BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a concrete finisher according to an embodiment of the present invention.

FIG. 1 is a plan view showing an embodiment of a vibration compaction machine according to the present invention, FIG. 2 (a) is an enlarged plan view of a main part of the vibration compaction machine in FIG. 1, and FIG. ) Is the front view, FIG.
3C is a side view of the same, and FIG. 3 is a partially cutaway front view showing an example of the vibrator in FIG.

FIG. 1 shows a vibration compaction machine (hereinafter simply referred to as compaction machine) 1, which is provided in a concrete finisher as shown in FIG.

This compacting machine 1 is composed of three parts, a central part and both ends. The central part is composed of four vibration units 2 and both ends are composed of one vibration unit 3 respectively. Have been. Excitation unit 3 at both ends
Looks larger than the vibration unit 2 in the center part, but merely illustrates an example in which the vibration frame 5 is made longer than the vibration frame 4 in the center part in order to conform to the width dimension of the concrete finisher. is there. Of course, the lengths of all the vibrating units may be the same according to the width direction dimensions of the concrete finisher, or the lengths may be mixed in other combinations. Further, the vibrator 6 of the same size is installed on each of the vibration frames 4 and 5, but is not limited to the same size. Or a smaller one may be installed.

The direction of arrow A in the figure is the front of the concrete finisher.

FIG. 2 is a three-view drawing showing the details of the vibration unit 2. Reference numeral 6 denotes a vibrator, which is fixed to the upper surface of the vibration frame 4. The vibration frame 4 (the vibration frame 5 is also the same and is represented by reference numeral 4) is shown in FIG.
As is clear from (c), it is a hollow beam-shaped member formed of an iron plate so that its cross section has a substantially wedge-shaped pentagonal shape. Reinforcing ribs 7 are formed inside. Vibration is applied to the vibrating frame 4 by the operation of the vibrator 6, and the vibrating frame 4 repeatedly hits the concrete surface on its lower surface 4a.

Reference numeral 8 denotes a hydraulic motor for rotating the vibrator 6, and one hydraulic motor is provided for one vibrator 6.

Reference numeral 9 denotes a support frame extending downward from a concrete finisher main body (not shown), and the whole of the vibration unit 2 is suspended therethrough via a vibration-proof rubber member 10. . Specifically, the first support bracket 11 fixed on the upper surface of the vibration frame 4
a, the second support bracket 11b is fixed to the second support bracket 11b, the anti-vibration rubber member 10 is fixed to the second support bracket 11b, and the fixing member 12 for fixing the anti-vibration rubber member 10 and the support frame 9 are fixed. The entire vibration unit 2 is fixed to the support frame 9. The vibrating units 3 at both ends are also suspended from the concrete finisher body in the same manner.

In this embodiment, the first support bracket 11a
Are fixed to the upper surface of the vibration frame 4 by welding, and the first support bracket 11a and the second support bracket 1
1b, the fixing of the support frame 9 and the fixing member 12, the fixing of the anti-vibration rubber member 10 and the second support bracket 11b, and the fixing of the anti-vibration rubber member 10 and the fixing member 12 are performed by bolting. However, the present invention is not particularly limited to such means, and other known means may be used. In addition, the vibration-proof member is not limited to the vibration-proof rubber, and the same effect can be obtained by using, for example, a leaf spring or a coil spring.

As described above, since the vibrating units 2 and 3 are separately suspended from the concrete finisher main body, there is no need to align the vibrating units (aligning the shafts of the vibrator 6). .

Then, for example, the gap between the vibrating units 2 at the center (specifically, the gap between the vibrating frames)
Is ideally zero, but has no effect on the pavement surface if it is about 20-30 mm or less.

FIG. 3 shows the vibrator 6 in detail. Reference numeral 13 denotes a rotor, and both end support shafts 15, 16 are rotatably supported on both end walls of the housing. The rotor 13 is provided at its center with both ends supporting shafts 15 and 16.
And has a mass lump 13a eccentric from. Therefore,
When the rotor 13 rotates, the housing 1 is moved from the shafts 15 at both ends.
Vibration is transmitted to the vibration frame 4 (FIG. 2) through the vibration frame 4.

Reference numeral 17 denotes a bearing for supporting the both-end support shaft 15. Reference numeral 18 denotes an air bleeder, which is also used to inject lubricating oil into the housing 14.

Numeral 8 denotes the hydraulic motor for rotating the rotor 13, whose output shaft 8a is connected to the coupling 1
By 9, it is connected to a connection shaft 20 protruding from the right support shaft 15 of the rotor 13. The right support shaft 15, the connection shaft 20, the coupling 19, and the output shaft 8a of the hydraulic motor are all covered by a cylindrical housing 21 that is continuous with the housing 14 of the vibrator and the housing of the hydraulic motor. Of course, the housing 21 is not limited to a cylindrical shape, and may be a square tube or the like as appropriate.

With this configuration, all the rotating members of the vibration unit 2 are not exposed to the outside, and as a result,
Wind noise due to rotation does not occur, and thus noise is greatly reduced. It has been found that the noise in the experimental example is about 95 dB (A) in the conventional concrete finisher having almost the same output, but is reduced to about 85 dB (A) in the above embodiment.

[0030]

According to the present invention, it is easy to reduce noise. Furthermore, the complicated adjustment of the pavement width is facilitated by eliminating the need for a troublesome work of aligning the shaker and making the shaker a small unit.
