【００１５】
この実施の第一形態例は上記構成であるから、作業者はハンドル３を把持し、走行機体１のエンジン２の駆動により車輪４及び回転整畦体６を回転させ、ハンドル３を操作しつつ走行機体１を旧畦に沿って走行すると、進行方向前方にして斜め下向きの回転軸１３に設けた削土ロータ５は畦際を削土し旧畦上に連続的に跳ね上げると共に回転整畦体６は回転し、削土された土を回転整畦体６の強制的なスリップ回転により回転圧接して整畦することになり、しかして、走行機体１の進行方向後部にハンドル３を突設し、走行機体１の一方側部に車輪４を配設すると共に走行機体１の他方側部に削土ロータ５及び車輪を兼ねる回転整畦体６を配設して構成しているので、駆動系統の簡素化も相俟って、機械の小型軽量化を図ることができ、機械の運搬が容易となって、山間部の圃場の整畦作業に適するものとなり、使用の融通性を高めることができる。

【００１７】
又、この場合、回転整畦体は畦Ｗの一方側面Ｗ₂を回転整畦可能な側面整畦部６ａ及び畦Ｗの上面Ｗ₁を回転整畦可能な上面整畦部６ｂとからなるので、畦Ｗの一方側面Ｗ₂及び畦Ｗの上面Ｗ₁を同時に回転整畦することができ、良好に締圧することができ、又、この場合、上記圧締面部Ｋ・Ｄの間に通穴Ｆ・Ｃを形成すると共に圧締板体Ｇ・Ｅを可撓性板材により形成しているので、通穴Ｆ・Ｃにより一層断続的に畦面を締圧することになり、それだけ強固に締圧することができると共に可撓性により圧締板体Ｇ・Ｅは撓み動作しつつ盛土を徐々に締圧することができ、回転整畦体６の外周部分への土の付着現象を抑制することができ、畦の上面Ｗ₁と一方側面Ｗ₂との畦角部を良好に締圧することができ、良好な整畦作業を行うことができ、一層堅牢な畦を得ることができる。
【００１８】
又、この場合、走行機体１に圃場面Ｍ内に穿入可能な抵抗部材２４を配設しているので、上記回転整畦体６の強制的なスリップ回転と上記車輪４の実質的にスリップ回転のない進行回転とにより生ずる走行機体１の過大な牽引走行に対して抵抗し、過大な牽引走行を抑制することができ、それだけ作業者の進行操作性を容易にすると共に作業機体の進行の安定性を図ることができ、かつ、抵抗部材２４は上下調節機構２５により上下調節自在に設けられているので、抵抗部材２４の圃場面Ｍに対しての穿入深さを調節することができ、さらに抵抗部材２４は、後部に向けて開いた二股状部材２４ａ・２４ａにより形成され、良好な抵抗作用を得ることができ、過大な牽引走行を良好に抑制することができる。
【００１９】

[0015]
Since the first embodiment of the present embodiment has the above-described configuration, the operator grips the handle 3, rotates the wheel 4 and the rotating adjuster 6 by driving the engine 2 of the traveling machine body 1, and operates the handle 3.

The second embodiment shown in FIG. 7 shows another example structure. In this case, the rotation axis of the rotary trimming body 6 is arranged in the horizontal direction.
[0020]
The present invention is not limited to the above-described embodiment. For example, the structure of the earth cutting rotor 5 and the number and shape of the pressing surface portions K and D and the through holes F and C of the rotary trimming body 6 and the pressing The size and material of the plate bodies G and E are designed with appropriate changes, and the earth cutting rotor 5 may be composed of a plurality of rotors.

【The invention's effect】
As described above, according to the first aspect of the present invention, the handle is projected from the rear part in the traveling direction of the traveling machine body, the wheel is disposed on one side of the traveling machine body, and the other side of the traveling machine body. since in the traveling direction ahead are disposed a rotary Seiaze body serving as a Kezudo rotor and a wheel provided obliquely downward rotation axis part, operator grips the handle, vehicle body while the handle When traveling along the old fence, the earth cutting rotor provided on the rotating shaft that is diagonally downward and forward in the direction of travel, scrapes the edge of the earth and continuously jumps up on the old iron, and the rotary trimming body rotates and cuts. The soil that has been earthed can be rotationally pressed by the rotary trimming body and trimmed, the machine can be reduced in size and weight, the machine can be transported easily, and the farming work in the mountainous area can be performed. suitable as the result, it is possible to improve the flexibility of use, and the rotating integer A plurality of pressing surface portions are formed at intervals on the outer peripheral portion of the body, and each pressing surface portion has a length extending from the pressing surface portion side at the front position in the rotational direction to the pressing surface of the pressing surface portion at the rear position adjacent thereto. Since the front part of the pressing plate body is arranged, the pressing plate body gradually pressurizes the embankment and presses with the pressing surface part as the rotary trimming body rotates in the direction that promotes the advance of the traveling machine body. A structure in which strong pressure is applied through the plate body, intermittent tightening is performed by the presence of the plurality of pressing surface portions, and tightening is performed on the entire outer peripheral surface of the rotating rectifying body by the presence of the plurality of pressing surface portions. In comparison, the tightening pressure can be increased by reducing the tightening pressure area, and the rivet can be tightened as much as that. By increasing the rotation speed of the rotating tempering body, Slip rotation contact with the heel surface, and the heel surface is smooth and strong by this slip rotation contact. Further, since the through-holes are formed between the above-mentioned pressing surface portions and the pressing plate body is formed of a flexible plate material, the flange surface is further intermittently formed by the through-holes. The pressure can be tightened firmly, and the pressure can be tightened gradually by the flexibility, and the embankment can be gradually tightened while flexing, so that the soil adheres to the outer periphery of the rotating leveling body. The phenomenon can be suppressed, the corner portion between the upper surface and one side surface of the ridge can be clamped well, a good trimming operation can be performed, and a more robust ridge can be obtained.
[0022]
Further, in the invention described in claim 2, since the rotary adjuster is composed of a side adjuster capable of rotating and adjusting one side of the ridge and an upper adjuster capable of rotating and adjusting the upper surface of the ridge. , One side surface of the ridge and the upper surface of the ridge can be rotated and adjusted at the same time, and the pressure can be improved.
