Description

Technical Field

[0001] The utility model relates to the technical field of concrete mixing, in particular to a mixer used in a concrete mixing station. Background Art

[0002] Concrete mixing is an operation method of mixing cement, lime, water and other materials and stirring them evenly. There are two types of concrete mixing: manual mixing and mechanical mixing. Concrete mixing stations are widely used in my country's industrial, agricultural, transportation, national defense, water conservancy, municipal and other construction projects, and the demand is increasing. The mixing method of existing mixers makes the concrete mainly produce one-way flow under the stirring action of the mixing blades, so that the concrete in the mixer cannot be fully mixed, easy to stratify, and poor uniformity. In addition, during the mixing process, part of the concrete will be adsorbed on the inner wall of the mixing chamber under the action of centrifugal force, making it impossible to mix that part of the concrete. After the work is finished, the workers use scrapers to clean and remove it. It is difficult to remove after drying, the labor intensity is high, and the scraper is easy to damage the inner wall of the mixer, affecting the service life. Utility Model Content
