[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] See also Figures 1 to 4A soil detection pretreatment device includes a support platform 1, a controller 2, a steering mechanism, a steering plate 3, a grinding mechanism, a grinding cylinder 4 and a discharging mechanism. The controller 2 is fixedly connected to the support platform 1, the steering mechanism is installed on the support platform 1, a plurality of steering plates 3 are provided, and a plurality of steering plates 3 are divided into a plurality of groups of two. The plurality of steering plates 3 are all fixedly connected to the support platform 1, a plurality of grinding mechanisms are provided, and the plurality of grinding mechanisms are all installed on the support platform 1, a plurality of grinding cylinders 4 are provided, and a grinding cylinder 4 is fixedly connected between each group of steering plates 3. The plurality of grinding cylinders 4 are each equipped with a plurality of grinding beads, and the discharging mechanism is installed in the support platform 1. The grinding mechanism grinds the soil sample into powder, which is beneficial to the subsequent digestion and detection. After the grinding is completed, the steering mechanism can dump the grinding cylinder 4 to pour out the ground soil sample, and leave the grinding beads in the grinding cylinder 4. There is no need to manually separate the soil and the grinding beads, which greatly improves the grinding efficiency.

[0041] Among them, Figure 4 As shown, the steering mechanism includes a steering shaft 5 and a motor 6. There are multiple steering shafts 5, and each group of steering plates 3 is rotatably connected with a steering shaft 5. There are multiple motors 6, and one of the steering plates 3 in each group of steering plates 3 is mounted with a motor 6. The output ends of the multiple motors 6 are respectively fixedly connected to the multiple steering shafts 5. When the motor 6 is started, it drives the steering shaft 5 to rotate, so that the fine hole 14 on the grinding cylinder 4 is aligned with the discharge hole 11, and then the stirring rod 10 is rotated again to stir the mixture of the soil sample and the grinding beads, so that the ground soil sample continuously flows out of the fine hole 14, and the grinding beads with a large diameter cannot pass through the fine hole 14, so they remain in the grinding cylinder.

[0042] Secondly, if Figure 3 As shown, the grinding mechanism includes a fixed plate 7, a protective shell 8, a second motor 9 and a stirring rod 10. The fixed plate 7 is fixedly connected to the support platform 1, the protective shell 8 is rotatably connected to the fixed plate 7, the second motor 9 is fixedly connected to the bottom end of the grinding cylinder 4, and the stirring rod 10 is rotatably connected to the grinding cylinder 4. The output end of the second motor 9 is fixedly connected to the stirring rod 10. The second motor 9 drives the stirring rod 10 to rotate, thereby driving the grinding beads to continuously roll in the grinding cylinder 4 to grind the soil sample into powder.

[0043] Again, as Figure 2 As shown, the discharging mechanism includes a discharging cavity, a discharging hole 11 and a discharging hopper 12. The discharging cavity is opened in the support platform 1. There are multiple discharging holes 11. The multiple discharging holes 11 are all opened at the top of the support platform 1. The discharging hopper 12 is slidably connected in the discharging cavity. The soil sample flows out from the fine hole 14, enters the discharging cavity from the discharging hole 11, and falls on the discharging hopper 12. After the discharging hopper 12 holds a certain amount of soil sample, the discharging hopper 12 is pulled out by the handle 13, and the soil sample is taken out for use in the next step.

[0044] Among them, Figure 3As shown, a plurality of fine holes 14 are formed on the top of the grinding cylinder 4. The diameter of the fine holes 14 is smaller than the diameter of the grinding beads, so as to achieve the effect of screening out soil powder.

[0045] Finally, if Figure 1 As shown, both the protective shell 8 and the discharge hopper 12 are provided with handles 13 for facilitating opening the cover and pulling out the discharge hopper 12 .

[0046] To sum up, when the soil detection pretreatment device is in use, the soil sample is first placed in multiple grinding cylinders 4, the motor 2 9 is started, and the stirring rod 10 is rotated. The stirring rod 10 drives the soil sample and the grinding beads to rotate, and the grinding beads fully grind the soil sample. Then the motor 1 6 is started, driving the steering shaft 5 to rotate, so that the fine hole 14 on the grinding cylinder 4 faces the discharge hole 11, and the motor 2 9 is started, driving the stirring rod 10 to stir the soil sample and the grinding beads to separate the two, and soil particles with smaller diameters flow out from the fine hole 14.
