Description

Construction waste crushing and screening integrated machine Technical Field The utility model relates to the technical field of construction waste crushing and sorting, in particular to a construction waste crushing and screening integrated machine. Background Along with the acceleration of the urban process and the vigorous development of the building industry, the generation amount of building waste is increased, wherein the building waste plates occupy a considerable proportion, and the waste plates comprise wood plates, metal plates, plastic plates, composite plates and the like, are largely abandoned in the process of processing the building waste plates in the process of dismantling, decorating or reforming the building, screen recoverable substances such as metal, light plastics and the like, and have important significance for improving the resource recycling rate and reducing the processing cost; The traditional screening mode generally picks up the wastes such as plastic bags, waste metals and the like by manpower near the conveyor belt, and the problems of low efficiency, incomplete screening and the like often exist, so that the requirement of large-scale construction waste treatment is difficult to meet. Disclosure of utility model The utility model aims to solve the technical problems that the existing screening mode generally picks up the waste such as plastic bags, waste metals and the like by manpower near a conveyor belt, and the problems of low efficiency, incomplete screening and the like are caused, so that the requirement of large-scale construction waste treatment is difficult to meet. In order to solve the problems, the technical proposal adopted by the utility model is that the construction waste crushing and screening integrated machine comprises a frame, wherein three pairs of crushing rollers are rotationally arranged on the inner side of the frame, a first conveying belt mechanism and a second conveying belt mechanism are respectively arranged between every two pairs of crushing rollers, an air box is fixed on the inner side of the frame above the first conveying belt mechanism, an air outlet is arranged on the upper side of the frame above the air box, the air delivery upside is fixed with the protection frame, and the frame upside is located conveyer belt mechanism two tops and has offered the opening, and opening upside both ends are fixed with the articulated frame, rotate between the articulated frame and are equipped with the live-rollers, and the live-rollers side is spacing to be inserted and is equipped with a plurality of magnet stick, and frame upside is located the live-rollers and is fixed with delivery board one side, and delivery board one end contacts with magnet stick surface. As a further proposal of the utility model, the crushing fineness of the three pairs of crushing rollers gradually increases from top to bottom so as to facilitate the fine crushing of the plate waste and simultaneously facilitate the extraction of waste metal and light plastics therein. As a further scheme of the utility model, a plurality of air holes are formed on the upper side of the air box, the air box is positioned below one side of the top crushing roller, and the air direction of the air box faces the air conveying port, so that the light plastics can be conveniently winnowed.
