130 is increased in the same proportion, namely, the first control module 190 can adjust the compression amount of the second pressure spring according to the compression amount of the first pressure spring, and the compression amount of the first pressure spring and the compression amount of the second pressure spring are adjusted in the same proportion. And further ensuring that the torque at the position A is balanced with the torque at the position D, and the torque at the position B is balanced with the torque at the position C. Synchronous adaptation can be performed throughout the drilling process.
When the drill 140 drills the middle of the concrete core 130, the moving speed of the drill 140 can be controlled by controlling the moving speed of the moving control member 160, so that the speed of the drill 140 is increased when the drill 140 is just in contact with the concrete core 130, thereby increasing the drilling efficiency, and before the drilling is finished, namely, the drill 140 comes from one side surface of the concrete core 130 to the other side surface opposite to the side surface, in order to avoid the damage of the test piece, the moving speed of the drill 140 is reduced again by controlling the moving speed of the moving control member 160, namely, the positive pressure of the drill 140 on the concrete core 130 is reduced again before penetrating through the concrete core 130. The reduction of the positive pressure can prevent the second compression spring between the pressure plate 280 and the pressure control rod 270 from being reset when the drill 140 passes through the concrete core 130, so that a large torque is generated on the concrete core 130 to damage the test piece.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the scope of the present invention, which is intended to cover any modifications, equivalents, improvements, etc. within the spirit and scope of the present invention.
