In developing this invention, the inventors discovered at least the following unresolved problems in the existing technology: While separating metals and non-metals reduces resource waste and collects generated dust, thus reducing the health threat to construction workers, the traditional tilted separation box causes the pulverized construction waste to slide downwards quickly and accumulate within the box, preventing the separation of metal waste and affecting the effectiveness of metal-non-metal separation. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example 1: An environmentally friendly civil engineering construction waste treatment device, see [link to example]. Figures 1 to 3 The machine includes a frame 1, with two conveying rollers 11 rotatably connected to the inner side of the frame 1, and a conveyor belt 12 between the two conveying rollers 11. A connecting frame 2 is installed on the frame 1, and annular baffles 21 are fitted on both outer sides of the conveyor belt 12. The annular baffles 21 are connected to the frame 1 through the connecting frame 2, and a crushing mechanism is installed on one side of the top of the annular baffles 21. A fixed plate 3 is installed on the top side of the annular baffle 21 away from the crushing mechanism. A drive roller 31 is rotatably connected between the two fixed plates 3. A separation belt 33 is provided between the two drive rollers 31, and there is a gap between the separation belt 33 and the annular baffle 21. An electromagnet 34 is installed between the two fixed plates 3. A first drive motor 32 is installed at one end of the outer side of the fixed plate 3. The drive end of the first drive motor 32 is connected to the drive roller 31. An mounting plate 4 is installed on the annular baffle 21 between the fixed plate 3 and the crushing mechanism. A uniform distribution roller 41 is rotatably connected to the mounting plate 4. A separation belt 33 is installed on the outer side of the uniform distribution roller 41. Multiple evenly distributed rods 42 are provided, and the evenly distributed rods 42 are in contact with the surface of the conveyor belt 12. A transmission mechanism is provided between the evenly distributed roller 41 and the drive roller 31. The transmission mechanism includes a first bevel gear 72 mounted on the evenly distributed roller 41 and a drive shaft 7 mounted on one end of the drive roller 31. A second bevel gear 71 is mounted on the end of the drive shaft 7 near the first bevel gear 72. The first bevel gear 72 and the second bevel gear 71 mesh. During operation, the construction waste is crushed by the crushing mechanism. The crushed particles are conveyed to the horizontal conveyor belt 12. The conveyor roller 11 inside the frame 1 is driven by the motor. The conveyor belt 12 runs at a constant speed, while the annular baffles 21 on both sides act as lateral limiters to prevent material spillage and ensure stable transport along the central axis. When the material reaches below the mounting plate 4, the first drive motor 32 starts, driving the distribution roller 41 to rotate via the drive roller 31, transmission shaft 7, and bevel gear (the second bevel gear 71 meshes with the first bevel gear 72 on the distribution roller 41). The outer distribution rod 42 contacts the surface of the conveyor belt 12, breaking up and flattening the unevenly piled material. The evenly distributed material then enters the electromagnetic separation area, where the electromagnets 34 between the fixed plates 3 are energized to generate a stable... A fixed magnetic field adsorbs waste metals from the material. Simultaneously, the first drive motor 32 drives the separation belt 33 to run. When the metal particles leave the magnetic field range with the separation belt 33, they fall off the surface of the separation belt 33 under the action of inertia. Due to the reserved gap between the separation belt 33 and the annular baffle 21, the metal particles are discharged from the gap between the separation belt 33 and the annular baffle 21 due to inertia and are finally collected in the collection box (not shown) on one side of the rotation direction of the separation belt 33. The non-metallic material continues to be transported to the corresponding collection area with the conveyor belt 12, further improving the separation effect of waste metals and non-metals.

[0014] For details, see Figure 1 and Figure 2The crushing mechanism includes a crushing box 5 mounted on an annular baffle 21. Both the upper and lower ends of the crushing box 5 are open. Two crushing rollers 54 are rotatably connected to the inner cavity of the crushing box 5. A second drive motor 51 is mounted on one of the outer ends of the crushing box 5. The drive end of the second drive motor 51 is connected to one of the crushing rollers 54. Two drive gears 53 are mounted on the end of the crushing box 5 away from the second drive end. The two drive gears 53 are connected to the two crushing rollers 54 respectively through connecting shafts, and the two drive gears 53 mesh with each other. By starting the second drive motor 51, the crushing rollers 54 are driven to rotate, thereby driving the drive gears 53 to rotate. In turn, the two meshing drive gears 53 can drive the two crushing rollers 54 to rotate synchronously in opposite directions to crush the construction waste.

[0015] Further, see Figure 1 A limiting plate 52 is installed on one side of the bottom of the crushing box 5. The bottom of the limiting plate 52 is fitted to the conveyor belt 12. The limiting plate 52 can shield the crushed construction waste, thereby preventing the crushed construction waste from falling from one side of the conveyor belt 12 and affecting the separation of construction waste.

[0016] It is worth noting that, see Figure 1 and Figure 2 A dust suction plate 62 is installed on one side of the top opening of the shredder 5. The dust suction plate 62 has a hollow structure. Multiple dust suction ports 63 are opened at one end of the dust suction plate 62. The end of the dust suction plate 62 away from the dust suction ports 63 is connected to a dust suction pipe 61. The other end of the dust suction pipe 61 is connected to a negative pressure collection box 6. When shredding construction waste, a negative pressure pump (not shown) on the negative pressure collection box 6 generates negative pressure inside the negative pressure collection box 6. The dust suction ports 63, dust suction plate 62, filter screen (installed inside the negative pressure collection box 6, not shown) and dust suction pipe 61 are used to collect the dust generated by shredding, so as to avoid dust from causing harm to personnel.

[0017] It is worth noting that, see Figure 1 A connecting rod 8 is installed on the frame 1, and a support plate 81 is installed on the connecting rod 8. The support plate 81 is placed inside the conveyor belt 12, and the surface of the support plate 81 is in contact with the conveyor belt 12. By setting the support plate 81, the conveyor belt 12 can be supported, thereby improving the contact effect between the conveyor belt 12 and the annular baffle 21, and preventing the crushed waste from getting stuck between the annular baffle 21 and the conveyor belt 12 or falling from the annular baffle 21 and the conveyor belt 12, which would affect the separation of construction waste.
