Existing multi-stage screening and recycling devices for concrete waste have certain limitations in their use.

[0003] An existing concrete waste recycling device for civil engineering, as described in Chinese patent application number CN202222017783.7, includes a recycling box with a material discharge port in the middle of the top. Dust removal mechanisms are located on both sides of the top of the recycling box. A crushing box is installed in the middle of the inner side of the recycling box, with arc-shaped guide plates installed on both sides and near the top of the crushing box. A crushing mechanism is located inside the crushing box. A movable cavity is located at the front end of the recycling box near the bottom, and a collection box is movably installed inside the movable cavity. The collection box is located below the crushing box, and a T-shaped plate is vertically connected to the middle of the inner side of the collection box. Screening components are installed on both sides of the T-shaped plate, and clamping plates extend upwards from both ends of the T-shaped plate. However, existing concrete waste recycling equipment requires screening after crushing the concrete, but the existing screening structure cannot achieve efficient screening and is prone to clogging.
