Description
Technical Field

[0002] Gravity distribution is a common method of concrete distribution, which is particularly suitable for the production process of precast concrete panels. In this distribution method, the concrete mixture falls freely from the mixer or mixer truck into the precast mold, and gravity is mainly used to achieve the distribution and filling of the concrete. After the distribution, vibration treatment is performed to improve the density and uniformity of the concrete. This distribution method is simple and low in cost, but due to the fluidity of concrete, different components in the mixture (such as sand, gravel and cement slurry) may separate during the vibration process, which is the so-called segregation phenomenon. In addition, the optimization of the quality of concrete through vibration technology increases the distribution cost and consumes more energy. In order to solve the above problems, those skilled in the art are in urgent need of developing a device that can achieve uniform distribution of the mixture at low cost. Utility Model Content
