[0002] With the acceleration of urbanization, a large amount of construction waste is generated by building demolition and new building projects. Among them, the proportion of waste concrete is large. According to statistics, waste concrete accounts for about 30%-40% in construction waste. If these large amounts of waste concrete are not treated, they will occupy a large amount of land resources, and many construction waste storage sites become pollution sources around cities. For example, some construction waste landfills around large cities not only waste land, but also, under the rainwater scouring, harmful substances in the construction waste can seep into the soil and groundwater, causing serious damage to the ecological environment. Therefore, in order to effectively treat these waste concretes, a recycled concrete raw material crushing device emerges as the times require.
[0003] The prior art uses a jaw crusher to crush concrete raw materials. The movable jaw plate makes periodic reciprocating motion on the fixed jaw plate. When the movable jaw plate approaches the fixed jaw plate, the materials are crushed by extrusion, splitting and bending. When the movable jaw plate moves away from the fixed jaw plate, the materials that have been crushed to less than the size of the discharge port are discharged, and the larger particles of materials remain in the crushing chamber and continue to be crushed by the next extrusion. However, the inner wall of the crushing device is damaged due to the strong impact and friction of the concrete and other materials, which is difficult to repair. SUMMARY
