[0004] During geological surveys, after sampling once, the sampling tube needs to be removed to collect and mark the samples, which is not convenient for sampling multiple layers of soil, so there is room for improvement. Summary of the invention

[0005] In order to improve the problem that it is inconvenient to sample multiple layers of soil at one time, the present application provides a soft soil geological survey device and survey method.

[0006] The survey method of a soft soil geological survey device provided in this application adopts the following technical solution: A soft soil geological survey device, comprising: a sampling cylinder into which soil can be inserted; A soil-breaking mechanism is arranged at the bottom of the sampling tube, and is used for drilling soil; A sampling assembly, rotatably connected to the sampling cylinder, the sampling assembly rotates to receive a portion of the soil in the sampling cylinder; A storage shell is fixed on the sampling tube, a receiving groove is provided on the side wall of the storage shell, and the sampling assembly is connected to the storage shell; A storage component is arranged on the storage shell and is used to receive the soil in the sampling component. The storage component includes a moving component and a plurality of storage boxes. The moving component is arranged on the storage shell. The plurality of storage boxes are stacked in sequence in the receiving groove along the vertical direction. The moving component is used to send the storage boxes to the well storage shell in sequence. The storage boxes are used to receive the soil.

[0007] By adopting the above technical solution, when in use, the sampling tube is aligned with the sampling point, and the soil breaking mechanism is started to drive the sampling tube and the storage shell to move down to the sampling layer. During this process, the soil enters the sampling tube from the bottom opening of the sampling tube, and then the storage component is used to send the soil in the sampling tube to the storage shell. At the same time, the storage box at the bottom of the receiving groove is moved out of the receiving groove, and then the moving component is started to drive the storage box at the bottom of the receiving groove into the storage shell to receive the soil in the receiving shell, and then the moving component is started again to make the storage box with the soil move down to the bottom of the storage shell for storage.

[0008] When the sampling tube moves in the soil, the soil in the sampling tube also moves and changes continuously. When the sampling tube reaches different sampling layers, the soil in the sampling tube is also the soil of the corresponding sampling layer. At this time, the sampling component is sent to the next storage shell, and then the storage box falls on the storage box at the bottom of the storage shell. The above steps are repeated so that several storage boxes are stacked in the storage shell in turn. After the sampling tube penetrates into the soil, multiple layers of soil can be sampled and stored at one time, which is convenient to operate.

[0009] Optionally, the soil-breaking mechanism includes a soil-breaking component and a driving component, the soil-breaking component is arranged at the bottom of the sampling cylinder, the soil-breaking component can move on the sampling cylinder along the length direction of the sampling cylinder, the driving component is arranged on the sampling cylinder, the driving component is connected to the soil-breaking component, and the driving component is used to drive the soil-breaking component to move to cut the soil.

[0010] By adopting the above technical solution, when working, the sampling tube is vertically aligned with the sampling point, and the driving component is started, so that the soil breaking component abuts against the soil and cuts the soil, thereby facilitating the sampling tube to be inserted into the soil, and then facilitating the sampling tube to reach the sampling layer for sampling.

[0011] Optionally, the soil-breaking assembly includes a mounting ring, which is coaxially embedded in the sampling tube, the bottom of the mounting ring extends out of the sampling tube, and a serrated bar is provided at the bottom of the mounting ring.

[0012] By adopting the above technical solution, when the sampling tube is aligned with the sampling point, the sawtooth bar abuts against the soil, and then the driving assembly is started to drive the mounting ring to rotate around the central axis of the sampling tube, thereby causing the sawtooth bar to rotate and achieve cutting of the soil, so that the sampling tube can penetrate deep into the soil.

[0013] Optionally, the driving component includes: A driving motor is arranged at the top of the sampling cylinder; A rotating gear is arranged in the sampling tube, the rotating gear is coaxially fixed with the output end of the driving motor, and the driving motor is used to drive the rotating gear to rotate; The transmission gear is coaxially embedded in the sampling tube, the transmission gear is meshed with the rotating gear, a plurality of connecting rods are passed through the transmission gear, one end of the connecting rod away from the transmission gear is fixed to the mounting ring, and the transmission gear rotates to drive the mounting ring to rotate.

[0014] By adopting the above technical solution, when the sawtooth bar is placed at the sampling point, the driving motor is started to drive the rotating gear to rotate, thereby driving the transmission gear to rotate, so that the connecting rod drives the mounting ring to rotate, thereby realizing the rotation of the sawtooth bar.

[0015] Optionally, a movable groove is provided on the side wall of the mounting ring, and a movable block is fixed in the sampling barrel. The movable block is inserted in the movable groove, and the connecting rod can move along the length direction of the sampling barrel on the transmission gear. The top end of the connecting rod extends out of the transmission gear and fixes a limiting block. When the mounting ring rotates, the movable block moves relatively in the movable groove to drive the mounting ring to move along the length direction of the sampling barrel.

[0016] By adopting the above technical scheme, when the mounting ring rotates under the cooperative transmission of the rotating gear and the transmission gear, the moving block moves relatively in the moving groove, and the trajectory of the moving groove fluctuates up and down, so that the moving block applies a thrust force to the inner wall of the moving groove. Because the height of the moving block is unchanged, each point of the moving groove must reach the height of the moving block, so that the mounting ring drives the connecting rod to move, and the limit block plays a limiting role, so that the connecting rod will not be separated from the transmission gear under the action of gravity, and then the mounting ring moves on the sampling barrel along the length direction of the sampling barrel, that is, the sawtooth bar continuously moves up and down during the rotation process, thereby realizing the vibrating rotation cutting of the sawtooth bar, further facilitating breaking the soil, and making it easier for the sampling barrel to accurately reach the sampling layer.

[0017] Optionally, the sampling component includes: A rotating rod, inserted in the sampling barrel, and capable of rotating in the sampling barrel; The sampling plate has a sampling hole extending through the side wall of the sampling plate, and the sampling hole is communicated with the sampling shell.

[0018] By adopting the above technical solution, when the sampling tube reaches the sampling layer, the sampling tube also contains the soil of the sampling layer. At this time, the rotating rod is driven to rotate, so that the sampling plate sweeps across the sampling tube. At this time, the soil in the sampling tube is squeezed by the sampling plate, so that the soil enters from the sampling hole on the side of the sampling plate, and then reaches the sampling shell along the sampling hole, thereby realizing the sampling and collection of the soil layer.

[0019] Optionally, the mobile component includes: A moving rod is inserted into the storage shell, the moving rod is arranged along the width direction of the sampling tube, and the rotating rod can rotate on the storage shell; The movable cylinder is coaxially fixed with the movable rod, one side of the movable cylinder is an opening structure, and the movable cylinder is communicated with the receiving groove for receiving the storage box in the receiving groove.

[0020] By adopting the above technical solution, when the soil in the sampling tube reaches the sampling shell through the sampling hole, the moving rod is driven to rotate, driving the opening of the moving tube toward the receiving groove, and the storage box at the bottom of the receiving groove rolls out of the receiving groove and falls into the moving tube through the opening of the moving tube, and then the moving rod is rotated so that the opening of the moving tube gradually faces the bottom of the storage shell, so that the storage box falls out of the moving tube and falls on the bottom of the storage shell to receive the soil that reaches the sampling shell. During the rotation of the moving tube, the opening of the moving tube is separated from the bottom of the receiving groove, and the side wall of the moving tube gradually turns to the receiving groove and abuts against the storage box at the bottom of the receiving groove to achieve the blocking of the receiving groove, so that the storage box cannot be moved out of the receiving groove and can only wait for the opening of the moving tube to rotate toward the receiving groove again.

[0021] Optionally, the storage box includes: Two mounting rings, the two mounting rings are arranged opposite to each other, the central axis of the mounting ring is parallel to the moving rod, and the side walls of the mounting rings are embedded with connecting blocks, and the connecting blocks can move on the mounting rings; A receiving box, the top of which is open, is used to receive the soil in the sampling plate, and the top corner of the receiving box is rotatably connected to the connecting block.

[0022] By adopting the above technical solution, the two mounting rings make the overall frame of the storage box similar to a cylinder, so that the storage box can adapt to the moving cylinder. When the moving cylinder is flipped, the receiving box moves on the mounting ring along the trajectory of the mounting ring, so that the receiving box remains open upward to receive soil.

[0023] Optionally, a counterweight is fixed to the bottom of the receiving box.

[0024] By adopting the above technical solution, the counterweight block increases the weight of the bottom of the receiving box, thereby increasing the stability of the receiving box so that it always keeps its opening upward under the action of gravity.

[0025] In a second aspect, the present application provides a survey method of a soft soil geological survey device, comprising the following steps: S1. Using the soil breaking mechanism to drive the sampling tube and the receiving shell to move down to the sampling layer, during which the soil enters the sampling tube from the bottom opening of the sampling tube; S2, then using the receiving assembly to deliver the soil in the sampling tube to the receiving shell; S3, then starting the moving component to drive the storage box at the bottom of the receiving groove into the storage shell to receive the soil, and finally the storage box receiving the soil is moved down to the bottom of the storage shell for storage; S4. When the sampling cylinder reaches different sampling layers, the soil in the sampling cylinder is also the soil of the corresponding sampling layer, and is then collected using a storage box, so that several storage boxes are stacked in sequence in the storage shell to achieve sampling and storage of multiple layers of soil.

[0026] In summary, the present application includes at least one of the following beneficial effects: 1. When in use, the soil-breaking mechanism is used to drive the sampling tube and the storage shell to move down to the sampling layer. During this process, the soil enters the sampling tube from the bottom opening of the sampling tube, and then the storage component is used to send the soil in the sampling tube to the storage shell. Then the moving component is started to drive the storage box at the bottom of the receiving groove to enter the storage shell to receive the soil. Finally, the storage box receiving the soil moves down to the bottom of the storage shell for storage.

When working, align the sampling tube vertically with the sampling point, start the driving assembly, make the soil-breaking assembly contact with the soil, and cut the soil, so as to facilitate the sampling tube to be inserted into the soil, and then facilitate the sampling tube to reach the sampling layer for sampling.

The sampling tube 10 is a hollow cylinder, and the sampling shell is fixed on the outer wall of the sampling tube 10. A soil-breaking component 21 is provided at the bottom of the sampling tube 10 to facilitate the sampling tube 10 to penetrate into the soil. A sampling component 30 is provided in the sampling tube 10, and the soil entering the sampling tube 10 can be sent to the sampling shell. A storage component 40 is provided in the storage shell 11. The storage component 40 includes a moving component 41 and a plurality of storage boxes 42. The moving component 41 is provided on the storage shell 11. The moving component 41 can sequentially send a single storage box 42 to the storage shell 11 and receive the soil entering the sampling shell. Finally, the plurality of storage boxes 42 are stacked in the receiving groove 111 in the vertical direction, so as to realize the layered sampling and storage of multiple layers of soil. A door that can be opened is installed on the top of the sampling shell to facilitate the taking and replenishment of the storage box 42.

[0031] Reference Figure 2 and Figure 3, wherein the earth-breaking mechanism 20 includes an earth-breaking component 21 and a driving component 22 , the earth-breaking component 21 includes a mounting ring 211 and a sawtooth bar 212 , and the driving component 22 includes a driving motor 221 , a rotating gear 222 and a transmission gear 223 . The driving motor 221 is installed in the wall thickness of the sampling barrel 10 by bolts, the rotating gear 222 is also located in the sampling barrel 10, and the rotating gear 222 is coaxially fixed with the output end of the driving motor 221, the transmission gear 223 is meshed with the rotating gear 222, and the interior of the transmission gear 223 is hollow and coaxial with the sampling barrel 10, the transmission gear 223 is also in the wall thickness of the sampling barrel 10, a plurality of connecting rods 224 are passed through the transmission gear 223, the connecting rods 224 are arranged along the length direction of the sampling barrel 10, the top end of the connecting rod 224 extends out of the transmission gear 223 and fixes a limit block 2241, the limit block 2241 limits the connecting rod 224 from sliding down out of the transmission gear 223, the bottom end of the connecting rod 224 is fixed to the mounting ring 211, the mounting ring 211 is coaxially embedded in the sampling barrel 10, and the bottom of the mounting ring 211 extends out of the sampling barrel 10 and is fixed to the sawtooth bar 212.

[0032] Reference Figure 2 and Figure 3 , wherein a wave-shaped moving groove 2111 is provided on the side wall of the mounting ring 211, and a moving block 12 is fixed in the wall thickness of the sampling tube 10. The moving block 12 is inserted into the moving groove 2111. When the sampling tube 10 is aligned with the sampling point, the sawtooth bar 212 abuts against the soil, and then the driving motor 221 is started to drive the rotating gear 222 to rotate, thereby driving the transmission gear 223 to rotate, so that the connecting rod 224 drives the mounting ring 211 to rotate, and the rotation of the sawtooth bar 212 is realized to cut the soil, so that the sampling tube 10 penetrates into the soil.

[0033] During the rotation of the mounting ring 211, the moving block 12 moves relatively in the moving groove 2111, and the trajectory of the moving groove 2111 fluctuates up and down, so that the moving block 12 applies a thrust to the inner wall of the moving groove 2111. Since the height of the moving block 12 remains unchanged, each point of the moving groove 2111 must reach the height of the moving block 12, so that the mounting ring 211 drives the connecting rod 224 to move up and down, and then the mounting ring 211 moves on the sampling barrel 10 along the length direction of the sampling barrel 10, that is, the sawtooth bar 212 continuously moves up and down during the rotation process, thereby realizing the vibrating rotation cutting of the sawtooth bar 212, further facilitating breaking the soil, and making it easier for the sampling barrel 10 to accurately reach the sampling layer.

[0034] Reference Figure 2The sampling assembly 30 includes a rotating rod 31 and a sampling plate 32. A motor is installed in the sampling tube 10. The output end of the motor is coaxially fixed with the rotating rod 31. The rotating rod 31 is vertically inserted in the sampling tube 10. The rotating rod 31 is fixed to the sampling plate 32. A sampling hole 321 is opened on the side wall of the sampling plate 32, and the sampling hole 321 is connected to the sampling shell.

[0035] When the sampling tube 10 reaches the sampling layer, the sampling tube 10 also contains the soil of the sampling layer. At this time, the rotating rod 31 is driven to rotate, so that the sampling plate 32 sweeps across the sampling tube 10. At this time, the soil in the sampling tube 10 is squeezed by the sampling plate 32, so that the soil enters from the sampling hole 321 on the side of the sampling plate 32, and then reaches the sampling shell along the sampling hole 321, so as to realize the sampling and collection of the soil layer.

[0036] Reference Figure 2 and Figure 4 The moving component 41 includes a moving rod 411 and a moving cylinder 412. A motor is embedded in the storage shell 11. The output end of the click is coaxially fixed with the moving rod 411. The moving rod 411 is arranged in the horizontal direction. The moving rod 411 is inserted in the storage shell 11. The moving rod 411 is arranged along the width direction of the sampling cylinder 10, and the rotating rod 31 can rotate on the storage shell 11. The moving cylinder 412 is coaxially fixed with the moving rod 411. One side of the moving cylinder 412 is an open structure. The moving cylinder 412 is connected to the receiving groove 111 for receiving the storage box 42 in the receiving groove 111.

[0037] When the soil in the sampling cylinder 10 reaches the sampling shell through the sampling hole 321, the moving rod 411 is driven to rotate, driving the opening of the moving cylinder 412 toward the receiving groove 111, and the storage box 42 at the bottom of the receiving groove 111 rolls out of the receiving groove 111 and falls into the moving cylinder 412 through the opening of the moving cylinder 412. Then the moving rod 411 is rotated to make the opening of the moving cylinder 412 gradually face the bottom of the storage shell 11, so that the storage box 42 falls out of the moving cylinder 412 and falls on the bottom of the storage shell 11 to receive the soil that reaches the sampling shell. When the movable cylinder 412 is rotating, the opening of the movable cylinder 412 is separated from the bottom of the receiving groove 111, and the side wall of the movable cylinder 412 gradually turns to the receiving groove 111 and abuts against the storage box 42 at the bottom of the receiving groove 111, thereby blocking the receiving groove 111, so that the storage box 42 cannot be moved out of the receiving groove 111 and can only wait for the opening of the movable cylinder 412 to rotate again toward the receiving groove 111.

[0038] Reference Figure 2 and Figure 4In order to adapt to the moving cylinder 412, the storage box 42 includes a receiving box 422 and two mounting rings 421. The top of the receiving box 422 is open, and the two mounting rings 421 are respectively located at both ends of the receiving box 422. The central axis of the mounting ring 421 is parallel to the moving rod 411. A connecting block 4221 is embedded on the side wall of the mounting ring 421.

The top angle of the receiving box 422 is rotatably connected to the connecting block 4221, and a counterweight is fixed to the bottom of the receiving box 422.

[0039] The two mounting rings 421 make the overall frame of the storage box 42 similar to a cylinder, so that the storage box 42 can adapt to the moving cylinder 412. When the moving cylinder 412 flips over, the counterweight block increases the weight of the bottom of the receiving box 422, so that the receiving box 422 moves along the trajectory of the mounting ring 421 on the mounting ring 421 under the action of gravity, ensuring that the receiving box 422 always keeps its opening facing upward to receive soil.

[0040] The implementation principle of a soft soil geological exploration device according to an embodiment of the present application is as follows: when in use, the sampling tube 10 is aligned with the sampling point, and the soil breaking mechanism 20 is started to drive the sampling tube 10 and the storage shell 11 to move down to the sampling layer. During this process, the soil enters the sampling tube 10 from the bottom opening of the sampling tube 10, and then the storage assembly 40 is used to send the soil in the sampling tube 10 to the storage shell 11. At the same time, the storage box 42 at the bottom of the receiving groove 111 is moved out of the receiving groove 111, and then the moving assembly 41 is started to drive the storage box 42 at the bottom of the receiving groove 111 to enter the storage shell 11 to receive the soil in the receiving shell 11, and then the moving assembly 41 is started again to move the storage box 42 with the soil down to the bottom of the storage shell 11 for storage.

[0041] When the sampling tube 10 moves in the soil, the soil in the sampling tube 10 also moves and changes continuously. When the sampling tube 10 reaches different sampling layers, the soil in the sampling tube 10 is also the soil of the corresponding sampling layer. At this time, the sampling component 30 is sent to the next storage shell 11, and then the storage box 42 falls on the storage box 42 at the bottom of the storage shell 11. The above steps are repeated so that several storage boxes 42 are stacked in the storage shell 11 in sequence. After the sampling tube 10 penetrates into the soil, multiple layers of soil can be sampled and stored at one time, and the operation is convenient.
