[0002] Construction waste refers to all kinds of solid waste generated during various construction activities such as the construction, renovation, expansion, demolition, repair, and decoration of buildings and structures, as well as related site leveling, road construction, and other projects. Its main components include broken bricks, broken concrete blocks, waste mortar, waste stone, waste wood, waste metal (such as steel bars and iron wire), waste glass, waste plastics, waste ceramics, waste paint, and waste insulation materials.
[0003] Referring to prior art document 202221894102.9, a construction waste pretreatment and leveling device is disclosed. By setting up an electric motor to drive a gear system, which works in conjunction with a toothed belt to realize the reciprocating motion of the spreading plate, the construction waste is quickly leveled. By setting up a sorting mechanism, ferrous metal waste can be adsorbed and collected during the leveling process, saving time and labor costs.
[0004] The device provided in the aforementioned document has certain limitations in sorting and classifying construction waste. It cannot pick out lightweight waste such as waste plastics, which causes some trouble for subsequent waste classification work and increases the labor intensity of relevant processing personnel. At the same time, when pressing and spreading construction waste, it cannot smooth the surface of the waste, which increases the difficulty of subsequent waste sorting and increases the workload of relevant personnel. Utility Model Content
[0005] The purpose of this invention is to solve the problem of the inability to accurately classify and sort construction waste in the existing technology, and to propose a construction waste pretreatment and leveling device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A construction waste pretreatment and leveling device includes a workbench and a conveyor belt for conveying construction waste. An isolation cover, a first support, and a second support are fixedly installed on the workbench. The isolation cover has a one-way feed port for conveying the construction waste. A base corresponding to the isolation cover is provided on the workbench, and a vibrating plate is positioned above the base. The vibrating plate is integrally connected to a first sieve plate, a second sieve plate, and a collection frame for screening the construction waste. A vibration assembly for driving the vibrating plate to reciprocate is provided on the base. A magnetic separator is fixedly installed on the second support. An adsorption cylinder for adsorbing and collecting plastic is fixedly installed on the second support. A leveling platform for receiving construction waste is provided on the workbench. A leveling plate corresponding to the leveling platform and used for pressing and leveling the construction waste is provided on the workbench via a pressing assembly.
[0007] Preferably, a door is connected to one side of the isolation cover by a pin, and an inclined plate corresponding to the conveyor belt and used for conveying construction waste is fixedly installed on the isolation cover. The inclined plate has a U-shaped structure. A material inlet corresponding to the collection frame is opened on the isolation cover. The base has a U-shaped structure and is horizontally set on the workbench. The first screen plate, the second screen plate, the collection frame and the vibrating plate are arranged horizontally from top to bottom. An electric telescopic rod is fixedly installed on one side of the screen plate, and a push plate for pushing the material residue on the first screen plate is fixedly connected to the output end of the electric telescopic rod.
[0008] Preferably, the vibration assembly includes two fixed cylinders fixedly installed on the base, a limiting block is fixedly installed on the fixed cylinder, and an abutment plate that moves against the vibration plate is slidably sleeved inside the limiting block; The workbench is fixedly equipped with a motor, and the output end of the motor is fixedly connected to a rotating shaft. The rotating shaft is fixedly connected to a traction rod. The traction rod is movably connected to the contact plate bracket, and the two ends of the movable rod are respectively connected to the traction rod and the contact plate pin. The vibrating plate is fixedly mounted with symmetrically arranged fixed rods that extend into the fixed cylinder. A spring is welded between the fixed rod and the base, and the spring is vertically welded to the lower end of the fixed rod extending into the fixed cylinder.
[0009] Preferably, the magnetic separator is horizontally arranged, the adsorption cylinder is vertically arranged, and a fan is fixedly installed on the adsorption cylinder. The adsorption cylinder is a cylindrical structure with an open bottom. The magnetic separator and the adsorption cylinder are arranged above the conveyor belt, and the spreading platform is arranged below the conveyor belt.
[0010] Preferably, the pressing assembly includes an adjustment frame fixedly installed on the workbench, and symmetrically arranged hydraulic cylinders are fixedly installed on the adjustment frame.

[0012] Compared with the prior art, the present invention has the following advantages: 1. In this utility model, the rotating shaft is driven by a motor, and the output end of the motor of the movable rod drives the rotating shaft to start rotating. The rotating shaft drives the traction rod to rotate synchronously. The traction rod pulls the contact plate to move up and down through the movable rod. The contact plate pushes the vibrating plate to move up and down. The construction waste is initially classified by vibration. The magnetic separator above the conveyor belt separates the metal waste, and the adsorption cylinder separates the lightweight plastic bags, making the classification of construction waste more comprehensive and reducing the labor intensity of subsequent workers.
[0013] 2. In this utility model, the output end of the hydraulic cylinder drives the moving block to slide within the adjusting frame.

Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] Reference Figures 1-6 A construction waste pretreatment and leveling device includes a workbench 1 and a conveyor belt 17 for conveying construction waste. Additionally, a controller electrically connected to a motor 42 and a hydraulic cylinder 91 is fixedly installed on the workbench 1.
[0019] Additional information: The guide block and the adjustment frame 95 are integrated, and the electric guide rail and the guide block work together to make the adjustment frame move up and down.
[0020] The conveyor belt 17 is the core of the material conveying system. One end receives the screened waste, and the other end conveys the material to the platform 14. The conveying speed can be adjusted according to the pre-processing volume, and the surface is treated with anti-slip treatment.
[0021] The workbench 1 is fixedly equipped with an isolation cover, a support 1 2, and a support 2 3. The isolation cover is provided with a one-way feed port 15 for conveying construction waste. The one-way feed port 15 is the only feeding channel for construction waste, which not only facilitates the pouring of materials, but also prevents dust from overflowing from the feed port during screening.
[0022] The workbench 1 is provided with a base 41 corresponding to the isolation cover, and a vibrating plate 5 is provided above the base 41. The vibrating plate 5 is integrally connected with a sieve plate 6, a sieve plate 7 for screening construction waste and a collection frame 8. The base 41 is provided with a vibration component 4 for driving the vibrating plate 5 to vibrate back and forth. A magnetic separator 11 is fixedly installed on the support 2. An adsorption cylinder 12 for adsorbing and collecting plastic is fixedly installed on the support 3. The workbench 1 is provided with a spreading platform 14 for receiving construction waste. A spreading plate 94 corresponding to the spreading platform 14 and used to press and flatten the construction waste is provided on the workbench 1 through a pressing component 9.
[0023] A door is connected to one side of the isolation cover by a pin. The door is located on the other side of the isolation cover. It is normally closed to maintain a seal. It can be opened when maintenance is required for screen plate 1 6, screen plate 2 7 and vibration assembly 4. There is enough operating space to facilitate personnel to inspect or clean blocked materials.
[0024] Furthermore, the isolation cover is fixedly installed with an inclined plate corresponding to the conveyor belt 17 for conveying construction waste. The inclined plate has a U-shaped structure. By designing the inclined plate as a U-shaped structure, the baffles on both sides prevent the material from falling off the sides of the inclined plate during the sliding process, ensuring that all the material enters the subsequent screening stage.
[0025] The isolation cover has a material inlet 16 corresponding to the collection frame 8. The material inlet 16 is a rectangular opening and its size matches that of the collection frame 8. It is normally sealed with a cover plate. When the material in the collection frame 8 accumulates to a certain amount, the cover plate can be opened to directly remove the collection frame 8 without disassembling the isolation cover, thus improving the material cleaning efficiency.
[0026] The base 41 has a U-shaped structure and is horizontally set on the workbench 1. The first screen plate 6, the second screen plate 7, the collection frame 8 and the vibrating plate 5 are horizontally set from top to bottom. The first screen plate 6 is located on the top layer and has the largest aperture. It is used to separate "large waste materials" (such as whole bricks, concrete blocks and large pieces of gravel) to prevent large materials from entering the subsequent fine screening process and causing blockage.
[0027] Screen plate 27 is located in the middle layer with medium-sized pores. It is used to separate "medium-sized aggregates" (such as small crushed stones, sand, and broken bricks). These materials can be used directly as raw materials for recycled aggregates.
[0028] The collection box 8 is located at the bottom layer and has no aperture. It is used to collect "fine powder materials" (such as cement dust, soil dust, and fine sand). After collection, it can be used for recycled mortar or landfill cover soil.
[0029] An electric telescopic rod is fixedly installed on the side of the screen plate 6, and a push plate 10 for pushing the material residue on the screen plate 6 is fixedly connected to the output end of the electric telescopic rod. The width of the push plate 10 is the same as that of the screen plate 6. When large pieces of material accumulate to a certain thickness on the screen plate 6, the electric telescopic rod pushes the push plate 10 to move along the surface of the screen plate 6, pushing the large pieces of material to the designated collection area outside the isolation cover to avoid clogging of the screen plate 6.
[0030] The vibration assembly 4 includes two fixed cylinders fixedly installed on the base 41. A limiting block is fixedly installed on the fixed cylinder, and an abutment plate 46 that moves against the vibration plate 5 is slidably sleeved inside the limiting block. The limiting block guides the abutment plate 46, so that the abutment plate 46 moves smoothly up and down.
[0031] A motor 42 is fixedly installed on the workbench 1, and a rotating shaft 43 is fixedly connected to the output end of the motor 42. A traction rod 44 is fixedly connected to the rotating shaft 43. A movable rod 45 is movably connected to the support of the contact plate 46. The two ends of the movable rod 45 are respectively connected to the pin shafts of the traction rod 44 and the contact plate 46. When the contact plate 46 moves up and down, it directly pushes the vibrating plate to provide power for screening.
[0032] A fixed rod 47 is symmetrically arranged and extends into the fixed cylinder on the vibrating plate 5. A spring 48 is welded between the fixed rod 47 and the base 41. The spring 48 is vertically welded to the lower end of the fixed rod 47 extending into the fixed cylinder. The spring 48 buffers the impact force of the vibrating plate 5 and avoids hard contact that could cause wear on the components.
[0033] The magnetic separator 11 is set horizontally to completely cover the width of the conveyor belt 17, ensuring that all materials pass through the magnetic separation area. When the screened material moves with the conveyor belt 17 to below the magnetic separator 11, the magnetic metal in it is attracted by the magnetic separator. When the metal accumulates to a certain amount, the metal is manually peeled off from the surface of the magnetic separator 11 to achieve the separation of aggregate and metal.
[0034] The adsorption cylinder 12 is set vertically, and an exhaust fan 13 is fixedly installed on the adsorption cylinder 12. The adsorption cylinder 12 is a cylindrical structure with an open bottom. When the exhaust fan 13 runs, it creates a negative pressure environment inside the adsorption cylinder 12. When the material conveyed by the conveyor belt 17 passes under the adsorption cylinder 12, the lightweight plastic is sucked into the adsorption cylinder 12 due to its light weight and eventually accumulates inside the adsorption cylinder 12. The collected plastic can be cleaned by periodically opening the valve at the bottom of the cylinder.
[0035] The magnetic separator 11 and the adsorption cylinder 12 are positioned above the conveyor belt 17, and the spreading platform 14 is positioned below the conveyor belt 17.
[0036] The pressing assembly 9 includes an adjustment frame 95 fixedly installed on the worktable 1. The adjustment frame 95 provides mounting support for the hydraulic cylinder 91 and the connecting frame 92, and also restricts the movement direction of the connecting frame 92.
[0037] A symmetrically arranged hydraulic cylinder 91 is fixedly installed on the adjusting frame 95. A symmetrically arranged connecting frame 92 is slidably sleeved on the adjusting frame 95. A flat plate 94 is placed on the connecting frame 92. A moving block 93 is fixedly connected to the output end of the hydraulic cylinder 91. The moving block 93 guides the connecting frame 92 to slide smoothly along the inner wall of the adjusting frame 95 to avoid jamming.
[0038] The adjusting frame 95 has a U-shaped structure and is set vertically. The moving block 93 has a trapezoidal structure. The spreading plate 94 is set horizontally above the spreading platform 14. The length and width of the spreading plate 94 are both greater than the spreading platform to ensure that the material is completely covered. The surface is treated with wear-resistant material to avoid wear caused by long-term pressing. It moves synchronously with the moving block 93 through the connecting frame 92.
[0039] The functional principle of this utility model can be explained through the following operation methods: When using, put the construction waste into the feed inlet 15; Construction waste falls onto screen plate 6 due to gravity. At this time, the controller sends a start signal to motor 42. The output end of motor 42 drives shaft 43 to start rotating. Shaft 43 drives traction rod 44 to rotate synchronously. Traction rod 44 pulls contact plate 46 to move up and down within limit block through movable rod 45. The contact plate 46 pushes the vibrating plate 5 to move up and down, and the spring 48 is subjected to force. Screen plate 6 and screen plate 7 vibrate synchronously with vibrating plate 5 to classify and screen construction waste. Smaller particles fall through sieve plate 6 into sieve plate 7, and after further screening, the fine impurities finally fall into the collection frame 8. When the material in the collection box 8 and the second sieve plate 7 accumulates to a certain level, it is removed through the material outlet 16. Larger material residues remaining on screen plate 6 are activated by the controller, which sends a start signal to the electric telescopic rod. The output end of the electric telescopic rod drives the push plate 10 to the right, pushing the construction waste onto the inclined plate. Construction waste rolled onto conveyor belt 17; When the conveyor belt 17 transports construction waste past the support 2, the magnetic separator 11 generates a magnetic field to adsorb ferromagnetic metals in the construction waste, thereby separating the metals from other materials. The conveyor belt 17 continues to transport materials to the bottom of the support frame 2 3. The adsorption cylinder 12 generates negative pressure through the exhaust fan 13 at the top, which sucks the lightweight plastic fragments in the construction waste into the adsorption cylinder 12 for collection, thus completing the separation of plastic from other materials. Construction waste, after magnetic separation and plastic separation, falls onto the platform 14 via conveyor belt 17; The adjustment frame 95 drives the paving plate 94 to be adjusted above the paving platform 14 via electric guide rails and guide blocks, and is in close contact with the construction waste; The controller sends a start signal to the hydraulic cylinder 91. The output end of the hydraulic cylinder 91 drives the moving block 93 to slide in the adjustment frame 95. When the moving block 93 moves, it drives the connecting frame 92 and the slab 94 to move back and forth. When the slab 94 moves back and forth, it presses and smooths the construction waste on the slab platform 14 to complete the pre-treatment slab leveling operation. Finally, the paving plate 14, the inclined block 92, and the adjustment frame 95 return to their initial positions. The waste on the paving plate 14 is to be discharged later, awaiting the pretreatment of the next batch of construction waste.
[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
