Description

Technical Field

[0001] The present invention relates to the technical field of fill sampling, and specifically to a soil sampling device for soil fills. Background Art

[0002] Fill refers to the engineering operation of filling materials such as soil and stone into a designated area manually or mechanically to raise the ground, level the site, form a roadbed or the foundation of a structure, etc. In the fields of civil engineering, construction engineering, road engineering, water conservancy engineering, etc., fill is a common construction process, which plays a key role in the stability, bearing capacity and service function of the project; Before filling, it is necessary to take soil samples from the designated area, which is directly related to the stability and safety of subsequent structures such as buildings and roads. Through soil sample analysis, the physical and mechanical properties of the fill soil can be understood, such as particle composition, water content, density, bearing capacity, etc., so as to provide a scientific basis for fill design and construction, and ensure 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 engineering accidents such as uneven settlement and landslide of the fill body, bringing serious potential safety hazards and economic losses to the project; For example, when filling on soft soil foundation, if the properties and thickness of the soft soil are not understood and corresponding treatment measures are not taken, large settlement may occur after filling, affecting the normal use of the upper structure.

[0003] A Chinese patent with the publication number CN114323772B discloses a portable geographic information collection device, which relates to the technical field of geographic information collection, including a placement box and a collection mechanism. A portable mechanism is arranged on the outer wall of the placement box, and an auxiliary mechanism is arranged at the bottom of the sliding plate. In the present invention, the placement box is driven to slide by a pull rod and universal wheels at the bottom of the placement box, or two workers stand on both sides of the placement box respectively, and the device is carried by hand through the handle. The above design can not only meet the sliding on the ground, but also meet the handling of the placement box, which is convenient to carry. The rod drives the sliding plate to rotate by a certain angle, and a new drill cylinder is taken to perform soil sampling at another point through a high-frequency electric cylinder. By repeating the operation, multi-point soil sampling can be carried out, and then the sampled soil is mixed and analyzed, so that the collected soil data is more representative and the accuracy of the collected soil data is improved.

[0004] However, the above patent has the following deficiencies: The above patent samples through a high-frequency electric cylinder installed on the drill cylinder. However, in the actual practical process, the high-frequency electric cylinder will shake the soil in the drill cylinder into a loose state, and the loose soil may be mixed, resulting in the lack of prominent soil layer boundaries; During the process of taking out the soil in the drill pipe, it is laborious and time-consuming for workers, and the taken-out soil is very difficult to keep as a whole, which may lead to the failure of sampling. The existing soil sampling equipment mostly does not have the function of cleaning sundries and floating soil on the ground surface, nor can it flatten the ground around the sampling area.

A circular hole 16 is opened through the top of the tabletop 1; 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 through the top of the second frame 4, and the output end of the fifth electric push rod 28 is installed with the second lifting plate 27. The bottom of the second lifting plate 27 is vertically rotatably installed with the cylinder 29, and the bottom of the cylinder 29 is installed with a threaded column 42. The threaded column 42 movably penetrates through the circular tube 23 and extends into the drill cylinder 5, and the outer side of the threaded column 42 is threadedly engaged with an internal threaded tube 35; Specifically, when it is necessary to compress the soil sampled in the drill cylinder 5, the fifth electric push rod 28 vertically installed on the second frame 4 is started to push the second lifting plate 27 downward. The cylinder 29 is driven by the second lifting plate 27 to move downward. When the threaded column 42 installed at the bottom of the cylinder 29 penetrates through 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. Then, the fifth electric push rod 28 is continuously driven to push the circular body 34 downward to compress the soil in the drill cylinder 5, so as to ensure the integrity of the soil after it is taken out of the drill cylinder 5 and prevent the taken-out soil from breaking and affecting the sampling result. When the cylinder 29 is inserted into the drill cylinder 5, the drill cylinder 5 does not rotate, and the circular tube 23 and the cylinder 29 do not come into contact. Further, 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 engaged with a third gear 30, and the third gear 30 is sleeved and installed on the outer side of the cylinder 29; Specifically, when it is necessary to thread the threaded column 42 into the internal threaded tube 35, the threaded column 42 is driven by the downward moving cylinder 29 to move downward into the bowl-shaped guide shell 36. The shape of the bowl-shaped guide shell 36 can guide the threaded column 42 into the internal threaded tube 35. Then, the fourth motor 43 is started to drive the fourth gear 31 to rotate. The third gear 30 is driven to rotate by the rotating fourth gear 31, and the cylinder 29 is driven to rotate by the rotating third gear 30, so that the threaded column 42 can be threaded into the threaded tube 35. Then, the fourth motor 43 is stopped. Subsequently, the circular body 34 can be driven to move downward by the cylinder 29. During the rotation of the cylinder 29, the fifth electric push rod 28 is also required to push it downward. Through the cooperation of the fifth electric push rod 28 and the fourth motor 43, the threaded column 42 can be installed into the internal threaded tube 35.

[0031] Further, the punching and sampling assembly includes a circular tube body 23, a third motor 24, a first gear 25 and a second gear 26. Vertically and symmetrically installed at the inner top of the first frame 2 are sixth electric push rods 44, and the output ends of the sixth electric push rods 44 are all installed on the top of the first lifting plate 3. On both inner side walls of the first frame 2, first guide grooves 38 are vertically opened, and first guide blocks 39 are slidably installed in the first guide grooves 38. The first guide blocks 39 are all installed on the outer side of the first lifting plate 3. The circular tube body 23 vertically penetrates through the top of the first lifting plate 3 in a rotating manner, and a drill cylinder 5 is installed at the bottom of the circular tube body 23. A second gear 26 is fixedly sleeved on the outer side of the circular tube body 23, and a first gear 25 is meshed with the outer side of the second gear 26. A third motor 24 is installed on the top of the first lifting plate 3, and the output end of the third motor 24 penetrates through the first lifting plate 3 and is installed with the first gear 25; 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 meshed with it to rotate. The second gear 26 drives the circular tube body 23 to rotate. When the circular tube body 23 rotates, the drill cylinder 5 is driven to rotate. By moving downward and rotating the drill cylinder 5, sampling can be realized. The rotating drill cylinder 5 can solve the problem that vibration causes the soil to loosen and the soil is mixed.

[0032] Further, the auxiliary compaction assembly includes a guide rod 32, a spring 33 and a circular body 34. A circular body 34 is movably arranged in the drill cylinder 5, and an internally threaded tube 35 is installed at the top of the circular body 34. A bowl-shaped guide shell 36 is installed at the top of the internally threaded tube 35. A plurality of guide rods 32 are vertically installed at the top of the circular body 34, and the tops of the guide rods 32 all slidably penetrate through the top of the drill cylinder 5. Springs 33 are sleeved on the outer sides of the guide rods 32, and the springs 33 are located inside the drill cylinder 5; Specifically, during the sampling process of the drill cylinder 5, under the cooperation of the guide rod 32 and the spring 33, the circular body 34 is pushed downward 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 loosening.

[0033] Further, the cleaning assembly includes a lead screw 11, a second motor 12 and a first electric push rod 14. A lead screw 11 is rotatably installed between the rectangular plates 10, and a threaded block 13 is threadedly engaged with the outer side of the lead screw 11. A first electric push rod 14 is vertically installed at the top of the threaded block 13, and a scraper 15 is installed at the output end of the first electric push rod 14. A second motor 12 is installed on the outer side of the rectangular plate 10, and the second motor 12 is used to drive the lead screw 11 to rotate; Specifically, when it is necessary to clean the sampled ground, the first electric push rod 14 is started to push the scraper 15 downward and insert it into the floating soil layer of the ground. Then, the second motor 12 is started to drive the lead screw 11 to rotate. The rotating lead screw 11 drives the threaded block 13 to move horizontally. Through the threaded block 13, the scraper 15 is further driven to move, so that the floating soil can be pushed to one side at the bottom of the table 1. A guide tube is installed at the top of the scraper 15, and a guide post is slidably inserted into the guide tube. The tops of the guide posts are all installed at the bottom of the threaded block 13, which can improve the stability of the scraper 15 during operation.

[0034] Further, the flattening assembly includes a second electric push rod 17 and an expanded hole protection body 18. L-shaped bodies 6 are vertically installed on both sides of the circular hole 16 at the top of the table 1, and second electric push rods 17 are vertically installed at the inner tops of the L-shaped bodies 6. The output ends of the second electric push rods 17 are all installed at the top of the expanded hole protection body 18, and the expanded hole protection body 18 is located in the circular hole 16; Specifically, when it is necessary to position and flatten the cleaned ground, the second electric push rod 17 is driven to drive the expanded hole protection body 18 to move downward, and the bottom of the expanded hole protection body 18 is inserted into the soil. The top position of the expanded hole protection body 18 can flatten the surrounding soil. Then, the downward moving drill cylinder 5 penetrates through the expanded hole protection body 18 and inserts into the soil for sampling. Through the expanded hole protection body 18, the top of the ground can be positioned and restricted, so that the sampling port is in a protected state, preventing the hole from collapsing during the sampling process.

[0035] Further, the height adjustment assembly includes a fourth electric push rod 21 and a lifting column 22. Fourth electric push rods 21 are vertically installed at the inner tops of the rectangular cylinders 7, and the output ends of the fourth electric push rods 21 are provided with lifting columns 22. The tops of the lifting columns 22 are slidably inserted into the bottoms of the rectangular cylinders 7, and wheels 37 are installed at the bottoms of the lifting columns 22; Specifically, when it is necessary to move the table 1, the fourth electric push rod 21 is started to push the lifting column 22 slidably inserted into the rectangular cylinder 7 to move downward. The wheels 37 installed at the bottom of the lifting column 22 are in contact with the ground, so as to realize lifting the auger bit support leg 9, ensuring that the auger bit support leg 9 is not in contact with the ground. Then, the table 1 can be moved.

[0036] Further, the support and fixation assembly includes an auger bit support leg 9 and a first motor 8. Auger bit support legs 9 are vertically rotatably installed at the four corners of the bottom of the table 1, and a plurality of first motors 8 are installed at the top of the table 1, and the first motors 8 are used to drive the auger bit support legs 9 to rotate; Specifically, when sampling is required, the auger bit support legs 9 come into contact with the ground by shrinking the wheels 37. The table 1 can be supported by the four auger bit support legs 9. Then, the first motor 8 is started simultaneously to drive the auger bit support legs 9 to rotate. When the bottoms of the auger bit support legs 9 all rotate and drill into the soil, the table 1 can be fixed in the soil, ensuring the stability of the table 1 during operation.

[0037] Furthermore, a third electric push rod 19 is horizontally installed 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; Specifically, when it is necessary to compress the soil in the drill cylinder 5, the third electric push rod 19 is started to drive the support plate 20 to move directly above the reaming protection body 18, and then the bottom of the drill cylinder 5 is lowered to contact the top of the support plate 20, providing conditions for the circular body 34 to move downward to extrude the soil.

[0038] Furthermore, second guide grooves 40 are vertically formed on both sides inside the second frame 4, and second guide blocks 41 are slidably installed in the second guide grooves 40. The second guide blocks 41 are all installed on the outer sides of the second lifting plates 27; Specifically, during the up and down movement of the second lifting plate 27, the second guide blocks 41 installed thereon slide in the second guide grooves 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.

[0039] Working principle: When using this soil sampling device for soil filling, place the tabletop 1 in a suitable position, then lower the auger drill support leg 9 to contact the ground. Subsequently, start the first motor 8 simultaneously to drive the auger drill support leg 9 to rotate. When the bottoms of the auger drill support legs 9 all rotate and drill into the soil, then start the first electric push rod 14 to push the scraper 15 downward to insert it into the floating soil layer on the ground. Then start the second motor 12 to drive the lead screw 11 to rotate. The rotating lead screw 11 drives the threaded block 13 to move horizontally, and through the threaded block 13, the scraper 15 is driven to move, so that the floating soil can be pushed to one side at the bottom of the tabletop 1. Then drive the second electric push rod 17 to drive the hole expanding and protecting body 18 to move downward, insert the bottom of the hole expanding and protecting body 18 into the soil, and the hole expanding and protecting body 18 can flatten the floating soil around it. Then the downward moving drill cylinder 5 penetrates through the hole expanding and protecting body 18 and inserts into the soil. Subsequently, when the first lifting plate 3 moves downward, start the third motor 24 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 body 23 to rotate. When the circular tube body 23 rotates, it drives the drill cylinder 5 to rotate, and sampling is achieved through the downward moving and rotating drill cylinder 5. After sampling, move the drill cylinder 5 upward to the top position of the hole expanding and protecting body 18. Then start the fifth electric push rod 28 vertically installed on the second frame 4 to push the second lifting plate 27 downward. The second lifting plate 27 drives the cylinder 29 to move downward. When the threaded column 42 installed at the bottom of the cylinder 29 is threadedly connected to the threaded tube 35, then drive the fifth electric push rod 28 to push the circular body 34 downward to compress the soil in the drill cylinder 5, and finally push the soil in the drill cylinder 5 out.
