Description
【0001】[0001]
本考案は、伝動ケースをロータリカバーの片側に配設したサイドドライブロー タリ方式のロータリ耕耘装置に関するものである。 The present invention relates to a side-drive rotary type rotary tiller having a transmission case disposed on one side of a rotary cover.
【0002】[0002]
ロータリ耕耘装置は、爪軸を駆動する伝動ケースの取付位置の相違により、伝 動ケースを爪軸の長手方向中間部に取付けたセンタードライブ方式と、伝動ケー スをロータリカバーの片側に取付けて爪軸の動力を爪軸の一端側から導入するよ うにしたサイドドライブ方式(サイドドライブロータリ)に大別されるが、サイ ドドライブ方式のものは耕耘幅内に伝動ケースが存在せず畝がきれいに仕上る等 の利点があるため多く採用されている。 Depending on the mounting position of the transmission case that drives the pawl shaft, the rotary cultivator has a center drive system in which the transmission case is attached to the middle of the pawl shaft in the longitudinal direction, and a pawl shaft is mounted on one side of the rotary cover. It is roughly divided into a side drive system (side drive rotary) in which the power of the shaft is introduced from one end side of the pawl shaft, but the side drive system does not have a transmission case within the plowing width and the ridges are clean. It is often used because of its advantages such as finishing.
【0003】[0003]
しかし、サイドドライブロータリは、一般に図7に示すように、伝動ケース( イ)がロータリカバー(メインカバー)(ロ)よりも外側方に張出した状態で取 付けられているため、次のような欠点がある。すなわち、耕耘時、伝動ケース( イ)の横幅部分が未耕地として残ること、耕耘後、伝動ケース(イ)の通過跡に 凹部(図5におけるa)ができ、畝(ハ)がきれいな均平状に仕上らないこと、 深耕作業時に伝動ケース(イ)の下部が未耕地の土に押されて土圧抵抗が増大す るため馬力損失が大きくなること等である。 However, as shown in FIG. 7, the side drive rotary is generally mounted in a state in which the transmission case (a) is extended to the outside of the rotary cover (main cover) (b). There are drawbacks. In other words, during plowing, the width of the transmission case (a) remains as uncultivated land, and after plowing, a recess (a in Fig. 5) is created in the passage mark of the transmission case (a), and the ridge (c) is flat and even. It is not finished in a uniform shape, and during deep tillage work, the lower part of the transmission case (a) is pushed by the soil in the uncultivated land, increasing the earth pressure resistance and increasing horsepower loss.
【0004】[0004]
本考案は、上記のような実状に基づきなされたものであって、伝動ケースをロ ータリカバーの片側に配設したサイドドライブロータリにおいて、前記伝動ケー スをロータリカバーの幅内に設け、該伝動ケースの前面に伝動ケースの略全幅に わたるスキ幅を有するスキを固着し、該スキの最下端部を耕耘爪の回転軌跡最下 点と略同一高さでかつ耕耘爪の回転中心寄りに設定すると共に、伝動ケースの後 面側をケース内側面側からメインカバーの後部外側端近傍にかけて緩やかに傾斜 又は湾曲するガイド板で覆ったことを要旨とする。 The present invention has been made based on the above situation, and in a side drive rotary in which the transmission case is arranged on one side of the rotary cover, the transmission case is provided within the width of the rotary cover. A ski having a clearance width that extends over almost the entire width of the transmission case is fixed to the front surface of the power transmission case, and the lowermost end of the ski is set to be approximately the same height as the lowest locus of the rotation path of the tilling pawl and near the center of rotation of the tilling pawl. At the same time, the gist is that the rear surface side of the transmission case is covered with a guide plate that gently inclines or curves from the inner surface side of the case to the vicinity of the rear outer end of the main cover.

スキにより削り取られて伝動ケースの内側に移動させられた土は耕耘爪により 砕土され、外向きの耕耘爪により後方外側方へ跳飛ばされると共に、ガイド板で スムーズに外側へ移動し伝動ケースの通過跡(凹部)に埋め戻されるので耕耘後 に伝動ケースの通過跡が残ることがない。また、スキと耕耘爪両者の耕耘深さを 浅耕、深耕いずれの場合も略同一高さに保持されるので耕盤を傷めたり徒に馬力 を消耗したりすることがなく、耕耘後は均平できれいな仕上がりが得られる。 The soil scraped off by skid and moved to the inside of the transmission case is crushed by the plowing claws, and is then jumped rearward and outward by the outward plowing claws, and is smoothly moved to the outside by the guide plate to pass the transmission case. Since it is backfilled in the trace (recess), there is no trace of passage of the transmission case after plowing. In addition, since the depth of tillage of both the ski and the tiller is maintained at approximately the same height in both shallow and deep tillage, the tiller is not damaged and horsepower is not consumed to the person, and after tilling, it is even. A flat and beautiful finish is obtained.

本考案の構成を図面に示された一実施例により説明すれば、トラクタ(本機) 1の後方にロワリンク2、トップリンクブラケット3及びトップリンク4を介し て装着したヒッチフレーム5にサイドドライブ式のロータリ6が着脱自在に連結 されている。ロータリ6は本機1のPTO軸7から自在継手軸(図示せず)を介 して動力が伝達される中央のギヤケース8より両サイドに延設したパイプフレー ム9,10には進行方向左側に伝動ケース11が、右側にサイドプレート12が 夫々固定されている。そして、伝動ケース11の下部とサイドプレート12間に は耕耘爪13,13aを取付けた爪軸14が回転自在に装着されている。15は 円弧状のメインカバーで、その後端にはメインカバー15と同幅のリヤカバー1 6が支点ピン16aを介して上下回動自在に軸支されており、メインカバー15 とリヤカバー16によりロータリカバー17が形成されている。 The structure of the present invention will be described with reference to an embodiment shown in the drawings. A side-drive type hitch frame 5 is mounted behind a tractor (this machine) 1 via a lower link 2, a top link bracket 3 and a top link 4. The rotary 6 is detachably connected. The rotary 6 is on the left side in the traveling direction of the pipe frames 9 and 10 extending on both sides from a central gear case 8 to which power is transmitted from the PTO shaft 7 of the machine 1 through a universal joint shaft (not shown). The transmission case 11 and the side plate 12 are fixed to the right side and the right side, respectively. Then, between the lower part of the transmission case 11 and the side plate 12, a claw shaft 14 having cultivating claws 13 and 13a attached is rotatably mounted. Reference numeral 15 denotes an arc-shaped main cover, and a rear cover 16 having the same width as the main cover 15 is pivotally supported at its rear end through a fulcrum pin 16a so as to be vertically rotatable. The main cover 15 and the rear cover 16 serve as a rotary cover. 17 is formed.
【0007】 ところで、前記伝動ケース11はロータリカバー17の幅内に食込ませた状態 で配設されている。即ち、伝動ケース11は図2及び図3に示すようにメインカ バー15の幅内に設けられており、該伝動ケース11の前面11aには伝動ケー ス11の略全幅にわたるスキ幅を有するスキ18がブラケット19及び取付ボル ト20を介し直付けの方法で固着されている。スキ18を元々堅牢に形成されて いる伝動ケース11の前面11aを利用して取付けてあるためスキ18の取付部 は小スペースでしかも簡単な取付構造で済むものでありながら頑丈な取付構造と なっている。一方、上記スキ18の後部側に位置する最下端部Pは耕耘爪13, 13aの回転軌跡最下点Qと略同一高さでかつ耕耘爪13,13aの回転中心( 爪軸14の軸芯)寄りに設定されている(図1及び図4参照)。そして、伝動ケ ース11の後面11b側はケース内側面11c側からメインカバー15の後部外 側端近傍にかけて緩やかに傾斜又は湾曲するガイド板21で覆われている。この ガイド板21はメインカバー15の下面からメインカバー15とリヤカバー16 の枢結部下方の適宜高さまで延設された状態で伝動ケース11に一体的に固定さ れている。22はサイドカバーである。図中、符号23はトランスミッションケ ース、24は油圧ケース、25は油圧リフトアーム、26はツールバー、27は 耕耘土塊である。By the way, the transmission case 11 is arranged in a state of being bitten into the width of the rotary cover 17. That is, the transmission case 11 is provided within the width of the main cover 15 as shown in FIGS. 2 and 3, and the front surface 11a of the transmission case 11 has a ski 18 having a ski width that extends over substantially the entire width of the transmission case 11. Are fixed by a direct attachment method via a bracket 19 and a mounting bolt 20. Since the ski 18 is mounted using the front surface 11a of the transmission case 11 which is originally formed to be robust, the mounting portion of the ski 18 requires a small space and a simple mounting structure, but has a sturdy mounting structure. ing. On the other hand, the lowermost end P located on the rear side of the ski 18 has substantially the same height as the lowest locus Q of the rotation loci of the plowing pawls 13 and 13a, and the rotation center of the plowing pawls 13 and 13a (the axis of the pawl shaft 14). ) It is set closer (see FIGS. 1 and 4). The rear surface 11b side of the transmission case 11 is covered with a guide plate 21 that gently inclines or curves from the case inner surface 11c side to the vicinity of the rear outer end of the main cover 15. The guide plate 21 is integrally fixed to the transmission case 11 in a state of being extended from the lower surface of the main cover 15 to an appropriate height below the pivotal connecting portion of the main cover 15 and the rear cover 16. 22 is a side cover. In the figure, reference numeral 23 is a transmission case, 24 is a hydraulic case, 25 is a hydraulic lift arm, 26 is a toolbar, and 27 is a cultivated soil mass.
【0008】 さて、標準的な深さ或は深めの耕耘作業時には、図4に示すようにスキ18の 先端部は耕耘爪13,13aの回転軌跡最下点Qよりも若干高い位置にあるが、 スキ18の後部(最下端部P)は耕耘爪回転軌跡最下点Qと略同一高さにあるた め、スキ18と耕耘爪13,13aの耕耘深さは略同一となる。このスキ18と 耕耘爪13,13aの相対高さは図1に示すような浅耕時においても前記同様に 保たれる。したがって、スキ18と耕耘爪13,13a両者の耕耘深さが浅耕、 深耕いずれの場合も略同一深さに保持されるので、ロータリ6の耕耘姿勢が変わ っても耕盤(図6におけるD)を傷めたり馬力を徒に消耗したりすることがなく 均一できれいな畝Eの仕上がりを得ることができる。また、スキ18により削り 取られた土はスキ18の傾斜面18aに沿って伝動ケース11の内側に移動させ られた後、耕耘爪13,13aにより砕土され、外向きの耕耘爪13aにより後 方外側方へ跳飛ばされると共に、ガイド板21でスムーズに外側へ誘導され伝動 ケース11の通過跡(凹部)に埋め戻されるので従来のロータリのように伝動ケ ース11の通過跡(図5におけるa)が残ることがない。また、伝動ケース11 特にケース後面11b側への土の付着がなくなり作業終了後の土落し等の掃除が 容易となる。なお、ロータリ6をヒッチフレーム5から取外したとき、スキ18 がスタンドの代りになりロータリ6が前後に倒れるのが防止される。By the way, at the time of standard or deep plowing work, the tip of the ski 18 is at a position slightly higher than the lowest point Q of the rotation loci of the plowing pawls 13 and 13a as shown in FIG. Since the rear part of the ski 18 (the lowermost end P) is substantially at the same height as the lowest point Q of the plowing claw rotation locus, the plowing depth of the ski 18 and the plowing claws 13 and 13a are substantially the same. The relative height between the ski 18 and the tilling claws 13 and 13a is maintained in the same manner as above even during shallow tillage as shown in FIG. Therefore, the tilling depths of both the ski 18 and the tilling claws 13 and 13a are maintained at substantially the same depth both in the case of shallow tillage and in the case of deep tilling, so that even if the tilling posture of the rotary 6 changes, the tiller (see FIG. 6). It is possible to obtain a uniform and beautiful ridge E finish without damaging D) or exhausting horsepower. Further, the soil scraped off by the ski 18 is moved to the inside of the transmission case 11 along the inclined surface 18a of the ski 18, then is crushed by the plowing claws 13 and 13a, and is rearward by the outward plowing claw 13a. While being jumped outward, it is smoothly guided to the outside by the guide plate 21 and backfilled in the passage mark (recess) of the transmission case 11, so that the passage mark of the transmission case 11 (see FIG. 5) is the same as in the conventional rotary. a) does not remain. Further, since the adhesion of the soil to the transmission case 11 especially on the rear surface 11b side of the case is eliminated, it is easy to clean up the soil after the work is finished. When the rotary 6 is removed from the hitch frame 5, the ski 18 serves as a stand and prevents the rotary 6 from falling forward and backward.

本考案は、上記のように構成されているので、耕耘時に伝動ケース部分の未耕 地がなくなるうえ、伝動ケースの通過跡も均平に埋戻すことができ、また、スキ と耕耘爪両者の耕耘深さを浅耕、深耕いずれの場合も略同一高さに保持できるの で耕盤を傷めたりすることがなく、しかも、ガイド板により外向き爪からの耕耘 土塊を外側方へスムーズに移動させることができるので均平できれいな仕上がり を得ることができると共に馬力の消耗も少なく、また、伝動ケース等がロータリ カバーの外側方に突出せずデザイン的にも優れ商品価値を一層高めることが可能 となった。 Since the present invention is configured as described above, the cultivated area of the transmission case is eliminated when cultivating, and the traces of passage of the transmission case can be backfilled evenly. Both the shallow and deep tillage depths can be maintained at approximately the same height without damaging the tiller, and the guide plate smoothly moves the tilled soil mass from the outward facing claws to the outside. Since it is possible to obtain a flat and clean finish, there is little consumption of horsepower, and the transmission case etc. does not project to the outside of the rotary cover, it is also excellent in design and it is possible to further increase the commercial value.
