Description

Technical Field

[0001] The utility model relates to the technical field of crushing devices, in particular to a crushing device for road bridge and tunnel construction. Background Art

[0002] During the construction of roads, bridges and tunnels, a large amount of construction waste will be generated due to operations such as excavation, construction and demolition. If these wastes are discharged directly without treatment, it will not only cause a waste of resources, but also may cause serious pollution to the environment. There are two main ways to deal with waste in road, bridge and tunnel construction: one is direct landfill. Although this method is simple and easy, it will occupy a lot of land resources and easily cause secondary pollution; the other is to crush it through crushing equipment, and then utilize it as a resource or treat it harmlessly. Among them, the second method has been widely used due to its advantages of high efficiency and environmental protection.

[0003] The existing crushing devices for road, bridge and tunnel construction do not have a screening function during the processing process. Most of them are directly crushed by crushing rollers and then directly discharged. It is difficult to effectively separate the useful components and useless components in the waste, which reduces the practicality of the crushing device. Therefore, a crushing device for road, bridge and tunnel construction is proposed to solve the above problems. Utility Model Content
