Abstract

The invention relates to a cement shell breaking device and a concrete production system, and belongs to the technical field of construction engineering machinery. The cement shell breaking device andthe concrete production system solve the problem of low cement utilization rate in the existing concrete production process. The cement shell breaking device comprises a bucket body, wherein a rotating shaft is arranged inside the bucket body, and a motor is connected to one end of the rotating shaft; at least one group of cutting and grinding cutter assemblies are arranged in the bucket body, the cutting and grinding cutter assemblies comprise fixed blades and rotating blades, one ends of the fixed blades are fixedly connected to the inner wall of the bucket body, and one ends of the rotating blades are fixedly connected to the outer peripheral surface of the rotating shaft; and the front projection of the fixed blades and the rotating blades in the axial direction of the bucket body isprovided with a coincident portion. The concrete production system comprises the cement shell breaking device. The cement shell breaking device and the concrete production system can be used for cement shell breaking and concrete production in the construction process.

Description

Technical field [0001] The invention relates to the technical field of construction engineering machinery, in particular to a cement shell breaking device and a concrete production system. Background technique [0002] Cement inevitably comes into contact with the outside atmosphere in the process of production, transportation and application, and some cement particles harden. These hardened cement particles have a layer of "hard shell" on the surface, and hydration reaction is not easy to occur during application, and even no hydration reaction occurs, especially the cement inside the hard shell. The activity is not activated, and the utilization efficiency of cement is reduced. [0003] At present, the commonly used concrete mixing device in the process of building construction is to directly mix cement, sand and water, and traditional concrete mixing equipment for building construction is mostly not equipped with a cement "hard shell" crushing device, or the cement is manually ...
