The automation and precision of its mixing and supply are directly related to construction efficiency, project quality and cost control. Traditional concrete mixing and feeding methods mostly use manual operations, which are not only inefficient, but also difficult to ensure the accuracy and uniformity of concrete proportions, which brings hidden dangers to project quality and construction safety. Therefore, the development of a concrete device that can automatically mix and feed has become an urgent need for the development of the industry.
