Description

Technical Field

[0001] This utility model belongs to the field of experimental equipment technology, specifically relating to a rapid pretreatment device for soil microbial detection samples. Background Technology

[0002] Soil microbial testing confirms the activity of soil microorganisms, which helps to solve soil problems. Soil microbial activity indicates the status of the entire microbial community or some specific populations in the soil, and can reflect subtle changes in the natural or farmland ecosystem.

[0003] Pretreatment of soil microbial test samples is a critical step affecting the accuracy of the test. It is usually done in steps using separate equipment: first, the soil is crushed by a grinding device, then impurities are filtered by a vibrating sieve, and finally, large particles are removed manually. The existing step-by-step operation results in sample transfer losses, and the switching between grinding and sieving equipment increases time costs. At the same time, the static filter screen is prone to clogging, requiring frequent shutdowns for cleaning. It is particularly ineffective at separating adhesive impurities in water-containing soil, which greatly reduces the efficiency of soil crushing and filtration. In addition, the multiple processing steps increase the labor intensity of the staff and result in a waste of time and human resources. Utility Model Content
