[0002] Green building refers to buildings that, throughout their entire life cycle, maximize resource conservation, including energy, land, water, and materials, protect the environment and reduce pollution, provide people with healthy, comfortable, and efficient living spaces, and coexist harmoniously with nature.

[0003] A lot of construction waste is generated during the construction of green buildings. Construction waste refers to the slag, soil, waste materials, residual mud and other waste generated by construction units or individuals in the process of constructing, laying or demolishing and repairing various buildings, structures, pipelines, etc.

[0004] To recycle construction waste, the solid particles are typically crushed and then made into pressure bricks. However, construction waste often contains hard building materials such as steel bars and iron sheets that are worth recycling. If the construction waste is directly crushed, not only will the steel bars easily wear down the crushing blades, but the metal scrap cannot be effectively recycled, reducing the waste recycling rate. Utility Model Content

[0005] The purpose of this invention is to provide a waste sorting, screening and recycling device for green building construction, which can separate steel bars from soil and stones in construction waste, thereby improving the waste recycling rate of construction waste.

[0025] Example

[0026] The following description, in conjunction with specific embodiments, provides further details. Figures 1-4 As shown, this utility model is a waste sorting, screening, and recycling device for green building construction, referring to... Figure 1 and Figure 2 The device includes a main body 1, with a feed inlet 11 at the top. Construction waste enters the main body 1 through the feed inlet 11. Multiple baffle rods 12 are installed inside the main body 1, arranged vertically in a staggered pattern, with gaps between them to allow the construction waste to fall. As the construction waste falls into the main body 1 through the feed inlet 11, it impacts the baffle rods 12. The baffle rods 12 help separate the reinforcing steel sections from the soil during the impact.

[0027] Reference Figure 2 and Figure 3 The main body 1 of the device is internally equipped with multiple first screening rods 13 and second screening rods 14, located below the barrier rod 12. The multiple first screening rods 13 and second screening rods 14 are alternately distributed, with a screening gap 15 between them. The width of the screening gap 15 is greater than the diameter of the reinforcing bar segment, but less than twice the diameter of the reinforcing bar segment. The first screening rods 13 and second screening rods 14 are inclined vertically. A rotating rod 16 is horizontally arranged on the inner wall of the main body 1, with the lower ends of the first screening rods 13 and 14 rotatably connected to the rotating rod 16. The higher ends of the first screening rods 13 are interconnected via a first connecting rod. A first protrusion 131 is provided on the bottom surface of the first connecting rod. The top surface of the first screening rod 13 is provided with a first protruding tip 132, and the protruding end of the first protruding tip 132 is inclined toward the high end of the first screening rod 13.

[0028] Reference Figure 3 The higher ends of the second screening rod 14 are connected to each other via a second connecting rod. A second protrusion 141 is provided on the bottom surface of the second connecting rod. The first protrusion 131 and the second protrusion 141 are located on the same straight line. A second protruding tip 142 is provided on the top surface of the second screening rod 14, with the protruding end of the second protruding tip 142 inclined towards the higher end of the second screening rod 14. The first protruding tip 132 and the second protruding tip 142 are staggered, and the protrusion height of the first protruding tip 132 and the second protruding tip 142 is greater than the diameter of the reinforcing bar segment. When the construction waste slides along the inclined first screening rod 13 and second screening rod 14, the first protruding tip 132 and the second protruding tip 142 abut against the construction waste, which can both prevent the reinforcing bar segment within the construction waste from sliding and allow the reinforcing bar segment to fall below through the screening gap 15. At the same time, the first protruding tip 132 and the second protruding tip 142 can also tumble the sliding construction waste, accelerating the separation of soil and stone blocks from steel bars.

[0029] Reference Figure 2 and Figure 3 The main body 1 of the device is equipped with a drive motor 17. A first cam 171 and a second cam 172 are mounted on the output shaft of the drive motor 17. The protrusions in the first cam 171 and the second cam 172 have different phase angles relative to the output shaft of the drive motor 17. The first cam 171 abuts against a first protrusion 131, and the second cam 172 abuts against a second protrusion 141. The drive motor 17 drives the first cam 171 to rotate, causing it to lift the first screening rod 13 and rotate it around the rotating rod 16. The drive motor 17 also drives the second cam 172 to rotate, causing it to lift the second screening rod 14 and rotate it around the rotating rod 16. The alternating oscillation of the first screening rod 13 and the second screening rod 14 facilitates the passage of steel bars from the construction waste through the screening gap 15.

[0030] Reference Figure 2 The main body 1 of the device has a first outlet 18 located near the lower end of the first screening rod 13 and the second screening rod 14. A first collection box 19 is located below the first outlet 18 in the main body 1 of the device. Larger diameter soil and rock pieces that fail to pass through the screening gap 15 fall into the first collection box 19 through the first outlet 18 under the action of the oscillating first screening rod 13 and the second screening rod 14.

[0031] Reference Figure 2 and Figure 4Inside the main body 1 of the device, a screen 20 is installed at an angle. The first end of the screen 20 is close to the first outlet 18, and the second end is away from the first outlet 18. The height of the first end of the screen 20 is greater than the height of the second end. The diameter of the mesh openings on the surface of the screen 20 is smaller than the diameter of the reinforcing bar segment. Multiple limiting protrusions 201 are also raised on the top surface of the screen 20, evenly distributed on its surface, and their height is smaller than the diameter of the reinforcing bar segment. A vibration motor is installed inside the main body 1, and its output end is connected to the side of the screen 20. The vibration motor drives the screen 20 to vibrate, causing soil and rock fragments with a diameter smaller than the reinforcing bar segment to pass through the screen 20, thus separating the small-diameter fragments from the reinforcing bar segment.

[0032] Reference Figure 2 The device body 1 has a second outlet 21 on one side near the second end of the screen 20. A second collection box 22 is provided below the second outlet 21 in the device body 1. The second collection box 22 is used to collect the steel bar segments that slip from the screen 20.

[0033] Reference Figure 2 A flat plate 23 is fixedly installed inside the main body 1 of the device. The flat plate 23 is inclined. A third outlet 24 is opened on the bottom side of the main body 1 near the flat plate 23. The third outlet 24 is located on the same side as the first outlet 18 and is located above the first collection box 19. Small-diameter soil and rocks fall onto the flat plate 23 and slide down the inclined flat plate 23 through the third outlet 24 into the first collection box 19.

[0034] The working process of this embodiment is as follows: Construction waste enters the main body 1 of the device through the feed inlet 11. First, it is blocked by the barrier rod 12, causing the construction waste to tumble, which facilitates the separation of steel bars from soil and rocks. After the construction waste falls onto the top surface of the first screening rod 13 and the second screening rod 14, the drive motor 17 is started. The drive motor 17 controls the rotation of the first cam 171 and the second cam 172. The first cam 171 and the second cam 172 respectively drive the first screening rod 13 and the second screening rod 14 to tumble, causing the steel bars in the construction waste to fall through the screening gap 15 onto the top surface of the screen 20. Soil and rocks that cannot pass through the screening gap 15 fall into the first collection box 19 through the first outlet 18.

[0035] The vibration motor is started, causing the screen 20 to vibrate. This causes the steel bars and small-diameter soil and rocks that fall onto the screen 20 to slide along it. During this sliding process, the steel bars cannot pass through the mesh and can only fall into the second collection box 22 through the second outlet 21. The small-diameter soil and rocks pass through the mesh and fall along the plate 23 through the third outlet 24 into the first collection box 19, thus separating the steel bars and soil and rocks.

[0036] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
