Description
Technical field
A kind of bulk solid laboratory automatic sieving unit is the utility model is related to, belongs to Geotechnical Engineering field.
Background technology
Because soil particle physical mechanics property confrontation engineering construction has important influence, it is therefore desirable to soil is carried out certain etc.
Level division so as to can be better understood by soil physico-mechanical properties.Native species is very more in nature and engineering properties is each
It is different, so grade classification is carried out to soil particle shows particularly important.The taxonomic hierarchies of soil is poor according to native engineering properties at present
It is different that soil is divided into certain classification, differentiated by different classification grades, it is valuable in order to be made between different great soil groups
Comparison, the evaluation of value.There are respective classification side in domestic sectors also according to respective engineering characteristic and practical experience, formulation at present
Method, but typically follow following basic principle.
First, concise principle：The index that the taxonomic hierarchies of soil uses, on the one hand want the Main physical power of concentrated expression soil
Property is learned, on the other hand also wants its evaluation of measuring method simple, it is easy to use.Second, the principle of engineering characteristic difference：Point of soil
The index that class system uses needs that its native engineering denominator and difference characteristic can be reflected to a certain degree.Such as when using remodeling
The test index of soil, when dividing the engineering properties difference of soil, for coarse-grained soil, its engineering properties depends on the individual particles of grogs
Feature, so conventional granulometric composition or grain composition grain group content carry out the classification of soil；For fine grained soil, its engineering properties is then adopted
With reflection grogs and the index of plasticity of aqueous phase interaction.
Native uniform categorisation system in the world（Unified Soil Classification System）From U.S.
State A. card Sa Grants（Casagrande, 1942）A kind of classification law system of proposition（Belong to the classification of material engineering system）.
The taxonomic hierarchies of Cattell U.S. Military airport engineering in World War II is applied, and joins after the war with American National reclamation of wasteland office
This method has been revised in conjunction.It is mainly characterized by having taken into full account the granulometric composition and index of plasticity of soil, i.e. coarse-grained soil grogs
The interaction of personal feature and fine grained soil grogs and water, but this method have ignored the set feature of grogs.
In China, for the discriminating of consolidated project soil, name and describe, while also allow for making generality to soil nature shape
Evaluation.Nineteen ninety has formulated national standard《The criteria for classification of soil》（GBJ145—90）, it is changed within 2007《The criteria for classification of soil》
（GB/T 50145—2007）》.Its taxonomic hierarchies substantially uses the principle of classification similar to Cattell, used easy to be easy
The quantitative classification index of survey, it can most reflect the base attribute and engineering properties of soil.The grain group of soil is divided into according to grogs grain scope
Three big macrosome, coarse grain and particulate system systems.
The purpose of soil classification is to recognize and identify the species of soil by classifying, and is the actual demand from engineering,
Studied and evaluated for different types of soil, to better profit from and transform the soil body, in order to reasonably design and adopt
Corresponding engineering measure is taken, reaches purpose economic, rationally, safe, adapts it to and meet engineering construction needs.Therefore, it is native
Classification be that the prospecting of rock mass engineering project construction, design, construction and staffing quota provide necessary basic foundation.
At present, it is at most sieve method soil classification to be used, although laboratory screening at present has automatic sieving machine,
But to rely on the artificial filling and collection for carrying out material.Therefore, the utility model is for laboratory sifter device
Deficiency develops bulk solid laboratory automatic sieving unit.This apparatus can realize laboratory bulk solid screening overall process
Automation, so as to the human and material resources saved and time.
The content of the invention
For the above-mentioned problems of the prior art and deficiency, the utility model provides a kind of bulk solid laboratory Automatic sieve
Separating device.The sieve of the bulk solid laboratory automatic sieving unit can be increased and decreased, the height of pan feeding and material-receiving system can from
Automation is realized to adapt to the height of Screening Network, pan feeding and discharging by adjusting, reduces human input.The utility model passes through following
