Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to an indoor concrete mixer. Background Art

[0002] A concrete mixer is a machine that mixes cement, sand and gravel aggregates and water to make a concrete mixture. It is an important equipment for concrete mixing plants and stabilized soil mixing plants. However, when the amount of concrete required is small, such as in interior decoration, the use of large concrete mixers takes up space, wastes resources, and is inconvenient to move. Therefore, an indoor concrete mixer is needed. Existing indoor concrete mixers have certain disadvantages when in use. If the concrete is not cleaned in time after stopping mixing, it is easy to solidify. The mixing barrel is deep, and the concrete adheres to the mixing shaft, which is difficult to clean and maintain. When water and dry materials are mixed, they are easy to clump, thereby prolonging the mixing time. Therefore, we propose an indoor concrete mixer. Utility Model Content
