[0027] Both sides of the lower end of the cabinet shell 1 are fixedly connected to fixed shaft frames 6, and a mounting shaft 7 is fixedly connected inside the fixed shaft frame 6. A magnetic block 17 is fixedly connected to the outer periphery of the mounting shaft 7. Rings 8 are rotatably sleeved on both ends of the mounting shaft 7, and a ring cover 16 is fixedly connected between the two rings 8. The ring cover 16 is arranged at the lower end of the crushing mechanism. The ring cover 16 cooperates with the magnetic block 17 to separate the metal in the crushed construction waste into non-metallic construction waste, and realizes the function of automatically classifying metal materials and non-metallic materials after crushing. There is no need for manual separation, which reduces manpower consumption and improves the separation efficiency of metal materials.

[0028] like Figure 1-4 As shown, the magnetic block 17 is an incomplete cylindrical block of 220°, and the mounting shaft 7 is non-centrally arranged to control the magnetic attraction range of the magnetic block 17 on the annular cover 16 .

[0029] like Figure 1-4 As shown, the crushing mechanism includes a crushing roller 14 fixedly mounted on the outer peripheral surface of the rotating shaft 12, and a gear 13 is fixedly connected to the same end of the two rotating shafts 12. The two gears 13 are meshed and driven to be connected. The gears 13 mesh with each other, so that the crushing roller 14 can realize the function of rolling crushing.

[0030] like Figure 1-4 As shown, a mounting frame 5 is fixedly connected to the cabinet housing 1 on the side away from the gear 13, and a drive motor 4 is fixedly installed in the mounting frame 5. The output end of the drive motor 4 is fixedly connected to any one of the rotating shafts 12. The mounting frame 5 is used to facilitate the installation of the drive motor 4, and the drive motor 4 serves as the power source of the device.

[0031] like Figure 1-4 As shown, a first pulley 10 is fixedly connected to the outer circumference of the other rotating shaft 12 away from the gear 13, and a second pulley 9 is fixedly sleeved on the outer circumference of the ring 8 close to one end of the rotating shaft 12. A belt 19 is sleeved between the second pulley 9 and the first pulley 10. Through the second pulley 9 and the first pulley 10, when the rotating shaft 12 rotates, the belt 19 cooperates with the first pulley 10 and the second pulley 9 to synchronously drive the ring 8 to rotate, thereby driving the ring cover 16 to rotate.

[0032] like Figure 1-4 As shown, the cabinet housing 1 is rotatably connected to one end of the rotating shaft 12 with a tension wheel 11, and the outer circumference of the tension wheel 11 abuts against the inner wall of the belt 19.

[0033] like Figure 1-4 As shown, two oppositely distributed guide plates 15 are fixedly connected inside the cabinet shell 1, and the guide plates 15 are located between the ring cover 16 and the crushing mechanism. The lower end of the gap between the two guide plates 15 is within the magnetic attraction range of the magnetic block 17.

When the rotating shaft 12 rotates, the two gears 13 cooperate with each other to synchronize the rotating shaft 12 on the other side, so as to control the two crushing rollers 14 to rotate in opposite directions. The two crushing rollers 14 rotate in opposite directions to realize the function of crushing the construction waste. After the construction waste is crushed, the waste falls on the upper end of the ring cover 16 through the two guide plates 15. When the rotating shaft 12 rotates, the belt 19 cooperates with the first pulley 10 and the second pulley 9 to synchronously drive the ring 8 to rotate, so as to drive the ring cover 16 to rotate. The cabinet housing 1 is provided with a tensioning wheel 11 to keep the belt 19 in a tight state to ensure that the belt 1 9 Stable operation, a magnetic block 17 is arranged in the ring cover 16, and the magnetic block 17 forms a magnetic attraction range, so that the metal material falling on the ring cover 16 is adsorbed on the upper end of the ring cover 16, and as the ring cover 16 rotates, the non-metallic waste will fall on one side of the conveyor belt 2 with the rotation of the ring cover 16 and be transported out of the device. Since the magnetic attraction range of the magnetic block 17 is fixed, the metal adsorbed on the ring cover 16 will be separated from the ring cover 16 when the ring cover 16 is rotated to a position with smaller magnetic attraction, and fall on the other side of the conveyor belt 2 through the separation effect of the partition plate 18 and be transported out, thereby realizing the function of automatically classifying and outputting metal materials and non-metallic materials after crushing, without manual separation, reducing manpower consumption and improving the separation efficiency of metal materials.
