Description

Technical Field

[0001] The utility model relates to the technical field of concrete mixing stations, in particular to a concrete mixing station with double intermediate warehouses. Background Art

[0002] Concrete mixing station is mainly composed of mixing host, material weighing system, material conveying system, material storage system and control system and other ancillary facilities. The material is weighed by the material weighing system and then output to the material conveying system, and finally enters the mixer. An intermediate warehouse is usually set above the mixer for temporary storage of materials. When the concrete mixing station is in use, the intermediate warehouse mainly adopts a single warehouse structure, which leads to slow feeding and low mixing efficiency.

[0003] In the prior art, a Chinese patent document with publication number CN217476282U is proposed to solve the above technical problems. The technical solution disclosed in the patent document is as follows: a concrete mixing station with double intermediate bins, which includes a support box, a PLC controller is fixedly installed on one side surface of the support box, and two symmetrically arranged intermediate bin bodies are fixedly installed on the top of the support box, and the two intermediate bin bodies are connected to the support box.

[0004] In order to solve the problem of slow feeding and low mixing efficiency due to the single-bin structure of the intermediate bin in the concrete mixing plant, the prior art adopts two sets of intermediate bins for processing. However, when adding concrete raw materials, some dust will float out from the top of the bin or adhere to the inner wall, which will cause dust to float and pollute the environment and waste resources, and the dust will adhere to the inner wall and is difficult to clean.
