Description

Technical Field

[0001] The invention relates to the technical field of frozen soil excavation and shaping, in particular to a salt-thermal power cone-arc knife temperature-controlled disturbance-free cone-shaped frozen soil excavation and shaping device. Background Art

[0002] In the winter, the irrigation areas in the cold and arid regions of the north have large water content in the channels, complex freezing conditions, and strong freezing, which leads to large frost heave deformation and different deformation patterns, resulting in frost heave damage to the irrigation channels, mainly manifested in the reduction of channel impermeability and regional lining structure damage caused by frost heave deformation of the channel base soil. Therefore, in order to better design and protect the channels against frost heave, ensure the long-term stable service of the channels, improve the channel's anti-permeability, and increase the service life of the channel lining, it is necessary to understand in detail the deformation development laws of freezing and frost heave of the channel base soil under actual working conditions. In practice, the soil-ice body in the channel is layered and disordered, and is more fragile under strong freezing conditions. This requires accurate in-situ sampling of frozen soil columns in an undisturbed state as much as possible to ensure the accuracy of the test data.

[0003] At present, when conducting in-situ sampling of frozen soil in the field, there are often many inconveniences and insurmountable limitations. First, due to the complexity and variability of the winter environment of field irrigation channels, soil sampling operations are often affected by multiple factors such as topography, climate, soil properties, and human factors. The most important factor is that the sampling equipment has a great impact. During the sampling process of frozen soil, disturbances are inevitable, destroying the internal structural characteristics of the frozen soil. At present, the usual practice of sampling frozen soil is to manually operate the ring cutter and the barrel drill for sampling.

[0004] Although the traditional ring knife soil extraction method can meet the soil extraction needs when the water content is relatively low and the soil is not frozen, its limitations are also obvious. On the one hand, the ring knife is not suitable for frozen soil. It is difficult to extract soil with the ring knife in the frozen state with high water content. The soil extraction depth is small, and it is difficult to extract after the ring knife is pressed or hammered into the frozen soil. After the ring knife is pressed into the frozen soil, the metal quickly freezes to low temperature, and the ring knife and the soil are frozen together, making it difficult to extract. On the other hand, the frozen soil is greatly disturbed during the process of the ring knife being forced into or hammered into the soil. The ring knife soil extraction has a great damage to the soil structure in the frozen state, especially when the sampling point is deep, which is easy to destroy the pore structure of the soil, thereby affecting the physical and mechanical properties of the soil.

[0005] In addition, it is common to use a cylindrical drill to collect soil for frozen soil sampling. Drilling soil sampling cuts the soil by rotating the drill bit, which is efficient and flexible, and can significantly improve the efficiency of soil collection. However, there are certain limitations to drilling soil sampling. Since the cylindrical drill bit rotates at high speed during the process of cutting frozen soil, it will generate large vibrations and impact forces, causing certain disturbances to the soil, including but not limited to the irregular shape of the soil column. In addition, in the winter when the ambient temperature is low, the drill will inevitably stop during the soil collection process, which will cause the drill bit and the soil to freeze together and be difficult to separate, resulting in sampling failure. In addition, drilling soil sampling requires a high moisture content of the soil, and soil that is too wet or too dry may result in poor soil collection results. When using a drill to collect soil, it is necessary to select and adjust according to the specific conditions of the soil. In addition, during the process of drilling soil sampling, a large amount of heat is generated due to the friction between the high-speed rotation of the drill bit and the soil or ice body, which causes the ice body radiating from the surface of the soil to the center to melt and freeze, and water migration occurs, which cannot truly restore the original appearance of the soil. Due to the natural limitations of the drill bit, the bottom of the frozen soil sample column is still attached to the matrix. In actual operation, a pry bar is usually used to pry the side wall to break the bottom. Due to the high water content of the channel soil, the obvious stratification of water, ice and soil, and the uneven distribution of the fragile surface of the soil column, this prying operation often leads to a large randomness in the actual fracture position. After being subjected to external force, microcracks in the soil body initiate, which has a great impact on the subsequent test process. To this end, we introduced a salt thermal power cone arc knife temperature control non-disturbance cone frozen soil shaping device. Summary of the invention

In addition, the air bag is used with the internal traction wire for limited compaction to achieve in-situ soil compaction and freezing without disturbing the original conical original soil block, avoiding the oblique stress caused by the inclined contact between the cutting blade and the cutting surface during the cutting process, which affects the distribution of internal cracks.

[0019] Compared with ordinary ring cutters, the present invention uses a variable diameter high-frequency vibrating cutting knife to gradually move up and down to peel off the frozen soil, and combines a shiftable cutting knife to realize a variable size ring cutting process. The cutting knife and the cylindrical fitting surface form a cavity, which can achieve rapid cooling in the cavity during cutting; the cutting knife blade adopts an electric heating strategy when cutting up and down to achieve a rapid state transition from melting at the cutting point to cooling on the cutting surface, avoiding the disturbance of the soil core sample 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 preserving the original natural frozen structure of the soil.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example: See also Figure 1-24 , the present invention provides a technical solution: The present invention is applicable to the integrated equipment for undisturbed preparation, cutting and shaping of frozen soil samples of high-water-content canal foundation soil in northern irrigation channels. Through step-by-step cutting and reshaping, the salt thermal power conical knife is used to realize resistance heating salt infiltration cutting to achieve soil separation; the original soil is then used for secondary limited freezing, and a variable cone barrel-shaped airbag is used for compaction to change the soil sample morphology to avoid internal stress concentration of the soil sample during the cutting process; high-frequency quick freezing and quick thawing ring cutting is used to achieve frozen soil sampling. The present invention aims to restore the natural structure of frozen soil, avoid disturbance of the soil body during the soil sample preparation process, reduce labor costs and the influence of human factors, and provide real scene restoration for subsequent scientific research.

The global control module 2 includes a display fixed to the side of the mobile equipment box 1 and a PLC controller built into the display.

[0025] like Figure 1 and 2 As shown, the primary cutting module 4 is arranged in the middle of the base plate 106, the shaping mechanism 3 and the secondary cutting module 5 are respectively arranged on the left and right sides of the base plate 106, and the primary cutting module 4 is located between the shaping mechanism 3 and the secondary cutting module 5.

[0026] A fourth electric cylinder 104 is provided at the bottom of the base plate 106, and a moving wheel 105 is connected to the bottom output end of the fourth electric cylinder 104; the PLC controller controls the piston rod at the output end of the fourth electric cylinder 104 to extend, thereby raising the height of the equipment moving box 1, and when the position is moved by the moving wheel 105, the bottom of the primary cutting module 4, the shaping mechanism 3 and the secondary cutting module 5 are prevented from contacting the ground.

[0027] The primary cutting module 4 includes a rotating assembly connected to the bottom plate 106 at the bottom of the mobile equipment box 1, a seepage cutter assembly connected to the bottom of the rotating assembly, and a saline pipeline system for discharging saline through the arc-shaped seepage cutter 409 of the seepage cutter assembly; like Figure 2 , 9 As shown in FIG. 10 , the rotating assembly 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 to the upper end of the outer ring seat 401 , and an inner ring seat 404 slidably buckled on the inner side of the outer ring seat 401 ; The first driving gear 412 at the output end of the third motor 402 is meshed with the gear ring seat 413 at the upper end of the inner ring seat 404. The PLC controller controls the third motor 402 to work, so that the first driving gear 412 drives the inner ring seat 404 to rotate inside the outer ring seat 401 through the gear ring seat 413, so that when the arc-shaped seepage knife 409 is extended to the position as shown in FIG. Fig. 9 In the state shown, the rotation of the inner ring seat 404 can drive the seepage cutting knife assembly at the bottom thereof to rotate and cut the original soil.

[0028] like Fig.11 , 12 As shown in FIG. 13 , the arc-shaped seepage knife 409 of the seepage cutting knife assembly is retractable, and the seepage cutting knife assembly includes an arc-shaped seepage knife seat 408 fixed at equal intervals at the bottom of the inner ring seat 404 by a connecting frame 406, two upper and lower groups of I-shaped sliders 416 slidingly connected in the slot 4081 in the middle of the arc-shaped seepage knife seat 408, a connecting plate 410 connected between the upper and lower groups of I-shaped sliders 416, and a fourth motor 415 fixed on the outer side of the I-shaped slider 416; The upper part of the arc-shaped seepage knife 409 is fixed to the inner wall of the upper and lower sets of I-shaped sliding blocks 416; The rotating shaft 418 inside the I-shaped slider 416 is fixed with a second driving gear 417, and the output end of the fourth motor 415 is provided with a motor gear meshing with the inner side of the second driving gear 417; The side of the I-shaped slide block 416 is provided with a U-shaped slide groove 4161 which is slidably connected to the inner wall of the slot 4081; 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 slide groove 4161 and engages 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 sliding blocks 416 and the connecting plate 410 are moved up and down along the slot 4081 as a whole, thereby driving the arc seepage knife 409 to move up and down along the arc seepage knife seat 408, so as to realize the retractability of the arc seepage knife 409.

[0029] The arc-shaped seepage knife 409 extends downward along the arc-shaped seepage knife seat 408 to a position as Fig. 9 In the state shown, the bottom of the arc-shaped seepage knife 409 is inserted into the original soil, and then the inner ring seat 404 of the rotating assembly rotates, driving the arc-shaped seepage knife 409 at the bottom of the inner ring seat 404 to rotate and cut the original soil to obtain a conical original soil block 8.

[0030] like Figure 1 , 9 As shown in Figure 10, the saline pipeline system includes an upper liquid guide pipe 411 connected between the saline tank 101 on the top of the mobile equipment box 1 and the outer ring seat 401, and a lower liquid guide hose 407 connected between the inner ring seat 404 and the arc-shaped seepage knife 409; The upper liquid guiding tube 411 and the lower liquid guiding hose 407 are connected through the annular groove 414 between the outer ring seat 401 and the inner ring seat 404; like Fig.13 As shown, the inner surface of the arc-shaped seepage knife 409 is provided with a plurality of groups of liquid outlet holes 4091 distributed vertically, and the liquid outlet holes 4091 are connected to the bottom of the lower liquid guiding hose 407 through the channel inside the arc-shaped seepage knife 409.

[0031] The salt solution in the salt solution box 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 liquid outlet 4091 through the lower liquid guide hose 407 and the channel inside the arc-shaped seepage knife 409. In this way, when the arc-shaped seepage knife 409 rotates and cuts the original soil, the salt solution contacts the surface of the conical original soil block 8, which can prevent the cut conical original soil block 8 from freezing and sticking to the original soil.

[0032] The blade of the arc-shaped seepage knife 409 is provided with an electric heating wire, and the rotating assembly drives the seepage cutting knife assembly to rotate, so that the original soil is cut by the arc-shaped seepage knife 409 to obtain a conical original soil block 8; During the cutting process, the blade of the arc-shaped seepage knife 409 is heated by energizing the electric heating wire, which can also prevent the cut conical original soil block 8 from freezing and adhering to the original soil.

The air bag 309 expands after intake of air, and is used to squeeze, compact and freeze the conical original soil block 8 and the in-situ soil filling 7 placed inside the barrel body 302, and obtain a shaped columnar soil sample; like Figure 3 and 4As shown, the barrel cover assembly includes a rotating shaft 307 movably connected between the front and rear sets of 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 fixing sleeve 306 sleeved and fixed on the rotating shaft 307 is provided at the other end of the connecting arm 304; After the transport hoisting module 6 transports the conical original soil block 8 to the top of the shaping mechanism 3, the PLC controller controls the fifth motor 308 to work, so that the rotating shaft 307 rotates, and the rotating shaft 307 drives the barrel cover 301 to rotate through the connecting arm 304 and then leaves the top of the barrel body 302; Then, after putting on professional gloves with a certain thickness, the staff takes the conical original soil block 8 off the transport and hoisting module 6, and quickly places the conical original soil block 8 at the bottom center of the barrel 302, so that the conical original soil block 8 is placed in a narrow upper and wide lower state, so that the conical original soil block 8 can be placed stably; Then, the in-situ soil filling 7 is filled around the outer side of the conical original soil block 8, and finally the PLC controller controls the fifth motor 308 to work, so that the barrel cover 301 rotates to seal the top of the barrel body 302; The air pipe 305 connected to the top of the air bag 309 passes through the barrel cover 301 and is connected to the air outlet of the air pump. The air pump works under the control of the PLC controller and is used to fill air into the air bag 309 through the air pipe 305, so that the air bag 309 can be expanded to squeeze and compact the conical original soil block 8 and the in-situ soil filling 7; The airbag 309 is fixed at the bottom of the barrel cover 301, and a central through groove 311 is provided in the middle of the airbag 309. When the in-situ soil filling 7 is squeezed and compacted layer by layer by the air intake and expansion of the airbag 309, the exposed portion of the top of the conical original soil block 8 can be located in the central through groove 311, until the in-situ soil filling 7 is squeezed and compacted for multiple layers, so that the in-situ soil filling 7 is completely wrapped with the conical original soil block 8 and a shaped columnar soil sample is formed; A plurality of traction wires 310 are connected between the outer wall and the inner wall of the airbag 309. The traction wires 310 are used to traction the inner wall of the airbag 309, so that after the airbag 309 is expanded, the shape of the central through groove 311 will not be deformed. When the airbag 309 is expanded and squeezes and tamps the in-situ soil filling 7, the expanded airbag 309 can limit the position, squeeze, tamp and freeze the in-situ soil filling 7. like Figure 6 As shown in FIG. 1 , it is a cross-sectional view of the airbag 309 when the in-situ soil fill 7 of the bottom layer is squeezed and compacted. Figure 7 As shown, it is a cross-sectional view of the airbag 309 when the upper in-situ soil fill 7 is squeezed and compacted.

[0034] like Figure 3 and 8 As shown, a cooling circulation pipe 303 is also provided on the outside of the barrel body 302, and the cooling circulation pipe 303 is connected to the corresponding cooling pipe 108 on the inner wall of the mobile equipment box 1, and a refrigerator 102 and a coolant tank 103 are provided on the top of the mobile equipment 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.

[0035] The PLC controller controls the refrigerator 102 to work, so that the coolant in the coolant tank 103 of the refrigerator 102 is cooled 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 equipment box 1, so that when the transport hoisting module 6 transports the conical original soil block 8 and the shaped column soil sample, it can ensure that the conical original soil block 8 and the shaped column soil sample will not be affected by the room temperature; The coolant in the corresponding cooling pipe 108 then flows into the cooling circulation pipe 303, thereby achieving cooling of the inside of the barrel cover 301. In this way, when the conical original soil block 8 and the in-situ soil fill 7 are squeezed and compacted, the conical original soil block 8 and the in-situ soil fill 7 will not be affected by the room temperature, and the in-situ soil fill 7 can be frozen together with the conical original soil block 8 under the compaction of the air bag 309.

[0036] like Fig. 9 and 14 As shown, the transport hoisting module 6 includes a slide 603 slidably connected to the inverted U-shaped cross frame 107, a winding drum 605 arranged on the top of the slide 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, a mounting frame 608 connected to the upper end of the lifting plate 601 through a first electric cylinder 607, and two sets of second motors 609 symmetrically fixed on the mounting frame 608, the bottom output end of the second motor 609 is connected to a drill bit 602, and the bottom of the drill bit 602 passes through the lifting plate 601; A horizontal moving motor for driving the rotating wheel to rotate can also be arranged on the slide 603, and the rotating wheel is close to the side wall of the inverted U-shaped horizontal frame 107 (not shown in the figure). The PLC controller controls the horizontal moving motor to work, so that the rotating wheel rotates on the side wall of the inverted U-shaped horizontal frame 107, thereby realizing the left and right horizontal movement of the transport hoisting module 6 on the inverted U-shaped horizontal frame 107; The slide 603 can also be manually pushed to move left and right to achieve the horizontal movement of the transport hoisting module 6 on the inverted U-shaped cross frame 107; After the arc-shaped seepage knife 409 rotates and cuts to obtain the conical original soil block 8, the PLC controller controls the third motor 402 to stop working, and then the transport hoisting module 6 moves as a whole to just above the primary cutting module 4. The PLC controller controls the first motor 604 to work, so that the winding drum 605 rotates to release the steel rope 606. At this time, under the action of gravity, the lifting plate 601 moves down to the upper end surface of the conical original soil block 8; Then the PLC controller controls the second motor 609 to drive the drill bit 602 to rotate, and the PLC controller controls the piston rod of the first electric cylinder 607 to retract, so that the height of the mounting frame 608 and the second motor 609 is reduced, and the drill bit 602 penetrates the lifting plate 601 and then drills into the conical original soil block 8; Finally, the PLC controller controls the second motor 609 to stop working, the drill bit 602 no longer rotates, and the PLC controller controls the first motor 604 to work, so that the winding drum 605 rotates to achieve the winding of the steel rope 606. At this time, the lifting plate 601 and the conical original soil block 8 are moved upward.

[0037] The transport hoisting module 6 is slidably connected to the inverted U-shaped cross frame 107 on the bottom plate 106. The transport hoisting module 6 is used to transport the conical original soil block 8 to the top of the shaping mechanism 3, and to transport the shaped column soil sample to the top of the secondary cutting module 5. After the transport hoisting module 6 moves the conical original soil block 8 up and out of the primary cutting module 4, the transport hoisting module 6 moves to the left until the conical original soil block 8 is transported to the top of the shaping mechanism 3. When the staff removes the conical original soil block 8, the PLC controller needs to control the piston rod of the first electric cylinder 607 to extend, so that the mounting frame 608 and the second motor 609 rise in height, and the drill bit 602 is separated from the conical original soil block 8, so that the staff can remove the conical original soil block 8.

[0038] After the shaping mechanism 3 squeezes and compacts the conical original soil block 8 and the in-situ soil filling 7 in the barrel 302 and obtains a shaped columnar soil sample, the lifting plate 601 is controlled to move down to the upper end surface of the shaped columnar soil sample, and then the drill bit 602 is controlled to rotate while the height of the drill bit 602 continues to decrease until the drill bit 602 penetrates the lifting plate 601 and drills into the shaped columnar soil sample; Finally, the lifting plate 601 is controlled to rise, so that the shaped column soil sample leaves the barrel 302 , and then the transport hoisting module 6 transports the shaped column soil sample to just above the secondary cutting module 5 .

[0039] The secondary cutting module 5 is used to perform vibration cutting of the shaped cylindrical soil sample with variable size to obtain the frozen soil sample block 9.

[0040] like Figure 15-24As shown, the secondary cutting module 5 includes a temporary storage box 501 connected to the bottom of the annular hole seat 1061 on the base plate 106, a bracket 529 connected to the base plate 106 by a supporting assembly, a retaining blade 508 that can be opened and closed at equal intervals on the side of the bracket 529, a vertical track seat 502 arranged on the base plate 106 and located on the front and rear sides of the annular hole seat 1061, a lifting frame assembly sliding on the vertical track seat 502, a second electric cylinder 517 connected to the lifting frame assembly by a vibration assembly 511, and a cutting knife 506 connected to the output end of the second electric cylinder 517 by an adjusting member.

[0041] The PLC controller controls the piston rod at the output end of the second electric cylinder 517 to extend or retract, thereby moving the two groups of cutting blades 506 closer or farther away, so that the distance between the two groups of cutting blades 506 can be adjusted.

[0042] like Figure 15-17 As shown in FIG. 23 , the supporting assembly includes two sets of third electric cylinders 503 fixed on the bottom plate 106, a lifting support plate 505 connected to the top of the output end of the two sets of third electric cylinders 503, and a lifting rod 504 fixed in the middle of the lifting support plate 505, and the bottom of the lifting rod 504 passes through the bottom plate 106 and is fixed to the bracket 529; The PLC controller controls the extension or retraction of the piston rod of the third electric cylinder 503, so that the lifting support plate 505 realizes the up and down movement of the support seat 529 through the lifting rod 504; After the frozen soil sample block 9 is obtained, the piston rod of the third electric cylinder 503 retracts, so that the lifting support plate 505 moves the frozen soil sample block 9 on the support seat 529 downward into the temporary storage box 501 through the downward movement of the lifting rod 504, so that the temporary storage box 501 can store the frozen soil sample block 9, and a protective door 509 is provided on the side of the temporary storage box 501. After opening the protective door 509, the frozen soil sample block 9 can be taken out.

Subsequently, the PLC controller controls the sixth motor 530 to operate, so that the connecting pin drives the connecting head 532 and the enclosure blade 508 to flip upward until several groups of enclosure blades 508 are closed to fix the frozen soil sample block 9 (such as Fig.23 as shown).

[0044] like Fig.18 and20 As 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 a roller 510, and the roller 510 is closely attached to the side wall of the vertical track seat 502; 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 enabling the lifting seat 513 to move up and down along the vertical track seat 502 .

[0045] like Fig.18 As shown, the vibration assembly 511 includes a rectangular mounting frame seat 515 connected to the inner side of a lifting seat 513 by a U-shaped piece 516, a vibration block 520 disposed inside the rectangular mounting frame seat 515, and a vibration motor 514 mounted at one end of the vibration block 520, and a second electric cylinder 517 is mounted at the other end of the vibration block 520; The protruding block 521 on the side of the vibration block 520 extends through the vertical through slot on the side of the rectangular mounting frame 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 slot by using a buffer spring 522. Such a configuration enables the vibration block 520 to achieve the effect of rapid up and down reciprocating movement when vibrating in the rectangular mounting frame 515. The PLC controller controls the vibration motor 514 to work, so that the vibration block 520 drives the cutting knife 506 to move up and down quickly, so that the cutting knife 506 cuts the shaped column soil sample up and down.

[0046] like Fig.19 As shown, the adjusting member includes a motor base 519 connected to the output end of the second electric cylinder 517, an eighth motor 518 installed on the top of the motor base 519, and an upper driving wheel 525 and a lower driven wheel 524 that are movably connected to the outer end of the motor base 519 and are distributed up and down.

[0048] like Fig. 20As shown, the blade of the cutting knife 506 is internally integrated with an electric heating wire. After the PLC controller controls the electric heating wire to be energized, the temperature of the blade of the cutting knife 506 rises. When the cutting knife 506 cuts the shaped cylindrical soil sample, the cutting point of the blade and the shaped cylindrical soil sample melts; The inner wall of the cutting blade 506 is provided with cooling air holes, and the outer wall of the cutting blade 506 is provided with a cooling gas pipe 512 connected to the cooling air holes. The other end of the cooling gas pipe 512 is connected to the high-pressure cooling gas tank 527 in the mobile equipment box 1, and the cooling gas pipe 512 is also provided with a solenoid valve 528.

[0049] When the cutting blade 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 interior of the cutting blade 506 through the cooling gas pipe 512, and finally sprayed to the surface of the shaped cylindrical soil sample through the cooling air holes, so that the cutting surface of the cutting blade 506 and the shaped cylindrical soil sample is cooled.

The drill bit 602 rotates and drops in height. The drill bit 602 penetrates the lifting plate 601 and then drills into the conical original soil block 8. Then the lifting plate 601 moves up and resets, and the conical original soil block 8 is lifted into the mobile equipment box 1. The transport hoisting module 6 moves to the top of the shaping mechanism 3; Open the barrel cover 301, remove the conical original soil block 8 from the transport and hoisting module 6, and quickly place the conical original soil block 8 at the bottom center of the barrel body 302, so that the conical original soil block 8 is placed in a state of being narrow at the top and wide at the bottom; Then, fill the outer side of the conical original soil block 8 with the in-situ soil filling 7 (the in-situ soil filling 7 can be the soil around the original soil, with a similar moisture content, and can be frozen around the outer side of the conical original soil block 8 after compaction); The barrel cover 301 rotates to seal the top of the barrel body 302, and the airbag 309 expands to squeeze and compact the conical original soil block 8 and the in-situ soil filling 7, so that the in-situ soil filling 7 is completely wrapped with the conical original soil block 8 to form a shaped columnar soil sample; Then, the barrel cover 301 is opened, and the shaped column soil sample in the barrel body 302 is lifted into the mobile equipment box 1 by using the transport hoisting module 6. The transport hoisting module 6 moves the shaped column soil sample to the top of the secondary cutting module 5, and the lifting plate 601 of the transport hoisting module 6 is lowered so that the shaped column soil sample is stuck between the lifting plate 601 and the bracket 529 (at this time, the enclosure blade 508 is as shown in FIG. Fig.17 The drill bit 602 is then raised to a higher height and reset, so that the drill bit 602 is separated from the shaped cylindrical soil sample; Afterwards, 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, so that the lifting seat 513 moves up and down along the vertical track seat 502, and then the cutting knife 506 moves to a suitable height, and the PLC controller controls the piston rod at the output end of the second electric cylinder 517 to extend, so that the two groups of cutting knives 506 approach each other until the cutting knives 506 contact the side of the shaping column soil sample; Then, the PLC controller controls the vibration motor 514 to work, so that the vibration block 520 drives the cutting knife 506 to move up and down quickly, so that the cutting knife 506 performs "flexible" cutting up and down on the shaped column soil sample; At the same time, the PLC controller controls the eighth motor 518 to work, and the eighth motor 518 drives the upper drive wheel 525 to rotate in the upper track groove 526, so that the upper drive wheel 525 drives the position of the cutting blade 506 to adjust (such as Fig.21 and 22 As shown), the cutting blade 506 cuts the shaped column soil sample into frozen soil sample blocks 9 of different sizes; After the frozen soil sample block 9 is obtained, the cutting blade 506 is moved and reset to the initial state, and then the lifting plate 601 of the transport hoisting module 6 is moved upward and reset to the initial state.
