Screening device for soil detection

Abstract

The invention relates to the field of soil detection, in particular to a screening device for soil detection. The screening device comprises a fixed box, wherein a first filtering mechanism is arranged inside the fixed box, one end of the first filtering mechanism penetrates through and extends out of the fixed box and is fixedly connected with a driving mechanism, and a supporting mechanism is arranged at the end, located inside the fixed box, of the first filtering mechanism. During use, a conveying sleeve can be driven by a driving motor to rotate, and the conveying sleeve drives a soil sample to roll inside the conveying sleeve through conveying blades so that large sundries can be left in the conveying sleeve to be discharged, fine soil falls into a fixing hole from filtering holes, and meanwhile, the conveying sleeve drives a fixing seat to do ascending and descending motion through transmission so that the fixing seat can be driven to shake, and soil can be screened again through a filtering net plate in the fixing hole, so that the soil sample can be screened very efficiently.

Description

technical field [0001] The invention relates to the field of soil detection, in particular to a screening device for soil detection. Background technique [0002] Soil environment monitoring refers to determining the 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 monitoring refers to soil environmental monitoring, which generally includes technical content such as point sampling, sample preparation, analysis methods, result characterization, data statistics, and quality evaluation. With the development of science and technology, there are more and more factories. However, The factory produces a large amount of pollutants in production, and discharges them to different places such as rivers and lakes through sewage pipes, which causes water and land pollution. If the quality is not timely, it will cause damage to the ecolog...

What we usually refer to as soil monitoring refers to soil environmental monitoring, which generally includes technical content such as point sampling, sample preparation, analysis methods, result characterization, data statistics, and quality evaluation. With the development of science and technology, there are more and more factories. However, The factory produces a large amount of pollutants in production, and discharges them to different places such as rivers and lakes through sewage pipes, which causes water and land pollution. If the quality is not timely, it will cause damage to the ecological environment. In order to protect the environment Governance and monitoring, soil testing is required to manage environmental issues

[0003] After the existing part of the soil is collected, it will contain some stones and other debris inside, and these substances will affect the results of the soil test during the test, so it is necessary to screen the soil sample before the test. , it is necessary to propose a screening device for soil testing
