[0017] like Figs. 1-2 The present invention provides a rapid detection device for fine aggregate powder content, comprising: a bottom platform 12, a high-definition digital camera 7, an electronic balance 16, and a sample container 15; a vertical support 1 is fixedly installed on the bottom platform 12, and a top bracket 3 is provided on the upper part of the vertical support 1. A diagonal brace 2 is installed between the vertical support 1 and the top bracket 3 for reinforcement connection. A first light source 5 and a second light source 11 are symmetrically arranged on the top bracket 3; the high-definition digital camera 7 is connected to a terminal 8 through a data transmission line 6, and an elastic clamp 9 is provided at the end of the top bracket 3 through a fixing pin 4. The elastic clamp 9 is used to clamp the high-definition digital camera 7; the electronic balance 16 is positioned by a positioning block 13 on the bottom platform 12, and the fine aggregate sample 14 is placed in the sample container 15 and then placed flat on the top of the electronic balance 16 as required; the high-definition digital camera 7 has a camera 10 on the side facing the electronic balance 16, and the first light source 5 and the second light source 11 are designed to enhance the recognition accuracy of the camera 10.

[0018] Specifically, the bottom of the vertical support 1 is fixedly installed on the bottom platform 12, and the top of the vertical support 1 is reinforced with the connection between it and the top bracket 3 by the diagonal support 2; the high-definition digital camera 7 is temporarily and adjustablely fixed to the top bracket 3 by the elastic clamp 9, and the elastic clamp 9 can be quickly replaced as needed; the terminal device 8 is connected to the high-definition digital camera 7 through the data transmission line 6, and a first light source 5 and a second light source 11 are symmetrically installed on the top bracket 3 to optimize the detection environment. The terminal device 8 is equipped with professional image processing software to achieve fast and accurate mica detection. Measurement; the positioning block 13 is fixedly installed in the middle of the bottom platform 12, and the electronic balance 16 can be quickly positioned and limited by the positioning block 13 to improve the accuracy and convenience of the test; after the sampling and processing steps, the fine aggregate sample 14 is placed flat in the sample container 15, and at the same time, it is placed securely on the top of the electronic balance 16 according to the test requirements. The camera 10 takes multiple sets of photos of the fine aggregate sample 14 in the sample container 15 and transmits them to the terminal device 8 for processing and analysis, so as to simply and efficiently determine the mica content in the sample.

[0019] The detection process using the aforementioned rapid detection device for fine aggregate powder content is as follows:

[0020] 1. Randomly select fine aggregate samples 14 to ensure that the weight of multiple samples is consistent. After drying the samples according to the test requirements, scrape them flat and put them into the sample container 15.

[0021] 2. Use the fixing pin 4 to fix the elastic clamp 9 to the top bracket 3, install the high-definition digital camera 7 between the elastic clamps 9, and use the data transmission cable 6 to connect the camera and the terminal device 8.

[0022] 3. Using the positioning block 13 on the bottom platform 12, install the electronic balance 16 in the designated position. Then place the sample box 15 flat on top of the electronic balance 16, while ensuring that the fine aggregate sample 14 is directly below the camera 10.

[0024] 5. After taking multiple sets of photos that meet the requirements for fine aggregate sample 14, use professional image processing software (such as Photoshop) on terminal 8 to number and save them. For the same fine aggregate sample 14, select 3 photos with small differences according to the average value of the image in memory as the analysis samples.

[0025] 6. By establishing a standard photo pixel curve based on mica particles in fine aggregate, and comparing the photo analysis sample with the pure mica standard curve, efficient and accurate measurement can be performed, thereby improving the quality control of fine aggregate.

[0026] In the detection of fine aggregate powder content, the fine aggregate powder mainly refers to mica, as mica and sand exhibit significant differences in particle morphology and color. Therefore, under consistent compression ratios and the same size settings, variations in the ratio of mica to sand in the fine aggregate directly affect the memory usage after imaging. To accurately determine the mica content, pure mica particles are first separated from the fine aggregate raw material, dried, and then photographed to clarify the correlation between the mica content and the memory usage of the digital image in the pure mica particle state, thus constructing a standard curve. Subsequently, the fine aggregate sample 24 to be tested undergoes sampling, drying, and photographing. The memory usage value of the image generated from the fine aggregate sample 24 is combined with the previously established pure mica particle standard curve, and an in-depth analysis is conducted using the interpolation method to accurately calculate the mica content in the fine aggregate sample.

However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
