After the concrete block without the steel bars passes through the temperature sensor 53, the temperature sensor 53 does not work, an included angle between the material distribution plate 54 and the fixing plate 58 is 45 degrees under the action of the first spring 57, so that the concrete block without the steel bars is prevented from continuously running on the feeding transmission belt, and the concrete block falls off from the feeding transmission belt 1 under the prevention of the material distribution plate 54; after the concrete piece that contains the reinforcing bar passes through temperature sensor 53, temperature sensor 53 control an electro-magnet 55 work, and then an electro-magnet 55 produces the suction to iron plate 56, and iron plate 56 drives branch flitch 54 and moves to fixed plate 58 direction, and then can not hinder to the concrete piece that contains the reinforcing bar, and the concrete piece that contains the reinforcing bar continues to move on feeding conveyer belt 1, until entering crushing mechanism 4. The temperature that contains the concrete piece of reinforcing bar through alternating magnetic field generator 51 back reinforcing bar risees, and the parcel is unchangeable at the concrete temperature outside the reinforcing bar, the reinforcing bar can produce certain inflation deformation after being heated, the reinforcing bar can produce the outside extrusion force of certain direction to the reinforcing bar in concrete inside, the temperature of concrete this moment is unchangeable, the volume is unchangeable, so the inside stress that receives of concrete can make the concrete change, thereby help on next step its breakage.
The baffle mechanism 52 comprises a support rod 521, a transverse plate 522 and a torsion spring 523, one end of the support rod 521 is fixedly connected with the support frame 3, one end of the transverse plate 522 is movably connected with the transverse rod, one end of the torsion spring 523 is fixedly connected with the support rod 521, one end of the torsion spring 523 far away from the support rod 521 is fixedly connected with the transverse plate 522, two baffle mechanisms 52 are arranged, and the two baffle mechanisms 52 are close to each other on a feeding transmission belt. Two baffle mechanisms 52 are arranged at the same position on the feeding conveyor belt 1, so that concrete blocks passing through the baffle mechanisms 52 can be subjected to resistance, and then sequentially pass through the baffle mechanisms 52 one by one, and the purpose that the concrete blocks sequentially enter the distributing mechanism 5 is achieved. When the concrete block contacts the cross plate 522, the cross plate 522 is pushed by the pushing force, and when the pushing force is larger than the elastic force of the torsion spring 523, the cross plate 522 is pushed away by the concrete block, and the concrete block passes through the baffle mechanism 52 and enters the material dividing mechanism 5.

When the volume of a general concrete block is large, the volume of the reinforcing steel bars inside the concrete block is also large, that is, the temperature of the large-volume concrete block is high, after the high-temperature reinforced concrete block enters the housing 41, the temperature inside the housing 41 rises, and then the air bag 492 inside the rotor 45 is heated to expand, the expansion of the air bag 492 enables the volume of the air bag 492 to increase, and then the air bag 492 can push the lug 46 to move towards the direction away from the center of the rotor 45, that is, the length of the lug 46 extending out of the rotor 45 is increased, so that the area of the part of the large-volume concrete block, which is in contact with the lug 46, is increased, the concrete block starts to make a circular motion together with the rotor 45 under the shearing force of the lug 46, and then flies out to collide with the crushing plate 47 to be crushed under the action of the centrifugal force. When a concrete block with a small volume enters the shell 41, the temperature is low, the bump 46 moves towards the direction close to the circle center of the rotor 45 under the action of the second spring 493, and the length of the part extending out of the rotor 45 is short, so that the concrete block starts to do circular motion together with the rotor 45 under the action of the shearing force of the bump 46, the flying out of the concrete block cannot be influenced under the obstruction of the bump 46, and the next step of crushing cannot be influenced.
