[0002] Ordinary concrete refers to artificial stone made mainly of cement, combined with water, sand, stones, and when necessary, chemical admixtures and mineral admixtures, proportioned appropriately, and formed into a dense shape through uniform mixing and cured and hardened. Concrete is mainly divided into two stages and states: the plastic state before setting and hardening, namely fresh concrete or concrete mixture, and the hard state after hardening, namely hardened concrete or concrete.

[0003] Currently, the commonly used concrete recycling devices usually consist of a crushing component and a screening component. However, when recycling waste concrete, a large amount of dust is often generated, which not only pollutes the environment but also easily damages the inside of the machine. After the crushed concrete is screened, it will fall into a specific receiving trough, but the staff needs to replace the receiving trough regularly to prevent the overflow of concrete waste, and the work efficiency of the staff is easily affected. In view of such a situation, we have proposed a waste concrete recycling device. Content of the Utility Model

A paired feeding port is provided at the bottom of the recycling box, and the feeding port corresponds to the screw conveying shaft. The paired second motors are respectively connected to the paired screw conveying shafts.

[0007] Preferably, the first filter hole at the upper end of the filter plate is smaller than the second filter hole at the lower end.
