6. A green demolition method of construction waste as claimed in claim 5 wherein in S14, the concrete and brick separating device includes a body, a vibrating plate is obliquely disposed in the body, the vibrating plate is connected to a vibrating motor disposed inside the body, a connecting seat is disposed at a distal end of the vibrating plate, a separating screen is disposed at one side of the connecting seat, a head end of the vibrating plate is communicated with a feeding bin located at an upper portion of the body, an air filtering device is disposed on the body at one side of the feeding bin, the air filtering device filters material dust generated during vibration, and filtered air is discharged from the air filtering device.
7. The method for green demolition of construction waste as defined in claim 6, wherein a vibration plate groove is formed at a lower portion of the connection seat, the vibration plate extends into the vibration plate groove, buffer springs are provided at both sides of the vibration plate groove, one end of the buffer spring is connected to the vibration plate, a connection plate is provided at an upper portion of the vibration plate groove, and a discharge hole is provided at an upper side of the connection plate, the discharge hole discharging the vibrated material out of the vibration plate.
8. A green demolition method of construction waste as claimed in claim 7 wherein after the material enters the separating screen, the small particle size concrete falls from the separating screen to the gravel exit, the larger bricks cannot fall, so that the bricks continue to advance to the brick exit, at this time, the gravel exit discharges the small particle size concrete, the brick exit discharges the bricks, and the separation of the concrete and the bricks is achieved.
9. A green demolition method of construction waste as claimed in claim 8 wherein a limiting plate is provided at the upper part of the discharge port, the limiting plate limits the flow of the discharge port, ensures that the material flows out to the separation sieve at a constant speed for separation, and prevents the material from piling up so that the concrete and the bricks cannot be separated completely.
10. A green demolition method of construction waste as claimed in claim 9 wherein the connection plate is trapezoidal and includes a loading surface, a connection surface, a unloading surface in sequence, the material enters from the end of the vibration plate to the loading surface, since the following material is pushed to continuously advance to the connection surface and finally to the unloading surface, the unloading surface falls directly to the separation sieve for separating concrete and brick.
