One of the discharge tanks can convey sand into the mixing structure, and the other discharge tank can convey stones into the mixing structure. The material conveying structure can convey cement into the mixing structure. When the sand, stones and cement enter the mixing structure, the mixing structure receives external water and mixes the materials. The mixed concrete materials are discharged into an external receiving structure.
