Description

Technical Field

[0001] This utility model relates to the field of construction waste treatment technology, and in particular to an environmentally friendly construction waste recycling device. Background Technology

[0002] With the rapid advancement of urbanization, the construction industry is booming. While large-scale construction activities have brought about a complete transformation of urban landscapes, they have also generated an astonishing amount of construction waste. Construction waste mainly includes a variety of components such as discarded concrete blocks, bricks, mortar, ceramics, glass, metals, wood, and discarded packaging materials. From the perspective of resource sustainability, construction waste contains a large amount of recyclable resources. Among them, waste concrete and bricks, after being crushed and screened, can be used as recycled aggregates to produce recycled concrete, bricks, or other building materials. This can effectively reduce dependence on the mining of natural aggregates and lower energy consumption and carbon emissions in the production process of building materials.

[0003] However, urban construction and renovation projects, such as the demolition of old buildings and the renovation of large infrastructure, generate a large amount of large-volume construction waste, such as abandoned concrete beams and columns, and large brick and stone structures. Most crushers have small feed openings, making it difficult for large pieces of construction waste to enter. They need to be manually crushed or cut beforehand, a process that is extremely labor-intensive and inefficient. Moreover, even if large pieces of construction waste can be fed into the crusher, the design of the crushing chamber and the configuration of the crushing force are not designed for such large and hard materials, often resulting in incomplete crushing, equipment jamming, or even damage.

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing an environmentally friendly construction waste recycling device.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an environmentally friendly construction waste recycling device, comprising a mounting frame, a stepper motor, a belt drive assembly, an inlet, a fixed shell, pins, and a conveyor belt. The conveyor belt is located below the opening of the mounting frame. The belt drive assembly is connected to a central shaft. A cutter holder is fixedly installed in the middle of the outer ring surface of the central shaft. Multiple sets of long cutters are mounted around the outer side of the cutter holder.

They are rotatably connected to the inner wall of the fixed shell through the pins. The third telescopic cutter assembly includes a flipping plate frame, cutter blocks, a first connecting buckle, a sleeve, a first end cap, a spring, a second end cap, and a movable rod.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides an environmentally friendly construction waste recycling device, including a mounting frame 1, a stepper motor 2, a belt drive assembly 3, a feed inlet 4, a fixed shell 5, pins 51, and a conveyor belt 7. The conveyor belt 7 is located below the opening of the mounting frame 1. The belt drive assembly 3 is connected to a central shaft 10. A cutter holder 9 is fixedly installed in the middle of the outer ring surface of the central shaft 10. Multiple sets of long cutters 8 are installed around the outside of the cutter holder 9. A side crushing mechanism 6 is provided on the outside of the long cutters 8. The side crushing mechanism 6 includes a flipping shell 61, a first telescopic cutter assembly 62, a second telescopic cutter assembly 63, and a third telescopic cutter assembly 64. The first telescopic cutter assembly 62, the second telescopic cutter assembly 63, and the third telescopic cutter assembly 64 have the same structure and are distributed in an arc trajectory on the outside of the long cutters 8. They are rotatably connected to the inner wall of the fixed shell 5 by pins 51. The third telescopic cutter assembly 64 includes a flipping plate frame 641 and a cutter block 642. The system comprises a first connecting buckle 643, a sleeve 644, a first end cap 645, a spring 646, a second end cap 647, and a movable rod 648. Multiple sets of tool blocks 642 are fixedly installed on one side of the flip plate frame 641 in an arc-shaped trajectory. The flip plate frame 641 is movably connected to the movable rod 648 via the first connecting buckle 643. The second end cap 647 is threaded onto the outer ring surface of the movable rod 648. The spring 646 is located outside the movable rod 648 and fixedly connected to one side of the second end cap 647. The other end of the spring 646 is fixedly connected to the first end cap 645. The first end cap 645 is movably connected to the movable rod 648 and is threaded onto the outside of the flip shell 61. The sleeve 644 is fixedly connected inside the flip shell 61. The movable rod 648 is slidably connected to the inner wall of the sleeve 644. The first connecting buckle 643 is fixedly connected to the end of the movable rod 648 and is movably connected to the flip plate frame 641.

[0023] The specific setup and function of this embodiment are described below: The first telescopic cutter assembly 62, the second telescopic cutter assembly 63, and the third telescopic cutter assembly 64 are distributed around the long cutter 8 in an arc-shaped trajectory. The three have the same structure. Taking the third telescopic cutter assembly 64 as an example, when the long cutter 8 impacts a larger piece of debris, the debris will hit the cutter block 642 and be further broken. Multiple sets of cutter blocks 642 are also distributed on the flipping plate frame 641 in an arc-shaped trajectory to expand the contact range and deal with larger pieces of construction debris. The impact force of the debris acts on the lower end of the flipping plate frame 641, causing it to move in a fan shape around the pin 51. Under the connection of the first connecting buckle 643, the movable rod 648 is pushed outward. The movable rod 648 moves outward along the sleeve 644 and the first end cap 645. At the same time, the movable rod 648 drives the second End cap 647 pulls spring 646, the other end of which is fixed to first end cap 645, which is threaded onto flip shell 61. Therefore, spring 646 is stretched, generating elastic force. This elastic force reacts on second end cap 647, pulling outwardly moving movable rod 648 inward, thus applying a thrust to the lower end of flip frame 641. Flip frame 641 pushes multiple sets of blade blocks 642 to impact larger pieces of construction waste. This repeated impact of multiple sets of blade blocks 642 on larger pieces of construction waste achieves the function of crushing larger waste. First telescopic blade assembly 62 and second telescopic blade assembly 63 crush in the same way. With the three components working in sequence with rotating long blade 8, larger pieces of construction waste are crushed multiple times, breaking them into smaller pieces for easier subsequent crushing and recycling operations.

[0024] Example 2: Figure 1 - Figure 4 As shown, the first telescopic cutter assembly 62, the second telescopic cutter assembly 63, and the third telescopic cutter assembly 64 are respectively fixedly installed in the middle of the flip shell 61. The lower end of the flip shell 61 is rotatably connected to the lower end of the fixed shell 5. The side crushing mechanism 6 also includes a connecting plate 65, an electric cylinder 66, and a second connecting buckle 67. The flip shell 61 is movably connected to the end of the movable rod of the electric cylinder 66 through the second connecting buckle 67. The electric cylinder 66 is installed on the upper side of the mounting frame 1 through the connecting plate 65. The belt drive assembly 3 is connected to the stepper motor 2. The feed port 4 is fixedly connected to the upper end of the fixed shell 5. The central shaft 10 is rotatably connected to the middle of the fixed shell 5. The fixed shell 5 is fixedly installed above the opening of the mounting frame 1.

[0025] The overall effect of this embodiment is that the fixed shell 5 is designed as an inverted trapezoid, which makes it easier for larger pieces of construction waste to enter the crushing chamber composed of the fixed shell 5 and the flip shell 61. By periodically unscrewing multiple sets of pins 51, the movable rod of the electric cylinder 66 is controlled to retract. Under the connection of the second connecting buckle 67, the flip shell 61 is pulled, causing it to rotate around the connection point with the lower end of the fixed shell 5, thereby separating the flip shell 61 from the fixed shell 5, which is convenient for operators to inspect and replace.

[0026] The device's operation and working principle are as follows: The stepper motor 2 is started, injecting power into the belt drive assembly 3, which in turn drives the central shaft 10 to rotate. This, in turn, drives the cutter holder 9 and its multiple sets of long cutters 8 to rotate clockwise, allowing larger pieces of construction waste to be fed in through the inlet 4. The first telescopic cutter assembly 62, the second telescopic cutter assembly 63, and the third telescopic cutter assembly 64 are distributed in an arc-shaped trajectory around the long cutters 8. All three have the same structure. Taking the third telescopic cutter assembly 64 as an example, when the long cutters 8 impact the larger pieces of waste... The impact of the impactor on the blade block 642 further breaks it apart. Multiple sets of blade blocks 642 are also distributed in an arc-shaped trajectory on the tilting plate frame 641 to expand the contact range and deal with larger pieces of construction waste. The impact force of the waste acts on the lower end of the tilting plate frame 641, causing it to move in a fan shape around the pin 51. Under the connection of the first connecting buckle 643, it pushes the movable rod 648 outward. The movable rod 648 moves outward along the sleeve 644 and the first end cap 645. At the same time, the movable rod 648 drives the second end cap 647 to pull the spring 646. The other end of 6 is fixed to the first end cap 645, which is threaded onto the flipping shell 61. Therefore, the spring 646 is stretched, generating elastic force. This elastic force reacts on the second end cap 647, pulling the outwardly moving movable rod 648 inward, thus applying a thrust to the lower end of the flipping frame 641. The flipping frame 641 pushes multiple sets of blade blocks 642 to impact larger pieces of construction waste. Thus, the multiple sets of blade blocks 642 repeatedly impact larger pieces of construction waste, achieving the function of crushing larger waste. The first telescopic blade assembly 62... The second telescopic cutter assembly 63 crushes in the same way. With the three components working in sequence with the rotating long cutter 8, larger pieces of construction waste are crushed multiple times. The crushed waste falls from the opening of the mounting frame 1 onto the conveyor belt 7 and is transported outward for subsequent operations. Multiple sets of pins 51 are periodically unscrewed, and the movable rod of the electric cylinder 66 is controlled to retract. Under the connection of the second connecting buckle 67, the flip shell 61 is pulled, causing it to rotate around the connection point with the lower end of the fixed shell 5, thereby separating the flip shell 61 from the fixed shell 5, which is convenient for operators to inspect and replace.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
