These metal wastes are sometimes tightly combined with concrete blocks to form construction waste that is difficult to recycle. These metal wastes have good reuse value. If they are not effectively recycled, it will cause a waste of resources. Traditional construction waste recycling and reuse devices crush the waste, separate the metals in the waste, and then use the non-metallic waste for road construction. However, traditional construction waste recycling and reuse devices are difficult to effectively recycle relatively small metal waste. It is easy to cause incomplete recycling of metal waste.

The spiral material guide mechanism 4 includes a roller shaft 41, which passes through the receiving bin 3 and is rotatably connected to the receiving bin 3. The roller shaft 41 is located outside the part where the receiving bin 3 is located.

Two rotationally symmetrical swing arms 64 are arranged on the circumferential surface of the fixing ring 63. The swing arm 64 includes a metal inner arm 641, and a hard plastic 642 is fixedly sleeved on the outside of the metal inner arm 641. One end of the metal inner arm 641 is fixed to the fixing ring 63. The other end of the metal inner arm 641 is fixedly connected with a soft rubber sleeve 643, and the soft rubber sleeve 643 is an arc-shaped bend. The driving motor 5 can drive the driving shaft 61 to rotate, and the driving shaft 61 drives the driving gear 62 to rotate, and the roller shaft 41 is driven to rotate through the meshing of the driving gear 62 and the driven gear 43, and then the waste is gradually pushed toward the material guide port 33 through the magnetic spiral sleeves 42 on the two roller shafts 41. The rotation of the driving shaft 61 can drive the fixed ring 63 and the swing arm 64 on the fixed ring 63 to rotate. Since the rotation path of the swing arm 64 covers the material guide port 33 and passes through the scraper 44, as shown in FIG. Figure 4 As shown, the soft rubber sleeve 643 of the swing arm 64 first scrapes off the small pieces of metal waste at the guide port 33 during the clockwise rotation, and then rotates through the scraper blade 44. On the one hand, the rotating scraper blade 44 can help the inertia moment generated by the rotation to break up the scraped small pieces of metal waste, and on the other hand, it can help the flexible characteristics of the soft rubber sleeve 643 to scrape off the metal waste attached to the soft rubber sleeve 643.

[0033] See also Figure 2 , Figure 8 and Fig. 9 The material distribution mechanism 7 includes a roller 71, which is rotatably arranged in the lower discharge port 14. The roller 71 is truncated and the drum body is provided with a plurality of material holes 74 which are perpendicular to the axis of the roller 71. The small end of the roller 71 passes through the second material collection area 13. A shaft rod 72 is arranged at the center of the roller 71. A first fixed bracket 73 which is fixedly connected to the shaft rod 72 is fixed in the large end of the roller 71, and a second fixed bracket 75 which is fixedly connected to the shaft rod 72 is fixed in the small end of the roller 71.

[0034] See also Figure 2 The guide trough 9 is tiltedly arranged below the receiving bin 3 , and gradually closes from top to bottom to the small end of the drum 71 . The small pieces of metal waste scraped off by the two guide ports 33 are concentrated and guided into the drum 71 through the guide trough 9 .

[0035] See also Figure 8 and Fig. 9 The transmission mechanism 8 includes a driving sprocket 81, which is fixed outside the driving shaft 61. One end of the shaft rod 72 is rotatably connected to the inner wall of the bin body 1. The other end of the shaft rod 72 extends outside the bin body 1 and is fixed with a driven sprocket 82. The driven sprocket 82 is transmission-connected to the driving sprocket 81 through a chain 83. When the driving motor 5 drives the driving shaft 61 to rotate, the driving sprocket 81 can be driven to rotate. Under the transmission action of the chain 83, the driven sprocket 82 can be driven to rotate. Then, the shaft rod 72 and the first fixed bracket 73 and the second fixed bracket 75 at both ends of the shaft rod 72 drive the roller 71 to rotate continuously. Since the roller 71 is a truncated cone, small pieces of metal waste can continuously move from the small head end of the roller 71 to the large head end. In this process, the material holes 74 on the roller 71 are further sorted, so that the metal waste with smaller particles falls into the second collection area 13 for collection, while the metal waste with larger particles is discharged from the lower discharge port 14 through the large head end of the roller 71.

[0036] The working principle and use process of the present invention are as follows: road debris and construction waste enter the bin body 1 through the feed port 11, are crushed by the crushing mechanism 10, and fall onto the screen of the screening mechanism 2. The large pieces of metal and non-metal waste are discharged through the upper discharge port 15 under the vibration of the screen of the screening mechanism 2, while small pieces of metal and non-metal waste pass through the screen of the screening mechanism 2 and fall into the receiving bin 3;

[0037] The driving motor 5 can drive the driving shaft 61 to rotate, and the driving shaft 61 drives the driving gear 62 to rotate, and the roller shaft 41 is driven to rotate through the meshing of the driving gear 62 and the driven gear 43, and then the waste is gradually pushed toward the material guide port 33 through the magnetic spiral sleeves 42 on the two roller shafts 41. In this process, small pieces of non-metallic waste fall through the screen 32 at the bottom of the receiving bin 3 and are collected by the first collecting area 12, while small pieces of metal waste are pushed to the material guide port 33 through the magnetic attraction of the magnetic spiral sleeve 42. The rotation of the driving shaft 61 can drive the fixed ring 63 and the swing arm 64 on the fixed ring 63 to rotate. Since the rotation path of the swing arm 64 covers the material guide port 33 and passes through the scraper 44, as shown in FIG. Figure 4 As shown, the soft rubber sleeve 643 of the swing arm 64 first scrapes off the small pieces of metal waste at the guide port 33 during the clockwise rotation process, and then rotates through the scraper blade 44. On the one hand, the rotating scraper blade 44 can help the inertia moment generated by the rotation to break up the scraped small pieces of metal waste, and on the other hand, it can help the flexible characteristics of the soft rubber sleeve 643 to scrape off the metal waste attached to the soft rubber sleeve 643;

[0038] The small pieces of metal waste scraped off by the two guide ports 33 are concentrated and guided into the roller 71 through the guide groove 9, and the driving motor 5 drives the driving shaft 61 to rotate, while driving the driving sprocket 81 to rotate, and the driven sprocket 82 can be driven to rotate under the transmission action of the chain 83, and then the shaft 72 and the first fixed bracket 73 and the second fixed bracket 75 at both ends of the shaft 72 drive the roller 71 to rotate continuously. Since the roller 71 is a truncated cone, the small pieces of metal waste can continuously move from the small end to the large end of the roller 71, and then in this process, the material holes 74 on the roller 71 are further sorted, so that the metal waste with smaller particles falls into the second collection area 13 for collection, while the metal waste with larger particles is discharged out of the lower discharge port 14 through the large end of the roller 71.
