Description

Technical Field

[0002] Concrete, also known as "concrete", is a general term for engineering composite materials that are cemented into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion, and the cement concrete obtained by mixing is also called ordinary concrete. It is widely used in civil engineering, and a mixing device is needed to improve the mixing efficiency when mixing concrete with other materials.

[0003] For example, the patent document with application number CN202223024708.X discloses a concrete mixing device. In this utility model concrete mixing device, the conveying wheel inside the feed barrel can allow the material to fall slowly, preventing the material from falling directly into the shell, and the setting of the diverter plate can also divert the material, further preventing the material from falling directly onto the rotating roller and the stirring blades, thereby protecting the rotating roller and the stirring blades, so that the rotating roller and the stirring blades can be used for a longer time. However, the concrete mixing device cannot clean the cement material stuck on its inner wall when in use, which results in the cement solidifying if the sticking time is too long, increasing the later cleaning cost.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an automatic cleaning concrete mixing device is proposed. Utility Model Content
