DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a mud lifting mechanism of a ridge coating machine in which mud in a paddy field is lifted up by a mud lifting rotor and formed by a ridge forming plate.

(B) Conventional technology Conventionally, a technology in which a mud lifting rotor is provided as a mud lifting mechanism of a ridge coating machine is known.

For example, as disclosed in Japanese Patent Application Laid-Open No. 58-51802.

(C) Problems to be solved by the invention However, the mud lifting rotor alone cannot lift mud when the soil has a lot of moisture.

In such a case, a mud lifting rotor is disposed in parallel with the mud lifting rotor, and the mud is transported by holding the lift discs together.

In the case where the mud lifting rotor and the lifting auxiliary disk are provided side by side in this way, in order to further increase the holding power of the mud, the surface of the lifting auxiliary disk on the mud lifting rotor side is jumped. The raising blade protrudes.

By making the retreat angle of the lifting blade 6 changeable, it is possible to cope with hard and soft mud.

(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.

The mud lifting mechanism of the ridge coater is configured so that the lifting auxiliary disk 11 and the mud lifting rotor 12 are rotated on the same axis, and the surface of the lifting auxiliary disk 11 on the mud lifting rotor 12 side is jumped. The lifting blade 6 is fixed, and the retraction angle of the lifting blade 6 can be changed.

(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.

1 is a rear view of the ridge coater of the present invention, FIG. 2 is a plan view of the same, FIG. 3 is a plan view showing a partition plate inside the mud cover 14, and FIG. Perspective view, fifth
FIG. 6 is a side view showing the mounting of the lifting blade 6 to the lifting assist disk 11, and FIG.

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

In the ridge coater, the tractor mounting part to the work equipment mounting device is composed of the top link mounting part 32 and the lower link mounting parts 33, 33, and power is input to the input shaft 50 from the tractor's PTO shaft via the joint shaft. .

The lower link mounting section 33 and the top link mounting section 32
Is attached to the front surface of the mud guide frame 8 constituting the main body of the ridge coater.

A ridge forming portion is formed at the 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 at a lower portion.

The present invention relates to a configuration of a lifting auxiliary disk 11 and a mud lifting rotor 12, and a lifting blade 6 is attached to a surface of the lifting auxiliary disk 11 on the mud lifting rotor 12 side. The retraction angle of the lifting blade 6 can be changed.

Further, the chain case 27 and the rotor cover 36 provided at the front part of the mud guide frame 8 are pivotally supported by a pivot shaft 38, and the slope cutting rotor 9, the upper surface cutting rotor 10 and the like provided inside the rotor cover 36 are provided. Power is being transmitted.

The slope and upper surface of the old ridge are cut by the rotation of the slope cutting rotor 9 and the upper surface cutting rotor 10 so that mud is easily attached.

The mud dug up by the mud lifting rotor 12 is held between the lifting auxiliary disc 11 and the mud lifting rotor 12, and is supported by the mud lifting rotor 12 which rotates clockwise when viewed from behind. In the direction of the plate 11 and the mud lifting rotor 12,
It is flipped up on the ridge A, received by the mud cover 14, and placed on the ridge A after the old ridge has been cut off by the upper surface cutting rotor 10 or the side surface cutting rotor 9.

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

Vibro device V protruding from the rear surface of mud guide frame 8
Power is input to the vibrator V by the flexible shaft 13 that drives the motor. The vibrating device V swings violently up and down and up and down while being suspended and supported from the suspension support cover 4 by four support springs 23 and one front and rear support spring.

Therefore, the power transmission mechanism fixed to the mud guide frame 8 makes it impossible to transmit power to and from the vibrator V, so the flexible shaft 13 is attached to the left end of the mud guide frame 8 as far away from the vibrator V as possible. 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 an eccentric rotating body inside the vibrator V, and the vibrator V
Vibrates.

The ridge forming plate 1 is supported below the suspension support cover 4, and the suspension support cover 4 is supported by the mud cover 14 by the parallel support links 5.

The suspension support cover 4, the support spring 23, the vibrating device V, and the ridge forming plate 1 are composed of parallel support links 18 and 19 and inclined links 15.
Supported by In the state supported by these, the forming height of the ridge A can be adjusted also by moving up and down in parallel in the direction along the slope of the ridge A.

The mud cover 14, the parallel support link 5, and the suspension support cover 4
Is adjusted up and down by the up and down adjustment handle 25,
Since a support portion by a support spring 23 is formed between the suspension support cover 4 and the ridge forming plate 1, the vertical adjustment handle 25
The height of the ridge-shaped plate 1 itself can be adjusted to some extent up and down.

When the ridge coater is detached from the tractor, two stands 16 and 17 on the left and right sides can be mounted so that the ridge coater can independently support the predetermined condition.

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
The entire ridge coater is prevented from being pushed away from ridge A by the rotational reaction force of 12 and the mulching rotor 21.

FIG. 3 discloses the arrangement of the partition plates 26 and 27 disposed inside the mud cover 14.

When the soil that is lifted from the mud lifting rotor 12 is clay, it is necessary to widely open the opening 14d from the mud cover 14 to the rear, so that the mud moves rearward along the clay partition plate 25. Make up. In the case of ordinary soil, the opening 14d does not have to be large, so that it is configured to reach the opening 14d along the partition plate 26. 14a
Is the side plate of the mud cover room, 14b is the front plate of the mud cover room, 14c
Is also a rear plate.

Thus, by exchanging the partition plates 25 and 26, the direction of the soil falling from the mud cover 14 onto the cutting ridge can be controlled.

FIG. 4 discloses the configuration of a mud lifting cover 22 that covers the rotating outer circumference of the mud lifting rotor 12 and the lifting assist disc 11.

A turning plate 3 for preventing the mud excavated by the mud lifting rotor 12 from being pushed to the front is attached to the front surface of the mud lifting cover 22.

The role of the spinning plate 3 is that the tractor sinks and the position of the mud jumping rotor 12 of the ridge coater becomes deeper because the field is soft in clayey soil. Since mud is accumulated and the rotational resistance of the mud jumping rotor 12 may be increased, this is solved.

That is, by providing the turning plate 3 at the front part of the rotation locus of the mud lifting rotor 12, excess soil does not enter from this portion, and the rotational resistance of the mud lifting rotor 12 is less likely to increase. .

The lifting blade 6 is attached to the surface of the lifting auxiliary disk 11 on the mud lifting rotor 12 side. In the present invention, the retreat angle of the lifting blade 6 can be changed.

FIG. 5 discloses the shape of the jumping blade 6 which can change the sweep angle.

In the ridge coater, changes in the moisture and soil quality of the mud change the way the mud flies, resulting in different ridge hardness and the inability to form a new ridge.

As for the tendency of the soil, dry sandy materials fly well, and clay-rich ones are difficult to fly.

According to the present invention, in order to adjust the flying condition of the mud which is different in sandy and clay-like materials, the lifting blade 6 attached to the lifting assist disk 11 can be changed in retreating angle. The bolt retraction angle of the lifting blade 6 can be adjusted by setting the bolt fixing hole 6 as an elongated hole 6a and adjusting the portion of the elongated hole 6a when fastening the bolt.

As another configuration, as shown in FIG. 5, the lifting blade 6 is configured to be fixed with bolts,
It is also possible to provide two types of fixing bolt holes, 40 and 41, so that they can be changed to sandy or clay.

In FIG. 6, a part of the lifting assisting disk 11 is made removable.

That is, the detachable plate 2 is provided on the lift-up auxiliary disk 11 and the detachable plate 2 is bolted to the auxiliary lift-up disk 11
It is made removable.

The shape of the removable plate 2 is a fan-like shape obtained by cutting the outer periphery of the flip-up assisting disk 11, so that only one can be removed.

By removing the detachable plate 2, it cannot be lifted by the mud lifting rotor 12, cannot escape backward, stays in front of the lifting auxiliary disk 11,
The mud, which has become the running resistance, can escape backward from the opening of the lift-up auxiliary disc 11.

In the case of low-moisture soil, the detachable plate 2 is mounted to prevent the muddy soil from escaping backward by the lift-up auxiliary disk 11, and the entire amount of muddy is thrown toward the muddy cover 14. .

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

First, when the paddy soil is sandy and clayy, the jumping direction and the distance are different. Sandy materials with low moisture content fly well, while clay materials with high moisture content do not fly easily. However, the position of the jumping blade 6 is changed in accordance with these cases, and the mud is constantly jumped to the optimum position of the mud cover 14.

Second, the amount of jumping can be changed by comparing the shape of the mud jumping rotor 12, but the replacement of the mud jumping rotor 12 is costly.

In the present invention, since only the position of the lifting blade 6 attached to the lifting assisting disk 11 is changed, the distance at which mud is lifted can be changed at low cost.
