Description

Technical Field

[0001] The utility model relates to the technical field of soil detection, in particular to a soil impurity removal device for soil detection. Background Art

[0002] Soil testing is an important process of analyzing soil samples to understand their chemical, physical and biological properties. Through testing, we can obtain information on the nutrient content, organic matter ratio and possible pollutants in the soil. These data are crucial for agricultural production, environmental protection and land management. Soil samples need to undergo a series of pre-treatment steps before testing, among which impurity removal is a crucial link.

[0003] A Chinese patent discloses a soil impurity removal device for soil testing (publication number CN219596838U). This patented technology adds soil to the inner cavity of a drying box through a feed pipe. A hot air blower can deliver hot air to the inner cavity of the circular tube. The hot air is discharged through the air outlet holes on a plurality of drying stirring rods, thereby drying the soil. However, during the drying process, the drying stirring rods are in direct contact with the soil, and fine dust in the soil can easily enter the air outlet holes on the drying stirring rods, causing blockage and resulting in poor drying effect.
