Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a ridge forming plate support mechanism of a ridge coating machine for mechanically forming ridges of paddy fields into ridge forming plates.

(B) Conventional technology Conventionally, in order to enable hitting of a ridge by a ridge forming plate, a ridge forming plate is attached to the tip of a piston, and the ridge forming plate is pushed and pulled by the piston to form a ridge. Is known.

For example, as disclosed in Japanese Utility Model Application Laid-Open No. 60-57906.

(C) Problems to be solved by the invention However, in the conventional technique, a technique for adjusting the ridge forming plate up and down along the slope is additionally provided. When attached, the mechanism was restricted by this mechanism, so it was not possible to additionally provide a technique for adjusting the position of the same ridge forming plate to the left and right.

Therefore, without adjusting the position of the ridge forming plate 1 to the left and right,
In the case of performing only the vertical position adjustment, if the ridge forming plate 1 is too far from the position of the ridge A, the bent portion of the ridge forming plate 1 is located on the slope as shown in FIG. If the coating machine was too close to the ridge A, there was a problem that the bent portion of the ridge forming plate 1 was located on the upper surface of the ridge A.

 The present invention has solved this problem.

(D) Means for Solving the Problems The problems to be solved by the present invention are as described above. Next, means for solving the problems will be described.

Ridge forming plate 1 to apply mud along cutting ridge A of old ridge
Is supported by a parallelogram link mechanism obliquely arranged in rear view, the upper parallel support links 18 and 19
And the left and right parallel support links 2 and 5 are also rotatable left and right. The parallel support link 2 is pivotally supported at one point by a pivot shaft 35 to form a ridge on the parallel support link 5. The plate 1 is supported.

(E) Embodiment The problems to be solved and means to be solved by the present invention are as described above. Next, the configuration of the embodiment shown in the attached drawings will be described.

FIG. 1 is a perspective view of the ridge coater of the present invention attached to a tractor, FIG. 2 is a rear view of the ridge coater of the present invention, and FIG. 3 and FIG. FIG. 5 is a rear cross-sectional view showing a bad state that does not fit perfectly, FIG. 5 is a side view showing a state in which an upper surface guide wheel 41 and a slope guide wheel 42 are attached to the front of the ridge forming plate 1, and FIG. FIG. 7 is a plan view showing the configuration of the slope retaining plate 3, and FIG. 8 is a rear view of the same.

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.

And the tractor mounting link 26 is the mud guide frame 8
And a ridge forming portion is formed at a right portion of the mud guide frame 8 in the traveling direction. A belt or a chain is arranged inside the mud guide frame 8, and drives a mud lifting rotor 12 and a lifting auxiliary disk 11 that are driven at a lower portion,
A side surface cutting rotor 9, an upper surface cutting rotor 10, and the like are driven by a chain case provided at a front portion of the mud guide frame 8.

The mud excavated by the mud raising rotor 12 is held between the auxiliary lifting disk 11 and the mud raising rotor 12, and the ridge A is rotated by the mud raising rotor 12 clockwise viewed from behind. It is flipped up, received by the mud cover 14, and placed on the ridge A after the old ridge is cut off by the upper surface cutting rotor 10 or the side surface cutting rotor 9.

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 four support springs 23, the power transmission mechanism fixed to the mud guide frame 8 causes power to be transmitted between the vibrating device V and the vibrating device V. Since the transmission becomes impossible, a take-out portion of the flexible shaft 13 is provided at the left end of the mud guide frame 8 as far as possible from the vibrator V, and the input is made to the left side of the vibrator V by the long flexible shaft 13. . The flexible shaft 13 drives the eccentric rotating body inside the vibrating device V, and vibrates the vibrating device V.

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
-While supported by 19, the ridge A is vertically translated in the direction along the slope of the ridge A, so that the molding height of the ridge A can be adjusted.

However, since a supporting portion by an interposed spring is formed between the adjusting portion of the ridge forming plate 1 by the vertical adjusting handle 15 and the ridge forming plate 1, the approximate height of the ridge forming plate 1 is adjusted by the vertical adjusting handle 15. However, the ridge forming plate 1 itself can swing up and down to some extent.

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.

In the above configuration, the present invention is particularly applicable to the ridge forming plate 1.
Is supported by the inclined parallelogram link mechanism, and the upper and lower parallel support links 18 and 19 are also
The left and right parallel support links 2 and 5 can also rotate.

That is, as shown in FIG.
5 and the upper and lower parallel support links 18 and 19 constitute an inclined parallelogram link mechanism, and the upper end of the left and right parallel support link 2 is pivotally supported on the mud guide frame 8 by the pivot shaft 35. The suspension support cover 4 is supported above the parallel support links 5, and the ridge forming plate 1 is suspended from the suspension support cover 4 via the support springs 23 and the front and rear support springs 6.

Left and right parallel support links 2.5 and up and down parallel support links 18
19, four pivot pins 43, 44, 45, 46 are fitted, and the inclined parallelogram link mechanism is such that only the pivot shaft 35 is fixed, and Can also expand and contract.

However, if the degree of freedom to expand and contract back and forth is too large,
Since a problem that the position of the ridge forming plate 1 is not fixed occurs, the spring locking pin 34 at the lower end of the left and right parallel support link 2 is used.
The rotation restricting springs 34 and 36 are interposed between the mud guide frame 8 so that the inclined parallelogram link mechanism does not move more vertically and horizontally than necessary.

In order to prevent the ridge forming plate 1 from moving too freely due to the inclined parallelogram link mechanism and the ridge forming plate 1 not being along the ridge A, a problem shown in FIGS. 5 and 6 is prevented. As described above, the upper surface guide wheel 41 and the slope guide wheel 42 protrude from the portion of the suspension support cover 4 to the front position of the ridge forming plate 1, and are configured to follow the ridge A by the guide wheels.

Also, as shown in FIG. 2, the mud is disposed in front of the ridge forming plate 1, and is located inside the mud cover 14 at a position where the mud jumped up from the mud lifting rotor 12 falls. However, in order to solve the problem that it flows down without stopping on the slope, the slope retaining plate 3
Has been arranged. The slope retaining plate 3 includes a mounting bracket 40.
Except for the part, the part is made of an elastic body such as rubber, so that even if the part collides with the slope, the slope retaining plate 3 is deformed and immediately returns to the original shape. .

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

In the conventional ridge coater, the upper and lower positions of the ridge forming plate 1 can be adjusted, but at the same time, the left and right positions of the ridge forming plate 1 cannot be adjusted.

Therefore, when an inexperienced operator operates the tractor, when the position of the tractor moves away from or near the ridge A, the ridge forming plate 1 does not follow the ridge A, moves away or approaches, and the adhesion of the mud on the ridge A decreases. There was a problem of doing it.

In the present invention, an inclined parallelogram link mechanism is constituted, and the inclined parallelogram link mechanism is one part at the pivot shaft 35.
Since it is supported on the mud guide frame 8 by points, it is possible to move both up, down, left and right by expansion and contraction of the inclined parallelogram link mechanism, and even if the tractor slightly approaches or separates from the ridge A, The ridge forming plate 1 can always be made to follow the ridge A.

As a result, it was possible to improve the adhesion state of the mud to the ridge A.
