Description

本発明は、コンバインに関する。   The present invention relates to a combine.

従来、コンバインは、機体前方の刈取部の先端に分草体を取付けて、圃場の未刈穀稈群に分け入らせて分草しながら刈取作業を行う。この際、圃場を半時計回りに辺縁より中心に向けて刈取走行する所謂回り刈り作業が一般的である。この作業においては、機体左方を未刈穀稈に臨ませての作業となるが、一般に、コンバインは刈取装置を機体左方に寄せて構成している為、未刈穀稈を走行装置によって踏みつけることが無い。   Conventionally, a combine attaches a weeding body to the tip of a cutting part in front of the machine body, and separates it into an uncut grain culm group in the field to perform cutting work while weeding. At this time, a so-called turning-cutting operation is generally performed in which the field is cut and driven in the counterclockwise direction from the edge toward the center. In this work, the left side of the machine is facing the uncut grain cocoon, but in general, the combine is constructed by moving the harvesting device to the left side of the machine, so There is no trampling.

効率的に刈取作業を行う為に、未刈穀稈群を縦貫するように割入る中割り作業においては、機体の左右両側方に未刈穀稈が位置することになる。従って、下記特許文献１に例示するように、小型のコンバインにおいて、右側端部の右側分草体を機体右方位置に切替え、該右側分草体の先端を走行装置の右端よりも右側に位置させて刈取作業を行う技術が知られている。   In order to efficiently perform the cutting operation, in the middle splitting operation so as to pass through the group of uncut grain pods, the uncut grain pods are positioned on both the left and right sides of the machine body. Accordingly, as exemplified in Patent Document 1 below, in a small combine, the right side weed body at the right end is switched to the right side of the body, and the tip of the right side weed body is positioned on the right side of the right end of the traveling device. A technique for performing a cutting operation is known.

また、特許文献２には、右側分草体の前側上方に補助分草ガイドを設けて、操縦者が分草体先端を確認し易くする技術が開示されている。   Patent Document 2 discloses a technique in which an auxiliary weeding guide is provided above the front side of the right weeding body so that the operator can easily confirm the tip of the weeding body.

前記複数の分草体７のうち、機体右側端部の右側分草体７ａは、前記引起装置８の上端に設けた遠隔操作レバー１６により左右方向に回動可能に切替機構１７によって接続している。   Of the plurality of weed bodies 7, the right weed body 7 a at the right end of the machine body is connected by a switching mechanism 17 so as to be turnable in the left-right direction by a remote control lever 16 provided at the upper end of the pulling device 8.

次に、図３、図４、図５に基づき、右側分草体７ａの回動機構について説明する。
右側分草体７ａ、前側分草フレーム１７ａ、後側分草フレーム１７ｂは、刈取下部伝動フレーム１２に固定した後側分草フレーム１７ｂの先端に前側分草フレーム１７ａを左右回動自在に取付けて、該前側分草フレーム１７ａと右側分草体７ａが一体で回動する構成としている。前記前側分草フレーム１７ａ及び後側分草フレーム１７ｂは、両者間に設ける回動支点に向けて開口部を対向させるように、コの字形状の連結部材１８ａ、１８ｂをそれぞれの端部に備える。 Next, the rotation mechanism of the right weed body 7a will be described with reference to FIGS.
The right side weed body 7a, the front side weed frame 17a, and the back side weed frame 17b are attached to the tip of the rear side weed frame 17b fixed to the cutting lower transmission frame 12, and the front side weed frame 17a is attached to the tip of the rear side weed so as to be rotatable left and right. The front weed frame 17a and the right weed body 7a rotate integrally. The front weed frame 17a and the rear weed frame 17b are provided with U-shaped connecting members 18a and 18b at their respective ends so that the openings face each other toward the pivot point provided between them. .

前記連結部材１８ａ、１８ｂを接続ピン１９で縦軸回動自在に接続し、該接続ピン１９を中心に前側分草フレーム１７ａが左右回動する構成とする。そして、連結部材１８ａと一体で設ける回動アーム２０は、連結部材１８ａの回動中心から両側方に突出して、この突出部の一端に、切替機構１７を構成する張出ワイヤ２１を、テンショナースプリング２２を介して取り付け、前記突出部の他端と後側分草フレーム１７ｂとの間には、復帰スプリング２３の前後両端部を接続する。前記連結部材１８ａには、連結部材１８ｂに向けて、並列させた張出側回動規制ボルト２４ａと収納側回動規制ボルト２４ｂを螺合して取り付け、連結部材１８ｂに一体で設ける当接部材２５に先端を当接させる構成としている。この当接部材２５は、右側分草体７ａが、最も機体外側方となる位置で張出側回動規制ボルト２４ａが当接するように後側分草フレーム１７ｂに垂直に設けた面と、機体中央寄りとなる位置で収納側回動規制ボルト２４ｂが当接する傾斜面とを有する屈曲形状に形成する。張出側回動規制ボルト２４ａ及び収納側回動規制ボルト２４ｂは、廻止ナット２６によって長短調節自在な構成とし、当接部材２５との当接位置を調節することで、前側分草フレーム１７ａの回動範囲を調節できる構成としている。   The connecting members 18a and 18b are connected by a connecting pin 19 so as to be rotatable in the vertical axis, and the front weed frame 17a is rotated left and right around the connecting pin 19. Then, the turning arm 20 provided integrally with the connecting member 18a protrudes on both sides from the turning center of the connecting member 18a, and an extension wire 21 constituting the switching mechanism 17 is provided at one end of the protruding portion with a tensioner spring. The front and rear ends of the return spring 23 are connected between the other end of the protruding portion and the rear weed frame 17b. An abutting member provided integrally with the connecting member 18b by screwing and attaching the overhanging side rotation restricting bolt 24a and the storage side turning restricting bolt 24b that are arranged in parallel to the connecting member 18b. The tip is brought into contact with 25. The contact member 25 includes a surface provided perpendicular to the rear weed frame 17b so that the right side weed body 7a is in contact with the overhanging side rotation restricting bolt 24a at a position that is the outermost side of the body, and a center of the body. It is formed in a bent shape having an inclined surface with which the storage side rotation restricting bolt 24b abuts at a position close to it. The overhang side rotation restricting bolt 24a and the storage side turn restricting bolt 24b are configured to be adjustable in length by a lock nut 26, and by adjusting the contact position with the contact member 25, the front weed frame 17a. The rotation range is adjustable.

しかして、前記右側分草体７ａには、補助分草ガイド１４を設け、該補助分草ガイド１４の前端の緩傾斜部１４ａを、前記右側分草体７ａの先端部に、該右側分草体７ａの傾斜に沿わせて回転自在に取付ける。   Thus, the right weed body 7a is provided with an auxiliary weed guide 14, and a gentle slope portion 14a at the front end of the auxiliary weed guide 14 is provided at the tip of the right weed body 7a. Attached so that it can rotate along the slope.

後端の固定部１４ｃを、右側分草体７ａの後部上端であって非作用側である裏面に回転自在に取付け、右側分草体７ａよりも急傾斜となる分草作用部１４ｂによって、緩傾斜部１４ａ及び固定部１４ｃを連結する。このように構成した補助分草ガイド１４の緩傾斜部１４ａを右側分草体７ａの前端部上側面に突出させて設けた前端支持部７ｃの後上がり傾斜姿勢に形成した孔に後方から挿入して軸着し、固定部１４ｃは、緩傾斜部１４ａと同一軸上で右側分草体７ａの背面に側面視Ｌ字形に形成した補助分草ガイドステー７ｂに形成した後上がり傾斜姿勢の孔に挿入して軸着し、板バネ１５を介して締結して取付ける。   The fixed portion 14c at the rear end is rotatably attached to the rear upper end of the right side weed body 7a and is on the non-working side, and the gentle slope portion is formed by the weed action portion 14b that is steeper than the right side weed body 7a. 14a and the fixing | fixed part 14c are connected. Insert the slow inclined portion 14a of the auxiliary weeding guide 14 thus configured from the rear into a hole formed in a rearwardly inclined posture of the front end support portion 7c provided to protrude from the upper side surface of the front end portion of the right weed body 7a. The fixed portion 14c is attached to the shaft, and is inserted into a hole in an upwardly inclined posture formed on the auxiliary weed guide guide 7b formed in an L shape in a side view on the back surface of the right weed body 7a on the same axis as the gently inclined portion 14a. And are attached by fastening via a leaf spring 15.

以上の構成により、補助分草ガイド１４は、緩傾斜部１４ａを右側分草体７ａに沿わせて後側から挿入して軸支しているので穀稈の案内を妨げず、固定部１４ｃを右側分草体７ａの非作用側となる背面に取付けるので、脱粒や塵埃の堆積を防止することができる。   With the above configuration, the auxiliary weeding guide 14 is pivotally supported by inserting the gently inclined portion 14a from the rear side along the right weeded body 7a, so that the guide of the cereals is not hindered, and the fixing portion 14c is placed on the right side. Since it attaches to the back surface which becomes the non-operation side of the weeding body 7a, it can prevent degranulation and accumulation of dust.

固定部１４ｃは、右側分草体７ａに板バネ１５を介して締結して取付けるため、この板バネ１５の弾性力で回動位置を保持でき、任意の位置に調節することができる。
コンバインの刈取作業においては、圃場を半時計回りに辺縁より中心に向けて刈取っていく所謂回り刈り作業が一般的である。この作業においては、機体左方を未刈穀稈に臨ませての作業となるが、一般にコンバインは、刈取装置３を機体左方に寄せて構成している為、未刈穀稈を走行装置２によって踏みつけることが無い。効率的に刈取作業を行う為に、未刈穀稈群を縦貫するように割入る中割り作業においては、機体の左右両側方に未刈穀稈が位置することになる。従って、小型のコンバインでは右側分草体７ａを機体右方に偏倚させて、該右側分草体７ａの先端を走行装置の右端よりも右側に位置させて刈取作業を行う。 Since the fixing portion 14c is fastened and attached to the right weed body 7a via the leaf spring 15, the rotation position can be held by the elastic force of the leaf spring 15 and can be adjusted to an arbitrary position.
In the harvesting operation of the combine, a so-called turning mowing operation in which the field is harvested counterclockwise from the edge toward the center is common. In this work, the left side of the machine body faces the uncut grain cocoon, but in general, the combine is configured by bringing the mowing device 3 to the left side of the machine body, so that the uncut cereal meal machine is driven No stepping on by 2. In order to efficiently perform the cutting operation, in the middle splitting operation so as to pass through the group of uncut grain pods, the uncut grain pods are positioned on both the left and right sides of the machine body. Therefore, in a small combine, the right weed body 7a is biased to the right of the machine body, and the cutting operation is performed with the tip of the right weed body 7a positioned on the right side of the right end of the traveling device.

その際に、補助分草ガイド１４を機体右側に傾動調節した場合、刈取装置３に未刈穀稈が干渉せず、中割り作業を良好に行わせることができる。また、補助分草ガイド１４の最右端は機体右側端よりも内側に位置するので畦際を刈取る際にも畦や壁面等の障害物に干渉することなく作業を行うことができる。   At that time, when the auxiliary weeding guide 14 is tilted and adjusted to the right side of the machine body, the uncut wheat straw does not interfere with the reaping device 3, and the middle splitting work can be performed satisfactorily. In addition, since the rightmost end of the auxiliary weeding guide 14 is located on the inner side of the right side end of the machine body, it is possible to perform work without interfering with obstacles such as reeds and wall surfaces when cutting the reeds.

補助分草ガイド１４を機体進行方向に向けて位置させると、右側分草体７ａよりも大きな掬い角を得ることができ、確実な分草作用によって作業効率が向上するとともに、右側分草体７ａから、緩傾斜部１４ａを経て分草作用部１４ｂへと穀稈を支持しながら案内するので、補助分草ガイド１４の基部で稈身を扱いて脱粒させるような不具合もなく、刈取作業における収穫効率を高めることができる。   When the auxiliary weeding guide 14 is positioned in the aircraft traveling direction, a larger angle than the right weeding body 7a can be obtained, and the working efficiency is improved by the reliable weeding action, and from the right weeding body 7a, Since the cereal is supported and guided to the weeding action part 14b through the gentle slope part 14a, there is no trouble such as handling the slimming at the base part of the auxiliary weeding guide 14, and the harvesting efficiency in the cutting operation is improved. Can be increased.

補助分草ガイド１４を左側に傾動調節すると、右側分草体７ａの左端部よりも該右側分草体７ａの後側に配置される右側端部の引起装置８の穀稈引起経路側へと穀稈を案内できるので、分草された穀稈を引起装置８へ円滑に引継ぐことができるので、刈取作業の能率を向上させることができる。   When the auxiliary weed guide 14 is tilted and adjusted to the left side, the cereals are moved from the left end of the right side weed body 7a to the side of the grain raising path of the pulling device 8 at the right end located on the rear side of the right side weed body 7a. Therefore, it is possible to smoothly take over the cereals that have been weeded to the pulling device 8, so that the efficiency of the cutting operation can be improved.

別実施例について、図８に基づき説明する。
前記補助分草ガイド１４の固定部１４ｃに、分草作用部１４ｂに対して回動軸の反対側となる位置にワイヤ受部１４ｄを設け、前記回動アーム２０と前記補助分草ガイド１４を連結する連動ワイヤ２９を取付けて、ケーブルアウタ２９ａは引起装置８の裏側と後側分草フレーム１７ｂとに固定する。 Another embodiment will be described with reference to FIG.
A wire receiving portion 14d is provided on the fixed portion 14c of the auxiliary weed guide 14 at a position opposite to the rotating shaft with respect to the weed action portion 14b, and the rotating arm 20 and the auxiliary weed guide 14 are connected to each other. The interlocking wire 29 to be connected is attached, and the cable outer 29a is fixed to the back side of the pulling device 8 and the rear weed frame 17b.

回動アーム２０を、前側分草フレーム１７ａが機体右側となる方向に回動させることにより、連動ワイヤ２９がワイヤ受部１４ｄを機体右側に引く構成とし、補助分草ガイド１４は右側分草体７ａに対して左側に傾動調節される。   By rotating the turning arm 20 in the direction in which the front weed frame 17a is on the right side of the machine body, the interlocking wire 29 pulls the wire receiving portion 14d to the right side of the machine body, and the auxiliary weeding guide 14 is provided on the right weed body 7a. The tilt is adjusted to the left side.

この構成により、操縦者が操作席６より遠隔操作レバー１６を操作すると、右側分草体７ａが機体右側へ回動すると共に、補助分草ガイド１４は右側分草体７ａに対して左側に傾動し、前述した中割り作業時に、遠隔操作レバー１６を操作することで右側分草体７ａと補助分草体１４を単一操作によって切替ることができるので、中割り作業を行う為に刈幅を広げて刈取作業を行う際に、補助分草体１４が右側端部の引起装置８の穀稈引起経路側に張出し、円滑に穀稈を案内して、刈取作業の効率を高めることができる。   With this configuration, when the operator operates the remote control lever 16 from the operation seat 6, the right weed body 7a rotates to the right side of the aircraft, and the auxiliary weed guide 14 tilts to the left with respect to the right weed body 7a. Since the right weed body 7a and the auxiliary weed body 14 can be switched by a single operation by operating the remote control lever 16 at the time of the above-mentioned middle split operation, the cutting width is increased to perform the middle split operation. When the work is performed, the auxiliary weeding body 14 projects to the grain raising path side of the pulling device 8 at the right end, smoothly guiding the grains and improving the efficiency of the cutting operation.
