Problems solved by technology

But at the turning of the high-grade road surface, not only the road surface is required to be flat, but also a certain angle between the road surface and the horizontal surface is required, so as to ensure that the car is stable during driving. Some road scrapers can't do it

Abstract

The invention discloses a pavement leveling machine. A rectangular box is arranged as a rack, a plurality of rotary scraper assemblies are movably mounted at the corners of the bottom end of the rackthrough linear bearing pairs to level the ground, and a lifting air cylinder is mounted at the top end of each rotary scraper assembly. When a certain area needs to be subjected to key scraping, the lifting air cylinders at the top ends of the rotary scraper assemblies extend forwards to push the current rotary scraper assemblies to scrape the ground, and in the whole process, a horizontal gyroscope mounted at the top end of the rack records horizontal data all the time; and when the rack is horizontal or reaches set angle data, a control module mounted at the top end of the rack is controlledthrough a shunt electromagnetic valve, a high-pressure air pump inflates each lifting air cylinder, thus the lifting air cylinders stop pushing the rotary scraper assemblies to scrape the ground, automatic control is achieved, the functional defects of an existing pavement leveling machine are overcome, and the good practical value is achieved.

Description

technical field [0001] The invention relates to a road construction machine, in particular to a road surface scraper. Background technique [0002] Road engineering refers to an applied science and technology engaged in road planning, survey, design, construction, maintenance, etc. It is a branch of civil engineering. Road usually refers to the general designation of all kinds of roads that serve for land transportation and pass through various motor vehicles, human and animal drawn vehicles, pack animals and pedestrians. According to the nature of use, roads are divided into urban roads, highways, Factory mine road , rural road road , forest road Wait. urban expressway Expressways and highways are dedicated roads for cars traveling at high speeds with controlled traffic access. [0003] The current road has been gradually upgraded from the initial simple road surface to gravel road surface, cement road surface, asphalt road surface to the latest plastic road surf...
