FIG. 1 is a rear view of a vibrating ridge coater, FIG. 2 is a plan view of the same, FIG.
FIG. 5 is a plan view of the same, FIG. 5 is a side view of the vertical vibration restricting body 22 disposed inside the support spring 23, and FIG.
FIG.

1 and 2, the entire structure of the vibrating ridge coater will be described.

The tractor mounting link section 26 is mounted on the lower link and top link sections of the tractor, and power is input to the input section 25 from the PTO shaft of the tractor via a joint shaft.
The tractor mounting link portion 26 supports the mud guide frame 8, and a ridge forming portion is formed on a right portion of the mud guide frame 8 in the traveling direction. A belt or a chain is disposed inside the mud guide frame 8, and a mulling rotor 21, a mud lifting rotor 12, a lifting auxiliary disk 11, a lower surface cutting rotor 9, and a top surface cutting rotor 10 driven at a lower portion. Etc. are driving.

The soil at a position away from the ridge A is brought closer to the ridge A by the mulling rotor 21, and the mud dug up by the mud lifting rotor 12 is removed by the lifting auxiliary disk 11 and the mud lifting rotor.
In the state of being held between 12, the mud jumping rotor 12, which rotates clockwise when viewed from behind, jumps up on the ridge A, is received by the mud cover 14, and is rotated by the upper surface cutting rotor 10 and the side surface cutting rotor 9. The old ridges are scraped off and placed on ridge A.

Then, the mud received by the mud cover 14 and dropped on the ridge A is applied in close contact with the old ridge A cut and beaten by the vibrating ridge forming plate 1 located next.

In particular, power is input to the vibrating device V by a flexible shaft 13 that drives the vibrating device V protruding from the rear surface of the mud guide frame 8. Since the vibrating device V vibrates violently up and down and up and down while being suspended and supported by the support spring 23, the power transmission mechanism fixed to the mud guide frame 8 does not allow power transmission with the vibrating device V. The flexible shaft 13 is attached to the left end of the mud guide frame 8 as far as possible from the vibrator V.
And a long flexible shaft 13 is used to input data to the left side of the vibrating device V. The flexible shaft 13
Drives the eccentric rotating body inside the vibro device V,
The vibrator V is vibrated.

On the upper surface of the mud guide frame 8, a vertical adjustment handle 15 of the ridge forming plate 1 is provided within a reach of an operator sitting on a tractor seat, and by rotating the vertical adjustment handle 15, a suspension support cover is provided. 4, the support spring 23, the vibro device V and the ridge forming plate 1
In the state supported by 19, the molding height of the ridge A can be adjusted by vertically moving the ridge A in the direction along the slope of the ridge A.

When detaching the ridge coater from the tractor, two left and right stands 16 and 17 can be attached so that the ridge coater can independently support a predetermined state. Further, a sled body 30 is protruded from below the mud guide frame 8 to the front, and the sled body 30 is configured so that the entire ridge coating machine slides on the soil. On the side of the sled body 30, the biting disk 20 is driven into rotation and bites into the soil, and due to the rotational reaction force of the mud lifting rotor 12 and the soil closing rotor 21,
The entire ridge coater is prevented from being pushed away from ridge A.

As shown in FIG. 6, a mulching plow 32 is arranged at the rear of the ridge coater, and the mulling jumping rotor 12 uses the mulling plow 32 to backfill a groove formed by excavating the mud. ing.

In the above configuration, the present invention provides a vibro device V
Is configured as shown in FIG. 3 to FIG.

That is, by the rotation of the up / down adjustment handle 15, the suspension support cover 4, which is adjusted up and down along the slope of the ridge A by the parallel support links 18 and 19, via the four support springs 23 through the vibrating device V Is supported.

Power is transmitted to the vibrating device V by a flexible shaft 13. The flexible shaft 13 can follow the vibrating device V and vibrate up and down and up and down. When the vibration of the tractor resonates with the vibration of the vibrating device V, the vibrating device V performs unexpected abnormal vibrations up and down, up and down.

A support spring 23 is provided to buffer the vertical vibration of the vibrating device V, and a front and rear support spring 6 is interposed to buffer the front-back vibration.

However, abnormal vibration exceeding the support spring 23 and the front and rear support springs 6 occurs. When the vibrating device V vibrates upward or backward due to the abnormal vibration, the vibrating device V collides with other fixed components such as the suspension support cover 4 and the mud cover 14 to be deformed or damaged.

In the present invention, the following configuration is used to solve this problem.

That is, the upper and lower brackets 24 are projected from the suspension support cover 4,
The vertical vibration restricting body 3 is fixed to the lower end of the upper and lower bracket 24, and the vertical vibration restricting body 3 is configured to contact the upper surface of the vibrating device V.

Further, from the rear end of the suspension support cover 4, a stopper support 5
The vibration control rubber 25 is fixed to the lower end of the stopper support 5 and the front-rear vibration control body 2 protrudes forward from the rear surface of the vibrator device V to abut against the rear face. And
Further, a round regulating frame 26 is fixedly mounted on the vibrating device V around the vibration regulating rubber 25 to regulate front-back, left-right vibration.

In the embodiment shown in FIG. 5, an embodiment in which the vertical vibration restricting body 22 is disposed inside the support spring 23 is disclosed. Also in this configuration, when an abnormal vibration exceeding the supporting force of the support spring 23 occurs, the vertical vibration restricting body 22 abuts between the suspension support cover 4 and the vibrating device V, and the vertical vibration The regulator 22 buffers this.

(F) Effects of the Invention The present invention is configured as described above, and has the following effects.

If only the vibration of the vibrating device V is used, the support spring 23
And vibration exceeding the range of the supporting force of the front and rear support springs 6
Although it does not occur in the calculation, the rolling and pitching of the tractor, the rolling and pitching of the flexible shaft 13, and the vertical swing transmitted by the sled body 30 due to the unevenness of the soil surface are transmitted. When resonating with the vibration of the device V, the vibro device V may generate unexpectedly large abnormal vibration.

In such a case, the present invention is applied to the front-rear vibration regulating body 2.
The vertical displacement restricting body 3 prevents abnormal displacement due to abnormal vibration and prevents important parts such as the support spring 23 and the front and rear support spring 6 from being damaged.
