It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

The terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.

[0021] Construction waste refers to the slag, abandoned soil, abandoned materials, residual mud and other waste generated during the construction, laying, demolition and repair of various buildings, structures, pipelines, etc. by construction units or individuals.

[0022] In the existing technology, construction waste is first crushed by a crushing device and then sorted by a sorting device. The sorting device usually uses a magnet to adsorb and separate the ferrous metal in the construction waste, completing the separation of ferrous resources and the recycling of ferrous metals. However, there will still be ferrous metal residues after separation, and the separation is not complete, which reduces the separation effect.

[0023] See also Figures 1 to 5 The construction waste sorting device provided by the present invention is now described. The construction waste sorting device comprises a frame 10, a conveying assembly 20, two adsorbing members 30, and a toggle assembly 40. The conveying assembly 20 is horizontally mounted on the frame 10 and is used to transport construction waste. The two adsorbing members 30 are mounted on the top of the frame 10 and above the conveying assembly 20 and are used to adsorb ferrous metals. The two adsorbing members 30 are spaced apart horizontally. The toggle assembly 40 is rotatably connected to the top of the frame 10 and is located between the two adsorbing members 30. The toggle assembly 40 extends downward and is used to rotate and toggle the construction waste.

[0024] Furthermore, the adsorption member 30 is an electromagnet.

[0025] The present embodiment provides a construction waste sorting device. During actual use, the core function of the toggle assembly 40 is to actively disturb construction waste. Construction waste is often piled with or wrapped with ferrous metal. Relying solely on magnets to attract surface metals is limited in efficiency. The downwardly extending and rotating toggle blades 44 effectively break up the waste pile, stir the underlying material, and peel away the wrapping, exposing deeply buried or covered ferrous metal. This significantly improves the adsorption efficiency of the adsorption element 30 for hidden metals.

[0026] The conveying component 20 transports the construction waste, the two adsorption components 30 provide a strong covering adsorption force, and the toggle component 40 performs the key loosening and exposure of the construction waste in the middle. The three work together to achieve efficient separation of ferrous metals in the construction waste.

[0027] First, the construction waste is placed on the conveying component 20 for conveying. When the construction waste reaches the bottom of the first adsorption component 30, the adsorption component 30 adsorbs the ferrous metal in the construction waste. The construction waste is then rotated and toggled by the toggle component 40, exposing the ferrous metal below. After passing through another adsorption component 30, the adsorption component 30 adsorbs the remaining ferrous metal. The separated construction waste is released at the output end of the conveying component 20, and then the adsorption of the ferrous metal by the adsorption component 30 is released, causing it to fall on the conveying component 20 and be transported to the output end by the conveying component 20. The output end of the conveying component 20 is provided with a receiving box for receiving construction waste and ferrous metal respectively, thereby achieving a complete separation of ferrous metal and construction waste and improving the separation effect.

[0028] Compared with the prior art, the construction waste classification device provided by this embodiment first places the construction waste on the conveying component 20 for conveyance. When the construction waste reaches the bottom of the first adsorption component 30, the adsorption component 30 adsorbs the ferrous metal in the construction waste. The construction waste is then rotated and toggled by the toggle component 40, exposing the ferrous metal below. After passing through another adsorption component 30, the adsorption component 30 adsorbs the remaining ferrous metal. The separated construction waste is released at the output end of the conveying component 20, and then the adsorption of the ferrous metal by the adsorption component 30 is released, causing it to fall on the conveying component 20 and be transported to the output end by the conveying component 20. A receiving box for receiving construction waste and ferrous metal respectively is placed at the output end of the conveying component 20, thereby achieving a complete separation of ferrous metal and construction waste and improving the separation effect.

[0029] In a possible implementation, the toggle assembly 40 is configured as follows: Figure 1 and Figure 4 The structure shown, see Figure 1 and Figure 4The toggle assembly 40 includes a drive shaft 41, a rotating shaft 43 and a toggle blade. The drive shaft 41 is rotatably connected to the top of the frame 10 and extends downward. The upper end of the drive shaft 41 is connected to a rotating drive member 42; the rotating shaft 43 is detachably connected to the lower end of the drive shaft 41 and extends downward; the toggle blade 44 is connected to the outer peripheral wall of the rotating shaft 43 and extends outward.

[0030] Specifically, the drive shaft 41 and the rotary drive member 42 provide a stable and reliable source of rotational power, ensuring that the moving blades 44 continue to work effectively.

[0031] The rotating shaft 43 is detachably connected to the drive shaft 41. The shifting blades 44 and their rotating shaft 43 are components that come into direct contact with trash, are subject to wear, impact, and even the risk of entanglement, and are therefore extremely susceptible to damage. This detachable connection allows the entire worn component (rotating shaft 43 + shifting blade 44) to be quickly and easily removed from the drive shaft 41 for replacement or repair if a blade deforms, breaks, or requires replacement or maintenance. This significantly reduces downtime for maintenance and improves equipment availability and efficiency, eliminating the need to disassemble the entire drive system or complex repairs.

[0032] Furthermore, a plurality of the shifting blades 44 are provided at intervals in the circumferential direction of the rotating shaft 43 , and a plurality of groups of the shifting blades 44 are provided at intervals in the vertical direction.

[0033] The radial blades 44 extend outward from the outer wall of the rotating shaft 43. This radial blade design provides a larger contact area and range for stirring, effectively stirring, lifting, and pushing the garbage material, ensuring that the garbage is fully turned over. The outward extension structure enhances its ability to break up and push the material.

[0034] In some embodiments, see Figure 4 The upper end of the rotating shaft 43 is connected to a mounting seat 50, and both sides of the mounting seat 50 have extension plates 51 extending outward. The lower end of the driving shaft 41 is connected to a hook seat 60, and the bottom of the hook seat 60 has two upwardly bent hook portions 61 for hooking the two extension plates 51 respectively.

[0035] Specifically, the mounting base 50 and the extension plate 51 provide a sturdy connection platform with a horizontal extension plate 51 at the upper end of the vulnerable rotating shaft 43 component.

[0036] The design of the hook seat 60 and hook portion 61 allows the shaft 43 assembly to be connected to the drive shaft 41 with a simple "hooking" action. The two upwardly curved hook portions 61 precisely hook onto the extension plates 51 on either side of the mounting seat 50. This design is extremely convenient for installation: simply align the extension plates 51 below the hook portions 61, lift the shaft 43 assembly upward, and allow the hook portions 61 to hook onto the extension plates 51. This operation is simple and quick, and generally requires no tools.

[0037] When disassembly is required, the rotating shaft 43 assembly mounting base 50 only needs to be pulled upward and outward to separate the extension plate 51 from the hook portion 61 .

[0038] Under normal working conditions, the gravity of the mounting base 50 will naturally press the extension plate 51 tightly against the hook portion 61, forming a stable connection to resist vibration during operation of the device.

[0039] In some embodiments, see Figure 4 A locking cavity 52 is horizontally provided on the mounting seat 50, and a locking piece 53 is provided on the inner top wall of the locking cavity 52 and upwardly penetrates the mounting seat 50. The locking piece 53 is threadedly connected to the mounting seat 50 and is used to rotate upward to hook the hanging seat 60.

[0040] Specifically, the locking member 53 (such as a tightening bolt) is screwed into the inner top wall of the locking cavity 52 , passes through the mounting seat 50 , and the upper end is tightened on the hook seat 60 .

[0041] When the locking member 53 is rotated upward, its upper end will press against the hook seat 60. Continuing to tighten will generate a downward thrust, firmly pressing the mounting seat 50 downward against the hook portion 61, so that the contact surface of the extension plate 51 and the hook portion 61 generates a strong positive pressure.

[0042] This locking method completely eliminates the risk of loosening, shaking, or even accidental unhooking of the mounting base 50 under severe vibration or shock loads. It significantly enhances the rigidity and stability of the connection, ensuring reliable operation of the toggle assembly 40 even under high-intensity conditions. Furthermore, unlocking (reverse rotation of the locking member 53) remains simple, preserving the convenience of the hook connection.

[0043] In a possible implementation, the rack 10 is configured as follows: Figure 1 and Figure 3 The structure shown, see Figure 1 and Figure 3 The top of the frame 10 is provided with two first telescopic members 31 extending downward and corresponding to the two adsorption members 30 one by one, and the lower ends of the first telescopic members 31 are connected to the adsorption members 30.

[0044] Specifically, to adapt to different thicknesses of construction waste, when processing a thicker layer of waste, the height of the adsorption member 30 can be lowered to enhance its adsorption force on the underlying metal. When it is necessary to avoid collision between the adsorption member 30 and the construction waste, the adsorption member 30 can be raised.

[0045] The height of the adsorption element 30 from the surface of the construction waste directly affects its adsorption force (magnetic force decreases sharply with increasing distance). By adjusting the height, the adsorption efficiency can be improved for different types and sizes of ferrous metals, avoiding excessive adsorption of non-ferrous impurities.

[0046] When the adsorption member 30 needs to be maintained, the adsorption member 30 can be raised to provide a safer and more convenient operating space.

[0047] When the equipment is started or stopped, the adsorption member 30 can be quickly lifted to prevent damage.

[0048] In a possible implementation, the transmission component 20 is configured as follows: Figure 3 and Figure 5 The structure shown, see Figure 3 and Figure 5 A conveyor belt 21 is provided on the conveying assembly 20, and a scraper 70 is provided on the frame 10 and is located below the conveyor belt 21. The scraper 70 includes an upper top piece 71 and a flexible wiper 72. The upper top piece 71 is provided at the bottom of the frame 10 and extends upward; the flexible wiper 72 is provided at the upper end of the upper top piece 71 and is used to scrape the conveyor belt 21.

[0049] Specifically, the scraping member 70 is located below the conveyor belt 21 , and the position is cleverly designed so that the return section (lower surface) of the conveyor belt 21 is used for cleaning.

[0050] The upper push piece 71 pushes the flexible wiper 72 upward so that it fits tightly against the lower surface of the conveyor belt 21 .

[0051] The flexible wiper 72 effectively removes dirt, debris, metal residue, and other debris adhering to the conveyor belt 21, preventing the accumulation of construction waste that could cause the conveyor belt 21 to deviate or slip. Furthermore, its flexible material prevents excessive wear and tear on the surface of the conveyor belt 21, thereby extending the service life of the conveyor belt 21. Keeping the conveyor belt 21 clean is crucial for maintaining the equipment's processing efficiency, reducing the burden on subsequent sorting units, and ensuring sorting purity.

[0052] In some embodiments, see Figure 3 and Figure 5 The upper push member 71 includes a accommodating tube 711, a telescopic rod 712 and an elastic member 713. The accommodating tube 711 is arranged at the bottom of the frame 10 and extends upward. The accommodating tube 711 has an upward opening; the telescopic rod 712 is slidably connected to the accommodating tube 711, and the flexible wiper 72 is connected to the upper end of the telescopic rod 712; the elastic member 713 is arranged in the accommodating tube 711, and the lower end of the elastic member 713 is connected to the inner circumferential wall of the accommodating tube 711, and the upper end is connected to the lower end of the telescopic rod 712, which is used to elastically push the telescopic rod 712 upward.

[0053] Specifically, the elastic member 713 continuously pushes upward against the telescopic rod 712 and the flexible wiper 72, ensuring that the flexible wiper 72 maintains appropriate, constant contact pressure with the lower surface of the conveyor belt 21. Even if the conveyor belt 21 has uneven thickness, uneven joints, or slight oscillations or vibrations, the flexible wiper 72 automatically adapts, maintaining an effective fit and providing consistent cleaning results, avoiding incomplete cleaning due to insufficient pressure or excessive wear due to excessive pressure.

[0054] The elastic member 713 can absorb vibration and impact of the conveyor belt 21 during operation, and protect the scraping member 70 itself and the conveyor belt 21 from damage caused by hard impact.

[0055] As the flexible wiper 72 wears out, the elastic member 713 can automatically compensate and push the telescopic rod 712 upward, thereby maintaining effective contact and extending the effective service life of the scraper 70.

[0056] Furthermore, a flexible bellows 73 is sleeved on the outer periphery of the telescopic rod 712 , the upper end of the flexible bellows 73 is connected to the flexible wiper 72 , and the lower end is connected to the upper end surface of the accommodating tube 711 .

[0057] In some embodiments, see Figure 5 An electromagnet 714 for adsorbing the telescopic rod 712 is provided on the inner bottom wall of the accommodating cylinder 711. The electromagnet 714 can repeatedly adsorb the telescopic rod 712 so that the flexible wiper 72 repeatedly hits the conveyor belt 21.

[0058] Specifically, the electromagnet 714 (disposed on the inner bottom wall of the accommodating tube 711 ) can be controlled to be on and off.

[0059] When the electromagnet 714 is energized, it will absorb (pull downward) the lower end of the telescopic rod 712 and compress the elastic member 713; when the electromagnet 714 is de-energized, the elastic member 713 is quickly released, causing the telescopic rod 712 (together with the flexible wiper 72) to rebound upward and hit the conveyor belt 21.

[0060] This high-frequency beating action can produce strong vibration and impact force, specifically targeting those hard-to-remove, hardened soil, goo or small debris embedded in the texture of the conveyor belt 21 that are difficult to remove by simply scraping with the flexible wipe 72. The vibration helps to loosen the adhesion, and the impact force peels it off.

[0061] The deep cleaning effect of the conveyor belt 21 is significantly improved, especially when processing construction waste with high humidity and strong viscosity, to prevent the accumulation of materials to form lumps.

[0062] The intensity and frequency of the impact can be adjusted by controlling the on-off frequency and duration of the electromagnet 714 to meet different cleaning needs.

[0063] In a possible implementation, the rack 10 is configured as follows: Figures 1 to 3The structure shown, see Figures 1 to 3 A first collecting box 80 for collecting construction waste and a second collecting box 81 for collecting ferrous metal are provided at the bottom of the frame 10. The first collecting box 80 is located on the inner side of the second collecting box 81 and is both arranged close to the output end of the conveying assembly 20. A guide box 90 for guiding ferrous metal is rotatably connected to the frame 10. The guide box 90 can swing vertically to block the top of the first collecting box 80 and overlap the frame 10 to guide the ferrous metal into the second collecting box 81.

[0064] Specifically, after the adsorption member 30 adsorbs the metal, the guide box 90 is in a retracted state (such as vertical or slightly inclined), and the non-iron garbage directly falls into or slides into the first collection box 80.

[0065] Then when the adsorption member 30 releases the ferrous metal and moves to the output end with the conveyor belt 21, the guide box 90 swings vertically to overlap the frame 10 to form a slide, and is located below the output end of the conveyor belt 21, in an inclined position, blocking the top of the first collection box 80.

[0066] The fallen ferrous metal falls on the slideway formed by the guide box 90 and is guided along the slideway to slide into the second collection box 81 outside. At the same time, the guide box 90 blocks the first collection box 80 to prevent the ferrous metal from accidentally falling therein.

[0067] This design achieves physical separation of the two materials at the collection point, ensuring the purity of the sorting and avoiding the trouble of manual re-sorting of mixed collections. The structure is relatively simple and reliable, with a high degree of automation.

[0068] In some embodiments, see Figures 1 to 3 The guide box 90 is rotatably connected to the frame 10 through a swing shaft 91. The end of the swing shaft 91 is connected to a swing plate 92. A second telescopic member 93 is provided between the swing plate 92 and the frame 10. The two ends of the second telescopic member 93 are respectively hinged to the swing plate 92 and the frame 10, and are used to drive the swing plate 92 to swing vertically.

[0069] Specifically, by controlling the extension and contraction of the second telescopic member 93, the swing plate 92 (and thus the guide box 90) can be accurately and reliably driven to swing vertically between two predetermined positions (blocking and diverting position and non-blocking position), with a stable motion trajectory.

[0070] The second telescopic member 93 (particularly a pneumatic / hydraulic cylinder) provides sufficient driving force to ensure that the guide box 90 can stably move into position and maintain its position even under loads (such as falling metal). The hinged connection can withstand certain shocks and loads and is suitable for industrial environments.

[0071] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
