Description

Technical Field

[0001] The utility model relates to the technical field of soil pollution detection, in particular to a soil pollution detection device. Background Art

[0002] When conducting soil pollutant testing, the sampled soil needs to be mixed with a chemical solution, so that chemical preparations can be used to confirm the composition of pollutants in the soil and whether the pollutants exceed the standard.

[0003] Chinese patent announcement number: CN218330882U published a mixing device for soil pollution detection device, which includes a soil collection tube and a lifting device. The soil mixing mechanism connected to the soil collection tube connects the soil collection tube to the soil mixing mechanism through the lifting mechanism. The contaminated soil is collected and lifted by the lifting mechanism. The soil sample passes through the bridge part into the treatment tank, and then the treatment tank is manually added with drugs. Then the soil mixing mechanism operates, and the rotating rod is driven by the mixing motor to rotate, thereby driving the sample to be mixed and stirred. Mechanical mixing improves the mixing efficiency, thereby improving the overall detection efficiency.

[0004] The above-mentioned prior art only achieves the mixing of soil and medicine by simple stirring. For dry soil, there is no big problem. The soil can be broken up and mixed in the medicine solution by stirring. However, for wet soil, the viscosity of the soil increases. Through simple stirring, it is difficult to evenly mix the wet soil blocks with the medicine solution because the soil is insoluble in liquid. It takes a long time to stir to achieve fusion. Therefore, the detection effect will not be very ideal. For this reason, we propose a soil pollution detection device. Utility Model Content

The utility model crushes the soil through the crushing rod, and the soil powder falls through the sieve holes and falls into the container, and the stirrer is driven to rotate by magnetic force to stir and mix the solution and powder, so that the soil and chemical reagents are evenly and fully integrated.

[0007] Preferably, there are multiple groups of breaking rods vertically distributed outside the rotating shaft, which can strike the soil blocks more intensively and increase the crushing efficiency of the clamped soil blocks.

[0008] Preferably, evenly distributed scrapers are fixed to the outside of the bottom of the rotating shaft, and the bottom of the scrapers is attached to the inner side of the bottom of the crushing cylinder, which can turn over the soil in the crushing cylinder to achieve a better crushing effect.

[0009] Preferably, an arc-shaped groove is provided on the outer side of the top of the scraper, and the feeding point of the arc-shaped groove is attached to the inner side of the bottom of the crushing cylinder, which improves the movement trajectory of the soil in the arc-shaped groove and makes the soil turning effect better.

[0010] Preferably, the bottom end of the rotating shaft passes through the bottom of the crushing cylinder, and a slide groove is provided at the bottom end of the rotating shaft, and a slider is provided for sliding in the slide groove. A pull rod is fixed to the bottom of the slider, and the bottom of the pull rod passes through the bottom end of the rotating shaft. Evenly distributed support rods are fixed to the outside of the bottom end of the pull rod, and evenly distributed fixing columns are fixed on the support rods. Evenly distributed guide rails are fixed to the inside of the installation box, and the end of the support rod away from the pull rod is against the bottom of the guide rail. A compression spring is fixed to the bottom of the slider, and the compression spring is fixed to the inner bottom of the slide groove. The fixed column is used to intermittently hit the bottom of the crushing cylinder to avoid soil particles accumulating in the sieve holes and causing blockage, thereby ensuring the smooth passage of soil particles.

[0011] Preferably, the guide rails are spiral-shaped, and the support rod slides between the guide rails to achieve up and down vibration of the support rod and the fixed column.

[0012] Preferably, the highest point of the guide rail is located above the bottom of the crushing drum, so that the support rod can always enter the guide rail during movement.

[0013] Preferably, a sealing cover is provided on the outer side of the top of the feed port to prevent external dust from falling into the feed port and mixing with the soil sample when the device is working.

[0014] Compared with traditional technology, the beneficial effects of this utility model are:

[0015] 1. The utility model breaks the soil into granules or powders through a crushing rod. The granular or powdered soil falls into a container through the sieve holes and is mixed with chemical reagents, thereby preventing the soil from absorbing liquid and becoming sticky. Compared with directly placing the soil in the chemical reagent, the efficiency of soil pollution detection is improved.

[0016] 2. Stirring and fusing with chemical reagents in granular or powder form not only improves the fusion efficiency, but also enables the soil and chemical reagents to come into uniform and sufficient contact, thereby achieving the effect of improving detection accuracy.

[0017] 3. By arranging support rods and fixed columns on the outside of the crushing cylinder that move up and down intermittently with the rotation of the rotating shaft, the up and down movement of the fixed columns hits the bottom of the crushing cylinder, vibrates the soil in the crushing cylinder, and allows the granular or powdered soil to pass through the sieve holes quickly to avoid clogging the sieve holes. At the same time, the granular or powdered soil that falls while being crushed continues to fall into the vessel, which facilitates the full mixing of the soil and chemical reagents. It avoids the situation where the soil powder cannot fully contact the reagents in the first time when entering the vessel and mixing with the chemical reagents at one time, affecting its dispersion in the reagents, resulting in some particles being moist on the outside but still dry on the inside, forming lumps that are wet on the outside and dry on the inside.

[0027] Example:

[0028] See also Figures 1-4 A soil pollution detection device includes a base 1 and an installation box 2. The base 1 is provided with a container 3 for storing a chemical solution. The installation box 2 is arranged on the top of the base 1. A soil crushing device 4 is provided in the installation box 2. An electromagnetic base 5 is fixed in the base 1. The container 3 is fixed on the top of the electromagnetic base 5. A stirrer 6 driven by the magnetic force of the electromagnetic base 5 is placed in the container 3. The soil crushing device 4 includes a rotating shaft 7 and a crushing rod 8. A crushing cylinder 9 is fixed in the installation box 2. The rotating shaft 7 is rotatably arranged in the crushing cylinder 9. There are multiple crushing rods 8, and the multiple crushing rods 8 are all fixed on the outside of the rotating shaft 7. A motor 10 is fixed on the top of the installation box 2, and the output end of the motor 10 is fixed to the rotating shaft 7. A feed port 11 is provided on the top of the installation box 2, and a sealing cover 22 is provided on the outside of the top of the feed port 11 to prevent external dust from falling into the feed port 11 and mixing in the soil sample when the device is working. The bottom of the crushing cylinder 9 is provided with evenly distributed sieve holes 12.

[0029] The soil is crushed by the crushing rod 8, and the soil powder falls through the sieve hole 12 and falls into the container 3. The stirring rod 6 is driven by magnetic force to rotate, and the solution and the powder are stirred and mixed, so that the soil and the chemical reagent are evenly and fully integrated.

[0030] At the same time, the bottom end of the rotating shaft 7 passes through the bottom of the crushing cylinder 9, and a slide groove 15 is provided at the bottom end of the rotating shaft 7. A slider 16 is provided slidingly in the slide groove 15, and a pull rod 17 is fixed to the bottom of the slider 16. The bottom of the pull rod 17 passes through the bottom end of the rotating shaft 7, and the outside of the bottom end of the pull rod 17 is fixed with evenly distributed support rods 18. Evenly distributed fixing columns 19 are fixed on the support rods 18. Evenly distributed guide rails 20 are fixed on the inside of the installation box 2. The end of the support rod 18 away from the pull rod 17 is against the bottom of the guide rail 20, and a compression spring 21 is fixed to the bottom of the slider 16. The compression spring 21 is fixed to the inner bottom of the slide groove 15. The fixed column 19 is used to intermittently hit the bottom of the crushing cylinder 9 to avoid soil particles accumulating in the sieve hole 12 and causing blockage, thereby ensuring the smooth passage of soil particles.

[0031] It is worth noting that Figure 3 As shown, the guide rail 20 is spiral-shaped, and the highest point of the guide rail 20 is located above the bottom of the crushing drum 9, so that the support rod 18 can always enter the guide rail 20 during the movement.

[0032] During the implementation process, the soil sample is placed in the crushing cylinder 9 through the feed port 11, and the motor 10 drives the rotating shaft 7 to rotate, thereby driving the crushing rod 8 to rotate. The vertically distributed multiple groups of crushing rods 8 quickly crush the soil, and the crushed soil into powder falls into the container 3 in the base 1 through the sieve hole 12. The electromagnetic seat 5 drives the stirrer 6 to rotate, and the soil powder is stirred and fused with the chemical reagent in the container 3, thereby preventing the soil from absorbing liquid and becoming sticky. Compared with directly placing the soil in the chemical reagent, the efficiency of soil pollution detection is improved. The granular or powdered state is stirred and fused with the chemical reagent. In addition to improving the fusion efficiency, it can also make the soil and the chemical reagent evenly and fully contact, thereby achieving the effect of improving the detection accuracy.

[0033] In the process of the rotating shaft 7 driving the crushing rod 8 to rotate, the rotating shaft 7 drives the pull rod 17 to rotate together through the engagement of the pull rod 17 with the bottom end of the rotating shaft 7, thereby driving the support rod 18 fixed to the pull rod 17 to rotate. Due to the presence of the compression spring 21, the pull rod 17 is always subjected to an upward pulling force, thereby driving the support rod 18 to press against the bottom of the guide rail 20. In the process of the pull rod 17 rotating with the rotating shaft 7, the support rod 18 gradually moves to a place away from the crushing barrel 9. When the support rod 18 leaves the guide rail 20, it is fixed under the action of the compression spring 21. The column 19 moves upward together with the support rod 18 and the pull rod 17, and hits the bottom of the crushing cylinder 9, knocking out the soil in the sieve hole 12 to avoid clogging the sieve hole 12. At the same time, the particles or powdered soil that fall while being crushed continue to fall into the vessel 3, which is convenient for fully mixing the soil and chemical reagents, and avoids the situation where the soil powder cannot fully contact with the reagents at the first time when entering the vessel 3 and mixing with the chemical reagents at one time, affecting its dispersion in the reagent, resulting in some particles being moist on the outside but still dry on the inside, forming lumps that are wet on the outside and dry on the inside.

[0034] In addition, evenly distributed scrapers 13 are fixed on the outside of the bottom of the rotating shaft 7, and the bottom of the scraper 13 is attached to the inner side of the bottom of the crushing cylinder 9. The scraper 13 rotates at the bottom of the crushing cylinder 9 along with the rotating shaft 7, so that the soil in the crushing cylinder 9 can be turned over to achieve a better crushing effect. By arranging an arc groove 14 on the outside of the top of the scraper 13, the movement trajectory of the soil in the arc groove 14 can be improved, so that the turning effect of the soil is better.

[0035] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and illustrated in the embodiments. Any variations or modifications may be made to the embodiments of the present invention without departing from the principles described.
