Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a compaction wheel of a compaction machine, including an iron wheel roll at the open end of the compaction wheel and an elastic material lined on the surface of the iron wheel roll. Regarding mounting structure with materials.

[Conventional technology]

Generally, in iron wheel rolls, on the outer peripheral surface of the end of the roll,
A taper is formed over a range of several tens of mm from both ends. This is because if the taper is not formed,
This is because a slight linear locus called a so-called roller mark is left on the rolling surface on which both ends of the roll pass.
However, as shown in, for example, Japanese Patent Laid-Open No. 58-502, or as shown in FIGS. 3 and 4, an iron ring roll 11 is provided with a roller 10 having a surface lining made of an elastic material 12 such as rubber. Then, the outer peripheral surface of the end portion of the roll does not need to be formed in a tapered shape. This compaction wheel 10 with a surface lining on the iron wheel roll 11 has a synergistic effect of the centralized compaction effect and the flatness effect of the iron wheel roll 11 and the effect of enhancing the water tightness due to the kneading effect of the pneumatic tire. It is possible to improve flatness and watertightness at the same time as compaction of the bituminous mixed pavement material layer, which could not be achieved by the compaction machine.

[Problems to be solved by the device]

However, in the case of the compaction wheel 10 in which the elastic material 12 such as rubber is simply lined on the surface of the iron wheel roll 11 so as to cover the entire width of the surface layer, as shown in FIG. (A rough surface) and pebbles 15 and so on to rotate,
The elastic material 12 is easily scratched and damaged. Particularly, in the case of elastic material such as rubber, if a part of the elastic material is peeled off, the damage progresses from there, and there is a problem that the purpose of lining the elastic material cannot be finally achieved.

An object of the present invention is to solve the above problems and to provide a compaction wheel of a compaction machine in which the elastic material does not come into contact with a curb or a small stone when the compaction machine is running.

[Means for solving the problem]

As a means for achieving the above object, the present invention provides an exposed portion of the iron wheel roll on the outer peripheral surface of at least one end of the iron wheel roll, and the surface of the iron wheel roll excluding the exposed portion is made of an elastic material. The present invention proposes a compaction wheel of a compaction machine characterized by having a surface lining.

In this case, the outer peripheral surface of the exposed portion is formed in a tapered shape, and a tapered cut groove is provided toward the exposed portion side on the outer peripheral surface on the end side of the iron ring roll excluding the exposed portion. It is effective to perform surface lining so that the surface and the outer peripheral surface of the elastic material are continuous taper surfaces. Furthermore, one side in the depth direction of the cut groove is set to the other side of the tapered cut groove. It is more effective if the surface is lined by forming it at an acute angle and digging the elastic material into the cut groove.

[Action]

By adopting the above-mentioned configuration, the open end of the compaction wheel can be made of iron, and the side surface of the elastic material does not directly contact the curbstone or the pebbles accumulated on the side of the end, so that the elastic material is damaged. Less often.

〔Example〕

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a partially enlarged view of a compaction wheel showing the present invention. Also in the compaction wheel A of the compaction machine of the present invention, the surface of the iron ring roll 1 is provided with the surface lining made of the elastic material 2 such as chloroprene rubber or urethane rubber to have a uniform thickness. Then, the mounting structure of the iron wheel roll 1 on the open end side of the compaction wheel A and the elastic material 2 lined on the surface of the iron wheel roll 1 will be described. The outer peripheral surface of at least one end side of the compaction wheel A will be described. The exposed part 3 of the iron wheel roll 1
The surface of the iron ring roll 1 excluding the exposed portion 3 is provided with a surface lining made of an elastic material 2.

In this case, the outer peripheral surface of the exposed portion 3 is formed in a tapered shape, and a tapered cut groove 4 is provided toward the exposed portion 3 side on the end side surface of the iron wheel roll 1 excluding the exposed portion 3.
The exposed portion 3 and the elastic material 2 are lined in a folded shape so as to form a continuous tapered surface.

Further, one side 5 in the depth direction of the cut groove 4 is formed at an acute angle with respect to the other side of the cut groove 4 which is tapered toward the exposed portion 3 side, and the cut groove 4 is made to invade an elastic material. Has a surface lining.

With this configuration, when the rolling machine is running, the side surface of the elastic material on the open end side does not come into contact with the curb stones or pebbles and rotate, and the end portion of the iron wheel comes into contact with the side surface. It is possible to reduce the problem of damage due to damage.
Further, a tapered surface is formed on the exposed portion, and a tapered notch groove is provided toward the exposed portion on the outer peripheral surface on the end side of the iron ring roll excluding the exposed portion, and the outer peripheral surface of the exposed portion and the elastic material are provided. In the example of the compaction wheel that has been subjected to the surface lining so that the outer peripheral surface of the roll is a continuous tapered surface, a continuous tapered shape is formed from the exposed portion to the vicinity of the joint portion of the elastic material, It is possible to prevent generation of roller marks in which a slight linear locus remains on the compaction surface where both ends pass. Further, as in the embodiment, one side 5 in the depth direction of the cut groove 4 is formed at an acute angle with respect to the other side of the cut groove 4 which is tapered toward the exposed portion 3 side, and the cut groove 4 is made of an elastic material. When the elastic material 2 is made to bite into the lining and the elastic material 2 is less likely to peel off, the purpose of lining the elastic material on the iron wheel roll can be achieved. That is, it is possible to enhance the flatness and the watertightness at the same time as the compaction of the bituminous mixed pavement material layer, which cannot be achieved by the conventional compaction machine.

The present invention is not limited to the above embodiment,
It goes without saying that various modifications and embodiments can be made without departing from the idea of the invention.

[Effect of device]

As described above, according to the compacting wheel of the compacting machine of the present invention, since the side surface of the elastic material on the open end side does not directly contact the curb or the like when the compacting machine is running, it may be damaged. Problems such as breakage can be greatly improved, and the intended purpose can be achieved as a compaction wheel having an elastic material lined on the surface.

Also, since one side in the depth direction of the cut groove is formed into an inverted taper shape, the elastic material can be invaded on the surface of the iron wheel roll, making it extremely difficult to peel off.
