Description

Technical Field

[0001] This utility model belongs to the field of construction waste recycling technology, specifically relating to a green building construction waste recycling device. Background Technology

[0002] Green building construction is a construction method that emphasizes resource conservation, environmental protection, and sustainable development. Under the premise of ensuring basic requirements such as quality and safety, it aims to achieve the goals of energy conservation, material conservation, water conservation, land conservation, and environmental protection through scientific management and technological progress. Green building construction generates construction waste, of which waste concrete, bricks, metals, and wood account for more than 80%. Through sorting, recycling, and reprocessing, these materials can be transformed into recycled aggregates, recycled bricks, and metal products, replacing natural resources and reducing dependence on non-renewable resources such as minerals and forests. The recycling of construction waste requires a crushing process, but some existing crushing devices often have certain shortcomings in use, so they need to be improved.

[0003] Chinese patent CN217856462U discloses a green building construction waste recycling device, including a crushing component. The crushing component comprises a crushing box, crushing rollers, a second motor, a fixing plate, rectangular holes, a limiting rod, a connecting plate, a spring, U-shaped holes, and a filter plate. Crushing rollers are rotatably installed between the inner walls of both sides of the crushing box. In this invention, small-particle construction waste enters the second collection box through the filter holes via a feeding pipe. Large-particle construction waste falls onto the filter plate. A first motor drives an eccentric wheel to rotate, which in turn moves the filter plate via a circular plate. The filter plate slides relative to the large-particle construction waste. Continuous operation of the first motor causes the filter plate to move cyclically left and right, gradually causing the large-particle construction waste to fall into the first collection box. The large-particle construction waste collected in the first collection box can be poured back into the crushing box for secondary crushing, which not only improves the recycling efficiency of construction waste but also avoids wasting a significant amount of human resources.

[0004] However, while the aforementioned technical solution can achieve the purpose of crushing and screening construction waste of different sizes, when screening out larger volumes of construction waste, the waste will accumulate inside the first collection box, requiring workers to move it and then dump it into the feed inlet for secondary crushing. If the amount of construction waste is large, workers need to move it frequently, which is physically demanding. At the same time, the crushed construction waste will accumulate inside the second collection box, which will require workers to remove it and move it to other locations later. The whole process is also quite laborious, undoubtedly increasing the workload and labor burden of the workers, and thus has certain limitations in its use. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1:

[0029] Please see Figures 1 to 8As shown, a green building construction waste recycling device includes a crushing box 1, a conveying chamber 2 fixedly connected to the surface of the crushing box 1, a slot at the bottom of one side of the crushing box 1, a conveyor belt 3 fixedly connected to the inner wall of the slot, a filter frame 4 fixedly connected to the bottom of the inner wall of the crushing box 1, a servo motor fixedly connected to the bottom of one side of the inner wall of the crushing box 1, an adjusting gear 5 fixedly connected to the output end of the servo motor, a baffle 6 meshing with the surface of the adjusting gear 5, through slots being provided inside both the crushing box 1 and the filter frame 4, and the surface of the baffle 6 sliding through the through slots, a vibration motor 7 fixedly connected to the top of one side of the filter frame 4, a filter plate 8 connected to one side of the bottom of the filter frame 4 via a hinge, a separator seat 9 fixedly connected to one side of the top of the filter plate 8, and blocking strips 10 fixedly connected to both sides of the filter plate 8, with a sliding groove 11 on one side of the blocking strip 10. A sliding rod is slidably connected inside the moving groove 11. A movable clamp is fixedly connected to the bottom of the other side of the inner wall of the crushing box 1. A hydraulic telescopic rod 12 is hinged to the surface of the movable clamp, and the output end of the hydraulic telescopic rod 12 is hinged to the surface of the sliding rod. A return port 13 is fixedly connected to the bottom of the other side of the inner wall of the crushing box 1. A protective shell is fixedly connected to the top of the conveying chamber 2. A first drive motor 14 is fixedly connected inside the protective shell. A spiral conveying auger 15 is fixedly connected to the output end of the first drive motor 14, and the spiral conveying auger 15 is located inside the conveying chamber 2. A connecting pipe 16 is fixedly and penetrates the top of one side of the conveying chamber 2. A guide chamber 17 is fixedly connected to one side of the top of the crushing box 1, and the surface of the connecting pipe 16 is fixed and penetrates the interior of the guide chamber 17. A feed inlet 18 is fixedly connected to the other side of the top of the crushing box 1, and one side of the guide chamber 17 communicates with the interior of the feed inlet 18.

[0030] The conveying chamber 2 allows the first drive motor 14 to rotate the screw conveyor 15, conveying larger particles of crushed waste. The conveyor belt 3 transports smaller particles of crushed waste that have passed through the filter plate 8. The filter frame 4 temporarily stores the crushed construction waste. The vibration motor 7 drives the filter frame 4 to vibrate. The filter plate 8 filters the smaller particles of crushed construction waste. The separator 9 blocks one side of the top of the filter plate 8. The separator 9 is inclined to facilitate the discharge of crushed construction waste onto the filter plate 8. The blocking strip 10 prevents... The crushed waste sliding on the filter plate 8 serves as a guide. The opening of the sliding groove 11 allows the sliding rod to slide inside it. The surface of the sliding rod is hinged to the output end of the hydraulic telescopic rod 12, which allows the filter plate 8 to rotate counterclockwise by a certain angle. This opens a certain gap at the bottom of the filter frame 4, facilitating the fall of larger crushed particles. Finally, the particles enter the return port 13 and are conveyed by the screw conveyor 15. The connection pipe 16 and the guide chamber 17 facilitate the entry of larger crushed construction waste into the feed port 18 for subsequent crushing.

[0031] An electric push rod 19 is fixedly connected to one side of the inner wall of the filter plate 8. A connecting short plate 20 is fixedly connected to the output end of the electric push rod 19, and the surface of the connecting short plate 20 penetrates the interior of the return port 13. The electric push rod 19 can drive the connecting short plate 20 to move to the left, thereby inserting it into the interior of the return port 13, ensuring that larger crushed construction waste can enter the interior of the return port 13. The return port 13 is connected to the interior of the conveying chamber 2, ensuring stable conveying of construction waste. The interior of the conveying chamber 2 has a circular vertical groove, which fits against the screw conveyor 15 to ensure stable conveying of construction waste.

[0032] A protective shell is fixedly connected to the top of one side of the crushing chamber 1. A second drive motor 21 is fixedly connected inside the protective shell. A transmission rod is fixedly connected to the output end of the second drive motor 21. A first gear 22 is fixedly connected to one side of the transmission rod, and a first crushing roller 23 is fixedly connected to the surface of the transmission rod. A crushing chamber is fixedly connected to the top of one side of the inner wall of the crushing chamber 1, and the first crushing roller 23 is located inside the crushing chamber. The second drive motor 21 provides a certain driving force for the rotation of the transmission rod, and the rotation of the transmission rod will drive the first gear 22 and the first crushing roller 23 to rotate.

[0033] A partition 24 is fixedly connected to one side of the inner wall of the crushing chamber 1. A second gear meshes with the surface of the first gear 22. A rotating rod 25 is fixedly connected inside the second gear, and the surface of the rotating rod 25 is rotatably disposed inside both the crushing chamber 1 and the partition 24. A second crushing roller is fixedly connected to the surface of the rotating rod 25. The partition 24 separates the first crushing roller 23 and the second crushing roller from the first gear 22 and the second gear, preventing jamming of the first gear 22 and the second gear. When the first gear 22 rotates, it drives the second gear to rotate, which in turn causes the rotating rod 25 to rotate, thereby causing the second crushing roller to rotate. The first crushing roller 23 and the second crushing roller mesh with each other when rotating, which facilitates the crushing of construction waste. The second crushing roller is also located inside the crushing chamber.

[0034] An inclined plate 26 is fixedly connected to the top of one side of the inner wall of the crushing chamber 1, and a trolley 27 is connected to the bottom of one side of the crushing chamber 1. A first recycling box 30 is connected to one side of the inner bottom wall of the trolley 27, and a second recycling box 31 is connected to the other side of the inner bottom wall of the trolley 27. The inclined plate 26 facilitates the guidance of the crushed construction waste into the interior of the filter frame 4. A material drop chute is provided at the bottom of the crushing chamber to facilitate the falling of the crushed construction waste. The trolley 27 facilitates the placement of the first recycling box 30 and the second recycling box 31 inside it.

[0035] A support plate 28 is fixedly connected to the bottom of the conveyor belt 3, and a baffle strip 29 is fixedly connected to the top of the support plate 28. Several electromagnets 38 are installed inside the conveyor belt 3. The first recycling bin 30 facilitates the collection of metal objects inside the construction waste, the baffle strip 29 facilitates the scraping of metal objects, and the electromagnets 38 facilitate the adsorption of metal objects in the crushed construction waste. Several electromagnets 38 are connected in series, and the number of electromagnets 38 is similar to the area of ​​the conveyor belt to ensure better adsorption of metal objects.

[0036] Two snap-fit ​​blocks 32 are fixedly connected to one side of the trolley 27. The snap-fit ​​blocks 32 have positioning grooves 33 inside. Two movable grooves are opened at the bottom of one side of the crushing box 1. The surface of the snap-fit ​​blocks 32 penetrates the interior of the movable grooves. A fixing block 34 is fixedly connected to the bottom of the inner side wall of the movable groove. A vertical rod 35 slides through the interior of the fixing block 34. A squeezing plate is fixedly connected to the bottom of the surface of the vertical rod 35. A compression spring 36 is fixedly connected to the top of the squeezing plate. The top of the compression spring 36 is fixedly connected to the bottom of the fixing block 34. A lifting rod 37 is fixedly connected to the middle of the surface of the vertical rod 35. The snap-fit ​​block 32 allows the positioning groove 33 to be opened, and the movable groove allows the snap-fit ​​block 32 to pass through its interior. The fixing block 34 allows the vertical rod 35 to slide inside its interior. The compression plate facilitates the upward compression of the bottom end of the compression spring 36, compressing it and causing the bottom end of the vertical rod 35 to move upward a certain distance, making it easier for the snap-fit ​​block 32 to enter the movable groove and create some space. After the compression spring 36 is reset, the bottom end of the vertical rod 35 can be inserted into the interior of the positioning groove 33, fixing the snap-fit ​​block 32 inside the movable groove. The lifting rod 37 makes it easy for the operator to lift the vertical rod 35 a certain distance.

[0037] A control panel is fixedly connected to the top of one side of the crushing box 1, and the control panel is electrically connected to the conveyor belt 3, servo motor, vibration motor 7, hydraulic telescopic rod 12, first drive motor 14, second drive motor 21, and electric push rod 19. Electromagnet 38 is electrically connected to the control panel.

[0038] The working principle of this utility model is as follows: The worker first pours the construction waste to be crushed into the feed inlet 18, which then enters the crushing chamber. At this time, the worker controls the second drive motor 21 to operate. The output of the second drive motor 21 drives the transmission rod to rotate, which in turn causes the first gear 22 and the first crushing roller 23 to rotate. The rotation of the first gear 22 drives the second gear to rotate, which in turn causes the rotating rod 25 to rotate. Subsequently, the second crushing roller rotates, meshing with each other to crush the construction waste. The crushed construction waste falls downwards through the chute and is guided into the filter frame 4 by the inclined plate 26. Simultaneously, the worker controls the vibration motor 7 to operate, which drives the filter frame 4 to vibrate. The movement causes the crushed construction waste to fall through the filter plate 8 and onto the conveyor belt 3. The operator can control the conveyor belt 3 to transport the crushed construction waste, which eventually enters the second recycling bin 31. Some larger pieces of construction waste cannot pass through the filter plate 8 and accumulate inside the filter frame 4. At this point, the operator controls the servo motor, whose output drives the adjusting gear 5 to rotate, causing the baffle 6 to slide continuously into the filter frame 4, blocking the falling construction waste. Simultaneously, the operator activates the hydraulic telescopic rod 12, the electric push rod 19, and the first drive motor 14. The output of the hydraulic telescopic rod 12, through its hinge with the sliding rod, opens the filter... As the filter plate 8 is pushed downwards, the sliding rod slides inside the sliding groove 11 to avoid interference caused by movement. This continues until the filter plate 8 rotates counterclockwise to open a certain angle. The electric push rod 19 then drives the connecting short plate 20 to insert into the return port 13. At this point, larger construction waste particles accumulated above the filter plate 8 slide downwards, passing through the connecting short plate 20 into the return port 13. The first drive motor 14 then operates, causing the screw conveyor 15 to rotate. This allows the larger construction waste particles entering the conveying chamber 2 through the return port 13 to be conveyed. They then pass through the conveying chamber 2 into the connecting pipe 16 and the guide chamber 17, finally entering the feed inlet 18 for further crushing. The waste then falls downwards through the filter plate 8. Construction waste containing metal objects will be attracted by electromagnet 38 and adhere to conveyor belt 3. When conveyor belt 3 rotates to the position of the baffle 29, the metal construction waste will be blocked. As more metal objects are blocked by the baffle 29, they will fall downwards into the first recycling bin 30. The construction waste falling downwards from the rotating end of conveyor belt 3 will fall into the second recycling bin 31. When a certain amount of metal objects and construction waste accumulates in the first and second recycling bins 30 and 31, the worker will lift the lifting rod 37. Then, the vertical rod 35 will drive the compression plate upwards, thereby compressing the compression spring 36. Subsequently, the bottom end of the vertical rod 35 will disengage from the positioning groove 33.Workers can then pull the cart 27 outwards to separate it from the crushing box 1, making it easier for them to transfer the metal objects and construction waste.
