Description

Technical Field

[0001] This utility model relates to the field of construction waste sorting technology, specifically a construction waste sorting device. Background Technology

[0002] In daily life, with the emergence of waste sorting and treatment devices and the appearance of construction waste, many problems have arisen in terms of sorting and treatment. With the development of technology, people are often dissatisfied with the configuration of existing construction waste sorting devices. Due to the variety of types, the existing construction waste sorting devices are difficult to sort, resulting in low efficiency and no collection of sorted fine sand, which can be reused.

[0003] According to the authorized patent "CN214918052U", a construction waste sorting device includes a sorting box. A motor is located on the left side of the sorting box. A rotating shaft is fixedly connected to the output end of the motor shaft of the motor. A connecting rod is fixedly connected to the top of the rotating shaft. An electric push rod is fixedly connected to the lower right end of the connecting rod. A disc is fixedly connected to the bottom end of the electric push rod. An arched screening plate is located below the disc. A circular screening plate is fixedly connected to the periphery of the arched screening plate. The circular screening plate is cylindrical. The central rotating shaft of the circular screening plate and the central rotating shaft of the electric push rod are on the same straight line. Holes are opened on both the arched screening plate and the circular screening plate. A connecting column is fixedly connected to the top center of the arched screening plate. This device has a simple structure, is convenient and practical, and facilitates the separation of sand from construction waste.

[0004] In the early stages of using the aforementioned technical solutions, sorting methods relied heavily on manual screening. This method was inefficient, labor-intensive, and its sorting accuracy was greatly affected by human factors, making it difficult to meet the needs of large-scale construction waste treatment. Subsequently, some mechanical sorting equipment, such as fixed screen sorters, improved efficiency to some extent. However, because the screen was fixed, it could not be flexibly adjusted according to the diversity of construction waste particle sizes, which easily caused screen blockage, resulting in a significant decrease in sorting efficiency and frequent equipment maintenance. In the packaging stage, the traditional process was even more problematic. In the past, manual packaging was usually used, which not only consumed a lot of manpower but also had low packaging efficiency and high labor costs.

[0005] Therefore, this utility model provides a construction waste sorting device. Utility Model Content

[0024] 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.

[0025] Please see Figure 1-4 A construction waste sorting device includes a separation box 1 and a collection box 2. The collection box 2 is fixedly connected to the outside of the separation box 1. A controller 3 is fixedly connected to the outside of the separation box 1. A sorting mechanism 4 is provided on the top of the separation box 1.

[0026] The sorting mechanism 4 includes a lifting groove 41, a slider 42 is slidably engaged inside the lifting groove 41, a connecting plate 43 is fixedly connected to the outside of the slider 42, a return spring 44 is fixedly connected to the bottom of the slider 42, a placement plate 45 is fixedly connected to the top of the connecting plate 43, a leakage hole 46 is opened in the inner bottom wall of the placement plate 45, a motor 47 is fixedly connected to the outside of the separation box 1, a rotating shaft 48 is fixedly connected to the output end of the motor 47, and a pressing rod 49 is fixedly connected to the outside of the rotating shaft 48.

[0027] Furthermore: the lifting grooves 41 are symmetrically distributed in the outer wall of the separation box 1, the bottom of the return spring 44 is fixedly connected to the inner bottom wall of the lifting grooves 41, the connecting plate 43 is symmetrically and slidably connected to the outside of the separation box 1, the placement plate 45 is located at the top of the separation box 1, the drain holes 46 are evenly distributed in the inner bottom wall of the placement plate 45, the motor 47 is fixedly connected to the outside of the separation box 1, the rotating shaft 48 is rotatably connected to the inside of the separation box 1, and the pressing rods 49 are symmetrically distributed on the outside of the rotating shaft 48, and the pressing rods 49 are located below the placement plate 45.

[0028] It should be noted that the end of the extrusion rod 49 adopts a special arc design, which allows for maximum contact with the bottom surface of the placement plate 45. This ensures that the extrusion pressure on the placement plate 45 is more uniform during the extrusion process, avoiding deformation or damage caused by excessive local stress. At the same time, it ensures that the placement plate 45 can vibrate smoothly up and down, improving the stability and continuity of vibration, thereby improving the sorting efficiency and accuracy of construction waste. In addition, the contact area between the extrusion rod 49 and the placement plate 45 is treated with wear-resistant material, effectively extending the service life of the components and reducing equipment maintenance costs.

[0029] Specifically, the shape of the perforation 46 on the inner bottom wall of the placement plate 45 is not a simple circle, but a polygon optimized by fluid dynamics and particle screening theory. This shape design can effectively reduce the probability of blockage when construction waste particles pass through the perforation 46, and improve screening efficiency. At the same time, the size of the perforation 46 can be modularly designed according to the particle distribution of common construction waste. By replacing the placement plate 45 modules with different specifications of perforation 46, it can quickly adapt to the sorting needs of construction waste in different projects, greatly enhancing the versatility and flexibility of the equipment.

[0030] As a further improvement of this utility model, a packing mechanism 5 is provided on the top of the collection box 2. The packing mechanism 5 includes an electric telescopic rod 51. A push plate 52 is fixedly connected to the output end of the electric telescopic rod 51. A rotating frame 53 is fixedly connected to the top of the collection box 2. A hydraulic cylinder 54 is fixedly connected to the top of the rotating frame 53. A piston rod 55 is fixedly connected to the bottom of the hydraulic cylinder 54. A shaping plate 56 is fixedly connected to the bottom of the piston rod 55. A discharge plate 57 is installed in the outer wall of the collection box 2.

[0031] It should be noted that: the electric telescopic rod 51 is fixedly connected to the outside of the placement plate 45, the push plate 52 is slidably connected to the inside of the placement plate 45, the discharge end of the placement plate 45 is located above the collection box 2, and the shaping plate 56 is movably connected to the inside of the collection box 2 through the hydraulic cylinder 54, and the initial position of the shaping plate 56 is located above the collection box 2.

[0032] Furthermore, traditional equipment often focuses only on the sorting stage, and the subsequent material packaging requires manual labor or additional packaging equipment. This device integrates sorting and packaging functions, realizing integrated operation from the sorting of construction waste to the completion of packaging. This not only reduces labor costs and material losses during transportation, but also improves the continuity and automation of the entire processing flow, reduces the equipment footprint, and increases production efficiency.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] Working principle: First, the motor 47 installed on the outside of the separation box 1 is started. The output end of the motor 47 drives the rotating shaft 48 fixedly connected to it to rotate inside the separation box 1. The pressing rods 49 symmetrically distributed on the outside of the rotating shaft 48 rotate synchronously with the rotating shaft 48. Since the pressing rods 49 are located below the placement plate 45, when the pressing rods 49 rotate to contact the placement plate 45, they will press the placement plate 45 upward. The placement plate 45 is connected to the slider 42 through the connecting plate 43. The slider 42 is slidably engaged in the lifting groove 41. The lifting groove 41 is symmetrically distributed on the outer wall of the separation box 1. The bottom of the slider 42 is also connected to the return spring 44. The other end of the return spring 44 is fixed to the bottom wall of the lifting groove 41. Therefore, when the pressing rods 49 press the placement plate 45, the placement plate 45 moves upward against the elastic force of the return spring 44; when the pressing rods 49 press the placement plate 45, the placement plate 45 moves upward against the elastic force of the return spring 44. After leaving the placement plate 45, the return spring 44 contracts, causing the placement plate 45 to return to its original position. This process is repeated to achieve up-and-down vibration of the placement plate 45, placing the construction waste on the placement plate 45 located at the top of the separation box 1. The bottom wall of the placement plate 45 has evenly distributed perforations 46. During the up-and-down vibration of the placement plate 45, smaller construction waste particles fall into the separation box 1 through the perforations 46 under the action of vibration, while larger construction waste particles remain on the placement plate 45 because they cannot pass through the perforations 46. This achieves the initial sorting of construction waste according to particle size. The operator can flexibly adjust the speed of the motor 47 through the controller 3, thereby adjusting the frequency of the squeezing rod 49 squeezing the placement plate 45 and changing the vibration intensity of the placement plate 45 to meet the sorting requirements of different types of construction waste.

[0035] When the sorted material on the placement plate 45 reaches a certain quantity, the electric telescopic rod 51 fixed to the outside of the placement plate 45 is activated. The output end of the electric telescopic rod 51 pushes the push plate 52 connected to it. The push plate 52 slides inside the placement plate 45, pushing the material on the placement plate 45 towards the discharge end. Since the discharge end of the placement plate 45 is located above the collection box 2, the material is sent into the collection box 2 under the action of the push plate 52. After the material enters the collection box 2, the hydraulic cylinder 54 located on the rotating frame 53 at the top of the collection box 2 starts to work. A piston rod 55 is connected to the collection box 2, and a shaping plate 56 is fixed below the piston rod 55. The hydraulic cylinder 54 drives the piston rod 55 to move the shaping plate 56 downward, compacting the material in the collection box 2. With the strong pressure provided by the hydraulic cylinder 54, the material is compressed into a relatively compact shape, which is convenient for subsequent packaging and transportation. After compaction, the shaping plate 56 is raised back to the initial position by controlling the hydraulic cylinder 54. After packaging, the discharge plate 57 installed on the outer wall of the collection box 2 is opened, and the packaged material can be discharged from the discharge plate 57, completing the entire packaging process.
