AI Technical Summary

Technical Problem

Existing concrete leveling equipment is insufficient in terms of adjustment flexibility and leveling effect, making it difficult to adapt to construction areas of different widths and thicknesses, resulting in low construction efficiency and uneven surfaces.

Method used

The system employs a drive-moving mechanism, an electric telescopic rod, and an adjustable flat frame. Combined with an adjusting rod and a scraping mechanism, it enables the adjustment of the width and height of the leveling roller. The scraping mechanism removes excess concrete, ensuring a smooth leveling effect.

Benefits of technology

The width and height of the leveling roller are adjustable, which can adapt to different construction areas, achieve good leveling effect, avoid excess concrete accumulation, and improve construction efficiency and flatness.

Abstract

This application discloses a concrete leveling machine, comprising: a driving and moving mechanism for driving movement; an electric telescopic rod mounted on the upper side of the driving and moving mechanism, and an adjustable flat frame mounted on the inner side of the moving end of the electric telescopic rod; an adjusting rod threadedly connected to the inner side of a first mounting frame, and a positioning block rotatably mounted on the outer side of the adjusting rod; the first mounting frame and a second mounting frame forming a sliding connection; and a scraping mechanism mounted on the lower end of the adjustable flat frame to scrape away excess concrete first. This application has at least the following advantages: by rotating the adjusting rod to drive the positioning block, the second mounting frame slides along the first mounting frame, achieving continuous adjustment of the leveling roller spacing to adapt to concrete construction surfaces of different widths; the electric telescopic rod drives the adjustable flat frame to rise and fall vertically, allowing the leveling rollers to conform to concrete layers of different thicknesses, ensuring consistent leveling results.
