Soil detection pretreatment system and method thereof

Abstract

The invention provides a soil detection pretreatment system and method. The soil detection pretreatment system comprises a soil separation antifouling device, a soil grinding device, a soil air drying device and a soil weighing device which are sequentially connected from feeding to discharging. The soil separation anti-fouling device comprises a base disc, a soil storage barrel is connected to the base disc in a sliding mode, the center of the soil storage barrel is in driving connection through a transposition motor, a plurality of independent storage cavities are evenly formed in the periphery of the soil storage barrel, a top opening of each storage cavity is covered with a sealing cover, and a discharging opening is formed in the base disc. The bottom opening of any storage cavity is communicated with the discharge outlet in a matched mode, the lower portion of the discharge outlet is connected with a top opening of the conveying pipeline, the head end of the conveying pipeline is connected with the high-pressure fan, and the tail end of the conveying pipeline extends towards the next station. Through mechanical cooperation, automatic operation of isolation storage, grinding, air drying and weighing is sequentially carried out, and the grinding effect of high uniformity and comminution of soil is achieved. And cross contamination among different samples is avoided.

Description

technical field [0001] The invention belongs to the technical field of machinery, in particular to a soil detection pretreatment system and a method thereof. Background technique [0002] After weathering, the rocks on the earth's surface are gradually broken into loose mineral particles of various sizes (called parent materials). Soil is formed and evolved under the comprehensive action of various soil-forming factors such as parent material, climate, organisms, topography, and time. The composition of soil is very complex. Generally speaking, it is composed of three phases of solid, liquid and gas such as minerals, organic matter produced by the decomposition of animal and plant residues, water and air. [0003] Soil environment monitoring refers to the determination of environmental quality (or pollution degree) and its changing trend through the determination of representative values ​​of factors affecting soil environmental quality. What we usually refer to as soil mo...

AI Technical Summary

Problems solved by technology

[0006] 1. The soil particles after grinding are not uniform, and the grinding effect is poor;

[0007] 2. The existing grinding equipment is easy to mix different soil samples, resulting in cross-contamination and affecting the accuracy of soil analysis

[0008] The soil must be tested when it loses moisture and is completely dry, but the soil sample cannot be heated and dried, because the trace elements contained in the soil will undergo chemical changes and be lost during the heating process, so the existing technology can only make Soil samples are air-dried in the natural state. This air-drying method is relatively traditional and inefficient. The soil samples are easily polluted by external dust during the air-drying period.
