Description

Technical Field

[0001] The present invention relates to the technical field of soil detection, and in particular to a soil detection system and method for rapid sampling. Background Art

[0002] Soil refers to the loose, fertile surface layer of land, capable of supporting plant growth. Its thickness is generally around 2 meters. Soil not only provides mechanical support for plant growth but also supplies essential nutrients such as water, fertilizer, air, and heat. Soil testing involves measuring representative values ​​of factors influencing soil environmental quality to determine environmental quality (or pollution levels) and their changing trends. Soil testing generally refers to soil environmental testing.

[0003] Existing sampling equipment generally uses a drill barrel to collect soil columns, and then the soil columns need to be pushed out of the drill barrel. Some relatively moist soil samples are inconvenient to remove, and it is not convenient for workers to directly remove soil samples at different depths in the drill barrel. At the same time, the collected soil samples generally need to go through six processes before testing: drying, sorting, grinding, screening, sorting, and bottling. This makes the overall soil sample testing process more cumbersome, time-consuming and labor-intensive, which not only increases the workload and difficulty of the staff, but also reduces the efficiency of soil testing.

[0014] The present invention also discloses a rapid sampling soil detection method, which performs sampling and detection by a rapid sampling soil detection system, comprising the following steps: S1: When taking soil samples in the area to be sampled, place the foot pedal on the ground, and the staff steps on the foot pedal with both feet to fix the support frame; S2: Then control the driving motor and the electric heating element in the shaftless spiral conveying blade to work; When the drive motor is working, its output shaft drives the input shaft of the gear box to rotate. Through the meshing transmission between the gears inside the gear box, the output speeds of the first output shaft and the second output shaft are different. When the first output shaft rotates, the driving gear at its bottom engages with the driven gear on the sleeve for transmission. The driven gear drives the lifting screw to rotate through the guide bar. When the lifting screw rotates, the sleeve threadedly connected to it drives the lifting seat to move downward. When the second output shaft rotates, it drives the shaftless spiral conveying blade to rotate at high speed, so that when the sampling tube moves downward with the lifting base and penetrates into the soil, the shaftless spiral conveying blade transports the soil upward along the sampling tube, and the electric heating element in the shaftless spiral conveying blade heats and dries the moist soil; When the driving gear rotates, the driving gear engages with the gear ring on the top of the storage seat, so that the gear ring drives the storage seat to rotate relative to the lifting seat, so that the storage seat rotates automatically during the sampling process of the sampling tube moving downward; S3: The shaftless spiral conveying blade transports the dried soil sample upward and discharges it from the guide pipe. The soil discharged from the guide pipe is sequentially placed into the discharge shells of the rotating storage seat, so that the discharge shells arranged around the storage seat can store soil at different depths in sequence. A partition is provided on one side of the discharge shell close to the upper side plate, so that the mixing chamber stores the mixed soil sample between two adjacent discharge shells, and the soil placed in the collection chamber is the soil sample to be tested that is not mixed with the soil in the two adjacent discharge shells; S4: The soil sample to be tested first falls on the upper filter screen. When the storage seat rotates relative to the lifting seat, the upper bevel gear on the first rotating rod engages with the upper bevel gear ring on the lifting seat, and the lower bevel gear on the second rotating rod engages with the lower bevel gear ring on the lifting seat; When the first rotating rod rotates, the dried and agglomerated soil sample is initially crushed by the crushing rod. Gravel and grass roots are present in the crushed soil sample. The gravel avoids the rotation of the crushing rod, and the gravel and grass roots do not hinder the normal rotation and crushing work of the crushing rod. After the soil sample is initially crushed by the crushing rod, it will automatically fall down after meeting the mesh drop requirements of the upper filter. Then the soil sample will be placed on the lower filter. The second rotating rod drives the crushing roller to crush the soil sample on the lower filter. After the crushed soil sample meets the mesh drop requirements of the lower filter, it will fall onto the material guide bottom plate. S5: After the sampling is completed, the staff controls the drive motor to reversely drive the output shaft, so that the lifting seat and the storage seat are reset and moved upward. During this period, the first crushing assembly and the second crushing assembly continue to crush the soil to be inspected; After the lifting seat and the storage seat move to the initial position, the staff can directly take out the soil to be inspected and conduct inspection by opening the plug cover at the second discharge port.

[0015] Compared with the prior art, the present invention provides a rapid sampling soil detection system and detection method, which has the following beneficial effects: 1. This rapid sampling soil testing system and method rotates the storage base relative to the lifting base when the sampling tube moves downward, allowing the soil samples collected by the sampling tube to be sequentially lowered into the various discharge shells of the storage base. This facilitates the rapid collection of soil samples at different depths during the sampling process, reduces the difficulty of sampling work for staff, and improves soil testing efficiency.

[0016] 2. This rapid sampling soil testing system and method uses a shaftless spiral conveying blade to heat and dry the conveyed sample, and cooperates with the first and second crushing components to crush the dry and agglomerated soil. During the soil sampling process, drying, screening, and grinding are performed before soil testing. This facilitates the rapid removal of soil samples for testing after sampling, thereby improving soil testing efficiency.

[0017] 3. The rapid sampling soil detection system and detection method, by setting the upper filter screen into a concave arc shape, facilitates the soil sample that falls on the upper filter screen to slide toward the concave portion, so that the first rotating rod drives the crushing rod to continuously crush the soil sample that does not meet the falling requirements of the upper filter screen mesh. The lower filter screen is set to a straight plate shape, which facilitates the second rotating rod to drive the crushing roller to further crush the soil sample, thereby ensuring the crushing effect of the soil sample.

[0018] 4. This rapid sampling soil testing system and method, by providing a partition on one side of the discharge shell near the upper side plate, allows the mixing chamber to store the mixed soil sample between two adjacent discharge shells. The soil placed in the collection chamber is the soil sample to be tested that is not mixed with the soil in the two adjacent discharge shells, thus avoiding cross contamination during the soil sampling process and improving the accuracy of subsequent soil testing results at different depths.

[0024] Specifically, when soil sampling is carried out in the area to be sampled, the foot pedal 2 is placed on the ground, and the staff steps on the foot pedal 2 with both feet to fix the support frame 1. Then the driving component is controlled to work, and the driving component controls the lifting seat 4 to move downward, thereby causing the sampling part 5 to rotate and move downward, and the storage component rotates relative to the lifting seat 4, so that the soil samples collected by the sampling component are sequentially placed in a circular shape into the storage component, which is convenient for quickly collecting soil samples of different depths during the sampling process, reducing the difficulty of the sampling work of the staff and improving the efficiency of soil detection.

[0025] Example 2: Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A rapid sampling soil detection system, based on Example 1, further comprises a drive assembly including a gear box 6 fixed to the top of the lifting base 4 via a support 401, a drive motor 601 fixed to the top of the gear box 6, an output shaft of the drive motor 601 being connected to an input shaft of the gear box 6, a first output shaft 602 being provided on both sides of the gear box 6, and a second output shaft 603 being provided in the middle of the gear box 6.

[0026] Specifically, when the driving assembly is working, the driving motor 601 is controlled to operate so that the output shaft of the driving motor 601 drives the input shaft of the gear box 6 to rotate, and the gear box 6 rotates and outputs through the first output shaft 602 and the second output shaft 603 .

[0027] Example 3: Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 11 A rapid sampling soil detection system, based on Example 2, further comprises a first output shaft 602 with a driving gear 6021 rotating on a lifting seat 4, a sleeve 301 with a driven gear 302 rotatably connected to the driving gear 6021, the driven gear 302 and the lifting screw 3 being slidably arranged, a guide bar 3021 being fixedly provided on the inner side wall of the driven gear 302, and a guide groove 303 cooperating with the guide bar 3021 being formed along its axial direction.

[0028] Specifically, when the first output shaft 602 of the gear box 6 rotates, the driving gear 6021 at its bottom engages with the driven gear 302 on the sleeve 301 for transmission, and the driven gear 302 drives the lifting screw 3 to rotate through the guide bar 3021. When the lifting screw 3 rotates, the sleeve 301 threadedly connected to it drives the lifting seat 4 to move downward, and then the lifting seat 4 synchronously drives the sampling part 5 to move downward for sampling.

[0029] Example 4: Reference Figure 4 and Figure 11A rapid sampling soil detection system, based on Example 3, further, the sampling component includes a sampling tube 7 fixedly mounted on the bottom of the gear box 6, a material guide tube 701 fixedly mounted on the sampling tube 7, and an end of the second output shaft 603 away from the gear box 6 passes through the sampling tube 7 and is connected to a shaftless spiral conveying blade 6031, which rotates in the sampling tube 7, and an electric heating element is provided in the shaftless spiral conveying blade 6031.

[0030] Specifically, when the second output shaft 603 of the gear box 6 rotates, it drives the shaftless spiral conveying blade 6031 to rotate at high speed, so that when the sampling tube 7 moves down with the lifting seat 4 and penetrates into the soil, the shaftless spiral conveying blade 6031 conveys the soil upward along the sampling tube 7, and the electric heating element in the shaftless spiral conveying blade 6031 heats and dries the moist soil, preventing the sampled soil from being moist and difficult to remove, and realizing pretreatment of the soil sample before testing during the sampling process, reducing the operation time of subsequent staff and improving the efficiency of soil testing.

[0031] Example 5: Reference Figure 1-9 A rapid sampling soil detection system, based on Example 4, further comprises a storage assembly including a storage seat 8 rotatably connected to the inner side of a lifting seat 4. A movable groove 801 is defined on the side of the storage seat 8 facing away from the lifting seat 4 and cooperates with a material guide tube 701. A sealing baffle 8011 fixedly connected to the material guide tube 701 is rotatably connected within the movable groove 801. A gear ring 802 meshing with a drive gear 6021 is fixedly provided on the top of the storage seat 8.

[0032] Furthermore, a number of discharge shells 9 are evenly arranged on the inner wall of the storage seat 8 in a circular shape, and each discharge shell 9 includes an upper side plate 901 and a lower side plate 902 arranged on both sides, a material guide connecting plate 903 for connecting the upper side plate 901 and the lower side plate 902, and a material guide bottom plate 904 for connecting the two lower side plates 902. Two adjacent discharge shells 9 share the same upper side plate 901, and the material guide connecting plate 903 and the material guide bottom plate 904 are both inclined downward.

[0033] Furthermore, partitions 905 are fixed on both sides of the discharge shell 9, and the partitions 905 are placed on the upper side of the lower side plate 902. A mixing chamber for storing mixed soil samples is formed between the upper side plate 901 and the partition 905. A collecting chamber for storing test soil samples is formed between the two partitions 905 in the discharge shell 9. A first discharge port 803 that cooperates with the mixing chamber and a second discharge port 804 that cooperates with the collecting chamber are provided on the storage seat 8. Both the first discharge port 803 and the second discharge port 804 are provided with plug covers.

[0034] Specifically, when the driving gear 6021 rotates, the driving gear 6021 engages with the gear ring 802 on the top of the storage seat 8, so that the gear ring 802 drives the storage seat 8 to rotate relative to the lifting seat 4, so that the storage seat 8 rotates automatically during the sampling process of the sampling tube 7 moving downward; The shaftless spiral conveying blade 6031 transports the dried soil sample upward and discharges it from the guide pipe 701. The soil discharged from the guide pipe 701 is sequentially placed into the respective discharge shells 9 of the rotating storage seat 8, so that the discharge shells 9 arranged circumferentially of the storage seat 8 sequentially store soil at different depths. A partition 905 is provided on one side of the discharge shell 9 close to the upper side plate 901, so that the mixing chamber can store the mixed soil sample between the two adjacent discharge shells 9. The soil placed in the collecting chamber is the soil sample to be tested that is not mixed with the soil in the two adjacent discharge shells 9. For example, the soil samples stored between the two adjacent discharge shells 9 are soils with a depth of 5-10 cm and 10-15 cm respectively, and the soil placed in the mixing chamber between the two adjacent discharge shells 9 is soil with a depth of about 10 cm. If the staff detects the soil in the mixing chambers of the two discharge shells 9, the soil may be mixed with the soil in the adjacent discharge shells 9, resulting in the same soil test results in the two discharge shells 9, while the soil stored in the middle of the collecting chambers of the two discharge shells 9 is 7 / 8 cm and 12 / 13 cm respectively, which effectively avoids cross-contamination of soil tests at different depths during soil sampling and improves the accuracy of subsequent soil test results at different depths.

[0035] Example 6: Reference Figure 4-9 A rapid sampling soil detection system, based on Example 4, further, an upper filter screen 906 and a lower filter screen 907 are fixedly provided on the inner wall of the collection chamber, the collection chamber is placed in the cavity of the upper filter screen 906 and is provided with a first crushing assembly, the collection chamber is placed in the cavity of the upper filter screen 906 and the lower filter screen 907 and is provided with a second crushing assembly, the upper filter screen 906 is set to a concave arc shape, and the lower filter screen 907 is set to a straight plate shape.

[0036] Furthermore, the first crushing assembly includes a first rotating rod 10 rotatably connected to the storage seat 8, a crushing rod 1001 is provided on the outer side of the first rotating rod 10, an upper bevel gear 1002 is fixedly provided at the end of the first rotating rod 10, and an upper bevel gear ring 402 meshing with the upper bevel gear 1002 is provided in the lifting seat 4, and the second crushing assembly includes a second rotating rod 11 rotatably connected to the storage seat 8, a crushing roller 111 is provided on the outer side of the second rotating rod 11, a lower bevel gear 112 is fixedly provided at the end of the second rotating rod 11, and a lower bevel gear ring 403 meshing with the lower bevel gear 112 is provided in the lifting seat 4.

[0037] Specifically, the soil sample to be inspected first falls on the upper filter screen 906. When the storage seat 8 rotates relative to the lifting seat 4, the upper bevel gear 1002 on the first rotating rod 10 is meshed with the upper bevel gear ring 402 on the lifting seat 4 for transmission, and the lower bevel gear 112 on the second rotating rod 11 is meshed with the lower bevel gear ring 403 on the lifting seat 4 for transmission. When the first rotating rod 10 rotates, the crushing rod 1001 is used to preliminarily crush the dried and agglomerated soil sample. There are gravel and grass roots in the crushed soil sample, and the gravel is pressed against the crushing rod 10. 01 is rotated to avoid, and gravel and grass roots do not hinder the normal rotation and crushing work of the crushing rod 1001. The upper filter screen 906 is set to a concave arc, which is convenient for the soil sample dropped on the upper filter screen 906 to slide downward into the concave part, so that the first rotating rod 10 drives the crushing rod 1001 to continuously crush the soil sample that does not meet the falling requirements of the mesh of the upper filter screen 906; It should be noted that the plate on the top of the storage seat 8 is detachable, which is convenient for the subsequent cleaning of gravel and grass roots on the upper filter screen 906; After the soil sample is initially crushed by the crushing rod 1001 and meets the mesh drop requirement of the upper filter 906, it will automatically fall down, and then the soil sample will be placed on the lower filter 907. The second rotating rod 11 drives the crushing roller 111 to crush the soil sample on the lower filter 907. After the crushed soil sample meets the mesh drop requirement of the lower filter 907, it falls onto the material guide bottom plate 904. After the sampling is completed, the staff controls the drive motor 601 to reversely drive the output shaft, so that the lifting seat 4 and the storage seat 8 are reset and moved upward. During this period, the first crushing assembly and the second crushing assembly continue to crush the soil to be tested. After the lifting seat 4 and the storage seat 8 move to the initial position, the staff can directly take out the soil to be tested and test it by opening the plug cover at the second discharge port 804; The present application heats and dries the transported sample through the shaftless spiral conveying blade 6031, and cooperates with the first crushing component and the second crushing component to crush the dry and agglomerated soil, thereby realizing the drying, screening and grinding pre-treatment of the soil before testing during the soil sampling process, making it convenient for the staff to quickly take out the soil sample for testing after the sampling is completed, thereby improving the efficiency of soil testing.

[0038] The present invention also discloses a rapid sampling soil detection method, which performs sampling and detection by a rapid sampling soil detection system, comprising the following steps: S1: When taking soil samples in the area to be sampled, the foot pedal 2 is placed on the ground, and the staff steps on the foot pedal 2 with both feet to fix the support frame 1; S2: Then control the driving motor 601 and the electric heating element in the shaftless spiral conveying blade 6031 to operate; When the drive motor 601 is working, its output shaft drives the input shaft of the gear box 6 to rotate. Through the meshing transmission between the internal gears of the gear box 6, the output speeds of the first output shaft 602 and the second output shaft 603 are different. When the first output shaft 602 rotates, the driving gear 6021 at its bottom engages with the driven gear 302 on the sleeve 301 for transmission. The driven gear 302 drives the lifting screw 3 to rotate via the guide bar 3021. When the lifting screw 3 rotates, the sleeve 301 threadedly connected to it drives the lifting base 4 downward. When the second output shaft 603 rotates, the shaftless spiral conveying blade 6031 rotates at high speed. When the sampling tube 7 moves downward along the lifting base 4 and penetrates into the soil, the shaftless spiral conveying blade 6031 conveys the soil upward along the sampling tube 7. The electric heating element in the shaftless spiral conveying blade 6031 heats and dries the moist soil. When the driving gear 6021 rotates, the driving gear 6021 engages with the gear ring 802 on the top of the storage seat 8, so that the gear ring 802 drives the storage seat 8 to rotate relative to the lifting seat 4, so that the storage seat 8 rotates automatically during the sampling tube 7 moving downward for sampling; S3: The shaftless spiral conveying blade 6031 transports the dried soil sample upward and discharges it from the guide pipe 701. The soil discharged from the guide pipe 701 is sequentially placed into the discharge shells 9 of the rotating storage seat 8, so that the discharge shells 9 arranged around the storage seat 8 sequentially store soil at different depths. A partition 905 is provided on one side of the discharge shell 9 close to the upper side plate 901, so that the mixing chamber can store the mixed soil sample between two adjacent discharge shells 9, and the soil placed in the collection chamber is the soil sample to be tested that is not mixed with the soil in the two adjacent discharge shells 9; S4: The soil sample to be tested first falls onto the upper filter screen 906. When the storage base 8 rotates relative to the lifting base 4, the upper bevel gear 1002 on the first rotating rod 10 engages with the upper bevel gear ring 402 on the lifting base 4, and the lower bevel gear 112 on the second rotating rod 11 engages with the lower bevel gear ring 403 on the lifting base 4. When the first rotating rod 10 rotates, the dried and agglomerated soil sample is initially crushed by the crushing rod 1001. Gravel and grass roots are present in the crushed soil sample. The gravel avoids the rotation of the crushing rod 1001, and the gravel and grass roots do not hinder the normal rotation and crushing work of the crushing rod 1001. After the soil sample is initially crushed by the crushing rod 1001 and meets the mesh drop requirement of the upper filter 906, it will automatically fall down, and then the soil sample will be placed on the lower filter 907. The second rotating rod 11 drives the crushing roller 111 to crush the soil sample on the lower filter 907. After the crushed soil sample meets the mesh drop requirement of the lower filter 907, it falls onto the material guide bottom plate 904. S5: After the sampling is completed, the staff controls the drive motor 601 to reversely drive the output shaft, so that the lifting seat 4 and the storage seat 8 are reset and moved upward. During this period, the first crushing assembly and the second crushing assembly continue to crush the soil to be inspected; After the lifting seat 4 and the storage seat 8 move to the initial position, the staff can directly take out the soil to be inspected and conduct inspection by opening the plug cover at the second discharge port 804.

Gravel and grass roots are present in the crushed soil sample. The gravel avoids the rotation of the crushing rod (1001). The gravel and grass roots do not hinder the normal rotation and crushing work of the crushing rod (1001). After the soil sample is initially crushed by the crushing rod (1001), it automatically falls down after meeting the mesh drop requirement of the upper filter screen (906), and then the soil sample is placed on the lower filter screen (907). The second rotating rod (11) drives the crushing roller (111) to crush the soil sample placed on the lower filter screen (907), and the crushed soil sample falls onto the material guide bottom plate (904) after meeting the mesh drop requirement of the lower filter screen (907). S5: After the sampling is completed, the staff controls the driving motor (601) to reversely drive the output shaft, so that the lifting seat (4) and the storage seat (8) are reset and moved upward, and during this period, the first crushing assembly and the second crushing assembly continue to crush the soil to be inspected; After the lifting seat (4) and the storage seat (8) are moved to the initial position, the staff can directly take out the soil to be inspected and conduct inspection by opening the plug cover at the second discharge port (804).
