Problems solved by technology

[0002] Cement concrete pavements exist in large quantities in the form of airport runways, tunnel pavements, and heavy-duty roads. Many cement concrete pavements have not yet broken, but the anti-skid performance decays too quickly, and the flatness becomes poor. How to save costs , how to continue to play its advantages in places where cement concrete pavement has to be used is a problem that is widely studied nowadays
[0003] Milling teeth, also known as road teeth and milling cutters, are one of the core components of road milling machines. At present, milling teeth are mostly made of hard alloy, but they will be damaged due to severe friction during road milling. It will cause severe wear, short life and frequent replacement, which will cause many adverse effects such as delaying the construction period and increasing repair costs.

Abstract

The invention provides a diamond milling tooth for a pavement longitudinal milling machine. The diamond milling tooth mainly comprises a wheel shaft (5) and a plurality of saw blades with the same size, wherein the saw blade comprises an inner ring steel sheet (2) and a diamond circular sheet (1), and the outer circle edge of the inner ring steel sheet (2) and the inner circle edge of the diamondcircular sheet (1) are bonded through a bonding agent; and the inner ring steel sheet (2) is fixedly sleeved on the wheel shaft (5). The diamond milling tooth for the pavement longitudinal milling machine has good applicability in cement concrete pavement surface layer removing and repairing, slab staggering can be effectively removed, pavement flatness is recovered, the replacement frequency of the milling tooth is reduced, and the pavement milling quality is improved.
