Description

Technical Field

[0001] The present invention relates to the technical field of frozen soil sampling and shaping, and in particular to a temperature-controlled non-disturbing conical frozen soil sampling and shaping device with a salt thermal power cone arc knife. Background Technique

[0002] In the northern cold and arid irrigation areas, due to the large water content in the channels in winter, the freezing state is complex, and strong freezing leads to a large range of frost heave deformation and different deformation laws, resulting in frost heave damage to irrigation channels. The main manifestations are the reduction of the anti-seepage performance of the channels caused by the frost heave deformation of the foundation soil and the damage of the regional lining structure. Therefore, in order to better design and anti-frost heave protection for the channels, ensure the long-term stable service of the channels, improve the anti-seepage ability of the channels, and extend the service life of the channel lining, it is necessary to understand in detail the development law of the freezing and frost heave deformation of the soil at the channel bottom under actual working conditions. In practice, due to the layered and disordered distribution of soil-ice in the channel, the vulnerability is relatively large under the strong freezing state. This requires accurate in-situ sampling of frozen soil columns in a non-disturbed state as much as possible to ensure the accuracy of test data.

[0003] At present, when conducting in-situ sampling operations of frozen soil in the wild, various inconveniences and limitations that are difficult to overcome are often faced. First of all, due to the complexity and variability of the winter environment of field irrigation channels, the soil sampling operation is often affected by various factors such as terrain, climate, soil properties, and human factors. The most important one is that it is greatly affected by the sampling equipment. During the frozen soil sampling process, it is inevitable to be disturbed, which destroys the internal structural characteristics of the frozen soil. Currently, the common method of frozen soil sampling is to manually operate a ring knife and a cylindrical drill for sampling.

[0004] Although the traditional ring knife soil sampling method can meet the soil sampling requirements for soils with relatively small water content and non-frozen state, its limitations are also obvious. On the one hand, the ring knife is not suitable for frozen soil. It is difficult to take soil with a ring knife in frozen soil with high water content. The sampling depth is relatively small, and it is difficult to extract after the ring knife is pressed or hammered in. Moreover, after the ring knife is pressed into the frozen soil, the metal quickly cools down, and the ring knife freezes together with the soil, making it difficult to extract. On the other hand, the ring knife causes relatively large disturbance to the frozen soil during the process of being forced to press or hammer into the soil. The ring knife soil sampling causes great damage to the soil structure in the frozen state. Especially when the sampling point is relatively deep, it is easy to damage the pore structure of the soil, thus affecting the physical and mechanical properties of the soil.

[0005] In addition, the method of using a cylindrical drill to take soil samples from frozen soil is currently relatively common. The drill bit takes soil by rotating the drill bit to cut the soil, which has the characteristics of high efficiency and flexibility, and can significantly improve the soil sampling efficiency. However, there are also certain limitations in taking soil with a drill bit. Since the cylindrical drill bit rotates at a high speed during the process of cutting frozen soil, it will generate relatively large vibrations and impact forces, causing certain disturbances to the soil, including but not limited to irregular shapes of soil columns. And in the state of relatively low environmental temperature in winter, during the process of taking soil, inevitable drill stoppage will cause the drill bit to freeze with the soil body and be difficult to separate, resulting in sampling failure. In addition, taking soil with a drill bit has relatively high requirements for the moisture content of the soil. Too wet or too dry soil may lead to poor soil sampling effects. When using a drill bit to take soil, it is necessary to select and adjust according to the specific conditions of the soil. And during the process of taking soil with a drill bit, due to the high-speed rotation of the drill bit and the friction with the soil body or ice body, a large amount of heat is generated, resulting in the melting-freezing of the ice body radiated from the surface layer of the soil body to the center and the occurrence of moisture migration, etc., and the original appearance of the soil body cannot be truly restored. Due to the natural limitations of the cylindrical drill bit of the drill rig, the bottom of the frozen soil sample column is still adhered to the matrix. In actual operation, a crowbar is usually used to pry the side wall to make the bottom break. Due to the relatively large water content of the soil in the channel, obvious stratification of water-ice soil, and non-uniform distribution of the fragile surfaces of the soil column, this kind of prying operation often leads to a relatively large randomness of the actual fracture position, and after being subjected to external force, microcracks are generated inside the soil body, which has a greater impact on the subsequent test process. For this reason, we have developed a salt thermal power cone arc knife temperature-controlled non-disturbing conical frozen soil sampling and shaping device. Summary of the Invention

[0035] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention extracts a conical original soil mass with a wider top and a narrower bottom through the seepage cutting tool assembly, avoiding the disturbance of the conical original soil mass by the arc-shaped seepage knife. During the cutting process, the cutting edge part of the arc-shaped seepage knife is electrically heated and a salt solution seepage operation is carried out on the cutting surface, reducing the cutting energy consumption and the stress on the sample at the same time. Moreover, the bottom of the conical original soil mass with a wider top and a narrower bottom is cut thoroughly without adhesion.

[0036] The morphology of the conical original soil mass is reorganized. Under the temperature and humidity environmental conditions at the time of soil sampling, in-situ soil is used for filling, and an airbag is used to tamp the in-situ soil filling, so as to realize the shaping of the conical original soil mass into a cylindrical soil sample, so as to eliminate the internal stress during subsequent cutting and maintain the original frozen structure of the original soil mass. And an airbag is used in cooperation with an internal traction wire for limited tamping, realizing the freezing and tamping of the in-situ soil without disturbing the original conical original soil mass, avoiding the influence of oblique stress generated by the inclined contact between the cutting tool and the cutting surface during the cutting process on the internal crack distribution.

[0037] Compared with ordinary ring cutters, the present invention uses a cutting tool with variable diameter and high-frequency vibration to gradually move up and down to strip frozen soil, and combines a displaceable cutting tool to achieve a variable-size circumcision process. A cavity is formed on the fitting surface between the cutting tool and the cylinder, which can quickly cool the cavity during cutting; the cutting edge of the cutting tool adopts an electric heating strategy during up and down cutting to achieve a rapid transition from the melting state of the cutting point to the cooling state of the cutting surface, avoiding the disturbance of the soil core sample caused by stress transfer during cutting and the influence of heat transfer on the soil structure. Secondly, the rapid vibration of the cutting tool can achieve flexible cutting of the soil layer by layer, greatly retaining the natural frozen structure of the original soil.

[0069] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0070] Embodiment:

[0071] Please refer to Figures 1 - 24 , the present invention provides a technical solution:

[0072] The present invention is applicable to an integrated device for non-disturbingly preparing and cutting and shaping frozen soil samples of canal base soil in a high water content state in northern irrigation channels. Through step-by-step cutting and shape restructuring, a salt thermal power conical knife is used to realize resistance heating and salt infiltration cutting to separate the soil body; then, the original soil is used for secondary limit freezing, and a variable conical barrel-shaped airbag is used for ramming to change the shape of the soil sample to avoid stress concentration inside the soil sample during the cutting process; high-frequency rapid freezing and thawing circular cutting is used to obtain frozen soil samples. The purpose of the present invention is to restore the natural structure of the frozen soil, avoid disturbing the soil body during the process of preparing the soil sample, reduce the labor cost and the influence of human factors, and provide a real scene restoration for subsequent scientific research.

[0073] A temperature-controlled non-disturbing conical frozen soil sampling and shaping device with a salt thermal power conical arc knife, comprising a mobile equipment box 1 and a global control module 2, a shaping mechanism 3, a primary cutting module 4, a secondary cutting module 5 and a transportation and hoisting module 6 arranged on the mobile equipment box 1;

[0074] The global control module 2 is used to control the working of the shaping mechanism 3, the primary cutting module 4, the secondary cutting module 5 and the transportation and hoisting module 6 respectively. The global control module 2 includes a display fixed on the side of the mobile equipment box 1 and a PLC controller built in the display.

[0075] As Figure 1 and 2 shown, the primary cutting module 4 is arranged in the middle of the bottom plate 106, the shaping mechanism 3 and the secondary cutting module 5 are respectively arranged on the left and right sides of the bottom plate 106, and the primary cutting module 4 is located between the shaping mechanism 3 and the secondary cutting module 5.

[0076] A fourth electric cylinder 104 is provided at the bottom of the bottom plate 106, and the bottom output end of the fourth electric cylinder 104 is connected with a moving wheel 105; the PLC controller controls the piston rod of the output end of the fourth electric cylinder 104 to extend, so as to lift the height of the mobile equipment box 1, and prevent the bottoms of the primary cutting module 4, the shaping mechanism 3 and the secondary cutting module 5 from contacting the ground when moving through the moving wheel 105.

[0077] The primary cutting module 4 includes a rotating component connected to the bottom plate 106 at the bottom of the mobile equipment box 1, a seepage cutting tool component connected to the bottom of the rotating component, and a salt solution pipeline system for discharging salt solution through the arc-shaped seepage knife 409 of the seepage cutting tool component;

[0078] As Figure 2 、 9 and 10 shown, the rotating component includes a top ring seat 405 fixed on the bottom plate 106, an outer ring seat 401 connected to the lower end of the top ring seat 405 by a connecting column 403, a third motor 402 fixed at the upper end of the outer ring seat 401, and an inner ring seat 404 slidably buckled inside the outer ring seat 401;

[0079] The first drive gear 412 at the output end of the third motor 402 meshes with the toothed ring seat 413 at the upper end of the inner ring seat 404. The PLC controller controls the operation of the third motor 402, so that the first drive gear 412 drives the inner ring seat 404 to rotate inside the outer ring seat 401 through the toothed ring seat 413. In this way, when the arc-shaped seepage cutter 409 extends to the state as shown in Figure 9 When shown, the rotation of the inner ring seat 404 can drive the seepage cutting tool assembly at its bottom to rotate and cut the original soil body.

[0080] As Figure 11 , 12 As shown in and 13, the arc-shaped seepage cutter 409 of the seepage cutting tool assembly is telescopically arranged. The seepage cutting tool assembly includes arc-shaped seepage cutter seats 408 fixed at equal intervals at the bottom of the inner ring seat 404 by connecting frames 406, upper and lower groups of I-shaped sliders 416 slidably connected in the slots 4081 in the middle of the arc-shaped seepage cutter seats 408, connecting plates 410 connected between the upper and lower groups of I-shaped sliders 416, and fourth motors 415 fixed outside the I-shaped sliders 416;

[0081] The upper part of the arc-shaped seepage cutter 409 is fixed to the inner walls of the upper and lower groups of I-shaped sliders 416;

[0082] A second drive gear 417 is fixed to the rotating shaft 418 inside the I-shaped slider 416, and a motor gear meshing with the inner side of the second drive gear 417 is provided at the output end of the fourth motor 415;

[0083] A U-shaped chute 4161 slidably connected to the inner wall of the slot 4081 is provided on the side of the I-shaped slider 416;

[0084] The PLC controller controls the operation of the fourth motor 415, so that the motor gear drives the second drive gear 417 to rotate. Since the outer side of the second drive gear 417 extends into the U-shaped chute 4161 and meshes with the teeth on the inner wall of the slot 4081, when the second drive gear 417 rotates, the upper and lower groups of I-shaped sliders 416 and the connecting plate 410 as a whole move up and down along the slot 4081, thereby driving the arc-shaped seepage cutter 409 to move up and down along the arc-shaped seepage cutter seat 408 to realize the telescoping of the arc-shaped seepage cutter 409.

[0085] When the arc-shaped seepage cutter 409 extends downward along the arc-shaped seepage cutter seat 408 to the state as shown in Figure 9 When shown, the bottom of the arc-shaped seepage cutter 409 is inserted into the original soil body. Subsequently, through the rotation of the inner ring seat 404 of the rotating assembly, the arc-shaped seepage cutter 409 at the bottom of the inner ring seat 404 rotates and cuts the original soil body to obtain a conical original soil body block 8.

[0086] As Figure 1 , 9As shown in FIGS. 9 and 10, the brine pipeline system includes an upper liquid guide pipe 411 communicating between a brine tank 101 at the top of the mobile equipment box 1 and an outer ring seat 401, and a lower liquid guide hose 407 communicating between an inner ring seat 404 and an arc-shaped seepage cutter 409;

[0087] The upper liquid guide pipe 411 and the lower liquid guide hose 407 are communicated through an annular groove 414 between the outer ring seat 401 and the inner ring seat 404;

[0088] As Figure 13 shown, a plurality of groups of liquid outlet holes 4091 distributed up and down are provided on the inner side surface of the arc-shaped seepage cutter 409, and the liquid outlet holes 4091 are communicated with the bottom of the lower liquid guide hose 407 through a channel inside the arc-shaped seepage cutter 409.

[0089] The brine in the brine tank 101 enters the annular groove 414 between the outer ring seat 401 and the inner ring seat 404 through the upper liquid guide pipe 411, and is discharged through the lower liquid guide hose 407 and the channel inside the arc-shaped seepage cutter 409 through the liquid outlet holes 4091. In this way, when the arc-shaped seepage cutter 409 rotates and cuts the original soil mass, the brine contacts the surface of the conical original soil mass block 8, which can prevent the cut conical original soil mass block 8 from freezing and adhering to the original soil mass.

[0090] And an electric heating wire is built in the cutting edge of the arc-shaped seepage cutter 409. The rotating assembly drives the seepage cutting tool assembly to rotate, and the original soil mass is cut through the arc-shaped seepage cutter 409 to obtain a conical original soil mass block 8;

[0091] During the cutting process, the cutting edge of the arc-shaped seepage cutter 409 is heated by energizing the electric heating wire, which can also prevent the cut conical original soil mass block 8 from freezing and adhering to the original soil mass.

[0092] The shaping mechanism 3 includes a barrel body 302 connected to the bottom plate 106, a barrel cover assembly for sealing the top of the barrel body 302, and an airbag 309 arranged on the barrel cover assembly. After the airbag 309 is inflated, it is used to extrude, tamp and freeze the conical original soil mass block 8 and the in-situ soil filling 7 placed inside the barrel body 302, and a shaped columnar soil sample is obtained;

[0093] As Figure 3 and 4 shown, the barrel cover assembly includes a rotating shaft 307 movably connected between two groups of front and rear inverted U-shaped cross frames 107, a fifth motor 308 fixed on the inverted U-shaped cross frame 107 for driving the rotating shaft 307, and a barrel cover 301 for sealing the top of the barrel body 302; a connecting arm 304 is provided at the upper end of the barrel cover 301, and a fixed sleeve 306 sleeved and fixed on the rotating shaft 307 is provided at the other end of the connecting arm 304;

[0094] After the transportation and hoisting module 6 transports the conical original soil mass 8 to directly above the shaping mechanism 3, at this time, the PLC controller controls the fifth motor 308 to work, causing the rotating shaft 307 to rotate. The rotating shaft 307 drives the bucket cover 301 to rotate through the connecting arm 304 and then leaves the top of the bucket body 302;

[0095] Subsequently, after the staff wears professional gloves with a certain thickness, they remove the conical original soil mass 8 from the transportation and hoisting module 6, and quickly place the conical original soil mass 8 at the center of the bottom of the bucket body 302, making the conical original soil mass 8 placed in a state of being narrow at the top and wide at the bottom, so that the conical original soil mass 8 can be placed stably;

[0096] Subsequently, the in-situ soil fill 7 is filled around the outside of the conical original soil mass 8. Finally, the PLC controller controls the fifth motor 308 to work, causing the bucket cover 301 to rotate and seal the top of the bucket body 302;

[0097] The air pipe 305 connected to the top of the airbag 309 passes through the bucket cover 301 and is connected to the air outlet of the air pump. The air pump works under the control of the PLC controller to fill the airbag 309 with air through the air pipe 305, so that the airbag 309 expands to realize the extrusion and compaction of the conical original soil mass 8 and the in-situ soil fill 7;

[0098] The airbag 309 is fixed to the bottom of the bucket cover 301, and a central through groove 311 is provided in the middle of the airbag 309. When the in-situ soil fill 7 is layer-by-layer extruded and compacted by the inflation of the airbag 309, the exposed part of the top of the conical original soil mass 8 can be located in the central through groove 311. Until after the multi-layer in-situ soil fill 7 is extruded and compacted, the in-situ soil fill 7 completely wraps the conical original soil mass 8 and forms a shaped cylindrical soil sample;

[0099] A number of groups of traction wires 310 are also connected between the outer side wall and the inner side wall inside the airbag 309. The traction wires 310 are used to traction the inner side wall inside the airbag 309, so that after the airbag 309 expands, the shape of the central through groove 311 will not be deformed. Furthermore, when the airbag 309 inflates and extrudes and compacts the in-situ soil fill 7, the inflated airbag 309 performs limit extrusion and compaction freezing on the in-situ soil fill 7;

[0100] As Figure 6 shown, it is the sectional view state of the airbag 309 when compacting the bottom in-situ soil fill 7. As Figure 7 shown, it is the sectional view state of the airbag 309 when compacting the upper in-situ soil fill 7.

[0101] As Figure 3 and 8As shown in the figure, a cooling circulation pipe 303 is also provided on the outer side of the barrel body 302. The cooling circulation pipe 303 is communicated with a corresponding cooling pipe 108 on the inner wall of the mobile device box 1. A refrigerator 102 and a coolant tank 103 are provided on the top of the mobile device box 1. The refrigerator 102 is used to cool the coolant in the coolant tank 103 and then introduce it into the cooling pipe 108.

[0102] The PLC controller controls the operation of the refrigerator 102, so that the coolant in the coolant tank 103 is cooled by the refrigerator 102 and then introduced into the cooling pipe 108. At this time, the coolant in the cooling pipe 108 is used to cool the inside of the mobile device box 1, so that when the transportation and hoisting module 6 transports the conical original soil mass 8 and the shaped cylindrical soil sample, it can ensure that the conical original soil mass 8 and the shaped cylindrical soil sample will not be affected by the room temperature.

[0103] The coolant in the corresponding cooling pipe 108 then flows into the cooling circulation pipe 303, so as to realize the cooling of the inside of the barrel cover 301. In this way, when the conical original soil mass 8 and the in-situ soil fill 7 are compacted by ramming, the conical original soil mass 8 and the in-situ soil fill 7 will not be affected by the room temperature, and then the in-situ soil fill 7 is frozen with the conical original soil mass 8 under the ramming of the airbag 309.

[0104] As Figure 9 and 14 shown, the transportation and hoisting module 6 includes a sliding seat 603 slidably connected to the inverted U-shaped cross frame 107, a winding drum 605 arranged at the top of the sliding seat 603 and driven to rotate by a first motor 604, a lifting plate 601 hoisted by a steel rope 606 on the winding drum 605, an installation frame 608 connected to the upper end of the lifting plate 601 through a first electric cylinder 607, and two groups of second motors 609 symmetrically fixed on the installation frame 608. The bottom output end of the second motor 609 is connected with a drill bit 602, and the bottom of the drill bit 602 penetrates through the lifting plate 601.

[0105] A horizontal movement motor for driving a rotating wheel to rotate can also be arranged on the sliding seat 603. The rotating wheel is close to the side wall of the inverted U-shaped cross frame 107 (not shown in the figure). The PLC controller controls the operation of the horizontal movement motor, so that the rotating wheel rotates on the side wall of the inverted U-shaped cross frame 107, so as to realize the left and right horizontal movement of the transportation and hoisting module 6 on the inverted U-shaped cross frame 107.

[0106] It is also possible to manually push the sliding seat 603 left and right to realize the left and right horizontal movement of the transportation and hoisting module 6 on the inverted U-shaped cross frame 107.

[0107] After the arc-shaped seepage cutter 409 rotates and cuts to obtain the conical original soil mass 8, the PLC controller controls the third motor 402 to stop working. Subsequently, the transportation and hoisting module 6 is integrally moved directly above the primary cutting module 4. The PLC controller controls the first motor 604 to work, causing the cable reel 605 to rotate to release the steel cable 606. At this time, under the action of gravity, the lifting plate 601 moves down to the upper surface of the conical original soil mass 8;

[0108] Then the PLC controller controls the second motor 609 to drive the drill bit 602 to rotate. The PLC controller controls the piston rod of the first electric cylinder 607 to retract, causing the mounting bracket 608 and the second motor 609 to lower in height. The drill bit 602 penetrates through the lifting plate 601 and drills into the conical original soil mass 8;

[0109] Finally, the PLC controller controls the second motor 609 to stop working, and the drill bit 602 stops rotating. The PLC controller controls the first motor 604 to work, causing the cable reel 605 to rotate to wind up the steel cable 606. At this time, the lifting plate 601 and the conical original soil mass 8 are lifted upward.

[0110] The transportation and hoisting module 6 is slidably connected to the inverted U-shaped cross frame 107 on the bottom plate 106. The transportation and hoisting module 6 is used to transport the conical original soil mass 8 directly above the shaping mechanism 3, and to transport the shaped cylindrical soil sample directly above the secondary cutting module 5;

[0111] After the transportation and hoisting module 6 lifts and removes the conical original soil mass 8 from the primary cutting module 4, the transportation and hoisting module 6 is moved to the left until the conical original soil mass 8 is transported directly above the shaping mechanism 3. When the staff removes the conical original soil mass 8, the PLC controller needs to control the piston rod of the first electric cylinder 607 to extend, causing the mounting bracket 608 and the second motor 609 to rise in height, and the drill bit 602 to disengage from the conical original soil mass 8 so that the staff can remove the conical original soil mass 8.

[0112] After the shaping mechanism 3 compacts and rams the conical original soil mass 8 and the in-situ soil fill 7 in the barrel 302 to obtain the shaped cylindrical soil sample, the lifting plate 601 is controlled to move down to the upper surface of the shaped cylindrical soil sample. Subsequently, while controlling the drill bit 602 to rotate, the height of the drill bit 602 continues to decrease until the drill bit 602 penetrates through the lifting plate 601 and drills into the shaped cylindrical soil sample;

[0113] Finally, the lifting plate 601 is controlled to rise, causing the shaped cylindrical soil sample to leave the barrel 302. Then the transportation and hoisting module 6 transports the shaped cylindrical soil sample directly above the secondary cutting module 5.

[0114] The secondary cutting module 5 is used for vibration cutting of the shaped cylindrical soil sample with variable dimensions to obtain the frozen soil sampling test specimen block 9.

[0115] As Figures 15 - 24 shown, the secondary cutting module 5 includes a temporary storage box 501 connected to the bottom of the annular hole seat 1061 on the bottom plate 106, a support seat 529 connected to the bottom plate 106 by a support component, equally spaced and openable enclosure blades 508 on the side of the support seat 529, vertical track seats 502 arranged on the front and rear sides of the annular hole seat 1061 on the bottom plate 106, a lifting frame component slidably connected to the vertical track seats 502, a second electric cylinder 517 connected to the lifting frame component by a vibration component 511, and a cutting tool 506 connected to the output end of the second electric cylinder 517 by an adjusting component.

[0116] The PLC controller controls the piston rod of the output end of the second electric cylinder 517 to extend or retract, so that the two cutting tools 506 approach or move away from each other, and the distance between the two cutting tools 506 can be adjusted.

[0117] As Figures 15 - 17 and shown in FIG. 23, the support component includes two groups of third electric cylinders 503 fixed on the bottom plate 106, a lifting support plate 505 connected to the top of the output ends of the two groups of third electric cylinders 503, and a lifting rod 504 fixed in the middle of the lifting support plate 505. The bottom of the lifting rod 504 passes through the bottom plate 106 and is fixed to the support seat 529;

[0118] The PLC controller controls the piston rod of the third electric cylinder 503 to extend or retract, so that the lifting support plate 505 moves up and down the support seat 529 through the lifting rod 504;

[0119] After the frozen soil sampling test specimen block 9 is obtained, the piston rod of the third electric cylinder 503 retracts, so that the lifting support plate 505 moves down through the lifting rod 504, and the frozen soil sampling test specimen block 9 on the support seat 529 is moved down into the temporary storage box 501, so that the temporary storage box 501 stores the frozen soil sampling test specimen block 9, and a protective door 509 is provided on the side of the temporary storage box 501. After the protective door 509 is opened, the frozen soil sampling test specimen block 9 can be taken out.

[0120] As Figure 24 shown, U-shaped seats 531 are equally spaced on the side of the support seat 529, a connecting head 532 movably connected to the inside of the end of the U-shaped seat 531 by a connecting pin rod, and a sixth motor 530 fixed on the U-shaped seat 531 for driving the connecting pin rod. The bottom of the enclosure blade 508 is fixed to the connecting head 532;

[0121] After the cutting tool 506 cuts the shaped cylindrical soil sample to obtain the frozen soil sampling test specimen block 9, the cutting tool 506 moves away and resets, so that the cutting tool 506 leaves the frozen soil sampling test specimen block 9. Subsequently, the PLC controller controls the operation of the sixth motor 530, so that the connecting pin rod drives the connecting head 532 and the enclosing blades 508 to turn upward until a plurality of groups of enclosing blades 508 are closed to fix the frozen soil sampling test specimen block 9 (as Figure 23 shown).

[0122] As Figure 18 and 20 shown, the lifting frame assembly includes a lifting seat 513 sleeved on the vertical track seat 502 and a seventh motor 507 installed on the lifting seat 513 for driving the rollers 510. The rollers 510 are closely attached to the side wall of the vertical track seat 502;

[0123] The PLC controller controls the operation of the seventh motor 507, so that the rollers 510 roll along the side wall of the vertical track seat 502, thereby realizing the up and down movement of the lifting seat 513 along the vertical track seat 502.

[0124] As Figure 18 shown, the vibration assembly 511 includes a rectangular mounting frame seat 515 connected by a U-shaped member 516 inside the lifting seat 513, a vibration block 520 arranged inside the rectangular mounting frame seat 515, and a vibration motor 514 installed at one end of the vibration block 520. The second electric cylinder 517 is installed at the other end of the vibration block 520;

[0125] The protruding block 521 on the side of the vibration block 520 penetrates through the vertical through groove on the side of the rectangular mounting frame seat 515, and the upper and lower ends of the protruding block 521 are connected and fixed to the upper and lower walls of the vertical through groove by buffer springs 522. Such a setting enables the vibration block 520 to achieve the effect of rapid up and down reciprocating movement when vibrating inside the rectangular mounting frame seat 515;

[0126] The PLC controller controls the operation of the vibration motor 514, so that the vibration block 520 drives the cutting tool 506 to move up and down rapidly and reciprocally, so that the cutting tool 506 cuts the shaped cylindrical soil sample up and down.

[0127] As Figure 19 shown, the adjusting member includes a motor seat 519 connected to the output end of the second electric cylinder 517, an eighth motor 518 installed on the top of the motor seat 519, and an upper driving wheel 525 and a lower driven wheel 524 which are movably connected to the outer side end of the motor seat 519 and are distributed up and down. The eighth motor 518 is used to drive the rotation of the upper driving wheel 525;

[0128] A guide rail 523 is provided in the middle of the outer side of the cutting tool 506, and track grooves 526 for accommodating the upper driving wheel 525 and the lower driven wheel 524 are respectively provided at the upper and lower ends of the guide rail 523.

[0129] The PLC controller controls the operation of the eighth motor 518, and the eighth motor 518 drives the upper driving wheel 525 to rotate within the upper track groove 526, thereby enabling the upper driving wheel 525 to adjust the position of the cutting tool 506 (as Figure 21 and 22 shown), and further enabling the cutting tool 506 to cut the shaped cylindrical soil sample into frozen soil sampling specimen blocks 9 of different sizes.

[0130] As Figure 20 shown, an electric heating wire is integrated inside the cutting edge of the cutting tool 506. After the PLC controller controls the electric heating wire to be energized, the temperature of the cutting edge of the cutting tool 506 rises. When the cutting tool 506 cuts the shaped cylindrical soil sample, the cutting point between the cutting edge and the shaped cylindrical soil sample melts;

[0131] Cooling air holes are provided on the inner wall of the cutting tool 506, and a cooling gas pipe 512 communicating with the cooling air holes is provided on the outer wall of the cutting tool 506. The other end of the cooling gas pipe 512 is communicated with a high-pressure cooling gas tank 527 inside the mobile equipment box 1, and a solenoid valve 528 is also provided on the cooling gas pipe 512.

[0132] When the cutting tool 506 cuts the shaped cylindrical soil sample, the PLC controller controls the solenoid valve 528 to open, so that the low-temperature gas in the high-pressure cooling gas tank 527 is introduced into the inside of the cutting tool 506 through the cooling gas pipe 512, and finally sprayed out to the surface of the shaped cylindrical soil sample through the cooling air holes, so that the cutting surface between the cutting tool 506 and the shaped cylindrical soil sample is cooled.

[0133] Specifically, during use, when the arc-shaped seepage knife 409 extends downward along the arc-shaped seepage knife seat 408 to the state as Figure 9 shown, the bottom of the arc-shaped seepage knife 409 is inserted into the original soil body. Subsequently, through the rotation of the inner ring seat 404 of the rotating assembly, the arc-shaped seepage knife 409 at the bottom of the inner ring seat 404 rotates and cuts the original soil body to obtain a conical original soil body block 8. Subsequently, the inner ring seat 404 stops rotating;

[0134] The transportation and hoisting module 6 moves directly above the primary cutting module 4, and then the winding drum 605 rotates to release the steel rope 606. The lifting plate 601 moves downward to the upper end of the conical original soil body block 8. While the drill bit 602 rotates, its height decreases. The drill bit 602 penetrates through the lifting plate 601 and drills into the conical original soil body block 8. Then the lifting plate 601 moves upward and resets, lifting the conical original soil body block 8 into the mobile equipment box 1, and the transportation and hoisting module 6 moves directly above the shaping mechanism 3;

[0135] Open the bucket cover 301, remove the conical original soil mass 8 from the transportation and hoisting module 6, and quickly place the conical original soil mass 8 at the center of the bottom of the barrel 302, so that the conical original soil mass 8 is placed in a state of being narrow at the top and wide at the bottom;

[0136] Subsequently, fill the in-situ soil fill 7 around the outside of the conical original soil mass 8 (the in-situ soil fill 7 can be the soil around the original soil, with a similar water content, and it can be frozen around the conical original soil mass 8 after tamping);

[0137] After the bucket cover 301 rotates, seal the top of the barrel 302. After the airbag 309 expands, it realizes the extrusion and compaction of the conical original soil mass 8 and the in-situ soil fill 7, so that the in-situ soil fill 7 completely wraps the conical original soil mass 8 and forms a shaped columnar soil sample;

[0138] Then open the bucket cover 301, use the transportation and hoisting module 6 to lift the shaped columnar soil sample in the barrel 302 into the mobile equipment box 1. The transportation and hoisting module 6 moves the shaped columnar soil sample directly above the secondary cutting module 5, and the lifting plate 601 of the transportation and hoisting module 6 descends in height, so that the shaped columnar soil sample is stuck between the lifting plate 601 and the support 529 (at this time, the enclosure blade 508 is in the unfolded state as shown in Figure 17 ). Subsequently, the drill bit 602 rises to the reset height, so that the drill bit 602 disengages from the shaped columnar soil sample;

[0139] After that, the PLC controller controls the seventh motor 507 to work, so that the roller 510 rolls along the side wall of the vertical track seat 502, thereby realizing the up and down movement of the lifting seat 513 along the vertical track seat 502, and further making the cutting tool 506 move to a suitable height. And the PLC controller controls the piston rod of the output end of the second electric cylinder 517 to extend, so that the two groups of cutting tools 506 approach each other until the cutting tool 506 contacts the side of the shaped columnar soil sample;

[0140] Then, the PLC controller controls the vibration motor 514 to work, so that the vibration block 520 drives the cutting tool 506 to move up and down quickly and reciprocally, so that the cutting tool 506 performs "flexible" cutting on the shaped columnar soil sample up and down;

[0141] At the same time, the PLC controller controls the eighth motor 518 to work. The eighth motor 518 drives the upper driving wheel 525 to rotate in the upper track groove 526, so that the upper driving wheel 525 drives the position of the cutting tool 506 to be adjusted (as shown in Figure 21 and 22 ), and further realizes that the cutting tool 506 cuts the shaped columnar soil sample into frozen soil sampling test specimen blocks 9 of different sizes;

[0142] After the frozen soil sampling specimen block 9 is obtained, the cutting tool 506 moves back to its initial state. Then, the lifting plate 601 of the transportation and hoisting module 6 moves up and resets to the state as shown in Figure 17 the figure;

[0143] Subsequently, the PLC controller controls the operation of the sixth motor 530, causing the connecting pin rod to drive the connecting head 532 and the retaining blades 508 to flip upwards until the retaining blades 508 of several groups are closed to fix the frozen soil sampling specimen block 9 (as shown in Figure 23 the figure);

[0144] Finally, the PLC controller controls the piston rod of the third electric cylinder 503 to retract, causing the lifting support plate 505 to lower the height of the retaining seat 529 and the frozen soil sampling specimen block 9 fixed at the upper end of the retaining seat 529 through the lifting rod 504 until the frozen soil sampling specimen block 9 on the retaining seat 529 is moved down into the temporary storage box 501, enabling the temporary storage box 501 to store the frozen soil sampling specimen block 9. A protective door 509 is provided on the side of the temporary storage box 501. After the protective door 509 is opened, the frozen soil sampling specimen block 9 can be taken out.

[0145] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
