Description

Technical Field

[0001] The present invention relates to the technical field of concrete leveling, and particularly to an automatic leveling machine. Background Art

[0002] Home decoration "materializes" various situations of life into the room. Generally, the room design has been completed when purchasing, and major adjustments cannot be made. Therefore, the only thing that can be done is decoration. During the decoration process, when leveling the ground, concrete is required to level the ground.

[0003] In the existing industry leveling machine technology, when leveling concrete, it is mainly operated by manual scraping or large machinery. The operability is poor, and the accuracy is within the error range of plus or minus 10 millimeters. For the demand of laying floor tiles and wooden floors in the home decoration field, the ground accuracy is higher than that in the construction conditions outside the home decoration, and the required horizontal accuracy is within 3 millimeters. Therefore, there is a need for a leveling device with higher accuracy in the home decoration field to meet the market demand for high-precision operations in small spaces. Summary of the Invention
