Embodiment Construction

[0045] The present invention will be further described below through specific embodiments.

[0046] like figure 1 , is a flow chart of a visual inspection and classification method for recycled aggregate containing mortar on the surface, including the following steps:

[0047] S101: Read the speed of the conveyor belt, and send the recycled aggregate scattered on the belt to the image acquisition area in turn by controlling the speed of the conveyor belt;

[0048] A feeding device is set on the conveyor belt, and the recycled aggregate on the feeding device is dropped onto the conveyor belt through vibration. By reading the speed of the conveyor belt, the speed of the conveyor belt is controlled to send the recycled aggregate scattered on the belt to the image acquisition area in turn;

[0049] S102: Scan the surface of the recycled aggregate moving on the conveyor belt with a color line scan camera to obtain an image containing the surface texture information of the recycled...

Abstract

The invention provides a visual detection classification method for recycled aggregate with mortar on the surface, which specifically comprises the following steps: reading the speed of a conveyor belt, and sequentially sending the recycled aggregate dispersed on the conveyor belt to an image acquisition area by controlling the speed of the conveyor belt; scanning the surface of the recycled aggregate moving on the conveyor belt through a color line-scan digital camera to obtain an image containing texture information of the surface of the recycled aggregate; preprocessing the image to obtain a preprocessed image, inputting the preprocessed image into a deep learning neural network, and determining information of each recycled aggregate; according to the information of each recycled aggregate, an air valve at an outlet of a conveying belt is controlled, and the recycled aggregate meeting the grade requirement is blown out; according to the method provided by the invention, different grades of recycled aggregates are separated by detecting the grades of the recycled aggregates, so that the grades of the recycled aggregates are detected, and the aggregates are classified.

Description

technical field [0001] The invention relates to the field of classification of recycled aggregates, in particular to a visual inspection and classification method of recycled aggregates containing mortar on the surface. Background technique [0002] With my country's continuous investment in infrastructure, the demand for aggregates is also rising, resulting in a serious shortage of primary aggregates in some areas. At the same time, the output of construction waste in my country is also increasing, and the pollution of many environments is more serious. As the main component of construction waste, waste concrete can be recycled into recycled aggregate, which can not only reduce the pollution of construction waste to the environment, but also alleviate the demand for primary aggregate. The recycled aggregate processed from waste concrete will have a direct impact on the grade of the aggregate due to the presence of mortar, and different grades of recycled aggregate will hav...
