[0002] Concrete is a general term for engineering composite materials that are made of cementitious materials that bind aggregates into a whole. In engineering construction, concrete is the most common and indispensable engineering material. For example, when reinforcing dangerous rock masses, concrete is an indispensable material. By spraying concrete onto the surface of dangerous rock masses, a solid protective layer can be formed to increase the overall strength and stability of the rock mass. At present, concrete is generally processed by concrete mixing plants. Concrete can be processed by transporting processed raw materials such as cement and aggregates to concrete mixers for mixing.
[0003] When existing concrete mixing plants are conveying aggregates, there are often some larger particles in the aggregates. Therefore, screens and vibration mechanisms are set up to screen the large particles. However, in actual applications, the screening mechanism often cannot automatically adjust the vibration frequency according to the conveying amount of aggregates. As a result, when the conveying amount increases, the screening effect is poor and the screen is easily blocked. Therefore, an intelligent control device for a concrete mixing plant is proposed.
