Technical Field

[0001] The utility model belongs to the technical field of aggregate bins, in particular to a concrete batching aggregate bin. Background Art

[0002] Concrete refers to cement as the binder, sand and stone as aggregates; it is mixed with water (which may contain admixtures and additives) in a certain proportion and obtained by mixing. It is also called ordinary concrete. Aggregate silos are usually used in the batching system of concrete mixing plants, mainly to store aggregates such as sand and stone in concrete.

[0003] The current concrete batching aggregate silo usually consists of a bracket and an aggregate silo body fixedly mounted on the bracket, that is, concrete batching is put into the aggregate silo body, and when the concrete batching is needed, the valve of the discharge port on the aggregate silo body is opened to discharge the concrete.

[0004] Since the mixing ratios of aggregates such as gravel, coarse sand and fine sand in concrete are different, the feeding amounts are also different. Once the feeding amount is not adjusted properly, the mixing ratio may be unbalanced, thereby affecting the strength and quality of the concrete. Therefore, a concrete batching aggregate silo is proposed to address the above problems. Utility Model Content
