[0002] Construction waste refers to the excavated soil, materials, and other waste generated during the construction, renovation, expansion, and demolition of various buildings, structures, pipelines, and the decoration and renovation of houses. This construction waste needs to be recycled and disposed of to avoid polluting the surrounding environment. A lot of construction waste is often generated during construction.

[0003] In the current process of recycling and screening construction waste, it may be impossible to clear the screening screen, which will cause the screen to become clogged during long-term screening. This requires maintenance and cleaning by staff, which reduces the screening efficiency of construction waste, slows down the work process and efficiency, and makes it difficult to vibrate the screening plate properly during screening, resulting in slow screening. Therefore, a construction waste stone grading and screening device is proposed. Utility Model Content
