[0027] The specific operation is as follows: after the staff fixes the sampling table 1 on the ground where the exploration sampling is needed, the second butt joint groove 504 at the top end of the drilling pile 501 is butt jointed with the mounting head 309, the first motor 301 drives the screw rod 302 to rotate, the sliding seat 303 can be adjusted in lifting through the sliding groove 2, which makes the sleeve seat 304 drive the rotating seat 305 and the mounting head 309 to be adjusted in height, and the drilling head 502 at the bottom end of the drilling pile 501 is in contact with the ground; at this time, the second motor 307 works, the meshing gear 308 drives the rotating seat 305 to rotate in the sleeve seat 304 through the meshing with the meshing gear slot 306, and the rotating seat 305 can drive the mounting head 309 to rotate synchronously in the rotating process, which makes the mounting head 309 drive the drilling pile 501 and the drilling head 502 to rotate, in the rotating process of the drilling pile 501, the screw rod 302 drives the sliding seat 303 to move downward, which can make the sleeve seat 304 drive the rotating seat 305 and the mounting head 309 to move downward synchronously, which makes the drilling head 502 can gradually drill into the soil layer, before the equipment is used for drilling and sampling, the staff can make the sampling head 605 pass through the through groove 310 and enter the second pair of through grooves 505 in the drilling pile 501, and make the sampling head 605 move to the bottom end of the second pair of through grooves 505, after the sampling head 605 moves to the bottom end of the second pair of through grooves 505, the sampling head 605 is electrified, the drilling pile 501 is made of magnetic metal material, which makes the sampling head 605 can be adsorbed and fixed with the drilling pile 501, in the drilling process, the drilling pile 501 can drive the sampling head 605 to rotate synchronously, the sampling head 605 and the sampling pipe 604 are connected with a rotatable pipe structure, so that the sampling head 605 will not interfere with the sampling pipe 604 in the rotating process, in addition, when the drilling pile 501 drills into the soil layer, the third motor 601 works, which can make the winding seat 602 wind the sampling pipe 604, which can avoid the influence of the length of the sampling pipe 604 on the sampling of the sampling head 605.

[0028] It needs to be explained that the surface of the winding seat 602 is provided with a groove consistent with the diameter of the sampling tube 604, and the wall thickness of the sampling tube 604 is relatively thick, which can ensure that the sampling tube 604 will not be deformed due to extrusion when being wound at the outer end of the winding seat 602, thereby affecting the occurrence of the soil sampling condition. In the process of drilling and digging by the drilling and digging head 502, the suction pump 615 works to enable the suction force to be transmitted to the sampling tube 604 through the collection box 612, the inlet pipe 611, the rotating pipe 610, and the rotating adapter 603. At this time, the sampling head 605 controls the first electric control valve 607 to be opened and the second electric control valve 609 to be closed, which enables the suction force to be transmitted to the inside of the second pair of through grooves 505 through the first collection groove 606. The second pair of through grooves 505 are communicated with the soil discharge groove 503, which enables the soil drilled and dug by the drilling and digging head 502 to be sucked into the second pair of through grooves 505 and then into the sampling tube 604 through the sampling head 605. The soil in the sampling tube 604 can enter the collection box 612 for storage through the rotating adapter 603, the rotating pipe 610, and the inlet pipe 611. The collection box 612 is provided with the blocking net 613 at the inside bottom end, which can prevent the soil from entering the inside of the suction pump 615. At this time, the staff can open the airtight door 614 to realize the collection of the soil sample. In the above operation process, the suction structure is adopted to collect the soil sample, which can avoid the traditional soil sample collection when the equipment is stopped and the soil in the drilling pit is manually collected after drilling to the specified depth, which can greatly improve the efficiency and convenience of sample collection. In addition, the suction structure can realize real-time cleaning of the floating soil while collecting the soil, which can avoid the accumulation of floating soil in the drilling hole to affect the normal drilling of the drilling and digging head 502.

[0029] Please refer to Figures 1 to 11 The pile assembly 4 includes a U-shaped pile 401, a first pair of connecting grooves 402 are formed in the top inner side of the U-shaped pile 401, and an adapter pile 403 is arranged at the bottom end of the U-shaped pile 401. A first pair of through grooves 404 are formed in the inner side of the U-shaped pile 401, and a clamping groove 405 is formed in the inner wall of the U-shaped pile 401. A connecting pile 406 is arranged at the outer end of the U-shaped pile 401, and elastic clamping blocks 407 are arranged on both sides of the inside of the connecting pile 406. An air passage 408 is formed in the inside of the connecting pile 406, and a reset spring 409 is arranged in the inside of the connecting pile 406. A columnar seat 410 is arranged at the outer end of the reset spring 409, and a first pair of through holes 411 are formed in the side of the columnar seat 410 close to the air passage 408. A second pair of through holes 412 are formed at the top end of the columnar seat 410. A first meshing tooth 413 is arranged at the top of the columnar seat 410, and a driven gear 414 is arranged at the top outer end of the columnar seat 410. A collection seat 415 is arranged at the top outer end of the driven gear 414, and a second meshing tooth 416 is arranged at the bottom end of the collection seat 415. The bottom outer end of the collection seat 415 is provided with a third pair of through openings 417, and the outer end of the collection seat 415 is provided with a collection head 418, the inner side of the collection head 418 is provided with a suction groove 419, the inside of the U-shaped pile 401 is provided with a permanent magnet block 420, the sampling pipe 604 is connected with the rotating pipe 610 through the rotating adapter 603, and the sampling pipe 604 is communicated with the first collection groove 606 and the second collection groove 608, the outer contour size of the sampling head 605 matches the size of the first pair of through grooves 404 and the second pair of through grooves 505, the first collection groove 606 is communicated with the soil discharge groove 503 through the second pair of through grooves 505, the second collection groove 608 is communicated with the columnar seat 410 through the air groove 408 and the first pair of through openings 411, the columnar seat 410 is communicated with the third pair of through openings 417 through the second pair of through openings 412, the third pair of through openings 417 are communicated with the suction groove 419, the first pair of through openings 411 is displaced to drive the driven gear 414 to rotate through the first engagement tooth 413, the driven gear 414 is engaged with the second engagement tooth 416, the sampling head 605 is electromagnetically adsorbed and connected with the drilling pile 501 through the electromagnet 616, and the sampling head 605 is electromagnetically adsorbed and connected with the permanent magnet block 420 through the electromagnet 616.

[0030] It can be understood that after the drilling pile 501 is completely drilled into the soil layer, the sliding seat 303 is driven to move up by the lead screw 302, so that the mounting head 309 is separated from the drilling pile 501, after the sliding seat 303 drives the mounting head 309 to move back to the top end, the worker aligns the opening of the U-shaped pile 401 with the sampling pipe 604, so that the U-shaped pile 401 surrounds the outer end of the sampling pipe 604, the opening surface of the U-shaped pile 401 is inclined, the worker aligns the elastic clamping block 407 of the butt joint pile 406 with the clamping groove 405 of the U-shaped pile 401 and presses down, so that the elastic clamping block 407 is clamped into the clamping groove 405, at this time, the U-shaped pile 401 and the butt joint pile 406 are combined as a whole, and at the same time in the process of butt joint, the sampling pipe 604 is arranged in the inside, at this time, the worker inserts the adapter pile 403 at the bottom of the U-shaped pile 401 into the second butt joint groove 504 at the top of the drilling pile 501, so as to realize the butt joint of the U-shaped pile 401 and the drilling pile 501; Meanwhile, the screw rod 302 drives the sliding seat 303 to move downward, so that the mounting head 309 is connected with the first connecting groove 402 at the top of the U-shaped pile 401. Through the design, the device can make the drill head assembly 5 enter deeper soil layer for exploration by adding the pile body assembly 4, and the combined design of the U-shaped pile 401 and the connecting pile 406 makes it unnecessary to take out the sampling head 605 during the process of adding the pile body, which greatly improves the convenience of adding the pile body. In addition, the sampling members are located in the connecting pile 406, so that the staff can detect the sampling members in the connecting pile 406 before connecting the U-shaped pile 401 and the connecting pile 406, to determine whether the sampling members are damaged. If the sampling members are damaged, the staff only needs to replace the spare connecting pile 406 to quickly solve the problem, thereby effectively reducing the failure rate of the device.

[0031] In addition, it should be noted that the bottom end of the elastic clamping block 407 is a chamfered surface. When the staff separates the U-shaped pile 401 and the connecting pile 406, the staff only needs to push the connecting pile 406 downward, so that the elastic clamping block 407 slides downward through the chamfered surface to separate from the U-shaped pile 401. Through the design, the connection and separation of the U-shaped pile 401 and the connecting pile 406 can be facilitated. When the electromagnet 616 loses power, the sampling head 605 is in a locked contact with the drilling pile 501. At this time, the third motor 601 drives the winding seat 602 to wind, so that the sampling head 605 moves upward. After the sampling head 605 moves to the inside of the U-shaped pile 401, the electromagnet 616 is powered again. The U-shaped pile 401 and the connecting pile 406 are made of non-magnetic metal, so the sampling head 605 will not be attracted to the U-shaped pile 401 and the connecting pile 406. When the sampling head 605 moves to the position where the electromagnet 616 and the permanent magnet 420 are at the same height, the electromagnet 616 can be inducted by the permanent magnet 420. The electromagnet 616 and the permanent magnet 420 are both provided with two groups, and each group is provided with a positive electrode and a negative electrode. This makes the sampling head 605 rotate to the position where the two groups of electromagnets 616 and permanent magnets 420 are attracted due to the magnetic force. Through the design, the height and direction of the sampling head 605 can be accurately controlled. When the sampling head 605 is located at the position where the two groups of electromagnets 616 and permanent magnets 420 are attracted, the second collecting groove 608 is connected with the ventilation groove 408. At this time, the sampling head 605 controls the second electric control valve 609 to be opened, the first electric control valve 607 to be closed, and the suction pump 615 to work, so that the suction force enters into the ventilation groove 408 through the second collecting groove 608, and enters into the cylindrical seat 410 through the first connecting port 411. Under the influence of the suction force, the cylindrical seat 410 is pressed to move to the direction of the ventilation groove 408.

[0032] It should be noted that in the process of displacement of the columnar seat 410, the driven gear 414 can be driven to rotate by the first meshing teeth 413, and in the process of rotation of the driven gear 414, the collection seat 415 can be driven to displace outward by the meshing of the second meshing teeth 416, which makes the collection head 418 able to extend out to contact the soil layer of the inner wall of the hole with the pile 406, at this time the second motor 307 works, which can make the pile body assembly 4 rotate, which makes the collection head 418 can collect the soil layer of the inner wall of the hole, the displacement of the collection seat 415 will make the third pair of through holes 417 and the second pair of through holes 412 of the columnar seat 410 communicate, which makes the suction force enter into the suction groove 419 inside through the third pair of through holes 417, which makes the device can collect the soil sample collected by the collection head 418, through the operation, the device can still collect the soil sample after drilling to the deeper soil layer, which can avoid the situation that the soil sample is confused and needs to be re-explored.

[0033] When using the sampling device for geological exploration, first, the staff fixes the sampling table 1 on the ground that needs to be explored and sampled, and then the second interface groove 504 at the top of the drilling pile 501 is docked with the mounting head 309. The first motor 301 drives the screw rod 302 to rotate, which can make the sliding seat 303 adjust the lifting through the sliding groove 2, which makes the sleeve seat 304 drive the rotating seat 305 and the mounting head 309 to adjust the height, and makes the drilling head 502 at the bottom of the drilling pile 501 contact with the ground. At this time, the second motor 307 works, which can make the meshing gear 308 drive the rotating seat 305 to rotate in the sleeve seat 304 through the meshing with the meshing tooth groove 306, and the rotating seat 305 can drive the mounting head 309 to rotate synchronously in the process of rotation, which makes the mounting head 309 drive the drilling pile 501 and the drilling head 502 to rotate. In the process of rotation of the drilling pile 501, the screw rod 302 drives the sliding seat 303 to move downward, which can make the sleeve seat 304 drive the rotating seat 305 and the mounting head 309 to move downward synchronously, which makes the drilling head 502 gradually drill into the soil layer; Then, before drilling and sampling, the staff can pass the sampling head 605 through the slot 310 into the second pair of slots 505 of the drilling pile 501, and move the sampling head 605 to the bottom of the second pair of slots 505. After the sampling head 605 moves to the bottom of the second pair of slots 505, the sampling head 605 is powered on, and the drilling pile 501 is made of magnetic metal material, which enables the sampling head 605 to be adsorbed and fixed with the drilling pile 501. During drilling, the drilling pile 501 can drive the sampling head 605 to rotate synchronously. The joint between the sampling head 605 and the sampling tube 604 adopts a rotatable tube structure, so that the sampling head 605 will not interfere with the sampling tube 604 during rotation. In addition, when the drilling pile 501 drills into the soil layer, the third motor 601 works to make the winding seat 602 unwind the sampling tube 604, which can avoid the influence of the length of the sampling tube 604 on sampling. In addition, the winding seat 602 is provided with a groove with the same diameter as the sampling tube 604, and the sampling tube 604 has a relatively thick wall, which can ensure that the sampling tube 604 will not be deformed due to extrusion when it is wound around the outer end of the winding seat 602, thereby avoiding the occurrence of soil sampling problems. During drilling, the suction pump 615 works to make the suction force pass through the collection box 612, the inlet pipe 611, the rotating pipe 610, and the rotating adapter 603 to the sampling tube 604; Then, the sampling head 605 controls the first electric control valve 607 to open and the second electric control valve 609 to close, which enables the suction force to pass through the first collection groove 606 to the inside of the second pair of slots 505. The second pair of slots 505 are connected with the soil discharge groove 503, which enables the soil drilled by the drilling head 502 to be sucked into the second pair of slots 505 through the soil discharge groove 503, and then into the sampling tube 604 through the sampling head 605. The soil in the sampling tube 604 can enter the collection box 612 through the rotating adapter 603, the rotating pipe 610, and the inlet pipe 611 for storage. The inside bottom end of the collection box 612 is provided with a blocking net 613, which can prevent the soil from entering the suction pump 615. At this time, the staff can open the airtight door 614 to realize the collection of the soil sample. In the above operation process, the suction structure is used to collect the soil sample, which can avoid the need to pause the equipment and manually collect the soil in the drilling pit when drilling to the specified depth in the traditional soil sample collection process, which can greatly improve the efficiency and convenience of sample collection. In addition, the suction structure can also clean the floating soil in real time while collecting the soil, which can avoid the accumulation of floating soil in the drilling hole and affect the normal drilling of the drilling head 502; Subsequently, after the drilling pile 501 is completely drilled into the soil layer, the screw rod 302 drives the sliding seat 303 to move upwards, so that the mounting head 309 is separated from the drilling pile 501, and after the sliding seat 303 drives the mounting head 309 to move back to the top end, the worker aligns the opening of the U-shaped pile 401 with the sampling pipe 604, so that the U-shaped pile 401 surrounds the outer end of the sampling pipe 604, the opening surface of the U-shaped pile 401 is inclined, and the worker aligns the elastic clamping block 407 of the butt pile 406 with the clamping groove 405 of the U-shaped pile 401 and presses it down, so that the elastic clamping block 407 is clamped into the clamping groove 405, and at this time the U-shaped pile 401 and the butt pile 406 are combined into a whole, and at the same time in the process of butt joint, the sampling pipe 604 is arranged in the inside, at this time the worker inserts the connecting pile 403 at the bottom end of the U-shaped pile 401 into the second butt joint groove 504 at the top end of the drilling pile 501, so as to realize the butt joint of the U-shaped pile 401 and the drilling pile 501, and at the same time the screw rod 302 drives the sliding seat 303 to move downwards, so that the mounting head 309 is butt jointed with the first butt joint groove 402 at the top end of the U-shaped pile 401, through the design, the equipment can make the drill head assembly 5 enter deeper soil layer for exploration by adding the pile body assembly 4; Through the combined design of the U-shaped pile 401 and the butt pile 406, the equipment does not need to take out the sampling head 605 during the process of adding the pile body, which can greatly improve the convenience of the equipment for adding the pile body, in addition, the sampling members are located in the butt pile 406, and the worker can detect the sampling members in the butt pile 406 before butt joint of the U-shaped pile 401 and the butt pile 406, to judge whether the sampling members are damaged, if the sampling members are damaged, the worker only needs to replace the spare butt pile 406 to quickly solve the problem, through the modular design, the failure rate of the equipment can be greatly reduced, in addition, the bottom end of the elastic clamping block 407 is chamfered, when the worker separates the U-shaped pile 401 and the butt pile 406, only needs to push the butt pile 406 downwards, the elastic clamping block 407 can slide downwards through the chamfered surface to realize the separation from the U-shaped pile 401, through the design, the butt joint and separation of the U-shaped pile 401 and the butt pile 406 can be facilitated; Finally, the electromagnet 616 loses power, which can make the sampling head 605 in locking contact with the drilled pile 501, at this time, the third motor 601 drives the winding seat 602 to wind, which can make the sampling head 605 move up, after the sampling head 605 moves up to the inside of the U-shaped pile 401, the electromagnet 616 is powered again, the U-shaped pile 401 and the butt pile 406 are made of non-magnetic metal, so the sampling head 605 will not be adsorbed with the U-shaped pile 401 and the butt pile 406, and when the sampling head 605 moves to the position where the electromagnet 616 and the permanent magnet block 420 are at the same height, the electromagnet 616 can be inducted with the permanent magnet block 420, both the electromagnet 616 and the permanent magnet block 420 are provided with two groups, and both groups are arranged with one positive and one negative, which makes the sampling head 605 rotate to the position where the two groups of electromagnet 616 and permanent magnet block 420 are adsorbed due to magnetic force, through this design, the height and direction of the sampling head 605 can be accurately controlled, when the sampling head 605 is located at the position where the two groups of electromagnet 616 and permanent magnet block 420 are adsorbed, the second collection groove 608 will be in communication with the ventilation groove 408, at this time, the sampling head 605 controls the second electric control valve 609 to open, the first electric control valve 607 to close, and the suction pump 615 to work, which can make the suction force enter into the ventilation groove 408 through the second collection groove 608; And through the first pair of through holes 411 into the columnar seat 410, under the influence of the suction force, the columnar seat 410 will extrude the return spring 409 to displace in the direction of the ventilation groove 408, and in the process of displacement of the columnar seat 410, the driven gear 414 can be driven to rotate through the first meshing teeth 413, and in the process of rotation of the driven gear 414, the collection seat 415 can be displaced outward through the meshing with the second meshing teeth 416, which makes the collection head 418 can be extended to contact the soil layer of the inner wall of the pit with the butt pile 406, at this time, the second motor 307 works, which can make the pile body assembly 4 rotate, which makes the collection head 418 can collect the soil layer of the inner wall of the pit, after the displacement of the collection seat 415, the third pair of through holes 417 will be in communication with the second pair of through holes 412 of the columnar seat 410, which makes the suction force enter into the suction groove 419 through the third pair of through holes 417, which makes the device can collect the soil sample collected by the collection head 418, through this operation, the device can still collect the soil sample after drilling to a deeper soil layer, which can avoid the situation that the soil sample is mixed and needs to be re-explored.
