The construction waste is mainly screened for resource recovery, such as secondary utilization of cement. When the cement is recycled, the main working flow is that large cement blocks are firstly crushed into small cement blocks by a crusher (the cement blocks are generally crushed by a jaw crusher), then the small cement blocks are conveyed to an air screen device by a conveyer belt to be screened, and finally the small cement blocks after being screened are refined and crushed (the grinding and crushing adopt a crushing auger). However, in the screening process, some planar materials with large area (such as wallpaper adhered to large cement and insulation cotton layer in cement wall) are difficult to screen, and the large area of the planar materials is caused by the poor crushing effect (incapable of being crushed into small crushed materials) of the jaw crusher on the soft materials.
Referring to fig. 1 and 2, the reason is that in the air sieving process, the material is generally thrown by the material throwing device, and then the material is sieved by the airflow blown by the air blowing mechanism, but in the material throwing process, when the planar material is located at the lower layer of the material, when the material is thrown, the cement blocks located at the upper layer can press the planar material, so that the airflow cannot separate the light planar material from the heavy planar material.
In view of the foregoing, it is apparent that the prior art has inconvenience and disadvantages in practical use, and thus, needs to be improved.

The guide rods 205 located at the upper position are used for gathering the cement block materials (gathering scattered cement block materials to the middle position), in the material gathering process, the planar materials 500 located at the lower position of the material pile can be exposed, the clamping mechanism is convenient to position the planar materials 500, the working surface of the guide rods 205 located at the lower position is a curved surface (the working surface is a side surface far away from the air blowing mechanism 300), and the guide rods 205 located at the lower position are used for guiding the planar materials 500 to the space between the two guide rods 205, so that subsequent clamping is convenient.

referring to fig. 8 and 9, after the clamping rods 204 in the clamping state clamp the planar material 500, the two clamping rods 204 enter the raising state; the two clamping bars 204 are lifted upwards in a state that the ends of the two combined clamping bars 204 synchronously move upwards to a preset position (the preset height is higher than the height of the material pile transported by the conveyer belt 201) along the arc-shaped groove 203. The clamping rod 204 in the raising state can drive the guide rod 205 to raise one end of the planar material 500 to the upper position of the material pile conveyed by the conveyor belt 201, and under the cooperation action of the clamping rod and the conveyor belt 201, the planar material 500 is placed at the upper position of the material pile conveyed by the conveyor belt 201.
