The lower end of support 141 is fixedly provided with arc retaining ring 142, which rotates with screening cylinder 1 32. The arc retaining ring 142 can block part of the through groove 1 323, so that construction waste will not fall from other places when screening cylinder 1 32 rotates. The lower surface of support plate 3 14 is symmetrically fixed with bracket 1 143, which is rotatably set between the two retaining rings 2 321. The bracket 1 143 is used to support screening cylinder 1 32.

[0035] refer to Figure 2-12 The sorting component 2 4 includes support 41 and support 5 42, which are symmetrically fixed on the upper surface of support plate 1 11. A worm gear 44 is arranged between support 41 and support 5 42. The worm gear 44 is used to convey small construction material waste that falls down.

The discharge frames 47 are connected to discharge cylinder 46 and are used for screening. For medium-sized construction material waste, a discharge port 432 is provided above the middle surface of frame 2 43. The discharge frame 47 and discharge cylinder 46 are connected to frame 2 43 through the discharge port 432. A discharge port 431 is provided on the lower left side surface of frame 2 43. The left end of frame 2 43 is fixedly engaged with support 5 42. A rotating body 45 is fixedly provided on the right side surface of worm gear 44.

A spring 4721 is fixedly mounted on the lower surface of the rod of the connector 472. The other end of the spring 4721 is fixedly mounted in the through groove 475. The connector 472 is in contact with the rotating wheel 48. A gear 461 is fixedly mounted on the left side of the discharge cylinder 46. The gear 461 is sleeved. On the outer surface of frame 43 without contact, a motor 421 is fixedly installed at the upper end of support 42. A gear 422 is fixedly installed on the surface of the output shaft of motor 421. Gear 461 and gear 422 mesh. The rotation of worm 44 drives the rotation of rotating body 45, which in turn drives the rotation of rotating wheel 48. Rotating wheel 48 pushes connecting piece 472 through several arc protrusions on its surface, which can shake the construction waste falling onto the surface of screening plate 471. When the material waste in discharge frame 47 is almost full, the drive gear 422 can be used to drive discharge cylinder 46 to rotate, so that the next discharge frame 47 is in a vertical state to collect construction materials.

[0037] refer to Figure 2-12A large building material collection frame 17 is fixedly installed on the left side of the upper surface of support plate 11. A medium-sized building material collection frame 15 and a small building material collection frame 16 are fixedly installed in the middle of the upper surface of support plate 11. The large building material collection frame 17 is directly opposite the second conveying pipe. A bracket 331 is fixedly installed on the lower outer surface of the second conveying pipe. The bracket 331 is fixedly fitted with the inner surface of the large building material collection frame 17. The medium-sized building material collection frame 15 is directly opposite the discharge frame 47. The small building material collection frame 16 is directly opposite the discharge port 432. A discharge frame 133 is fixedly installed on the upper surface of support plate 13, directly opposite the through groove 323. A telescopic cylinder 131 is fixedly installed on the lower surface of support plate 13. The piston rod of the telescopic cylinder 131... A T-shaped push plate 132 is fixedly installed at the outer end. The T-shaped push plate 132 can pass through the side of the feeding frame 133 and close it. When the discharge cylinder 46 rotates, the telescopic cylinder 131 starts to work and pushes the T-shaped push plate 132 into the feeding frame 133 to temporarily close it and prevent building materials from falling to other positions. The lower opening of the feeding frame 133 is directly opposite the vertical discharge frame 47. A motor 411 is fixedly installed on the upper surface of the support plate 11, which is directly opposite the support 41. A roller 4111 is fixedly installed on the surface of the output shaft of the motor 411. A transmission belt 412 is slidably installed on the surface of the roller 4111. A roller 441 is fixedly installed on the surface of the outer end of one side of the worm 44. The transmission belt 412 connects the roller 4111 and the roller 441.

[0038] Construction waste is transported via conveyor belt 21, then guided by guide plate 223 into frame 23. Driven by motor 232, the two rotating drums 235 are rotated. The construction waste transported from conveyor belt 21 is initially crushed and separated by the teeth 236 on the surface of the rotating drums 235. The waste then falls into conveyor pipe 31 through frame 23 and enters screening cylinder 32 through conveyor pipe 31.

[0039] Furthermore, starting motor 1411 drives gear 4 343 to rotate, which in turn drives the fixed shaft 341, connecting ring 1 34, and connecting ring 2 342 to rotate. Starting motor 2 1441 drives gear 3 322 to rotate, which in turn drives the screening cylinder 1 32 to rotate. The driving directions of motor 1 1411 and motor 2 1441 are opposite. There is a certain gap between the fixed shafts 341 on connecting ring 1 34, which allows medium and small construction waste to fall through the trough 1 323 into the lower feed frame 133, and then enter the discharge frame 47 from the feed frame 133. Then, starting motor 5 411 drives the worm gear 44 to rotate, which in turn drives the rotating body 45. The rotation of the rotating wheel 48 drives the rotating wheel 48 to rotate. The rotating wheel 48 pushes the connecting piece 472 through several arc protrusions on its surface, which can shake the construction waste that falls onto the surface of the screening plate 471. At this time, medium and small construction waste are screened. When the material waste in the discharge frame 47 is about to overflow, the drive gear 422 can be used to drive the discharge cylinder 46 to rotate. When the discharge cylinder 46 rotates, the telescopic cylinder 131 starts to work and pushes the push plate into the discharge frame 133 to temporarily close it and prevent the construction materials from falling to other positions. Then, the next discharge frame 47 is in a vertical state to collect the construction materials.

[0040] Furthermore, as the discharge cylinder 46 rotates, it will drive the discharge frame 47 to rotate, which will allow the screened medium-sized construction waste to enter the medium-sized construction material collection frame 15. Then, as the worm gear 44 rotates, it will drive the small construction waste from the discharge port 432 into the small construction material collection frame 16. At the same time, the upper screening cylinder 32 will transport the large construction waste through the conveying pipe 33 into the large construction material collection frame 17.
