（刈刃装置）
次に、刈取部３の刈刃装置について説明する。
刈刃装置３１は、刈取部３の側面図およびそのＡ矢視図を図４、図５にそれぞれ示すように、刈取部３の刈取伝動ケース３２の前側に近接して左右全幅に及ぶ固定刃３３ａと、この固定刃３３ａに接して左右に往復動作可能に支持した可動刃３３ｂとから構成され、この可動刃３３ｂには左右駆動用のスライド溝３４ａを形成したＵ型受部３４を取付プレート３４ｂによって一体に固定する。 (Mowing blade device)
Next, the cutting blade device of the cutting unit 3 will be described.
As shown in FIGS. 4 and 5, the cutting blade device 31 is close to the front side of the cutting transmission case 32 of the cutting unit 3 and extends across the entire width as shown in FIGS. 4 and 5. 33a and a movable blade 33b supported so as to be capable of reciprocating left and right in contact with the fixed blade 33a. The movable blade 33b is provided with a U-shaped receiving portion 34 having a slide groove 34a for driving left and right. 34b is fixed integrally.

Ｕ型受部３４は、図５の要部拡大図を図６に示すように、可動刃３３ｂの往復動作方向と直交する上下の方向に延びる備え、このＵ型受部３４のスライド溝３４ａに内接するスライド面３５ａを両側に形成してスライド動作可能にポリウレタン樹脂等の耐摩材によるスライド部材３５を設け、このスライド部材３５にボールベアリング等の軸受３６を埋め込んでクランクアーム３７の半径Ｒの位置に形成した偏心ピン３７ａを軸支して刈刃駆動部を構成する。 As shown in FIG. 6, an enlarged view of the main part of FIG. 5 includes a U-shaped receiving part 34 that extends in a vertical direction perpendicular to the reciprocating direction of the movable blade 33 b, and a U-shaped receiving part 34 has a slide groove 34 a. An inscribed slide surface 35a is formed on both sides, and a slide member 35 made of a wear-resistant material such as polyurethane resin is provided so as to be slidable. A bearing 36 such as a ball bearing is embedded in the slide member 35, and a position of a radius R of the crank arm 37 is provided. A cutting blade drive unit is configured by pivotally supporting the eccentric pin 37a formed in the above.

上記構成の刈刃駆動部は、図７の動作説明図（ａ〜ｃ）に示すように、クランクアーム３７の回転動作により偏心ピン３７ａが半径Ｒの公転動作をすると、スライド部材３５を介してＵ型受部３４と一体の可動刃３３ｂが左右方向に±Ｒの範囲で往復駆動され、固定刃３３ａと可動刃３３ｂとにより刈取り穀稈を切断する。 As shown in the operation explanatory diagrams (a to c) of FIG. 7, when the eccentric pin 37 a revolves with the radius R by the rotation operation of the crank arm 37, the cutting blade driving unit configured as described above is interposed via the slide member 35. The movable blade 33b integrated with the U-shaped receiving portion 34 is driven to reciprocate in the range of ± R in the left-right direction, and the harvested cereal culm is cut by the fixed blade 33a and the movable blade 33b.

この時、スライド部材３５は、その片側のスライド面３５ａをＵ型受部３４のスライド溝３４ａに内接して切断駆動力を作用することから、その接触圧力が接触面に一様に平均化されて小さく抑えられることから、従来の円形部材の部分接触による大きな接触圧力とそれに伴う摩擦力増加を回避することができる。したがって、上記構成によって刈刃装置の耐久性、防振、防音性の向上とともに、衝撃破損を防止しつつ高速化による刈取作業の高速化が可能となることから、コンバインの作業能率の向上が可能となる。 At this time, since the slide member 35 is inscribed in the slide groove 34a of the U-shaped receiving portion 34 with the slide surface 35a on one side thereof being inscribed, the contact pressure is uniformly averaged on the contact surface. Therefore, it is possible to avoid a large contact pressure and a corresponding increase in frictional force due to partial contact of the conventional circular member. Therefore, with the above configuration, the cutting blade device can be improved in durability, vibration and soundproofing, and the cutting work can be speeded up at a high speed while preventing impact damage, so the work efficiency of the combine can be improved. It becomes.

また、上記構成の刈刃駆動部について、図８の拡大側面図に示すように、スライド部材３５がその上昇限度位置においてＵ型受部３４の上端から所定高さＢまで突出するように構成することにより、スライド部材３５が下降したときにＵ型受部３４のスライド溝３４ａに入り込んだ泥やゴミ等の異物が上端から外に押し出され、スライド面が清浄に保たれることから、スライド面に異物が介在することによる摩耗を防止することができる。 Further, the cutting blade driving unit having the above-described configuration is configured such that the slide member 35 protrudes from the upper end of the U-shaped receiving unit 34 to a predetermined height B at the upper limit position as shown in the enlarged side view of FIG. Thus, when the slide member 35 is lowered, foreign matters such as mud and dust that have entered the slide groove 34a of the U-shaped receiving portion 34 are pushed out from the upper end, and the slide surface is kept clean. It is possible to prevent wear due to the presence of foreign matter on the surface.

また、別の構成によるスライド部材を図９の拡大側面図に示すように、スライド部材３５の長さと幅を共通の寸法として左右と上下の４面をスライド面３５ａとすることにより、縦横の区別なしに容易に組付けすることができ、面圧も高くできるので、高耐久化が可能となる。さらに、摩耗状態を確認できるように升目状の摩耗限度線３５ｂを設け、摩耗時に９０°回転して再組付けすることによって耐久性延長が可能となる。 Further, as shown in the enlarged side view of FIG. 9, the slide member having another configuration has the same length and width as the slide member 35, and the left and right and upper and lower four surfaces are set as slide surfaces 35 a, thereby distinguishing the vertical and horizontal directions. Since it can be assembled easily and the surface pressure can be increased, high durability can be achieved. Further, a grid-like wear limit line 35b is provided so that the wear state can be confirmed, and the durability can be extended by rotating 90 ° and reassembling at the time of wear.

（刈取接地部材）
図１０の刈取部の側面図に示すように、刈取部３の下端部の丸パイプによる前フレーム４１にソリ状の接地部材４２を設け、この接地部材４２を圃場面に接地して刈取部３を所定の高さ位置に支持可能に構成する。接地部材４２は、図１１の拡大横断面図に示すように、その一方の側端部からＬ型に立上がる取付部材４３を設けて上下に延びる長穴を形成し前フレームの片側位置にボルトＢで固定することにより、下位取付け状態（ａ）から上位取付け状態（ｂ）まで高さ調節可能に構成する。 (Cutting ground member)
As shown in the side view of the cutting part in FIG. 10, a sledge-shaped grounding member 42 is provided on the front frame 41 made of a round pipe at the lower end of the cutting part 3, and this grounding member 42 is grounded to the field scene and the cutting part 3 is grounded. Is configured to be supported at a predetermined height position. As shown in the enlarged cross-sectional view of FIG. 11, the grounding member 42 is provided with a mounting member 43 that rises in an L shape from one side end portion thereof to form a long hole extending vertically, and a bolt at one position of the front frame. By fixing with B, the height can be adjusted from the lower mounting state (a) to the upper mounting state (b).

上記構成の接地部材４２により、通常の収穫走行時は、接地部材４２を下位取付けによって引起ラグ４４の下端を分草フレーム４１より隙間を空けて上部に設定して刈取部３を圃場面より高い一定位置に保持し、一方、完全倒伏の穀稈の収穫時は、接地部材４２を上位取付けとし、引起ラグ４４が倒伏杆に掛かる位置まで前フレーム４１が圃場に沈むように刈取部３を低く保持する。 With the grounding member 42 having the above configuration, during normal harvesting traveling, the grounding member 42 is attached at a lower position so that the lower end of the raising lug 44 is set at the upper part with a gap from the weeding frame 41 so that the cutting unit 3 is higher than the field scene. At the same time, when harvesting fully lying cereals, the grounding member 42 is mounted on the upper side, and the cutting part 3 is kept low so that the front frame 41 sinks into the field until the pulling lug 44 is placed on the lying sledge. To do.

従来の接地部材は、分草フレーム４１の下で高さ調節可能に構成されていたことから、分草フレーム４１を圃場面まで下げることができず、完全倒伏穀稈の収穫に対応できなかったが、上記のように接地部材を分草フレーム４１の片側位置で分草フレームより高く固定できるように調節代を設けることにより、下位取付けにより刈取部３を圃場面より高くフローティング保持して一定高さで収穫走行することができ、また、上位取付けにより前フレーム４１が圃場面に沈むように刈取部３を低く保持することにより、完全倒伏の穀稈を引起しつつ収穫走行することができる。 Since the conventional grounding member was configured to be adjustable in height under the weed frame 41, the weed frame 41 could not be lowered to the field scene, and could not cope with the harvesting of a completely lying cereal meal. However, by providing an adjustment allowance so that the grounding member can be fixed higher than the weeding frame at one side of the weeding frame 41 as described above, the mowing unit 3 is floated higher than the field scene by a lower attachment and is kept at a constant height. The harvesting can be carried out, and by holding the cutting unit 3 low so that the front frame 41 sinks into the field scene by the upper attachment, the harvesting running can be carried out while causing a completely lying cereal.

（スクレーパ）
次に、刈取部のスクレーパとしてのショベルについて説明する。
刈取部３には、その側面図と正面図を図１２および図１３に示すように、落下泥土清掃のために、路上についた泥やワラ屑を剥ぎ取るスクレーパとして、外付け型のスクレーパショベル５１を設ける。 (Scraper)
Next, an excavator as a scraper of the cutting unit will be described.
As shown in FIGS. 12 and 13, a side view and a front view of the mowing unit 3 include an external scraper excavator 51 as a scraper for stripping off mud and straw scraps on the road for cleaning the falling mud. Is provided.

ショベル５１は、図１４の分解斜視図に示すように、半円状のスクレーパ部５２の両側にアーム５３，５３を設け、刈取部３の前面部に左右の分草杆に横方向にまたがって刈刃装置の可動刃３３ｂと連結して左右動作可能に構成する。ショベル高さはラグ作用高さとし、ラグ作用をカバーして泥の巻き込みを防止するように外部接続することにより、ショベルと刈刃を連結連動させて道路にへばりついた泥を分離させつつ、ショベルで道路に落ちた泥を集めたり、圃場に落とし込んで清掃することができる。 As shown in the exploded perspective view of FIG. 14, the excavator 51 is provided with arms 53, 53 on both sides of a semicircular scraper portion 52, and horizontally across the right and left weed ridges on the front portion of the cutting portion 3. It is connected to the movable blade 33b of the cutting blade device so as to be movable left and right. The excavator height is the lag action height, and by connecting externally so as to cover the lag action and prevent the mud from getting caught, the excavator and the cutting blade are linked and linked to separate the mud stuck to the road, You can collect mud that has fallen on the road, or drop it into the field and clean it.

上記ショベル５１は、上記構成に限ることなく、必要により、左右の分草杆先端と前フレーム側面に設置し、固定するように構成してもよく、また、ラグ作用高さより高く固定してラグ作用を用いることにより泥の差込を防止することができる。 The excavator 51 is not limited to the above-described configuration, and may be configured to be installed and fixed on the left and right tip of the left and right side of the front frame and the side of the front frame, if necessary. By using the action, mud insertion can be prevented.
