Description

Technical Field

[0001] The utility model relates to the field of concrete production, and particularly relates to a concrete aggregate conveying structure. Background Technique

[0002] Concrete aggregate refers to granular loose materials that play a role of skeleton or filling in concrete, and is divided into coarse aggregate and fine aggregate. Coarse aggregate generally refers to pebbles, crushed stones, etc., and fine aggregate generally refers to natural sand, artificial sand, etc. When producing concrete, the aggregate, powder and water are mixed, and modified by adding admixtures to prepare concrete products that meet the requirements.

[0003] In the mixing process of concrete materials, the dosage of concrete aggregate is calculated in "cubic meters". However, the existing concrete aggregate is often added to concrete materials through a bucket or a conveyor belt. During the addition of concrete aggregate, it is difficult to calculate the added dosage during the conveying process of concrete aggregate. For this reason, we propose a concrete aggregate conveying structure. Content of the Utility Model
