Description

TECHNICAL FIELD

[0001] The utility model relates to ground cleaning machine technical field, specifically a ground cleaning machine tail scraper adjusting structure. BACKGROUND

[0002] The ground cleaning machine, also known as a floor washing machine or a floor washing vehicle, is a full-automatic cleaning equipment integrating spraying, washing and sewage recycling. It can clean hard ground and dry sewage, thereby achieving the purpose of cleaning the ground. The working principle of the ground cleaning machine is mainly based on physical friction and vacuum water suction technology. Clean water and detergent are combined and automatically flow to the brush disc of the floor washing machine. The rotating brush disc separates the dirt from the ground quickly. At the same time, the vacuum motor operates to make the sewage tank become a vacuum state. Then, the sewage is recycled to the sewage tank through the sewage suction pipe driven by the water suction plate behind the floor washing machine. Some floor washing machines also have a water scraping function, and the bottom is equipped with a scraper.

[0003] The scraper contacts the ground to clean and concentrate dust and sewage. After being used for a certain period of time, the scraper is worn out. Due to the difference in road conditions, the degree and angle of wear of each area of the scraper are different. The wear degree of one side may be greater than that of the other side, which makes the scraper cannot be used normally and can only be replaced. Moreover, the replacement frequency is also high, which increases the cleaning cost. UTILITY MODEL CONTENT
