The interlocking rod body 4 has a plurality of pin holes, and the first receiving pin 8 and the second receiving pin 9 are detachably attached to the pin holes selected from the plurality of pin holes. A cylindrical metal first spring 11 is disposed in a compressed state between the first receiving pin 8 and one axial end of the cylindrical support 7 on the outer peripheral side of the interlocking rod 4. A cylindrical metal second spring 12 is disposed in a compressed state between the second receiving pin 9 and the other axial end of the cylindrical support 7 on the outer peripheral side of the body 4.

For example, when the cutting claw 6a of the pretreatment means 6 hits a hard object such as a stone located on the upper surface of the main fence during the glazing operation, the pretreatment means 6 moves upward so that the cutting claw 6a is not damaged. To do. When the pre-processing means 6 moves up, the interlocking rod 4 is interlocked and the first spring 11 is compressed. When the cutting claw 6a is separated from the hard object, the pretreatment means 6 is moved down beyond the original position by the urging force of the first spring 11, and the second spring 12 is now compressed. Thus, the first spring 11 and the second spring 12 are alternately compressed, and the pretreatment means 6 vibrates up and down until both the springs 11 and 12 are balanced.

Compressed in the direction. At this time, the anti-vibration rubber 64 is separated from the other axial end of the cylindrical support 55.

  Then, when the cutting pawl 50 of the pretreatment means 43 is separated from the hard object, the pretreatment means 43 is moved down beyond the original position by the urging force of the coil spring 63, and the vibration isolating rubber 64 is now received by the second vibration receiving rubber 64. It is sandwiched between the body 62 and the other axial end of the cylindrical support 55 and is slightly compressed in the axial direction. Thus, the coil spring 63 and the vibration isolating rubber 64 are alternately compressed, and the pretreatment means 43 vibrates up and down until the coil spring 63 and the vibration isolating rubber 64 are balanced.

  As shown in FIGS. 4A and 4B, the configuration using the coil spring 63 and the anti-vibration rubber 64 is more advanced than the conventional configuration using the first spring 11 and the second spring 12. The damping of the vertical vibration of the processing means 43 is accelerated.

  As described above, according to the plastering machine 21, the coil spring 63 disposed on the outer periphery of the interlocking rod 53 and positioned between the first receiver 61 and one end of the cylindrical support 55 in the axial direction, and the interlocking rod 53 is disposed between the second receiver 62 and the other axial end of the cylindrical support 55 and is provided with a vibration-proof rubber 64 that is less elastically deformed than the coil spring 63. The vertical vibration of the processing means 43 does not continue for a long time, and the upper surface of the main fence can be sufficiently cut by the pre-processing means 43. Therefore, the adhesion between the upper surface of the main fence and the embankment is improved and it is hard to collapse. You can get Xinjiang.

  Further, since it has a vibration damping effect while absorbing shocks such as stones, vibration of the entire coater 21 can be suppressed, and damage to the components of the coater 21 can be prevented.
