Description

Technical Field

[0001] This utility model relates to the field of soil testing, and in particular to a soil quick-drying device for soil testing. Background Technology

[0002] In the field of soil testing and analysis, such as the detection of soil nutrients, heavy metal content, and pollutants, it is usually necessary to dry the collected soil samples to remove moisture, facilitating subsequent grinding, sieving, and accurate analysis. Soil samples with excessive moisture content are prone to clumping, microbial growth, and interference with the accuracy of testing instruments. Therefore, soil drying is a crucial step in pretreatment before testing.

[0003] Currently, common methods for drying soil samples include natural air drying and oven drying. Natural air drying involves spreading the soil sample in a well-ventilated indoor area to air dry naturally. While this method is simple and low-cost, it is extremely time-consuming, typically requiring several days or even longer, severely limiting testing efficiency and failing to meet the timeliness requirements of modern testing work. Oven drying, on the other hand, mainly utilizes equipment such as electrically heated drying ovens to accelerate moisture evaporation through heating. Although this method can significantly shorten drying time, the high temperatures (usually around 105℃) may lead to the loss of volatile components in the soil (such as certain organic matter and mercury) or cause changes in certain chemical properties, thus affecting the reliability and accuracy of the test results.

[0004] In addition, both natural air drying and oven drying methods have problems such as inconvenience, large space occupation, or high energy consumption when processing small numbers of batches of soil samples. In particular, for scenarios that require rapid acquisition of preliminary moisture content data or rapid pretreatment of small numbers of samples, the existing methods are cumbersome and inefficient.

[0026] (III) Beneficial Effects

[0027] The beneficial effects of this utility model are as follows:

[0028] 1. By driving the pressure plate through a downward pressing mechanism, the absorbent paper comes into close contact with the soil surface. Utilizing capillary action and mechanical pressure, it directly "absorbs" and "squeezes out" free water from the soil, significantly improving moisture absorption efficiency. Compared to traditional natural air drying, drying time can be shortened to within a few hours, making it particularly suitable for emergency testing or batch sample processing scenarios.

[0029] 2. Equipped with a manual turning mechanism, the comb-like structure turns the moist soil from the bottom layer to the surface, breaking down resistance to moisture migration and achieving uniform drying between soil layers. This design avoids the problem of moisture retention in the bottom layer after the surface layer dries, further shortening the overall drying cycle;

[0030] 3. The device achieves drying through physical pressure and capillary action, completely avoiding the damage of high temperatures to heat-sensitive components in the soil such as organic matter, volatile pollutants, or microorganisms, thus ensuring the authenticity and accuracy of the test results;

[0031] 4. The bottom of the pressure plate is connected to the absorbent paper hook side with Velcro. After the absorbent paper is saturated, you only need to lift the pressure plate to peel off the old paper and stick on the new paper. No tools are required throughout the process. The operation is simple and fast, reducing manual intervention and the risk of contamination. Attached Figure Description

[0052] The support rod 2 is vertically mounted on the base 1, and the first pipe clamp 3 and the second pipe clamp 4 are sequentially mounted on the support rod 2 along the vertical direction;

[0053] The base plate 5 is fixedly installed on the first pipe clamp 3;

[0056] The absorbent paper 9 is installed at the bottom of the pressure plate 7;

[0057] During use, the soil is laid in the tray 6, and the pressing mechanism 8 drives the pressure plate 7 to press down. The capillary action and pressure directly "suck out" and "squeeze out" the free water in the soil, which greatly improves the efficiency of soil pretreatment. The whole process is not heated, which completely avoids the damage of heat-sensitive components such as organic matter, volatile pollutants or microorganisms in the soil by high temperature, and ensures the authenticity and accuracy of the test results.

[0058] In this embodiment, the bottom of the pressure plate 7 is provided with a Velcro velvet surface, and the upper surface of the absorbent paper 9 is provided with a Velcro hook surface. When an absorbent paper 9 is fully saturated with water, simply lift the pressure plate 7 to easily peel off the old absorbent paper 9 and quickly attach a new one. The whole process is simple, fast, and requires no tools.

[0059] In this embodiment, the pressing mechanism 8 includes a lifting sleeve 81, a lifting rack 82, a spring 86, a limiting plate 85, a drive gear 83, and a drive swing arm 84.
