Technical Field

[0001] The utility model relates to the technical field of concrete preparation, in particular to a concrete preparation device. Background Art

[0002] A concrete preparation device is a device for making concrete. The concrete preparation device can mix cement, aggregate, water and admixtures into concrete in a certain proportion. With the continuous development of the construction industry, the demand for concrete has increased, and the concrete preparation device has been further developed.

[0003] After traditional concrete preparation devices evenly mix the raw materials into concrete, the concrete needs to be poured out for use. Since concrete has a certain viscosity, a portion of the concrete in the preparation device will remain in the preparation device. If the preparation device is not cleaned in time after pouring out the concrete, the concrete will dry on the inner wall of the preparation device, which will affect the life of the concrete preparation device over time and also cause the problem of uneven mixing of the concrete.
