Description

【0001】
【産業上の利用分野】
本発明は、ロータリ耕耘装置の耕耘作業速度を速くできる耕耘方法に関する。
【0002】
【従来の技術】
従来からトラクターの後部に付設するロータリ耕耘装置は、耕耘爪軸をチェーンケースとサイドサポートの下部の間に横架して、該耕耘爪軸の外周に多数の耕耘爪を植設して、該耕耘爪軸を回転させて耕耘作業を行う。
この耕耘爪軸に耕耘爪を固定する構成としては、耕耘爪軸の外周上において、螺旋状に爪ホルダーを所定間隔を開けて突設し、該爪ホルダーに耕耘爪を右向きまたは左向きに湾曲方向を変えて装着し、非耕耘部分ができないように、耕耘爪と耕耘爪の間の幅方向の間隔をできるだけ小さくして装着しており、ロータリ耕耘装置の耕耘幅内では、耕耘爪による非耕耘領域がないようにしていた。
【0003】
【発明が解決しようとする課題】
このような従来のロータリ耕耘装置では、非耕耘部分ができないようにするために、耕耘爪軸上には多数の耕耘爪を装着しなければならず、重量が増加するばかりでなく、耕耘爪が多いので、土壌に切り込む時の耕耘抵抗も大きくなり、ロータリを回転させるための駆動力も大きくする必要があった。
また、作業を早く終わらせるために、耕耘作業時の走行速度を上げれば、耕耘ピッチが粗くなり土塊が大きくなり過ぎることがあり、これを防止するためにロータリの回転速度を上げると、負荷が大きくなり、耕耘速度を速めるには限界があったのである。
そこで、本発明は、ロータリ耕耘装置の耕耘爪の取付構成を改良して、耕耘爪軸の回転数は従来のままでも、走行速度を上げられ良好な耕耘作業ができる耕耘方法を提供しようとするのである。
【0004】
【課題を解決するための手段】
上記課題を解決するために本発明は、次の如く構成したものである。
耕耘爪軸12に対して直角方向の同一平面に、複数本の耕耘爪13を付設して耕耘爪列を構成し、該耕耘爪列を複数列配置し、それぞれの耕耘爪列の各耕耘爪13を左または右に湾曲させ、互いに向かい合う耕耘爪13の先端の間隔の間に、切断刃17を固設し、該切断刃17は上部を直線状に構成して、下部は後方に湾曲させて、側面視において切断刃17の下部が耕耘爪13の回転軌跡Aの前部でオーバーラップすべく配置し、該耕耘爪軸12上の両側の耕耘爪列の幅L1と、中央側の耕耘爪列の幅L2の合計は、ロータリ耕耘装置の耕耘幅の70〜90パーセントとし、耕耘爪列と耕耘爪列の間の耕耘爪13の非作用部分は、耕耘爪13の反転力が及んで耕耘され、更に前記切断刃17で土塊を切断しながら耕耘するものである。
【0005】
【作用】
このような手段を用いることによって、次のような作用を行うものである。
同じ耕耘幅のロータリ耕耘装置であっても、耕耘爪の取付本数が少なくなって、重量が減少し、しかも、耕耘爪が直接作用する幅も狭くなり、耕耘抵抗が小さくなって従来よりも高速で耕耘できることになる。
そして、耕耘爪の湾曲方向が同一平面で左右方向にあり、また、直接切り込まない土壌の部分であっても耕耘爪による反転した時の力が伝わり、反転されて、土壌は均平に耕耘される。
【0006】
【実施例】
本発明の解決すべき課題及び構成は以上の如くであり、次に添付の図面に示した本発明の一実施例を説明する。
図1はロータリ耕耘装置の側面図、 図2は同じく平面図一部断面図、 図3は耕耘爪軸の展開図、 図4は耕耘爪軸に装着する耕耘爪列の幅を変更した実施例の平面図一部断面図、 図5は一列に6本耕耘爪を配設するロータリの側面図、 図6は一列に4本耕耘爪を配設するロータリの後面図、 図7は同じく側面図である。
【0007】
トラクタに装着するサイドドライブ型のロータリ耕耘装置の実施例について、図1、図2より説明する。
ロータリ耕耘装置は前後方向中央にギアボックス1を配置して、該ギアボックス1より前方に入力軸2を突出し、該入力軸2にユニバーサルジョイントやドライブ軸を介してトラクタのPTO軸と連結して動力を伝えるようにしている。
前記ギアボックス1側面より両側方にビーム3・3を突出し、該ギアボックス1両側に支持プレート4・4を固設し、該支持プレート4・4の前端にはロアリンクを枢結するピンを突設し、後端にはデプスフレーム5の前端を枢支し、更に、支持プレート4・4の前側部とマスト7の間に支持ステー6を介装し、該マスト7の前端にトップリンクの枢結部を構成している。
【0008】
前記ビーム3・3の外側端に、チェーンケース10の上部とサイドサポートの上部が固設され、該チェーンケース10の下部とサイドサポートの下部の間に耕耘爪軸12が横架され、該耕耘爪軸12上にナタ爪よりなる多数の耕耘爪13・13・・・が植設されて、該耕耘爪13の回転軌跡A上方が耕耘カバー20によって覆われ、両側はサイドカバー21によって覆われ、耕耘カバー20後端にはリアカバー22が連結されている。
【0009】
該リアカバー22は前板22aと後板22bがリンク22cによって連結されて、該前板22aと後板22bの間の下面にはゴム板30が固定されて、耕耘時に土の付着を防止して後方へ砕土された土が流れるようにしている。
そして、後板22bの後部には整地板31が枢支され、該整地板31の後部にはレーキ32が枢支されて、該レーキ32と整地板31の間にはダンパー33が介装されて、レーキ32を下方へ付勢し、整地板31とレーキ32によって均平に整地している。
【0010】
そして、前記耕耘爪軸12を駆動するための構成は、前記入力軸2よりギアボックス1内のベベルギア23・24からビーム3内の伝動軸25に伝えられて、チェーンケース10内の伝動軸25上のスプロケット26よりチェーン28を介してスプロケット27に伝えられて耕耘爪軸12が駆動され、耕耘爪13・13・・・が回転されることによって耕耘ができるようにしている。
【0011】
そして、前記ビーム3・3中途部より前方にプレート14・14・・・が固設されて、該プレート14・14・・・前端に支持杆15が横架され、該支持杆15に取付プレート16・16・・・が位置調節可能に外嵌して固定され、該取付プレート16に切断刃17の上部が高さ調節可能に固定されている。
なお、本実施例では切断刃17を左右対称に4本装着しているが、切断刃17の取付本数及び位置は限定するものではない。
但し、耕耘爪13と耕耘爪13の全ての間に切断刃17を設けることはなく、切断刃17を偏って配設することもない。そして、該切断刃17は上部を直線状に構成して、下部は後方に湾曲させて、側面視において切断刃17の下部が耕耘爪13の回転軌跡Aの前部でオーバーラップするように配置している。
【0012】
また、正面視において、切断刃17は所定の耕耘爪13と耕耘爪13の間に配置して、耕耘爪軸12を回転させた時に切断刃17と耕耘爪13が干渉しないように配置している。
本実施例では、図2、図5に示すように耕耘爪軸12の一列(一平面)に耕耘爪13が6本の場合には、両端の列とその内側の列との間と、その切断刃17から2列おいた内側に設けている。また、図6、図7に示すように、一列に耕耘爪13が4本の場合には、両端の列とその内側の列との間と、その切断刃17から3列おいた内側に設けている。
なお、両側から2番目と3番目の間に切断刃17を設けて2列又は3列おいて切断刃17を設けることもできる。
【0013】
この切断刃17は耕耘爪13と耕耘爪13の間に設けられることによって、耕耘作業時に、耕耘爪13と耕耘爪13の間の土塊を切断刃17で砕き、耕耘時の走行速度が上がるとロータリ耕耘装置が浮き上がり易くなるが、この切断刃17によって上昇を抑える。
そして、切断刃17の後面と耕耘カバー20の間に仕切板19が配設され、該仕切板19は切断刃17の背面に固設されて、仕切板19上部と耕耘カバー20内面(裏面)の間隔は極小さくして、仕切板19を耕耘カバー20に接近させて、藁や雑草等が入り込み絡み付かないようにしている。
【0014】
また、前記耕耘爪13の取付構成は、耕耘爪軸12に対して直角方向の同一平面に複数本(本実施例では、4本または6本)設けて、高速走行させた場合でも、ロータリの回転速度を上げなくてもよいロータリ耕耘装置を構成している。
つまり、耕耘爪軸12上の両端にはホルダー12a・12a・12aが一列に120°ごとに半径方向に突設されて、端用の耕耘爪13’が装着される。そして、この両端の列の間に、等間隔で複数列のホルダー12a・12b・・・が突設されて、それぞれ耕耘爪13・13・・・が取り付けられる。
【0015】
耕耘爪13はナタ爪よりなり、切り込んでから土を反転させるために先端部は右又は左に湾曲させており、この湾曲方向は左右交互に向くように、一列のホルダー12a・12b・・・に装着されている。
しかも、同列上の隣接するホルダー12aとホルダー12bは交互に配設されて、それぞれのホルダーの取付角度は等間隔となっていない。つまり、隣接するホルダー12aとホルダー12bの取付角度差は大小交互に設定されている。
そして、ホルダー12a・12b・・・は図3に示すように、列ごとに少しずつ取付角度が異なるようにして、位相差を設けており、ホルダーの中心線は側面視で一致しないように放射状に設定して、同時に耕耘爪13が圃場面に入り込むことを避けて、力の分散を図っている。
【0016】
そして、耕耘爪軸12上の湾曲させた互いに向かい合う耕耘爪13と耕耘爪13の先端の間隔は従来と違って広く開けており、両側と中央側の耕耘爪列の耕耘爪列の幅L1、L2の合計は、ロータリ耕耘装置の耕耘幅の70〜90パーセントで耕耘するようにしており、好ましくは80パーセント程度に設定しており、耕耘爪列と耕耘爪列の間の非作用部分は直接耕耘爪に切り込まれることはないが、反転する力はその部分にまで及ぶので、非耕耘部分が生じることはなく耕耘され、土塊は適宜配設した前記切断刃17で土塊を切断しながら耕耘される。
【0017】
また、耕耘爪列の幅方向の間隔は図2に示すように、等間隔に配設することができ、図4に示すように、切断刃17を配置する耕耘爪列と耕耘爪列の間隔L3は更に広くし、切断刃17を配置しない耕耘爪列と耕耘爪列の間隔L4はL3よりも狭く配設するように構成することもできる。
【0018】
【発明の効果】
本発明は以上のように構成したので、次のような効果を奏する。
即ち、耕耘爪列と耕耘爪列の間隔が広くなり、しかも耕耘爪の数が少なくなるので、耕耘抵抗が減少して、高速で耕耘することが可能となる。
そして、間隔の広い部分に切断刃が配置されるので、土塊は砕かれて砕土性を低下させることがなく、また、直接耕耘爪が当たらない部分であっても、耕耘爪の反転力が及び耕耘はされる。
【0019】
耕耘爪の数を減少できるので、ロータリ耕耘装置の軽量化が図れ、駆動力も小さくて済み、負荷に対する余裕ができて更に高速で耕耘することも可能となり、しかも、耕耘爪を減少できるので、枠体の強度も減少できてコスト低減化も図れる。

Plowing work by rotating the nail shaft.
As a configuration for fixing the tilling nail to the tilling nail shaft, on the outer periphery of the tilling nail shaft, a nail holder is projected in a spiral manner at a predetermined interval, and the tilling nail is bent in the right or left direction in the nail holder. In order to prevent the non-cultivation part from being installed, the width between the tilling claws is reduced as much as possible in the width direction. There was no area.
[0003]
[Problems to be solved by the invention]
In such a conventional rotary tiller, in order not to have a non-tillage portion, a number of tilling claws must be mounted on the tilling pawl shaft, which not only increases the weight but also Because there are many, tillage resistance when cutting into the soil also increased, and it was necessary to increase the driving force for rotating the rotary.
Also, if the traveling speed during tillage work is increased in order to finish the work quickly, the tillage pitch may become coarse and the clot may become too large.To prevent this, increasing the rotational speed of the rotary will increase the load. There was a limit to increasing the speed of tillage.
Therefore, the present invention aims to provide a tilling method that improves the mounting structure of the tilling claw of the rotary tilling device and can increase the traveling speed and perform a favorable tilling work even if the rotation speed of the tilling claw shaft remains the same. It is.

The cutting blade 17 has a straight upper portion and a lower portion bent backward. Thus, when viewed from the side, the lower part of the cutting blade 17 is arranged so as to overlap the front part of the rotation trajectory A of the tilling claw 13, the width L 1 of the tilling claw rows on both sides on the tilling claw shaft 12, and the middle side tilling The total of the width L2 of the nail row is 70 to 90% of the tillage width of the rotary tiller, and the non-acting portion of the tillage nail 13 between the tilling nail row is affected by the reversal force of the tilling nail 13. It is plowed and further plowed while cutting the clod with the cutting blade 17.
[0005]
[Action]
By using such means, the following operation is performed.
Even with rotary tillers with the same tillage width, the number of tilling claws attached is reduced, the weight is reduced, and the tiller claws directly act on the narrower width, and the tillage resistance becomes smaller and faster than before. You will be able to plow.
And the bending direction of the tilling nail is the same plane in the left and right direction, and even if it is the part of the soil that is not directly cut, the force when it is reversed by the tilling nail is transmitted and reversed, and the soil is tilled evenly Is done.
