Description

Technical Field

[0001] The invention relates to the technical field of air-drying soil samples, and in particular to air-drying processing equipment after soil sampling. Background Art

[0002] Soil composition detection is one of the routine soil detection items. The soil composition detection method is easily affected by the following factors, including: soil moisture, soil particle size, impurity content, soil density, etc.; therefore, in the detection and testing process, in order to improve the accuracy of the detection and analysis, it is often necessary to quickly dry, screen and separate impurities from the soil samples. Effective pre-treatment plays an important role in improving the accuracy of the detection; before the soil sample detection, the collected soil samples need to be air-dried, then ground and sieved for detection. A large number of soil samples need to be air-dried for air-drying, and a large number of sample containers are placed. Generally, the soil sample detection laboratory uses enamel trays to place the samples to be air-dried. Small enamel trays can hold a small amount of samples. When the number of samples required for the test is large, it is difficult to air-dry more soil piled on small enamel trays. One sample is placed on different sample trays. When the number of samples is large, it is easy to confuse the samples. Using large enamel trays takes up a lot of space; some laboratories spread the samples on clean paper for air-drying, which not only takes up a lot of space, but also makes the samples easily confused and cross-contaminated;

[0003] Therefore, it is necessary to use soil sample air drying equipment for air drying. Existing soil sample air drying equipment usually places the soil sample to air dry, and cannot perform operations such as blowing, stirring, and heating on the soil sample. The drying efficiency is low, and the soil sample is prone to compaction during the air drying process, resulting in poor soil air drying effect, and it is impossible to air dry the soil sample efficiently and with high quality.

[0004] However, the air-drying device that can achieve high-quality soil samples is expensive because its internal structure is too complicated, and due to the limitations of the sample chamber, the number of samples that can be dried at one time is relatively small.

[0005] Therefore, it is an urgent problem to provide a soil sample air-drying device that can achieve high-quality air-drying and has a simple structure and low cost. Summary of the invention
