A rotating rod 14 is provided on one side of the fixed rod 13, which can rotate. Both ends of the rotating rod 14 are provided with connecting shafts 15, which enable the rotating rod 14 to rotate. A movable plate 16 is provided on the outer surface of the connecting shaft 15. A guide rod 17 is provided on one side of the movable plate 16, which can extend and retract.

A connecting groove 21 is provided, which is adapted to the connecting block 20, and the connecting block 20 is slidably connected to the connecting groove 21, which allows the moving plate 16 to move, thereby allowing the positioning pin 22 to move, and thus allowing the rotating rod 14 to rotate, thereby enabling the equipment to sample the wall and the ground, and thus expanding the applicability of the equipment. A positioning pin 22 is provided on one side of the moving plate 16 and is fixedly connected to the moving plate 16. A positioning hole 23 is provided on one side of the fixing rod 13, which is adapted to the positioning pin 22, and the positioning pin 22 is inserted into the positioning hole 23, which can fix the rotating rod 14, thereby enabling the equipment to sample the wall and the ground, and thus expanding the applicability of the equipment.

[0026] Reference Figure 1 , Figure 2 , Figure 7 , Figure 8 and Figure 9 The protective mechanism 11 includes a fixed sleeve 24, inside which a movable ring 25 is provided. In this embodiment, the movable ring 25 is fixedly connected to the mounting bracket 6. A slider 26 is provided at the bottom of the movable ring 25, and a second spring 27 is provided at the bottom of the slider 26 to block dust, thereby preventing dust from scattering and protecting the health of workers. A groove 28 is provided inside the fixed sleeve 24, which is adapted to the slider 26, and the slider 26 is slidably connected to the groove 28, allowing the movable ring 25 to move. This allows the sampling drill bit 10 to move and sample the concrete. The fixed sleeve 24 has a top rod 29 inside, which is fixedly connected to the fixed sleeve 24. The top of the top rod 29 has a sliding block 30, which is fixedly connected to the top rod 29. The fixed sleeve 24 has a sliding groove 31 inside, which is adapted to the sliding block 30. The sliding block 30 is slidably connected to the sliding groove 31, which can push out the concrete inside the sampling drill bit 10, thereby facilitating the removal of the concrete inside the sampling drill bit 10 and improving work efficiency.

[0027] The implementation principle of this embodiment is as follows: This sampling device for engineering testing is equipped with a base plate 1, the bottom of which is fitted with casters. When using the device, the operator pushes it to the desired position. Then, the operator activates cylinder 4, which pushes the telescopic rod 5 to extend or retract. The extension or retraction of the telescopic rod 5 moves the mounting frame 6 and extends the auxiliary rod 8, which supports the mounting frame 6. The movement of the mounting frame 6 drives the motor 7, which in turn moves the rotating shaft 9, which in turn moves the sampling drill bit 10. The movement of the mounting frame 6 also moves the protective mechanism 11, allowing the fixing sleeve 24 to contact the ground, thus blocking dust and preventing dust from scattering, thereby protecting the health of the operators. At this point, the operator starts motor 7. The working mechanism drives the rotating shaft 9 to rotate, which in turn drives the sampling drill bit 10 to rotate, thereby enabling the sampling of concrete. As the mounting frame 6 moves, it pushes the moving ring 25 to move, which in turn drives the slider 26 to move. Since the slider 26 is slidably connected to the slide groove 28, it can move, thereby compressing the second spring 27, which in turn moves the mounting frame 6. During this process, the sampling drill bit 10 moves downward while the fixed sleeve 24 remains stationary, allowing the push rod 29 to move relative to the sampling drill bit 10. After sampling is completed, the operator pulls out the sampling drill bit 10 using the cylinder 4. At this time, the second spring 27 will return to its original deformation, allowing the push rod 29 to push out the concrete inside the sampling drill bit 10, thus facilitating the removal of the concrete and improving work efficiency.

[0028] When wall sampling is required, the operator pulls the movable plate 16. Due to the sliding connection between the connecting block 20 and the connecting groove 21, the movable plate 16 can move, causing the guide rod 17 to extend and retract, which in turn causes the first spring 18 to extend and retract, disengaging the positioning pin 22 from the positioning hole 23. This causes the rotating rod 14 to lose its limit and rotate. The operator then rotates the rotating rod 14. Once the rotating rod 14 reaches the desired angle, the operator releases the movable plate 16. The first spring 18 then returns to its original shape, pushing the movable plate 16 to move. The movement of the movable plate 16 moves the positioning pin 22, allowing it to insert into the positioning hole 23 and fix the rotating rod 14. This enables the equipment to sample the wall, thus expanding the equipment's applicability.

[0029] Compared with the prior art, the present invention has the following advantages: 1. The sampling device for engineering testing is equipped with a rotating mechanism 2. By pulling the moving plate 16, the connecting shaft 15 can be rotated, which in turn can rotate the rotating rod 14, which in turn can rotate the motor 7, which in turn can rotate the sampling drill bit 10, thus enabling the device to sample both the ground and the wall, thereby expanding the applicability of the device. 2. The sampling device for engineering testing is equipped with a protective mechanism 11, which can block dust through the protective cover. An air pump is installed on the top of the collection box 12, which can draw dust into the collection box 12 through the pipe, thereby preventing dust from flying away, protecting the health of the staff, and making it easy to remove the sampled concrete.
