Description

Technical Field

[0001] The utility model belongs to the technical field of asphalt pavement paving, and in particular relates to cold-mix cold-paving layer paving equipment. Background Art

[0002] Asphalt pavement has the advantages of good road performance, fast construction speed and easy maintenance, and has become the main paving form for highways and urban roads.

[0003] Cold mix and cold laying asphalt pavement is a simple and efficient roadbed construction process. Its basic construction process is: material preparation, mixture preparation, road surface treatment, laying of cold mix, rolling and leveling, and surface construction. The work process is described as: after the cold mix and cold laying materials are ready, they are mixed to obtain materials suitable for construction, and then the materials are laid on the treated road surface. After the materials are laid, they are rolled and leveled to ensure the flatness of the road surface. Finally, the corresponding road surface construction work is carried out on the completed road surface. At this point, the asphalt pavement has been successfully prepared and has good performance.

[0004] At present, in the construction process of asphalt pavement, material mixers, bulldozers, excavators, rollers and other equipment are used, which play different roles in different construction processes. For example, the material mixer is mainly used to fully mix the asphalt pavement paving materials, and then export them on the road surface to be constructed. The exported materials need to be manually leveled and spread in advance to make them evenly separated, and then they are rolled and leveled by rollers. There are certain disadvantages in this processing process: on the one hand, manual material spreading will consume a lot of manpower costs, and there is a certain time interval between the export and equalization of materials, which affects the processing progress to a certain extent. On the other hand, for roads with larger spans, manual paving obviously cannot meet the work progress. The conventional measure is to control the output and lay the materials step by step, which will undoubtedly affect the work progress and cannot effectively guarantee the use needs of production and processing.

The specific installation and use of the equipment can be effectively known to the technicians in the relevant technical field, and the details will not be repeated here. This embodiment aims to solve the problem of asphalt material export. The real-time paving problem after the material is discharged is further explained as follows: a paving mechanism for paving the discharged material is arranged on one side of the stirring mechanism 1, and the paving mechanism comprises a support frame 2, a cover body 21 is arranged on the support frame 2, a lifting drive cylinder 22 is arranged in the cover body 21, a cross frame 3 is arranged at the lower end of the lifting drive cylinder 22, a shell 4 with a hollow conical table design is arranged at the lower end of the cross frame 3, a lifting and lowering adjustable leveling roller 5 is arranged in the shell 4, and telescopic shells 6 are arranged on both sides of the shell 4, wherein a slide bar assembly is arranged at the inner corner of the telescopic shell 6 and is connected with the shell 4 is connected to the outer corner of the telescopic shell 6, which can not only ensure the stability of the telescopic shell 6 during movement and adjustment, but also improve its smoothness during movement, and has strong functionality. The telescopic shell 6 is provided with extension rollers 7 that are staggered with the leveling rollers 5 and can be raised and lowered. The specific description is: the number of lifting drive cylinders 22 can be freely increased according to the setting specifications of the shell 4 and the telescopic shell 6, and can be selectively set up inside or outside the cover body 21, and the output end of the lifting drive cylinder 22 is hinged with the cross frame 3, of course, its installation end is also the same, the shell 4 is hinged with the cross frame 3, and the shell 4 is hinged with the cross frame 3. The connecting components of the auxiliary peripherals are connected to the cross frame 3 to ensure the stability of the workpiece. The setting specifications of the leveling roller 5 can meet the requirements of a certain span for the flattening of materials. At this time, the extension roller 7 is located at the rear side of the leveling roller 5, especially for further strengthening the leveling of the corners of the asphalt pavement to ensure the pavement forming effect. When paving a large span of pavement, the telescopic adjustment mechanism 8 is used to drive the telescopic shell 6 to move relative to the shell 4, and drive the extension roller 7 to extend one end distance outward to meet different usage requirements and improve the work process.A telescopic adjustment mechanism 8 is arranged above the cross frame 3 to facilitate driving the telescopic shell 6 to telescope and adjust relative to the shell body 4.
