Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of building material processing equipment, specifically to an integrated device for recycling dual waste resources to enhance water-stabilized aggregates. Background Technology
[0002] In the field of road construction, cement-stabilized aggregates (referred to as water-stabilized aggregates) are widely used as base course materials due to their excellent mechanical properties and stability. Traditional water-stabilized aggregate production mainly relies on raw materials such as natural sand and gravel. However, with the continuous expansion of infrastructure construction, natural aggregate resources are becoming increasingly scarce. Over-exploitation not only leads to ecological damage but also causes a continuous rise in production costs. At the same time, large amounts of solid waste such as industrial waste (such as fly ash and slag) and construction waste accumulate, occupying land resources and causing serious environmental pollution problems.
[0003] In the preparation of water-stabilized aggregates, crushing and screening are crucial steps, as their effectiveness directly impacts the quality and performance of the aggregates. Currently, most existing water-stabilized aggregate crushing and screening devices employ a step-by-step approach: first, the raw materials are crushed using crushing equipment, and then the crushed material is transferred to screening equipment for further screening.
[0004] This step-by-step processing method, because the crushing and screening processes are independent of each other, requires materials to be transferred multiple times between different devices, which not only increases the input of manpower and resources, but also prolongs the entire production cycle, resulting in a significant reduction in production efficiency.
[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0026] 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.
[0027] Please see Figures 1-6This utility model provides a technical solution: an integrated device for recycling dual waste resources to strengthen water-stabilized aggregate, including a support 1. A crushing box 2, a conveying box 3 and a receiving box 4 are installed on the support 1 from top to bottom. A crushing roller 5 is symmetrically rotated inside the crushing box 2. A drive mechanism for driving the crushing roller 5 to rotate is installed on the support 1. A conveying mechanism for conveying materials is provided inside the conveying box 3. A screen plate 10 is slidably inserted inside the crushing box 2. The screen plate 10 is located below the crushing roller 5.
[0028] Specifically, bracket 1 serves as the supporting foundation for the entire device, providing a stable installation structure for crushing box 2, conveying box 3, and receiving box 4. The crushing rollers 5, symmetrically installed inside crushing box 2, rotate relative to each other under the drive mechanism, squeezing and shearing the waste materials entering crushing box 2. The crushed material falls to screen plate 10 by gravity, where it undergoes preliminary screening. Material of the acceptable particle size falls through the screen holes into conveying box 3, while unacceptable material remains on screen plate 10 for further crushing. The conveying mechanism inside conveying box 3 transports the screened material to receiving box 4 for collection. This structural design integrates crushing, screening, and conveying functions, reducing material transfer between different devices compared to traditional multi-step processing devices, shortening the production cycle, and improving production efficiency. Simultaneously, the integrated layout saves equipment floor space and reduces equipment installation and operating costs.
[0029] See Figure 3 The conveyor box 3 has a feed inlet and a discharge outlet. The crushing box 2 has a rectangular frame structure, with its bottom opening facing the feed inlet of the conveyor box 3. The receiving box 4 faces the discharge outlet of the conveyor box 3.
[0030] Specifically, the crushing box 2 has a rectangular frame structure with its bottom opening facing the feed inlet of the conveying box 3, allowing the crushed material to fall directly into the conveying box 3 under gravity without the need for additional conveying equipment. The receiving box 4 faces the discharge outlet of the conveying box 3, ensuring smooth material transport from the conveying box 3 to the receiving box 4, forming a continuous material handling process. This layout further simplifies the material transport path, reduces material loss and energy consumption during the transfer process, improves the continuity and stability of material handling, and also reduces the failure rate during equipment operation.
[0031] See Figure 1 The drive mechanism includes a transmission gear 6 installed at the end of the crushing roller 5, with two transmission gears 6 meshing with each other. A crushing motor 7 is also installed on the bracket 1, and the drive end of the crushing motor 7 is connected to one of the transmission gears 6.
[0032] Specifically, the transmission gear 6 in the drive mechanism is installed at the end of the crushing roller 5. The two transmission gears 6 mesh with each other. When the crushing motor 7 drives one of the transmission gears 6 to rotate, the other crushing roller 5 is driven to rotate in the opposite direction through gear meshing, thereby realizing the relative movement of the two crushing rollers 5 to crush the material. This drive method has a simple structure and stable transmission, which can ensure that the two crushing rollers 5 can carry out crushing work with stable speed and torque, improving crushing efficiency and the consistency of crushing effect. At the same time, the gear transmission has high reliability, low maintenance cost, and extends the service life of the equipment.
[0033] See Figure 3 The conveying mechanism includes a conveying motor 8 installed on the side wall of the conveying box 3, and a conveying auger 9 is rotatably installed inside the conveying box 3. The drive end of the conveying motor 8 is connected to one end of the conveying auger 9.
[0034] Specifically, the conveyor motor 8 is installed on the side wall of the conveyor box 3. After starting, it drives the conveyor auger 9 to rotate. The spiral blades of the conveyor auger 9 push the material falling into the conveyor box 3 along the axial direction of the conveyor box 3, so that the material is transported from the feed port of the conveyor box 3 to the discharge port, and finally falls into the receiving box 4. The material conveying by the conveyor auger 9 can adapt to materials of different properties and particle sizes. The conveying process is stable and material blockage is not easy to occur. At the same time, the conveyor motor 8 can adjust the speed according to production needs, flexibly control the material conveying speed, and meet the requirements of different production rhythms.
[0035] See Figure 2 An insertion port is provided on the side wall of the crushing box 2, and the screen plate 10 is inserted into the interior of the crushing box 2 through the insertion port.
[0036] Specifically, this design facilitates the installation, disassembly, and maintenance of the screen plate 10. When the screen plate 10 is worn or clogged, it can be quickly replaced and cleaned, reducing equipment downtime and improving equipment maintainability and production efficiency.
[0037] See Figures 3-6 The sieve plate 10 includes a mounting plate 103 for blocking the insertion port. A mesh plate 101 is sequentially mounted on the mounting plate 103. A lower mesh plate 102 is slidably mounted on the bottom surface of the mesh plate 101. A frame 105 is provided on the top surface of the mesh plate 101. Mesh holes are provided on both the mesh plate 101 and the lower mesh plate 102. The mesh holes of the mesh plate 101 and the mesh holes of the lower mesh plate 102 are connected to form sieve holes for screening materials. An adjustment mechanism is also provided on the mounting plate 103 for driving the lower mesh plate 102 to slide along the length direction of the mesh plate 101 to adjust the size of the sieve holes.
[0038] Specifically, the adjustable screen size design allows the device to adapt to the production needs of various specifications of water-stabilized aggregates, improving the equipment's versatility and flexibility. Users can adjust the screen size in real time according to the actual project's requirements for aggregate particle size, ensuring the stability and diversity of product quality.
[0039] See Figure 4 The shape and size of the mounting plate 103 are adapted to the shape and size of the insertion port, and a pull handle 104 is installed on the side wall of the mounting plate 103 away from the mesh hole plate 101.
[0040] Specifically, the pull handle 104 makes the installation and disassembly of the screen plate 10 more convenient and labor-saving, improving the efficiency of maintenance work; at the same time, the tight fit between the mounting plate 103 and the insertion port ensures the sealing of the screening process, avoids material leakage, reduces dust pollution, and improves the working environment.
[0041] See Figure 1 The adjustment mechanism includes a support plate 108 mounted on the side wall of the mounting plate 103. A servo motor 109 is fixedly mounted on the support plate 108. A flywheel 110 is connected to the drive end of the servo motor 109. A connecting rod 111 is eccentrically hinged to the top surface of the flywheel 110. The end of the connecting rod 111 away from the flywheel 110 is hinged to the bottom surface of the lower perforated plate 102.
[0042] Specifically, the structure is simple and the transmission is precise, enabling smooth and continuous adjustment of the lower mesh plate 102; the setting of the guide plate 106 and the guide rod 107 improves the stability and reliability of the movement of the lower mesh plate 102, ensures the accuracy of the screen hole adjustment, and thus ensures the stability and consistency of the screening effect.
[0043] See Figure 5 A guide plate 106 is installed on the bottom surface of the mesh plate 101, and a guide rod 107 is slidably installed on the guide plate 106. The guide rod 107 is connected to the bottom surface of the lower mesh plate 102.
[0044] Specifically, the combined use of guide plate 106 and guide rod 107 effectively improves the stability and accuracy of the movement of lower mesh plate 102, avoids the lower mesh plate 102 from shifting or shaking during adjustment, ensures the reliability of screen hole adjustment, and thus improves the working performance and screening efficiency of the entire screening system.
[0045] Working principle:
[0046] Crushing stage: The two waste materials enter the crushing box 2 installed on the upper part of the support 1. The crushing motor 7 in the drive mechanism drives the transmission gear 6 to rotate. Since the two transmission gears 6 mesh with each other, the two crushing rollers 5 installed at their ends rotate relative to each other, performing crushing operations such as squeezing and shearing on the raw materials.
[0047] Screening stage: The crushed material falls onto the screen plate 10 located below the crushing roller 5 under gravity. The screen plate 10 consists of an upper perforated plate 101 and a lower perforated plate 102, with their mesh openings forming screen holes. The servo motor 109 in the adjustment mechanism drives the flywheel 110 to rotate, which in turn drives the lower perforated plate 102 to slide along the length of the upper perforated plate 101 via the eccentrically hinged connecting rod 111, thereby adjusting the size of the screen holes and achieving screening of materials of different particle sizes. Materials of qualified particle size fall into the conveyor box 3 below through the screen holes, while unqualified materials remain on the screen plate 10. By removing the screen plate 10, the unqualified materials can be re-crushed.
[0048] Conveying stage: The conveying motor 8 inside the conveying box 3 drives the conveying auger 9 to rotate, conveying the material falling into the conveying box 3 from the inlet to the outlet, and finally falling into the receiving box 4 opposite the outlet for collection.
[0049] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
