Description

Technical Field

[0001] The present invention belongs to the technical field of soil sampling, and specifically refers to a sampling device for layered soil inspection. Background Art

[0002] When detecting soil components, the conventional procedure is to collect soil samples at different depths at multiple sampling points in one trip and send them to the laboratory for analysis together after sampling; in the prior art, for example, invention patents with publication numbers such as CN115628940A are all for vertical drilling and full-depth sampling. Due to the need to balance multiple factors such as drill bit strength and sampling volume, the current mainstream hollow sampling drill bit has a diameter of about 100 mm, and the length varies from one meter to several meters according to the sampling depth; however, when analyzing in the laboratory, such a large sample volume is not required. Generally, it is only necessary to sample the soil layer at continuous depths; therefore, if the samples can be sampled and stored in layers on-site after sampling, it will greatly reduce the weight and space occupied by the samples and relieve the transportation pressure during sampling. Summary of the Invention

[0003] In view of the above situation, to overcome the defects of the prior art, the present invention provides a sampling device that can sample and store samples in layers on-site after sampling; by intermittently extracting samples in a sampling cylinder with full depth, it can not only meet the requirements of subsequent laboratory analysis but also greatly reduce the volume and weight of the samples; by arranging soil samples and hard partitions alternately in the sample storage cylinder, it can prevent the soil samples from different layers from mixing with each other and affecting the subsequent analysis results; by raising and lowering the drilling and sampling assembly, not only can the soil samples be taken out from the deep underground, but also it can cooperate with the rotating assembly to automatically complete the filling of the soil samples and the intermittent arrangement of the hard partitions.

[0004] The technical solution adopted by the present invention is as follows: The present invention provides a sampling device for layered soil inspection, including a partitioned sample container, a turntable mechanism, a rotary sampling mechanism, and a mobile sampling platform. The rotary sampling mechanism is arranged on the mobile sampling platform. The turntable mechanism includes a transverse movement component and a rotation component. The transverse movement component is arranged on the mobile sampling platform, and the rotation component is arranged on the transverse movement component. The partitioned sample container is arranged on the transverse movement component.

[0005] Furthermore, the partitioned sample container includes a sample storage cylinder. A piston is slidably clamped in the sample storage cylinder. Soil samples and hard partitions are alternately arranged above the piston. The hard partitions can separate soil samples at different depths.

[0006] There is resistance when the piston slides in the sample storage cylinder. The piston will not slide under the action of the gravity of the soil sample. However, by lowering the drilling and sampling assembly, the position of the piston can be adjusted. By gradually sliding the piston, it is possible to extract specific layers and load them into the sample storage cylinder at a relatively long sampling height in the sampling cylinder, which can greatly reduce the weight and space occupied by the sample. Moreover, the soil samples of different layers are separated by hard partitions, which can prevent the soil samples of different layers from mixing with each other.

[0007] Furthermore, the transverse movement assembly includes a transverse movement slide rail and a transverse movement slide plate. The transverse movement slide rail is arranged on the mobile sampling platform, and the transverse movement slide plate is clamped and slidably arranged on the transverse movement slide rail. Limit locking mechanisms capable of controlling the position of the transverse movement slide plate are arranged at both ends of the transverse movement slide rail. A container mounting hole is arranged on the transverse movement slide plate, and the sample storage cylinder is detachably arranged in the container mounting hole.

[0008] By locking and unlocking the transverse movement assembly, the position adjustment of the rotation assembly can be allowed, so that during the drilling process, the rotation assembly can be displaced to avoid the drilling and sampling assembly. During the sample transfer stage, the compartmentalized sample container can be pushed directly below the sampling cylinder.

[0009] Preferably, the rotation assembly includes a rotation motor, a disc-shaped turntable, and an annular plate. The rotation motor is arranged on the transverse movement assembly, the disc-shaped turntable is fixedly connected to the rotating part of the rotation motor, and partition rods are annularly and evenly arranged on the disc-shaped turntable. The disc-shaped turntable is divided into fan-shaped areas by the partition rods. The annular plate is arranged on the disc-shaped turntable, and the hard partitions are annularly and evenly arranged in the annular plate, and the hard partitions are located in the above-mentioned fan-shaped areas.

[0010] In the initial state, the hard partition is pre-fixed in the circular hole of the annular plate. The pre-fixing method can be interference fit or spot connection, etc., as long as it is ensured that the hard partition can be integrally pushed out of the annular plate by the lowering of the sampling cylinder.

[0011] By rotating the disc-shaped turntable and the annular plate, the hard partitions can be continuously supplied, so as to realize the alternating distribution of the soil samples and the hard partitions in the sample storage cylinder.

[0012] As a further preference of the present invention, a discharge hole is also arranged on the annular plate, and soil particles can be discharged through the discharge hole.

[0013] By rotating the disc-shaped turntable and the annular plate, the top of the sample storage cylinder can be cleaned and leveled, so that all the soil samples higher than the sample storage cylinder are pushed to the outside.

[0014] Further, the rotary sampling mechanism includes a drilling and sampling assembly and a driving assembly. The drilling and sampling assembly includes a sampling cylinder and a helical blade. The sampling cylinder is arranged vertically, and the helical blade is rotatably arranged in the sampling cylinder. The lifting and lowering of the sampling cylinder and the rotation of the helical blade can be controlled by the driving assembly.

[0015] Preferably, the drilling and sampling assembly further includes a guiding bracket. The guiding bracket is arranged on the mobile sampling platform. A guiding sliding hole is provided on the guiding bracket. The sampling cylinder is longitudinally slidably arranged in the guiding sliding hole. A cutting edge for cutting soil is provided at the bottom of the sampling cylinder. A central shaft is provided at the central position of the helical blade, and a pointed head for drilling into the soil is provided at the bottom of the central shaft.

[0016] The rotation speed of the helical blade matches the descending speed of the sampling cylinder. The rotation and descent of the helical blade in the soil are similar to the rotary drilling of a screw in a material. Under this working condition, the soil moves translationally along the sampling cylinder, and the helical blade will not mix and stir the soil.

[0017] As a further preference of the present invention, the driving assembly includes a vertical column and a lifting platform. The vertical column is arranged on the mobile sampling platform. The lifting platform is slidably arranged on the vertical column, and a cantilever part is provided on the lifting platform.

[0018] Preferably, a clamping table is provided at the top of the sampling cylinder, and a clamping part connected to the clamping table is provided on the cantilever part. The sampling cylinder can be lifted and lowered by the lifting platform.

[0019] As a further preference of the present invention, the driving assembly further includes a drilling motor. The drilling motor is arranged on the cantilever part. A connecting shaft is provided at the top of the central shaft. A through hole is provided at the center of the clamping part. The connecting shaft passes through the through hole and is connected to the output shaft of the drilling motor. The helical blade can be rotated by the drilling motor.

[0020] Through the lifting and lowering of the sampling cylinder and the rotation of the helical blade, not only can the soil underground be sampled, but also through cooperation with the rotating assembly, the layered storage of the soil in the sample storage cylinder can be realized.

[0021] Further, the mobile sampling platform includes a platform bottom plate and a traveling mechanism. An avoidance groove is provided on the platform bottom plate. The sample storage cylinder is located in the avoidance groove. The transverse translation slide rail, the guiding bracket and the vertical column are arranged on the platform bottom plate. The traveling mechanism is arranged below the platform bottom plate, and traveling wheels are provided at both ends of the traveling mechanism.

[0022] A braking mechanism is provided on the traveling mechanism, which can improve the stability of the mobile sampling platform during the sampling process.

[0023] The beneficial effects achieved by the present invention with the above structure are as follows:

[0024] (1) There is resistance when the piston slides in the sample storage cylinder. The piston will not slide under the action of the gravity of the soil sample. However, by lowering the drilling and sampling assembly, the position of the piston can be adjusted. By gradually sliding the piston, a specific layer can be extracted and loaded into the sample storage cylinder at a relatively long sampling height in the sampling cylinder, which can greatly reduce the weight and space occupied by the sample. Moreover, the soil samples of different layers are separated by a hard partition, which can prevent the soil samples of different layers from mixing with each other.

[0025] (2) By locking and unlocking the transverse movement assembly, the rotation assembly can be allowed to adjust its position, so as to avoid the position of the drilling and sampling assembly during the drilling process through the transverse movement of the rotation assembly. During the sample transfer stage, the partitioned sample container can be pushed directly below the sampling cylinder.

[0026] (3) In the initial state, the hard partition is pre-fixed in the circular hole of the annular plate. The pre-fixing method can be interference fit or spot connection, etc., as long as it is ensured that the hard partition can be pushed out of the annular plate as a whole by lowering the sampling cylinder.

[0027] (4) By rotating the disc-shaped turntable and the annular plate, the hard partition can be continuously supplied, so as to realize the alternating distribution of the soil sample and the hard partition in the sample storage cylinder.

[0028] (5) By rotating the disc-shaped turntable and the annular plate, the top of the sample storage cylinder can be cleaned and leveled, so that all the soil samples higher than the sample storage cylinder are pushed to the outside.

[0029] (6) The rotation speed of the spiral blade matches the lowering speed of the sampling cylinder. The rotation and lowering of the spiral blade in the soil is similar to the rotary drilling of a screw in a material. Under this working condition, the soil moves translationally along the sampling cylinder, and the spiral blade will not mix and stir the soil and will not damage the original soil layer structure.

[0030] (7) By raising and lowering the sampling cylinder and rotating the spiral blade, not only can the underground soil be sampled, but also through cooperation with the rotation assembly, the layered storage of the soil in the sample storage cylinder can be realized.

[0044] The accompanying drawings are used to provide a further understanding of the present invention, and constitute a part of the specification. Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation to the present invention. Detailed implementation mode

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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 work belong to the scope of protection of the present invention.

[0046] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0047] As Figures 1 to 11 shown, the present invention proposes a sampling device for layered soil inspection, which includes a partitioned sample container 1, a turntable mechanism 2, a rotary sampling mechanism 3 and a mobile sampling platform 4. The rotary sampling mechanism 3 is arranged on the mobile sampling platform 4. The turntable mechanism 2 includes a transverse movement component 8 and a rotation component 9. The transverse movement component 8 is arranged on the mobile sampling platform 4, and the rotation component 9 is arranged on the transverse movement component 8. The partitioned sample container 1 is arranged on the transverse movement component 8.

[0048] The partitioned sample container 1 includes a sample storage cylinder 5. A piston 39 is slidably engaged in the sample storage cylinder 5. Soil samples 6 and hard partitions 7 are alternately arranged above the piston 39. Different depths of soil samples 6 can be separated by the hard partitions 7.

[0049] There is resistance when the piston 39 slides in the sample storage cylinder 5, and the piston 39 will not slide under the action of the gravity of the soil sample 6. However, by the descent of the drilling sampling component 18, the position of the piston 39 can be adjusted. By gradually sliding the piston 39, specific layers can be extracted and loaded into the sample storage cylinder 5 at a longer sampling height of the sampling cylinder 21, which can greatly reduce the weight and space occupied by the samples. And different layers of soil samples 6 are separated by the hard partitions 7, which can avoid the mixing of different layers of soil samples 6.

[0050] The transverse movement component 8 includes a transverse movement slide rail 10 and a transverse movement slide plate 11. The transverse movement slide rail 10 is arranged on the mobile sampling platform 4. The transverse movement slide plate 11 is slidably engaged on the transverse movement slide rail 10. Limit locking mechanisms capable of controlling the position of the transverse movement slide plate 11 are arranged at both ends of the transverse movement slide rail 10. A container mounting hole 15 is arranged on the transverse movement slide plate 11, and the sample storage cylinder 5 is detachably arranged in the container mounting hole 15.

[0051] By locking and unlocking the transverse movement component 8, the rotation component 9 can be allowed to adjust its position, so as to avoid the position of the drilling and sampling component 18 through the transverse movement of the rotation component 9 during the drilling process. During the sample transfer stage, the layered sample container 1 can be pushed directly below the sampling cylinder 21.

[0052] The rotation component 9 includes a rotation motor 12, a disc-shaped turntable 13 and an annular plate 14. The rotation motor 12 is arranged on the transverse movement component 8. The disc-shaped turntable 13 is fixedly connected to the rotation part of the rotation motor 12. The disc-shaped turntable 13 is annularly and evenly provided with partition rods 16. The disc-shaped turntable 13 is divided into fan-shaped areas by the partition rods 16. The annular plate 14 is arranged on the disc-shaped turntable 13. The hard partition plates 7 are annularly and evenly arranged in the annular plate 14, and the hard partition plates 7 are located in the above-mentioned fan-shaped areas.

[0053] In the initial state, the hard partition plate 7 is pre-fixed in the circular hole of the annular plate 14. The pre-fixing method can be interference fit or spot connection, etc., as long as it is ensured that the hard partition plate 7 can be integrally pushed out of the annular plate 14 by the downward movement of the sampling cylinder 21.

[0054] By rotating the disc-shaped turntable 13 and the annular plate 14, the hard partition plates 7 can be continuously supplied, so as to realize the alternating distribution of the soil samples 6 and the hard partition plates 7 in the sample storage cylinder 5.

[0055] The annular plate 14 is also provided with a discharge hole 17, and the soil particles can be discharged through the discharge hole 17.

[0056] By rotating the disc-shaped turntable 13 and the annular plate 14, the top of the sample storage cylinder 5 can be cleaned and leveled, so that all the soil samples 6 higher than the sample storage cylinder 5 are pushed to the outside.

[0057] The rotary sampling mechanism 3 includes a drilling and sampling component 18 and a driving component 19. The drilling and sampling component 18 includes a sampling cylinder 21 and a spiral blade 22. The sampling cylinder 21 is arranged vertically. The spiral blade 22 is rotatably arranged in the sampling cylinder 21. The lifting and rotation of the sampling cylinder 21 can be controlled by the driving component 19.

[0058] The drilling and sampling component 18 further includes a guiding bracket 20. The guiding bracket 20 is arranged on the mobile sampling platform 4. The guiding bracket 20 is provided with a guiding sliding hole 26. The sampling cylinder 21 is longitudinally slidably arranged in the guiding sliding hole 26. The bottom of the sampling cylinder 21 is provided with a cutting edge 28 for cutting soil. The center position of the spiral blade 22 is provided with a central shaft 29, and the bottom of the central shaft 29 is provided with a pointed head 30 for drilling into the soil.

[0059] The rotation speed of the spiral blade 22 matches the descending speed of the sampling cylinder 21. The rotation and descent of the spiral blade 22 in the soil is similar to the rotary drilling of a screw in a material. Under this working condition, the soil moves translationally along the sampling cylinder 21, and the spiral blade 22 does not mix and stir the soil.

[0060] The drive assembly 19 includes a vertical column 23 and a lifting platform 24. The vertical column 23 is arranged on the mobile sampling platform 4, the lifting platform 24 is slidably arranged on the vertical column 23, and a cantilever portion 32 is arranged on the lifting platform 24.

[0061] A clamping platform 27 is arranged at the top of the sampling cylinder 21, and a clamping portion 33 connected to the clamping platform 27 is arranged on the cantilever portion 32. The sampling cylinder 21 can be lifted and lowered by the lifting platform 24.

[0062] The drive assembly 19 further includes a drilling motor 25. The drilling motor 25 is arranged on the cantilever portion 32. A connecting shaft 31 is arranged at the top of the central shaft 29. A through hole 38 is arranged at the center of the clamping portion 33. The connecting shaft 31 passes through the through hole 38 and is connected to the output shaft of the drilling motor 25. The spiral blade 22 can be rotated by the drilling motor 25.

[0063] Through the lifting of the sampling cylinder 21 and the rotation of the spiral blade 22, not only can the soil underground be sampled, but also through the cooperation with the rotating assembly 9, the layered storage of the soil in the sample storage cylinder 5 can be realized.

[0064] The mobile sampling platform 4 includes a platform bottom plate 34 and a traveling mechanism 35. An avoidance groove 36 is arranged on the platform bottom plate 34. The sample storage cylinder 5 is located in the avoidance groove 36. The transverse translation slide rail 10, the guiding bracket 20 and the vertical column 23 are arranged on the platform bottom plate 34. The traveling mechanism 35 is arranged below the platform bottom plate 34, and traveling wheels 37 are arranged at both ends of the traveling mechanism 35.

[0065] A braking mechanism is arranged on the traveling mechanism 35, which can improve the stability of the mobile sampling platform 4 during the sampling process.

[0066] As Figure 12 shown, the vertical square represents the sampling cylinder 21, and the sampling cylinder 21 is filled with soil. Since the soil enters the sampling cylinder 21 translationally, the distribution state of the soil in the sampling cylinder 21 is the same as that underground at this time; when storing, the sampling and layering method is adopted, which can not only study the soil at different depths, but also greatly reduce the sample size and relieve the burden of transportation and storage; the areas with diagonal hatching in the figure represent the layer areas to be retained, and the remaining areas represent the layer areas not to be retained; parameters such as the position, layer height, and interval of the retained layer areas can be freely controlled.

[0067] During specific use, first, the user needs to transfer the platform bottom plate 34 to the designated position through the traveling mechanism 35, and then fix the position of the platform bottom plate 34 through the parking device. In the initial state, the transverse sliding plate 11 is located at one end of the transverse sliding rail 10 far from the rotary sampling mechanism 3. At this time, the lifting platform 24 can be lowered along the vertical column 23 to drive the sampling cylinder 21 to descend and insert into the soil, so that the soil enters the interior of the sampling cylinder 21;

[0068] Meanwhile, the rotation of the helical blade 22 is controlled by the drilling motor 25, and the rotation speed of the helical blade 22 matches the descending speed of the sampling cylinder 21. The rotation and descent of the helical blade 22 in the soil is similar to the rotary drilling of a screw in a material. Under this working condition, the soil moves translationally along the sampling cylinder 21, and the helical blade 22 does not mix and stir the soil.

[0069] After sampling is completed, without rotating the vertical column 23, the sampling cylinder 21 and the helical blade 22 are integrally withdrawn by the rising of the lifting platform 24. At this time, the soil in the sampling cylinder 21 will be taken out together, completing the overall sampling.

[0070] Then, the rotating assembly 9 is transferred to one end close to the rotary sampling mechanism 3 by the sliding of the transverse sliding plate 11. At this time, the sample storage cylinder 5 is located directly below the sampling cylinder 21.

[0071] Then, the lifting platform 24 is used to push the sampling cylinder 21 downward. When the sampling cylinder 21 abuts against the hard partition 7 on the annular plate 14, the hard partition 7 will be detached from the annular plate 14 and enter the sample storage cylinder 5. Then, continue to push. When the hard partition 7 abuts against the piston 39, it will drive the piston 39 to slide downward together. The sampling depth of the sample storage cylinder 5 can be controlled by the descending amplitude of the hard partition 7;

[0072] After the sampling cylinder 21 stops descending, the soil in the sampling cylinder 21 can be gradually discharged by rotating the helical blade 22 in the reverse direction by the drilling motor 25. The reverse rotation of the helical blade 22 can occur during the ascending and resetting process of the sampling cylinder 21, or it can occur after the sampling cylinder 21 ascends and resets. The sampling cylinder 21 is reset to a height slightly higher than the dish-shaped turntable 13;

[0073] When the helical blade 22 rotates in the reverse direction, the lower-layer soil will fall onto the hard partition 7 and accumulate in the sample storage cylinder 5. This part corresponds to Figure 12 the depth range with diagonal hatching; until the soil is higher than the upper opening of the sample storage cylinder 5, a small soil slope will continue to accumulate, and the subsequent falling soil will fall outside along the soil slope. This part corresponds to Figure 12 the depth range without diagonal hatching.

[0074] When the next storage layer reaches the bottom opening of the sampling cylinder 21, the spiral blade 22 is paused, and then the motor 12 is rotated to drive the disc-shaped turntable 13 and the annular plate 14 to rotate by a unit angle. During the rotation, the disc-shaped turntable 13 and the annular plate 14 can level the small soil slope accumulated at the opening of the sample storage cylinder 5. At this time, the new hard partition 7 is just located at the top opening of the sample storage cylinder 5. Pressing down the sampling cylinder 21 can make the new hard partition 7 detach from the annular plate 14 and enter the sample storage cylinder 5. At the same time, the soil sample 6 and the hard partition 7 already in the sample storage cylinder 5, together with the piston 39, are pressed down by a certain amplitude again.

[0075] By repeatedly executing the above steps, intermittent sampling and storage of the soil sample 6 within the entire sampling depth range can be achieved, and the soil samples 6 in different layers are separated by the hard partition 7 to avoid mixing.

[0076] Parameters such as the positions, layer heights, and intervals of the retention layer area and the sub-retention layer area can all be flexibly controlled.

[0077] In the second embodiment, the annular plate 14 can be arranged above the disc-shaped turntable 13. At this time, when the partition rod 16 rotates, a better leveling effect can be achieved at the opening of the sample storage cylinder 5, and all the soil samples 6 higher than the sample storage cylinder 5 are pushed to the outside.

[0078] In the third embodiment: The hard partition 7 can be pre-fixed in the annular plate 14 by interference fit, or by a dotted line connection similar to that of toilet paper or a fresh-keeping bag, but it is necessary to ensure that the hard partition 7 can fall off the annular plate 14 as a whole when it is stamped.

[0079] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0080] The above describes the present invention and its embodiments. This description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural modes and embodiments without creative efforts without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
