Description

Technical Field

[0001] The utility model belongs to the technical field of soil screening, and in particular relates to a soil screening device used for soil detection. Background Art

[0002] Soil pollutant detection is an essential part of soil environmental protection and governance. Due to the high spatial heterogeneity of the soil environment, the composition of soil samples is often complex and mixed with a large amount of impurities such as stones, gravel, and plant roots, which seriously affects the accuracy and representativeness of the test results.

[0003] After searching, the publication number: CN220111526U discloses a screening device for soil improvement detection. In the utility model, the screening component utilizes eccentrically nested screen barrels and collecting barrels as screening parts. Under the action of the motor and the rotating rod, the screen barrel rotates eccentrically inside the collecting barrel; the effective material will follow the collecting barrel into the inside of the discharge hole to achieve the collection effect. The material receiving component designs the collecting barrel as an inverted cone structure, so that the material collected inside can be summarized into the discharge hole; the funnel installed on the discharge hole is used to collect the material in real time, and then summarize the material into the inside of the material trough. Although this device has a soil collection effect that is convenient for screening, it is difficult to achieve screening of moist soil, so that the whole can only achieve the screening work of dry soil, reducing the overall screening quality and applicability.
