PROBLEM TO BE SOLVED: To provide a ridge forming machine that has vibration absorption and damping effect.SOLUTION: In a ridge forming machine 11, an embankment unit 31 is vertically turnable by an excavation rotor vertical turning link mechanism 51. The excavation rotor vertical turning link mechanism 51 has: a first link 61 turnably connected with a machine body frame 21 and extended toward a rear; a second link 71 turnably connected with an upper part of a machine frame 12 and the rear end of the first link 61, and axially constituted of elastic flexible means 72; and a third link 81 connected turnably slidably to the first link 61 and having the front end turnably connected to the embankment unit 31, connected with the first link 61 and a connection unit 82 in the middle section, having elastic members 84, 85 facing each other respectively and being fitted in the front side and rear side sandwiching the connection part 82 with the first link 61, and clamping the connection part 82 with the first link 61 and being slidable in an axial direction. By stretching the flexible means 72, the embankment unit 31 is turned vertically.SELECTED DRAWING: Figure 1 |
