Description

本発明は、農業機械の技術分野に属し、多条刈のコンバインにおける穀稈搬送装置に関するものである。 The present invention belongs to the technical field of agricultural machinery, and relates to a grain feeder in a multi-row cutting combine.

従来から多条刈コンバインの刈取前処理装置は、前部の複数器の穀稈引起し装置の後方に、掻込みスタ−ホイ−ルと、掻込みベルトと、弾性ガイド杆等から構成した掻込搬送装置と、これらに後続する株元搬送装置と穂先搬送装置とから構成され、圃場に成育している多条の穀稈条列を一度に刈取って合流搬送しながら脱穀装置に供給する構成となっている。 Conventionally, a pre-cutting device for a multi-row harvesting combine has a scraper wheel, a scraper belt, an elastic guide rod, and the like behind a plurality of grain raising devices at the front. It is composed of an embedded transport device, a stock transport device and a tip transport device that follow these, and feeds the threshing device while harvesting and transporting multiple rows of grain ridges growing on the field at once. It has a configuration.

このような従来装置において、掻込搬送装置における平面視、略菱形形状の弾性素材から構成された穀稈ガイドは、掻込搬送に伴って穀稈を対向側の掻込みスタ−ホイ−ル等に弾性力で押圧して抜け落ち等を起こさず確実に後方に送るために重要な役目を果たしている。
特開平８−１９６１３２号公報 In such a conventional apparatus, the culm guide made of an elastic material having a substantially rhombus shape in plan view in the rake conveying device is used to squeeze the culm into the opposite side, such as a stirrer star wheel on the opposite side. It plays an important role in ensuring that it can be fed backwards without being pulled out by being pressed with elastic force.
JP-A-8-196132

従来から刈取前処理装置の掻込搬送装置は、上記特許公開公報に開示されているように、刈取直前から刈取に至る穀稈を掻込みスタ−ホイ−ルや掻込みベルトに案内する上下のガイドは、掻込みスタ−ホイ−ル側に対応させたガイドを弾性素材とし、掻込みベルト側に対応するガイドを剛体とした構成が示されている。 Conventionally, as shown in the above-mentioned patent publication, the scraping and transporting device of the pre-cutting processing device is an upper and lower guide that guides the culm from just before cutting to the cutting starwheel or the driving belt. The guide has a structure in which the guide corresponding to the stirrer wheel side is made of an elastic material and the guide corresponding to the stirrer belt side is rigid.

この場合、ガイドは、上記公報の説明、及び図１から明らかなように、上側（ベルト側）が剛体で形成したガイドで、下側（スタ−ホイ−ル側）が弾性素材のガイドで構成されていることが解る。 In this case, as is apparent from the description of the above-mentioned publication and FIG. 1, the guide is a guide formed on the upper side (belt side) by a rigid body, and the lower side (star wheel side) is a guide made of an elastic material. I understand that it is.

そこで、圃場の穀稈は、刈取直前から刈取直後にかけてスタ−ホイ−ル等からなる掻込搬送装置に誘導案内する場合、複数本のガイドを穀稈の稈身方向に沿わせて上下に配置する構成では、上部（穂先に近い側）を固くしたり、剛体で構成し、逆に、株元側の弾性力を、上側ガイドより弱くすると、搬送姿勢の乱れや抜け落ち、脱落が起こって円滑な穀稈誘導ができない課題がある。 Therefore, when the cereal straw in the field is guided and guided to the stirrer / conveyor consisting of a star wheel or the like immediately before cutting and immediately after cutting, multiple guides are arranged vertically along the slimming direction of the grain straw. In this configuration, if the upper part (side closer to the tip) is hardened or made of a rigid body, conversely, if the elastic force on the stock side is weaker than the upper guide, the transport posture will be disturbed, fallen off, and fall off smoothly. There is a problem that can not be induced.

しかしながら、上述の公知例の構成は、他の構成要件（終端部分をスタ−ホイ−ルの谷部に沿わせて近接する等の手段）と合わせて、優れた掻込、誘導作用が想定できる。
つぎに、この種の刈取前処理装置の掻込搬送装置は、掻込みスタ−ホイ−ルの支持構成や他のチエンガイドの取付支持構成、更には、掻込みスタ−ホイ−ルの下側近傍にある刈取装置の伝動部等に掻込穀稈が絡んだり、巻き付く課題もあり、これらの解決が要望されている。 However, the configuration of the above-described known example can be expected to have excellent scavenging and inductive action in combination with other constituent elements (means such as bringing the terminal portion close to the valley of the star wheel). .
Next, this kind of pre-cutting device scraping and transporting device has a support structure for a scraping star wheel, a mounting support structure for other chain guides, and a lower side of the trapping star wheel. There is also a problem that a chopped cereal entangles or winds around a transmission portion of a reaping device in the vicinity, and these solutions are desired.

In this case, as shown in FIG. 22, the depth sensors 46a and 46b are attached to the sensor box 59 attached to the slide device 57, and detect the tip of the cereals to be conveyed. The detection signal is input to the controller.

そして、上記スライド装置５７は、図１９、乃至図２１に示すように、操作レバ−６０が下向きに取り付けられ、操縦座席２２からオペレ−タ−によって調節操作ができる構成としている。そして、支持装置５６は、図２２に示すように、張圧用のスプリング６１をスライド装置５７の上側に設けた樹脂製カラ−６２との間に介装して設け、そのスライド装置５７を上下から挟んで取付部材５５側に張圧して構成している。そして、実施例の場合、スプリング６１の張圧力は、全圧縮に達する前の少し余裕を保った張圧力とし、操作レバ−６０を握って調節するときにはスライド装置５７が張圧力に抗してスム−スに移動でき、それ以外のときには張圧力で調節位置を確実に保持できる程度に構成している。 As shown in FIGS. 19 to 21, the slide device 57 is configured such that an operation lever 60 is attached downward and an adjustment operation can be performed from the control seat 22 by an operator. As shown in FIG. 22, the support device 56 is provided with a tension spring 61 interposed between a resin collar 62 provided on the upper side of the slide device 57, and the slide device 57 is viewed from above and below. It is configured by tensioning to the mounting member 55 side. In the case of the embodiment, the tension pressure of the spring 61 is a tension pressure that maintains a slight margin before reaching the full compression, and when adjusting by grasping the operation lever 60, the slide device 57 resists the tension pressure. -It is constructed to such an extent that it can be moved to the stand and, in other cases, the adjustment position can be securely held by the tension pressure.

このようにして、扱深さセンサ４６ａ、４６ｂは、穀稈の稈身方向に調節できる構成で、穀稈丈に対応して、長稈（最も浅扱ぎ位置を示す図２０参照）の圃場、又は短稈（最も深扱ぎ位置を示す図１９参照）の圃場に応じて穀稈の稈身方向に予め調節しておき、扱深さ制御装置４５を利用して実態に合わせて適切に刈取脱穀作業を行なうことができる。 In this way, the handling depth sensors 46a and 46b can be adjusted in the slimming direction of the culm, and correspond to the culm length, and the field of the long culm (see FIG. 20 showing the shallowest handling position). Or, it is adjusted in advance in the slimming direction of the culm according to the field of the short culm (see FIG. 19 showing the deepest handling position), and appropriately using the handling depth control device 45 to suit the actual situation Cutting and threshing can be performed.

以上のように、実施例に係る扱深さセンサ４６ａ、４６ｂの調節装置４７は、狭いスペ−スを利用した簡潔な構成であって、穀稈の絡みつきやひっかかりが少ない特徴がある。特に、操作レバ−６０は、下向きに構成することにより、操縦座席２２からの調節操作が楽になると共に、穀稈等が絡み付こうとしても下向きに形成しているから、下方に滑り落ちて絡むことがない特徴がある。 As described above, the adjusting device 47 of the working depth sensors 46a and 46b according to the embodiment has a simple configuration using a narrow space, and has a feature that there is little entanglement and catching of the cereal. In particular, the operation lever 60 is configured to face downward, so that the adjustment operation from the control seat 22 is facilitated, and even if an attempt is made to entangle cereals or the like, the operation lever 60 is formed downward. There is no feature.

更に、スライド装置５７は、スプリング６１の張圧力によって適度に張圧しており、スライド操作が容易でありながら、固定保持力が安定する利点がある。
つぎに、刈取フレ−ム２４の支持機構について説明する。 Further, the slide device 57 is moderately tensioned by the tension pressure of the spring 61, and has an advantage that the fixed holding force is stabilized while the sliding operation is easy.
Next, a support mechanism for the cutting frame 24 will be described.

まず、刈取フレ−ム２４は、図２３、乃至図２５に示すように、後部に連結した入力伝動ボックス６５を車体２の前側上部に設けた広幅懸架台６６の右側上に支持具６７を介して連結支持して設け、原動側から入力された回転動力を先端側の刈取装置１５、穀稈引起し装置２６、各搬送装置６、６、９に伝動する構成としている。そして、入力伝動ボックス６５は、左外側に延長して設けた支持軸６８の端部を横側支持具６９によって前記広幅懸架台６６の左側上に支持して構成している。そして、連結用サイドフレ−ム７０は、図２３、及び図２５に示すように、上部を前記支持軸６８の横側支持具６９より内側に連結し、下部を入力伝動ボックス６５から前方に延長した先端側の刈取フレ−ム２４に連結して３部材２４、６５、６８を一体に枠組した構成としている。 First, as shown in FIGS. 23 to 25, the cutting frame 24 has an input transmission box 65 connected to the rear part on the right side of a wide suspension base 66 provided on the upper front side of the vehicle body 2 via a support 67. The rotational power input from the driving side is transmitted to the cutting device 15 on the tip side, the grain raising device 26, and the transport devices 6, 6, 9. The input transmission box 65 is configured such that an end portion of a support shaft 68 extended to the left outer side is supported on the left side of the wide suspension base 66 by a lateral support tool 69. As shown in FIGS. 23 and 25, the connecting side frame 70 has an upper portion connected to the inner side of the lateral support 69 of the support shaft 68 and a lower portion extended forward from the input transmission box 65. The three members 24, 65, and 68 are integrated with the cutting frame 24 on the distal end side to form a frame.

このように、刈取フレ−ム２４は、後端に連結している一体の入力伝動ボックス６５が支持具６７によって、更に、その横側に延長した一体構成の支持軸６８が横側支持具６９によって、それぞれ広幅懸架台６６上の右側と左側とに固着支持された構成となっている。 As described above, the cutting frame 24 has the integral input transmission box 65 connected to the rear end by the support 67 and the integral support shaft 68 extended laterally by the support 67. Thus, the right and left sides of the wide suspension base 66 are fixedly supported.

したがって、刈取フレ−ム２４は、補強部材を同一の軸芯に構成しており、回動支点を中心にして上下の回動が円滑にできる利点がある。そして、実施例に係る刈取フレ−ム２４は、２つの支持具６７、６９によって、広幅懸架台６６に連結固着すると共に、連結用サイドフレ−ム７０を利用して、支持軸６８を一体構成にしたから、作業中に受ける強い衝撃、例えば、分草杆２５の先端が畦に衝突する等の強い力にも耐えることのできる強固な枠組み構成となった特徴がある。 Accordingly, the cutting frame 24 has the advantage that the reinforcing member is formed on the same axis, and the vertical rotation can be smoothly performed around the rotation fulcrum. The cutting frame 24 according to the embodiment is connected and fixed to the wide suspension base 66 by the two supports 67 and 69, and the support shaft 68 is integrated with the connecting side frame 70. Therefore, there is a feature that the frame structure is strong enough to withstand a strong impact received during the work, for example, a strong force such that the tip of the weed fence 25 collides with the fence.

このように、実施例は、刈取フレ−ム２４と補強部材とを一体構成としているから、刈取作業中に刈取フレ−ム２４が振動したり、騒音を発する等の異常な現象も未然に防止できる特徴がある。 As described above, since the cutting frame 24 and the reinforcing member are integrally formed in the embodiment, abnormal phenomena such as vibration or noise generation of the cutting frame 24 during the cutting operation can be prevented. There are features that can be done.

つぎに、フィ−ドチエンオ−プン式の構成において、刈取側の供給チエン７５の終端部分とフィ−ドチエン７６の始端部分との間にあって穀稈株元を外側に案内する株元ガイド杆７７に関するものである。この場合、株元ガイド杆７７は、フィ−ドチエン７６を連結支持している回動ア−ム７８に取付部材７９を介して基部を連結し、フィ−ドチエン７６のオ−プン回動とともに逆側（前記供給チエン７５の下側）に回動する構成としている。 Next, in the feed chain open type structure, the stock base guide rod 77 is located between the terminal portion of the cutting chain 75 on the cutting side and the start portion of the feed chain 76 and guides the grain stock source to the outside. It is. In this case, the stock guide guide 77 has a base connected to a rotation arm 78 that connects and supports the feed chain 76 via an attachment member 79, and reverses as the feed chain 76 opens. It is configured to rotate to the side (below the supply chain 75).

既に、広く知られているように、フィ−ドチエン７６は、始端部を支点にして後部を外側にオ−プン回動して、脱穀装置２１との間に作業空間を作り、メンテナンスを容易に行なうことができる構成としている。 As already well known, the feed chain 76 opens and rotates the rear part outward with the start end as a fulcrum to create a work space between the threshing device 21 and facilitate maintenance. It is set as the structure which can be performed.

実施例の場合、フィ−ドチエン７６は、脱穀装置２１の前部外側に固定された支持腕８０に、支持ピン８１によって回動自由に連結した回動ア−ム７８に連結支持し、搬送始端側を回動支点（支持ピン８１を支点とする。）にしてフィ−ドチエンオ−プンができる構成としている。そして、前記株元ガイド杆７７は、上記回動ア−ム７８の前側に取付部材７９によって取り付け、刈取側の供給チエン７５の終端部分下側にまで延長して脱穀装置２１へ供給されて受継ぐ穀稈の株元部分を外側に案内する形状に構成している。したがって、搬送穀稈は、供給チエン７５の終端部分からフィ−ドチエン７６の始端部に受け継がれるときに前記株元ガイド杆７７によって株元が外側に向くように案内されて、フィ−ドチエン７６上に載るように供給される。 In the case of the embodiment, the feed chain 76 is connected and supported to a support arm 80 fixed to the front outer side of the threshing device 21 by a support arm 81 and freely connected to a turn arm 78, and the conveyance start end. The side is set as a rotation fulcrum (support pin 81 is used as a fulcrum) so that the feed chain can be opened. The stock guide rod 77 is attached to the front side of the rotating arm 78 by an attachment member 79, extended to the lower side of the terminal portion of the supply chain 75 on the cutting side and supplied to the threshing device 21. It is configured in a shape that guides the stock portion of the cereals to be joined to the outside. Therefore, the transporting culm is guided by the stock source guide rod 77 so that the stock is directed outward when it is inherited from the end portion of the supply chain 75 to the start end of the feed chain 76, so that the Supplied to be mounted on.

そして、本案実施例で重要な構成要件は、支持腕８０と支持ピン８１と回動ア−ム７８との３部材の連結支持部分の構成が、図２８に示すように、前傾状態に傾斜して前記供給チエン７５の搬送方向（傾斜方向）に対して略直交状態を保つ構成であることが必要である。 An important component in the present embodiment is that the configuration of the connecting support portion of the three members of the support arm 80, the support pin 81, and the rotation arm 78 is inclined forward as shown in FIG. Thus, it is necessary to have a configuration that maintains a substantially orthogonal state with respect to the conveying direction (inclination direction) of the supply chain 75.

したがって、株元ガイド杆７７は、支持腕８０の支持ピン８１を回動支点にして回動ア−ム７８を一体に外側に向けて回動してフィ−ドチエン７６をオ−プン回動すると、逆に、内側に向かって回動する。このように、株元ガイド杆７７は、回動ア−ム７８を外側に回動させてオ−プンするとき、逆に、回動ア−ム７８によって内側に回動され、供給チエン７５の下側をそのチエンと衝突しない関係位置（間隔）を保持しながら回動できる。 Accordingly, the stock guide rod 77 rotates the feed arm 76 open by rotating the pivot arm 78 integrally outward with the support pin 81 of the support arm 80 as a pivot point. Conversely, it turns inward. As described above, when the stock guide guide 77 is opened by turning the turning arm 78 outward, the stock guide guide 77 is turned inside by the turning arm 78. The lower side can be rotated while maintaining a related position (interval) that does not collide with the chain.

このようにして、本案実施例に係るフィ−ドチエン７６は、オ−プン回動の範囲を従来構成より大幅に広くすることができるため、作業空間（場所）が広くなってメンテナンス作業が楽にできる特徴がある。 In this way, the feed chain 76 according to the embodiment of the present invention can make the open rotation range significantly wider than that of the conventional configuration, so that the work space (place) is widened and the maintenance work can be facilitated. There are features.

つぎに、脱穀装置２１の排藁搬送装置８５について実施例を説明する。
