As shown by, the base end portion 51 is engaged with a required one of the engaging recesses 55 to fix the height of the rotary ridge member 43.

After the rotating ridge member 43 is set in the ridge state as described above, when the walk-behind towing vehicle 2 is advanced, the rotation of the rotary ridge member 43 is accelerated by the rotation speed increasing device 42. However, the speed is increased more than the rotation of the axles 9 and 10.
At the same time, the drive shaft 20 is forcibly rotated via the chain 29, and the rotation of the rotating shaft 32 causes the scraping and scraping rotor 33 to be forcibly rotated at a high speed. As shown in FIG. 7, the scraping and scraping rotor 33 simultaneously scrapes the inner part 39 of the old ridge and the rice field part 40 at the ridge of the old ridge and scoops and scrapes the shaved soil as shown in FIG. The guide cover 3
5 and embankment is carried out on the ridge forming portion (cutout concave portion) 41 formed by the shaving as shown by a dashed line in FIG.

The embankment 6, that is, the soil laid between the ridge inner side surface forming body 60 and the ridge outer side surface forming body 62 is compacted into the ridge 3 by the rotation of the rotary ridge forming tool 43. However, as described above, since the rotation of the rotary ridge member 43 is accelerated more than the rotation of the axles 9 and 10 by the rotation speed increasing device 42, the ridge upper surface forming body 57 and the ridge inner surface forming body 60 are rotated.
The ridge outer surface forming body 62 slips and rotates with respect to the embankment 6 to compact the ridge surface. As a result, a strong ridge with less surface irregularities is formed.

If the rotary ridge member 43 does not accelerate, the ridge upper surface forming member 57, the ridge inner side surface forming member 60, and the ridge outer surface forming member 62 only roll with respect to the embankment. The furrowing device 43 ends up merely stroking the outer surface of the embankment at the furrow forming part, and the furrow becomes easily broken.

The ridges are arranged as shown in FIGS.
Since the protruding portion 71 in the form of a saw blade becomes a cutting blade and cuts into the rice field portion 40 at the ridge, the outer surface 103 (the outer surface of the conical plate portion) 103 is formed at the lower end of the inner surface 59 of the ridge. Is compacted by slip rotation. Therefore, a ridge excellent in stability can be formed. Since this cutting is performed by using the saw blade-shaped projection 71 as a cutting blade, the cutting into the rice field is performed easily and reliably. Therefore, it is possible to effectively prevent the outer peripheral edge side portion of the ridge inner side surface forming body 60 from smoothly cutting into the rice field surface, and to prevent the rotating ridge member from tending to jump, and does not hinder the straight running of the walking type towing vehicle as much as possible. The ridge work can be stably performed in the state.

Also, as described above, since the traction force of the left wheel 11 far from the ridge is set to be greater than the traction force of the right wheel 12 when the ridge is being arranged, the inner surface of the ridge having a conical outer surface is formed. When the body 60 rotates while pressing the embankment 6 in the ridge forming section, the walking type towing vehicle 2 is driven by the ridge 3
Can be effectively prevented from moving away from the ground, whereby the conical outer surface 67 can act to firmly compact the embankment side surface while securing the straightness of the walk-behind towing vehicle. It will be possible to form a stable and stable ridge.

In this embodiment, the ridge inner surface forming member 60 and the ridge outer surface forming member 62 are formed as umbrella-shaped rotating members having ridge line corners 69 and 85 arranged on the outer surface thereof in a circumferential direction. As a result, when the ridge inner surface forming body 60 and the ridge outer surface forming body 62 rotate, the ridge line corners 69 and 85 can sequentially press the ridge side surfaces, whereby the ridges can be compacted. It will do better.

Since the rotary ridge member 43 is arranged on the side of the part where the worker walks, the rotary ridge member 43 and the formed ridge become obstacles for the walking operation of the walking type towing vehicle. Therefore, the stable furrowing can be easily performed.

After the predetermined ridge is completed, the handle 50 is pushed inward to release the engagement between the base end portion 51 and the engagement recess 55, and then the guide hole 53 is inserted into the guide hole 53. Move the handle 50 upward, and rotate the
12, the handle 3 is raised to a height that does not hit the formed ridge 3, and the proximal end portion 51 of the handle is engaged with the upper engaging recess 55 as shown by a dashed line in FIG. In the mating state, the position of the rotary ridge member 43 is fixed, and the rotary ridge member 43 is removed from the ridge 3 by the traveling of the walking towing vehicle thereafter.

FIG. 13 shows the base portion 5 of the rotating arm 44.
1 shows a state in which the height of the rotary ridge member 43 at the time of ridge setting is set by engaging with the engaging recess 55 at the upper position. It almost coincides with 104. In the case where the position of the rotary ridge arrangement tool 43 is set to be high as described above and the ridge is adjusted, the ridge 3 having a height higher than that described above can be formed.

FIG. 14 shows a case in which a rotary ridge member 43 in which the diameter of the ridge inner side surface forming body 60 is larger than that described above is mounted on the support shaft 47.

(6) The embankment device 5 that continuously supplies the soil to the ridge forming section in a swelled state is a combination of a rotary cutting blade for shaving the old ridge as required and an embankment rotor for scraping at least the soil on the rice field. It may be configured. Alternatively, if the shaving of the old ridge has already been completed, the ridge may be constituted only by the embankment rotor that continuously supplies the soil to the ridge forming portion in a raised state.

(7) In order to prevent the walking type towing vehicle from moving away from the ridge due to the reaction force when the ridge inner side surface forming body 60 rotates while pressing the embankment of the ridge formation portion, As another means for increasing the traction force of the wheel far from the vehicle, the traveling of the walk-behind traction vehicle may have a component force toward the ridge so as to be able to resist the reaction force. For example, as shown in FIG. 18, a regulating wheel 113 inclined as required toward the ridge 3 is attached to the walking type towing vehicle, and the regulating wheel 1
It is also possible to configure so that the traveling of the walk-behind towing vehicle has a component force toward the ridge by the direction regulating action of 13.

Further, it is also possible to adopt a method of increasing the traction force of the wheel far from the ridge by moving the wheel far from the ridge farther from the mission device than the wheel near the ridge.

(9) As shown in FIG. 19, the rotating ridge member 43 constituting the ridge forming device is formed by
An axis of rotation 116 eccentric to the axis 115 of the cone
Sometimes rotated around. In the case of such a configuration, the ridge inner surface forming body 60 is eccentrically rotated with respect to the embankment with a slip phenomenon, so that the ridge surface can be more compacted. In this case, the ridge upper surface forming body 57 and the ridge outer surface forming body 62 may also be configured to perform eccentric movement in the vertical direction. FIG. 20 shows a state in which the axis of the cone of the ridge inner surface forming body 60 and the axis of the support shaft 47 intersect, and the ridge inner surface forming body 60 is attached to the support shaft 47. In such a configuration, the eccentric rotation of the ridge inner surface forming body provides a tapping action on the inner surface of the ridge, and the compaction of the ridge becomes more stable.

(10) In the present invention, the rotary ridge member 43 constituting the ridge forming device comprises a ridge upper surface forming member for forming the upper surface of the ridge and a ridge inner surface forming member for forming the inner surface of the ridge. If the ridge upper surface forming body and the ridge inner side surface forming body are capable of compacting the ridge surface by slip rotation with respect to the embankment of the ridge forming portion, the ridge upper surface forming body and the ridge inner side surface forming body In addition to being formed as a perfect circular surface or a perfect conical surface, it is possible to employ various modes in which the surface has irregularities and forms a circular surface or a conical surface in a rotating state. or,

[0061]

The present invention has the following excellent effects. (1) When using the walking type ridge forming machine according to the present invention, since the vertical height of the rotating ridge forming device constituting the ridge forming device can be adjusted through the height adjusting means, the same rotating ridge forming device is used. In the case where ridges are formed using a ridge, by adjusting the height of the rotating ridges, both low and high ridges can be easily formed in a certain height range. .
If necessary, the ridge can be replaced with a rotary ridge having a larger diameter to form a higher ridge.

(2) When setting the rotating ridges to the old ridges, it is necessary to temporarily raise the rotating ridges above the old ridges as shown in FIG. On the other hand, in order to remove the rotating ridges from the ridges after completing the ridges, it is necessary to raise the rotating ridges to a height that does not hit the ridges formed by them. According to the invention,
By moving the rotary ridger in the vertical direction by the height adjusting means, such an operation can be performed easily and reliably without damaging the ridge.

(3) According to the present invention, the height adjusting means comprises a rotating arm extending in the forward direction of the walking type towing vehicle, and the front end portion of the rotating arm is connected to the walking arm. In order to adopt a configuration in which the turning arm is pivotally attached to the front end side of the mold towing vehicle so that the turning arm can turn in the vertical direction, and the turning arm is provided with the turning ridge, the turning arm has The height of the rotary ridges can be easily and reliably adjusted by the rotation operation.

(4) Further, in the present invention, the height adjusting means is constituted by a rotating arm, and the height adjusting means is provided at a front end side of the walking type towing vehicle in a direction perpendicular to a forward direction of the walking type towing vehicle. A drive shaft is provided, and a front end side portion of the rotating arm is pivotally attached to a pivot shaft concentric with the axis of the drive shaft so that the rotating arm can rotate vertically. At a substantially central portion of the arm in the front-rear direction, a support shaft is provided to protrude laterally, and a rotary ridge is provided on the support shaft, and the rotary ridge is connected to the drive shaft via a transmission element, Through the transmission element by the rotation of the drive shaft, because it is configured to forcibly rotate the rotary ridges,
The advantage of being able to easily and surely adjust the height of the rotating ridge member by rotating the rotating arm is that the chain is not loosened regardless of the rotating state of the rotating arm. There is.

(5) In particular, when the walk-behind tractor is a tailor, the rotating ridges adjusted by the height adjusting means are present at substantially the center of the tailor in the front-rear direction (located substantially on the lateral side of the wheel). When the setting is made as described above, the self-weight of the walk-behind towing vehicle can be effectively used to form the ridge stably while minimizing the vertical vibration of the rotary ridge tool.

(6) Since the walking type ridge forming machine according to the present invention is constructed by using a walking type towing vehicle instead of the conventional tractor, the ridge forming machine has a short front-to-rear length. It can be made small. Therefore, it can be easily moved and introduced to the terraced terraces in the mountainous area. Also, since the front-rear length of the walking-type ridge forming machine is short, as shown in FIG. The old ridge portion 119 having a length L7 where the ridge cannot be painted can be shortened. Therefore, unlike the conventional large ridge forming machine using a tractor in which the length of the old ridge portion where the ridge is not covered is long, the manual ridge forming work can be reduced, and labor saving of ridge formation can be achieved. In addition, since the front and rear lengths of the ridge forming machine are small and small turning is possible, even a winding ridge such as a ridge of a rice field in a mountainous area where arable land is not arranged can be easily formed.

(7) With respect to the wheel far from the ridge, the traction force is increased, or the traveling of the walking type towing vehicle can resist the reaction force when the ridge inner side surface forming body rotates while pressing the embankment. By configuring so as to have a component force toward the ridge, the walking type towing vehicle separates from the ridge due to the reaction force when the inner surface forming member of the ridge rotates while pressing the embankment of the ridge forming portion. This can be effectively prevented, whereby the levee can be stably laid while ensuring the straightness of the walk-behind towing vehicle.

(8) In the present invention, when a portion on the outer peripheral edge side of the ridge inner surface forming body is configured as a cutting portion in which protruding portions having tapered front sides are arranged side by side in the circumferential direction, Since the protruding portion such as a saw blade becomes a cutting blade and cuts into the rice field at the ridge, the outer surface of the protruding portion compacts the embankment side by slip rotation. Therefore, the inner side surface of the ridge can be firmly compacted including the lower end portion, and a ridge having excellent stability can be formed. And since this biting is performed by using the saw blade-shaped projection as a cutting blade, the outer peripheral portion of the ridge inner surface forming body can be easily and reliably cut into the rice field. Therefore, it is possible to effectively prevent the rotating ridges from tending to jump without the outer peripheral portion of the inner surface of the ridge being smoothly cut into the rice field surface, and to stably prevent the walking-type towing vehicle from traveling straight as much as possible. It will be possible to perform the ridge work.

(9) The embankment device is configured to include a scraping and scraping rotor that rotates around an axis that is substantially perpendicular to the length direction of the ridge, and the scraping and scraping rotor is rotated by rotating the shaving rotor from the old ridge to the rice field. Along with cutting off the old ridge and the rice field, scooping and scraping the shaved soil and embankment on the shaved old ridge, the shaving of the old ridge and embankment can be performed simultaneously, The embankment device can be made compact.
