Description

Technical Field

[0001] The invention relates to the technical field of concrete batching, in particular to a concrete batching machine for concrete production and a batching method thereof. Background Art

[0002] A concrete batching machine is a machine used to store and measure various sand and stone aggregates in concrete or asphalt mixing plants, and transport them to the mixer according to a pre-set formula to mix them with cement, fly ash, mineral powder, additives, water, etc. to form concrete. It is mainly used in the concrete construction industry.

[0003] After searching, a concrete batching device and a batching method disclosed in the invention patent with Chinese patent announcement number "CN118386412A" include a silo, a pressure dividing platform and a material discharge driver. The pressure dividing platform is fixedly arranged inside the silo to separate the chamber into a storage chamber and a material discharge chamber distributed upper and lower, and a material discharge window connecting the storage chamber and the material discharge chamber is provided between the pressure dividing platform and the inner wall of the silo. The material discharge driver can open / close the material discharge window. The pressure dividing platform divides the material in the silo horizontally on the side of the pressure dividing platform, so that the horizontal pressure of the material in the central part of the silo is reduced, thereby reducing the possibility of material agglomeration. When the material discharge plate valve is opened, the material in the material discharge chamber is discharged, while the material in the storage chamber is still in a sealed state and will not contact with the humid air at the discharge port, further reducing the possibility of material agglomeration.

[0004] Although the device can reduce material agglomeration, it lacks a material conveying system. Considering that the material is heavy and the silo is high, the operator needs to convey the material to the silo. For heavy materials and high silos, this undoubtedly increases the labor intensity of the operator, resulting in low production efficiency of the entire concrete production line. Therefore, a concrete batching machine for concrete production and a batching method thereof are proposed to solve the above-mentioned problems. Summary of the invention
