上記技術思想に基づいて具体的に構成された実施の形態について以下に図面を参照しつつ説明する。
耕耘作業機１は、作業車両に取付けた状態の側面図を図１に示すように、チェーン伝動部２ａと連結する耕耘軸２に設けた後述の複数の耕耘爪３…よって一定半径で圃場に耕耘作用する粉砕構成の耕耘部Ａと、その両側部および後部を覆うカバー１ａ，１ｂ等を備えて構成され、作業車両１１からロワーリンク１２、トップリンク１３等によって昇降可能に連結し、ＰＴＯ軸１４から回転動力を受ける。 Embodiments specifically configured based on the above technical idea will be described below with reference to the drawings.
As shown in FIG. 1, a side view of the tilling work machine 1 attached to the work vehicle is provided on the field with a fixed radius by a plurality of tilling claws 3 to be described later provided on the tilling shaft 2 connected to the chain transmission portion 2a. A plowing portion A having a pulverizing configuration with plowing action and covers 1a, 1b and the like covering both sides and a rear portion thereof are connected to the work vehicle 11 so as to be movable up and down by a lower link 12, a top link 13, etc. 14 receives rotational power.

また、耕耘作業とともに畝立作業をするために、畝立装備の耕耘作業機の側面図を図２に示すように、耕耘作業機１の後部カバー１ｂを引上げて畝の両側面と上面の整形を合わせて行う畝立機１ｃを装着可能に構成する。 Further, in order to perform the upright work together with the tillage work, as shown in FIG. 2, a side view of the tillage work machine equipped with the upright equipment, the rear cover 1 b of the tillage work machine 1 is pulled up to shape both side surfaces and the upper surface of the work. The vertical machine 1c, which is performed together, is configured to be mountable.

粉砕構成の耕耘部Ａは、耕耘軸２の耕耘軸線について展開した爪配列展開図を図３に示すように、耕耘幅方向に延びる耕耘軸２から放射状に設けた複数の鞘状のホルダ２ｂ…に交換可能に耕耘爪３…を設ける。 As shown in FIG. 3, the cultivating part A having a pulverized configuration has a plurality of sheath-like holders 2 b provided radially from the cultivating shaft 2 extending in the cultivating width direction as shown in FIG. 3. The tilling claws 3 are provided in a replaceable manner.

各ホルダ２ｂ…は、耕耘軸２の軸線方向について一定ピッチＰで隣接する回転位置に配置する。
耕耘爪３は、各ホルダ２ｂ…を介して放射方向に延びる腕部３ａとその末端から屈曲し、所定の作用幅Ｗで円弧状に延出して圃場に耕耘作用する爪部３ｂとから構成する。 Each holder 2b ... is arrange | positioned in the rotational position which adjoins with the fixed pitch P about the axial direction of the tilling axis | shaft 2. As shown in FIG.
The tilling claw 3 is composed of an arm portion 3a extending in the radial direction via each holder 2b, and a claw portion 3b that is bent from the end thereof, extends in an arc shape with a predetermined action width W, and plows on the field. .

耕耘爪３について詳細に説明すると、爪部３ｂは、腕部３ａの回転によってその片側方の作用幅Ｗの位置まで耕土を片側方に寄せる傾斜姿勢に形成した上で、耕耘軸２の軸線方向に隣接する回転位置の耕耘爪３との間でそれぞれの作用幅Ｗの少なくとも一部が互いに重なるように、ホルダ２ｂ…の隣接ピッチＰに対して各爪部３ｂの作用幅Ｗを大きく形成する。 The tilling claw 3 will be described in detail. The claw portion 3b is formed in an inclined posture in which the cultivation soil is moved to one side by the rotation of the arm portion 3a to the position of the one side operation width W, and then the axial direction of the tilling shaft 2 The action width W of each claw portion 3b is formed larger than the adjacent pitch P of the holders 2b... So that at least a part of each action width W overlaps with the tilling claw 3 at the rotation position adjacent to the holder c. .

上記構成の耕耘部Ａは、耕耘軸２が回転駆動されると、耕耘軸２から半径方向に延びる複数の腕部３ａ…が一体に回転駆動されて爪部３ｂがそれぞれ周回動作し、腕部３ａから続く爪部３ｂの基端位置が圃場に耕耘作用し、回転に連れてその側方に次第に作用位置を移動して腕部３ａの回転位置から作用幅Ｗの位置まで耕土を片側方に寄せるように圃場を耕耘し、耕耘作用位置が隣接回転位置の耕耘爪３の作用範囲まで及ぶ。 When the tilling shaft 2 is rotationally driven, the tiller portion A having the above-described configuration is driven to rotate integrally with the plurality of arm portions 3a extending in the radial direction from the tilling shaft 2, and the claw portions 3b each rotate. The base end position of the claw portion 3b that continues from 3a is plowed on the field, and gradually moves to the side as it rotates to move the cultivated soil to one side from the rotation position of the arm portion 3a to the position of the action width W. The field is cultivated so that it approaches, and the cultivating action position reaches the action range of the cultivating claw 3 at the adjacent rotation position.

このように、互いに隣接する回転位置の２つの耕耘爪３，３の少なくとも一部の作用幅Ｗが互いに重なるように構成することにより、その重なり範囲では両方の耕耘爪３，３の爪部３ｂ，３ｂが圃場を耕耘して細かく砕土することができる。 In this way, by configuring the working width W of at least part of the two tilling claws 3 and 3 at the rotation positions adjacent to each other to overlap each other, the claws 3b of both the tilling claws 3 and 3 in the overlapping range. , 3b can cultivate the field and finely pulverize the soil.

この場合において、耕耘爪３…は、隣接回転位置の耕耘爪３との間で耕耘軸２について互いに異なる周回角度位置として互いに回転円周方向にずらした位置に配置することで、耕耘爪間の接触を防止して、耕耘作用を確保することができる。 In this case, the tilling claws 3 are arranged at positions shifted from each other in the rotational circumferential direction as different rotation angle positions with respect to the tilling shaft 2 with respect to the tilling claws 3 at the adjacent rotation positions. Contact can be prevented to ensure tillage.

（対向耕耘爪群）
また、回転位置が互いに隣接する複数の耕耘爪３…を単位として、その耕耘作用範囲の中央位置に耕土が集中するように対向姿勢に配置して対向耕耘爪群Ｇを形成し、耕耘部Ａの耕耘全幅を複数の対向耕耘爪群Ｇ…に分けることにより、耕耘跡の耕耘盛土による凹凸を平均化することができる。 (Opposite tillage nail group)
Further, with the plurality of tilling claws 3... Adjacent to each other as rotation units, the opposing tilling claws group G is formed by arranging them in an opposing posture so that the soil is concentrated at the center position of the cultivation action range. By dividing the total tillage width into a plurality of opposing tilling nail groups G, unevenness due to tilling embankment of tilling marks can be averaged.

図示例では、耕耘軸２の軸線方向に一定ピッチで隣接する４５か所の回転位置に５２個の耕耘爪３…を配置し、軸端から４か所または３か所ずつ、爪部３ａの姿勢を揃えたブロックを形成し、隣接する２つのブロックが対向した対向耕耘爪群Ｇを構成して耕耘軸２の複数位置に配置する。 In the illustrated example, 52 tilling claws 3 are arranged at 45 rotational positions adjacent to each other at a constant pitch in the axial direction of the tilling shaft 2, and four or three places from the end of the shaft are arranged on the pawl portion 3a. Blocks having a uniform posture are formed, and an opposing tilling claw group G in which two adjacent blocks are opposed to each other is formed and arranged at a plurality of positions on the tilling shaft 2.

また、互いに隣接する２つの対向耕耘爪群Ｇ，Ｇは、共通の回転位置についてそれぞれの耕耘爪３，３を重複配置することにより、耕耘部Ａの耕耘全幅を分割耕耘可能に構成する。 Moreover, the two opposing tilling nail groups G and G adjacent to each other are configured such that the entire tilling width of the tilling portion A can be divided and tilled by overlappingly arranging the tilling claws 3 and 3 at a common rotational position.

さらに、各耕耘爪３…は、全耕耘爪の周回配置図を図４に示すように、耕耘軸２の全周回域において、すべてを互いに異なる等分周角度位置に配置する。但し、同図において、各耕耘爪は、耕耘軸２の軸端からの各回転位置の番号（「Ｒ」は同一回転位置に重複配置の耕耘爪３を示す）によって特定し、また、角度位置は、それぞれの腕部３ａ…を固定するホルダ２ｂの位置である。 Further, each of the tilling claws 3 is arranged at equally divided angular positions different from each other in the entire turning area of the tilling shaft 2 as shown in FIG. However, in the same figure, each tilling claw is specified by the number of each rotation position from the shaft end of the tillage shaft 2 ("R" indicates the cultivation claws 3 arranged in duplicate at the same rotation position), and the angular position Is the position of the holder 2b which fixes each arm part 3a ....

具体的に説明すると、ブロック単位の耕耘爪の側面図を図５（ａ）〜（ｄ）に示すように、軸端のブロック１のＮｏ１〜Ｎｏ４からブロック２のＮｏ５〜Ｎｏ８、ブロック３のＮｏ８Ｒ〜Ｎｏ１０、ブロック４のＮｏ１１〜Ｎｏ１３の順に隣接し、同様にして他の軸端のブロック１６まで、順次、全耕耘爪３…を互いに異なる等分周角度位置に配置する。 Specifically, as shown in FIGS. 5A to 5D, the side view of the block unit tillage nail is from No1 to No4 of the block 1 at the shaft end to No5 to No8 of the block 2 and No8R of the block 3. .. To No. 10 and No. 11 to No. 13 of the block 4, and similarly, all tillage claws 3... Are sequentially arranged at different equally divided angular positions up to the block 16 at the other shaft end.

また、ブロック１およびブロック２のＮｏ１〜Ｎｏ８の耕耘爪３…によって構成される対向耕耘爪群Ｇに対して、ブロック３およびブロック４のＮｏ８Ｒ〜Ｎｏ１３の耕耘爪３…によって構成される対向耕耘爪群Ｇは、Ｎｏ８とＮｏ８Ｒの耕耘爪３，３を共通の回転位置として隣接し、以下同様にして対向耕耘爪群Ｇを隣接構成する。 Moreover, with respect to the counter tilling nail group G constituted by the No. 1 to No. 8 tilling claws 3 of the block 1 and the block 2, the opposite tilling claws constituted of the No. 8R to No. 13 tilling claws 3 of the block 3 and the block 4 are arranged. The group G is adjacent to the No. 8 and No. 8R tilling claws 3 and 3 as a common rotational position, and the opposite tilling claws group G is adjacently configured in the same manner.

次に、耕耘爪の作用幅について、図６の耕耘部構成例の爪配列展開図と耕耘跡の断面図により比較説明すると、標準的な耕耘部構成例は、耕耘軸線展開による爪配列展開図を図６（ａ）に示すように、爪部３ｂの作用幅Ｗ0が隣接ピッチＰ0以下であり、これを比較基準として、図６（ｂ）の爪配列展開図に示す粉砕構成例は、隣接ピッチＰをＰ0／２とすることで土塊が半分になり、作用幅Ｗを隣接ピッチＰの２倍長とすることで２倍の耕耘作用を有することから、耕耘する土塊を標準ロータリ比１／４に砕土することができる。この粉砕構成例による耕耘跡は、その断面図を図６（ｃ）に示すように、複数の対向耕耘爪群Ｇ…と対応する耕耘盛土によって凹凸を小さくすることができる。 Next, the action width of the tilling nail will be described in comparison with the nail arrangement development view of the cultivation part configuration example in FIG. 6 and the cross-sectional view of the tilling trace. 6 (a), the action width W0 of the claw portion 3b is equal to or less than the adjacent pitch P0. With this as a reference, the crushing configuration example shown in the claw arrangement development view of FIG. By setting the pitch P to P0 / 2, the soil mass is halved, and by setting the action width W to be twice as long as the adjacent pitch P, the soil mass to be cultivated is reduced to the standard rotary ratio 1 / 4 can be crushed. As shown in FIG. 6C, the unevenness of the tilling trace according to this pulverization configuration example can be reduced by the tilling embankment corresponding to the plurality of opposing tilling nail groups G.

具体例で比較すると、耕耘部のバリエーションの爪配列部分展開図を図７（ａ〜ｄ）に示すように、隣接ピッチＰ0＝６０mm、作用幅Ｗ0＝60mmの標準ロータリを基準に、隣接ピッチＰをＰ0の半分の３０mmとし、作用幅Ｗを６０，９０，１２０，１５０mmのバリエーション、すなわち、２，３，４，５ピッチ幅とすることで、標準ロータリ比が、１／４、１／６、１／８、１／１０の砕土効果を実現することができる。 Compared with specific examples, as shown in FIG. 7 (a to d), the nail arrangement partial development view of the variation of the tillage portion is based on the standard rotary with the adjacent pitch P0 = 60 mm and the action width W0 = 60 mm. Is 30 mm, which is half of P0, and the working width W is 60, 90, 120, 150 mm, that is, 2, 3, 4, 5 pitch width, so that the standard rotary ratio is 1/4, 1/6. 1/8, 1/10 can be achieved.

上記のほかに、隣接ピッチＰを２０mmとし、作用幅Ｗを４０、６０、１００mmのバリエーションについては、標準ロータリ比が、１／６、１／９、１／１５の砕土効果を実現することができる。 In addition to the above, for a variation in which the adjacent pitch P is 20 mm and the working width W is 40, 60, 100 mm, it is possible to achieve a ground breaking effect with standard rotary ratios of 1/6, 1/9, 1/15. it can.

次に、複数回転構成の場合の耕耘爪の耕耘作用を図１０の軸線展開配列図によって比較説明すると、標準ロータリの耕耘軸線展開による爪配列展開図を図１０（ａ）に示すように、標準ロータリ構成の爪部３ｂの作用幅Ｗ0が隣接ピッチＰ0相当で２回作用の耕耘を比較基準として、図１０（ｂ）に示すように、隣接ピッチＰをＰ0／２とすることで土塊が半分になり、さらに、作用幅Ｗを隣接ピッチＰの２倍長とすることで４回作用の耕耘が可能となる。 Next, the tilling action of the tilling nail in the case of a multi-rotation configuration will be compared and explained with reference to the axial development arrangement diagram of FIG. 10. As shown in FIG. As shown in FIG. 10 (b), when the action width W0 of the claw portion 3b of the rotary configuration is equivalent to the adjacent pitch P0 and the double-action tillage is used as a comparison reference, the adjoining pitch P is set to P0 / 2 as shown in FIG. Furthermore, when the action width W is twice as long as the adjacent pitch P, the four-time tillage is possible.

複数回転構成のバリエーションについて、隣接ピッチが共通の具体例で比較すると、標準ロータリは、その爪配列部分図を図１１（ａ）に示すように、隣接ピッチＰ0＝６９mm、作用幅Ｗ0＝６９mmの２回作用によって耕耘し、これに対し、作用幅Ｗが隣接ピッチＰの２倍、３倍の爪配列部分図を図１１（ｂ、ｃ）に示すように、それぞれ、４回、６回作用の耕耘が可能となる。 Comparing variations of multiple rotation configurations with specific examples in which the adjacent pitch is common, the standard rotary has a claw arrangement partial view as shown in FIG. 11 (a), with an adjacent pitch P0 = 69 mm and an action width W0 = 69 mm. Plowing is performed twice, while the action width W is twice or three times the adjacent pitch P. As shown in FIG. 11B and FIG. It becomes possible to plow.

（フランジ式構成）
次に、耕耘軸２の各回転位置のフランジを介してそれぞれ複数の耕耘爪を設けたフランジ式構成の場合について、耕耘爪の耕耘作用を標準構成と比較して説明すると、標準ロータリは、その爪配列展開図を図１２（ａ）に示すように、爪部３ｂの作用幅Ｗ0が隣接ピッチＰ0の半分の２本の耕耘爪３，３を設けた場合に、１回作用の耕耘を行う。
また、各フランジ２ｃに４本、６本の耕耘爪３…を設けた場合は、それぞれ２回作用、３回作用の耕耘を行う。 (Flange type configuration)
Next, in the case of a flange-type configuration in which a plurality of tilling claws are provided via flanges at respective rotational positions of the tillage shaft 2, the tilling action of the tilling claws will be described in comparison with the standard configuration. As shown in FIG. 12 (a), the nail arrangement development view shows that when two tilling claws 3 and 3 having an action width W0 of the nail portion 3b half of the adjacent pitch P0 are provided, a single action tillage is performed. .
In addition, when four or six tilling claws 3 are provided on each flange 2c, two-time and three-time tilling is performed.

上記標準ロータリに対して、爪配列例１の展開図を図１２（ｂ）に示すように、作用幅Ｗを隣接ピッチＰの１倍長とすることで２回作用となり、標準ロータリ比が１／２の耕耘が可能となる。
また、各フランジ２ｃに４本または６本の耕耘爪３…を設けた場合は、４回作用、６回作用の耕耘が可能となる。 As shown in FIG. 12 (b), the developed view of the claw arrangement example 1 with respect to the standard rotary is operated twice by setting the action width W to be 1 time longer than the adjacent pitch P, and the standard rotary ratio is 1 / 2 tillage is possible.
In addition, when four or six tilling claws 3 are provided on each flange 2c, four-time and six-time tilling is possible.

続いて、爪配列例２の展開図を図１２（ｃ）に示すように、作用幅Ｗを隣接ピッチＰの１．５倍長とすることで３回作用の耕耘が可能となり、標準ロータリ比が１／３の耕耘が可能となり、各フランジ２ｃに４本の耕耘爪３…を設けた場合は６回作用、６本の耕耘爪３…を設けた場合は９回作用の耕耘が可能となる。 Subsequently, as shown in a developed view of the nail arrangement example 2 in FIG. 12 (c), the action width W is set to 1.5 times the adjacent pitch P, so that the three-time tillage is possible, and the standard rotary ratio 1/3 can be cultivated, and when four tilling claws 3 are provided on each flange 2c, six times of action can be achieved, and when six tilling claws 3 are provided, nine times of tilling are possible.
