Description

Technical Field

[0001] The utility model relates to the field of ground cleaning equipment, in particular to a base cleaning device for ground construction. Background Art

[0002] Cleaning the base layer during ground construction is a crucial step. In order to make the ground surface smooth and facilitate the subsequent construction of the leveling layer, scraping, compacting and grinding can be used for leveling. Scraping is to use a scraper or mechanical equipment to level the height difference of the ground surface; compaction is to use heavy equipment such as rollers to compact the ground to increase the density and homogeneity of the ground; grinding is to use grinding equipment to perform leveling work.

[0003] When the ground is polished and leveled, a lot of dust will be generated. The dust will be scattered at the polishing position and inhaled by the operator, which can easily affect the operator's health. At the same time, the dust will also affect the line of sight, thereby affecting the accuracy of the polishing operation and affecting the construction. Therefore, a device is urgently needed to solve the above problems. Utility Model Content
