Abstract

The invention discloses a scraper blade for a pre-leveling mechanism of an asphalt paver. The scraper blade comprises a machine frame, wherein the machine frame is of an N-shaped structure; scraper blade bodies are arranged between the side walls of the vertical portions on opposite sides of the machine frame, and sliding grooves are formed in the side walls of the vertical portions on opposite sides of the machine frame; the sliding grooves are matched with the left and right ends of the scraper blade bodies, a through hole is formed in the central of a cross beam of the machine frame, and agroove is formed in one side of the through hole; a fixing mechanism is arranged in the groove, and a rolling bearing is fixedly connected to the central of the cross beam of the machine frame; a screw rod is fixedly connected to the inner side of the rolling bearing, and a rotating disc is fixedly connected to one end of the screw rod; blind holes are formed in the centres of the upper ends of the scraper blade bodies, and threaded sleeves are fixedly connected to openings of the blind holes. According to the scraper blade, technicians can conveniently adjust the height of the scraper blade bodies and limit the adjusted blade bodies, and meanwhile, an asphalt concrete material scraped by the blade bodies can be stirred to prevent the asphalt concrete material from being too much and squeezed on the scraper blade bodies and influencing the paver to walk.

Description

technical field [0001] The invention relates to the technical field of asphalt paver, in particular to a scraper for a pre-levelling mechanism of an asphalt paver. Background technique [0002] Asphalt binder bonds the mineral aggregates into a whole, increases the strength and enhances the ability of the pavement to resist driving damage, and makes the pavement water-resistant. The asphalt materials suitable for road construction are mainly petroleum asphalt and coal asphalt. Asphalt binder improves the ability of paving aggregates to resist road damage from driving and natural factors, making the road smooth, less dusty, impermeable and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction, and asphalt paver is the most important construction machine in road construction. [0003] In the prior art, the shape of the scraper used for the pre-leveling mechanism of the asphalt paver is fixed, which is inconvenient to adjust the...
