A kind of asphalt seam filling machine for pavement repair

Abstract

The invention relates to the technical field of pavement maintenance equipment, and discloses an asphalt seam filling machine for pavement repair. A universal wheel is movably connected, a fuel tank is fixedly connected to one side of the top end of the vehicle plate, an extraction pump is fixedly connected to the other side of the top end of the vehicle plate, and a hot melt gun is fixedly connected to one side of the top end of the extraction pump , the other side of the top end of the extraction pump is fixedly connected with one end of the extraction pipe. In the present invention, the solid sealant is put in the middle of the heating box through the feeding pipe, and the heat transfer of the heat-conducting oil to the sealant is enhanced by the heat-conducting device, the melting speed of the sealant is increased, and the fuel waste is reduced. The height of the liquid level of the heat-conducting oil is continuously rising, and it is consistent with the height of the sealant, which is conducive to the heat preservation and heating of the sealant and avoids the heat waste of the heat-conducting oil.

Description

technical field [0001] The invention relates to the technical field of pavement maintenance equipment, in particular to an asphalt seam filling machine for pavement repair. Background technique [0002] With the development of traffic roads, asphalt pavement has become the mainstream form of today's roads, but as the use time of asphalt pavement increases, the phenomenon of pavement cracking often occurs. It is a kind of equipment that hot melts the sealant and pours it into the crack through a glue gun to repair the crack. It is usually used in conjunction with a slotting machine and a hair dryer. [0003] However, there are also some defects in the use of the asphalt joint filling machine: First, the sealant used in the asphalt joint filling machine needs to be melted into a liquid before use, but this heating process takes 40 to 50 minutes, and the melting time is too long. Second, when the sealant is used on the bottom, there is often a small amount of sealant that cann...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing asphalt joint filling machine proposed in the background technology, the present invention provides an asphalt joint filling machine for road surface repair, which has the function of lifting the bottom of the heating box when the sealant is not melted and is almost used up. , achieve the advantages of improving the heating effect, easily absorbing the sealant, solving the problem of waste of resources, and solving the technical problems raised in the above-mentioned background technology
