[0002] Construction waste refers to the general term for slag, waste concrete, waste bricks and other wastes generated by people in the production activities of the construction industry such as demolition, construction, decoration, and repair. Construction waste is usually very heavy. In large factories with good production conditions, construction waste can be lifted by an overhead crane and then dumped into the treatment equipment; but in occasions with poor conditions, manpower is needed to lift the construction waste and pour it into the treatment equipment, which is time-consuming and laborious. Due to limited manpower, less construction waste can be dumped at one time, and the efficiency is low. In addition, construction waste is often piled up with various impurities, and it is inconvenient to dump it directly into the treatment equipment. Utility Model Content
