[0023] 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 scope of protection of the present utility model.

[0024] Please see Figures 1-4 As shown, a drying device for soil sample testing includes a drying box 1; a drying component 2 is fixedly connected inside the drying box 1, a rubber ring 3 is fixedly connected to the outer wall of the drying box 1, a cover plate 4 is sleeved on the surface of the rubber ring 3, and an observation port is opened on the top surface of the cover plate 4, and a monitoring component 5 is fixedly connected inside the observation port.

[0025] The drying assembly 2 includes a drive motor 21 fixedly connected to the bottom surface of the drying box 1. The output end of the drive motor 21 extends into the interior of the drying box 1 and a stirring blade 22 is fixedly connected to one end. The stirring blade 22 has a cavity inside and several air outlets communicating with the cavity on its top surface. A dustproof net 23 is fixedly connected to the surface of the air outlet. The blade side of the stirring blade 22 has an inclined structure and the inclined structure is attached to the inner bottom wall of the drying box 1. An electric heating net 24 is fixedly connected inside the cavity, and a fan 25 is provided on the top surface of the electric heating net 24.

[0026] During operation, the drive motor 21 of the drying component 2 is first started, which drives the stirring blade 22 to rotate inside the drying box 1. The side of the stirring blade 22 is a sloping structure, and the bottom surface of the sloping structure directly contacts and adheres to the bottom wall of the drying box 1. During rotation, the sloping structure forms a shovel surface to scoop up the soil sample from the bottom of the drying box 1. When the soil is lifted to the top area of ​​the stirring blade 22, the fan 25 blows the airflow toward the electric heating grid 24. The heated airflow enters the internal cavity of the stirring blade 22 and is ejected through the air outlet and dustproof net 23 on its top surface. The hot airflow impacts the scooped soil, causing it to turn over and be evenly heated and dried. This physical heating process avoids the damage to the soil composition caused by vacuum water absorption.

[0027] Furthermore, the monitoring component 5 includes a ring plate 51 fixedly connected to the observation port. The surface of the ring plate 51 has a plurality of ventilation holes arranged in a ring array, and a protective net 52 is fixedly connected inside the ventilation holes. An observation window 53 is fixedly connected to the inner side wall of the ring plate 51. An equipment port is opened at the center of the top surface of the observation window 53, and an equipment box 54 is fixedly connected to the top surface of the equipment port. A display device 55 is fixedly connected to the top surface of the equipment box 54. A control board 56 is fixedly connected to the inner wall of the equipment box 54. A humidity probe 57 is sleeved inside the equipment box 54, and the detection end of the humidity probe 57 passes through the equipment port and extends into the interior of the drying box 1.

[0028] During operation, the humidity probe 57 of the monitoring component 5 extends its detection end into the drying box 1 and collects humidity data in the drying box 1 in real time. The signal collected by the humidity probe 57 is transmitted to the control board 56 fixedly connected inside the equipment box 54. After processing by the control board 56, the humidity value is displayed digitally through the display device 55 fixedly connected to the top surface of the equipment box 54. Personnel can directly observe the soil drying status through the observation window 53. The moisture generated during drying is discharged through the ventilation holes in the annular array on the surface of the ring plate 51 and the internal protective net 52. Combining the data feedback from the display device 55 and the visual confirmation through the observation window 53, the operator can adjust the speed of the drive motor 21 and the heating temperature of the electric heating net 24 in real time to achieve precise drying control.

[0029] Furthermore, the electric heating mesh 24 is fixedly connected to the inside of the cavity and the fan 25 is fixedly installed on the top surface of the electric heating mesh 24;

[0030] During operation, the electric heating mesh 24 is fixedly connected to the bottom surface of the internal cavity of the stirring blade 22, while the fan 25 is vertically fixed to the top surface of the electric heating mesh 24. When the fan 25 is started, the airflow is forced downward to the surface of the electric heating mesh 24. After being fully heated, the high-temperature hot airflow rises directionally within the cavity and is eventually evenly sprayed out through the air outlet on the top surface of the stirring blade 22 and the dustproof mesh 23. This structure, through the stacked arrangement of the fan 25 and the electric heating mesh 24, ensures that the airflow is fully heated by the electric heating mesh 24, avoiding heat loss, while significantly increasing the depth of high-pressure hot air penetration into the soil layer. The core beneficial effects are: maximizing heat energy conversion efficiency and enhancing hot air permeability, thereby significantly shortening the soil drying cycle.

[0031] Furthermore, the top surface of the stirring blade 22 is provided with several air outlets, and a dustproof net 23 is fixedly connected to the surface of each air outlet.

[0032] During operation, multiple circular air outlets are evenly distributed on the top surface of the mixing blade 22, and a stainless steel dustproof net 23 is welded and fixed to the surface of each air outlet. When the mixing blade 22 rotates and scoops up soil, the hot airflow in the cavity is sprayed out in a diffused manner from the densely distributed air outlets, and the dustproof net 23 simultaneously prevents soil particles from flowing back. This design allows hot air to cover most of the top surface of the mixing blade 22. The key beneficial effect is that the layout of multiple air outlets, combined with the protective function of the dustproof net 23, not only achieves uniform diffusion of hot air to avoid local overheating of the soil, but also completely prevents the air duct from being blocked, ensuring the long-term stable operation of the equipment.

[0033] Working principle: The drive motor 21 starts and drives the stirring blade 22 to rotate inside the drying box 1. The bottom surface of the inclined structure of the stirring blade 22 is in contact with the bottom wall of the drying box 1 to scoop up the soil. The fan 25 starts at the same time and blows the airflow to the electric heating net 24, which is also in the cavity of the stirring blade 22. The heated airflow passes through multiple air outlets at the top of the cavity and through the dustproof net 23 to spray onto the scooped soil, realizing the turning and drying. The moisture generated in this process is discharged through the air vents on the surface of the ring plate 51 of the monitoring component 5 and the protective net 52. At the same time, the humidity probe 57 collects the data in the drying box 1 in real time. After being processed by the control board 56 in the equipment box 54, the humidity value is displayed on the display device 55. The operator can visually verify the soil condition through the observation window 53 and adjust the speed of the drive motor 21 or the temperature of the electric heating net 24 accordingly to precisely control the drying process.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
