[0002] Asphalt pavement is widely used in the construction of medium and high-grade highways in my country due to its good driving comfort and excellent performance. The raw material for asphalt pavement is asphalt mixture, which is a composite material produced by putting various specifications of aggregates into the asphalt mixing plant according to a certain ratio and evenly mixing with asphalt through a series of processing procedures. In the process of continuous production of the asphalt mixing plant, the hot material bin often overflows due to unstable aggregate quality, unreasonable hot material sieve size, and mismatch between the target and production mix ratio. In order to facilitate the recovery of overflow, an overflow bin is usually placed at the overflow port of the asphalt mixing plant to receive it.

[0003] For example, an asphalt mixing plant overflow bin with publication number CN218508168U, the asphalt mixing plant overflow bin provided by the utility model includes a base, an annular wall, an atomizing dust suppression component and a discharge baffle, the annular wall is arranged on the base, the upper end of the annular wall is an open structure, and corresponds to the position of the discharge port of the asphalt mixing plant, so that the aggregate overflowing from the hot material bin is discharged from the discharge port to the asphalt mixing plant overflow bin of the utility model, the atomizing dust suppression component is arranged on the top of the annular wall, and the atomizing dust suppression component continuously sprays water mist during the operation of the asphalt mixing plant to suppress the dust raised by the falling of the overflowing aggregate. Although the purpose of dust suppression can be achieved by spraying water mist, it will also cause more water to be mixed in the overflow. The water will not only increase the weight of the overflow and increase the transportation cost, but also the overflow needs to be dried when it is recovered, which will increase the difficulty of recovery. Therefore, an asphalt mixing plant overflow bin is needed to solve the above problems. Utility Model Content
