In order to efficiently scrape off the deposits attached to the rolling wheels such as tires with the blade member of the mudguard, the blades must always be tangential to the surface of the rolling wheels against the deposits. It is required to apply force with the member.
However, if the deposit is trapped between the blade member and the rolling wheel, the scraping force is not applied to the trapped deposit. Therefore, as shown in FIG. 9, the blade member 2 is often mounted slightly inclined from the tangential direction of the rolling wheel 1 toward the center of the rolling wheel so that the force of the tangential direction component is also applied to the adhered matter. . (A), (b),
FIG. 10C is a cross-sectional view showing only the blade member of the mudguard device of FIG. 9. (A) of the same figure has shown the stationary state of the compaction wheel. (B) of the figure shows a state where the rolling wheel rotates in the direction of the arrow and the rolling machine is moving forward, and a force of a tangential component of the rolling wheel is applied to the deposit on the rolling wheel 1. This is scraped off efficiently. (C) of the figure shows a state in which the rolling machine is moving backward, and as the rolling wheel rotates, the deposit A attached to the rolling wheel is formed between the blade member 2 and the rolling wheel 1 from above. Accumulate in the sharp inner space. Then, finally, the blade member 2 is pushed up, so that the adhered substance cannot be sufficiently removed.

[0005] Since the rolling machine moves the vehicle back and forth during the rolling operation, the state of FIG. 10C is changed to the state of FIG. Although the situation is improved, it is difficult to remove the deposit once deposited after a little time. In addition, when switching from forward to reverse, the lump accumulated in the acute angled inner space formed by the blade member 2 and the compaction wheel 1 is dropped to the front side of the rear wheel by the reverse rotation, causing the compaction road surface to become rough.

On the other hand, FIG. 11 (a), (b), (c)
FIG. 2 is a cross-sectional view showing a mudguard device in which the blade member 2 is pressed perpendicularly to a tangential direction of the rolling wheel 1.
(A) of the same figure has shown the stationary state of the compaction wheel. (B) of the same figure shows a state where the rolling machine is moving forward,
(C) shows a state where the compaction machine is moving backward. Since the blade member 2 is pressed perpendicular to the tangential direction of the rolling wheel 1, the efficiency of removing the deposit is not very good, but the blade member 2 is independent of the rotating direction of the rolling wheel 1.
Acts at the same angle with respect to the attached matter, so that a certain degree of scraping performance can be expected in both forward and backward movements.
However, in order to completely prevent the deposit from entering between the blade member 2 and the rolling wheel 1, it is necessary to strongly press the blade member 2 toward the rolling wheel 1. Then, there arises a problem such as wear of the rolling wheel and the blade member. Also,
When the blade member is made of a soft material such as synthetic resin,
The blade member 2 is deformed as shown in the drawing due to the bending force from the rolling wheel and the deposits depending on the mounting angle, and the deposits easily pass between the blade member 2 and the rolling wheel 1. Further, in addition to the situation shown in FIG. 2B, in FIG. 2C, a part A ′ of the scraped off deposit accumulates on the blade member 2, and when the vehicle advances again, the front of the rear wheel is moved forward. In such a case, there is a risk that the mass may fall and roughen the compacted road surface.

As described above, in the present embodiment, regardless of whether the rolling wheel 1 is rotating in the forward direction or the reverse direction, the frictional force with the rolling wheel 1 is caused by the frictional force with the rolling wheel 1 in accordance with the direction. The two sides 2a and 2b swing at an ideal angle and stop. Thereby, the attached matter can be scraped off efficiently. In this case, since the upper portion of the blade member 2 is empty without any obstacle, the scraped-off deposits do not accumulate on the upper side of the blade member 2. As a result, it is possible to solve the problem that is likely to occur in the conventional mudguard device, in which the mass of the adhered substances drops and roughens the compacted road surface when the compacting machine is switched from backward to forward.
