Description
Technical field
The present invention relates to a kind of feeding device and using method thereof, particularly relate to a kind of road-surface joint-grouting machine feeding device and be somebody's turn to do
The using method of device.
Background technology
Processing the crack on road surface at present, usual employing pouring machine is inserting crack after base joint grouting glue heating, and the mode heated
Substantially having three kinds, the first does not has heater, directly makes base joint grouting glue flow out, due to conveying pipeline length relatively by material pump extruding
Long, when base joint grouting glue flows to nozzle, temperature is not the most the highest, and the base joint grouting glue in nozzle will slowly solidify, and causes nozzle to block up
Plug；The second, is put into melt case by nozzle, is heated by the steam in case, although this method compares preferably, but adds
There is stationary temperature in labor intensity, and use cannot ensure nozzle, affect cementation of fissures quality and efficiency；The third, in spray
Being wound around heater strip on mouth, heater strip is remained high temperature by innermost layer gradually outer layers heat conduction, innermost layer temperature, easily makes interior
Layer heater strip is aging, thus decreases the service life of nozzle.
Existing pouring machine nozzle angle is more fixing and does not has suitable angle of bend, is merely capable of keeping a side
To carrying out the cementation of fissures, by artificial dilatory advance, and feed liquid cannot be carried out floating by nozzle itself so that the complete way of escape of the cementation of fissures
Face is uneven, affects attractive in appearance.The nozzle that cannot rotate is for irregular crack and small-sized grid crack inapplicable.
Existing pouring machine is that sizing material is imported conveying pipeline by the hydraulic means by self, then relies on the stream of sizing material self
Dynamic property fills crack, but for deeper crack, not only elapsed time is longer but also the sizing material of depths, crack is filled uneven.
And the process of tailing after the cementation of fissures, directly clean conveying pipeline, significantly waste the sizing material in conveying pipeline, and clean the most thorough.
Summary of the invention
The technical problem that present invention mainly solves is to provide the use of a kind of road-surface joint-grouting machine feeding device and this device thereof
Method, can carry out post bake to the sizing material flowed out at nozzle discharge hole, it is ensured that the quality of cementation of fissures sizing material, again can limit stream slurry
Limit is pressed, and improves cementation of fissures efficiency, meanwhile, uses this method to carry out the cementation of fissures work of pouring machine feeding device, rapid operation, the cementation of fissures
