Description

Technical Field

[0001] The present invention relates to the technical field of sampling devices, in particular to an agricultural soil environment monitoring sampling device. Background Art

[0002] Agricultural soils are the foundation for crop growth, and their quality directly impacts food security, ecosystem balance, and human health. However, with the acceleration of industrialization, the overuse of pesticides and fertilizers, and the increase in pollutant emissions, the agricultural soil environment faces multiple challenges. According to statistics, approximately 33% of the world's soil has degraded, primarily due to heavy metal contamination, acidification, salinization, and organic matter loss. As a major agricultural country, my country faces a particularly severe soil pollution problem. In some areas, levels of heavy metals such as cadmium and arsenic exceed standards by over 10%, posing a serious threat to agricultural product safety and human health.

[0003] In this context, soil environmental monitoring has become a core component of precision agriculture and ecological conservation. Regular sampling and analysis can assess soil nutrient distribution, pollutant concentrations, and microbial activity, providing data support for scientific fertilization and pollution remediation. However, traditional sampling methods rely on manual labor, are inefficient, and susceptible to subjective factors, making them inadequate for large-scale, high-frequency monitoring.

[0004] Traditional sampling devices mostly use manual rotation mechanisms. This method will seriously increase the workload of workers and reduce work efficiency when encountering large-scale operations. When sampling, many existing devices use spiral drill bits to break up deep soil and then transport the soil to the ground. This method easily mixes soils at different depths and cannot accurately obtain soil samples at a specified depth.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

The first motor 12 is transmission-connected to the support plate 10.

[0036] Before using this device, it is necessary to drill a hole in the ground of the target area in advance. The diameter of the hole should be large enough to fit the first outer cylinder 6, the second outer cylinder 7 and the third outer cylinder 8. It should not be too large or too small to facilitate soil sampling in the target area.

[0037] Then place the bracket 1 above the drilled hole, extend or retract the first electric telescopic rod 3, drive the bottom plate 5, the rotating connection assembly and the sampling assembly to move up and down, the rotating connection assembly is used to connect the sampling assembly and the bottom plate 5, the first outer cylinder 6 is connected to the rotating connection assembly, and the rotating connection assembly can drive the first outer cylinder 6, the second outer cylinder 7 and the third outer cylinder 8 to rotate, which is convenient for sampling at different positions.

After the sampling of a soil sample is completed, the fixing mechanism will be retracted, so that the first outer cylinder 6, the second outer cylinder 7 and the third outer cylinder 8 can rotate. Before the next soil sampling, the fixing mechanism will fix the third outer cylinder 8 again.

[0039] When sampling the original soil, the third motor 19 is started, and the third motor 19 drives the shell 15 to slide in the slide groove 14, so that the second motor 13, the rotating shaft 16 and the spiral blade 17 move toward the second sampling port 20. When the spiral blade 17 extends from the second sampling port 20 and contacts the soil, the second motor 13 is started, and the second motor 13 drives the rotating shaft 16 to rotate, and the rotating shaft 16 drives the spiral blade 17 to rotate. The rotation of the spiral blade 17 will bring the soil into the second outer cylinder 7. When the soil falls from the spiral blade 17, it will fall into the sample cup 11 below; when a soil sample is sampled, the third motor 19 drives the shell 15 to move in the opposite direction, so that the rotating shaft 16 and the spiral blade 17 are retracted into the second outer cylinder 7.

[0040] To further optimize the solution, a cleaning mechanism is provided on the second outer cylinder 7, and the cleaning mechanism includes two brushes 21, which are located on the upper and lower sides of the second sampling port 20, and two second electric telescopic rods 22 are fixedly connected to the second outer cylinder 7, which are located on the upper and lower sides of the second sampling port 20, and the second electric telescopic rods 22 are transmission connected to the brushes 21.

At this time, the spiral blade 17 will reverse and move into the second outer cylinder 7.

[0042] To further optimize the solution, two elongated holes 23 are provided on the second outer cylinder 7, and the two elongated holes 23 are located on the upper and lower sides of the second sampling port 20. The output end of the second electric telescopic rod 22 is fixedly connected to the first moving block 24, and a first connecting rod 25 is fixedly connected between the first moving block 24 and the brush 21, and the first connecting rod 25 passes through the elongated hole 23.

[0043] The second electric telescopic rod 22 extends to drive the first moving block 24 to move, and the first moving block 24 drives the first connecting rod 25 and the brush 21 to move.

[0046] According to a further optimized solution, a support rod 30 is fixedly connected to the inside of the second outer cylinder 7 , a funnel 31 is fixedly connected to the support rod 30 , and the funnel 31 is located between the spiral blade 17 and the sample cup 11 .

[0047] The soil sample dropped from the spiral blade 17 will fall into the funnel 31 , and the funnel 31 facilitates the soil to enter the sample cup 11 .

[0048] To further optimize the solution, a pillar 32 is fixedly connected to the inside of the third outer cylinder 8, the support plate 10 and the pillar 32 are rotatably connected through a first bearing, a holder 33 is fixedly connected to the support plate 10, the sample cup 11 is clamped in the holder 33, a mounting plate 34 is fixedly connected between the pillar 32 and the inner wall of the third outer cylinder 8, the first motor 12 is fixedly connected to the mounting plate 34, a first gear ring 35 is fixedly connected to the support plate 10, the first gear ring 35 is concentrically arranged with the pillar 32, a first gear 36 is fixedly connected to the output shaft of the first motor 12, and the first gear 36 is meshed with the first gear ring 35.

[0049] The first motor 12 drives the first gear 36 to rotate, and the first gear 36 drives the first gear ring 35 to rotate, thereby rotating the supporting plate 10.

[0050] A further optimized solution is provided, in which the fixing mechanism includes a plurality of third electric telescopic rods 37, a mounting base 38 being fixedly connected to the third outer tube 8, the third electric telescopic rod 37 being fixedly connected to the mounting base 38, and an insertion rod 39 being fixedly connected to the output end of the third electric telescopic rod 37, the insertion rod 39 being arranged corresponding to the first through hole, and a first guide tube 40 being fixedly connected to the first through hole.

[0051] When sampling, the device needs to be fixed, and the third electric telescopic rod 37 is extended to make the insertion rod 39 extend from the first guide tube 40 to the third outer tube 8, and finally the insertion rod 39 is inserted into the soil. When the sampling is completed, the third electric telescopic rod 37 retracts the insertion rod 39.

[0052] A further optimized solution is provided, in which the rotating connection assembly includes a top plate 41, a column 42 and a fourth motor 43. A connecting pipe 44 is fixedly connected to the bottom plate 5. The inner edge of the connecting pipe 44 is provided with a thread, and the outer edge of the column 42 is provided with a thread. The column 42 and the connecting pipe 44 are threadedly connected. The column 42 passes through the top plate 41. The column 42 and the top plate 41 are rotatably connected through a second bearing. A fourth outer cylinder 45 is fixedly connected to the top plate 41. A partition 46 is fixedly connected to the fourth outer cylinder 45. The fourth motor 43 is fixedly connected to the partition 46. A second gear 47 is fixedly connected to the column 42. A third gear 48 is fixedly connected to the output shaft of the fourth motor 43. The third gear 48 is engaged with the second gear 47.

[0053] When the first outer cylinder 6, the second outer cylinder 7, the third outer cylinder 8 and the fourth outer cylinder 45 need to rotate, the fourth motor 43 is started, the fourth motor 43 drives the third gear 48 to rotate, and the third gear 48 rotates around the second gear 47, thereby rotating the fourth outer cylinder 45. The threaded connection between the column 42 and the connecting tube 44 facilitates the disassembly of the sampling assembly as a whole, making transportation more convenient.

[0054] Further optimized solution, the first outer tube 6 is fixedly connected with a first connecting inner ring 49, and the first connecting inner ring 49 is detachably connected to the fourth outer tube 45, the second outer tube 7 is fixedly connected with a second connecting inner ring 50, and the second connecting inner ring 50 is detachably connected to the first outer tube 6, and the third outer tube 8 is fixedly connected with a third connecting inner ring 51, and the third connecting inner ring 51 is detachably connected to the second outer tube 7.

[0056] The method of using this device is to drill a hole in the ground of the target area before sampling. The diameter of the hole should be large enough to fit the first outer cylinder 6, the second outer cylinder 7 and the third outer cylinder 8. It should not be too large or too small to facilitate soil sampling in the target area.

[0057] Then, the bracket 1 is placed above the drilled hole, the column 42 and the connecting tube 44 are connected, the first electric telescopic rod 3 is extended, and the first outer tube 6, the second outer tube 7, the third outer tube 8 and the fourth outer tube 45 are extended into the drilled hole. The fixing mechanism is activated, and the third electric telescopic rod 37 is extended, so that the insertion rod 39 extends from the first guide tube 40 to the third outer tube 8, and finally the insertion rod 39 is inserted into the soil.

[0058] When multiple soil sampling is performed, the third motor 19 drives the threaded rod 26 to move. When the threaded rod 26 rotates, the second moving block 27 moves. The movement of the moving block 27 drives the second connecting rod 29 and the housing 15 to move, thereby causing the second motor 13 to move toward the second sampling port 20. When the spiral blade 17 extends from the second sampling port 20 and contacts the soil, the second motor 13 is started. The second motor 13 drives the rotating shaft 16 to rotate, and the rotating shaft 16 drives the spiral blade 17 to rotate. The rotation of the spiral blade 17 will bring the soil into the second outer cylinder 7. When the soil falls from the spiral blade 17, it falls into the funnel 31 and then enters the lower In the square sample cup 11, when a soil sample is placed in a sample cup 11, the first motor 12 drives the first gear 36 to rotate, and the first gear 36 drives the first gear ring 35 to rotate, thereby rotating the support plate 10, thereby replacing another sample cup 11 to the bottom of the spiral blade 17; when changing the sampling position, the third electric telescopic rod 37 drives the insertion rod 39 to retract, and starts the fourth motor 43, and the fourth motor 43 drives the third gear 48 to rotate, and the third gear 48 will rotate around the second gear 47, thereby rotating the first outer cylinder 6, the second outer cylinder 7, the third outer cylinder 8 and the fourth outer cylinder 45. After rotating into place, the next sampling can be carried out.

[0059] Example 2

The sampling box 54 is arranged corresponding to the first sampling port.

[0061] When sampling the original soil, the fourth electric telescopic rod 52 is extended, and the sampling box 54 extends out of the first outer tube 7 from the first sampling port. The fourth electric telescopic rod 52 continues to extend, so that the sampling box 54 is inserted into the soil. During the insertion process, the gas in the sampling box 54 will be discharged from the air vent 57, and the exhaust will cause the rubber cover 58 to open. When the fourth electric telescopic rod 52 contracts, the rubber cover 58 will be tightly attached to the air vent 57, which can prevent the soil sample in the sampling box 54 from falling out, so that the soil sample remains in the sampling box 54 until the sampling box 54 completely enters the first outer tube 7. When taking out the soil in the sampling box 54, open the rubber cover 58 to allow the gas to enter the sampling box 54, which can facilitate the removal of sudden samples.
