Description

Technical Field

[0001] The utility model relates to the technical field of construction waste recycling, in particular to a construction waste recycling device that is convenient for screening. Background Art

[0002] When developing and innovating in the construction industry, old buildings and materials need to be demolished. After demolition, large areas of construction waste are piled up, which not only affects the city appearance, but also easily hinders the development of buildings. When processing construction waste, construction waste recycling equipment is needed. When using it, the construction waste is crushed by crushing equipment, and the fine materials and granular materials are recycled and utilized;

[0003] A commonly used screening method is to pour construction waste into a screening device for filtering. During screening, since large-area buildings are poured into the screening device together, some small construction waste is squeezed in the middle by large construction waste and cannot be screened out through the screen. When the large construction waste is discharged, it is discharged with the small construction waste that has not been screened out. Therefore, it is necessary to screen the construction waste for the second time. Multiple screening will waste time and increase the work of the staff, making the staff more tired.
