[0002] Soil heavy metal pollution refers to the phenomenon that due to human activities, the content of trace metal elements in the soil exceeds the background value and excessive deposition causes the content to be too high, which is collectively referred to as soil heavy metal pollution. Soil heavy metals refer to the phenomenon that due to human activities, metals are added to the soil, resulting in the heavy metals in the soil being significantly higher than the original content and causing the deterioration of the ecological environment quality.

[0003] Soil heavy metal detection is the basis for the degree of soil heavy metal pollution. Before detection, the soil needs to be dissolved. After retrieval, the Chinese invention patent with the patent publication number CN112275148A discloses a soil dissolution device based on soil heavy metal detection, and the Chinese invention patent with the patent publication number CN116429533A discloses a soil dissolution device based on soil heavy metal detection. The above-mentioned prior arts all pour the soil into the dissolution container all at once, and then use a stirring device to stir to accelerate the soil dissolution. For soils containing relatively large soil particles, a water film will form outside the soil particles during the dissolution process, making it difficult for the inside to dissolve, ultimately resulting in low soil dissolution efficiency and poor dissolution effect.

It is only for the convenience of describing the technical solution of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0017] As Figures 1 - 2 shown, the soil dissolution device based on soil heavy metal detection includes a dissolution bottle 1 with an opening at the upper end. The upper end of the dissolution bottle 1 is detachably connected with an end cover 2. A feed pipe 3 communicating with the inside of the dissolution bottle 1 is arranged on the end cover 2. A motor 12 electrically connected to an external power supply is arranged on the end cover 2. The output end of the motor 12 is fixedly connected with a worm 4. One end of the worm 4 extends into the inside of the feed pipe 3, and a grinding mechanism 5 is arranged at this end. The worm 4 is in transmission connection with a worm gear 6. The worm gear 6 is rotationally connected with the end cover 2 through a first rotating shaft 7. The lower end of the first rotating shaft 7 extends into the inside of the dissolution bottle 1, and a stirring mechanism 8 is arranged at this end.

[0018] Working principle: When dissolving soil, open the end cover 2, pour the solvent into the dissolution bottle 1, cover the end cover 2, start the motor 12, add the soil into the feed pipe 3. During the operation of the motor 12, the worm 4 is driven to rotate. The worm 4 drives the grinding mechanism 5 to grind the large soil particles into small soil particles. The small soil particles fall into the solvent. The worm 4 drives the worm gear 6 to rotate, and the worm gear 6 drives the stirring mechanism 8 to stir the small soil particles. Through the dissolution method of grinding while stirring, the dissolution efficiency of soil particles is accelerated, and the dissolution effect of soil particles is improved.

[0019] To achieve the purpose of increasing the dissolution efficiency of soil particles, preferably, the grinding mechanism 5 includes a driving gear 501, a first extrusion roller 502, a driven gear 503 and a second extrusion roller 504. The driving gear 501 and the first extrusion roller 502 are both arranged on the worm 4. The driving gear 501 meshes with the driven gear 503. The driven gear 503 is rotationally connected to the outer wall of the feed pipe 3 through a second rotating shaft. One end of the second rotating shaft extends into the interior of the feed pipe 3, and a second extrusion roller 504 is arranged at this end. During the operation of the motor 12, the worm 4 will be driven to rotate. The worm 4 drives the driving gear 501 and the first extrusion roller 502 to rotate. The driving gear 501 drives the second extrusion roller 504 to rotate through the driven gear 503, and the rotation direction of the second extrusion roller 504 is opposite to that of the first extrusion roller 502. Thus, the soil particles passing between the second extrusion roller 504 and the first extrusion roller 502 are ground. The ground small particle soil falls into the dissolution bottle 1, increasing the contact area between the soil particles and the solvent and accelerating the dissolution of the soil particles.

[0020] To achieve the purpose of completely grinding the soil, preferably, a diversion cover 11 is arranged above the first extrusion roller 502 and the second extrusion roller 504. The diversion cover 11 diverts the soil particles so that they flow along the inner wall of the diversion cover 11 to between the first extrusion roller 502 and the second extrusion roller 504, making the solid reagent be completely ground.

[0021] To achieve the purpose of improving the grinding effect, preferably, spherical protrusions that intersect with each other are arranged on the surfaces of the first extrusion roller 502 and the second extrusion roller 504, increasing the contact area between the first extrusion roller 502 and the second extrusion roller 504 and improving the grinding effect.

[0022] To achieve the purpose of further accelerating the dissolution efficiency of soil particles, preferably, the stirring mechanism 8 includes a disc 801, a stirring shaft 802 and stirring paddles 803. The disc 801 is arranged at the lower end of the first rotating shaft 7. A plurality of stirring shafts 802 are rotationally connected to the disc 801. A plurality of stirring paddles 803 are uniformly arranged on the stirring shafts 802. During the operation of the motor 12, the worm 4 will be driven to rotate. The worm 4 drives the worm gear 6 to rotate. The worm gear 6 drives the disc 801 to rotate, causing the stirring paddles 803 to stir the soil and accelerating the dissolution efficiency of the soil particles.

[0023] For the purpose of further accelerating the dissolution efficiency of soil particles, preferably, a sun gear 9 coaxial with the first rotating shaft 7 is provided on the inner top wall of the end cap 2. The upper end of the stirring shaft 802 passes through the disk 801, and a planetary gear 10 is provided at this end. The sun gear 9 meshes with the planetary gear 10. During the operation of the motor 12, the worm 4 is driven to rotate. The worm 4 drives the worm gear 6 to rotate, and the worm gear 6 drives the disk 801 to rotate. Since the sun gear 9 does not rotate, therefore, while the disk 801 rotates to drive the stirring paddle 803 to revolve around the first rotating shaft 7, it will also rotate under the action of the planetary gear 10, achieving a better stirring effect and accelerating the dissolution efficiency of soil particles.

[0024] For the purpose of facilitating cleaning, preferably, the dissolution bottle 1 is threadedly connected to the end cap 2, which facilitates the disassembly of the dissolution bottle 1 and the end cap 2 for cleaning each group to avoid the influence of residual soil on subsequent detections.

[0025] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
