System and method for rapidly and automatically detecting entrance of concrete sand

Abstract

The invention provides a rapid automatic detection system and method for entering of concrete sand. The system comprises an automatic sampling module, a moisture content automatic detection module, a material homogenization module, a particle material image analysis module, an automatic screening module, a silt content detection module and a control module. The automatic sampling module is used for sampling whole vehicle sand; the water content automatic detection module is used for detecting the water content of the whole sand at different depths; the material homogenizing module is used for stirring and homogenizing the sample; the particle material image analysis module is used for detecting the grading and fineness modulus of the sample; the automatic screening module is used for filtering the sample; the silt content detection module is used for detecting the silt content of the sample. The water content, the sand fineness modulus, the sand gradation and the sand mud content of the whole vehicle sand are automatically detected, manual operation is not needed, the automation degree and the intelligence degree of sand entering detection are improved, a large amount of time and manpower are saved, the sand detection time is shortened, and the sand detection precision is improved.

Description

technical field [0001] The invention relates to the technical field of sand detection equipment, in particular to a system and method for rapid and automatic detection of concrete sand entering a site. Background technique [0002] Concrete is currently the largest man-made material and the most important building material. The role of sand and gravel aggregate in concrete is very important. It acts as a skeleton and transmits stress. Even without cement paste, aggregate can support load, while inhibiting shrinkage and preventing cracking. Therefore, after the whole vehicle sand enters the site, the sand needs to be tested before unloading. [0003] At present, most of the detection of sand is through manual sampling, and then manually detect the moisture content, sand fineness modulus, sand gradation, sand mud content or stone powder content of sand samples. There are problems such as a low degree of automation, a large amount of time and manpower, and the detection accur...
