Description
Technical field
The present invention relates to a kind of feeding device and its application method, more particularly to a kind of road-surface joint-grouting machine feeding device and
The application method of its device.
Background technology
The crack on processing road surface, generally use pouring machine insert crack at present after base joint grouting glue is heated, and the mode heated
Substantially have three kinds, the first does not have heater, directly by expect pump extruding flow out base joint grouting glue, due to conveying length of tube compared with
Long, when base joint grouting glue flows to nozzle, temperature has not been too high, and the base joint grouting glue in nozzle will slowly solidify, and cause nozzle to block up
Plug；Second, nozzle is put into melt case, heated by the hot gas in case, although this method compares preferably, but add
Labor intensity, and cannot ensure there is stationary temperature in nozzle in, influence cementation of fissures quality and efficiency；The third, is spraying
Heater strip is wound on mouth, heater strip remains high temperature by the gradual outer layers heat conduction of innermost layer, innermost layer temperature, easily made most interior
Layer heater strip aging, so as to reduce the service life of nozzle.
Existing pouring machine nozzle angle is more fixed and without suitable angle of bend, is merely capable of keeping a side
To the cementation of fissures is carried out, by artificial dilatory advance, and nozzle in itself can not be floating to feed liquid progress so that the cementation of fissures finishes the way of escape
Face is uneven, influences attractive in appearance.The nozzle that can not be rotated is for irregular crack and small-sized grid crack and does not apply to.
Existing pouring machine is that sizing material is imported into conveying pipeline by the hydraulic means of itself, then by the stream of sizing material itself
Dynamic property filling crack, but for deeper crack, not only elapsed time is longer but also the filling of the sizing material of crack depths is uneven.
And after the cementation of fissures tailing processing, directly clean conveying pipeline, waste the sizing material in conveying pipeline significantly, and clean not thorough.
The content of the invention
The present invention solves the technical problem of the use for providing a kind of road-surface joint-grouting machine feeding device and its device
Method, reheating can be carried out to the sizing material of outflow at nozzle discharge hole, ensure the quality of cementation of fissures sizing material, the enough side stream slurries of and can
Side is pressed, and improves cementation of fissures efficiency, meanwhile, the cementation of fissures that pouring machine feeding device is carried out using this method is worked, rapid operation, the cementation of fissures
Efficiency high, repetition process are few, effectively reduce the labor intensity of operating personnel, are worthy of popularization.
In order to solve the above technical problems, one aspect of the present invention is：A kind of road-surface joint-grouting machine conveying is provided
Device, including conveying pipeline and nozzle, the nozzle are connected to conveying pipeline one end by fixing bolt, and the port of export of the nozzle connects
