The rotary rotor 5 is rotated so that the blade portion 9 plows up the mud in the old ridge 4 or the like and raises it.

Reference numeral 10 denotes a side cover member, and the side cover member 10 is provided so as to be vertically movable along the upper surface of the ridge 4.

Reference numeral 11 denotes a vibrating body. In this case, the vibrating body 11 includes an upper plate member 11a slidingly contacting the upper surface of the ridge and a side plate member 1 slidingly contacting the sloped surface of the ridge.
1b and vertical section according to the ridge It is formed in a shape.

Reference numeral 12 denotes a support mechanism. In this case, two swing links 13 are pivotally mounted on the machine frame 3, and a mounting member 14 is pivotally mounted on the tip of the swing link 13, and the mounting member 14 is buffered. Mechanism 1
5. In this case, the vibrating body 11 is attached via the slide shaft 16 and the buffer spring 17.

Reference numeral 18 denotes a vibrating mechanism. In this case, a vibrating member 20 in which an eccentric weight body 19 is rotatably mounted is attached to the vibrating body 11, a pulley 22 is fixed to a support shaft 21 on the eccentric weight body 19, and a pulley is attached to the main shaft 8. 23 is fixed, and the belt 24 is attached to the pulley 23.
And a tension roller 26 that is pressed against the outer surface of the belt 24 by the pressing spring 25 to remove the slack of the belt 24 is swingably provided, and the support shaft 21 is rotated by the rotation of the main shaft 8.
The vibrating body 11 is vibrated by the action of the eccentric weight body 19.

27 is a flexible member, in this case the cover member 6
Two mounting frames 28 are attached to the rear surface in the direction of travel of the mounting frame 28, and a vertical shaft 29 is provided on the mounting frame 28 so as to be vertically movable by rollers inside the mounting frame 28.
A mounting plate 30 covering the rear opening is attached, and the mounting plate 3
The flexible member 27 is fixed to 0, and the vertical shaft 29 is pushed up by the push-up spring 31 until the stopper 32 of the vertical shaft 29 contacts the mounting frame 28, and the loose lower portion 33 of the flexible member 27 is vibrated. It is connected to the rear end portion of the vibrating body 11 via a mounting bolt 34 below.

In this case, rubber is used as the flexible member 27, but flexible resin or leather may be used, and sponge, bristles or the like may be attached to the inner surface of the flexible member 27 on the ridge side.

Since the first embodiment has the above-mentioned configuration, when the traveling machine body 1 travels along the old ridge 4, the rotary rotor 5 rotates and the old ridge 4 is rotated.
The mud is piled up on the old ridge 4 while plowing the inside and the like, the cover member 6 can prevent the mud from scattering outward, and the embankment efficiency can be improved. On the other hand, the vibration mechanism 18 drives the embankment to vibrate the body 11. Since the vibrating body 11 has a shape adapted to the upper surface of the ridge and one side surface of the ridge, the upper surface of the ridge and the inclined surface of the ridge are tightened at the same time.
Of the loose portion 33 because the flexible member 27 is connected to the vibrating body 11 while preventing the mud from scattering backward in the traveling direction of
Can be prevented from being turned up by the unevenness of the embankment and the scattered mud, and the embankment efficiency can be further improved, whereby the ridge 4 can be firmly tightened, and a new ridge that is efficient and robust can be obtained.

In this case, since the flexible member 27 is located on the inner side of the vibrating body 11 on the ridge side, it has a mud-removing action, and reliably prevents the mud from adhering to the sliding contact surface of the vibrating body 11, thus strongly embankment. The flexible lower part 33 of the flexible member 27 can be
Therefore, it is possible to prevent the loose lower part 33 of the flexible member 27 from fluttering due to the vibration action of the vibrating body 11.

The second embodiment of FIG. 4 shows another example of the support mechanism 12 for the vibrating body 11. In this case, four guide rollers 35 are provided in the machine frame 3, and a movable body 36 is slidably provided by the guide rollers 35. The vibrator 11 is attached to the moving body 36 via the buffer mechanism 15, and the stopper member 37 of the moving body 36 is attached.
Is provided in the machine casing 3.

In the third embodiment shown in FIG. 5, the movable body 36 of the second embodiment is used as a fixing member 38, and the fixing member 38 is fixed to the machine frame 3 with bolts 39, and a hydraulic vibrator 40 is used as the support mechanism 12. Used, hydraulic vibrator 40
Is connected to a hydraulic pump (not shown) via a pressure oil pipe 41.
