A scraper 83 for removing swarf and the like accumulated on the upper surface of the cutting blade device 9 is provided on the lower surface side (the cutting blade device 9 side) of the rightmost large diameter star wheel 82b and the small diameter star wheel 82s. ing. A rubber plate 83a is attached to the lower part of the scraper 83 and is deformed by the unevenness of the upper surface of the cutting blade device 9, so that it also acts on a part such as a concave part where it is difficult to remove sawdust and can be effectively removed. .
Further, any of the scrapers 83 (small-diameter star wheel 82 s side in the illustrated example) is biased from the rotation center of the star wheel, so that the culm can be prevented from being caught between the scrapers 83.
(カバー体)
各穀稈引起装置8の上部は、左右横方向に長く構成されたカバー体15によって被覆される構造になっている。カバー体15は金属板により形成する他、ポリカーボネート等の樹脂により形成することも可能であり、その場合透明又は半透明にしてカバー体15越しの視認性を確保するのも好ましい。
(Cover body)
The upper part of each grain raising apparatus 8 has a structure covered with a cover body 15 that is long in the lateral direction. The cover body 15 can be formed of a metal plate or a resin such as polycarbonate. In this case, it is preferable that the cover body 15 is transparent or semi-transparent to ensure visibility through the cover body 15.
カバー体15は、穀稈引起装置8の引き起し経路Kに沿って上昇する引起しラグ14の上昇軌跡の上方延長線上に配置し、側面視において、前側引起しケース12の上部傾斜面12uの傾斜姿勢に沿う状態と、上昇移行する引起しラグ14における引起し経路Kの上方をカバーする状態とに、前後方向の傾斜姿勢を変更自在に構成されている。そして、このカバー体15の姿勢変更手段として、前後上下のスライド構成とすることもできるが、本実施例では図9〜図12に示されるように、左端及び右端の穀稈引起装置8の背部側に支持ステー8s,8sがそれぞれ立設されるとともに、これら支持ステー8s,8s間に左右横方向に延在するカバー体支軸16が架設され、カバー体15はこのカバー体支軸16を回動支点として上下に揺動開閉するよう揺動開閉自在に構成されている。カバー体15の上方への開側が引起し経路Kの上方をカバーする姿勢変更状態(開姿勢)であり、下方への閉側が前側引起しケース12の上部傾斜面12u前面をカバーする姿勢変更状態(閉姿勢)となる。カバー体15の開閉は、回動支点付近に設けた引張スプリング17により、カバー体支軸16の支点に対してスプリング張力方向を閉側と開側とに切り替え可能な構成になっていて、ワンタッチで揺動開閉することができる。   The cover body 15 is disposed on the upper extension line of the rising locus of the raising lug 14 that rises along the raising path K of the grain raising device 8, and in the side view, the upper inclined surface 12 u of the front raising case 12 is raised. The tilting posture in the front-rear direction can be freely changed to a state along the tilting posture and a state of covering the upper part of the raising path K in the raising lug 14 that moves up and down. And as an attitude | position change means of this cover body 15, although it can also be set as the slide structure of front and back, up and down, as shown in FIGS. 9-12 in a present Example, the back part of the grain raising apparatus 8 of a left end and a right end Support stays 8s and 8s are respectively provided on the side, and a cover body support shaft 16 extending in the left-right lateral direction is installed between the support stays 8s and 8s. As a rotation fulcrum, it is configured to swing open and close so as to swing up and down. The posture change state (open posture) in which the open side upward of the cover body 15 is raised and covers the upper side of the path K, and the posture change state in which the close side downward is raised forward to cover the front surface of the upper inclined surface 12u of the case 12 is performed. (Closed posture). The cover body 15 can be opened and closed by a tension spring 17 provided in the vicinity of the rotation fulcrum so that the spring tension direction can be switched between the closed side and the open side with respect to the fulcrum of the cover body support shaft 16. Can be swing open and closed.
分草後の穀稈は、穀稈引起装置8の引起しケース12,13から引起し経路K内に突出して上昇する引起しラグ14が株元側から穂先側にかけて作用することで引き起こされる際、引起し作用によって穀粒等が運転席5のオペレータに向かって飛散することがあるが、カバー体15を例えば穀粒等の飛散方向と交差する開姿勢に姿勢変更することにより、引起しラグ14により飛び散る穀粒等をカバー体15によって効果的に遮ることができる。   The cereals after weeding are caused by the raising lugs 14 that are raised from the raising cases 12 and 13 of the grain raising device 8 and project and rise in the path K from the plant side to the tip side. The grain or the like may be scattered toward the operator of the driver's seat 5 due to the pulling action, but the cover body 15 is raised to the lag by changing the posture to an open posture intersecting with the scattering direction of the grain or the like. The grains scattered by 14 can be effectively blocked by the cover body 15.
カバー体15は、平板状のもの等、適宜の形状とすることができるが、本実施形態のように、上面カバー部15aと後面カバー部15bとからなるように側面視で略への宇型に形成されていると、上面カバー部15aの下面部で穀粒等の上方への飛散を阻止し、後面カバー部15bの下面部で穀粒等の後方上方への飛散を阻止することができ、従って、運転席5への穀粒等の飛散を確実に防止することができるようになるため好ましい。   The cover body 15 can be formed in an appropriate shape such as a flat plate shape. However, as in the present embodiment, the cover body 15 is substantially U-shaped in a side view so as to be composed of an upper surface cover portion 15a and a rear surface cover portion 15b. If it is formed in the upper surface cover portion 15a, the lower surface portion of the upper surface cover portion 15a can prevent upward scattering of grains and the like, and the lower surface portion of the rear surface cover portion 15b can prevent scattering of grains and the like rearward and upward. Therefore, it is preferable because it is possible to reliably prevent the grains and the like from being scattered to the driver's seat 5.
カバー体15は、開状態において上面カバー部15aが引起しラグ14の上昇軌跡の上方延長線と交差する配置が好ましいが、後面カバー部15bが引起しラグ14の上昇軌跡の上方延長線と交差する配置とすることも可能である。また、カバー体15を引起しラグ14の上昇軌跡の上方延長線から後方側にずらし、後述する調節体50をそのカバー範囲の前方拡大により引起しラグ14の上昇軌跡の上方延長線上に位置させる構造とすることも可能である。   The cover body 15 is preferably arranged so that the upper surface cover portion 15a is raised and intersects with the upward extension line of the rising locus of the lug 14 in the open state, but the rear surface cover portion 15b is raised and intersects with the upper extension line of the rising locus of the lug 14 It is also possible to arrange them. Further, the cover body 15 is raised and shifted from the upper extension line of the rising locus of the lug 14 to the rear side, and the adjusting body 50 described later is raised by the front enlargement of the cover range to be positioned on the upper extension line of the raising locus of the lug 14. A structure is also possible.
本実施形態の多条刈りコンバインのように、左右方向中間の引起装置の左右両側に引起し経路をそれぞれ有する場合、当該引起装置の下部前方の分草体により隣接条の穀稈は分離されて左右の各引起し経路に導入される。しかし、穀稈が長稈の場合等においては、隣接条の穀稈の穂先が絡んで分離されずに当該引起装置を跨いでクロスしたまま刈刃装置9により刈り取られ、後方に搬送されることがある。この際、当該引起装置の上端とカバー体15とが接触していると、当該引起装置を跨ぐクロス部分がこの接触部分に引っ掛かり後方に通過できずに詰まってしまう。また、穀稈の搬送力により穂先の絡みが無理に解けたとしても、穂先相互のしごき作用又はカバー体15と引起しケース12,13との隅部によるしごき作用により穂先の穀粒が脱粒することは避け難い。よって、左右方向中間の穀稈引起装置8(中間引起装置8c)の左右両側に引起し経路をそれぞれ有する場合、少なくとも当該穀稈引起装置8の上端とカバー体15との間に穀稈通過空間15sが確保される構造とし、この穀稈通過空間15sにより左右両側の引起し経路を繋ぐことにより、穀稈の穂先部分がクロスしていてもそのまま後方に通過する構造とするのが好ましい。   Like the multi-row harvesting combine of the present embodiment, when each of the left and right sides of the pulling device in the middle in the left-right direction has a path to be raised, the grain of the adjacent row is separated by the weed body in front of the lower part of the pulling device. Introduced into each of the wake-up paths. However, in the case where the culm is a long culm, it is cut by the cutting blade device 9 while being crossed across the pulling device without being entangled and separated by the tip of the adjacent culm and transported backward. There is. At this time, if the upper end of the pulling device and the cover body 15 are in contact with each other, a cross portion straddling the pulling device is caught by the contact portion and cannot be passed rearward and is clogged. Moreover, even if the entanglement of the tip is forcibly solved by the conveying force of the cereal, the grain of the tip is shattered by the squeezing action between the tips or the squeezing action by the cover 15 and the corners of the cases 12 and 13. It is hard to avoid. Therefore, when it has a raising path on both the left and right sides of the grain raising apparatus 8 (intermediate raising apparatus 8c) in the middle in the left-right direction, the grain passing space is at least between the upper end of the grain raising apparatus 8 and the cover body 15. It is preferable to have a structure in which 15s is ensured, and by connecting the raised paths on the left and right sides by this culm passage space 15s, the structure passes through the rear as it is even if the tip part of the culm is crossed.
このような穀稈通過空間15sは、カバー体15の姿勢如何によらず形成される構造とすることも可能である。その場合、カバー体15の閉状態において、カバー体15と穀稈引起装置8の隙間を形成しつつも、カバー体15の下端と穀稈引起装置8の上端部とが正面視において重合するような配置とすることが望ましい。   Such a cereal pass space 15s may be formed so as to be formed regardless of the posture of the cover body 15. In that case, in the closed state of the cover body 15, the lower end of the cover body 15 and the upper end portion of the culm pulling device 8 are overlapped in a front view while forming a gap between the cover body 15 and the culm pulling device 8. Is desirable.
また、穀稈引起装置8の上部に左右方向で複数の穀稈引起装置8にわたる引起伝動軸を設け、この引起伝動軸から各穀稈引起装置8に向けて駆動軸を分岐させて駆動するような形態においては、カバー体15の支持ステー8sは、この引起伝動軸の上部に固定する。
これによりカバー体15の支持剛性を高めることができる。
In addition, a pulling transmission shaft that extends across the plurality of the grain raising devices 8 is provided in the left-right direction on the upper portion of the grain raising device 8, and the drive shaft is branched from the raising transmission shaft toward each of the grain raising devices 8 to be driven. In this embodiment, the support stay 8s of the cover body 15 is fixed to the upper part of the pulling transmission shaft.
Thereby, the support rigidity of the cover body 15 can be improved.
本実施例では、各穀稈引起し装置8の左右両サイドに配置された刈取サイドカバー18,18は、上部サイドカバー18aと下部サイドカバー18bとに分割され、上部サイドカバー18aは、下部サイドカバー18bに対して上側面及び外側面上に重合し、前記カバー体15と連結により一体化され、該カバー体15と共に上下に揺動開閉可能に構成されている。刈取サイドカバー18,18と上部サイドカバー18aとは単一のカバー部材として形成しても良い。これにより、上部サイドカバー18aをハンドル代わりにして、上部サイドカバー18aとともにカバー体15を揺動させることができため、専用のハンドルを設けなくてもカバー体15の姿勢変更操作を容易に行うことができるようになる。また、本実施例では、カバー体15及び上部サイドカバー18aを上方に回動させないと、前側引起しケース12及び下部サイドカバー18bの取り外しができなくなっているため、カバー体15及び上部サイドカバー18aは、その下方への閉動によって前側引起しケース12及び下部サイドカバー18bをロックするロック機構の役目を果たす構造になっている。よって、上部サイドカバー18aの下部に重合した下部サイドカバー18bの着脱が簡単に行え、刈取部のメンテナンスも容易である。   In this embodiment, the cutting side covers 18 and 18 arranged on the left and right sides of each grain raising device 8 are divided into an upper side cover 18a and a lower side cover 18b, and the upper side cover 18a is a lower side cover. The cover 18b is superposed on the upper side and the outer side, and is integrated with the cover body 15 by being connected to the cover 18b. The cutting side covers 18 and 18 and the upper side cover 18a may be formed as a single cover member. Thus, the upper side cover 18a can be used as a handle, and the cover body 15 can be swung together with the upper side cover 18a. Therefore, the posture change operation of the cover body 15 can be easily performed without providing a dedicated handle. Will be able to. In this embodiment, the cover body 15 and the upper side cover 18a cannot be removed unless the cover body 15 and the upper side cover 18a are rotated upward. Has a structure that functions as a lock mechanism that locks the case 12 and the lower side cover 18b by raising the front side by the downward movement thereof. Therefore, the lower side cover 18b superposed on the lower part of the upper side cover 18a can be easily attached and detached, and the maintenance of the cutting part is also easy.
(調節体)
カバー体15の前端部に支軸51によって回動自在に取付けられた調節体50は、回動させて前方に張出させることによってオペレータへの穀粒等の飛散を効果的に防止できる。特に、カバー体15を穀稈引起装置8の上部穀粒等の飛散方向と交差する開姿勢に姿勢変更した状態で、調節体50をさらに前方に張出させると、飛散防止効果が高まる。
そして、この調節体50は、カバー体15の背面側に格納することが可能であり、調節体50を格納した状態でカバー体15を閉状態とすれば、調節体50が穀稈に干渉することを防止できる。
また、調節体50は先端側に折部を形成しており、この折部によって調節体50の剛性を高めることができ、折部は下方に向けて折り曲げているので、藁屑の堆積を防止できる。
(Regulator)
The adjusting body 50 attached to the front end portion of the cover body 15 so as to be rotatable by the support shaft 51 can effectively prevent the grains and the like from being scattered to the operator by rotating and projecting forward. In particular, when the adjustment body 50 is further extended forward in a state in which the cover body 15 is changed to an open posture that intersects with the scattering direction of the upper grain of the cereal habit raising device 8, the scattering prevention effect is enhanced.
And this adjustment body 50 can be stored in the back surface side of the cover body 15, and if the cover body 15 is made into a closed state in the state which stored the adjustment body 50, the adjustment body 50 will interfere with a grain candy. Can be prevented.
Further, the adjusting body 50 is formed with a folded portion at the tip side, and the rigidity of the adjusting body 50 can be increased by the folded portion, and the folded portion is bent downward, so that accumulation of sawdust is prevented. it can.
(分草ガイド)
図16から図19には、穀稈が倒伏状態で絡みあうような圃場状態で効果的に引起しを行うために、中央2条分の穀稈引起装置8の間に分草ガイド74を設けた刈取装置4の要部を示す。図16及び図17に示す分草ガイド74は、中空又は中実の断面円形の棒状部材であり、分草フレーム73における穀稈引起装置8の前側部位、又は分草体7に下端部が連結されており、上部が穀稈引起装置8の上部に固定されている。
そして、分草ガイド74は、側面視において分草フレーム73に下部連結部74bで連結された下端部から穀稈引起装置8の前面との間隔が上方へ行くに従い増加する傾斜をもって上方へ向かい(下側分草部74v)、穀稈引起装置8の高さ方向における中央部に対応する位置で屈曲し(屈曲部74c)、前述した前側引起しケース12の上部傾斜面12uの傾斜面と略同一の傾斜角度で後上がり傾斜して(上側分草部74s)、この上部傾斜面12uの屈曲位置12c近傍において、後方に向けて屈曲させ、この分草ガイド74の上端部である取付部74uが、穀稈引起装置8の上部に取付られている。なお、上記の上側分草部74sの傾斜角度は、側面視において閉状態のカバー体15とも略同一の角度である。
このように、分草ガイド74の上側分草部74sの傾斜角度を引起しケース12の上部傾斜面12uと略同一の角度に設定し、上側分草部74sと上部傾斜面12uとを連続的な傾斜に形成することで、分草ガイド74と引起しケース12の前面の交差する点において引っ掛かる虞がなく、引起しラグ14の引起し作用によって起立してくる穀稈の穂先を引起し経路内にスムーズに取り込めるため、穂先の扱きによる脱粒や稈切れを抑制することができる。また、カバー体15を開状態としている場合、引起し経路を跨いでクロスした穀稈の穂先が分草ガイド74によって分草され、クロスした穂先が上部傾斜面12uにスムーズに案内され、穀稈引起装置8とカバー体15との間を通り抜けて後方に搬送することができる。
また、図18及び図19に示すのは、異なる形態の分草ガイドを備える刈取装置4である。
この分草ガイド75は、穀稈引起装置8の上端部よりも更に上方まで延伸されている点と、延伸した上端部でカバー体15の中間部を回動自在に支持している点で前述のものと相違する。
すなわち、分草ガイド75は、側面視において分草フレーム73に下部連結部75bで連結された下端部から穀稈引起装置8の前面との間隔が上方へ行くに従い増加する傾斜をもって上方へ向かい(下側分草部75v)、穀稈引起装置8の高さ方向における中央部に対応する位置で屈曲し(屈曲部75c)、前述した前側引起しケース12の上部傾斜面12uの傾斜面と略同一の傾斜角度で後上がり傾斜して(上側分草部75s)、穀稈引起装置8のよりも後側かつ上方に至り、上側分草部75sの上端部のカバー体支持部75seにてカバー体15のカバー体支軸16を回動自在に支持している。なお、上側分草部75sにおける穀稈引起装置8の上端部近傍の部位には取付部75uを設けており、この取付部75uで穀稈引起装置8に固定される。
このように、分草ガイド75の上側分草部75sを穀稈引起装置8の上方までにわたり設けたことで、稈長が非常に長く、穀稈引起装置8の上端部よりも高い位置まで穂先部を有する穀稈の分草において、引起し経路を跨いでクロスする穀稈を確実に左右に分草し、後方の搬送装置へ移送することができる。穀稈がクロスしたまま脱穀装置3へ搬送されると、脱穀負荷が増大し、作業効率が低下したり脱穀装置内からの騒音が増大する虞があるが、絡み合った穀稈を分離することでこの問題点を解消できる。また、上側分草部75sのカバー体支持部75seでカバー体15の中間部を支持する形態を採用することでカバー体15の剛性が高まり、穀稈引起装置8の上方を通過する穀稈がこのカバー体15に干渉しても変形しにくくなるという利点もある。
(Weeding guide)
In FIGS. 16 to 19, a weeding guide 74 is provided between the middle two stalk raising devices 8 in order to effectively raise the stalks in a field state where the cereals are entangled in a lying state. The principal part of the reaping device 4 is shown. The weed guide 74 shown in FIGS. 16 and 17 is a hollow or solid rod-shaped member having a circular cross section, and the lower end portion is connected to the front portion of the grain raising device 8 in the weed frame 73 or the weed body 7. The upper part is fixed to the upper part of the grain raising apparatus 8.
And the weed guide 74 heads upwards with an inclination which increases as the space | interval with the front surface of the grain raising apparatus 8 goes upwards from the lower end part connected with the weed frame 73 by the lower connection part 74b in side view ( The lower weed portion 74v) is bent at a position corresponding to the central portion in the height direction of the cereal haul raising device 8 (bending portion 74c), and is substantially the same as the inclined surface of the upper inclined surface 12u of the front raising case 12 described above. Inclined rearward at the same inclination angle (upper weed portion 74s), bent backward in the vicinity of the bending position 12c of the upper inclined surface 12u, and attached portion 74u which is the upper end portion of the weed guide 74 Is attached to the upper part of the grain raising apparatus 8. Note that the inclination angle of the upper weed portion 74s is substantially the same as that of the cover body 15 in the closed state in a side view.
In this way, the inclination angle of the upper weed portion 74s of the weed guide 74 is raised to be set to substantially the same angle as the upper inclined surface 12u of the case 12, and the upper weed portion 74s and the upper inclined surface 12u are continuously formed. By forming it with a gentle slope, there is no risk of catching at the point where the weed guide 74 and the front surface of the case 12 intersect, and the path of the cedar that stands by the raising action of the raising lug 14 is raised. Since it can be taken in smoothly, it is possible to suppress degranulation or cutting of the stem due to handling of the tip. Further, when the cover body 15 is in the open state, the tip of the culm that has been raised and crossed across the path is weeded by the weed guide 74, and the crossed tip is smoothly guided to the upper inclined surface 12u, It can pass between the pulling device 8 and the cover body 15 and be conveyed backward.
Moreover, what is shown in FIG.18 and FIG.19 is the cutting device 4 provided with the weed guide of a different form.
The weed guide 75 is described above in that it is extended further upward than the upper end of the grain raising device 8 and the intermediate part of the cover body 15 is rotatably supported by the extended upper end. It is different from the one.
That is, the weed guide 75 moves upward with an inclination that increases as the distance from the lower end connected to the weed frame 73 by the lower connecting portion 75b to the front surface of the grain raising device 8 increases in a side view ( The lower weed portion 75v) is bent at a position corresponding to the center portion in the height direction of the cereal habit raising device 8 (bending portion 75c), and substantially the same as the inclined surface of the upper inclined surface 12u of the front raising case 12 described above. Inclined rearward at the same inclination angle (upper weed portion 75s), reaches the rear side and the upper side of the grain raising device 8, and is covered with the cover body support portion 75se at the upper end portion of the upper weed portion 75s. The cover body support shaft 16 of the body 15 is rotatably supported. In addition, the attachment part 75u is provided in the site | part of the upper weed part 75s in the vicinity of the upper end part of the cereal habit raising device 8, and it is fixed to the cereal habit raising device 8 by this attachment part 75u.
Thus, by providing the upper weeding part 75 s of the weeding guide 75 to the upper part of the grain raising apparatus 8, the tip length is very long and the tip part is higher than the upper end part of the grain raising apparatus 8. In the cereal weeds, the cedar that is raised and crossed across the path can be reliably weeded to the left and right and transferred to the rear conveying device. If the cereals are transported to the threshing device 3 while being crossed, there is a risk that the threshing load will increase, the work efficiency will decrease, or the noise from the threshing device will increase, but by separating the entangled cereals This problem can be solved. Moreover, the rigidity of the cover body 15 is increased by adopting a form in which the cover body support portion 75se of the upper weed portion 75s supports the intermediate portion of the cover body 15, and the cereal rice cake that passes above the cereal wakening device 8 is increased. There is also an advantage that even if it interferes with the cover body 15, it is difficult to deform.
(補助引起装置)
図14から図15には、穀稈が倒伏状態で絡みあうような圃場状態で効果的に引起しを行うために、穀稈引起装置8の前方位置に補助引起装置60を設けた刈取装置4の要部を示している。この補助引起装置60は、補助引起しラグ62を前方に突出させながら倒伏状態で絡みあう穀稈に対して左右に分割しながら引起し回動するものであり、補助引起しケース61と、この補助引起しケース61に内装された、駆動スプロケット64B及び張設輪65に巻回されて駆動される無端の補助引起チェン66と、この補助引起チェン66に所定の間隔で取り付けられた補助引起しラグ62とを有している。
そして、補助引起装置60は、上下中間部位を駆動ケース63によって穀稈引起装置8と連結され、下部は分草フレーム73に連結されて固定されている。
この駆動ケース63には図示せぬ穀稈引起装置8を駆動する引起駆動軸70と一体回転する伝達軸を備えており、この伝達軸の補助引起装置60側端部のベベルギアと、機体左右方向に沿う中間軸63Aのベベルギア63Bとが噛合わされている。中間軸63Aのベベルギア63Bとは反対側の端部には中間スプロケット63Cを有する。なお、中間スプロケット63Cは、補助引起しケース61における駆動ケース63とは反対側に膨出した膨出部61Aの内側に臨んでいる。そして中間スプロケット63Cと、補助引起装置60の上部に位置する従動スプロケット64Aとに掛け回されたチェンによって、中間軸63Aに入力された駆動力を、前述の駆動スプロケット64Bを有するデバイダ駆動軸64へ伝達する。なお、補助引起装置60の下部の張設輪65は、常時補助引起しチェン66に張力を与えるように、下方に向けて付勢されている。
そして、補助引起装置60の補助引起チェン66の移動速度は、穀稈引起装置8の引起しチェンの移動速度よりも高速に設定している。
このように、補助引起装置60は穀稈引起装置8の引起駆動軸70よりも上方であって引起装置8の上端部よりも上方に配置した駆動スプロケット64Bに補助引起しチェン66が巻き掛けられており、これに取り付けられた補助引起しラグ62も駆動スプロケット64Bの高さまで上昇しながら分草する。従って、従来の補助引起装置は、補助引起しラグの作用域の上端部が穀稈引起装置の駆動スプロケットと略同等の高さであったために、稈長の長い穀稈の分草性が低く、穂先が絡まったまま後方に搬送されて脱穀装置の処理効率が低下する問題があったが、上記構成によって分草性能が向上し、長稈の倒伏圃場等、穀稈の分草が困難な場合でも確実に分草することができ、穀稈引起装置や搬送装置における詰まりを防止し、脱穀効率を向上させることができる。
また、補助引起装置60の補助引起チェン66の移動速度は、穀稈引起装置8の引起しチェンの移動速度よりも高速に設定しているため、倒伏した穀稈を効率的に引起すことができる。
(Auxiliary pulling device)
In FIGS. 14 to 15, the reaping device 4 is provided with an auxiliary pulling device 60 at a position in front of the culm pulling device 8 in order to effectively lift the culm in a field state where the culm is entangled in a lying state. The main part is shown. The auxiliary pulling device 60 is a device that pulls up and rotates while dividing the left and right with respect to the cereals that are entangled in a lying state with the auxiliary pulling lug 62 protruding forward. An endless auxiliary pulling chain 66 wound around and driven by a drive sprocket 64B and a tensioning wheel 65, and an auxiliary pulling trigger attached to the auxiliary pulling chain 66 at a predetermined interval. And a lug 62.
The auxiliary pulling device 60 is connected to the grain raising device 8 at the upper and lower intermediate portions by the drive case 63, and the lower portion is connected to the weeding frame 73 and fixed.
The drive case 63 is provided with a transmission shaft that rotates integrally with a pulling drive shaft 70 that drives the grain raising device 8 (not shown), a bevel gear at the end of the transmission shaft on the side of the auxiliary pulling device 60, and the left-right direction of the body. Is engaged with the bevel gear 63B of the intermediate shaft 63A. An intermediate sprocket 63C is provided at the end of the intermediate shaft 63A opposite to the bevel gear 63B. The intermediate sprocket 63C faces the inner side of the bulging portion 61A that bulges to the side opposite to the drive case 63 in the auxiliary raising case 61. The driving force input to the intermediate shaft 63A is transferred to the divider drive shaft 64 having the drive sprocket 64B by the chain hung around the intermediate sprocket 63C and the driven sprocket 64A located above the auxiliary pulling device 60. introduce. Note that the tensioning wheel 65 at the lower part of the auxiliary pulling device 60 is urged downward so that the auxiliary pulling is always caused and tension is applied to the chain 66.
The moving speed of the auxiliary pulling chain 66 of the auxiliary pulling apparatus 60 is set higher than the moving speed of the pulling chain of the grain raising apparatus 8.
In this way, the auxiliary pulling device 60 has the auxiliary pulling chain 66 wound around the drive sprocket 64B arranged above the pulling drive shaft 70 of the grain pulling device 8 and above the upper end of the pulling device 8. The auxiliary pull-up lug 62 attached thereto also weeds while rising to the height of the drive sprocket 64B. Therefore, in the conventional auxiliary pulling device, the upper end portion of the working range of the auxiliary pulling lug was substantially the same height as the drive sprocket of the wheat straw pulling device, so that the herbicidal properties of the long wheat straw are low, When there is a problem that the processing efficiency of the threshing device is lowered while the tip is tangled, the weeding performance is improved by the above configuration, and it is difficult to weed cereals such as long-clad lodging However, it is possible to reliably weed, prevent clogging in the grain raising apparatus and the conveying apparatus, and improve the threshing efficiency.
Moreover, since the moving speed of the auxiliary pulling chain 66 of the auxiliary pulling device 60 is set to be higher than the moving speed of the pulling chain of the grain raising apparatus 8, it is possible to efficiently raise the fallen grain straw. it can.
