Description

【０００１】
【発明の属する技術分野】
本発明は、畦立作業機及び畦立て方法に係り、詳しくは、耕耘装置により土を盛り上げて成形した畦の土中に施肥することが可能な畦立作業機及び畦立て方法に関する。
【０００２】
【従来の技術】
従来、畦立作業を行いながら施肥を行なう場合、畦立作業をした後に点注や条施肥などにより局所施肥を行なおうとすると、既に成形した畦を崩すおそれがあるので、例えば耕耘作業を行う前に、粒状肥料等を圃場に全面的に散布してからロータリ耕耘装置で耕耘し、土と肥料を混和した状態で、ロータリ耕耘装置の後部に装着した畦立器により畦立作業を行ったり、又は成形された畦の表面にフィルムを被覆し、この被覆されたフィルムの一部を破ってその孔から施肥するか、或いは、苗植付孔を狙って施肥することが行われていた。
【０００３】
【発明が解決しようとする課題】
しかし、前述のように、耕耘作業の前に粒状肥料等を圃場に散布し、次いでロータリ耕耘装置にて耕耘し、土と肥料を混和した状態で、ロータリ耕耘装置の後部に装着した畦立装置により畦立作業をする場合は、粒状肥料等が畦中に全面に散在されるため、肥料が雨で流れたりガスになって空気中に逃げたりして、作物が肥料を吸収する肥料効率が悪くなるという課題があった。また、成畦・フィルム被覆後の施肥孔又は苗植付孔を狙って、局所施肥を行なう手段によると、作業が極めて困難であった。
【０００４】
本発明は、斯かる課題を解決するためになされたもので、その目的とするところは、耕耘装置により土を盛り上げ、畦を成形する場合に、畦が成形完了される前に盛り上げた土中に施肥することのできる畦立作業機及び畦立て方法を提供することにある。
【０００５】
【課題を解決するための手段】
前記目的を達成するため、請求項１記載の発明は、耕耘装置（３）の後部に畦立器（４）を装着し、該耕耘装置（３）により耕耘して盛り上げた土を、前記畦立器（４）により所定形状の畦に成形可能な畦立作業機において、
前記畦立器（４）が、後方に向って下方に傾斜する上面板（４ａ）及び左右の側面板（４ｂ，４ｂ）を有し、
前記上面板（４ａ）の前部位置において該上面板を上方から貫通して配置され、畦が成形完了される前に、前記盛り上げた部分の土中に向けて施肥する施肥ノズルを備えた、ことを特徴とする。
【０００６】
また、請求項２記載の発明は、耕耘装置（３）により耕耘した土を盛り上げ、該盛り上げた土を畦立器（４）により所定形状の畦を成形する畦立て方法であって、
前記畦立器（４）の前部位置で該畦立器（４）の上面板（４ａ）を上方から貫通して配置された施肥ノズル（５）にて前記盛り上げた部分の土中に施肥し、前記施肥ノズル（５）によって土中に形成された軌跡空間を、後方に向って下方に傾斜する上面板（４ａ）及び左右の側面板（４ｂ，４ｂ）を有する前記畦立器（４）により後方から押し固めて、所定形状の畦を成形完了するようにした、ことを特徴とする。
【０００７】
［作用］
以上の発明特定事項により、畦立作業機は、ロータリ耕耘装置（３）等の後部に畦立器（４）を装着し、該ロータリ耕耘装置（３）等により耕耘して盛り上げた土を、前記畦立器（４）により所定形状の畦に成形するもので、この畦が成形完了される前に、前記盛り上げた部分の土中に向けて施肥する施肥ノズル（５）を備えていて、前記畦立器（４）は、施肥ノズル（５）によって土中に形成された軌跡空間を後方から押し固めるので、この押し固められる前の膨軟な土中に施肥することとなり、施肥ノズル（５）に対する土からの走行抵抗が少なく、また強固でくずれにくい畦を成形することが可能となる。
【０００８】
なお、上述カッコ内の符号は、図面と対照するものであって、何ら本発明の発明特定事項を限定するものではない。
【０００９】
【発明の実施の形態】
以下、図面に沿って、本発明の実施の形態について説明する。
【００１０】
図１において、トラクタ１の機体後部に、リンク装置２を介してロータリ耕耘装置３が装着されている。このロータリ耕耘装置３は、耕耘爪３ａの外周面を覆う上部カバー７を有し、該上部カバー７の上方に図示しない施肥タンクが搭載されている。前記トラクタ１の動力は、ＰＴＯ軸（図示せず）からチエンケース８内の伝動チエンを介して前記耕耘爪３ａに伝達され、該耕耘爪３ａが回転される。また、前記ロータリ耕耘装置３の後部には、多連の畦立器４が装着されていて、前記耕耘爪３ａによって耕耘され盛り上げられた土は、トラクタ１の進行に伴いこれら多連の畦立器４によって所定形状の畦に成形される。
【００１１】
前記畦立器４は、図２に示すように、略々コ字形に形成され正面視が下方に開口した上面板４ａと左右の両側面板４ｂ，４ｂを有し、該側面板４ｂ，４ｂは、畦の勾配面を形成するように、上方から下方に向けて左右幅が広くなるように左右略々対称に傾斜して形成され、また前記上面板４ａは、トラクタ１の進行方向の前方から後方に向けて下方に傾斜していて、これら上面板４ａ及び側面板４ｂ，４ｂにより、前記耕耘された土を上面及び左右側面の３方向から成形する。
【００１２】
本発明においては、畦が成形完了される前に、前記盛り上げた部分の土中に向けて施肥する施肥ノズルを備えている。
【００１３】
前記畦立器４の上面板４ａの前部位置には、該上面板４ａを上方から貫通して、１畦につき施肥ノズルとしての２本の施肥管５，５が夫々設けられている。この施肥管５の先端部５ａは、略々直交する方向に後方に向けて屈曲され、次述するように前記畦が成形完了される前に、施肥管５の先端部５ａを通じて畦中に液状、ペースト状、又は粉粒状等の肥料６が噴出されるようになっている。
【００１４】
すなわち、前記ロータリ耕耘装置３の後部に装着された畦立器４は、トラクタ１の進行に伴い前進するが、図３に示すように、耕耘されて盛り上げられた土は、まず畦立器４の自重により前部の上面板４ａと側面板４ｂ，４ｂを介して３方向から成形され、更に前進するに従い、後方に傾斜する上面板４ａが内側下方の土を押圧して押し固め、所定形状の畦が成形完了される。
【００１５】
この場合、畦立器４の前部により成形された部分は、上面板４ａにより押し固められる前の軟らかい状態にあり、この状態で前記施肥管５によって土中に施肥される。そして、この施肥後に施肥管５によって土中に形成された軌跡空間が、上面板４ａにより後方から押し固められ、所定形状の強固な畦が成形完了されることになる。
【００１６】
なお、本実施の形態では、前記畦立器４の上面板４ａに直接施肥管５を取り付けた場合について説明したが、これに限らず、例えばロータリ耕耘装置３の後部に施肥管５を取り付け、この施肥管５をロータリ耕耘装置３の後方でかつ畦立器４の前方位置に配置することも可能であり、この場合にも、畦立器４の上面板４ａにより、施肥管５によって土中に形成された軌跡空間を後方から押し固めることができる。
【００１７】
次に本実施の形態の作用について説明する。
【００１８】
トラクタ１を前進走行させ、ロータリ耕耘装置３の耕耘爪３ａにより耕耘して盛り上げた土を、上面板４ａ及び左右両側面板４ｂ，４ｂを有し、かつ下方に向け開口した多連の畦立器４によって畦が成形されるが、この畦が成形完了される前に、１畦につき夫々２本づつ設けられた施肥管５の先端部５ａから進行方向後方に向けて、連続して畦中に施肥が行なわれる。本実施の形態においては、肥料としては半流動状のペースト肥料が用いられ、このため、ノズル断面積が小さくても肥料詰まりがなく、しかも集中施肥できるので施肥効率が良いという利点を有している。
【００１９】
この場合、畦立器４の上面板４ａは進行方向の前方から後方に向けて下方に傾斜しているので、トラクタ１の前進走行に伴い、畦立器４の上面板４ａが、耕耘されて膨軟になった土を上方から押し固める作用を行なう。このため、畦立器４の前部付近においては、成形された土は軟らかく、前記施肥管５の立上げ部が土から受ける抵抗は少ない。そして、前記施肥管５の立上げ部が土中を通過する際、残した畦中の軌跡空間は畦立器４の上面板４ａにより押潰されて畦中に肥料だけを残し、かつ該上面板４ａにより強固でくずれにくく表面の平滑な畦が成形されることになる。
【００２０】
【発明の効果】
請求項１記載の発明によれば、畦が成形完了される前に、耕耘装置により盛り上げた土中に向けて施肥する施肥ノズルを備えたことにより、押し固められる前の膨軟な土中に施肥することになるので、該施肥ノズルに対する土からの走行抵抗は少なく、また最終的に強固でくずれにくい畦を成形することができる。
【００２１】
請求項２記載の発明によれば、耕耘装置により耕耘した土を盛り上げ、該盛り上げた部分の土中に施肥ノズルにて施肥し、畦立器は前記施肥ノズルによって土中に形成された軌跡空間を後方から押し固めて、所定形状の畦を成形完了するようにしたので、一連の工程で強固で仕上がり精度の良い畦を成形することができる。

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0010]
In FIG. 1, a rotary tiller 3 is attached to the rear part of the tractor 1 via a link device 2. The rotary tiller 3 has an upper cover 7 that covers the outer peripheral surface of the tillage claw 3 a, and a fertilization tank (not shown) is mounted above the upper cover 7. The power of the tractor 1 is transmitted from the PTO shaft (not shown) to the tilling claw 3a via the transmission chain in the chain case 8, and the tilling claw 3a is rotated. Further, a plurality of uprights 4 are attached to the rear portion of the rotary tiller 3, and the soil that has been plowed and raised by the tilling claws 3 a is raised up as the tractor 1 advances. The container 4 is formed into a predetermined shape.
[0011]
As shown in FIG. 2, the upright 4 has an upper surface plate 4a formed in a substantially U shape and opened downward in front view, and left and right side plates 4b, 4b. The upper surface plate 4a is inclined from the front in the direction of travel of the tractor 1 so as to form a sloped surface of the kite so that the lateral width increases from the upper side to the lower side. It is inclined downward toward the rear, and the cultivated soil is formed from the upper surface and the left and right side surfaces by the upper surface plate 4a and the side surface plates 4b and 4b.
[0012]
In the present invention, the fertilizer application nozzle is provided for applying fertilization toward the soil of the raised portion before the mold is completed.
[0013]
Two fertilizer pipes 5 and 5 serving as fertilizer nozzles are provided for each one at the front portion of the top plate 4a of the upright 4 through the top plate 4a from above. The tip portion 5a of the fertilizer tube 5 is bent rearward in a substantially orthogonal direction, and the liquid is passed through the tip portion 5a of the fertilizer tube 5 into the cocoon before the molding is completed as described below. A fertilizer 6 such as paste or powder is ejected.
[0014]
That is, the upright 4 attached to the rear portion of the rotary tiller 3 moves forward as the tractor 1 advances. As shown in FIG. Is formed from three directions through the front upper surface plate 4a and the side surface plates 4b and 4b by its own weight, and as it further advances, the upper surface plate 4a inclined rearward presses and compresses the soil on the inner lower side to form a predetermined shape. The mold is completed.
[0015]
In this case, the portion formed by the front portion of the upright 4 is in a soft state before being compressed by the upper surface plate 4a, and in this state, fertilized in the soil by the fertilizer tube 5. The trajectory space formed in the soil by the fertilizer pipe 5 after this fertilization is pressed and compacted from the rear by the upper surface plate 4a, and the formation of a strong rod having a predetermined shape is completed.
[0016]
In addition, in this Embodiment, although the case where the fertilizer pipe 5 was directly attached to the upper surface board 4a of the said stand 4 was demonstrated, not only this but the fertilizer pipe 5 is attached to the rear part of the rotary tiller 3, for example, It is also possible to arrange the fertilizer pipe 5 at the rear of the rotary tiller 3 and at the front position of the vertical unit 4. In this case as well, the fertilizer pipe 5 allows the fertilizer pipe 5 to submerge the soil. The trajectory space formed in can be pressed from behind.
[0017]
Next, the operation of this embodiment will be described.
[0018]
Multiple uprights having an upper surface plate 4a and left and right side surface plates 4b, 4b, which are made to move forward by the tractor 1 and are plowed by the tilling claws 3a of the rotary tiller 3, and open downward. 4 is formed, but before the completion of the forming, 2 pieces of fertilizer pipes 5 are provided for each 1 piece from the distal end portion 5a of the fertilizer tube 5 toward the rear in the traveling direction and continuously in the bowl. Fertilization is performed. In the present embodiment, a semi-fluid paste fertilizer is used as the fertilizer.Therefore, there is no fertilizer clogging even if the nozzle cross-sectional area is small, and there is an advantage that fertilization efficiency is good because concentrated fertilization is possible. Yes.
[0019]
In this case, since the upper surface plate 4a of the upright 4 is inclined downward from the front to the rear in the traveling direction, the upper surface plate 4a of the upright 4 is cultivated as the tractor 1 moves forward. Performs the action of pressing the softened soil from above. For this reason, in the vicinity of the front part of the upright 4, the molded soil is soft, and the rising portion of the fertilizer pipe 5 receives less resistance from the soil. Then, when the rising portion of the fertilizer pipe 5 passes through the soil, the trace space in the remaining culm is crushed by the upper surface plate 4a of the rectifier 4, leaving only the fertilizer in the culm, and The face plate 4a forms a ridge that is strong and difficult to break, and has a smooth surface.
[0020]
【The invention's effect】
According to the first aspect of the present invention, by providing the fertilizer nozzle for fertilizing the soil that has been raised by the tillage device before the completion of the molding of the straw, the soft soil before being compacted can be provided in the soft soil. Since fertilization is performed, the running resistance from the soil with respect to the fertilization nozzle is small, and finally a strong and difficult to break can be formed.
[0021]
According to invention of Claim 2, the soil cultivated by the tillage device is piled up, fertilized with a fertilizer nozzle in the soil of the raised portion, and the upright is a trajectory space formed in the soil by the fertilizer nozzle. Is pressed from the rear to complete the formation of the predetermined shape of the ridge, so that the ridge can be formed with a strong and accurate finish in a series of steps.
