Abstract
Description
Technical Field
[0001] The present application relates to the field of concrete technology, and in particular to an intermittent concrete mixing station. Background Art
[0002] Concrete is a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. The term concrete usually refers to cement as the cementitious material, sand and stone as aggregates; and water (which may contain admixtures and additives) mixed in a certain proportion and obtained by mixing. It is also called ordinary concrete and is widely used in civil engineering.
[0003] However, in existing concrete mixing plants, aggregates and fine materials are first added to the mixing main unit, and then water (additives) are added for mixing. Since the particle diameter of fine materials is smaller than that of aggregates, the fine materials will pass through the gaps between the aggregates and settle downward during the mixing process. Therefore, this mixing method has the problems of long mixing time, insufficient mixing uniformity, and unstable concrete quality. Utility Model Content

A motor is installed on the front sides of the support members, and the output end of the motor is fixedly connected to the front end of the rotating column.
[0012] Through the above solution, the motor can drive the rotating column to rotate, so that the multiple baffles can push the mixed material in the mixing barrel to roll, and cooperate with the stirring rod to stir it evenly.
[0013] Furthermore, a discharge pipe is fixedly connected to the back of the mixing barrel, a discharge valve is installed on the outer surface of the discharge pipe, and a sealing cover is hinged on the outer surface of the mixing barrel.

[0017] Furthermore, a fixing frame is fixedly connected to the upper surface of the base, and two mixing barrels are installed on the upper surface of the fixing frame. The bottom ends of the two mixing barrels are fixedly connected to feeding pipes, and the outer surfaces of the two feeding pipes are installed with feeding valves.
