Description

Technical Field

[0001] The invention relates to the technical field of soil filling sampling, in particular to a soil sampling device for soil filling. Background Art

[0002] Backfill refers to the process of placing soil, stone, and other materials into a designated area manually or mechanically to raise the ground, level the site, or form a roadbed or foundation for a structure. Backfill is a common construction process in civil engineering, construction, road engineering, water conservancy, and other fields, and plays a key role in the stability, load-bearing capacity, and usability of the project.

[0003] Before filling, soil sampling is required in designated areas. This is directly related to the stability and safety of subsequent structures such as buildings and roads. Through soil sampling and analysis, the physical and mechanical properties of the fill soil, such as particle composition, moisture content, density, and bearing capacity, can be understood, thereby providing a scientific basis for fill design and construction, ensuring that the fill body can meet the project requirements. If soil sampling is not carried out and unqualified soil materials are blindly used for filling, it may lead to uneven settlement of the fill body, landslides and other engineering accidents, causing serious safety hazards and economic losses to the project.

[0004] For example, when filling on a soft soil foundation, if the properties and thickness of the soft soil are not understood and appropriate treatment measures are not taken, large settlement may occur after filling, affecting the normal use of the superstructure.

[0005] The Chinese patent with announcement number CN114323772B discloses a portable geographic information collection device, which relates to the field of geographic information collection technology, including a placement box and a collection mechanism. The outer wall of the placement box is provided with a portable mechanism, and the bottom of the skateboard is provided with an auxiliary mechanism. The present invention drives it to slide through the pull rod and the universal wheel at the bottom of the placement box, or two staff members stand on both sides of the placement box and carry the device through the carrying handles. The above design can meet the requirements of sliding on the ground and carrying the placement box, which is convenient to carry. The frame rod drives the skateboard to rotate a certain angle, and a new drill barrel is used to take soil sampling at another point through a high-frequency electric cylinder. Repeating the operation can perform soil sampling at multiple points, and then the sampled soil is mixed and analyzed, so that the soil data after collection is more representative and the accuracy of the collected soil data is improved.

[0006] However, the above patent has the following shortcomings:

[0007] The above patent uses a high-frequency electric cylinder installed on the drill tube to take samples. However, in actual use, the high-frequency electric cylinder will shake the soil in the drill tube into a loose state. The loose soil may be mixed, resulting in unclear soil stratification boundaries.

[0008] When the soil in the drill tube needs to be taken out, workers need to spend a lot of time and effort, and the taken out soil is difficult to keep in one piece, which leads to sampling failure;

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0047] See also Figures 1-10 The present invention provides a technical solution: a soil sampling device for soil filling, comprising a table 1, a first frame 2 is vertically installed on the top of the table 1, a first lifting plate 3 is arranged above the table 1, and a punching sampling assembly is arranged on the first lifting plate 3, a second frame 4 is vertically installed on the top of the first lifting plate 3, and a compression assembly is arranged on the second frame 4, a drill tube 5 is arranged at the bottom of the first lifting plate 3, and an auxiliary compaction assembly is arranged in the drill tube 5, a rectangular plate 10 is symmetrically installed at the bottom of the table 1, and a cleaning assembly is arranged on the rectangular plate 10, an L-shaped body 6 is arranged on the top of the table 1, and a flattening assembly is arranged on the L-shaped body 6, rectangular tubes 7 are vertically installed at the four corners of the bottom of the table 1, and a height adjustment assembly is arranged in the rectangular tube 7, a supporting and fixing assembly is arranged on the outer wall of the table 1, and a circular hole 16 is opened through the top of the table 1;

[0048] The compression assembly includes a second lifting plate 27, a fifth electric push rod 28, and a cylinder 29. The fifth electric push rod 28 is vertically installed on the top of the second frame 4, and the second lifting plate 27 is installed on the output end of the fifth electric push rod 28. The cylinder 29 is vertically rotatably installed at the bottom of the second lifting plate 27, and a threaded column 42 is installed at the bottom of the cylinder 29. The threaded column 42 movably passes through the circular tube 23 and extends into the drill pipe 5. The outer thread of the threaded column 42 is engaged with the internal threaded tube 35.

[0049] Specifically, when it is necessary to compress the soil sampled in the drill barrel 5, the fifth electric push rod 28 vertically installed on the second frame 4 is started to push the second lifting plate 27 downward, and the cylinder 29 is driven downward by the second lifting plate 27. When the threaded column 42 installed at the bottom of the cylinder 29 penetrates the circular tube 23 and extends into the internal threaded tube 35 installed at the top of the circular body 34, the rotation drive of the cylinder 29 is immediately stopped. The rotation of the cylinder 29 is only to thread the threaded column 42 into the threaded tube 35, and then the fifth electric push rod 28 is continuously driven to push the circular body 34 downward to compress the soil in the drill barrel 5, thereby ensuring that the soil maintains its integrity after being taken out from the drill barrel 5, preventing the taken out soil from being broken and affecting the sampling results. When the cylinder 29 is inserted into the drill barrel 5, the drill barrel 5 does not rotate, and the circular tube 23 and the cylinder 29 do not contact.

[0050] Furthermore, a fourth motor 43 is installed at the bottom of the second lifting plate 27, and a fourth gear 31 is installed at the output end of the fourth motor 43. The outer side of the fourth gear 31 is meshed with the third gear 30, and the third gear 30 is sleeved and installed on the outer side of the cylinder 29.

[0051] Specifically, when it is necessary to thread the threaded column 42 into the internal threaded tube 35, the threaded column 42 is driven downward by the downward-moving cylinder 29 to move into the bowl-shaped guide shell 36. The threaded column 42 can be introduced into the internal threaded tube 35 through the shape of the bowl-shaped guide shell 36. Then the fourth motor 43 is started to drive the fourth gear 31 to rotate, and the rotating fourth gear 31 drives the third gear 30 to rotate. The rotating third gear 30 drives the cylinder 29 to rotate, and then the threaded column 42 can be threadedly installed in the threaded tube 35. Then the fourth motor 43 is stopped, and then the circular body 34 can be driven downward by the cylinder 29. During the rotation of the cylinder 29, the fifth electric push rod 28 is also required to push it to move downward. The threaded column 42 can be installed in the internal threaded tube 35 through the cooperation of the fifth electric push rod 28 and the fourth motor 43.

[0052] Furthermore, the punching sampling assembly includes a circular tube body 23, a third motor 24, a first gear 25 and a second gear 26. A sixth electric push rod 44 is vertically symmetrically installed on the top of the first frame 2, and the output ends of the sixth electric push rod 44 are both installed on the top of the first lifting plate 3. First guide grooves 38 are vertically opened on both side walls of the first frame 2, and first guide blocks 39 are slidably installed in the first guide grooves 38. The first guide blocks 39 are all installed on the outside of the first lifting plate 3. The top of the first lifting plate 3 vertically rotates through the circular tube body 23, and the drill barrel 5 is installed at the bottom of the circular tube body 23. The outside of the circular tube body 23 is fixedly sleeved with a second gear 26, and the outside of the second gear 26 is meshed with the first gear 25. The top of the first lifting plate 3 is installed with a third motor 24, and the output end of the third motor 24 passes through the first lifting plate 3 and is installed with the first gear 25;

[0053] Specifically, when sampling is required, the sixth electric push rod 44 is started to drive the first lifting plate 3 to move downward. During the downward movement of the first lifting plate 3, the third motor 24 is started to drive the first gear 25 to rotate. The rotating first gear 25 drives the second gear 26 engaged with it to rotate, and the second gear 26 drives the circular tube 23 to rotate. When the circular tube 23 rotates, it drives the drill barrel 5 to rotate. Sampling can be achieved by moving the rotating drill barrel 5 downward. The rotating drill barrel 5 can solve the problem of loosening the soil caused by vibration, which leads to soil mixing.

[0054] Furthermore, the auxiliary compaction assembly includes a guide rod 32, a spring 33 and a circular body 34. The circular body 34 is movably arranged in the drill barrel 5, and an internally threaded tube 35 is installed on the top of the circular body 34. A bowl-shaped guide shell 36 is installed on the top of the internally threaded tube 35. A plurality of guide rods 32 are vertically installed on the top of the circular body 34, and the tops of the guide rods 32 all slide through the top of the drill barrel 5. The outside of the guide rods 32 are all sleeved with springs 33, and the springs 33 are located in the drill barrel 5.

[0055] Specifically, during the sampling process of the drill tube 5, the circular body 34 is pushed downward by the cooperation of the guide rod 32 and the spring 33 to pressurize the top of the sampled soil, ensuring that the top of the soil is always in a pressurized and restricted state during the sampling process to prevent the top of the soil from becoming loose.

[0056] Furthermore, the cleaning assembly includes a screw 11, a second motor 12 and a first electric push rod 14. The screw 11 is rotatably installed between the rectangular plates 10, and the outer side of the screw 11 is threadedly engaged with a threaded block 13. The first electric push rod 14 is vertically installed on the top of the threaded block 13, and a scraper 15 is installed at the output end of the first electric push rod 14. The second motor 12 is installed on the outer side of the rectangular plate 10, and the second motor 12 is used to drive the screw 11 to rotate;

[0057] Specifically, when the sampling ground needs to be cleaned, the first electric push rod 14 is started to push the scraper 15 down and insert it into the loose soil layer on the ground, and then the second motor 12 is started to drive the screw rod 11 to rotate, and the rotating screw rod 11 drives the threaded block 13 to move horizontally, and the threaded block 13 drives the scraper 15 to move, so that the loose soil can be pushed to the side position of the bottom of the table 1. A guide tube is installed on the top of the scraper 15, and a guide column is slidably inserted into the guide tube. The top of the guide column is installed to the bottom of the threaded block 13, which can improve the stability of the scraper 15 when it is working.

[0058] Furthermore, the flattening assembly includes a second electric push rod 17 and a hole expansion protection body 18. An L-shaped body 6 is vertically installed on both sides of the circular hole 16 on the top of the table 1, and a second electric push rod 17 is vertically installed on the top of the L-shaped body 6. The output end of the second electric push rod 17 is installed on the top of the hole expansion protection body 18, and the hole expansion protection body 18 is located in the circular hole 16.

[0059] Specifically, when it is necessary to position and flatten the cleaned ground, the second electric push rod 17 is driven to move the hole expansion protection body 18 downward, and the bottom of the hole expansion protection body 18 is inserted into the soil. The top position of the hole expansion protection body 18 can flatten the surrounding soil, and then the downward-moving drill tube 5 passes through the hole expansion protection body 18 and is inserted into the soil for sampling. The hole expansion protection body 18 can be used to position and restrict the top of the ground, so that the sampling port is in a protected state to prevent the hole from collapsing during the sampling process.

[0060] Furthermore, the height adjustment assembly includes a fourth electric push rod 21 and a lifting column 22. The fourth electric push rod 21 is vertically installed at the top of the rectangular tube 7, and the lifting column 22 is installed at the output end of the fourth electric push rod 21. The top of the lifting column 22 is slidably inserted into the bottom of the rectangular tube 7, and the bottom of the lifting column 22 is installed with a wheel 37.

[0061] Specifically, when the table top 1 needs to be moved, the fourth electric push rod 21 is started to push the lifting column 22 slidably inserted in the rectangular tube 7 downward, and the wheels 37 installed at the bottom of the lifting column 22 contact the ground, thereby supporting the auger drill bit support legs 9 to ensure that the auger drill bit support legs 9 do not contact the ground, and then the table top 1 can be moved.

[0062] Furthermore, the supporting and fixing assembly includes an auger drill bit support leg 9 and a first motor 8. The four corners of the bottom of the table 1 are vertically rotatably mounted with an auger drill bit support leg 9. A plurality of first motors 8 are mounted on the top of the table 1, and the first motors 8 are used to drive the auger drill bit support legs 9 to rotate.

[0063] Specifically, when sampling is required, the wheels 37 are retracted to make the auger drill bit support legs 9 contact the ground, and the table top 1 can be supported by the four auger drill bit support legs 9. Then, the first motor 8 is started at the same time to drive the auger drill bit support legs 9 to rotate. When the bottoms of the auger drill bit support legs 9 are rotated and drilled into the soil, the table top 1 can be fixed in the soil to ensure the stability of the table top 1 during operation.

[0064] Furthermore, a third electric push rod 19 is installed horizontally on the top of the table 1, and a support plate 20 is installed at the output end of the third electric push rod 19;

[0065] Specifically, when the soil in the drill barrel 5 needs to be compressed, the third electric push rod 19 is started to drive the support plate 20 to move to the top of the hole expansion protective body 18, and then the bottom of the drill barrel 5 is moved down to contact the top of the support plate 20, providing conditions for the circular body 34 to move down to squeeze the soil.

[0066] Furthermore, second guide grooves 40 are vertically opened on both sides of the second frame 4, and second guide blocks 41 are slidably installed in the second guide grooves 40, and the second guide blocks 41 are installed on the outside of the second lifting plate 27;

[0067] Specifically, during the up and down movement of the second lifting plate 27 , the second guide block 41 installed thereon slides in the second guide groove 40 , thereby improving the stability of the up and down movement of the second lifting plate 27 and ensuring the stability of the up and down movement of the cylinder 29 .

[0068] Working principle: When using the soil sampling device for soil filling, the table 1 is placed in a suitable position, and the auger drill bit support leg 9 is moved down to contact the ground, and then the first motor 8 is started at the same time to drive the auger drill bit support leg 9 to rotate. When the bottom of the auger drill bit support leg 9 rotates and drills into the soil, the first electric push rod 14 is started to push the scraper 15 to move down and insert it into the loose soil layer on the ground, and then the second motor 12 is started to drive the screw rod 11 to rotate, and the rotating screw rod 11 drives the threaded block 13 to move horizontally, and the threaded block 13 drives the scraper 15 to move, so that the loose soil can be pushed to the side position of the bottom of the table 1, and then the second electric push rod 17 is driven to drive the reaming protective body 18 to move down, and the bottom of the reaming protective body 18 is inserted into the soil. The reaming protective body 18 can flatten the loose soil around it, and then the downward-moving drill tube 5 passes through the reaming protective body 18 and is inserted into the soil, and then on the first lifting plate During the downward movement, the third motor 24 is started to drive the first gear 25 to rotate. The rotating first gear 25 drives the second gear 26 meshing with it to rotate, and the second gear 26 drives the circular tube 23 to rotate. When the circular tube 23 rotates, it drives the drill pipe 5 to rotate. Sampling is achieved by moving the rotating drill pipe 5 downward. After the sampling is completed, the drill pipe 5 is moved up to the top position of the reaming protective body 18, and then the fifth electric push rod 28 vertically installed on the second frame 4 is started to push the second lifting plate 27 downward. The second lifting plate 27 drives the cylindrical body 29 downward. When the threaded column 42 installed at the bottom of the cylindrical body 29 is threadedly connected to the threaded tube 35, the fifth electric push rod 28 is driven to push the circular body 34 downward to compress the soil in the drill pipe 5, and finally the soil in the drill pipe 5 is pushed out.
