Description

Technical Field

[0001] This utility model relates to the field of pavers for road construction, and in particular to a portable mixture processing and separation device. Background Technology

[0002] Segregation, also known as aggregate stratification, refers to the uneven distribution of coarse and fine particles in asphalt mixtures after mixing, during transportation, paving, or compaction. This uneven distribution, caused by a combination of factors, results in localized areas of excessive concentration of aggregates or fine materials. This non-uniform distribution significantly reduces the homogeneity of the mixture, negatively impacting the performance and quality of the final structure.

[0003] During mechanical paving, after the mixture is paved using mechanical equipment, it is often observed that there is a significant excess of aggregate on both sides of the machine, and strips of exposed aggregate appear on the compacted surface. This phenomenon is a typical manifestation of segregation after mechanical paving.

[0004] During manual paving, improper use of paving tools or lack of operational skills may cause coarse and fine aggregates to concentrate in localized areas, resulting in segregation. This segregation caused by human factors can also negatively impact the uniformity of the mixture.

[0005] Segregation of the mixture can have a significant impact on the quality of engineering projects, specifically in the following aspects:

[0006] First, poor surface smoothness. Segregation leads to a decrease in road surface smoothness, thus affecting driving comfort. Uneven road surfaces not only reduce the driving experience but may also increase vehicle wear and tear.

[0007] Secondly, the structural strength is uneven. Segregation results in an uneven internal structure of the mixture, which reduces the overall load-bearing capacity and durability of the structure. Under heavy loads or during long-term use, an uneven structure is more prone to damage and cracking.

[0008] Finally, early pavement damage. In asphalt pavement construction, asphalt mixture segregation is one of the major causes of early damage to asphalt concrete pavements. Segregation leads to problems such as localized loosening and potholes during pavement use, thus shortening the pavement's service life and increasing maintenance costs.

[0009] To avoid the negative impact of mixture segregation, strict control must be exercised over all aspects of the construction process, including mixing, transportation, paving, and compaction, to ensure the uniformity of the mixture and the quality of the final structure. Utility Model Content

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other. Fixing methods not described herein can be any type of fixing, such as threaded fixing, bolt fixing, or adhesive bonding.

[0035] Example 1: Combining Figure 1 and Figure 2 A portable mixture processing and separation device, characterized in that,

[0036] The device includes a housing 1 on which a screen 8 can be detachably mounted;

[0037] The screen mesh 8 is arranged at an angle;

[0038] The housing 1 includes an openable cover 2, on which a handle 3 is arranged;

[0039] The housing 1 is mounted on the fabric feeder 9;

[0040] The discharge port of the material preparation hopper 10 corresponds to the screen 8;

[0041] The inclined screen 8 is positioned below the inlet of the material distributor 9. The substantive technical effects and implementation process of this technical solution, i.e., its basic functions, are as follows:

[0042] During the construction of the base and surface layers, factors related to materials, processes, and the environment can cause localized exposed aggregate and loose aggregate, as well as concentrated coarse aggregate at joints that affects the overall integrity of the pavement – ​​a phenomenon known as aggregate segregation. Segregation leads to problems such as cracks and abnormal porosity, causing severe damage to the pavement within its normal service life and shortening its lifespan.

[0043] The common approach is to manually screen coarse aggregates at joints or segregation areas, spread fine aggregates, and then manually pave and compact the mixture to improve the initial compaction. This method is labor-intensive and slow. To address concrete segregation, a portable treatment device is designed that combines portability, practicality, and high efficiency.

[0044] It mainly addresses the problems of high manpower requirements and slow construction efficiency in the manual treatment of local segregation.

[0045] This device is easy to install and can be mounted on the back of the paver's auger spreader. The screen is modular, allowing for easy replacement with screens of different apertures to accommodate various materials. The screen is positioned at a 145° angle to the storage hopper, and a vibrating motor is installed to improve screening efficiency. Coarse aggregate flows along the screen into the paver's spreader, where it is automatically collected and mixed with the spreader material, avoiding secondary processing.

[0046] The 20L hopper with a detachable screen is directly connected to the distributor. After separation, the fine material can be directly used for local segregation treatment, improving construction efficiency.

[0047] This equipment features modular screening and vibration assistance functions. Its lightweight structure and high degree of automation make it suitable for use by construction site personnel. The amplitude can be adjusted automatically, reducing manual intervention and manpower, and avoiding the risk of mechanical injury caused by personnel repeatedly screening materials and entering the compaction area.

[0048] Example 2: As a further improvement, parallel, or optional independent solution, a vibration motor is mounted on the outside of the housing 1. The substantive technical effect and implementation process of this technical solution, i.e., its basic function, are as follows: the vibration motor can be fixed to the housing with bolts.

[0049] Example 3: As a further improvement, parallel, or optional independent solution, a rubber support structure 6 is arranged inside the housing 1. The top of the rubber support structure 6 presses against the bottom of the screen 8, enabling the screen 8 to vibrate. The substantive technical effect and implementation process of this technical solution, i.e., its basic function, are as follows: Alternatively, this solution can be replaced by an elastic ball. An elastic rubber ball with a diameter of 30mm is installed below the screen, which automatically bounces against the screen surface during vibration to prevent particles from getting stuck.

[0050] Example 4: As a further improvement, parallel solution, or optional independent solution, the edge of the screen 8 is a stepped surface, and the four walls of the shell are also stepped surfaces, thus the screen can be installed on the shell. The substantial technical effect and implementation process of this technical solution, i.e., its basic function, are as follows: This embodiment enables rapid alignment and installation.

[0051] Example 5: As a further improvement, parallel solution, or optional independent solution, it also includes bolts for fixing the screen, the bolts passing through the edge of the housing to fix the screen 8. The substantial technical effect and implementation process of the technical solution here, i.e., its basic function, are as follows: the fixed structure is within the protection scope of this patent.

[0052] Example 6: As a further improvement, parallel solution, or optional independent solution, the screen and the lower horizontal opening of the storage hopper are arranged at 145°. The substantive technical effect and implementation process of the technical solution here, i.e., the basic function, are as follows: similar angles are all within the protection scope of this patent.

[0053] Innovatively, each of the above effects exists independently, yet a single structure can be used to combine the results.

[0054] It should be noted that the multiple modules in this patent are an integration of existing technology modules and do not involve any new modules. Even if some modules use programs, those programs are undoubtedly known programs.

[0055] It should be noted that the multiple solutions provided in this patent include their own basic solutions, which are independent of each other and do not restrict each other. However, they can also be combined with each other without conflict to achieve multiple effects.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
