Description

Technical Field

[0001] This utility model relates to the field of soil environmental quality assessment, and in particular to a testing device for soil environmental quality assessment. Background Technology

[0002] Soil environmental quality assessment refers to the investigation, analysis, and evaluation of soil environmental quality through a series of scientific methods and means, in order to determine whether the soil is polluted and the degree, scope, and potential risks of pollution, so as to provide a scientific basis for soil environmental protection, rational use of land resources, and ecological security.

[0003] Currently, soil environmental quality assessment involves testing for soil pollutants, physicochemical properties, biological characteristics, and soil aggregates. Soil aggregate structure analyzers are used to assist in soil aggregate testing. However, current soil aggregate structure analyzers consist of a main instrument, multiple testing containers, and multiple storage boxes.

[0004] However, when performing soil aggregate analysis and testing with a soil aggregate structure analyzer, raw soil samples collected outdoors need to be treated to remove impurities first. Soil samples often contain various impurities such as stones, plant debris, and roots. These impurities can interfere with the soil aggregate detection process, affecting the measurement results of parameters such as particle size distribution and structural stability, thus leading to inaccurate soil environmental quality assessments. However, with current technology, the impurity removal operation cannot be integrated with the soil aggregate structure analyzer and must be completed using separate tools such as sieving equipment and tweezers. After removing impurities using separate equipment, operators still need to manually transport the soil sample to the soil aggregate structure analyzer and add the sample to the testing container before starting the testing program.

[0005] This operating mode has many drawbacks. First, the operation process is cumbersome, requiring operators to master the operation methods of multiple devices and switch between different devices repeatedly, which consumes a lot of time and energy. Second, there is a risk of spillage and contamination during sample handling, which can easily change the original state of the sample and reduce the accuracy of the test results. Third, the superposition of multiple operation steps leads to low overall testing efficiency, making it difficult to meet the needs of large-scale and rapid testing in fields such as agricultural production planning and ecological restoration projects for soil environmental quality assessment.

[0006] Therefore, it is necessary to provide a testing device for soil environmental quality assessment to solve the above-mentioned technical problems. Utility Model Content

Remove the locking bolt 25 between the circular rotating block 24 and the support fixing frame 21, then start the drive motor 23 to drive the rotating rod 22 to rotate. When the rotating rod 22 rotates, it drives the placement tank 7 to rotate through the positioning connection assembly 9. After the placement tank 7 rotates to one side of the bottom plate 1, remove the fixing bolt 93 between the mounting block 92 and the placement tank 7. Then rotate the placement tank 7 to a position perpendicular to the ground to load the raw materials.

[0024] The fixed rod 32 and the movable sleeve 33 can be used to drive the placement tank 7 to move back and forth left and right to filter and screen the soil. The connecting piece 36 can connect the hydraulic telescopic component 35 to the main body of the analyzer 1.

[0029] The use of drive motor 92 allows for the dumping of residues after the soil inside the placement tank 7 has been treated. When dumping residues on the surface of filter screen 10 inside the placement tank 7, first remove the fixing bolt 94 between the mounting block 93 and the placement tank 7. After the fixing bolt 94 is removed, start drive motor 92 to rotate the placement tank 7. When the placement tank 7 rotates, the residues on the surface of filter screen 10 can be dumped.

[0030] A flipping device 11 is provided above the placement tank 7. The flipping device 11 includes a second motor 111, a rotating rod 112, a flipping component 113, and a mounting bracket 114. The rotating rod 112 is connected to one end of the second motor 111, the flipping component 113 is connected to the bottom of the rotating rod 112, and the mounting bracket 114 is installed between the second motor 111 and the placement tank 7.

[0031] A rectangular mounting plate 12 is connected to one side of the base plate 1.

[0032] The turning device 11 can cause soil collected outdoors to accumulate when poured onto the surface of the filter screen 10.

[0033] When operating the main body of the analyzer, first turn on the instrument power and set the relevant parameters according to the experimental requirements, such as oscillation frequency (usually 30 times / minute), amplitude (such as 4 cm or 1.5 mm) and vibration time (usually 10-30 minutes). Set the water level to ensure that the water surface just submerges the sample; If necessary, either dry sieving or wet sieving can be selected. Wet sieving requires soaking the sample in deionized water followed by shaking, while dry sieving involves direct sieving.

[0034] Operating procedure: Start the instrument and allow the sample to gradually pass through sieves with different apertures during vibration, forming agglomerates of different particle sizes; After vibration, carefully remove each screen, collect the soil aggregates left on different screens, and dry and weigh them; For the wet sieving method, the sample needs to be soaked and shaken in water before separation and weighing. Data recording and analysis: Record the mass fraction of aggregates of each particle size and calculate their mass distribution; Use Excel or other software to organize and analyze the data, and draw charts to observe the changing trends of soil aggregates under different conditions.

[0035] The working principle of the soil environmental quality assessment testing device provided by this utility model is as follows: In use, first place multiple storage buckets 5 on the placement rack 42. After placing the storage buckets 5, pour the soil collected outdoors onto the surface of the filter screen 10 inside the placement tank 7. Then, start the hydraulic telescopic component 35, which drives the movable sleeve 33 to move back and forth on the surface of the fixed rod 32 through the rectangular block 34. When the hydraulic telescopic component 35 reciprocates, it drives the connecting frame 61 to move back and forth through the rectangular block 34. When the connecting frame 61 moves back and forth, it drives the limiting rod 62 to move inside the limiting hole 63.

[0036] When the connecting frame 61 moves, the rotating device 4 drives the placement tank 7 with soil to move back and forth. At the same time, the second motor 111 is started to drive the rotating rod 112 to rotate. When the rotating rod 112 rotates, it drives the flipping part 113 to turn over the soil on the surface of the filter screen 10. The soil inside the placement tank 7 can be screened through the filter screen 10 and piled up at the bottom of the inner wall of the placement tank 7 by flipping and pushing back and forth. After the soil is screened, the valve on the discharge pipe 8 is opened, and the processed soil is added to one of the storage bins 5 through the discharge pipe 8. Once the storage bin 5 is filled with soil, the valve is stopped, and the first drive motor 41 is started to rotate the placement frame 42, thereby rotating the storage bin 5 without soil to below the discharge pipe 8. The valve is then opened again, and soil is added through the discharge pipe 8.

[0037] The storage bucket 5 with added soil is taken out from the placement rack 42 and placed in the placement container inside the analyzer body 1. Then, a solution is added to the container. When the water in the container reaches the position where the storage bucket 5 is to be added soil, the addition is stopped. Then, the analyzer body is started to pull the storage bucket 5 up and down in the container to perform the soil aggregate detection operation.

[0038] Compared with related technologies, the soil environmental quality assessment testing equipment provided by this utility model has the following beneficial effects: This utility model provides a testing device for soil environmental quality assessment. Through the coordinated operation of the pushing device 3, the rotating device 4, the connecting component 6, and the positioning connecting component 9, multiple operation steps can be completed on one device. The hydraulic telescopic component 35 in the pushing device 3 can drive the movable sleeve 33 to move on the fixed rod 32, thereby driving the rotating device 4 to move, so that the storage bucket 5 can be moved to a suitable position for post-processing addition. This reduces the sample handling process, lowers the risk of sample spillage and contamination, and effectively avoids changes in the original state of the sample. The filter screen 10 installed inside the placement tank 7 can perform preliminary impurity removal treatment on the soil sample inside the equipment to prevent impurities from interfering with subsequent testing. The turning device 11 can turn the sample in the placement tank 7 to filter and screen the sample for impurities. The first motor 41 in the rotating device 4 drives the placement rack 42 to rotate, which facilitates the replacement of the storage container 5 and the placement of samples; the positioning connection component 9 can flip the placement container 7 to transport the processed sample to the subsequent testing stage. Compared with the traditional operation mode, this operation mode greatly shortens the overall testing time and can meet the needs of convenient testing.
