[0021] Please see Figure 1-4 As shown, this embodiment is a concrete blasting sampling device, comprising: The main component includes a movable frame 1 and a support plate 13. The support plate 13 is fixedly installed on the inner wall of the movable frame 1. The movable component includes an electric push rod 12, a fixed sleeve 14, a movable rod 10, a groove, a fixed rod 9, a conversion block 8, a push rod 6, a rotating shaft 2, a mounting plate 4, a roller 3, an insertion rod 16, a through port 5, and a push plate 7. The surface of the telescopic end of the electric push rod 12 is fixedly connected to the inner wall of the fixed sleeve 14. The front and rear sides of the fixed sleeve 14 rotate with the inner wall of the movable rod 10. The groove is opened on the left and right sides of the movable frame 1. The two ends of the fixed rod 9 are fixedly connected to the movable frame 1. The surface of the conversion block 8 is fixedly connected to the top of the push rod 6. The surface of the rotating shaft 2 is rotatably sleeved in the movable frame 1. The surface of the rotating shaft 2 is fixedly connected to the mounting plate 4. The upper end face of the roller 3 is fixedly connected to the upper end face of the mounting plate 4. The top of the insertion rod 16 is fixedly connected to the lower end face of the movable frame 1. When the electric push rod 12 extends or retracts, it can drive the movable rod 10, which can pull the conversion block 8 to flip. Then, the conversion block 8 pulls the push rod 6, and under the action of the rotating shaft 2, the mounting plate 4 is flipped, so that the mounting plate 4 drives the roller 3 to contact and detach from the ground, which facilitates the transfer of the device and makes the device stable and smooth during the sampling process. All openings 5 ​​are opened on the inner wall of the mounting plate 4, and the surface of the push rod 6 is sleeved inside the mounting plate 4; The push rod 6 is fitted into the mounting plate 4 through the through-hole 5, causing the mounting plate 4 to rotate. The surface of push rod 6 is fixedly connected to the inner wall of push plate 7, and two push plates 7 are fixedly installed on the surface of each push rod 6; By pushing plate 7, the push rod 6 moves up and down and comes into contact with mounting plate 4, which can push the mounting plate to flip. The bottom end of the electric push rod 12 is fixedly connected to the center of the upper surface of the support plate 13, and the inner wall of the conversion block 8 is rotatably sleeved on the surface of the fixed rod 9. Working principle: When the operator drives the electric push rod 12, the electric push rod 12 can drive the movable rod 10 to rotate. When the movable rod 10 is controlled to rotate upward by the fixed sleeve 14, the movable rod 10, under force, pulls one side of the conversion block 8 to rotate relative to each other through the lever principle. During the rotation process, it is completed on the surface of the fixed rod 9. At the same time, the conversion block 8 also uses the lever principle to pull the push rod 6 and the push plate 7 to move upward, so that the push plate 7 abuts against the bottom of the mounting plate 4. Under the action of the rotating shaft 2, the mounting plate 4 is controlled to rotate upward, so that the roller 3 is in contact with the ground. The surface detaches, and the insert block is stably inserted into the ground, making the device more stable during operation. When the device needs to be moved, the electric push rod 12 is driven again to control the conversion block 8 to flip upward through the movable rod 10 via the lever principle. Under the lever action of the fixed rod 9, the connecting block controls the push rod 6 to flip downward on the outward side. Under the push of gravity and the push plate 7, the mounting plate 4 is flipped downward, so that the roller 3 simultaneously abuts against the ground, lifting the bottom of the moving frame 1 and pulling the insert rod 16 out of the ground, which facilitates the transfer of the device. Please see Figure 1-4 As shown, this embodiment is based on the above embodiment 1, with a sampling component. The sampling component includes a transparent protective frame 22, a sampling hole 23, a sampling rod 21, a threaded rod 20, a threaded sleeve, a transmission wheel 19, a drive wheel 17, a support frame 15, a servo motor 24, a support platform 18, a screw 26, and a nut 25. The surface of the transparent protective frame 22 is slidably fitted inside the movable frame 1. The sampling hole 23 is opened above the transparent protective frame 22. The surface of the sampling rod 21 is fitted inside the transparent protective frame 22. The top end of the sampling rod 21 is fixedly connected to the bottom end of the threaded rod 20. The surface of the threaded rod 20 is threadedly driven with the inner wall of the threaded sleeve. The surface of the threaded sleeve is fixedly installed on the inner wall of the transmission wheel 19. The surface of the transmission wheel 19 is meshed with the surface of the drive wheel 17. The lower end face of the support frame 15 is fixedly connected to the upper end face of the movable frame 1. The lower end face of the support frame 15 is fixedly connected to the upper end face of the servo motor 24. The output end of the servo motor 24 is fixedly installed on the lower end face of the drive wheel 17. The upper end face of the support platform 18 is fixedly installed on the lower end face of the support frame 15. During operation, the servo motor 24 can drive the drive wheel 17, which in turn drives the transmission wheel 19, so that the threaded sleeve can drive the threaded rod 20 through the threaded relationship between the threaded sleeve and the threaded rod 20, causing the threaded rod 20 to move up and down. At the same time, the threaded rod 20 drives the sampling rod 21 to drill into the formation to complete the sampling. The lower end face of the transmission wheel 19 is rotatably sleeved in the support platform 18, the lower end face of the drive wheel 17 is rotatably sleeved in the support platform 18, the surface of the threaded rod 20 penetrates the transparent protective frame 22, and the surface of the threaded rod 20 also penetrates the inner wall of the support frame 15. The bottom end of the screw 26 is fixedly connected to the upper end face of the transparent protective frame 22. The surface of the screw 26 is threaded with the inner wall of the nut 25. The lower end face of the nut 25 abuts against the upper end face of the movable frame 1. The transparent protective frame 22 prevents gravel from flying around and injuring workers when the sampling rod 21 is inserted into the concrete to take a sample. Working principle: When concrete blasting sampling is required, the drive wheel 17 rotates, and the drive wheel 17, through the meshing connection with the drive wheel 19, drives the nut 25 sleeve to drive the threaded rod 20 counterclockwise. At this time, the threaded rod 20 starts to control the sampling rod 21 to move downward towards the transparent protective frame 22 through the threaded connection. When the sampling rod 21 slides into the transparent protective frame 22 and blasts the concrete, the sampling process is completed. After completion, the servo motor 24 drives the drive wheel 17 again, and the drive wheel 17 drives the drive wheel 19 again. Through clockwise rotation, the threaded rod 20 and the sampling rod 21 are ensured to move upward. When the nut 25 is rotated counterclockwise to disengage from the screw 26, it is convenient to remove the transparent protective frame 22 upward and move the frame 1, which is convenient for concrete sampling.
