Reference numeral 12 denotes a cover member. The cover member 12 is provided on the machine frame 3 above the rotary rotor 5 and above the ridge, and a rubber rear cover 13 is provided on the rear side of the cover member 12 in the traveling direction.
Is suspended vertically.

14 is a ridge body, and the ridge body 14 is an upper plate portion 14a and a side plate portion 1.
By 4b, it is formed into a vertical cross section that matches the upper surface of the ridge and one side surface of the ridge.

Reference numeral 15 denotes a vibration mechanism. In this case, two links 16 are pivotally supported on the machine frame 3 by a pull-up spring 17, a take-out body 18 is provided at a tip end of the link 16, and a support frame 20 is provided on the mounting body 18 by a spring 19. And a corner 14 between the upper plate portion 14a and the side plate portion 14b of the ridge body 14.
c The side plate portion 14b side is attached to the support frame 20, and two eccentric plates 21 are rotatably supported in the support frame 20. In this case, the intermediate normal on the upper surface of the ridge 4 and the intermediate normal on the side of the ridge. And an eccentric disk 21 is located on l ₁ , which is P away from the line 1 connecting the intersection of the ridge and the ridge angle point, and a chain mechanism is provided between the power shaft 8 and the input shaft 23 of the speed change mechanism 22. 24, the output shaft 25 of the transmission mechanism 22 and the eccentric 21 are connected by a flexible shaft 26,
The eccentric disks 21 are provided so as to be able to transmit rotation by a belt 27, and the ridge tightening operation is performed by vibration caused by the rotation of the eccentric disks 21.

Reference numeral 28 denotes a vertically movable wheel for supporting the machine frame 3.

In this embodiment, the traveling machine 1 travels along the old ridge 4 and rotates the power take-off shaft 6, while the rotating rotor 5 continuously crushes the field soil into the old ridge while the power take-off shaft 6 is rotated. The cover member 12 and the rear cover 13 prevent the mud from being scattered above the rotary rotor 5 and to the side of the ridge. On the other hand, the upper surface of the ridge 4 and one side surface of the ridge 4 are shaped into a vertical section by the ridge tightening vibration of the vibration mechanism 15. The ridges 14 are tightened in a state where they are sandwiched, and the ridge work is performed. At this time, the vibration mechanism 15 includes an eccentric disk 21 which is rotated by a power take-out shaft 6 of the traveling body 1 via a flexible shaft 26. The structure is such that ridge tightening vibration is imparted to the ridge body 14 by the unbalanced rotation of the eccentric disk 21, and the ridge tightening vibration capability can be varied by changing the rotation speed of the flexible shaft 26 by the transmission mechanism 22. Can, and therefore, on the other hand The ridge tightening vibration capacity can be varied in accordance with different soil conditions, soil conditions due to the weather at the time of work, soil softness, moisture content, and the work efficiency can be improved by itself. Water can be prevented well, and a strong ridge can be obtained.

At this time, the ridge tightening vibration of the vibration mechanism 15 is
Since it is transmitted to the side plate portion 14b side closer to the continuous corner portion 14c between the a and the side plate portion 14b, the ridge tightening on one side of the ridge is good, so that leakage of paddy water can be prevented well, and an excellent ridge can be formed. Obtainable.

 It should be noted that the present invention can be applied to a case where a plurality of ridges 14 are arranged.

〔The invention's effect〕

As described above, the present invention has a structure in which the vibration mechanism includes an eccentric disk that rotates via a flexible shaft by the power take-off shaft of the traveling body, and imparts ridge tightening vibration to the ridge body by unbalanced rotation of the eccentric disk.
