[0002] Construction waste recycling equipment can process discarded concrete blocks, bricks and stones into recycled aggregates. Through crushing and screening equipment, the concrete blocks in construction waste can be broken into particles of different sizes. These recycled aggregates can replace natural aggregates for concrete production in construction projects.

[0007] As a further solution of the present invention: a hydraulic rod is installed on the top of the arc frame, a sliding plate is slidably connected to the head end and the tail end of the outer side of the arc frame, the bottom of the sliding plate is fixedly connected to the inside of the crushing box, and a fixed slider is rotatably connected to the middle part of the bottom of the annular fixed frame.

[0008] As a further solution of the present invention: connecting frames are connected to both sides of the fixed slider, and the gear rod is engaged with the tooth groove to rotate the gear rod, and the gear rod drives the elliptical crushing roller to rotate to hammer the concrete column back and forth to smash the concrete column. The top of the connecting frame is fixedly connected to the top of the inside of the crushing box, and fixed plates are fixed at both ends of the fixed slider.

[0009] As a further solution of the present invention: the gear rod is meshed with the tooth groove, the sliding block penetrates to the outside of the annular fixed frame, and the hydraulic rod is controlled to push the arc frame to move upward, thereby adjusting the height of the arc frame, and the arc plate and the sliding block are driven to rotate left and right by the left and right rotation of the annular fixed frame.

[0033] In this embodiment: the No. 2 gear 401 drives the No. 1 crushing roller 402 to crush the outer side of the concrete column once, and the concrete column falls into the annular fixing frame 201. The No. 1 crushing rollers 402 on both sides respectively drive the toothed ring plates 3 at both ends to rotate in opposite directions through the No. 2 chain 403. The toothed ring plates 3 drive the semi-ring tooth grooves 301 and the semi-ring tooth gears 302 to rotate. The toothed ring plates 3 drive the semi-ring tooth grooves 301 to rotate. When the semi-ring tooth grooves 301 rotate to the 1 / 6 position, the semi-ring tooth grooves 301 will drive the No. 1 gear 303 to rotate forward. When the semi-ring tooth grooves 301 rotate to the 3 / 6 position, the semi-ring tooth gears 302 will rotate forward. The groove 301 stops meshing with the No. 1 gear 303.

[0034] Working principle: The concrete column is put into the feed port 103 through the conveyor belt 101, and the No. 2 motor 4 is started to drive the No. 2 gear 401 to rotate. The No. 2 gear 401 drives the No. 1 crushing roller 402 to crush the outer side of the concrete column once, and the concrete column falls into the annular fixed frame 201. The No. 1 crushing rollers 402 on both sides respectively drive the toothed ring plates 3 at both ends to rotate in opposite directions through the No. 2 chain 403. The toothed ring plates 3 drive the semi-ring tooth grooves 301 and the semi-ring tooth gears 302 to rotate. The toothed ring plates 3 drive the semi-ring tooth grooves 301 to rotate. When the semi-ring tooth grooves 301 rotate to the 1 / 6 position, the semi-ring tooth grooves 301 will drive the No. 1 gear 303 to rotate forward, and the semi-ring tooth grooves 301 will rotate forward. When the tooth groove 301 rotates to the position of 3 / 6, the semi-ring tooth groove 301 stops meshing with the No. 1 gear 303. When the semi-ring tooth gear 302 rotates to the position of 4 / 6, the semi-ring tooth gear 302 meshes with the No. 1 gear 303 and drives the No. 1 gear 303 to reverse. When the semi-ring tooth gear 302 rotates to the position of 6 / 6, the semi-ring tooth gear 302 stops meshing with the No. 1 gear 303, thereby driving the circular plate 2 to rotate forward and reversely. The two circular plates 2 drive the annular fixing frame 201 to perform opposite left and right movements, twisting the internal concrete column, and crushing the relative displacement deformation of the cross section of the concrete column material along the direction of the external force through shear force;

[0035] The hydraulic rod 205 is controlled to push the arc frame 206 to move upward, thereby adjusting the height of the arc frame 206. The arc plate 209 and the sliding block 210 are driven to rotate left and right by the rotation of the annular fixing frame 201. The sliding block 210 is squeezed by the wedge-shaped slide groove 208. The wedges set in the wedge-shaped slide groove 208 have the same direction, so that the sliding block 210 moves toward the inside of the annular fixing frame 201. Then, the sliding block 210 pushes the arc plate 209 to squeeze the concrete column back and forth.

[0036] When the annular fixing frame 201 rotates left and right, the arc plate 209 drives the elliptical crushing roller 214 and the toothed rod 215 to rotate left and right. The toothed rod 215 meshes with the tooth groove 213 to rotate the toothed rod 215. The toothed rod 215 drives the elliptical crushing roller 214 to rotate and hammer the concrete column back and forth to break the concrete column. The No. 1 motor 104 is started to drive the No. 2 crushing roller 105 through the No. 1 chain 106 to perform more detailed crushing, and then discharge through the discharge port 102.
