Then, the metal filter bag 17 is stabilized in the dissolving cup 1 through the connecting ring 13. Then, the support sleeve 19 is placed in the groove of the connecting ring 13. At this time, the stirring shaft 18 is located in the metal filter bag. 17. Then, the positioning pin 2 is inserted into the positioning sleeve 21 through the through hole of the connecting ring 13, so that the cup lid 12 is pressed tightly onto the connecting ring 13 and the support sleeve 19. At this time, the magnetic ring 22 and the magnetic block 23 magnetically attract the iron block 24, improving the insertion stability of the positioning pin 2 and the positioning sleeve 21, thereby improving the connection stability of the cup lid 12, the connecting ring 13 and the support sleeve 19 with the dissolving cup 1. The top of the connecting ring 13 has a groove that penetrates the inner side wall of the connecting ring 13. The support sleeve 19 is slidably disposed in the groove. The stirring shaft 18 is rotatably disposed in the metal filter bag 17. The output end of the servo motor 14 penetrates the cup lid 12. The bottom of the cup lid 12 is connected to the block 3. When the cup lid 12 is fixed on the connecting ring 13 and the support sleeve 19, the block 3 is inserted into the square hole of the stirring shaft 18. At this time, the servo motor 14 drives the stirring shaft 18 to rotate through the block 3. The top of the stirring shaft 18 has a square hole, and the block 3 is inserted into the square hole. The main controller 15 and the rechargeable lithium battery 16 are fixed on the left and right sides of the top of the cup lid 12, respectively.

The rechargeable lithium battery 16 supplies power to the main controller 15 and the servo motor 14, and the main controller 15 controls the servo motor 14 to work.

[0022] The bottom of the cup lid 12 has a first annular groove, and the top of the dissolving cup 1 has a second annular groove. A set of buckles 11 are fixedly installed on the left and right sides of both the dissolving cup 1 and the cup lid 12. A first sealing ring 25 is placed in the first annular groove, and a second sealing ring 26 is placed in the second annular groove. The bottom of the first sealing ring 25 fits against the top of the connecting ring 13 and the support sleeve 19, and the top of the second sealing ring 26 fits against the bottom of the connecting ring 13. After locking the buckles 11, the cup lid 12 is fixed on the dissolving cup 1. At the same time, the cup lid 12 presses down on the connecting ring 13 to fix it between the cup lid 12 and the dissolving cup 1. The first sealing ring 25 seals the connection gap between the cup lid 12 and the connecting ring 13 and the support sleeve 19, and the second sealing ring 26 seals the connection gap between the connecting ring 13 and the dissolving cup 1.

[0023] Working principle: The positioning sleeve 21 is inserted into the insertion hole of the dissolving cup 1 to position the connecting ring 13.

Then, the dissolving liquid is poured into the dissolving cup 1, and the soil sample is poured into the metal filter bag 17. Then, the positioning post 2, which passes through the through hole of the connecting ring 13, is inserted into the positioning sleeve 21. With the magnetic attraction of the magnetic ring 22 to the iron block 24, the insertion stability of the positioning post 2 is improved, so that the cup lid 12 can press the connecting ring 13 and the support sleeve 19 downwards onto the dissolving cup 1. When the cup lid 12 is fixed on the connecting ring 13 and the support sleeve 19, the block 3 is inserted into the square hole of the stirring shaft 18. The main controller 15 and the servo motor 14 are powered by the rechargeable lithium battery 16. The servo motor 14 is controlled to work. The servo motor 14 drives the stirring shaft 18 to rotate through the block 3, so as to mix and dissolve the soil sample with the solution. After dissolution, the cup lid 12 moves upward and separates from the connecting ring 13. Then the connecting ring 13 moves upward and drives the support sleeve 19 and the metal filter bag 17 to move upward and separate from the dissolution cup 1. At this time, the dissolved soil will remain in the dissolution cup 1 through the filter holes of the metal filter bag 17, while the insoluble impurities in the soil sample will remain in the metal filter bag 17. Then the support sleeve 19 moves upward and drives the stirring shaft 18 to separate from the metal filter bag 17, so as to facilitate the cleaning of impurities in the metal filter bag 17.
