Description

Technical Field

[0001] This invention relates to the field of soil testing technology, specifically to a rapid detection device for soil health indicators. Background Technology

[0002] Soil testing refers to determining the environmental quality (or pollution level) and its changing trends by measuring representative values ​​of factors affecting soil environmental quality. Soil testing is also a crucial task in modern agricultural production, providing data on soil moisture, nutrient content, pH, pollution levels, and other soil quality-related information. This data obtained from soil testing is vital for agricultural production.

[0003] Soil testing first requires taking soil samples, dissolving them in reagents, and then placing them in a testing instrument. Traditional soil sampling usually involves manual digging. This is acceptable if only the surface soil is being taken, but if it is necessary to sample soil at a certain depth below the surface, it requires a lot of manual labor and time to dig, and is inefficient. In addition, if it is necessary to sample soil at different depths at the same time, manual digging can easily mix the soil, resulting in inaccurate samples. After the soil samples are taken, they need to be shaken and mixed. Generally, when rapid testing is required in the field, manual shaking is necessary. However, manual shaking can only shake a small number of samples at a time, which is inefficient and does not achieve the purpose of rapid testing. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a rapid detection device for soil health indicators, solving the following problems: Traditional soil sampling generally involves manual excavation. While this is sufficient for sampling the surface soil, sampling soil at a certain depth requires significant manual effort and time, resulting in low efficiency. Furthermore, when sampling soil at different depths simultaneously, manual excavation easily mixes the soil, leading to inaccurate samples. After obtaining the soil samples, they need to be shaken and mixed. In field applications requiring rapid testing, manual shaking is necessary, but it can only shake a small number of samples at a time, resulting in low efficiency and failing to achieve the goal of rapid detection.

[0042] This invention provides a rapid detection device for soil health indicators, solving the problem that traditional soil sampling typically involves manual excavation. While this is sufficient for surface soil sampling, sampling soil at a certain depth requires significant manual effort and time, resulting in low efficiency. Furthermore, when sampling soil at different depths simultaneously, manual excavation easily mixes the soil, leading to inaccurate samples. After collection, soil samples need to be shaken and mixed, which is typically done manually in the field for rapid testing. However, manual shaking can only handle a small number of samples at a time, resulting in low efficiency and failing to achieve the goal of rapid detection.

[0043] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0044] like Figures 1-9 As shown, the soil health indicator rapid detection technology device of the present invention includes:

[0045] Base 11;

[0046] A bracket 13 is fixedly connected to the base 11, and a sampling box 31 is fixedly connected to one side of the bracket 13. A vibration component 4 is fixedly connected inside the sampling box 31.

[0047] The oscillation assembly 4 includes a guide tube 41, a linkage rod 42, a through hole 48, a top ball 49, a tension spring 410, a sliding disk 411, a limiting disk 412, and a circular groove 413. The guide tube 41 is fixedly connected to the side plate 211 by a fixing bracket. The linkage rod 42 passes through the guide tube 41 and is slidably connected to the guide tube 41. One end of the linkage rod 42 extends into the through hole 48 and is fixedly connected to the top ball 49. The through hole 48 is located in the fixing block 26. The sliding disk 411 is slidably connected in the through hole 48, and the limiting disk 412 is fixedly connected in the through hole 48. The sliding disk 411 is closer to the top ball 49 than the limiting disk 412. The linkage rod 42 passes through the sliding disk 411 and the limiting disk 412. The linkage rod 42 and the sliding disk 411 are fixedly connected. The linkage rod 42 and the limiting disk 412 are slidably connected. A tension spring 410 is located between the sliding disk 411 and the limiting disk 412. The tension spring 410 is nested on the linkage rod 42. One end of the tension spring 410 is fixedly connected to the sliding disk 411, and the other end of the tension spring 410 abuts against the limiting disk 412.

[0048] The top ball 49 and the circular groove 413 are engaged, and the circular groove 413 is formed in the tooth groove of the lead screw 25;

[0049] The oscillation assembly 4 further includes a push-pull rod 43, a first push plate 44, a second push plate 45, a deformation spring 46, and a rotating roller 47. The push-pull rod 43 is fixedly connected to the linkage rod 42. The push-pull rod 43 extends into the sampling box 31 and is fixedly connected to the first push plate 44. The first push plate 44 abuts against the sampling cup 36. The second push plate 45 abuts against the other side of the sampling cup 36. The deformation spring 46 is fixedly connected to the other side of the second push plate 45. One end of the deformation spring 46 is fixedly connected to the side wall of the groove 316. The rotating roller 47 is rotatably connected to the bottom of the groove 316. The sampling cup 36 is on the rotating roller 47.

[0050] In this embodiment, real-world soil testing often requires multiple tests at different locations to eliminate randomness. Therefore, the user should move the device to another designated location to take soil samples. When the lead screw 25 rotates and slides downwards, the top ball 49 slides in the groove of the lead screw 25. As the top ball 49 sinks into the circular groove 413 and then slides out of it, it drives the linkage rod 42 to slide back and forth. At this time, the tension spring 410 repeatedly extends and retracts, and the linkage rod 42 slides left and right in the guide tube 41, thus linking the... Rod 42 drives push-pull rod 43 to slide back and forth. Push-pull rod 43 drives first push plate 44 to repeatedly push sampling cup 36. Sampling cup 36 slides back and forth on rotating roller 47. Second push plate 45, supported by deformation spring 46, repeatedly pushes sampling cup 36. At this time, the reagent and soil in sampling cup 36 are constantly shaking. After a period of shaking, a soil sample that meets the testing conditions can be obtained. Then it can be directly placed in the testing instrument for testing, saving the time of manual shaking of the sample. Moreover, multiple samples can be shaken, which is highly efficient.

[0051] Specifically, the frame assembly 1 includes a base 11, wheels 12, a bracket 13, a top plate 14, and a first opening 15; the lower end of the base 11 is fixedly connected to the symmetrical wheels 12, the upper end of the base 11 is fixedly connected to the bracket 13, the upper end of the bracket 13 is fixedly connected to the top plate 14, and the top plate 14 has a rectangular first opening 15 in the middle.

[0052] In one embodiment, the user pushes the entire device to a designated position.

[0053] Specifically, the soil sampling assembly 2 includes a servo motor 21, a mobile power supply 22, a first slider 23, a first slide rail 24, a lead screw 25, a fixing block 26, a screw hole 27, and a side plate 211. The base 11 is fixedly connected to the symmetrically arranged side plates 211. One side of each side plate 211 is fixedly connected to the side wall of the first opening 15. The first slide rail 24 is provided on the side plate 211, and the first slide rail 24 is slidably connected to the first slider 23. The first slider 23 is fixedly connected to the servo motor 21. The servo motor 21 rests on the symmetrically arranged side plates 211. Between 11, the servo motor 21 and the mobile power supply 22 are electrically connected. The mobile power supply 22 is fixedly connected to the top plate 14. The output end of the servo motor 21 is fixedly connected to the lead screw 25. The lead screw 25 is screwed to the screw hole 27. The screw hole 27 is opened in the fixing block 26. The two sides of the fixing block 26 are fixedly connected to the side plate 211. The soil sampling rod 28 is detachably connected to the lower end of the lead screw 25. The lower end of the soil sampling rod 28 is fixedly connected to the drill bit 210. The soil sampling rod 28 has equidistant side holes 29 on its shaft.

[0054] In this embodiment, the user operates a controller (not shown in the figure) to control the servo motor 21 to work. The mobile power supply 22 supplies power to the servo motor 21. The output shaft of the servo motor 21 drives the lead screw 25 to rotate. Because the lead screw 25 is screwed to the screw hole 27 in the fixed block 26, the lead screw 25 will slide downward relative to the fixed block 26 when it rotates. At the same time, it drives the servo motor 21 and the first slider 23 to slide downward along the side plate 211 in the first slide rail 24. When the lead screw 25 rotates and slides downward, it drives the soil-collecting rod 28 to rotate and slide downward. The soil-collecting rod 28 drives the drill bit 210 to rotate. The drill moves downwards into the soil. Due to the interaction between the lead screw 25 and the screw hole 27, there is a downward pressure when the soil sampling rod 28 drives the drill bit 210 to drill a hole in the ground. There is no need for the traditional manual pressing of the drill rod. During the downward excavation, the soil sampling rod 28 will be filled with soil, and there will be soil overflowing in the side hole 29. The soil layer distribution inside the soil sampling rod 28 is the same as that underground. When the excavation reaches the predetermined position, the user operates the controller to control the servo motor 21 to rotate in the opposite direction. At this time, the lead screw 25 reverses and cooperates with the screw hole 27 to drive the soil sampling rod 28 to slide upwards and reset.

[0055] Specifically, the sampling assembly 3 includes a sampling box 31, a side door 32, a second opening 33, a carrier plate 35, a sampling cup 36, a second slider 37, a second slide rail 38, and a groove 316; the sampling box 31 is fixedly connected to one side of the bracket 13, the side door 32 is opened on one side of the sampling box 31, the second opening 33 is opened at one end of the sampling box 31, the carrier plate 35 is located in the second opening 33, the carrier plate 35 is located at the bottom of the sampling box 31, and the carrier plate 35... The lower end is fixedly connected to the second slider 37, which is slidably connected to the second slide rail 38. The second slide rail 38 is located at the bottom of the sampling box 31. The carrier plate 35 has a groove 316, and the sampling cup 36 is located in the groove 316. The second opening 33 has an opening 34 above it, which is located on the sampling box 31. The rotating seat 39 is fixedly connected to the inner wall of the sampling box 31 opposite to the opening 34. Sampling At this time, the soil sampling rod 28 and the opening 34 are rotatably connected, the drill bit 210 at the head of the soil sampling rod 28 abuts against the rotating seat 39, and the sampling assembly 3 also includes an inclined tube 310, a movable rod 311, a limiting block 312, a support spring 313, a third slider 314, and a third slide rail 315; the inclined tube 310 is located above the sampling cup 36, and the inclined tube 310 is fixedly connected to the movable rod 311, and the lower end faces of both ends of the movable rod 311 are fixedly connected to... The supporting spring 313 is provided, and its lower end is fixedly connected to the limiting block 312. The limiting block 312 is fixedly connected to the inner wall of the sampling box 31. The two ends of the movable rod 311 are fixedly connected to the third slider 314. The third slider 314 and the third slide rail 315 are slidably connected. The third slide rail 315 is opened on the inner wall of the sampling box 31. During sampling, the side hole 29 is directly above the inclined tube 310 and corresponds one-to-one.

[0056] In this embodiment, after soil sampling is completed, the user removes the soil sampling rod 28 from the lead screw 25, then inserts one end of the drill bit 210 of the soil sampling rod 28 into the opening 34, ensuring that the drill bit 210 and the rotating seat 39 are in contact, and then proceeds according to... Figure 2 The rotation direction shown indicates that the soil sampling rod 28 is rotated. At this time, the side hole 29 in the soil sampling rod 28 will scrape against the inclined tube 310. The soil overflowing from the side hole 29 will fall into the inclined tube 310 and then enter the sampling cup 36. The support spring 313 always exerts an upward thrust on the movable rod 311, so that the movable rod 311 exerts an upward thrust on the inclined tube 310, making the inclined tube 310 fit as closely as possible to the side hole 29 on the soil sampling rod 28. When the user rotates the soil sampling rod 28, enough soil can be scraped off. The soil obtained at this time is a soil sample from different underground depths. The user should mark the depth, etc. in the sampling cup 36 in advance.

[0057] In use, the user pushes the entire device to the designated position. The user operates the controller (not shown in the figure) to control the servo motor 21. The mobile power supply 22 supplies power to the servo motor 21. The output shaft of the servo motor 21 drives the lead screw 25 to rotate. Because the lead screw 25 is screwed to the screw hole 27 in the fixed block 26, the lead screw 25 will slide downward relative to the fixed block 26 when it rotates. At the same time, it drives the servo motor 21 and the first slider 23 to slide downward along the side plate 211 in the first slide rail 24. When the lead screw 25 rotates and slides downward, it drives the soil-collecting rod 28 to rotate and slide downward. The soil-collecting rod 28 drives the drill bit 210 to rotate and drill into the soil below. The working mechanism creates downward pressure as the soil-boring rod 28 drives the drill bit 210 to drill a hole in the ground. This eliminates the need for manual pressure on the drill rod, as is common in traditional drilling. During downward excavation, the soil-boring rod 28 is filled with soil, with soil overflowing from the side hole 29. The soil layers within the soil-boring rod 28 are identical to those underground. Once the predetermined position is reached, the user operates the controller to reverse the rotation of the servo motor 21. This causes the lead screw 25 to reverse and engage with the screw hole 27, causing the soil-boring rod 28 to slide upwards and reset. The user then removes the soil-boring rod 28 from the lead screw 25 and inserts one end of the drill bit 210 into the opening 34, ensuring that the drill bit 210 and the rotating seat 39 are in contact. Figure 2The rotation direction shown indicates that the soil sampling rod 28 is rotated. At this time, the side hole 29 in the soil sampling rod 28 will scrape against the inclined tube 310. The soil overflowing from the side hole 29 will fall into the inclined tube 310 and then into the sampling cup 36. The support spring 313 always exerts an upward thrust on the movable rod 311, thus the movable rod 311 exerts an upward thrust on the inclined tube 310, making the inclined tube 310 as close as possible to the side hole 29 on the soil sampling rod 28. When the user rotates the soil sampling rod 28, sufficient soil can be scraped off. The soil samples obtained at this time are soil samples from different underground depths. The user should mark the depth, etc., in the sampling cup 36 beforehand. The user should then move the device to another designated location for soil sampling, because in actual soil testing work, it is necessary to test the soil at different locations multiple times to eliminate randomness. When the lead screw 25 rotates again and slides downwards... During this process, the top ball 49 slides in the toothed groove of the lead screw 25. As the top ball 49 falls into the circular groove 413 and then slides out of the circular groove 413, the top ball 49 drives the linkage rod 42 to slide back and forth. At this time, the tension spring 410 repeatedly extends and retracts, and the linkage rod 42 slides left and right in the guide tube 41. The linkage rod 42 drives the push-pull rod 43 to slide back and forth. The push-pull rod 43 drives the first push plate 44 to repeatedly push the sampling cup 36. The sampling cup 36 slides back and forth on the rotating roller 47. The second push plate 45, supported by the deformation spring 46, repeatedly pushes the sampling cup 36. At this time, the reagent and soil in the sampling cup 36 are constantly shaken. After a period of shaking, a soil sample that meets the testing conditions can be obtained. Then, the user can put the previously sampled specimen into the detector for testing. Automatic shaking and mixing saves the time of manual shaking of specimens, and multiple samples can be shaken, which is highly efficient.
