Description

Technical Field

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

[0002] Soil testing is a crucial component in environmental monitoring, agricultural science, and geological exploration, and sample pretreatment is a key step in ensuring the accuracy and reliability of test data. Soil pretreatment typically includes operations such as drying, grinding, sieving, mixing, digestion, or extraction, with the aim of homogenizing the sample and extracting target components (such as heavy metals, organic pollutants, and nutrients) for subsequent instrumental analysis. However, traditional soil pretreatment methods suffer from low efficiency, cumbersome operation, and high pollution risks, necessitating more efficient and intelligent pretreatment devices. Natural air drying or oven drying is time-consuming, while manual grinding struggles to guarantee sample homogeneity, affecting the repeatability of test results. Therefore, we have redesigned a soil testing pretreatment device. Utility Model Content
