The towing vehicle 10 according to the present invention may include a power generating device such as an internal combustion engine, an external combustion engine, or a motor to pull the plurality of compaction rollers 30 forward, backward, or turn left and right.

The upper support plate 20 is connected to the connecting device 40 and is pulled by the towing vehicle 10 and is connected to the rotary shaft 31 of the plurality of compaction rollers 30 through a plurality of connection supports 21 So that the plurality of compaction rollers 30 are pulled by the towing vehicle 10.

The plurality of compaction rollers 30 are cylindrical rollers made of heavy materials such as iron or steel and rotate around a rotation axis 31 perpendicular to the traveling direction of the towing vehicle 10. The plurality of compaction rollers 30 are provided with a vibration device 50 in order to increase the compaction efficiency by generating vibration while being pulled by the towing vehicle 10.

Fig. 3 is a partial cross-sectional view of a left vibrating device installed on a compaction roller according to the present invention.

3, the interior of the compaction roller 30 is the same as an empty hollow drum, and a hollow cylindrical tube made of metal such as steel or iron or a rectangular parallelepiped The body can be attached by a coupling means such as a bolt.

At the left end of the compaction roller 30, a cylindrical rotating shaft 31 is formed by extending a certain length D1 toward the inside. The inside and outside of the compaction roller 30 can communicate with each other through the rotation shaft 31 because the rotation shaft 31 has a through-hole clearance structure.

Although the left end portion of the compaction roller 30 and the rotation support shaft tube 22 have been described, the left and right sides have the same configuration. In order to avoid the complexity of the description, the description of the right end portion and the rotation support shaft tube is omitted, The same applies to the right side.

A rotary support shaft tube 22 formed integrally with the connection support 21 by a predetermined length D2 is inserted into the rotary shaft 31 and the compaction roller 30 is pulled by the towing vehicle 10, (31).

The right end of the rotation supporting shaft tube 22 facing the inside of the compaction roller 30 is opened and the compaction roller 30 is closed. The rotation of the compaction roller 30 is supported by the rotation of the compaction roller 30 without rotating.

The vibration device 50 according to the present invention includes an electric motor 51 fixedly installed inside a rotary support shaft 22 as shown in FIG. An eccentric oscillating body 52 coupled to a rotating shaft 51a of the motor 51; And coupling means (53) for fixing the electric motor (51) inside the rotary support shaft tube (22).

A wire hole 22a is formed in the side surface of the rotary support shaft tube 22 so that the electric wire 23 is inserted and connected to the electric wire connection terminal 51b of the electric motor 51, And the like.

The electric motor 51 may use a hydraulic motor, and the hydraulic pressure may be supplied to the hydraulic motor by connecting the hydraulic pipe through the electric wire hole 22a.

4A is a partial cross-sectional view showing a state in which the vibration device is assembled to the compaction roller according to the present invention, and FIG. 4B is a cross-sectional view of the vibration device according to the present invention in which the other end of the rotation shaft of the motor is supported by a rotation axis support An embodiment is shown.

Since the central axis X2 of the motor 51 is provided at the end of the rotating shaft 51a but the center axis X2 of the motor 51 is not coincident with the rotating shaft 51a and is connected to the rotating shaft 51a The eccentric oscillating body 52 is eccentrically centered about the rotating shaft 51a and revolves to generate vibration.

The eccentric oscillating body 52 is disposed to be eccentrically downwardly biased in such a manner that the center axis X2 of the eccentric oscillating body 52 does not coincide with the rotational axis 51a of the motor 51 so that vibration can be easily generated at the time of rotation. Therefore, when the rotary shaft 51a of the motor 51 rotates, the eccentric vibrating body 52 is biased to one side so that the centrifugal force is unbalanced to generate vibration.

Further, the eccentric oscillator 52 is formed so that the lower half of the eccentric oscillator 52 is larger in weight than the upper half of the eccentric oscillator 52, and the center G of the eccentric oscillator 52 is located at the lower half of the center axis X2 So as to cause the vibration to occur more largely.

Since the right end of the rotary shaft 51a is in an idle state when the rotary shaft 51a of the motor 51 rotates and the eccentric rotary body 52 rotates, The durability of the motor 51 may be reduced as it is transmitted to the motor 51. Therefore, the rotation shaft support 60 supporting the right end of the rotation shaft 51a may be installed as shown in FIG.

The rotary shaft support 60 is fixed to the inside of the roller drum 30 by fastening means such as welding or bolt at its both ends and supports vertexes of a straight shape, a cross shape or a hexagonal shape as shown in FIGS. 5A to 5C And a hexagonal support formed along the diagonal line of the hexagonal shape.

The vibration generated in the eccentric vibrating body 52 is directly transmitted to the roller drum 30 via the rotary shaft 51a by the rotary shaft supporter 60 so that the vibration efficiency is increased and the vibration is transmitted to the electric motor 51 The cause of the failure of the motor 51 can be prevented.

Fig. 6 shows an embodiment of a vibration device in which an eccentric vibrating body according to the present invention is installed inside a roller drum and a rotational force of a motor is transmitted using a pulley.

Therefore, the eccentric oscillating body 52 is rotated and eccentrically rotated by the rotation of the driven pulley 54, thereby generating vibration. Since the vibration of the eccentric vibrating body 52 is generated in the vertical direction, the roller drum 30 also oscillates in the up-and-down direction to transmit vibration to the bottom of the compaction so that the soil, asphalt, and cement concrete So that the surface can be evened and the density of the particles forming the surface can be increased.

In another embodiment, the driving pulley 53 and the driven pulleys are sprockets. The driving belt 55 is formed of a chain. The driving sprocket is rotated by the rotational force generated by the motor 51, and the rotational force of the driving sprocket is transmitted to the driven sprocket It is well known that the eccentric oscillating body 52 is rotated to generate vibration.
