[0024] As Figures 1 to 4As shown, the connecting assembly 2 comprises a plurality of support plates 21; the plurality of support plates 21 are arranged on the outer side wall of one of the spherical shells 1; the bottom of the support plate 21 is fixedly connected with a first spring 22; the end of the first spring 22 is fixedly connected with a connecting block 23; the outer side wall of the other spherical shell 1 is fixedly connected with a plurality of clamping blocks 24; the plurality of clamping blocks 24 are arranged at the positions corresponding to the support plates 21; the clamping block 24 is arranged in an L shape; in work, when the two spherical shells 1 are tightly attached, the connecting block 23 is pulled to the position of the clamping block 24, at this time the first spring 22 is elastically stretched by the pulling force of the connecting block 23, and because the elastic force of the connecting block 23 is limited, the connecting block 23 can only move to the position of the clamping block 24; when the connecting block 23 is pulled to the end of the clamping block 24, the connecting block 23 moves the connecting block 23 to the side wall of the spherical shell 1, so that the clamping block 24 passes through the middle of the connecting block 23, and then the connecting block 23 is loosened; when the first spring 22 retracts, the connecting block 23 is clamped in the middle of the clamping block 24, thereby connecting and fixing the two spherical shells 1; through the above structure, the two spherical shells 1 can be conveniently installed and disassembled, so that a stable connection is formed between the two spherical shells 1, the problem of loosening or falling off of the two spherical shells 1 in the soil for a long time is reduced, the subsequent work of recycling and replacing the adsorbent can be effectively facilitated, and the operation efficiency of replacing and recycling the adsorbent is effectively increased.

[0025] As shown in Figures 2 to 4 , the middle of the spherical shell 1 is provided with a mounting ring 3; the mounting ring 3 is threadedly connected to the inner side wall of the adsorption hole 18; the middle of the mounting ring 3 is fixedly connected with a filter screen 31; in work, the mounting ring 3 is placed at the position of the adsorption hole 18, the mounting ring 3 is fixed in the middle of the adsorption hole 18 by rotating the mounting ring 3 through the thread, and when the spherical shell 1 is placed in the soil, the particles in the soil are blocked by the filter screen 31 from entering the inside of the spherical shell 1; through the above structure, the particles and impurities in the soil can be effectively prevented from entering the inside of the spherical shell 1 after the two spherical shells 1 are placed in the soil, the problem of clogging caused by the accumulation of soil particles in the inside of the spherical shell 1 is reduced, the direct contact between the adsorbent and the particles and impurities in the soil is reduced, thereby reducing the problem of reduced or ineffective adsorption effect caused by the clogging of the adsorbent by soil particles; because the filter screen 31 is detachable, when the filter screen 31 is clogged or severely damaged, it can be removed alone for cleaning or replacement.

[0026] As shown in Figure 2 and Figure 4As shown, the outer side wall of the spherical shell 1 is fixed with a plurality of second springs 4; a plurality of second springs 4 are equidistantly distributed; the end of the second spring 4 is fixed with a buffer plate 41; the buffer plate 41 is arc-shaped; when the two spherical shells 1 are placed inside the soil, the second spring 4 and the buffer plate 41 absorb and disperse the impact force when impacted by external force; the buffer plate 41 directly bears the friction and collision in the soil; the second spring 4 and the buffer plate 41 have good elasticity and buffering performance through the above structure, which can absorb the impact force of the two spherical shells 1 inside the soil, reduce the mechanical damage of the two spherical shells 1, maintain the stability of the spherical shell 1 in the soil, and adapt to complex geological conditions and different types of soil environment.

[0027] As shown in Figure 1 and Figure 2 , the outer side wall of the spherical shell 1 is fixed with a degradation film 5; the degradation film 5 is arranged outside a plurality of buffer plates 41; when the two spherical shells 1 are not in use, the degradation film 5 blocks the leakage of the internal adsorbent to the outside, and the degradation film 5 acts as a barrier, while the heavy metals in the soil solution are adsorbed by the internal adsorbent through the film layer; over time, the degradation film 5 gradually decomposes; the above structure can protect the spherical shell 1 from interference inside the soil, keep the surface of the spherical shell 1 clean, effectively reduce the surface wear of the spherical shell 1 after being placed in the soil, and reduce pollution to the soil environment through natural decomposition of the degradation film 5, and promote the activity of soil microorganisms, thereby improving soil fertility and soil structure.

[0028] As shown in Figure 1 , one of the spherical shells 1 is fixed with a magnetic rod 6 in the middle; the magnetic rod 6 is fixed to the outer side wall of the spherical shell 1; when the two spherical shells 1 are placed inside the soil, the magnetic rod 6 enters the soil at the same time; after a period of use, the spherical shell 1 is separated from the soil by an external magnetic field; the above structure can effectively reduce the cumbersome operation and time consumption of searching and digging, facilitate the deployment and recovery of the spherical shell 1 in the soil, and thus quickly replace and recycle the adsorbent.

[0029] As shown in Figures 1 to 3 , the elastic cloth 7 is fixed in the middle of the support plate 21; the end of the elastic cloth 7 is fixed in the middle of the connecting block 23; the elastic cloth 7 is arranged outside the first spring 22; when the two spherical shells 1 are placed inside the soil, the elastic cloth 7 isolates the first spring 22 from the soil particles, which can effectively reduce the long-term adhesion of soil to the surface of the first spring 22, reduce the accumulation of soil particles on the surface of the first spring 22, and reduce the problem of damage or jamming of the first spring 22 when the spherical shell 1 is taken out of the soil for replacement, making it difficult to open the two spherical shells 1.

[0030] When working, two different types of adsorbents are placed inside the two spherical shells 1, and the fixed plates 16 on both sides of the baffle 14 are fixed in position with the fixed rods 13. By pinching the two fixed plates 16 and pressing them towards the middle, the fixed plates 16 are elastically bent, and at the same time the baffle 14 is pushed into the interior of the spherical shell 1. When the fixed holes 17 coincide with the positions of the fixed rods 13, the fixed plates 16 are elastically reset, and the fixed rods 13 pass through the fixed holes 17 of the fixed plates 16, so that the fixed plates 16 are fixed inside the spherical shell 1. After the adsorbents are fixed inside the spherical shell 1 by the fixed plates 16, the two spherical shells 1 are attached, and the clamping rods 11 correspond to the positions of the clamping grooves 12. At this time, the clamping rods 11 are inserted into the corresponding clamping grooves 12, and the two spherical shells 1 are tightly attached to form a sphere. The two spherical shells 1 are connected by the connecting assembly 2, and then placed in the soil. The adsorbents inside the spherical shell 1 adsorb heavy metal ions in the soil through the multiple adsorption holes 18. When the two spherical shells 1 are tightly attached, the connecting block 23 is pulled towards the position of the clamping block 24. At this time, the first spring 22 is elastically stretched by the pulling force of the connecting block 23. Because the elastic force of the connecting block 23 is limited, the connecting block 23 can only move to the position of the clamping block 24. When the connecting block 23 is pulled to the end of the clamping block 24, the connecting block 23 moves the connecting block 23 to the side wall of the spherical shell 1, so that the clamping block 24 passes through the middle of the connecting block 23, and then the connecting block 23 is released. When the first spring 22 retracts, the connecting block 23 is clamped in the middle of the clamping block 24, thereby connecting and fixing the two spherical shells 1. The mounting ring 3 is placed at the position of the adsorption hole 18, and the mounting ring 3 is fixed in the middle of the adsorption hole 18 by rotating the mounting ring 3 through the threads. When the spherical shell 1 is placed in the soil, the particles in the soil are blocked from entering the interior of the spherical shell 1 by the filter screen 31. When the two spherical shells 1 are placed in the soil and subjected to external impact, the second spring 4 and the buffer plate 41 absorb and disperse these impact forces. The buffer plate 41 directly bears the friction and collision in the soil. When the two spherical shells 1 are not in use, the internal adsorbents are prevented from leaking to the outside by the degradation film 5, which also serves as a barrier. At the same time, the heavy metals in the soil solution are adsorbed by the internal adsorbents through the film layer. Over time, the degradation film 5 gradually decomposes. After the two spherical shells 1 are placed in the soil, the magnetic rod 6 simultaneously enters the interior of the soil. After a period of use, the spherical shell 1 is separated from the soil by an external magnetic field. After the two spherical shells 1 are placed in the soil, the first spring 22 is isolated from the soil particles by the elastic cloth 7.
