[0045] The working principle of the present invention is:

[0046] When the posture adjustment component is working: the piston rod of the hydraulic cylinder 201 drives the position adjustment frame 301 to rotate on the hinge seat 202, thereby adjusting the posture of the position adjustment frame 301, and adjusting the postures of the first position adjustment component, the first position adjustment component, the driving component, the drilling unit, the sampling unit, the clamping mechanism and the cooling unit through the position adjustment frame 301, thereby facilitating transportation while reducing the overall space occupied, improving the convenience during use, and greatly reducing the use cost and the workload of the operator; the various postures are respectively as follows Figure 1 , Figure 5 , Figure 6 and Figure 7 shown.

[0047] When the first position adjustment component is working: the output shaft of the motor 302 drives the screw 304 to rotate, and when the screw 304 rotates, it drives the position adjustment frame 2 401 to slide on the guide rod 306 and the position adjustment frame 1 301 through the slide 402, thereby changing the position of the second position adjustment component, and then changing the position of the driving component, the drilling unit, the sampling unit, the clamping mechanism and the cooling unit.

[0048] When the second position adjustment component and the driving component are working: the output shaft of the second motor 405 drives the second screw 403 to rotate, and when the second screw 403 rotates, it drives the driving frame 410 to slide on the second position adjustment frame 401, and when the second screw 403 slides, the first pulley 407 slides on the spline shaft 404, thereby adjusting the positions of the driving component, the drilling unit, the sampling unit, the clamping mechanism and the cooling unit; when the output shaft of the third motor 406 drives the spline shaft 404 to rotate, the spline shaft 404 drives the first pulley 407 to rotate, the first pulley 407 drives the second pulley 408 to rotate through the belt 409, and the second pulley 408 drives the drilling tube 501 to rotate through the connecting tube 502, and at the same time, the drilling tube 501 is driven to move under the action of the movement of the driving frame 410, and the drilling tube 501 drives the sampling tube 504 to move, so as to facilitate drilling and sampling through the drilling tube 501 and the sampling tube 504.

[0049] When the drilling unit, sampling unit, clamping mechanism and cooling unit are working: the drilling cylinder 501 rotates and descends at the same time, the drilling cylinder 501 drills the cement mixing pile after the pile is formed through the drill bit 513, and the cement mixing pile sample after the pile is formed enters the drilling cylinder 501 and the sampling cylinder 504 through the drill bit 513. When the sample passes through the clamping block 506, the clamping block 506 rotates under the action of the extrusion force, and the spring 505 and the torsion spring 507 are deformed; during the drilling sampling At the same time, the cooling water is injected into the cooling chamber 1 508 through the water inlet hole 515 by the cooling water injection device, enters the cooling channel 1 510 through the cooling chamber 1 508, passes through the cooling channel 1 510, the cooling channel 2 511, and the cooling chamber 2 512, and then flows out of the water outlet 514, thereby effectively cooling the drilling tube 501, the sampling tube 504, and the drill bit 513, and the cooling water can be used to the greatest extent, avoiding the large amount of cooling water flowing out and causing Waste; when the specified sampling depth is reached (the sampling depth is determined according to the actual sampling), the motor 2 405 stops working, and the driving frame 410 stops descending, and the drilling tube 501 and the sampling tube 504 stop descending. At this time, under the action of the elastic force of the spring 505 and the torsion spring 507, multiple clamping blocks 506 are driven to clamp the sample, and the drilling tube 501 and the sampling tube 504 continue to rotate. Under the action of the clamping force, the sample is twisted off, so that the sample is separated from the cement mixing pile body, and then the motor 2 405 rotates in the opposite direction to drive the driving frame 410 to rise, and the motor 3 406 stops working, so that the drilling tube 501 and the sampling tube 504 stop rotating. When the driving frame 410 rises, it drives the drilling tube 501, the connecting tube 502, and the sampling tube 504 to rise. Due to the clamping force of the spring 505 and the torsion spring 507, it can be ensured that the sample will not fall off under the action of gravity, and then the sample is taken out from the cement mixing pile, thereby completing the sampling of the cement mixing pile.

[0050] If the depth of the sample is deeper (the depth is determined according to actual use), the second position adjustment component is adjusted to the side close to the hydraulic cylinder 201 through the first position adjustment component, thereby lengthening the position adjustment frame 401 to the height of the cement mixing pile, and then replacing the connecting tube 502 with a longer size (the length is determined according to actual use), and then with the cooperation of the first position adjustment component and the second position adjustment component, cement mixing piles of different depths can be sampled. The sampling range is larger and it will not take up a large space, which further improves the convenience of sampling.

[0051] After the sampling is completed, the postures of the first position adjustment component, the first position adjustment component, the drive component, the drilling unit, the sampling unit, the clamping mechanism and the cooling unit are adjusted through the posture adjustment component to a posture that is convenient for the operator to take out the sample (the adjusted posture is determined according to actual use). After the adjustment is completed, the cement mixing pile sample obtained from the drilling tube 501, the sampling tube 504, the connecting tube 502 and the cooling tube 503 are pushed out by one side of the water outlet 514. During the pushing, the clamping block 506 can be rotated, which makes it easier and faster to push out the sample, thereby greatly improving the sampling efficiency.

[0052] After sampling is completed, the cement mixing pile samples are numbered and stored, and then sent to the testing point for testing.
