[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0017] like Figures 1-7 As shown, one embodiment of this utility model discloses a soil testing device, comprising: The detector body 1 is an existing portable XRF device, with Figure 1 Taking the perspective as an example, the detector body 1 is inverted, and the following descriptions of the orientation of the detector body 1 are all based on this. Figure 1 Main perspective; The cylinder 2 is detachably connected to the bottom of the detector body 1, located at the tail end of the detector body 1. When the cylinder 2 is detached, soil samples can be added into it through the opening. A grinding mesh 3 is connected to the bottom of the cylinder 2, and the soil sample falls onto the grinding mesh 3. A rotating rod 4 is rotatably mounted on the top surface of the grinding mesh 3, and inclined plates 5 are movably distributed around its periphery, overlapping the top of the grinding mesh 3. The bottom surface of the inclined plate 5 forms an acute angle with the grinding mesh 3, and the top surface forms an obtuse angle with the grinding mesh 3. When the rotating rod 4 rotates clockwise, the top surface of the inclined plate 5 overlaps with the grinding mesh 3. When the soil sample comes into contact with the grinding mesh 3, it slides over the top surface of the inclined plate 5, which can turn the soil sample on top of the grinding mesh 3. When the rotating rod 4 reverses at high speed, the bottom surface of the inclined plate 5 comes into contact with the soil sample. At this time, the inclined plate 5 will break up the large volume of soil sample. At the same time, the soil sample will enter the angle between the inclined plate 5 and the grinding mesh 3. With the continuous rotation of the inclined plate 5, the soil sample in the cylinder 2 can be ground into small particles with uniform particle size by the grinding mesh 3, so that the particle size of the soil sample will not easily affect the detection effect. Drive unit 6 is used to drive the rotating rod 4 to rotate; The collection box 7 is detachably connected to the detection end of the instrument body 1 and the bottom end of the cylinder 2. When the collection box 7 is installed at the bottom end of the cylinder 2, it is used to carry the small-particle soil sample after grinding. Then, it can be switched to the detection end of the instrument body 1 for detection. The drying component 8 is installed on the main body 1 of the detector and is used to dry the soil sample inside the cylinder 2. When the rotating rod 4 rotates forward and the soil sample is turned over by the inclined plate 5, the drying component 8 can be activated to effectively dry the soil sample so that the humidity of the soil sample does not easily affect the detection effect. In use, first add a soil sample into the cylinder 2, then connect it to the bottom of the detector body 1. Then, drive the rotating rod 4 to rotate clockwise via the drive unit 6. Simultaneously, drive the drying assembly 8 to operate, which can quickly dry the soil sample while the inclined plate 5 flips the soil sample on top of the grinding mesh 3. After drying is complete, as... Figure 2 As shown, the collection box 7 can be connected to the cylinder 2. At this time, when the rotating rod 4 is driven to reverse at high speed by the drive unit 6, the large volume of soil sample is broken up by the high-speed moving inclined plate 5. The broken soil sample will then enter the angle between the inclined plate 5 and the grinding mesh 3. With the continuous movement of the inclined plate 5, the soil sample can be ground into small particles with uniform particle size. The collection box 7 can receive the soil sample passing through the grinding mesh 3. Finally, the collection box 7 can be removed from the cylinder 2 and installed at the detection end of the detector body 1. The detector body 1 can then detect the soil sample after drying and grinding. It should be specifically noted that the instrument body 1 needs to be inverted during the drying and grinding operations, while the detection end of the instrument body 1 needs to face downwards when testing soil samples. Because the soil sample is dried inside the cylinder 2 and received by the collection box 7, and both the cylinder 2 and the collection box 7 are detachable, after use, the two can be removed, the soil sample that has been tested in the collection box 7 can be poured out, and the soil sample remaining in the cylinder 2 and the collection box 7 can be cleaned. This invention utilizes a drying component 8 added to the detector body 1, along with a grinding mesh 3 and an inclined plate 5 inside the cylinder 2, to dry and grind collected soil samples. This reduces the interference of soil moisture and particle size on XRF detection, improving the reliability of the detection data. Furthermore, the device proposed in this invention has the advantages of simple structure and convenient operation, making it suitable for field work environments.

[0018] like Figure 2As shown, in some embodiments, the drying assembly 8 includes a cavity 801 constructed at the tail end of the detector body 1. The cavity 801 is cylindrical, and a blade 802 is rotatably mounted inside the cavity 801. The blade 802 is rotatably mounted on the inner wall of the cavity 801 and located in the middle of the cavity 801. A motor 803 is provided to drive the blade 802 to rotate. The motor 803 is installed inside the detector body 1, and its output end passes through the cavity 801 and is connected to the blade 802. An air inlet pipe 804 and multiple air outlets 805 are constructed on the outside of the detector body 1, and are respectively connected to both ends of the cavity 801. The air inlet pipe 804 is located at the top of the cavity 801, and outside air can enter the cavity 801 through the air inlet pipe 804. Inside the cavity 801, multiple air outlets 805 are arranged in a ring at the bottom. When the motor 803 drives the blades 802 to rotate, the blades 802 can draw outside air from the air inlet pipe 804 into the cavity 801 and discharge it from the multiple air outlets 805. The air inlet pipe 804 is equipped with a heating mechanism 806, which is an electric heating wire, so as to heat the air entering the cavity 801. The multiple air outlets 805 are connected to the cylinder 2, and the heated air can enter the cylinder 2. When the soil sample at the top of the grinding mesh 3 is turned over, the hot air passes through the soil sample and is discharged from the bottom of the cylinder 2 through the grinding mesh 3. In this process, the soil sample can be dried and the moisture is discharged from the cylinder 2. It should be noted that both the motor 803 and the heating mechanism 806 are electrically connected to the battery inside the detector body 1.

[0019] like Figure 2 and Figure 6 As shown, in some embodiments, a heat-conducting cavity 9 is provided inside the cylinder 2. The heat-conducting cavity 9 is located inside the cylinder wall of the cylinder 2. Vertical tubes 10 are arranged in a ring inside the heat-conducting cavity 9. There is a gap between the bottom end of the vertical tubes 10 and the heat-conducting cavity 9. The top end of the vertical tubes 10 penetrates the top end of the cylinder 2 and is connected to the air outlet 805. After the cylinder 2 is connected to the detector body 1, the top ends of the multiple vertical tubes 10 cover the multiple air outlets 805 respectively. That is, hot air can enter the heat-conducting cavity 9 through the vertical tubes 10. Multiple heat-conducting wires 11 are distributed inside the heat-conducting cavity 9. The heat-conducting wires 11 can effectively increase the contact area between the heat-conducting cavity 9 and the hot air. The inner wall of the cylinder 2 has multiple through holes 12 arranged in a ring. These through holes 12 are interspersed with multiple vertical pipes 10 and are connected to the top of the heat-conducting cavity 9. Hot air flows from the bottom of the heat-conducting cavity 9 toward the through holes 12 through the vertical pipes 10 and enters the inner side of the cylinder 2 through the through holes 12. During the flow, the hot air will come into full contact with the heat-conducting wires 11 and transfer heat to the cylinder 2 with the help of the heat-conducting wires 11. The heat of the cylinder 2 can be transferred to the grinding mesh 3 connected to it and transferred to the soil sample through contact transfer, thereby accelerating the drying speed of the soil sample when it is turned over.

[0020] like Figure 2 and Figure 6As shown, in some embodiments, the cylinder 2 includes a heat insulation tube 201, which is made of porous ceramic material and has good heat insulation performance. An installation groove 202 is provided on its inner side, and a heat conduction tube 203 is installed in the installation groove 202. The inner side of the heat conduction tube 203 and the groove opening of the installation groove 202 are in the same curved surface. A heat conduction cavity 9 is opened on its outer side. A heat conduction wire 11 is connected to the heat conduction tube 203. The heat conduction tube 203 is made of copper-aluminum alloy and has good thermal conductivity. With this design, the temperature on the outer side of the cylinder 2 is lower during drying, and it is less likely to burn the user.

[0021] like Figure 2 , Figure 5 and Figure 6 As shown, in some embodiments, the top of the heat insulation pipe 201 is provided with a first magnet 13 distributed in a ring and staggered with the vertical pipe 10. The detector body 1 is provided with a second magnet 14. Both the first magnet 13 and the second magnet 14 are neodymium magnets and are magnetically connected to the first magnet 13. This design facilitates the connection between the cylinder 2 and the detector body 1. At the same time, under the combined action of the first magnet 13 and the second magnet 14, it is easy to align the multiple vertical pipes 10 with the multiple air outlets 805. It should be specifically noted here that, because the first magnet 13 is installed on the top of the heat insulation pipe 201, the heat on the heat conduction pipe 203 is not easily conducted to the first magnet 13. At the same time, the second magnet 14 can be connected to the detector body 1 through a rubber pad or other heat insulation material, so that when the soil sample is dried, the working temperature of the first magnet 13 and the second magnet 14 is lower than the demagnetization temperature.

[0022] like Figure 2 , Figure 4 and Figure 7 As shown, in some embodiments, the drive unit 6 includes a prism block 601 constructed at the top of the rotating rod 4. In this invention, it is a hexagonal prism with its top end higher than the top of the cylinder 2. The blade 802 rotates through the cavity 801 and has a prism groove 602 on it. The prism block 601 and the prism groove 602 are inserted into each other. The top end of the prism block 601 is in the shape of an intermittent end, which facilitates the alignment of the prism block 601 into the prism groove 602. After the cylinder 2 is connected to the detector body 1, the prism block 601 and the prism groove 602 are inserted into each other so that the rotating rod 4 can rotate forward together with the blade 802. A one-way air intake valve 603 is installed in the air intake pipe 804. When the blade 802 rotates in the reverse direction, the heating mechanism 806 is in a de-energized state. At this time, the one-way air intake valve 603 is in a closed state, that is, the rotation of the blade 802 will not drive the airflow, so as not to affect the soil sample that is broken up and ground in the cylinder 2.

[0023] like Figure 2 , Figure 4 and Figure 7As shown, in some embodiments, a first magnetic ring 15 is installed at the top of the collection box 7, a second magnetic ring 16 is installed at the bottom of the heat insulation tube 201, and a third magnetic ring 17 is installed at the detection end of the detector body 1. The first magnetic ring 15 is magnetically connected to the second magnetic ring 16 and the third magnetic ring 17. The first magnetic ring 15, the second magnetic ring 16 and the third magnetic ring 17 are all neodymium magnetic rings. This design facilitates the connection and fixation of the collection box 7, thereby facilitating the use of the device.

[0024] like Figure 1 and Figure 4 As shown, in some embodiments, the detector body 1 has a column 18, with its detection end located at the end of the column 18. A third magnetic ring 17 is located outside the column 18 and close to the connection end between the column 18 and the detector body 1. A first magnetic ring 15 is located inside the collection box 7. The collection box 7 and the column 18 are slidably engaged. With this design, when the collection box 7 is connected to the detector body 1 and the third magnetic ring 17 is magnetically connected to the first magnetic ring 15, the column 18 is inserted into the collection box 7. At this time, the distance between the detection end of the detector body 1 and the soil sample is short, which helps to improve the detection effect.

[0025] like Figure 2 , Figure 4 and Figure 6 As shown, in some embodiments, the second magnetic ring 16 is located outside the heat insulation tube 201, and the collection box 7 is slidably engaged with the cylinder 2. With this design, after the soil drying and grinding are completed, the collection box 7 can be pushed upward to slide, and the soil sample in the collection box 7 can be flattened by the grinding mesh 3. As the collection box 7 continues to move, although a small part of the soil sample will pass through the grinding mesh 3 under pressure, most of the soil sample will be compacted by the grinding mesh 3 and form a cake shape at the bottom of the collection box 7, so as to facilitate the detection end. After the soil sample is compressed, the collection box 7 and the cylinder 2 can be laid flat and separated. On the one hand, it is possible to observe whether the soil sample in the collection box 7 is loose, thereby checking the degree of compaction. On the other hand, it makes it difficult for the soil sample that has passed through the grinding mesh 3 to enter the collection box 7.

[0026] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
