Abstract
Description
Technical Field
[0001] This utility model relates to the field of soil sampling technology, specifically to a stratified sampling device for arable land soil quality. Background Technology
[0002] In order to gain a more comprehensive and accurate understanding of the properties, structure, nutrient distribution, and pollution status of the soil, and to formulate scientific and reasonable agricultural management measures and technical solutions, relevant sampling devices are usually used to conduct stratified sampling of arable land soil for subsequent soil quality testing.
[0003] However, due to the generally simple and basic structure of existing sampling devices, when conducting stratified soil sampling, it is often necessary to rely solely on the sampling experience and intuitive judgment of the staff to insert the sampling device into the soil and take samples from different layers. This method relies on manual experience and intuitive judgment, making it difficult for staff to accurately insert the sampling device to the predetermined soil depth. This results in inaccurate soil samples that cannot truly reflect the properties of the target soil layer, and introduces instability and uncertainty into the sampling process. This increases the risk of errors during the sampling process, leading to soil sample contamination, confusion, or loss, which in turn affects subsequent analysis and research results.
[0004] Therefore, we propose a stratified sampling device for arable land soil quality to solve the above problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, this invention provides a soil quality stratification sampling device for arable land, which solves the problems mentioned in the background section.
[0006] The objective of this utility model can be achieved through the following technical solutions:
[0007] A soil quality stratification sampling device for cultivated land includes a support column, a baffle fixedly connected to the lower end of the support column, a disc rotatably connected to the outer surface of the support column, and a plurality of lifting columns slidably connected through the disc. A sampling tube is fixedly connected to the lower end of each lifting column, and the initial position of each sampling tube is located on the upper surface of the baffle.
[0008] As a further embodiment of this utility model: a fixed column is fixedly connected to the outer surface of the support column, and a first threaded hole is opened at equal intervals on the fixed column. A connecting block is fixedly connected to the upper end of each lifting column, and a bolt is threaded through the connecting block. A knob is fixedly connected to one end of each bolt, and each bolt is adapted to the first threaded hole.
[0009] As a further embodiment of this utility model: a turntable is rotatably connected to the outer surface of the support column, and a plurality of second threaded holes are opened on the outer surface of the turntable. The initial positions of the turntable and the connecting block are on the same horizontal line, and the second threaded holes are all adapted to bolts.
[0010] As a further embodiment of this utility model: symmetrical sliding columns are slidably connected through the turntable, and a ring is fixedly connected between the upper ends of the two sliding columns. The ring is sleeved on the outer surface of the support column, and a locking column is symmetrically fixedly connected to the upper end of the ring. A fixing plate is provided above the ring, and the fixing plate is fixedly connected to the outer surface of the support column. The fixing plate has locking holes equidistantly arranged in a ring, and the locking columns are all locked with the locking holes.
[0011] As a further embodiment of this utility model: a spring is fixedly connected to the lower end face of the ring, and the ends of the springs away from the ring are fixedly connected to the upper end face of the turntable.
[0012] The beneficial effects of this utility model are:
[0013] 1. Through the set lifting column, connecting block, bolts, fixing column, and first threaded hole, each sampling tube can be driven to collect soil samples from different depths for preservation. This not only ensures that each sampling tube collects soil at a specific depth, avoiding inaccurate sampling depths due to insufficient human experience, but also enables more precise acquisition of samples from the target soil layer. It reduces errors caused by sampling instability and uncertainty, ensuring the accuracy and representativeness of the samples, providing more reliable data support for subsequent soil analysis and research, and preventing erroneous conclusions due to sample contamination or confusion. Furthermore, it avoids mixing with soil from other layers, improving the precision and accuracy of sampling. This provides more accurate and comprehensive data support for subsequent soil analysis and research, facilitating a deeper understanding of soil structure, properties, and change processes. Consequently, it reduces unnecessary repeated sampling and post-processing workload, improving the efficiency of the entire sampling process.
[0014] 2. The design incorporates springs, locking posts, a fixing plate, and locking holes to limit the position of the sampling tube, preventing it from rotating automatically during sampling or transport. This not only better protects the sample during transport, reducing damage or loss due to vibration or rotation, ensuring the integrity and purity of the soil sample and providing high-quality samples for subsequent analysis and research, but also prevents deviations in sampling depth or position caused by rotation, ensuring accurate collection of soil at the target depth each time and reducing sampling errors.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0022] Example:
[0023] like Figures 1-4 As shown, a soil quality stratification sampling device for cultivated land includes a support column 1, a baffle 2 fixedly connected to the lower end of the support column 1, a disc 3 rotatably connected to the outer surface of the support column 1, and several lifting columns 4 slidably connected through the disc 3. Each lifting column 4 has a sampling tube 5 fixedly connected to its lower end, and the initial position of the sampling tube 5 is located on the upper surface of the baffle 2.
[0024] In this embodiment, as Figure 1 and Figure 2 As shown, a fixed column 6 is fixedly connected to the outer surface of the support column 1. The fixed column 6 has first threaded holes 7 equidistantly opened. The upper end of the lifting column 4 is fixedly connected to a connecting block 8. The connecting block 8 is threadedly connected to a bolt 17. A knob 9 is fixedly connected to one end of the bolt 17. The bolt 17 is adapted to the first threaded hole 7. When the driving bolt 17 is rotated and inserted into the first threaded hole 7 at different heights, the height of the lifting column 4 can be controlled, and the depth of the soil sample taken by the sampling tube 5 connected to the lower end of the lifting column 4 can be adjusted.
[0025] In this embodiment, as Figure 4 As shown, a turntable 10 is rotatably connected to the outer surface of the support column 1. Several second threaded holes 18 are opened on the outer surface of the turntable 10. The turntable 10 and the connecting block 8 are initially positioned on the same horizontal line, and the second threaded holes 18 are all adapted to the bolts 17. When the driving bolts 17 rotate and slide into the second threaded holes 18, the connection between the connecting block 8 and the turntable 10 can be maintained.
[0026] In this embodiment, as Figure 2 As shown, symmetrical sliding pins 12 are slidably connected through the turntable 10. A ring 11 is fixedly connected between the upper ends of the two sliding pins 12. The ring 11 is sleeved on the outer surface of the support column 1. A locking pin 14 is symmetrically fixedly connected to the upper end of the ring 11. A fixing plate 15 is provided above the ring 11. The fixing plate 15 is fixedly connected to the outer surface of the support column 1. The fixing plate 15 has equidistant locking holes 16 in a ring. The locking pins 14 are all locked into the locking holes 16. When the locking pins 14 are locked into the locking holes 16, the ring 11 can be limited, preventing the ring 11 from being rotated by the sliding pins 12 due to external factors.
[0027] In this embodiment, as Figure 2 As shown, a spring 13 is fixedly connected to the lower end face of the ring 11. The end of the spring 13 away from the ring 11 is fixedly connected to the upper end face of the turntable 10. When the ring 11 is subjected to force and descends, it will compress the spring 13. When the force on the ring 11 disappears, the rebound force of the spring 13 can push the ring 11 to rise automatically.
[0028] The effects achieved by this embodiment are as follows: In the prior art, when performing stratified soil sampling, it often relies solely on the sampling experience and intuitive judgment of the staff to insert the sampling device into the soil to collect samples from different layers. This method depends on manual experience and intuitive judgment, making it difficult for staff to accurately insert the sampling device to the predetermined soil depth. This results in inaccurate soil samples that cannot truly reflect the properties of the target soil layer, and introduces instability and uncertainty into the sampling process, increasing the risk of errors and leading to soil sample contamination, confusion, or loss, which in turn affects subsequent analysis and research results. Compared with the prior art, this embodiment can drive each sampling tube 5 to collect soil samples from different depths and preserve them separately. This method not only allows each sampling tube 5 to collect soil samples at a specific depth, avoiding inaccurate sampling depths due to insufficient human experience, but also enables more precise acquisition of samples from the target soil layer. It reduces errors caused by sampling instability and uncertainty, ensuring sample accuracy and representativeness, and providing more reliable data support for subsequent soil analysis and research. It also prevents erroneous conclusions due to sample contamination or confusion. Furthermore, it avoids mixing with soil from other layers, improving sampling precision and accuracy. This provides more accurate and comprehensive data support for subsequent soil analysis and research, facilitating a deeper understanding of soil structure, properties, and change processes. Ultimately, it reduces unnecessary repeated sampling and post-processing work, improving the overall efficiency of the sampling process.
[0029] The overall working process and principles involved in the above embodiments are as follows:
[0030] When the staff needs to sample the soil, they first pull down the ring 11, pushing the sliding column 12 to slide down on the turntable 10. Simultaneously, this compresses the spring 13 connecting the ring 11 and the turntable 10. As the ring 11 descends, it pulls the symmetrically connected locking column 14 on its upper surface downwards, causing the locking column 14 to slide out of the locking hole 16 on the fixed plate 15. Once the locking column 14 is completely separated from the locking hole 16, the staff can rotate the ring 11, causing the sliding column 12 to rotate the turntable 10 90° on the outer surface of the support column 1. As the turntable 10 rotates, it is threadedly connected to the bolt 17 through the second threaded hole 18 on its outer surface. This allows the bolt 17 to move the connecting block 8 synchronously, causing the lifting column 4 connected to the lower end of the connecting block 8 to rotate the disc 3 synchronously on the outer surface of the support column 1, and causing one of the sampling cylinders 5 to... After the upper surface of the baffle 2 rotates out, and one of the sampling tubes 5 rotates out, the staff can release the ring 11. Through the rebound force of the spring 13 connected between the ring 11 and the turntable 10, the ring 11 can be pushed to rise automatically, so that the locking post 14 connected to the upper end of the ring 11 can be locked into the locking hole 16 opened on the fixed plate 15. This limits the ring 11, the turntable 10 and the disc 3, preventing the sampling tube 5 from rotating automatically during sampling or transportation. Not only can the fixed sampling tube 5 better protect the sample during transportation, reducing sample damage or falling due to vibration or rotation, ensuring the integrity and purity of the soil sample, and providing high-quality samples for subsequent analysis and research, but it can also avoid the sampling depth or position deviation of the sampling tube 5 caused by rotation, ensuring that the soil at the target depth can be accurately collected every time, reducing sampling errors.
[0031] After one of the sampling cylinders 5 rotates out from the upper end face of the baffle 2, the operator can turn the knob 9 above the rotated sampling cylinder 5 to rotate the bolt 17. Through the threaded connection between the bolt 17 and the connecting block 8, the bolt 17 can rotate and slide out of the connecting block 8, simultaneously driving the bolt 17 to slide out from the second threaded hole 18 on the outer surface of the turntable 10. After the bolt 17 and the second threaded hole 18 are completely separated, the operator can press down the knob 9, causing the bolt 17 to drive the connecting block 8 to descend, thus pushing the lifting column 4 on the disc 3. The step moves downward, pushing the sampling cylinder 5 connected to the lower end of the lifting column 4 down to below the baffle 2. When the bolt 17 and the uppermost threaded hole 7 on the outer surface of the fixing column 6 are at the same horizontal line, the operator can turn the knob 9 again, causing the bolt 17 to slide on the connecting block 8 and engage with the uppermost threaded hole 7, thus limiting the height of the sampling cylinder 5. After the height of the sampling cylinder 5 is limited, the operator can insert the sampling cylinder 5 into the soil to sample the soil. After the sampling cylinder 5 has finished sampling, the operator first... The sampling cylinder 5 moves upwards, and the above operation is repeated. The new sampling cylinder 5 is rotated out from above the baffle 2, and the bolts 17 connected to the new sampling cylinder 5 are respectively inserted into the first threaded holes 7 located in the middle and lower part of the outer surface of the fixed column 6. Then, the sampling cylinder 5 is used to sample again from the sampling point. This allows for sampling of soil at different depths, and the samples are stored separately. This not only ensures that each sampling cylinder 5 collects soil at a specific depth, avoiding inaccurate sampling depth due to insufficient human experience, but also enables more precise acquisition of samples from the target soil layer. It reduces errors caused by sampling instability and uncertainty, ensuring the accuracy and representativeness of the samples, providing more reliable data support for subsequent soil analysis and research, and preventing erroneous conclusions due to sample contamination or confusion. Furthermore, it avoids mixing with soil from other layers, improving the precision and accuracy of sampling, and providing more accurate and comprehensive data support for subsequent soil analysis and research. This facilitates a deeper understanding of the soil structure, properties, and change processes, thereby reducing unnecessary repeated sampling and post-processing work, and improving the efficiency of the entire sampling work.
