Description

本発明は、多条列の穀稈を刈り取って、刈り取った穀稈の株元側と穂先側とを保持して後方の脱穀機へ搬送する多条刈りのコンバインに関する。   The present invention relates to a multi-row harvesting combine that harvests multiple rows of grain straws, holds the stock side and the tip side of the harvested grain straws, and conveys them to a rear threshing machine.

多条列の穀稈を刈り取って、刈り取った穀稈の株元側と穂先側とを保持して後方の脱穀機へ搬送する多条刈りのコンバインが実用化されている。一般的な多条刈りのコンバインは、穀稈の植付圃場を走行可能な走行機体の前方側に、刈刃装置を備えた前処理部を搭載し、走行機体の後方側に、刈り取った穀稈から穀粒等を分離する脱穀機を搭載している。   A multi-row harvesting combine has been put into practical use in which a multi-row row of culms is harvested, the stock side and the tip side of the harvested cereals are held and conveyed to the rear threshing machine. A general multi-row harvesting combine is equipped with a pre-processing unit equipped with a cutting blade device on the front side of a traveling machine capable of traveling in a cereal planting field, and harvested grains on the rear side of the traveling machine. It is equipped with a threshing machine that separates grains from straw.

そして、前処理部は、棒状爪(タイン)を用いて地上から上方へ植立穀稈を梳き上げる(持ち上げる)引き起し装置と、刈り取った穀稈の株元と穂先側とを保持して後方の脱穀機へ搬送する搬送装置とを備えており、引き起し装置および搬送装置は、前処理部を支持する構造材を兼ねた縦伝動ケースに格納された縦伝動軸から動力を取り出して、収穫速度(走行速度)に応じた速度で駆動される。   And the pre-processing unit holds the lifting device for lifting (raising) the planted culm from the ground using a bar-like nail (tine), and the root and tip side of the harvested cereal A pulling device and a transfer device that extract power from a vertical transmission shaft stored in a vertical transmission case that also serves as a structural material that supports the pretreatment unit. It is driven at a speed corresponding to the harvesting speed (traveling speed).

特許文献1に示されるコンバインは、刈り取った穀稈の株元側をチェーン式の株元搬送体で挟持しつつ、穂先側を爪付きチェーン式(タイン式)の穂先搬送体で緩く保持して平行に搬送する。株元搬送体と穂先搬送体とは等しい速度で駆動され、搬送過程で株元搬送体と穂先搬送体との間隔を広げて穀稈の株元を株元側へ引っ張ることにより、穂先搬送体の棒状爪が穂先側へ梳き上げて穀稈を搬送方向と直角に整列させる。   The combine shown in Patent Document 1 holds the tip side of the harvested cereal with a chain-type stock transporter, while holding the tip side loosely with a chain-type (tine type) tip transporter with a claw. Transport in parallel. The stock transporter and the tip transporter are driven at the same speed, and the tip transporter is pulled by pulling the cereal stock to the stocker side by widening the distance between the stock transporter and the tip transporter during the transporting process. The bar-shaped claws are raised to the tip side and the cereals are aligned at right angles to the conveying direction.

そして、株元搬送体と穂先搬送体との間隔が狭い刈り取り位置では、穂先搬送体から上方へ突き出した穀稈の長さが長過ぎて穂先が不安定なので、穂先搬送体の上方に爪付きチェーン式の上穂先搬送体を追加して設けており、刈り取り直後の穀稈を株元から穂先まで3箇所で保持することにより、穀稈のからみや交差を減じて搬送姿勢を安定させている。穂先搬送体と上穂先搬送体とは、引き起し装置を駆動させるために縦伝動軸から引き起し装置へ向かって立ち上げた縦駆動軸によって循環駆動される。   And, at the cutting position where the distance between the stock transporter and the tip transporter is narrow, the length of the cereal protruding upward from the tip transporter is too long and the tip is unstable, so there is a nail above the tip transporter A chain-type top tip carrier is additionally provided, and by holding the rice straw immediately after cutting at three locations from the stock to the tip, the entanglement and crossing of the rice straw are reduced and the transport posture is stabilized. . The tip carrier and the top carrier are circulated and driven by a vertical drive shaft raised from the vertical transmission shaft and raised toward the device in order to drive the raising device.

特許文献2に示されるコンバインは、走行機体の進行方向右側に運転席を設け、脱穀機の穀稈受け入れ口を進行方向左側に設定しており、株元搬送体と穂先搬送体とで搬送された穀稈を受け取って脱穀機に沿って挟持搬送する脱穀フィードチェーンが走行機体の進行方向左側面に配置されている。   The combine shown in Patent Document 2 is provided with a driver's seat on the right side in the traveling direction of the traveling machine body, and the cereal receiving port of the threshing machine is set on the left side in the traveling direction, and is conveyed by the stock carrier and the tip carrier. A threshing feed chain that receives the cereal meal and holds and conveys it along the threshing machine is arranged on the left side surface in the traveling direction of the traveling machine body.

そして、進行方向右側の条列を刈り取った穀稈を搬送する右穂先搬送体が、刈り取り位置から脱穀フィードチェーンへの受け渡し位置まで一体に連続する一方、中央の条列の穀稈を搬送する中穂先搬送体と左側の条列の穀稈を搬送する左穂先搬送体とが右穂先搬送体の途中位置へY型に合流している。   And while the right-handed tip transport body that transports the cereals that have been harvested from the row on the right side in the traveling direction is continuously integrated from the mowing position to the delivery position to the threshing feed chain, The tip carrier and the left tip carrier that carries the left row of cereals are joined to the middle of the right tip carrier in a Y shape.

特許文献3に示されるコンバインは、特許文献2と同様に、右側条列の穀稈を搬送する右穂先搬送体を脱穀フィードチェーンまで一体に連続させ、中央条列の穀稈を搬送する中穂先搬送体と左側条列の穀稈を搬送する左穂先搬送体とが右穂先搬送体の途中位置へY型に合流している。また、特許文献1と同様に、進行方向右側の刈り取り位置に対応させて右上穂先搬送体を設けているが、右上穂先搬送体は、内側(右から2番目)の引き起し装置から動力を取り出して駆動され、引き起し装置の背面側に配置されて、右穂先搬送体と対向させた位置関係で棒状爪による搬送を行っている。   The combine shown in Patent Document 3 is similar to Patent Document 2 in that the right ear tip conveying body that conveys the right row of cereals is continuously continued up to the threshing feed chain, and the middle tip that conveys the middle row of cereals. The transport body and the left tip transport body that transports the left side row of cereals are joined to the middle position of the right hand transport body in the Y shape. Moreover, like patent document 1, although the upper right tip conveyance body is provided corresponding to the cutting position on the right side in the traveling direction, the upper right tip conveyance body receives power from the inner (second from the right) pulling device. It is taken out and driven, arranged on the back side of the pulling device, and transported by a bar-like nail in a positional relationship facing the right-tip carrier.

近年、コンバインの収穫速度(対地速度)の上昇、刈り取り条数の増大に伴って、前処理部で搬送される穀稈の時間当たり搬送量が増加して、脱穀フィードチェーンに受け渡される穀稈の整列状態を搬送過程で大きく修正することが困難になっており、前処理部で刈り取って搬送開始するまでに、穀稈の姿勢を揃えて整列状態を高めておくことが望まれている。   In recent years, with an increase in the harvesting speed (ground speed) of the combine and an increase in the number of cutting lines, the amount of cereals transported in the pretreatment unit has increased per hour, and the cereals passed to the threshing feed chain It is difficult to largely correct the alignment state in the transport process, and it is desired to align the posture of the cereals and increase the alignment state before cutting and pre-processing by the pre-processing unit.

前処理部では、引き起し装置が梳き上げて姿勢を整えた穀稈を右上穂先搬送体の棒状爪で受け取るので、右上穂先搬送体の棒状爪による拘束が遅れると、穂先が垂れたり、折れ曲がったり、交差してからんだりする穀稈が増えて穀稈の穂先位置がばらつき易いので、右上穂先搬送体は、引き起し装置の拘束を離脱した穀稈を早期に保持できることが望ましい。   In the pre-processing section, the cedar that has been lifted up by the pull-up device is received by the bar-like claws of the upper right-hand tip carrier, so that if the restraint by the bar-like nails of the upper-right tip carrier is delayed, the tip droops or bends. Since the position of the tip of the culm is likely to vary due to an increase in the amount of the culm that is entangled or crossed, it is desirable that the upper right cusp carrier can hold the cereal that has been lifted and released from the restraint of the device at an early stage.

特許文献1に示される前処理部では、引き起し装置の拘束を離れた穀稈の中間高さを右穂先搬送体が速やかに拘束できるが、右上穂先搬送体が右穂先搬送体よりもかなり後方で遅れて穀稈の穂先側を拘束するため、肝心の穂先側で穂先が垂れたり、折れ曲がったり、交差してからんだりする可能性がある。   In the pre-processing unit shown in Patent Document 1, the right tip transporter can quickly restrain the intermediate height of the cereal that has left the restraint of the pulling device, but the upper right tip transporter is considerably more than the right tip transporter. Since the head side of the cereal is restrained late, there is a possibility that the tip may hang down, bend, or entangle with crossing.

特許文献3に示されるコンバインは、一対の引き起し装置の間隔を穀稈の掻き込み経路として確保するとともに、右上穂先搬送体を内側の引き起し装置の背面スペースに収めて隣接状態で配置しているので、引き起し装置の拘束を離れた穀稈の穂先側を右上穂先搬送体によって比較的速やかに拘束できる。   The combine shown in Patent Document 3 secures the space between the pair of pulling devices as a scraping path for the cereals, and arranges the upper right tip carrier in the back space of the inner pulling device and is arranged in an adjacent state Therefore, the tip side of the cereal that has left the restraint of the pulling device can be restrained relatively quickly by the upper right tip carrier.

しかし、右穂先搬送体と対向させた位置関係で右上穂先搬送体を循環させるため、刈り取られた穀稈の穂先側は、右上穂先搬送体の外側を大きく迂回して外側へ強く振り回され、収穫速度が増すと、穂先側に作用する遠心力が増大して穀稈が絡み合ったり損傷したりする可能性がある。右穂先搬送体と対向させた位置関係の右上穂先搬送体が刈り取られた穀稈を小さな回転半径で方向転換するため、穀稈が絡み易いという問題もある。   However, in order to circulate the upper right tip transporter in a positional relationship facing the right tip transporter, the harvested grain tip side is greatly swung around the outer side of the upper right tip transporter and strongly swung outward. When the speed increases, the centrifugal force acting on the tip side increases, and the cereals may be entangled or damaged. There is also a problem that the cereals are easily entangled because the cereals that have been cut off by the right-sided tip transporter in a positional relationship opposed to the right-handed tip transporter change direction with a small turning radius.

また、右上穂先搬送体を引き起し装置の背後に配置して長さにも幅に制約があるため、棒状爪(タイン)を長くして穀稈の拘束量を増すことが困難で、収穫速度の向上に対処できない。   In addition, since the upper right tip carrier is raised and placed behind the device, the length is also limited in width, so it is difficult to increase the amount of restraint of cereals by increasing the length of tine. Can't cope with speed increase.

ところで、特許文献1に示される前処理部は、右上穂先搬送体と右穂先搬送体とが穀稈の掻き込み経路の突き当たり位置に配置されるので、右上穂先搬送体と右穂先搬送体とは並走して穀稈を比較的安定に保持できるが、右穂先搬送体が中間位置を拘束した後に、穀稈束の穂先側を遅れて右上穂先搬送体が拘束するので、収穫速度が増すと、右上穂先搬送体の棒状爪の回転速度も速まり、右穂先搬送体に拘束された穀稈束の穂先側が右上穂先搬送体の棒状爪によって拠り合されて絡み合う可能性が出てくる。さらに、分断された穂先搬送体の間で穀稈の受け渡しが断続的であるため、収穫速度が増すと、ここでも、穀稈が損傷したり穀稈束が絡み合う可能性が出てくる。   By the way, since the pre-processing part shown by patent document 1 is arrange | positioned in the contact | abutting position of the scraping path | route of a grain straw with a right upper ear tip conveyance body and a right ear tip conveyance body, It can run side by side and hold the rice cake relatively stably, but after the right tip transporter restrains the middle position, the top right tip transporter restrains behind the ear tip side of the grain straw bundle, so when the harvesting speed increases Further, the rotation speed of the bar-shaped claws of the upper right-hand tip transport body is also increased, and there is a possibility that the head side of the grain bunches restrained by the right-hand tip transport body is engaged by the bar-like claws of the upper right-hand tip transport body. Furthermore, since the delivery of cereals between the split tip carriers is intermittent, if the harvesting speed is increased, cereals may be damaged or cereal bundles may be entangled.

本発明は、引き起し装置と右上穂先搬送体との間、および右上穂先搬送体と右穂先搬送体との間の穀稈受け渡しの連携が最適化され、刈り取り後、速やかに穀稈の配列状態を揃えて、穀稈の損傷や姿勢の乱れ少なく脱穀フィードチェーンへの受け渡しが可能なコンバインを提供することを目的としている。   The present invention optimizes the linkage of the culm passing between the pulling device and the upper right tip transporter, and between the upper right tip transporter and the right tip transporter, and immediately after harvesting, the arrangement of the cereals The purpose is to provide a combine that can be delivered to the threshing feed chain with the same condition and less damage to the cereal and the posture.

また、中央状列の穀稈の穂先側を保持して搬送する中穂先搬送体35B、および左条列の穀稈の穂先側を保持して搬送する左穂先搬送体35Cは、それぞれ右穂先搬送体35Aと同様に形成して、右穂先搬送体35Aに合流させて配置しており、それぞれの棒状爪で保持して搬送される穀稈を右穂先搬送体35Aによって搬送される穀稈に合流させる。   Further, the middle ear tip transport body 35B that holds and transports the head side of the central row of grain pods, and the left ear tip transport body 35C that holds and transports the tip side of the left row of cereals are respectively transported to the right tip. It is formed in the same manner as the body 35A, and is arranged so as to be joined to the right tip transport body 35A, and the cereals held and transported by the respective rod-shaped claws are joined to the cereals transported by the right tip transport body 35A. Let

また、中穂先搬送体35Bの上方に配置された中上穂先搬送体36B、および左穂先搬送体35Cの上方に配置された左上穂先搬送体36Cは、それぞれ右上穂先搬送体36Aと同様に形成され、それぞれ中穂先搬送体35B、左穂先搬送体35Cに沿って穀稈の穂先側を保持搬送する。   Further, the middle upper tip transport body 36B disposed above the middle tip transport body 35B and the left upper tip transport body 36C disposed above the left tip transport body 35C are respectively formed in the same manner as the upper right tip transport body 36A. , Respectively, hold and carry the tip side of the cereals along the middle tip carrier 35B and the left tip carrier 35C.

ただし、右穂先搬送体35A、右上穂先搬送体36Aによる搬送距離は、中穂先搬送体35B、中上穂先搬送体36Bによる搬送距離や、左穂先搬送体35C、左上穂先搬送体36Cによる搬送距離に比較して長いので、それぞれの搬送速度(搬送体循環速度)は、右穂先搬送体35Aの搬送速度=右上穂先搬送体36Aの搬送速度>中穂先搬送体35Bの搬送速度=中上穂先搬送体36Bの搬送速度>左穂先搬送体35Cの搬送速度=左上穂先搬送体36Cの搬送速度の関係に設定して、刈刃装置31によって同時に刈り取られた穀稈が、中穂先搬送体35B、左穂先搬送体35Cによって右穂先搬送体35Aの同じ位置に合流するようにしている。   However, the transport distance by the right tip transport body 35A and the upper right tip transport body 36A is the transport distance by the middle tip transport body 35B and the middle top tip transport body 36B, and the transport distance by the left tip transport body 35C and the left upper tip transport body 36C. Since it is comparatively long, the respective transport speeds (transport body circulation speeds) are such that the transport speed of the right tip carrier 35A = the transport speed of the upper right tip transport body 36A> the transport speed of the middle tip transport body 35B = the middle top tip transport body. 36B transport speed> left tip transport body 35C transport speed = left top tip transport body 36C transport speed, and the cereals that are simultaneously cut by the cutting blade device 31 are the middle tip transport body 35B, the left tip The carrier 35C is joined to the same position on the right-tip carrier 35A.

The scraping by the scraping belts 33A, 33B, 33C, the pinching by the scraping star wheels 32A, 32B, 32C, and the like are synchronized with the harvesting speed. The driving force transmitted to the drive input pulley 41 is transferred from the vertical transmission shaft 42 stored in the transmission vertical case 42E (FIG. 3) to the horizontal conduction shaft stored in the transmission horizontal case 43E (FIG. 3) by the bevel gear mechanism. 43, and is converted into reciprocating motion to drive the cutting blade device 31.

水平伝動軸43の回転は、伝動縦ケース44E(図3)に収納された縦伝動軸44から、傘歯車機構によって、伝動横ケース(図3)45Eに収納された水平伝動軸45へ伝達され、水平伝動軸45の回転が、それぞれの傘歯車機構を経て、3対6基の引き起し装置22A、22B、22Cへ分配される。   The rotation of the horizontal transmission shaft 43 is transmitted from the vertical transmission shaft 44 stored in the transmission vertical case 44E (FIG. 3) to the horizontal transmission shaft 45 stored in the transmission horizontal case (FIG. 3) 45E by the bevel gear mechanism. The rotation of the horizontal transmission shaft 45 is distributed to the three-to-six pulling devices 22A, 22B, and 22C through the respective bevel gear mechanisms.

The circulating left stock transporter 34C rotates the stir-up star wheel 32C and rotates the stir-up star wheels 32B and 32C meshing with each other. The scraping belts 33B and 33C are driven by pulleys 33e attached to the rotating shafts of the respective scratching star wheels 32B and 32C.

一方、縦伝動軸42の回転は、分岐軸46を経て中株元搬送体34B、中穂先搬送体35B、中上穂先搬送体36Bを駆動するとともに、分岐軸49を経て右株元搬送体34Aおよびこぎ深さ搬送体37を駆動する。循環する中株元搬送体34Bは、噛み合う一対の掻き込みスターホイル32Aを回転させ、掻き込みスターホイル32Aと同軸配置したプーリー33eによって掻き込みベルト33Aを循環させる。   On the other hand, the rotation of the vertical transmission shaft 42 drives the middle stock former transport body 34B, the middle tip transport body 35B, and the middle upper stock transport body 36B via the branch shaft 46, and the right stock former transport body 34A via the branch shaft 49. And the depth transporting body 37 is driven. The circulating medium stock transporter 34B rotates a pair of meshing star wheels 32A that mesh with each other, and circulates the scraping belt 33A by a pulley 33e that is arranged coaxially with the scraping star wheels 32A.

また、縦伝動軸42の回転は、根元側の分岐軸48を経て株元搬送体38と右穂先搬送体35Aとを駆動して循環させる。循環する右穂先搬送体35Aは、従動軸36fを経て駆動スプロケット36pを回転させ、右上穂先搬送体36Aを循環させる。   The rotation of the longitudinal transmission shaft 42 is circulated by driving the stock transporter 38 and the right tip transporter 35A through the branch shaft 48 on the root side. The circulating right tip carrier 35A rotates the drive sprocket 36p via the driven shaft 36f and circulates the right tip carrier 36A.

FIG. In FIGS. 6 to 8, in order to facilitate understanding of the mechanism, illustration of a part of each carrier, sprocket, shaft, and bar-like claw is omitted.

図6に示すように、伝動縦ケース42Eに収納された縦伝動軸42(図5)の回転は、駆動軸35fを経て駆動スプロケット35eを回転させて、右穂先搬送体35Aを循環させる。循環する右穂先搬送体35Aは、従動スプロケット35dを経て従動軸36fを回転させて、右上穂先搬送体36Aを循環させる。   As shown in FIG. 6, the rotation of the vertical transmission shaft 42 (FIG. 5) housed in the transmission vertical case 42E rotates the drive sprocket 35e via the drive shaft 35f and circulates the right tip carrier 35A. The circulating right tip carrier 35A rotates the driven shaft 36f via the driven sprocket 35d to circulate the right tip carrier 36A.

伝動縦ケース42Eに収納された縦伝動軸42(図5)の回転は、分岐ケース49Eに収納された分岐軸49(図5)を経て右株元搬送体34Aを循環させる。循環する右株元搬送体34Aは、従動スプロケット34dを経て掻き込みスターホイル32Aおよび掻き込みベルト33Aを駆動する。   The rotation of the vertical transmission shaft 42 (FIG. 5) accommodated in the transmission vertical case 42E circulates the right stock transporter 34A via the branch shaft 49 (FIG. 5) accommodated in the branch case 49E. The circulating right stock transporter 34A drives the stir-up star wheel 32A and the stir-up belt 33A via the driven sprocket 34d.

図7に示すように、右穂先搬送体35Aの従動スプロケット35dは、従動軸36fによって右上穂先搬送体36Aの駆動スプロケット36pと連結されており、右穂先搬送体35Aが循環すると、駆動スプロケット36pが回転して右上穂先搬送体36Aを循環させる。   As shown in FIG. 7, the driven sprocket 35d of the right tip carrier 35A is connected to the drive sprocket 36p of the upper right tip carrier 36A by a driven shaft 36f, and when the right tip carrier 35A circulates, the drive sprocket 36p Rotates and circulates the upper right tip carrier 36A.

図8に示すように、一対の掻き込みベルト33Aは、掻き込み中心33iへ向かって穀稈を掻き込む。掻き込まれた穀稈は、一対の掻き込みスターホイル32Aの噛み合わせで保持されて株元側を刈刃装置31によって切断される。   As shown in FIG. 8, the pair of scraping belts 33A scrapes the cereals toward the scraping center 33i. The culm that has been raked is held by meshing the pair of raked star wheels 32 </ b> A, and the stock side is cut by the cutting blade device 31.

右上穂先搬送体36Aは、突出・引き込みが可能な棒状爪36nをチェーン36mの駒に所定ピッチで取り付けた爪付きチェーンである。右上穂先搬送体36Aの棒状爪36nは、対向配置されたガイド36gと共働して穀稈を掻き込み、束ねて受け取る。チェーン36mは、駆動スプロケット36p、テンションスプロケット36r、およびアイドルスプロケット36qに掛け回されている。   The upper right tip carrier 36A is a chain with claws in which rod-like claws 36n that can be projected and retracted are attached to a piece of the chain 36m at a predetermined pitch. The rod-like claws 36n of the upper right tip carrier 36A work together with the opposingly arranged guides 36g to scrape and receive bundles of cereals. The chain 36m is wound around the drive sprocket 36p, the tension sprocket 36r, and the idle sprocket 36q.

テンションスプロケット36rは、不図示の付勢機構によって外側へ付勢されてチェーン36mに張力を付与する。アイドルスプロケット36qは、掻き込み中心33iの後方に位置し、駆動スプロケット36pよりも大きく前方へ突き出し、穂先搬送体35Aの搬送面よりもさらに前方に配置される。一方、テンションスプロケット36rは、穂先搬送体35Aの搬送面よりも後方へ後退させて配置される。   The tension sprocket 36r is urged outward by an urging mechanism (not shown) to apply tension to the chain 36m. The idle sprocket 36q is located behind the scraping center 33i, protrudes larger forward than the drive sprocket 36p, and is disposed further forward than the transport surface of the tip transport body 35A. On the other hand, the tension sprocket 36r is disposed so as to be retracted rearward from the conveyance surface of the tip conveyance body 35A.

従って、図3に示すように、一対の引き起こし装置22Aの間隔の中心線上では、右上穂先搬送体36Aが右穂先搬送体35Aよりも前方へ突出して配置され、掻き込みベルト33Aによって掻き込まれた穀稈は、一対の引き起こし装置22Aによる支持を失う前に(または一対の引き起こし装置22Aの支持から離脱した直後に)右上穂先搬送体36Aによって穂先側の高い位置を保持され、その後(またはほぼ同時に)、その中間高さ位置を穂先搬送体35Aによって保持される。   Therefore, as shown in FIG. 3, on the center line of the distance between the pair of raising devices 22A, the upper right tip carrier 36A is arranged to protrude forward from the right tip carrier 35A, and is scraped by the scraping belt 33A. The cereals are held in a high position on the tip side by the upper right tip carrier 36A before losing support by the pair of trigger devices 22A (or immediately after leaving the support of the pair of trigger devices 22A), and thereafter (or almost simultaneously) ), The intermediate height position is held by the tip carrier 35A.

本実施形態のコンバイン10では、進行方向右側の引き起し装置22Aにより引き起された植立穀稈が掻き込みベルト33Aによって掻き込まれて刈刃装置31によって刈り取られ、刈り取られた穀稈は、右穂先搬送体35Aよりも前方に位置させた右上穂先搬送体36Aによって、その上穂先部分が遅れることなく受け取られる。   In the combine 10 according to the present embodiment, the planted culm raised by the pulling device 22A on the right side in the traveling direction is scraped by the scraping belt 33A and cut by the cutting blade device 31. The upper tip portion is received without delay by the upper right tip transport body 36A positioned in front of the right tip transport body 35A.

そして、右上穂先搬送体36Aのチェーン36mが後方に傾斜しているので、右上穂先搬送体36Aにより受取られた穀稈は、滑らかに穂先搬送体35Aに継続して搬送される。これにより、刈り取られた穀稈は、特に遅れ易い進行方向右側の上穂先部分も遅れることなく、中穂先搬送体35B、左穂先搬送体35Cによって搬送される穀稈と合流されて、整然と脱穀機12に供給されることとなり、脱穀機12では、高い精度で脱穀、選別作業を行うことができる。 Since the chain 36m of the upper right tip transport body 36A is inclined backward, the cereals received by the upper right tip transport body 36A are smoothly and continuously transported to the tip transport body 35A. As a result, the harvested cereals are joined with the cereals conveyed by the middle tip conveying body 35B and the left tip conveying body 35C without delaying the upper tip part of the right side of the traveling direction, which is particularly likely to be delayed. Thus, the threshing machine 12 can perform threshing and sorting operations with high accuracy.

また、進行方向右側の引き起し装置22Aにより引き起された穀稈は、近接している右上穂先搬送体36Aにより上穂先部分が遅れることなく受取られて、循環する右穂先搬送体35A及び右株元搬送体34Aによって整然と搬送される。   Further, the cereal buds caused by the pulling device 22A on the right side in the traveling direction are received by the adjacent upper right tip carrier 36A without delay in the upper tip portion, and circulate the right tip carrier 35A and the right It is transported in an orderly manner by the stock transporter 34A.

また、右上穂先搬送体36Aのみならず、中上穂先搬送体36B、左穂先搬送体36Cについてもアイドルスプロケット36q等の回転体が掻き込み中心33iの後方に整列しているので、右穂先搬送体35Aは、掻込み装置33Aで掻き込まれてCで掻き込まれて刈取られる範囲の略々全域の穀稈、をそれぞれ搬送でき、搬送性能を向上することができる。   Further, not only the upper right tip transport body 36A but also the middle upper tip transport body 36B and the left tip transport body 36C, the rotating bodies such as the idle sprocket 36q are aligned behind the scraping center 33i. 35A can each convey substantially the whole cereal of the range that is scraped by the scraping device 33A, scraped by C, and cut, thereby improving the transport performance.

また、右穂先搬送体35Aと右上穂先搬送体36Aとが掻き込み経路の突き当たりで並走して穀稈を拘束するので、対向位置でばらばらに拘束する特許文献3の前処理部に比較して円滑な搬送が開始される。   In addition, since the right tip carrier 35A and the right upper tip carrier 36A run side by side at the end of the scraping path and restrain the cereal, it is compared with the pre-processing portion of Patent Document 3 that restrains loosely at the opposing position. Smooth conveyance is started.

また、右上穂先搬送体36Aは、駆動スプロケット36p、テンションスプロケット36r、アイドルスプロケット36qに掛け回して配置され、アイドルスプロケット36qを前方へ位置させて、それでなくても長い棒状爪(搬送爪)を引き起し装置22Aの間隔に突き出すように循環させるので、直線的に循環させる場合に比較して、穀稈を挟み込むことがない安全な循環位置を引き起し装置22Aの間隔により近づけることができる。   Further, the upper right tip carrier 36A is arranged so as to hang around the drive sprocket 36p, the tension sprocket 36r, and the idle sprocket 36q, and the idle sprocket 36q is positioned forward, and even if it is not, a long rod-like claw (conveying claw) is pulled. Since it circulates so that it protrudes at the interval of raising device 22A, it can raise the safe circulation position which does not pinch grain halves, and can approach the interval of device 22A compared with the case where it circulates linearly.

また、特許文献1に示される前処理部よりも穂先搬送体35Aを後方にずらせて、右上穂先搬送体36Aと株元搬送体34Aとで保持した中間位置を少し遅れて穂先搬送体35Aにより保持させるので、穂先搬送体が上穂先搬送体よりも先行して穀稈を保持させる搬送機構に比較して、搬送される穀稈の姿勢が直線的となり、穂先の垂れ下がり、折れ曲がり、からみ付き等を減らして、穀稈の直立状態、整列状態が改善される。   Further, the tip transport body 35A is shifted rearward from the pre-processing unit shown in Patent Document 1, and the intermediate position held by the upper right tip transport body 36A and the stock transport body 34A is held by the tip transport body 35A with a slight delay. Therefore, compared to the transport mechanism that holds the cedar before the top tip transport body, the tip transport body becomes straighter, the tip hangs down, bends, entangles, etc. By reducing, the upright state and alignment state of the cereals are improved.

また、前処理部16を駆動する縦伝動軸42の根元側から動力を取り出して右上穂先搬送体36Aを駆動するので、縦伝動軸42の下流側の駆動機構は、右上穂先搬送体36Aの負荷を受けなくて済み、長い棒状爪(搬送爪)を用いた先行的な保持によって右上穂先搬送体36Aが増大するにもかかわらず、各駆動軸や軸ケース、傘歯車や歯車ケースを小型化して、伝達効率の高い軽量小型の駆動系を設計できる。長い棒状爪(搬送爪)を用いることにより、短い棒状爪(搬送爪)しか使えない特許文献3の前処理部に比較して、収穫速度の向上への対応が容易である。   Further, since the power is taken out from the root side of the vertical transmission shaft 42 that drives the preprocessing unit 16 and the upper right tip conveying body 36A is driven, the drive mechanism on the downstream side of the vertical transmission shaft 42 is the load of the upper right tip conveying body 36A. The drive shaft, shaft case, bevel gear and gear case are downsized despite the fact that the upper right tip carrier 36A is increased by the advance holding using a long bar-like claw (conveying claw). It is possible to design a light and small drive system with high transmission efficiency. By using a long bar-shaped claw (conveying claw), it is easy to cope with an improvement in the harvesting speed as compared with the pretreatment part of Patent Document 3 in which only a short bar-shaped claw (conveying claw) can be used.

また、特許文献2、特許文献3では従動循環して搬送を担う作業部材に過ぎない右穂先搬送体35Aを駆動力伝達部材に兼用して、右上穂先搬送体36Aを駆動させるので、縦伝動軸42に新たな動力分岐を追加することなく、また、専用の動力伝達部材を追加することなく、駆動力伝達系の全体を構成して、部品点数を減らすとともに、高効率に運転させることができる。   Further, in Patent Document 2 and Patent Document 3, the right tip carrier 35A, which is only a working member that is driven and circulated and serves as a transport member, is also used as a driving force transmitting member to drive the right tip carrier 36A. Without adding a new power branch to 42 and without adding a dedicated power transmission member, the entire driving force transmission system can be configured to reduce the number of parts and to operate with high efficiency. .
