DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid spraying apparatus for supplying a liquid to the surface of a tire of a tire roller to prevent the asphalt mixture from adhering, and more particularly to an uneven surface or an inclined surface such as a raised surface or a depressed surface. The present invention relates to a liquid dispersing device for a tire roller capable of uniformly ejecting a liquid to a tire surface even when rolling is performed. As the liquid for preventing the asphalt mixture from adhering to the surface of the tire, water may be used as it is, a liquid asphalt adhesion inhibitor or a substance obtained by diluting the same with water, or an oil system. May be used.

[0002]

2. Description of the Related Art As one of compaction machines used for compacting roads and the like, a plurality of (generally about 3 to 6) pneumatic tires (hereinafter, referred to as tires) are mounted around the lower part of a vehicle body. There are rollers. In order to prevent the asphalt mixture from adhering to the tire during the rolling work, this tire roller has a liquid spray pipe attached to it in contact with the tire. On the other hand, there is provided a liquid spraying device that sprays the liquid continuously or intermittently in a mist state.

FIG. 7 is a partial perspective view showing an example of a conventional tire roller liquid spraying device, and FIGS. 8A and 8B are a plan view and a side view thereof. These figures show the front wheel 2 side of the tire roller. Each of the three tires 2 ₁ , 2 ₂ , 2 ₃ has an axle frame 6 composed of a square frame parallel to the road surface and an axle frame 6. An axle 8 penetrating through the wheel 6 in parallel with the road surface is swingably supported by the yoke 5, and the yoke 5 is supported by the vehicle body 1. The upper side of the yoke 5, a predetermined position that is the tire 2 _1, 2 _2, 2 ₃ arrangement positions the liquid spray pipe 10 fitted with an injection nozzle to match the is fixedly attached to. The liquid for spraying stored in the abdomen of the vehicle body 1 is sucked / discharged by an electric pump (not shown) and supplied to the liquid spraying pipe 10 via the hose 18a.

[0004]

By the way, when the tire roller has an uneven surface due to the compaction of a roadbed or a subgrade, or when the compacted road surface is an inclined surface such as a raised surface or a depressed surface, the tire roller is moved forward and backward. The axle frame 6 supporting the front wheel 2 is swingably supported by the pin 7 on the yoke 5 in order to avoid a situation in which only one of the wheels is lifted up without contact with the other tire. And the front wheel 2
Can be tilted left and right with respect to the traveling direction of the tire roller. In this case, as shown in FIG.
Each of the tires 2 ₁ , 2 ₂ , and 2 ₃ tilts along the slope, but the liquid spray pipe 10 is connected to the vehicle body 1 side, that is, the yoke 5.
Therefore, the liquid ejected from the injection nozzle does not follow the tilt of the tire, does not uniformly spread over the tire surface, and an area where the liquid is not sprayed on _one side w1 in the width direction of the tire comes out. Further, in the side of the other w _2, will be a liquid sprayed to the side of the tire, in particular, when liquid to be sprayed were of the oil lines, tire accelerate the degradation to swell and the road surface When it reaches, there is a problem that the rolling surface is also adversely affected.

On the other hand, the inside of the yoke 5 and the tire 2₁,

That it is necessary to provide a dedicated spray nozzle
There was a problem with the assembly work.

[0006]

In order to solve the above-mentioned problems, the present invention provides a yoke mounted on a vehicle body, an axle frame swingably supported by the yoke, and an axle frame mounted on the axle frame. A liquid spraying device for a tire roller, comprising: a plurality of tires supported on an axle; and a liquid spraying pipe fixed to the axle frame and having a spray nozzle for spraying a liquid to each of the plurality of tires. did.

In this case, it is preferable that the liquid spray pipe is fixed to the axle frame via a bracket.

Further, it is more effective if the liquid spray pipe is arranged inside the yoke.

Embodiments of the present invention will be described below with reference to the drawings. 2 and 3 are an overall plan view and a side view showing an example of a tire roller liquid spraying device according to the present invention. FIG. 4 is an enlarged view of a main part of FIG. 2, and FIG. 5 is a main part of FIG. It is an enlarged view. In these figures, a front wheel 2 as a guide wheel composed of _three tires 2 ₁ , 2 ₂ , and 2 ₃ is disposed at a front portion of a vehicle body 1, and four tires 3 ₁ and 2 are provided at a rear portion. 3 _2, 3 _3, 3 a rear wheel 3 as a driving wheel constituted by ₄ is disposed.

A yoke 5 is supported by the vehicle body 1 on the front wheel 2 side so as to be pivotable about the king pin 4. An axle frame 6 consisting of a square frame is attached to the yoke 5

Although the example in which the liquid spray pipe 10 is attached to the brackets 9, 9 'raised from the top of the axle frame 6 has been described, it is only required that the pipe 10 be attached to the axle frame 6 that follows the tilt of the tire. Alternatively, it may be directly or via another member.

[0014]

As described above, according to the tire roller liquid spraying apparatus of the present invention, the liquid spraying pipe is fixed to the axle frame which is swingably supported by the yoke. The liquid can be sprayed uniformly on the surface of each tire by tilting following the tilting. Therefore, when rolling on an uneven land or an inclined surface as in a conventional liquid spraying device, an area where liquid is not sprayed on one side in the width direction of the tire comes out, or a side surface of the tire on the other side in the width direction of the tire. Can be solved. Furthermore, since the liquid is sprayed directly from the liquid spray pipe to the tire surface inside the yoke, it is possible for the yoke to hinder the ejection of the liquid to the tire located at the center of the odd number of tire configurations as in the conventional case. In addition, there is no need to take any troublesome means of providing a separate injection nozzle.
