Description

Technical Field

[0001] This utility model relates to the field of soil metal content detection technology, specifically a soil metal content detection device. Background Technology

[0002] Soil is a vital component of the natural environment and a fundamental resource for agricultural production. However, with the acceleration of urbanization and industrialization, heavy metals enter the soil in large quantities through sewage irrigation, atmospheric dust deposition, and industrial waste emissions. These heavy metals cannot be decomposed by soil microorganisms and easily accumulate, causing soil heavy metal pollution. Heavy metals in the soil can enter the food chain through plant absorption and animal bioaccumulation, endangering the quality and safety of agricultural products and public health. For example, heavy metals such as lead, cadmium, and mercury can accumulate in the human body, leading to various health problems related to the nervous and immune systems. Atomic absorption spectrometry (AAS) uses a light source that emits characteristic spectral lines of specific elements. These lines are absorbed by ground-state atoms in the atomizer, and the concentration of the element in the sample is determined by detecting the intensity of the absorbed light. AAS is suitable for the quantitative analysis of various metal elements, such as copper, zinc, lead, cadmium, and chromium, and is widely used in soil heavy metal detection.

[0003] Existing soil metal content detection devices suffer from the problem that impurities such as stones in the soil affect the detection of heavy metal content, making it difficult to separate these impurities. Furthermore, the existing soil metal content detection devices suffer from the problem that the sieve frame becomes damaged after long-term use, affecting the sieving effect on the soil and making it inconvenient to disassemble and replace the sieve frame. The present invention provides a soil metal content detection device that solves the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Please see Figures 1 to 6 This utility model provides a technical solution: a soil metal content detection device, comprising a base plate 1, an adjusting frame 2, and a screen frame 3. An atomic absorption spectrometer 4 and a support plate 5 are respectively installed on the top of the base plate 1. A rectangular material drop frame 6 is installed at the end of the support plate 5. A fixing plate 7 is installed behind the rectangular material drop frame 6. A servo motor 8 is installed on the top of the fixing plate 7. A disc 9 with the same center as the output axis of the servo motor 8 is installed at the output end of the servo motor 8. A positioning slider 10 is installed on the top of the disc 9. The inner... Strip plates 11 are installed on both the front wall and the inner rear wall. Strip sliders 12 are installed on both the front and rear of the adjustment frame 2. A connecting rod 13 is installed on the rear of the adjustment frame 2. Hollow blocks 14 are installed on both sides of the adjustment frame 2. A limit spring 15 is installed on the front of the hollow block 14. A pull plate 16 is installed on one end of the limit spring 15. A limit rod 17 is installed on the side of the pull plate 16 near the limit spring 15. L-shaped positioning blocks 18 and handles 19 are installed on both sides of the screen frame 3. An atomizer 20 is installed inside the atomic absorption spectrometer 4.

[0026] Specifically, the strip slider 12 slides along the length of the strip groove, which guides the screen frame 3 and improves the stability of the screen frame 3 as it moves back and forth.

[0027] Please see Figures 2 to 5 The strip plate 11 has a strip groove inside with the front and back direction as the depth direction and the left and right direction as the length direction. The end of the strip slider 12 is located inside the strip groove, and the strip slider 12 can slide along the length direction of the strip groove.

[0028] Specifically, this design facilitates the falling of soil after screening into the rectangular feed box 6, which then slides into the interior of the atomizer 20, thus improving the stability of the soil falling.

[0029] Please see Figures 1 to 3 The rectangular feeding frame 6 is positioned higher than the atomic absorption spectrometer 4, and the bottom of the rectangular feeding frame 6 corresponds to the position of the atomizer 20.

[0030] Specifically, the positioning slider 10 slides along the length of the positioning groove, which facilitates the movement of the connecting rod 13 driven by the positioning slider 10, and facilitates the back-and-forth movement of the screen frame 3, making it convenient to screen the soil.

[0031] Please see Figures 1 to 5The top of the connecting rod 13 is provided with a positioning groove with the depth direction in the up-down direction and the length direction in the front-back direction. The end of the positioning slider 10 is located inside the positioning groove, and the positioning slider 10 can slide along the length direction of the positioning groove.

[0032] Specifically, it facilitates the placement of the screen frame 3 inside the adjusting frame 2, allows the screen frame 3 to move with the adjusting frame 2, and facilitates the back-and-forth movement of the screen frame 3 to screen the soil.

[0033] Please see Figures 1 to 5 The length and width of the screen frame 3 are both smaller than the length and width of the adjustment frame 2, and the screen frame 3 is located inside the adjustment frame 2.

[0034] Specifically, the end of the L-shaped positioning block 18 is inserted into the inside of the positioning groove to facilitate positioning of the screen frame 3. The end of the limiting rod 17 is inserted into the inside of the limiting groove to facilitate limiting the position of the L-shaped positioning block 18, thereby improving the stability of the screen frame 3 during installation and facilitating the disassembly and replacement of the screen frame 3.

[0035] Please see Figures 5 to 6 The top of the cavity block 14 is provided with a positioning groove with the vertical direction as the depth direction. The end of the L-shaped positioning block 18 is inserted into the positioning groove. The front of the L-shaped positioning block 18 is provided with a limiting groove with the front and back direction as the depth direction. The end of the limiting rod 17 away from the pull plate 16 is inserted into the limiting groove. The inner top wall of the L-shaped positioning block 18 abuts against the top of the adjusting frame 2.

[0036] In use, the soil to be tested is placed inside the screen frame 3. During soil sieving, the servo motor 8 drives the disc 9 to rotate, causing the positioning slider 10 to move in a circular motion around the center of the disc 9. The movement of the positioning slider 10 moves the connecting rod 13, which in turn moves the adjusting frame 2, the screen frame 3, and the strip slider 12. The strip slider 12 slides along the length of the strip groove, facilitating the back-and-forth movement of the screen frame 3 to sieve the soil. The soil falls into the rectangular discharge frame 6 and then slides into the atomizer 20, allowing impurities such as stone particles to be sieved out and retained inside the screen frame 3. This facilitates the removal of stone particles and other impurities, preventing them from affecting the accuracy of soil testing. The atomic absorption spectrometer 4 emits characteristic spectral lines of specific elements, which are absorbed by ground-state atoms when passing through the atomizer 20. This absorption is then detected. The intensity of the light received determines the content of the element in the sample. When replacing a damaged screen frame 3, pull the pull plate 16 to move the limit rod 17, causing the limit spring 15 to contract and the end of the limit rod 17 to leave the limit groove. Then, move the screen frame 3 upwards using the handle 19 to move the L-shaped positioning block 18 out of the positioning groove, facilitating the disassembly of the screen frame 3. Conversely, when installing a new screen frame 3, move the screen frame 3 so that the end of the L-shaped positioning block 18 inserts into the interior of the positioning groove. When the inner top wall of the L-shaped positioning block 18 abuts against the top of the adjusting frame 2, the limit groove and the limit rod 17 are aligned. Release the pull plate 16, and the elastic tension of the limit spring 15 causes the end of the limit rod 17 to insert into the interior of the limit groove, facilitating the restriction of the position of the L-shaped positioning block 18. This allows for quick disassembly and replacement of the screen frame 3, improving its practicality.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
