Description
Technical field
The utility model relates to a kind of nozzle structure, especially relates to a kind of being applied on rubber-tyred roller and carries out to its tire tread the nozzle structure that fluid sprays operation, belong to rubber-tyred roller technical field.
Background technology
Rubber-tyred roller has good flexible compaction capacity, and its compaction quality is good, and can not destroy the aggregate be compacted, and is requisite compacting equipment in asphalt pavement construction; When using rubber-tyred roller compacting asphalt, in order to prevent being bonded on tire tread thus road pavement damages because of pitch, need to carry out fluid coating operation at surface of tyre;
For this reason, on April 30th, 2010, " Technology Branch of XCMG Engineering Machinery Co., Ltd. " applied for that the patent No. is the Chinese patent " rubber tyred roller and injection system " of 201010169793.1; " SANY Heavy Industry Co., Ltd " has published the signed article of " rubber-tyred roller automatic oil spout system " by name on periodical " engineering machinery " the 42nd volume in March, 2011, it is all the automation injection systems researched and developed to solve above-mentioned fluid coating problem, but the nozzle structure above in two kinds of injection systems, all have employed traditional sprinkler tip; Its project organization substantially as shown in Figure 4, is made up of pipe clamp 101, sprayer body 102, gland 103 and nozzle 104; Above-mentioned nozzle structure is for this medium designs of water, and because oil viscosity is greater than the viscosity of water, the fluid sprayed with this shower nozzle with column injection, does not reach the object to tire tread uniform application usually; Simultaneously because the internal resistance of oil is larger, pressure in pipeline is also just very large, the oil-out diameter of nozzle can make oil-out diameter become very soon greatly due to the impact of high pressure, causes the fluid diffusion tendency of ejection poorer, thus makes spraying effect can not meet the needs of construction.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide that a kind of structure is simple, easy to maintenance, spraying evenly and the good rubber-tyred roller tire tread oil spout nozzle structure of shower nozzle spraying effect uniformity.
The purpose of this utility model is achieved in that
A kind of rubber-tyred roller tire tread oil spout nozzle structure, described nozzle structure includes sprayer body, described sprayer body center is provided with oil duct, there is pad one end of described sprayer body by nozzle cap pressing, the center of described pad is provided with centre bore, this centre bore is connected with the oil duct of sprayer body, described pad is provided with a fan-shaped gap, and this fan-shaped gap is connected with centre bore.
A kind of rubber-tyred roller tire tread of the utility model oil spout nozzle structure, the described center line of fan-shaped gap and the center line of centre bore coincide, the center line of the centre bore of described pad and the distance of tire are D, the segment angle of described fan-shaped gap is α, the tread width of described tire is that L(tread width is consistent with the oil film width sprayed through fan-shaped gap), it meets L=2D × tan(α/2).
A kind of rubber-tyred roller tire tread of the utility model fuel injecting method, high-voltage oil liquid enters in the fan-shaped gap of pad through the oil duct of sprayer body and forms high-voltage oil liquid, outwards sprayed with sector by fan-shaped gap subsequently, due to the reduction of pressure in ejection process, fluid is evenly sprayed on tire tread along with density reduction formation is vaporific.
Compared with prior art, the beneficial effects of the utility model are:
Simple, easy to maintenance, each part of structure of the present utility model makes easily; Once occur that shower nozzle is because of the dirty blocking fan section of fluid or damage pad, the screw that can come loose cleaning or replacing pad; The utility model adapts to wide to the viscosity of oil product simultaneously, the fluid of different viscosities is realized to the optimum state of oil atomizing by the pad changing different-thickness, thus make its spraying more even, and said structure is not fragile, thus making in whole spraying process, the uniformity of spraying effect is good; In addition, after the utility model installs sector shaped washer additional between sprayer body and nozzle cap, outwards spray with the fan-shaped oil film of high pressure formed, and by the distance of the segment angle that adjusts fan-shaped gap and itself and tire tread, oil film width is regulated, make it consistent with the width of tire tread, ensure that the effect of spraying.

Detailed description of the invention
See Fig. 1 ~ 3, a kind of rubber-tyred roller tire tread oil spout nozzle structure that the utility model relates to and fuel injecting method thereof, described nozzle structure includes sprayer body 1, described sprayer body 1 center is provided with oil duct, there is pad 3 one end of described sprayer body 1 by nozzle cap 2 pressing, screw 4 on described nozzle cap 2 hammers in sprayer body 1 through pad 3, thus make sprayer body 1, pad 3 and nozzle cap 2 tightly press together successively, the center of described pad 3 is provided with centre bore 3.1, this centre bore 3.1 is connected with the oil duct of sprayer body 1, described pad 3 is provided with a fan-shaped gap 3.2, and this fan-shaped gap 3.2 is connected (preferred with centre bore 3.1, the center line of above-mentioned fan-shaped gap 3.2 and the center line of centre bore 3.1 coincide), thus make fluid through oil duct, centre bore 3.1 and the fan-shaped gap 3.2 of pad 3 spray to road roller wheel tyre surface, when fluid leaves fan-shaped gap 3.2 under High Pressure, its shape continues the sector before keeping ejection, and thickness direction makes the thickness of sector become rapidly large due to the rapid reduction of ambient pressure, makes fluid density reduce and become vaporific, and be sprayed on oil film width on tire tread and shower nozzle and be associated to the distance of tire tread and segment angle size, the center line of the centre bore 3.1 of above-mentioned pad 3 and the distance of tire are D, and the segment angle of above-mentioned fan-shaped gap 3.2 is α, so now spray width L=2D × tan(α/2 of the oil film on tire tread), this oil film width is the tread width of tire,
A kind of rubber-tyred roller tire tread fuel injecting method, high-voltage oil liquid enters in the fan-shaped gap 3.2 of pad 3 through the oil duct of sprayer body 1 and forms high-voltage oil liquid, outwards sprayed with sector by fan-shaped gap 3.2 subsequently, due to the reduction of pressure in ejection process, fluid is evenly sprayed on tire tread along with density reduction formation is vaporific;
In addition: it should be noted that above-mentioned detailed description of the invention is only a prioritization scheme of this patent, any change that those skilled in the art does according to above-mentioned design or improvement, all within the protection domain of this patent.
