[0036] It should be noted here that: through the setting of the driving mechanism, the crushing plate 202 moves reciprocally up and down during the rotation process.

[0037] Please refer to Figure 2 and Figure 3 , in the illustrated rotation mechanism, it includes a U-shaped plate 401 fixedly connected to the bottom of the mixing tank 102. A rotating rod 403 is rotatably connected to the U-shaped plate 401. One end of the rotating rod 403 is connected to the stirring shaft 103 through a connecting component. A motor 402 is provided on the U-shaped plate 401, and the output end of the motor 402 is connected to the other end of the rotating rod 403;

[0040] It should be noted here that: through the setting of the connecting component, during the up and down movement of the stirring shaft 103, it can always keep rotating.

[0041] Please refer to Figure 2 and Figure 3 , in the illustrated connecting cavity 501, a reset component for resetting the stirring shaft 103 is provided. The reset component is a spring 6. One end of the spring 6 is connected to the bottom wall of the connecting cavity 501, and the other end of the spring 6 is connected to the connecting plate 503 through a limiting component;

[0042] It should be noted here that: through the setting of the reset component, when the triangular plate 302 passes over the driving rod 303, under the elastic action of the spring 6, it will push the crushing plate 202 to move away from the through hole 204.

[0045] Working principle: When mixing heavy metal soil samples, first pour the soil samples into the conical sleeve 201, and then start the motor 402 to drive the rotating rod 403 to rotate. During the rotation of the rotating rod 403, the stirring shaft 103 is driven to rotate through the connecting component, and further drive each stirring rod 104 to rotate;

[0046] And during the rotation of the stirring shaft 103, the crushing plate 202 will be driven to rotate. At the same time, during the rotation of the stirring shaft 103, each triangular plate 302 on the driving ring 301 will be driven to rotate. When the triangular plate 302 abuts against the driving rod 303, under the action of the interaction force and the guiding action of the connecting component, the driving ring 301 will be pushed to move away from the mixing tank 102, thereby further driving the crushing plate 202 to move closer to the agglomerated soil. Thus, during the process of impacting and crushing the agglomerated soil, the rotation of the grinding plate 203 is used to roll the agglomerated soil, thereby improving the effect of soil crushing. When the triangular plate 302 passes over the driving rod 303, under the elastic action of the spring 6, the crushing plate 202 will be pushed to move away from the through hole 204, so that the soil accumulated in the conical sleeve 201 flows from the gap between the crushing plate 202 and the conical sleeve 201 to the lower part of the crushing plate 202, thus realizing the automatic feeding of the soil. Therefore, during the rotation of the stirring shaft 103, the crushing plate 202 will be driven to move up and down reciprocally during rotation, thus realizing the automatic crushing and feeding of the soil. And the crushed soil will flow into the mixing tank 102 from the through hole 204 and be mixed under the rotation of each stirring rod 104, thus realizing the continuity and automation of crushing and mixing, without manual operation, thereby ensuring the uniformity of mixing of heavy metal contaminated soil while improving the convenience and efficiency of soil mixing.
