[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides an embodiment: Please refer to Figures 1-6A portable drying device for soil sample pretreatment includes a hot air circulation component 1 and a heating component. The hot air circulation component 1 is existing technology, and its specific model can be selected according to requirements, without limitation. The heating component includes a connecting base 5, a heating bottle body that snaps into the connecting base 5, and a sealing cap 7 that fits into the heating bottle body. A positioning groove 21 is provided in the middle of the top of the connecting base 5, and a positioning block 31 is provided in the middle of the bottom of the positioning groove 21. The positioning block 31 fits into the positioning groove 21, and the heating bottle body is snapped into the connecting base 5 through the positioning block 31 and the positioning groove 21.

[0023] An air inlet pipe 20 and a return pipe 4 are provided on one side of the positioning slot 21. A connecting pipe 8 is provided at the bottom of both the air inlet pipe 20 and the return pipe 4. A clamping tube 10 is provided at the air inlet end and the air outlet end of the hot air circulation component and at one end of the connecting pipe 8. A clamping sleeve 3 adapted to the clamping tube 10 is provided at the other end of the connecting pipe 8. Through the clamping sleeve 3 and the clamping tube 10, the heating component and the hot air circulation component 1 can be clamped together. Two adjacent heating components can be clamped together. This allows the user to carry an appropriate number of heating components as needed during the use of the equipment, improving the adaptability of the drying equipment and making it easier to carry.

[0024] The inner cavity of the clamping tube 10 is equipped with a self-sealing structure. This structure includes a positioning mesh plate 25 fixedly connected to the inner side of the clamping tube 10, and a sealing block 27 connected to the positioning mesh plate 25 via a spring 26. The other end of the sealing block 27 is adapted to the outer side of the inner cavity of the clamping tube 10, and the outer diameter of the end of the clamping tube 10 away from the positioning mesh plate 25 is smaller than the outer diameter of the other end. A push rod 12 is provided in the middle of the inner cavity of the sleeve 3. During the clamping process between the clamping tube 10 and the sleeve 3, the push rod 12 can compress the sealing block 27, causing it to move away from the side of the clamping tube 10 away from the positioning mesh plate 25, thus releasing the seal of the clamping tube 10 and facilitating gas flow within the clamping tube 10. Furthermore, there is damping between the clamping tube 10 and the sleeve 3; under this damping force, the restriction on the heating component is released, and the position of the push rod 12 remains unchanged. Figure 6 As shown, the middle part of the sealing block 27 is adapted to the outer side of the inner cavity of the tube 10. The sealing block 27 is provided with mesh holes evenly on the side near the positioning mesh plate 25. The end of the sealing block 27 away from the positioning mesh plate 25 is movably connected to the inner cavity of the tube 10.

[0025] The inlet pipe 20 and the return pipe 4 are of the same size. Both the inlet pipe 20 and the return pipe 4 have a self-sealing structure II inside. A heat exchange tube 17 is installed inside the wall of the heating bottle. An inlet channel 19 and a return channel 14 are provided on the heating bottle. The inlet pipe 20 is connected to the inlet end of the heat exchange tube 17 through the inlet channel 19, and the return pipe 4 is connected to the outlet end of the heat exchange tube 17 through the return channel 14. Push rods II 15 are provided at the bottom of the inner cavities of both the inlet channel 19 and the return channel 14. The self-sealing structure II includes a positioning mesh plate II 28 and a sealing block II 9 connected to the positioning mesh plate II 28 via a spring II 29. The sealing block II 9 is adapted to the top end of the inlet pipe 20 or the top end of the return pipe 4. Figure 6 As shown, the middle part of the sealing block 29 is adapted to the top of the air inlet pipe 20, which can seal the top of the air inlet pipe 20. The end of the sealing block 29 near the positioning mesh plate 28 is evenly provided with mesh holes, and the other end of the sealing block 29 is movably connected to the inner cavity of the air inlet pipe 20. Through the setting of the self-sealing structure 2, when the heating bottle is engaged with the connecting base 5, the push rod 25 can squeeze the sealing block 29, releasing the sealing block 29 from the air inlet pipe 20 or the return pipe 4, thereby making the inner cavity of the connecting pipe 8 and the inner cavity of the heat exchange pipe 17 in a connected state. When the hot air circulation component is working, the hot air generated enters the connecting pipe 8 connected to its outlet end. The hot air in the connecting pipe 8 then enters the heat exchange pipe 17 through the connected inlet pipe 20 and inlet channel 19. During the flow of the hot air in the heat exchange pipe 17, it heats the soil sample inside the heating bottle, achieving the drying of the soil sample. The air after heat exchange flows back to the hot air circulation unit through the return channel 14, return pipe 4, connecting pipe 8 connected to the return pipe 4, and the inlet end of the hot air circulation unit connected to the connecting pipe 8. When the heating bottle is separated from the connecting base 5, the self-sealing structure 2 seals the inlet pipe 20 or return pipe 4 under the action of the spring 29, preventing gas leakage. This allows the operator to take and put in soil samples during use, improving the practicality of the equipment.

[0026] The heating bottle includes an inner bottle body 16 and an outer bottle body 6. The inner bottle body 16 is located in the middle of the inner cavity of the outer bottle body 6. The heat exchange tube 17 is located between the inner bottle body 16 and the outer bottle body 6. A heat insulation pad is provided on the outer surface of the outer bottle body 6 to reduce the influence of the external environment on the temperature inside the heating bottle. A vent 30 is provided in the middle of the sealing cap 7, through which the gas inside the heating bottle is discharged.

[0027] In addition, a stirring rod 18 is movably connected to the inner cavity of the heating bottle. The stirring blades of the stirring rod 18 contact the inside of the heating bottle. The bottom end of the stirring rod 18 extends into the inner cavity of the positioning block 31. A driven plate 13 is movably connected to the middle of the bottom of the positioning block 31. The driven plate 13 is fixedly connected to the bottom of the stirring rod 18. A turntable 22 is movably connected to the middle of the bottom of the positioning groove 21. A servo motor 24 is installed on the connecting base 5. The turntable 22 is driven by the servo motor 24. An electromagnet 23 is installed in the middle of the turntable 22. When the electromagnet 23 is energized, the electromagnet 23 and the driven plate 13 are magnetically attracted. When the heating bottle is connected to the connecting base 5, the electromagnet 23 is magnetically attracted to the driven plate 13. When seat 5 is engaged, the driven plate 13 and electromagnet 23 are in close contact. With this configuration, during operation, energizing the electromagnet 23 connects the turntable 22 to the driven plate 13. As the servo motor 24 drives the turntable 22 to rotate, the turntable 22, through the electromagnet 23, drives the driven plate 13 to rotate. The driven plate 13 then drives the stirring rod 18 to rotate, agitating the surrounding soil sample and ensuring uniform heating. Both the inner bottle 16 and the stirring rod 18 are made of materials with good thermal conductivity, such as copper, allowing heat to be transferred to the soil sample through the stirring rod 18, further increasing the drying speed. When the user needs to remove the heating bottle, pulling it outwards overcomes the magnetic attraction between the electromagnet 23 and the driven plate 13, allowing the heating bottle to be removed. The model of the electromagnet 23 can be selected according to requirements and is not limited here.

[0028] The driven plate 13 can be made of iron. The sealing cap 7 can be made of transparent, high-temperature resistant glass, allowing users to easily observe the dryness of the soil.

[0029] This application discloses a portable drying device for soil sample pretreatment, which also includes a power supply 2, which can be a lithium battery. The power supply 2 supplies power to the electrical components in the device. All electrical components involved in this application are prior art, and those skilled in the art understand their connection methods. With the help of those skilled in the art, all electrical components in this application can be connected to the power supply 2 via wires, and a suitable controller can be selected according to the actual situation to meet the control requirements. The specific connection and control sequence are described below. The electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is well known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0030] The power supply 2 and the hot air circulation component 1 are integrated into one unit, which facilitates the carrying of the device. A conductive contact 11 is provided on one side of the card tube 10, and a conductive contact 2 that is adapted to the conductive contact 11 is provided on the inner wall of the card sleeve 3. The conductive contact 11 at one end of the connecting tube 8 and the conductive contact 2 at the other end are connected by a wire. The current at the conductive contact 11 can flow to the conductive contact 2 through the wire.

[0031] In summary: When using this portable drying device for soil sample pretreatment, the user increases the number of heating components according to the number of soil samples to be heated, puts the soil samples to be dried into the heating bottle, seals the heating bottle with the sealing cap 7, and then engages the heating bottle with the connecting base 5. After the heating bottle is engaged with the connecting base 5, the push rod 15 presses against the sealing block 9 to release the sealing block 9 from the air inlet pipe 20 or the return pipe 4. The user uses the clamping tube 10 and the clamping sleeve 3 to clamp the heating component to the hot air circulation component 1, and clamps two adjacent heating components. During the clamping process of the clamping tube 10 and the clamping sleeve 3, the push rod 12 blocks the sealing block 27, and releases the sealing block 27 from the clamping tube 10. The connecting pipe 8 is in a connected state with the air outlet or air inlet of the hot air circulation component. The inner cavities of two adjacent connecting pipes 8 on the same straight line are in a connected state. The hot air generated when the hot air circulation component 1 is working can enter the heat exchange tube 17 through the connecting pipe 8, the air inlet pipe 20, and the air inlet channel 19. The hot air heats the soil during the flow in the heat exchange tube 17, improving the soil drying efficiency. The air after heat exchange flows back to the hot air circulation component through the return channel 14, the return pipe 4, the connecting pipe 8 connected to the return pipe 4, and the air inlet of the hot air circulation component. During the drying process of the soil sample, the electromagnet 23 is energized. The energization of the electromagnet 23 causes the electromagnet 23 to be magnetically attracted to the driven plate 13. When the servo motor 24 drives the turntable 22 to rotate, the turntable 22 drives the driven plate 13 to rotate through the electromagnet 23. The driven plate 13 drives the stirring rod 18 to rotate. The stirring rod 18 agitates the soil sample and transfers heat, thereby increasing the drying speed of the soil sample. The gas generated during the drying process of the soil sample is discharged through the exhaust port 30.
