When the loading of the concrete raw materials is completed, the elasticity of the spring 18 is used to push the cover plate 19 to return to its original position, and the port of the feed hopper 16 is blocked to prevent the dust generated when pouring the concrete raw materials from floating out, thereby ensuring the environment for concrete processing.
