Background

Cement concrete is a composite material formed by bonding fine and coarse aggregates with cement (cement paste) and hardening them over a period of time, most commonly in the past with lime-based cements, such as lime paste, however, hydraulic cements such as calcium aluminate cement or portland cement are sometimes used, and non-cement-based concretes, which bind various aggregates directly, include asphalt concretes bound with asphalt and polymer concretes with polymer as a binding material, in which asphalt concrete is often used for road surfaces, when aggregate is mixed with dry portland cement and water, the mixture forms a slurry which is easily poured and formed, the cement reacts with water and other ingredients to form a hard matrix, and the materials are combined to form a durable rock-like material which has many uses. At present, except for a large-scale concrete mixing plant, the other concrete mixing plants mainly adopt a manual operation mode to weigh and convey coarse aggregate, cement, fine aggregate and clear water, even the materials are not strictly controlled, and in addition, the limitation of the existing mixing tanks or manual mixing causes the uneven mixing of the concrete and the poor performance.

For example, the conventional coarse aggregate is mainly conveyed by simple conveyor belts, even manually pushed by a trolley, the conventional coarse aggregate conveying device does not have related weighing parts and cannot weigh the materials in real time, and the conventional conveying device with a part capable of weighing, such as equipment for a mixing plant, is complicated in structure, needs to be matched with various equipment during actual operation, is inconvenient to use and cannot be popularized and used in general occasions.
