Description

Technical Field

[0002] In the process of municipal road construction and maintenance, the paving of asphalt pavement is a crucial process, and its quality is directly related to the service life of the road, driving safety and the overall image of the city. The traditional asphalt paving process usually relies on manual operation and relatively simple mechanical equipment, including multiple independent steps such as on-site mixing, transportation and compaction. However, this traditional construction method has many shortcomings: on the one hand, due to the low efficiency of manual mixing and transportation, the entire construction process takes a long time, and it is easy to cause excessive fatigue of personnel during the peak construction period; on the other hand, the inaccuracy and uncontrollability of manual operation often lead to uneven paving and insufficient compaction, which in turn affects the flatness and structural strength of the road. In addition, the traditional mixing method is difficult to ensure the uniform mixing of materials, especially in cold seasons, when asphalt materials are prone to lose fluidity due to temperature drops, thus affecting the construction quality.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention greatly simplifies the multi-step process in the traditional construction process by integrating the mixing, conveying and compacting functions into one design. Workers can achieve integrated operations from raw material mixing to laying and compacting by only pulling the push rod to move the entire device. This not only reduces the links that require multiple manual interventions in traditional construction methods, but also significantly reduces the physical labor intensity of workers and greatly improves construction efficiency.

[0015] 2. In the present invention, by arranging a heating tank and a heating wire inside the mixing box, continuous heating can be used to maintain the fluidity and construction performance of the asphalt material, effectively preventing the asphalt from hardening and solidifying due to temperature reduction during the mixing and paving process. At the same time, the design of the mixing mechanism adopts a multi-stage transmission and multi-directional mixing method, which improves the mixing efficiency and can ensure that the asphalt material is fully mixed in a shorter time, avoiding local uneven mixing. This not only improves the consistency of the material, but also ensures the quality of the final paving.

[0016] 3. In the present invention, the compaction mechanism drives the turntable to rotate through the No. 3 driving motor, and then drives the compaction plate to do up and down reciprocating motion through the traction rod and the transmission rod. This design makes the compaction action more stable and controllable. The compaction plate can act on the laid asphalt layer with consistent pressure, thereby avoiding the problems of poor road surface flatness and insufficient bearing capacity caused by uneven compaction. Uniform compaction can not only improve the flatness and aesthetics of the road surface, but also enhance the overall strength and durability of the road structure, reduce cracks or potholes that may appear in the future, and extend the service life of the road.

[0017] 4. In the present invention, the coordinated work of the stirring mechanism and the discharging mechanism ensures that the asphalt material can be evenly laid on the ground after being evenly stirred. The design of the main discharge pipe and the branch discharge pipe in the discharging mechanism enables the asphalt material to be evenly dispersed along a predetermined path to form a paving layer with uniform thickness. Combined with the compaction treatment of the tamping mechanism, it can ensure that each asphalt layer laid reaches the expected density and flatness, thereby optimizing the construction quality and improving the safety and comfort of the road.
