Because the upper filter layer includes filter layer one and filter layer two, filter layer one is the same with the structure of filter layer two, consequently the clearance between two adjacent reinforcing bar A is equal, after the building rubbish landing of smashing goes up the upper filter layer, the granule that the granule is bigger than the clearance between two adjacent reinforcing bar A is stopped by reinforcing bar A and is no longer continued the decline, the building rubbish through the clearance between reinforcing bar A drops on the filter layer of lower floor, lower floor's filter layer at this moment is the horizontality, be convenient for accept the building rubbish that drops completely. At the moment, the first filter layer and the second filter layer are opened, when the first filter layer and the second filter layer completely move to the outer side of the upper-layer screening frame, the construction waste on the upper-layer filter layer falls onto the lower-layer filter layer, the particles of the construction waste on the lower-layer filter layer are all larger than the construction waste in the gap between the two adjacent steel bars B, the motor C is started, the lower-layer filter layer is in an inclined state, the inclined angle of the lower-layer filter layer is continuously adjusted, the construction waste on the lower-layer filter layer completely moves to the lifting mechanism, and therefore the construction waste cannot remain on the upper-layer filter layer and the lower-layer.

The operating principle of the screening mechanism in this application: and starting the motor B to enable the first filter layer and the second filter layer to be in a closed state, closing the motor B, and receiving the construction waste falling from the jacking mechanism by the first filter layer and the second filter layer at the moment, wherein the completely crushed construction waste and the construction waste with particles smaller than the gap between the adjacent steel bars A pass through the upper filter layer, the completely crushed construction waste falls on the conveyor through the lower filter layer, and the construction waste with particles larger than the gap between the adjacent steel bars B is left on the lower filter layer. And starting the motor B again to enable the motor B to rotate reversely, enabling the first filter layer and the second filter layer to gradually keep away from each other, completely separating the first filter layer and the second filter layer when the first filter layer and the second filter layer completely move to the outer side of the upper-layer screening frame, and turning off the motor B, wherein the construction waste on the first filter layer and the second filter layer falls onto the lower-layer filter layer at the moment, and because the width of the through hole A is equal to that of the first filter layer and the second filter layer, the construction waste on the first filter layer and the second filter layer is completely removed by the through hole in the separation process of the first filter layer and the second filter layer, namely, no construction waste remains on the first filter layer and the second. When the construction waste on the upper filter layer completely falls on the lower filter layer, the motor B is started again in the reverse direction, the screw rod A rotates, the first filter layer and the second filter layer are gradually closed to be in an original state, and when the first filter layer and the second filter layer are completely closed, the motor B is closed.

Starter motor C, motor C's the rotatory belt pulley A that drives of output shaft is rotatory, through the hold-in range, it is rotatory to drive belt pulley B, and then it is rotatory to drive lead screw B, lead screw B rotary drive sliding block moves on lead screw B, because the sliding block is pivot connection with lower floor's filter layer, consequently, the in-process that lower floor's filter layer removed, the one end of connecting rod is rotatory around the pin, and then the other end of connecting rod is rotatory around the axis of pivot, raise the one end of lower floor's filter layer through the connecting rod in the turn, consequently, lower floor's filter layer is the tilt state, be convenient for on the complete landing of building rubbish on the lower.

Referring to fig. 17: a lifting mechanism 6 is arranged on one side of the screening mechanism 4, the lifting mechanism 6 comprises a head end and a tail end, the head end of the lifting mechanism 6 receives the incompletely crushed construction waste, the tail end of the lifting mechanism 6 corresponds to the crushing mechanism 2, an electric push rod 7 is arranged at the tail end of the lifting mechanism 6, and the incompletely crushed construction waste on the lifting mechanism 6 is pushed to the crushing mechanism 2 by the electric push rod 7 to be crushed again;

lifting mechanism 6 is Z type conveyer, and lifting mechanism 6's head end corresponds with lower floor's filter layer 43, and lifting mechanism 6's end sets up electric putter 7, is provided with push pedal 71 on the electric putter 7, and push pedal 71 is just setting up feeder hopper 21.

One side of the tail end of the lifting mechanism 6 is provided with a protective plate 61, and a push rod seat of the electric push rod 7 is fixedly connected with the protective plate 61.

The working principle of the lifting mechanism in the application is as follows: a complete circular crushing process is formed by the lifting mechanism, and the construction waste which is not completely crushed is conveyed back to the feed hopper to be crushed by the providing mechanism, so that the circular crushing process of the construction waste is realized.
