This makes it possible to cultivate uniformly across the left and right cultivating widths.

本実施の形態の耕耘機Ｙについて以下説明する。
左右一対の走行車輪１の後方には駆動軸２で回転する耕耘爪３と、耕耘爪３の上方を覆う耕耘カバー４とを設け、走行車輪１の上方にはエンジン５と伝動ケース６とを備える走行車体Ｆ設け、走行車体Ｆの後部から斜め後方に向かって主フレーム７を延設し、主フレーム７の後端部から操作ハンドル８を形成している。 The cultivator Y according to the present embodiment will be described below.

An engine 5 and a transmission case 6 are disposed above the traveling wheels 1. The traveling vehicle body F is provided, the main frame 7 is extended obliquely rearward from the rear portion of the traveling vehicle body F, and the operation handle 8 is formed from the rear end portion of the main frame 7.

駆動軸２は伝動ケース６内から進行方向gの左右両外側に向かってそれぞれ突出して形成すると共に、左右内側の内側駆動軸２ａと左右外側の外側駆動軸２ｂとから構成している。内側駆動軸２aと外側駆動軸２bは同一横軸心上に設けると共に、それぞれ反対方向に正逆転する構成としている。すなわち、エンジン５から伝動ケース６内の伝動機構Ｈを伝わった動力は内側駆動軸２ａの設けた伝動スプロケット１０に伝動して内側駆動軸２ａが進行方向ｇと反対側、すなわち回転方向ｍに向かって常時逆転する構成である。また、外側駆動軸２はその回転方向を内側駆動軸２ａとは反対側の正転方向ｍに向かって回転すべく伝動ケース６内にカウンタギア１１等を備える回転方向変更伝動部ｋを設けている。なお、ｊ１は高速、ｊ２は低速にチェンジするギアでシフトレバー９でチェンジする。   The drive shaft 2 is formed to project from the inside of the transmission case 6 toward the left and right outer sides in the traveling direction g, and is composed of an inner drive shaft 2a on the inner left and right sides and an outer drive shaft 2b on the outer left and right sides. The inner drive shaft 2a and the outer drive shaft 2b are provided on the same horizontal axis and are configured to rotate forward and backward in opposite directions. That is, the power transmitted from the engine 5 to the transmission mechanism H in the transmission case 6 is transmitted to the transmission sprocket 10 provided on the inner drive shaft 2a so that the inner drive shaft 2a is directed in the direction opposite to the traveling direction g, that is, in the rotational direction m. Thus, the configuration is always reversed. Further, the outer drive shaft 2 is provided with a rotation direction change transmission section k provided with a counter gear 11 and the like in the transmission case 6 so that the rotation direction thereof rotates in the forward rotation direction m opposite to the inner drive shaft 2a. Yes. Note that j1 is a high-speed gear and j2 is a low-speed gear that is changed by the shift lever 9.

図２は耕耘作業時の耕耘爪３の配列を示したものであるが、内側駆動軸２ａには先端部が左右外側に向いている複数（本実施例では３本）の耕耘爪３を横方向に設定間隔ずらして取り付けている。そして、最も内側の耕耘爪３ａはその途中を湾曲し、最も外側の耕耘爪３ｂの途中部は真っ直ぐに構成している。そのため、耕耘爪３ａが圃場を左右内側からよく土を掘り起こして左右外側に排出することができる。また、外側駆動軸２ｂには先端部が左右内側に向いている複数の耕耘爪３ｃを横方向に設定間隔で取り付けている。   FIG. 2 shows an arrangement of the tilling claws 3 at the time of tillage work. A plurality (three in this embodiment) of the tilling claws 3 whose front end portions are directed to the left and right sides are laterally arranged on the inner drive shaft 2a. Installed at a set interval in the direction. The innermost tillage claw 3a is curved in the middle thereof, and the middle part of the outermost tillage claw 3b is configured straight. Therefore, the tilling claw 3a can dig up the soil well from the left and right inner sides and discharge it to the left and right outer sides. Further, a plurality of tilling claws 3c whose front end portions are directed to the left and right inner sides are attached to the outer drive shaft 2b in the horizontal direction at set intervals.

耕耘カバー４は左右中央部に設ける開閉調節機構１１の調節により左右外側を上下方向に移動できる構成としている。すなわち、耕耘作業時は図２に示すように耕耘爪３の上方を覆う状態とし、畝立て作業時には耕耘カバー４の左右外側を図３に示すように開放する。また、外側駆動軸２ｂは内側駆動軸２ａに対して脱着可能に構成しており、畝立て作業時には取り外す構成としている。   The tillage cover 4 is configured to be movable in the vertical direction on the left and right outer sides by adjustment of the opening / closing adjustment mechanism 11 provided at the left and right center portion. That is, during the tilling operation, the upper portion of the tilling claw 3 is covered as shown in FIG. 2, and the right and left outer sides of the tilling cover 4 are opened as shown in FIG. Further, the outer drive shaft 2b is configured to be detachable from the inner drive shaft 2a, and is configured to be removed during the erecting work.

１３は耕耘作業時に耕耘深さを調節する尾輪で尾輪調節ハンドル１４で上下移動調節可能に構成している。そして、側面視で耕耘爪３の回転軌跡ｄ内に入り込むよう構成することで耕耘機Ｙ全体の前後長を短く構成することができる。尾輪１３の後方には耕耘機Ｙのダッシングを防止する抵抗棒１５を設けている。そして、抵抗棒１５の後方には耕耘カバー４に取り付けたゴム垂れ１６を設けている。   Reference numeral 13 denotes a tail wheel that adjusts the tilling depth during the tilling operation, and can be adjusted up and down by the tail wheel adjusting handle 14. And the front-back length of the whole tillage machine Y can be comprised short by comprising so that it may enter in the rotation locus | trajectory d of the tilling nail | claw 3 by a side view. A resistance rod 15 for preventing the cultivator Y from dashing is provided behind the tail wheel 13. A rubber sag 16 attached to the tillage cover 4 is provided behind the resistance bar 15.

次に畝立て作業と耕耘作業について説明する。
畝立て作業時には図３に示すように耕耘爪３ｃを取りつけている外側駆動軸２ｂを取り外し、耕耘カバー４の左右両側を上方に移動して開放状態とする。また、尾輪１３及び抵抗棒１５は使用しない状態にセットする。そして、高速ギアｊ１にして耕耘作業を開始すると耕耘爪３ａ及び３ｂは逆転方向ｎに回転する。すると、走行する圃場面Ｗの土は耕耘爪３ａ及び３ｂの作用で掘り起こされると共に左右両側ｒに向かって掘り起こした土を跳ね上げることで走行する圃場Ｗの両側に畝Ｕが形成される。 Next, the uprighting work and the tilling work will be described.
As shown in FIG. 3, the outer drive shaft 2b to which the tillage claw 3c is attached is removed and the left and right sides of the tillage cover 4 are moved upward to bring them into an open state. Further, the tail wheel 13 and the resistance rod 15 are set in a state where they are not used. When the cultivation work is started with the high speed gear j1, the cultivation claws 3a and 3b rotate in the reverse direction n. Then, the soil of the traveling farm scene W is dug up by the action of the tilling claws 3a and 3b, and the fence U is formed on both sides of the running farm field W by jumping up the soil dug up toward the left and right sides r.

耕耘作業時には耕耘爪３ｃを取り付けた外側駆動軸２ｂを内側駆動軸２ａに取り付け、耕耘カバー４を下方位置に移動し、尾輪及び抵抗棒１５を所望の位置にセットする。
低速ギアｊ２にセットし耕耘作業が開始されると外側駆動軸２ｂの耕耘爪３ｃは正転方向ｍへ回転し、内側駆動軸２ａの耕耘爪３ａと３ｂは逆転方向ｎへ回転する。そして、尾輪１３は走行する圃場面に設置しながら回転する。そのため、ダッシングを防止しながら耕耘作業を行なうことができる。また、抵抗棒１５は圃場内に突入して耕耘機Ｙの進行を妨げることでさらにダッシングを防止することができる。 At the time of tillage work, the outer side drive shaft 2b to which the tillage claw 3c is attached is attached to the inner side drive shaft 2a, the tillage cover 4 is moved to the lower position, and the tail wheel and the resistance rod 15 are set at desired positions.
When the plowing operation is started by setting to the low speed gear j2, the tilling claws 3c of the outer drive shaft 2b rotate in the normal rotation direction m, and the tilling claws 3a and 3b of the inner drive shaft 2a rotate in the reverse rotation direction n. The tail wheel 13 rotates while being installed in a traveling farm scene. Therefore, tillage work can be performed while preventing dashing. Further, the resistance bar 15 can enter the field and prevent the tiller Y from proceeding, thereby further preventing dashing.

耕耘爪３ａと３ｂは左右内側の土を掘り起こしながら、掘り起こした土を左右外側に向かって移送する一方、耕耘爪３ｃは左右外側の土を掘り起こしながら、掘り起こした土を左右内側に向かって移送することで左右両側耕耘幅にわたって均一に耕耘できる。   While the tilling claws 3a and 3b dig up the left and right inner soils, the digging soil 3c moves the left and right outer sides while the tilling claws 3c dig up the left and right outer soils and transfer the dug up soil toward the left and right inner sides. This makes it possible to cultivate uniformly across the left and right cultivating widths.

また、尾輪１３及び抵抗棒１５の後方にゴム垂れを設けることで、尾輪１３及び抵抗棒１５作用で圃場面にできた跡をならして消すことができ、耕耘作業後の圃場面の見栄えを向上させることができる。   In addition, by providing a rubber sag behind the tail wheel 13 and the resistance rod 15, it is possible to erase the traces made in the farm scene by the action of the tail wheel 13 and the resistance rod 15, and to remove the field scene after the plowing work. The appearance can be improved.

次に図６及び図７に基づいて耕耘機の別実施例について説明する。
図６と図７は尾輪１３と整地用の均平板２０とが同一の高さ調節機構２１で上下できる構成とすると共に尾輪１３を回動軸１３ｂを支点に尾輪の支持軸１３ａを回動する構成としている。すなわち、図６と図７は尾輪１３を使用しない状態を示す図であり、固定部材１３ｃで尾輪の支持軸１３ａの位置を固定している。また１３ａは受部１３ｄに対して上下移動調節できる構成としている。 Next, another embodiment of the field cultivator will be described with reference to FIGS.
6 and 7, the tail wheel 13 and the leveling flat plate 20 can be moved up and down by the same height adjusting mechanism 21, and the tail wheel 13 is supported by the support shaft 13 a of the tail wheel with the pivot shaft 13 b as a fulcrum. It is set as the structure which rotates. 6 and 7 show a state in which the tail wheel 13 is not used, and the position of the support shaft 13a of the tail wheel is fixed by the fixing member 13c. Further, 13a is configured to be able to adjust the vertical movement relative to the receiving portion 13d.

そして、均平板２０は高さ位置調節機構２３で調節できる構成である。
この構成により、均平板２０と尾輪１３とを一体にすることができるため、耕耘機作業時の上下調節がしやすくなる。 The flat plate 20 can be adjusted by the height position adjusting mechanism 23.
With this configuration, the leveling plate 20 and the tail wheel 13 can be integrated with each other, so that the vertical adjustment during the tilling work can be easily performed.
