At this time, the rotating tube 5 and the spiral blade 18 rotate in the opposite direction, thereby lifting the crushing rod 19 Due to the crushing effect, the construction waste finally falls downward through the material drop opening 16 and falls on the top of the filter plate 24, and then slides downward according to the inclination direction of the filter plate 24. At this time, the construction waste smaller than the through hole 25 will It falls on the top of the guide plate 27 through the through hole 25. At this time, the electric push rod 29 pushes the guide plate 27 through the contact block 30, so that the guide plate 27 slides inside the fixed block 26, thus speeding up the removal of construction waste and making it The interior of the device is discharged through the second discharge port 31, and construction waste larger than the through hole 25 will slide downwards following the surface of the filter plate 24 and enter the inside of the collection box 20, while the filter screen 21 will remove the larger construction waste. The construction waste is blocked so that it continues to accumulate on the top of the filter 21, and the smaller construction waste will directly pass through the filter 21 and fall inside the storage box 22. After a certain period of time, the device will be closed, and then the storage box will be closed. The box 22 is pulled out, the smaller construction waste inside is poured out, and the larger construction waste at the top of the filter 21 is poured into the device again for secondary crushing.
