Automatic aggregate granularity and particle shape detection system

Abstract

The invention discloses an automatic aggregate granularity and particle shape detection system which comprises a cabin, a feeding device, a conveyer belt, an image acquisition device, a control device, a man-machine interaction interface display device and a wireless transmission device, wherein the cabin is used for storing aggregate; the feeding device is arranged below the discharge end of thecabin and is used for receiving and conveying the aggregate to the conveyer belt; the image acquisition device comprises a camera; the camera is arranged above the conveyer belt and used for acquiringimages of the aggregate conveyed on the conveyer belt; the control device is connected with the camera and used for receiving and processing image information fed back from the image acquisition device, of the aggregate; the man-machine interaction interface display device is connected with the control device and used for displaying information processed by the control device and used for inputting operation instructions; the wireless transmission device is connected with the control device and used for transmitting aggregate information processed by the controlling device to wireless terminal equipment. Through mutual cooperation of components, rapid on-line detection on aggregate granularity and particle shapes can be achieved, and aggregate grading situations of an aggregate productionline can be reflected in time.

Description

technical field [0001] The invention belongs to an aggregate detection device, in particular to an automatic detection system for aggregate particle size and shape. Background technique [0002] With the development of urban construction in our country, concrete, as an important material for infrastructure and urban construction, bears a major responsibility in the construction of new urbanization in our country. Fine aggregate is the main component of concrete, accounting for about 30% to 40% of the total volume of concrete. The reason for the current concrete performance problems is largely due to the unqualified fine aggregate quality, such as poor aggregate particle shape, poor gradation, large porosity, many needle-like particles, and high stone powder content. Unqualified fine aggregate quality will affect concrete water consumption, cementitious material consumption, durability, etc. To ensure the performance of concrete, it is not only necessary to improve the leve...

Problems solved by technology

[0003] Particle size and particle shape are two important control parameters of fine aggregate. The size and distribution of particle size will affect the particle gradation of aggregate. The traditional detection method of aggregate gradation is manual off-line screening detection, which is time-consuming and labor-intensive. Energy consumption, cannot reflect the particle size and distribution of the aggregate in time, and cannot detect the particle shape. When flaky and needle-shaped aggregates are included, on the one hand, it will affect the particle size detection accuracy, and on the other hand, it will affect the concrete mixing. composite strength quality

[0004] There are many problems in the existing on-line detection equipment for concrete aggregates, such as time-consuming and labor-intensive, only sampling detection, and the defects that online detection cannot be realized, the defect of aggregate particle shape detection can only be detected one by one, and there are aggregate particle Defects that cannot be detected simultaneously
