However, in practical applications, the design and operation of the spreader often face some technical challenges, especially those related to the uniformity of concrete distribution.

[0003] The flat outlet is usually designed to achieve uniform distribution in the lateral direction of the distributor, but the shape and size of the outlet have a direct impact on the flow rate and distribution uniformity of the concrete.

[0023] like Figure 1 As shown,

[0024] An asphalt concrete paving device comprises a moving platform 1, a storage box 2 and a concrete paving mechanism 3.

[0025] In this embodiment: Under normal circumstances, the design of the flat outlet is usually to achieve uniform distribution in the horizontal direction of the distributor, but the shape and size of the outlet have a direct impact on the flow rate and distribution uniformity of the concrete. In many cases, due to the wide opening of the flat outlet, the distributor is prone to excessive concrete accumulation in the middle of the road surface when distributing concrete, especially when the hopper is located above the middle of the flat outlet of the distributor. This problem is particularly obvious. This design causes the concrete discharge speed in the middle to be too fast, while the speed on both sides is relatively slow, resulting in the accumulation of the spread concrete in the middle of the road surface, thereby affecting the paving quality. By adding the concrete paving mechanism 3, the concrete discharge process can be made more convenient, and the concrete can be evenly spread on the ground and scraped, thereby reducing the quality problems caused by uneven distribution.

[0026] like Figure 1 - Figure 4 As shown,

[0027] Based on the existing asphalt concrete paving equipment, the concrete can be discharged evenly, thereby improving the uniformity of the distribution of concrete on the road surface, ensuring that the concrete can be more evenly distributed over the entire road width, and reducing quality problems caused by uneven distribution.
