[0030] See also Figure 5-Figure 7 As shown, the clamping assembly includes a magnetic rail 11, a piston rod 111, a connecting spring 112, a fixing plate 113, a magnetic block 114, a cylinder 115 and a high temperature resistant airbag 116. Four high temperature resistant airbags 116 are fixedly connected to the inner side of the drill bit 8 at uniform intervals along the circumferential direction. When the high temperature resistant airbags 116 expand, the high temperature resistant airbags 116 can clamp and fix the core sample. The cylinder 115 is fixedly connected to the upper inner side of the drill bit 8. The bottom of the cylinder 115 is connected and communicated with the air inlet ends of the four high temperature resistant airbags 116. A piston rod 111 is slidably connected to the inner side of the cylinder body 115, and a fixed plate 113 is rotatably connected to the top of the piston rod 111. A connecting spring 112 is connected between the upper part of the piston rod 111 and the top of the drill bit 8. A magnetic block 114 is symmetrically fixed to the left side of the fixed plate 113. A magnetic track 11 is fixed to the left side of the bottom of the movable seat 1. A notch is provided on the upper left side of the magnetic track 11 for the magnetic block 114 to pass through. The magnetic track 11 slides through the movable seat 4, and the inner side of the magnetic track 11 is in magnetic contact with the magnetic blocks 114 on the front and rear sides.

[0031] First, the device is moved to the drilling sampling position through the movable seat 1, and then the driving motor 7 is started. The driving motor 7 drives the drill bit 8 to rotate through the synchronous belt assembly, and then the water is discharged into the water spray pipe 81. The water spray pipe 81 sprays water on the drill bit 8, and then the electric screw 3 is started to reverse and drive the movable seat 4 to move downward. The movable seat 4 drives the swing plate 5 to move downward, and the swing plate 5 drives the drill bit 8 to move downward. The drill bit 8 contacts the limit plate 9, and the limit plate 9 limits the drill bit 8 circumferentially. The drill bit 8 moves downward and drives the piston rod 111 to move downward through the cylinder body 115. The piston rod 111 drives the fixed plate 113 to move downward. The fixed plate 113 drives the magnetic block 114 to move downward and slide in the magnetic track 11. The drill bit 8 continues to move downward through the movable seat 1 and contacts the ground , the drill bit 8 drills into the ground to sample the core sample, and the sprayed water can prevent dust from appearing during the drilling process and can also cool the drill bit 8. When the core sampling is completed, the electric screw 3 is started to rotate forward to drive the movable seat 4 to move upward, and then the swing plate 5 drives the drill bit 8 to move upward. Since the magnetic track 11 attracts the magnetic block 114, the magnetic block 114 is limited, the magnetic block 114 limits the fixed plate 113, and the fixed plate 113 limits the piston rod 111. The drill bit 8 continues to move upward to compress the connecting spring 112, and the drill bit 8 drives the cylinder body 115 to move upward, and the piston rod 111 pushes the air in the cylinder body 115 into the high temperature resistant air bag 116. As the air is pushed in, the high temperature resistant air bag 116 continues to expand to clamp and fix the core sample. The core sample is prevented from falling into the hole in the ground during the resetting of the drill bit 8, so as to facilitate the collection of the taken core sample. Then the drill bit 8 continues to move upward and drives the core sample upward through the high temperature resistant air bag 116, and the magnetic block 114 moves upward and slides in the magnetic track 11. When the drill bit 8 is reset, the operator twists the knob 6 to reverse and drives the swing plate 5 to reverse, and the swing plate 5 reverses and drives the drill bit 8 to swing to the right. The drill bit 8 drives the fixed plate 113 to swing to the left through the piston rod 111, and the fixed plate 113 drives the magnetic block 114 to swing to the left and disengage from the magnetic track 11. Due to the action of the connecting spring 112, the piston rod 111 moves upward and resets through the fixed plate 113 to drive the magnetic block 114 to reset. The piston rod 111 also draws the air in the high temperature resistant air bag 116 back into the cylinder body 115. As the air is sucked away, the high temperature resistant airbag 116 continuously contracts and resets to loosen the core sample. At this time, the drill bit 8 swings to the right and contacts the contact wheel 101. The driving motor 7 controls the drill bit 8 to continuously rotate and drive the contact wheel 101 to reverse. The reverse rotation of the contact wheel 101 drives the rotating shaft 102 to reverse. The rotating shaft 102 drives the disc 103 to reverse. The disc 103 drives the trigger rod 104 to reverse and contact the fixed rod 108. The trigger rod 104 drives the fixed rod 108 to swing to the right. The fixed rod 108 drives the knocking frame 106 to swing to the right. The reset spring 107 is compressed, and the trigger rod 104 continues to reverse and disengages from the fixed rod 108. Due to the action of the reset spring 107, the knocking frame 106 swings to the left and resets to knock and vibrate the drill bit 8, and the drill bit 8 vibrates the taken out core sample.The core sample can be smoothly dropped from the drill bit 8 and collected without the need for knocking or vibrating with other tools, thereby improving the sampling efficiency. When the core sample drops from the drill bit 8, twisting the knob 6 drives the swing plate 5 to rotate forward and reset, and the swing plate 5 drives the drill bit 8 to swing left and reset, which also causes the magnetic block 114 to swing right and reset to contact the inner side of the magnetic track 11 again, and the drill bit 8 resets and disengages from the contact wheel 101, the contact wheel 101 stops reversing, and the knocking frame 106 stops swinging left and right. This is repeated to continuously drill and sample the core samples in road construction. When the core sampling is completed, turn off the drive motor 7 and the drill bit 8 stops rotating.

[0032] See also Figure 8 As shown, the device also includes an annular brush 12. The outer bottom of the movable seat 1 is rotatably connected to the annular brush 12. The annular brush 12 is located directly below the drill bit 8. When the drill bit 8 is reset, the annular brush 12 can remove impurities attached to the drill bit 8.

[0033] When the drill bit 8 moves downward to drill and sample, the drill bit 8 contacts the annular brush 12, and then after the drill bit 8 completes the drilling and sampling, the drill bit 8 moves upward to reset, and the annular brush 12 removes the impurities attached to the outer wall of the drill bit 8, and then the drill bit 8 continues to move upward to reset and disengage from the annular brush 12. In this way, a large amount of impurities attached to the outer wall of the drill bit 8 can be prevented from affecting subsequent use, thereby ensuring the subsequent use effect of the drill bit 8.

[0034] See also Fig. 9 As shown, the device also includes a material guide frame 13, which is fixedly connected to the middle of the right side of the movable seat 1. The material guide frame 13 is inclined. When the taken out core sample falls into the material guide frame 13, the material guide frame 13 can guide the core sample.

[0035] When the core sample falls from the drill bit 8, it falls into the guide frame 13, which guides and buffers the core sample so that the core sample rolls and is collected. In this way, the core sample can be prevented from falling violently to the collection point and breaking to affect subsequent detection, thereby ensuring the integrity of the core sample.

[0036] Finally, it is necessary to point out that the above content is only used to help understand the technical solution of the present invention and cannot be understood as limiting the scope of protection of the present invention; non-essential improvements and adjustments made by technical personnel in the field of technology based on the above content of the present invention are all within the scope of protection required by the present invention.
