Description

Technical Field

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

[0002] Soil samples are soil materials collected from the surface or subsurface of a specific area. They are fundamental materials for studying soil characteristics, directly reflecting the physical properties, chemical composition, and biological characteristics of the soil in that area. They provide crucial data support for agricultural production planning, environmental quality assessment, and geological exploration. Soil sample collection must adhere to scientific principles. The sampling depth, range, and quantity are usually determined according to the research objectives to avoid single-point biases affecting the accuracy of the results. After collection, samples need to be air-dried, ground, and sieved to remove impurities and standardize them for subsequent laboratory analysis. Through systematic research on soil samples, the laws of soil formation, fertility status, and environmental change trends can be revealed, making it an important bridge connecting theoretical research and practical applications.

[0003] Soil sample testing equipment encompasses rapid analytical tools for physical, chemical, and biological characteristics. For example, portable soil nutrient analyzers can determine nitrogen, phosphorus, and potassium content on-site, while laser particle size analyzers can quickly analyze soil particle composition. However, soil drying is often necessary before testing to prevent errors caused by soil moisture. With technological advancements, air-drying devices have become the core equipment in the soil pretreatment process. Their design focuses on efficiently and stably removing moisture from soil samples while preserving the original physicochemical properties of the samples to the maximum extent. However, such drying devices cannot sieve soil particles according to their size, resulting in inconsistent soil particle sizes and affecting the drying effect. Utility Model Content

[0041] Working principle: First, soil is put into the box 1 through the feed inlet 8. At this time, the soil falls into the screen box 201. Then, the cylinder 2072 is activated, and the cylinder 2072 will drive the push rod 2073 to extend and retract. At this time, the push rod 2073 will drive the fixed plate 203 to move. Under the action of the sliding rod 204 on the fixed plate 203, the scraper 202 will scrape against the top of the screen box 201. At the same time, smaller soil particles will fall into the drying box 5. After drying, the cylinder 2072 on the drying box 5 is activated. At this time, the cylinder 2072 will push the soil on the drying box 5 into the testing box 7 for testing. This realizes the ability to screen according to the size of soil particles, which is convenient for subsequent drying and can be tested separately.

[0042] First, pull the sliding rod 303 outward. At this time, the sliding rod 303 will stretch the spring 302, which will deform. Simultaneously, the sliding rod 303 will move the locking block 304 out. Then, slide the storage box 3052 out along the top of the slide rail 3051. The storage box 3052 will then slide out. Place the dryer into the storage box 3052 and reinstall it. At this time, the moisture in the soil can be absorbed through the circular holes 3062 on the square plate 3061. This allows for easy disassembly and installation of the storage box 3052, facilitating drying.
