まず、この出願の発明は、汎用コンバイン1の刈取前処理装置2によって、ひまわりを刈り取る刈取方法に関するものであって、刈取前処理装置2の下側、すなわち、地面側2aを利用して、車台3の前進に関連してひまわり茎稈を前倒しに押し倒し、その茎稈上部の花托部分を左右一対の分草案内杆4、4に載せて下側の茎稈首部を刈取装置5で刈り取る方法である。   First, the invention of this application relates to a method for harvesting sunflowers by a pre-cutting processing device 2 for a general purpose combine 1, and uses a lower side of the pre-cutting processing device 2, that is, a ground side 2 a to In connection with the forward movement of No. 3, the sunflower stalk is pushed forward and the flower bud part on the upper part of the stalk is placed on the pair of left and right weed guides 4 and 4 and the lower stalk neck is cut by the reaping device 5. is there.

このようにして刈り取ると、ひまわりの茎稈は、安定した状態で適確に首部分が切断され、花托に接続する茎稈を長く付けた状態で刈り取ることが少なくなって花托のみを掻込みオーガー6に供給することができる。   When harvested in this way, the stem of the sunflower is properly cut in a stable state, and it is less likely to be harvested with a long stem attached to the groom. 6 can be supplied.

以下、この発明の実施例を図面に基づいて具体的に説明する。
まず、ひまわりを収穫する汎用コンバイン1は、図1に示すように、クローラ8を装備した車台3上に、茎稈供給口10を前側にして脱穀装置11を搭載し、その茎稈供給口10に搬送コンベヤ12の終端部を接続して構成している。そして、脱穀装置11は、図1の断面図に示すように、上部に螺旋式扱胴13を前後方向に軸架して下側に選別網(受網)14を張設した扱室15を配置し、その下側には、揺動選別棚16を設け、更に、その下方に、選別方向の上手側から順番に、圧風唐箕17、一番移送螺旋18、二番移送螺旋19を軸装し、後部下方に排塵口を開口した選別室20を設けて構成している。
Embodiments of the present invention will be specifically described below with reference to the drawings.
First, as shown in FIG. 1, the general-purpose combine 1 for harvesting sunflowers is equipped with a threshing device 11 on a chassis 3 equipped with a crawler 8 with a stalk supply port 10 on the front side. The terminal part of the conveyor 12 is connected to this. As shown in the sectional view of FIG. 1, the threshing device 11 includes a handling chamber 15 in which a spiral handling cylinder 13 is pivoted in the front-rear direction and a sorting net (receiving net) 14 is stretched downward. A swing sorting shelf 16 is provided on the lower side thereof, and further, on the lower side thereof, in order from the upper side of the sorting direction, the compressed wind tang 17, the first transfer spiral 18 and the second transfer spiral 19 are pivoted. And a sorting chamber 20 having a dust outlet opened below the rear.

つぎに、刈取前処理装置2は、図1、及び図2に示すように、前記搬送コンベヤ12の搬送始端部にテーブル7を連結して設け、このテーブル7上に横向きにして横軸21に軸架した掻込みオーガー6を有する構成としている。そして、刈取前処理装置2は、図面に示すように、上記テーブル7の前側に刈取装置5を設け、この刈取装置5が刈り取った茎稈上部の花托部を、上記掻込みオーガー6が搬送過程で収集しながら、前記搬送コンベヤ12の搬送始端部に供給する構成としている。   Next, as shown in FIG. 1 and FIG. 2, the pre-cutting processing device 2 is provided with a table 7 connected to the transfer start end of the transfer conveyor 12, and placed horizontally on the table 7 on the horizontal shaft 21. It has the structure which has the stroking auger 6 mounted on the shaft. Then, as shown in the drawing, the pre-cutting processing device 2 is provided with a cutting device 5 on the front side of the table 7, and the scraping auger 6 transports the flower portion of the upper portion of the pedicles cut by the cutting device 5. In this case, the toner is supplied to the transfer start end of the transfer conveyor 12 while collecting.

図面において、22は掻込みリールを示している。
つぎに、分草案内杆4,4は、図1、及び図2に示すように、左右一対からなり、後部を刈取装置5の両側近傍において、テーブル7に取り付けて設け、左右両側でひまわりの茎稈部分を挟んだ状態にして案内しながら花托部を上側に載せるように後方に送る構成としている。この場合、左右一対の分草案内杆4,4は、人が両手の平で壊れ易いものを大切に扱う如く、ひまわりの花托を載せて案内、保持するように作用し、前述した刈取装置5が茎稈の首部に相当する部位を刈り取るように構成している。
In the drawing, reference numeral 22 denotes a take-up reel.
Next, as shown in FIG. 1 and FIG. 2, the weed guide rods 4, 4 are a pair of left and right, and are provided with rear portions attached to the table 7 in the vicinity of both sides of the cutting device 5, The arrangement is such that the floret part is sent back so that the stem part is placed on the upper side while guiding the stem part. In this case, the pair of left and right weed guide rods 4 and 4 act to place and guide the sunflower buds so that a person can handle the fragile ones with palms easily. Is configured to reap a portion corresponding to the neck of the stem.

なお、上記刈取装置5は、図5に示すように、レシプロ式の刈刃に代えて鋸刃状の固定刃5aを設けると、切れ味が良くなるのは勿論であるが、加えてコストが安くなる利点と、車台3の振動が大幅に低減される特徴がある。   In addition, as shown in FIG. 5, when the cutting device 5 is provided with a saw blade-shaped fixed blade 5a instead of a reciprocating type cutting blade, the sharpness is improved, but the cost is low. There is an advantage that the vibration of the chassis 3 is greatly reduced.

つぎに、茎稈株元切断装置25は、図1に示すように、左右に配置したクローラ8の中間部位にある走行ミッション装置26の前側に取り付けてモータ27で駆動する構成にしている。したがって、茎稈株元切断装置25は、図1の側面視において、クローラ8の前端部より前側に位置する関係に構成している。   Next, as shown in FIG. 1, the stem and stalk base cutting device 25 is configured to be attached to the front side of the traveling mission device 26 at the intermediate portion of the crawler 8 arranged on the left and right and to be driven by the motor 27. Therefore, the stem-and-strain-source cutting device 25 is configured to be positioned in front of the front end portion of the crawler 8 in the side view of FIG.

そして、刈取前処理装置2は、図3に示すように、地面側2aを利用して刈取直前の長いひまわり茎稈を前方側に押し倒すとき、その地面側2aとひまわり茎稈の倒伏角度とが略平行状態になる傾斜角度を持たせて茎稈を案内する構成としている。   Then, as shown in FIG. 3, the pre-cutting processing device 2 uses the ground side 2a to push the long sunflower stalk just before cutting forward, and the ground side 2a and the lying angle of the sunflower stalk are determined. It is set as the structure which guides the stem with the inclination angle which becomes a substantially parallel state.

そして、刈取前処理装置2は、図4に示すように、テーブル7の上面側2bの傾斜度を、前部の刈取装置5とクローラ8の接地前端部とを結んだ仮想直線イに比較して大きな傾斜角度を持たせて構成している。   As shown in FIG. 4, the pre-cutting processing device 2 compares the inclination of the upper surface side 2b of the table 7 with a virtual straight line A connecting the front cutting device 5 and the grounding front end of the crawler 8. With a large inclination angle.

このように、刈取前処理装置2は、図3に示すように、地面側2aを茎稈の倒伏角度と平行になるように合わせ、図4に示すように、上面側2bを仮想直線イより大きな傾斜角に構成したから、前者の実施例では、ひまわりの長い茎稈が、無理に前方側に押し倒されるのではなく、地面側2aに密着した状態で押し倒され、茎稈に損傷を与えることがほとんどない特徴がある。   In this way, the pre-cutting processing device 2 matches the ground side 2a so as to be parallel to the inclination angle of the stalk as shown in FIG. 3, and the upper surface side 2b from the virtual straight line A as shown in FIG. In the former embodiment, the long stem of the sunflower is not pushed down to the front side, but is pushed down in close contact with the ground side 2a and damages the stem. There are few features.

そして、この実施例は、花托の刈取時に、長い茎稈部分が刈取前処理装置2の地面側2aに密着して保持されるから、刈取作用が適確にできる特徴もある。
そして、後者の実施例は、刈取装置5によって刈り取られた花托は、傾斜角度の大きい上面側2bに沿って掻込みオーガー6側に、淀むことなく円滑に流れ込んで掻き込まれる特徴がある。そして、実施例は、花托を刈取位置から掻込みオーガー6へ適確に受け継がせて掻き込み、搬送コンベヤ12に供給できるものとなっている。
In addition, this embodiment also has a feature that the cutting action can be properly performed because the long stem portion is held in close contact with the ground side 2a of the pre-cutting processing device 2 when the floret is cut.
The latter embodiment is characterized in that the florets cut by the reaping device 5 smoothly flow into the stirrer auger 6 side along the upper surface 2b having a large inclination angle without being stagnated. In the embodiment, the florets are appropriately handed over from the cutting position to the take-in auger 6 and taken in, and supplied to the conveyor 12.

上記のように構成されて特有の機能を有する実施例は、圃場に列状に植えられて生育しているひまわりを刈り取るにあたり、車台3の前進に伴って前記刈取前処理装置2の地面側2aを利用してそのひまわりの長い茎稈を前方に押し倒しながら、茎稈上部の花托を左右一対の分草案内杆4、4で挟んで、人が手の平に物を載せるように、上面に載せて保持し安定した状態で茎稈首部を刈り取ることができる特徴がある。そして、ひまわりの長い茎稈は、無理に前方側に押し倒されるのではなく、刈取前処理装置2の地面側2aに密着した状態で押し倒されるから、茎稈に損傷を与えることがほとんどない特徴がある。更に加えて、実施例は、花托の刈り取り時には長い茎稈部分が地面側2aに密着して保持された状態で刈り取られることによって、刈り取り作用も適確にできるものとなっている。   In the embodiment configured as described above and having a specific function, when the sunflowers that are planted and grown in rows in the field are harvested, the ground side 2a of the pre-treatment device 2 for cutting as the chassis 3 advances. While pushing down the long stalk of the sunflower forward using the, sandwich the flower bud on the top of the stalk between the pair of left and right weed guides 4 and 4 and place it on the top so that people can put things on the palm It is characterized by the ability to reap the stem and neck in a stable state. And since the long stem of a sunflower is not pushed down to the front side forcefully, it is pushed down in the state closely_contact | adhered to the ground side 2a of the cutting pretreatment apparatus 2, The feature which hardly damages a stem is included. is there. In addition, in the embodiment, when the floret is trimmed, the trimming portion is trimmed in a state where the long stem bud portion is held in close contact with the ground side 2a, so that the trimming action can be appropriately performed.

そして、この実施例は、花托にできる限り茎稈を付けないように短く刈り取ることによって、花托のみを供給して脱穀装置11に負担をかけることを少なくする点にも従来型と違う特徴がある。   This embodiment also has a feature that is different from the conventional type in that it reduces the burden on the threshing device 11 by supplying only the florets by cutting the florets as short as possible without attaching stem buds as much as possible. .

つぎに、刈取前処理装置2は、図6、及び図7に示す実施例の場合、テーブル7の地面側2aに、側面視で掻込みオーガー6の下方に相当する部分を下側に膨らせた凸状のガイド板24を下方位置に取り付け、ひまわりの長い茎稈を前方側に押し倒しができるように構成している。   Next, in the embodiment shown in FIG. 6 and FIG. 7, the pre-cutting processing device 2 bulges a portion corresponding to the lower side of the stirrer auger 6 in the ground side 2 a of the table 7 downward. A raised convex guide plate 24 is attached to the lower position so that the long stem of the sunflower can be pushed forward.

このように、ガイド板24は、テーブル7の地面側2aに取り付けると、刈取作業中に長い茎稈を前倒しにする機能を発揮するのは勿論であるが、刈取前処理装置2の前部を搬送コンベヤ12側から分離したとき、図7に示すように、スタンド代わりに使用することもできる実用的な効果がある。   As described above, when the guide plate 24 is attached to the ground side 2a of the table 7, the front plate of the pre-cutting processing device 2 is of course provided with the function of bringing the long pedicles forward during the cutting operation. When separated from the conveyor 12 side, there is a practical effect that can be used instead of a stand as shown in FIG.

つぎに、茎稈株元切断装置25は、図8に示す実施例の場合、走行ミッション装置26に取り付けて、クローラ8の前側に位置させた構成としている。
従来の構成では、第二刈刃をテーブルに接近させて、すぐ後側に設けており、第一刈刃との刈取タイミングが、第一刈刃より先に第二刈刃が刈り取る場合があり、第一刈刃の刈取不良が多く発生していた。
Next, in the case of the embodiment shown in FIG. 8, the stem and stem stock cutting device 25 is attached to the traveling mission device 26 and is located on the front side of the crawler 8.
In the conventional configuration, the second cutting blade is close to the table and provided immediately behind, and the cutting timing with the first cutting blade may be cut by the second cutting blade before the first cutting blade. Many cutting failures occurred with the first cutting blade.

それに対して、上記実施例は、茎稈株元切断装置25が、ひまわりの長い茎稈にも充分に対応できて、前部の刈取装置5の刈取時よりタイミング的に先に刈り取る等の不都合が起きない利点がある。   On the other hand, in the above-described embodiment, the stem and stalk base cutting device 25 can sufficiently cope with the long stem of the sunflower, and the inconvenience such as cutting the timing earlier than when the front reaping device 5 is reaped. There is an advantage that does not occur.

つぎに、図9、及び図10に示す第二刈刃31の実施例は、図面から解るように、チエンソー式に構成してテーブル7の背後に横方向に沿わせて車台3の右側部まで延長して回転駆動可能に設け、刈取作用と同時に刈取茎稈を横搬送して車台3の側部位置に排出できる構成としている。   Next, the embodiment of the second cutting blade 31 shown in FIG. 9 and FIG. 10 is configured as a chain saw type and extends laterally behind the table 7 to the right side of the chassis 3 as can be seen from the drawings. It extends so that it can be driven to rotate, and at the same time as the mowing action, the mowing stem is laterally conveyed and discharged to the side position of the chassis 3.

このように構成した実施例は、切断時の振動を少なくして適確に刈り取りができる利点と同時に刈取後の茎稈を車台の側方に排出できるから事後の収集作業がやり易い特徴がある。   The embodiment configured as described above has an advantage that the vibration at the time of cutting is reduced and can be properly cut, and at the same time, the stems after cutting can be discharged to the side of the chassis so that the subsequent collection work is easy. .

つぎに、掻込みリール22の下降作動について実施例を説明する。
通常、掻込みリール22は、圃場の茎稈の高さ(茎稈の丈)に応じて上下に昇降調節して丈に合わせて掻き込み作業ができる構成としているが、ひまわり用汎用コンバイン1は、刈取装置5の上方に分草案内杆4,4があるから、これとの間隔を適正に保たせる必要がある。
Next, an example of the lowering operation of the take-in reel 22 will be described.
Normally, the take-up reel 22 is configured so that it can be moved up and down according to the height of the stalks (the length of the stalks) in the field and can be scraped according to the height. Since there are the weed guide rods 4 and 4 above the cutting device 5, it is necessary to keep the distance between them properly.

そして、汎用コンバイン1は、掻込みリール22を下げ過ぎると、回転するリールタイン35が分草案内杆4,4と干渉し、逆に、離れ過ぎると掻込み作用ができず、常に、適正な間隔を保持することが要求される。そこで、実施例は、掻込みリール22に下限停止位置を設定して、下げ工程で分草案内杆4,4との適正間隔の位置で自動停止できる構成としている。   When the take-up reel 22 is lowered too much, the general purpose combine 1 causes the rotating reel tine 35 to interfere with the weed guide rods 4 and 4. It is required to maintain the interval. Therefore, in the embodiment, a lower limit stop position is set on the take-up reel 22 and the stop can be automatically stopped at a position at an appropriate interval from the weed guide rods 4 and 4 in the lowering process.

そこで、実施例の掻込みリール22は、図19、及び図20に示すように、上下シリンダ50を伸縮操作するリール昇降スイッチ51を操作レバー52のグリップ部に設け、このスイッチ操作で昇降調節ができる構成としている。そして、前記上下シリンダ50は、下限位置と上限位置とにリミットスイッチを設けて上下の自動停止位置を設定している。   Accordingly, as shown in FIGS. 19 and 20, the take-up reel 22 of the embodiment is provided with a reel lifting / lowering switch 51 for extending and retracting the upper and lower cylinders 50 in the grip portion of the operating lever 52, and the lifting / lowering adjustment can be performed by operating this switch. It is configured as possible. The upper and lower cylinders 50 are provided with limit switches at the lower limit position and the upper limit position to set the upper and lower automatic stop positions.

このように構成した掻込みリール22は、図20に示すリール昇降スイッチ51を押し操作して下降するとき、上下シリンダ50が下限リミットスイッチに達すると自動的に停止して分草案内杆4,4との適正な上下間隔を保持できるものである。   When the reeling up / down switch 51 shown in FIG. 20 is pushed down and the lowering cylinder 51 reaches the lower limit switch when the reeling up / down switch 51 shown in FIG. 4 can maintain an appropriate vertical distance.

したがって、実施例の掻込みリール22は、分草案内杆4,4との間に、常に適正な間隔が保てるから、ひまわりの花托部に対して適確な掻き込み作用ができ、ヘッドロスを大幅に低減できる優れた効果を有するものとなった。   Therefore, the scraping reel 22 of the embodiment can always keep an appropriate distance between the weed guide rods 4 and 4, so that it can perform an appropriate scraping action on the flower bud portion of the sunflower and greatly reduce the head loss. It has an excellent effect that can be reduced.
