Technical Field

[0001] The utility model relates to the technical field of asphalt and hot aggregate processing equipment, in particular to an asphalt and hot aggregate pre-mixing storage bin. Background Art

[0002] Asphalt and hot aggregate pre-mixing storage silos refer to equipment used to mix and store asphalt and hot aggregate, and are usually used in asphalt concrete mixing plants in road construction. In this type of equipment, asphalt and hot aggregate are stored separately in storage silos in advance, and after mixing in the mixing plant, they are ready for subsequent road paving work.

[0003] The asphalt and hot aggregate pre-mixing storage silos in the prior art have the following disadvantages during use:

[0004] On the one hand, the two storage bins are fixedly arranged at the top discharge port of the mixing device, so that the asphalt and hot aggregate stored in the two storage bins 51 can only be discharged to fixed positions in the mixing device, thereby reducing the subsequent mixing efficiency;

[0005] Secondly, when the two storage bins are discharging materials into the mixing equipment, they are generally fed continuously and cannot be switched in turn, resulting in poor subsequent mixing effect. For this reason, we have designed an asphalt and hot aggregate pre-mixing storage bin to solve the above problems. Utility Model Content

The alternating reciprocating switching structure can, under the linkage action of the above-mentioned rotating structure, enable the asphalt and hot aggregate loaded in the two storage bins to be discharged into the external mixing equipment in turn.
