Description of the Related Art When repairing an old ridge and forming a new ridge, the upper part of the old ridge that has been destroyed by weathering etc. is scraped off and earth is filled there, and the embankment is compacted by a ridge arranging machine. As a ridge forming machine having a pretreatment mechanism for forming a ridge, one disclosed in JP-A-60-98903 is proposed.

いた。As shown in FIG. 10, this ridge forming machine is provided with a rotary rotor c which is built up on an old ridge b on a machine frame a connected to a tractor, and which is provided at a front position in the traveling direction of the rotary rotor. A rotary cutting blade d for scraping off the upper part of the ridge is provided. The rotation direction g of the rotary rotor b is set so as to cut into the ridge e of the old ridge and the inner portion f of the old ridge from the rice field side toward the old ridge side. It is considered that the reason why the rotation direction was set in this manner was to enable the soil to be scraped directly onto the excavated old ridge in a short distance. Further, the rotary cutting blade is configured to be adjustable up and down by an adjusting device h so that the cutting depth can be appropriately selected by adjusting the relative position between the upper surface of the ridge and the cutting blade.

【発明が解決しようとする課題】しかしながら前記構成

き上げに大きな負荷がかかることとなり、駆動装置を大
馬力のものに構成する必要があった。However, the ridge forming machine having the above-mentioned structure has the following problems. Since the rotation direction of the rotating rotor was set so that it cuts from the rice field side toward the old ridge side, the rotating rotor should scrape the soil upward from the hem of the old ridge that is tightly tightened. Becomes Therefore, a large load is applied to the soil scraping by the rotary rotor, and it is necessary to configure the drive device to have a large horsepower.
【0005】 又、回転ロータの回転方向がこのよう

るために、土が大きい固まり状態で掻き上げられ易い。
このようなことから、整畦時に盛土を締め固めにくく、
木目の荒い強度的に不安定な畦が形成され易い問題があ
った。Further, since the rotation direction of the rotary rotor is set in this way, the soil on the ridge side, which is often in a dry and hard state, is mainly supplied onto the old ridge. Moreover, since the soil of the old ridge is scraped upward from the hem, the soil is easily scraped in a large solid state.
Because of this, it is difficult to compact the embankment when arranging,
There was a problem that rough ridges with rough grain and unstable strength were easily formed.
【0006】 前記畦形成機は、回転削出刃を上下動

に不足を来し易く、均一に締め固められた強度のある畦
を形成し難い問題があった。In the ridge forming machine, the rotary cutting blade is configured to be vertically movable. Therefore, when the upper surface of the old ridge is low, the rotary cutting blade may be lowered to scrape off the upper portion of the old ridge. It has the advantage that it can. However, when cutting is performed by lowering the rotary cutting blade in this way, it is necessary to increase the amount of earth fill to that portion by the amount corresponding to the reduction. However, in the conventional ridge forming machine, even if the rotary cutting blade is lowered, the rotary rotor is not automatically lowered to increase the amount of soil scraped. Therefore, there is a problem in that the amount of embankment tends to be insufficient and it is difficult to form uniformly compacted and strong ridges.

なる不都合も生ずる。In this case, it is possible to lower the depth of the rotary rotor to deepen the cutting depth of the rotary rotor. However, in this case, the rotary cutting blade is also lowered more than necessary at the same time, so that the rotary cutting blade is It is necessary to readjust the vertical position,
The workability of arranging will be significantly deteriorated. Further, since the rotating rotor is lowered, the ridge portion is abnormally deeply shaved off, which causes a disadvantage that the backfilling of the portion needs to be repaired.

Since it was set to cut from the side of the rice field toward the inner part of the old ridge, when it was rotated, the soil scraped up would scatter to the adjacent rice field, and the soil scraped up would be cleaned. Therefore, it cannot be used effectively. Therefore, it is necessary to specially dispose the soil receiving plate k as shown in FIG. 9 for preventing the scattering of soil.

る。Further, since the rotating direction of the rotating rotor is set in this way, when the tire of the tractor travels in a portion close to the old ridge hem, the rotating rotor is
It will scrape up the soil on the rice field that is stepped on by the tires. Particularly in the case of arranging wetlands, as shown by the alternate long and short dash line in FIG. 10, the running portion of the tire is often deeply depressed by 20 cm to 30 cm. In this case, no matter how the rotating rotor c is lowered, it becomes difficult for the blade edge to contact the bottom surface n of the recessed portion, and it is practically impossible to scrape the soil by the rotating rotor, and it is impossible to arrange the soil. Invited. As described above, when the conventional ridge forming machine is used, it is possible to deal with the adjustment of dry fields, but it is not necessary for the adjustment of wet fields (the dry fields easily become wet due to rainfall after plowing). I couldn't handle it.

FIG. 5 shows that the movable holding member 11 is set in a required rotating state according to the height of the upper surface of the old ridge, and is fixed in that state, and the rotary cutting blade 43 and the earth embossing rotor 49 rotate counterclockwise. It shows how they are doing. In this figure, the tire of the tractor (traveling machine) travels in a portion close to the old ridge hem, and a recess 72 is formed at the ridge. By the rotation of the rotary cutting blade 43, the entire upper part 40 of the old ridge and the upper part 41 of the inner part of the old ridge are scraped off in series. By the rotation of the earth embankment rotor 49, the soil of the old ridge is scraped off from the inner side of the old ridge toward the ridge while being finely crushed by the left rotation portion 49a (reference numeral 7).

なる。FIG. 6 shows a case where the wetland condition is stronger and a deeper dent 72 is formed on the ridge due to the running of the tire of the tractor (traveling machine). In the case shown in FIG.
Since the depression is relatively shallow, the earth of the bottom portion 72a of the depression can be scraped up by the rotation of the earth embossing rotor. However, when such a deep depression is formed, the earth embossing rotor 49 is used in the depression. You will not be able to scrape the soil. Therefore, the movable holding member 11 is rotated counterclockwise from the state shown in FIG. 5 by a required angle so that the soil 72 can be scraped up more efficiently by avoiding the depression 72 as much as possible, and the movable holding member is held in that state. The member 11 is fixed in position. In order to clarify the difference between the locus of the earth-filling rotor when the movable holding member 11 is rotated in this manner and the locus of the earth-filling rotor 49 shown in FIG. 5, in FIG. 6, in the case of FIG. The locus is shown by a dashed line. As a result, the amount of cutting by the rotary cutting blade 43 increases, but the right-side rotating portion 49 of the earth-filling rotor rotated counterclockwise.
Since the amount of scraping by b can be increased (the amount of soil in the part surrounded by the solid line and the alternate long and short dash increases), the required amount of scraping can be secured. Incidentally, in this case, if the movable holding member 11 is not rotated, the state shown in FIG. 7 is produced, and the right side rotating portion 49b of the earth-filling rotor is cut off, and the required amount of scraping cannot be secured.

給できることとなるからである。The present invention has the following excellent effects. According to the present invention, since the movable holding member is pivotally attached to the fixed holding member so as to be rotatable about the axis of the drive shaft, the following items can be obtained not only in the dry field but also in the wet field. For the reason, the advantage that can be surely and easily performed is remarkable. That is,
When the tire of the traveling machine runs near the hem of the old ridge, in a wetland, 20c is applied to the running part of the tire.
Although a depression with a depth of m to 30 cm is often generated, the movable holding member is rotated by a required angle to separate the earth-filling rotor from the ridge hem, thereby avoiding the depressed rice field portion as much as possible. This is because it becomes possible to scrape up the soil on the side of the other side, and therefore, the amount of soil required for arranging can be supplied onto the old ridge.

Even when scraping up the soil while scraping the inner part of the old ridge, it is easy to cut from the inner part with relatively low hardness.
Therefore, the scraping can be performed in a state where the load is not so high. Therefore, it is not necessary to configure the drive device to have a large horsepower as in the conventional ridge forming machine described above.

を解決できる大きな利点を有している。Further, in the present invention, since the rotation direction of the earth-filling rotor is set so as to cut into the rice field in the direction away from the hem of the old ridge, the soil on the soft rice field, which is moist and soft, is mainly used. , Can be supplied to old ridges in a finely crushed state. Therefore, it is possible to form a ridge with good tightening strength and stability by compaction by the ridge adjuster. When using a conventional ridge forming machine that rotates the rotating rotor in the opposite direction, as described above, in order to scrape the old ridge soil upward from the hem, the dry and hard old ridge soil is scraped up. Is easily scraped up in a large clumped state, it is difficult to compact the embankment during leveling, and there is a problem that rough ridges with rough grain and strength are easily formed, but the present invention has a great advantage of being able to solve this. have.
