Mortar scraping device

The invention provides a mortar scraping device. The mortar scraping device comprises a main body, and a mortar scraping surface is arranged at the bottom of the main body; the mortar scraping surface is gradually sunken from the two ends, perpendicular to the advancing direction, of the main body to the middle of the main body so that a mortar scraping area can be formed at the bottom of the main body. According to the mortar scraping device, the mortar scraping surface is arranged at the bottom of the main body, and the bottom of the mortar scraping surface is not a plane and is gradually sunken from the two ends, perpendicular to the advancing direction, of the main body to the middle of the main body, so that the upper surface of scraped mortar is in a middle convex shape; and when tiles are laid on mortar, uneven parts of the ground and uneven mortar can be filled more easily, bubbles can be discharged from inside to outside, the hollowing phenomenon is prevented, and the construction quality is ensured.
