〔The invention's effect〕

Since the present invention is configured as described above, it has the following operational effects.

The vibration device with a ridge plate is swingably supported on the body by a parallelogram-shaped swing link mechanism formed by a swing plate, a swing arm and an arm plate, and swings. The moving plate not only swings up and down with respect to the support shaft, but also allows the swinging plate to be slightly but not in the front and rear direction perpendicular to the plate surface. The levee action will be performed well.

In addition, the vibration device equipped with a ridge plate has a spring mechanism that acts to constantly lift the vibration device between the support punch mounted on the upper part of the fuselage and the upper part of the vibration device. Vibration-type ridge that makes a fine adjustment according to the unevenness on the upper surface of the ridge, and receives a buffering effect due to the swinging motion in the diagonal up and down direction and the action that does not move back and forth, and ensures the ridge action by the vibration action of the ridge board. It becomes a ridge board holding device in the machine.

The invention according to claim 2 wherein a swing plate and a swing arm are arranged on an arm plate supporting the vibration device to constitute a parallelogram link mechanism, thereby securely supporting the heavy ridge plate with the vibration device and simultaneously forming the ridge surface. Improve vibration leveling.

Thus, a spring plate in which a force for continuous winding is applied is provided between the spring plate winding unit provided on the support punch mounted on the upper part of the machine body and the spring plate winding unit provided on the upper part of the vibration device. For example, even if the ridge board with a vibration device weighs about 25 kg, even if the force for stretching the spring plate of the leaf spring buffer device is about 10 kg, the ridge board with a vibration device is used. The load is reduced to about 15 kg and the cushioning effect is reduced, so that the ridge board holding device of the vibration type ridge board can be durably suspended and held with the vibration device.
