Description

Technical Field

[0001] This utility model relates to the field of soil sorting technology, specifically to a sorting mechanism for soil pretreatment. Background Technology

[0002] In fields such as soil testing, soil remediation, agricultural planting, and engineering construction, soil pretreatment is a crucial preliminary step, directly impacting the accuracy, efficiency, and quality of subsequent operations. Among the key requirements of soil pretreatment is the sorting and separation of large-volume gravel (typically referring to hard, blocky particles larger than 5mm in diameter, such as weathered rock fragments, construction waste, and natural rock particles). If this large gravel is not effectively removed, it will not only damage equipment during subsequent soil grinding, sieving, and digestion testing, leading to distorted data, but it will also affect the uniform mixing of remediation agents with the soil during remediation, reducing the remediation effect.

[0003] In the existing technology, the sorting method for large-volume gravel in soil is generally to use a vibrating screen. It uses a screen with a specific aperture to make soil particles pass through the screen holes by vibration, while gravel is intercepted and separated. However, during the screening process, gravel is large in mass, so it is easy for gravel to accumulate at the bottom of the soil, which affects the effect of soil passing through the screen holes and thus affects the soil sorting efficiency.

[0028] Working principle: During use, after the operator adds soil to the feed cylinder 6 through the feed hopper 8, the operation of the first motor 10 drives the screw rod 9 to rotate. Thus, the soil is fed into the screen cylinder 4 through the cooperation of the screw rod 9 and the feed cylinder 6. After the soil enters the screen cylinder 4, the operation of the second motor 14 drives the first gear 13 to rotate. At the same time, the meshing of the first gear 13 and the first gear ring 12 drives the screen cylinder 4 to rotate. The rotation of the screen cylinder 4 achieves the screening of soil and gravel. The screened gravel can be removed from the screen cylinder 4 by opening the mounting plate 15. During the screening process in the screen cylinder 4, the rotation of the screw rod 9 drives the stirring column 16 and the stirring rod 17 to rotate and stir the soil, thereby improving the efficiency of soil screening and gravel picking.
