Description

Technical Field

[0002] The grouting machine for ancient building repair is a special equipment for repairing ancient buildings. Grouting refers to the method of repairing the structure of ancient buildings by injecting special materials. This grouting machine usually consists of a grouting pump and a corresponding pipeline system, which is used to transport the grouting material to the part that needs to be repaired. The traditional grouting machine for ancient building repair is equipped with a manual stirring device. The operator manually rotates or moves the stirring device up and down to achieve the stirring of the repair material. At the same time, some grouting machines are equipped with a screw conveyor, which pushes the repair material by rotating a single screw blade to transport the repair material from the storage bin of the grouting machine to the part that needs to be repaired. There are some problems. The traditional grouting machine for ancient building repair is unstable in manual operation and difficult to maintain consistent strength and speed. Manual stirring easily causes uneven stirring of the repair material. At the same time, the conveying area of ​​the single screw conveyor may limit its conveying capacity, and it is easy to cause the risk of blockage when the repair material particles are large or the viscosity is high. For this reason, we propose a grouting machine for ancient building repair. Utility Model Content
