Is provided with a takeover transfer device 17 for taking over the grain culm.

前記穀稈供給搬送装置16は、前記刈取装置4で刈り取られた穀稈を脱穀装置3の脱穀室(図示省略)の穀稈供給口18から供給し、脱穀されて脱穀室の穀稈排出口(図示省略)より排出するまで搬送するものであるが、刈取装置4で刈り取った穀稈を穀稈供給搬送装置16まで搬送する構成は任意であり、本実施例の構成に限定されず、前記扱深さ調節装置15の終端に穀稈供給搬送装置16の始端部を臨ませてもよく、実施形態の引継搬送装置17を扱深さ調節装置15と穀稈供給搬送装置16との間に介在させているが、この点は要件ではない。 The grain culm supply and transport device 16 supplies the grain culms cut by the reaping device 4 from the grain culm supply port 18 of the grain removal chamber (not shown) of the grain removal device 3, and the grain is culmized and the grain culm discharge port of the grain removal chamber. Although the culm is transported until it is discharged from (not shown), the configuration for transporting the culm cut by the reaping device 4 to the culm supply and transport device 16 is arbitrary and is not limited to the configuration of the present embodiment. The start end of the grain culm supply and transport device 16 may face the end of the handling depth adjusting device 15, and the takeover transport device 17 of the embodiment may be placed between the handling depth adjusting device 15 and the grain culm supply and transport device 16. It is intervening, but this is not a requirement.

前記扱深さ調節装置15の構成も任意であり、穀稈供給搬送装置16に供給する穀稈の挟持位置を変更して扱深さを変更できればよい。本実施形態では、刈取装置4の縦支持フレーム19に扱深さ調節装置15の基部を先端が上下自在となるように取付けて構成している。20は扱深さ調節モーター、21は扱深さ調節モーター20により扱深さ調節装置15を移動させる扱深さ調整手段(扱深さ調節リンク)、22は扱深さ調節装置15の実際の扱深さ位置を検出する扱深さ位置検出部(ポテンショメーター)、23は扱深さセンサSの穂先センサ、24は株元センサであり、穂先が第二穂先センサ24と第一穂先センサ23の中間位置にあるのが、適正な扱深さとなり、第一穂先センサ23と第二穂先センサ24が共にオフのときは浅扱状態となり、第一穂先センサ23と第二穂先センサ24が共にオンのときは深扱状態となる。
なお、図中では、理解を容易にするため、第一穂先センサ23よりも穀稈の株元側に位置する第二穂先センサ24を株元センサと表示しているが、これにより、構成は限定されない。
The configuration of the handling depth adjusting device 15 is also arbitrary, and it is sufficient that the handling depth can be changed by changing the holding position of the grain culm supplied to the grain culm supply / transport device 16. In the present embodiment, the base of the handling depth adjusting device 15 is attached to the vertical support frame 19 of the cutting device 4 so that the tip can be moved up and down. 20 is a handling depth adjusting motor, 21 is a handling depth adjusting means (handling depth adjusting link) for moving the handling depth adjusting device 15 by the handling depth adjusting motor 20, and 22 is an actual handling depth adjusting device 15. The handling depth position detection unit (potentiometer) that detects the handling depth position, 23 is the tip sensor of the handling depth sensor S, 24 is the stock origin sensor, and the tips are the second tip sensor 24 and the first tip sensor 23. The intermediate position is the proper handling depth, and when both the first tip sensor 23 and the second tip sensor 24 are off, the handling state is shallow, and both the first tip sensor 23 and the second tip sensor 24 are on. In the case of, it becomes a deep handling state.
In the figure, for ease of understanding, the second tip sensor 24 located closer to the stock root side of the grain culm than the first tip sensor 23 is displayed as the stock root sensor. Not limited.

本願の扱深さ制御は、穀稈の全長に応じて穂先位置を一定にするように扱深さ調節装置15の先端位置を扱深さ調節モーター20により自動制御するものであり、該扱深さ調節装置15による扱深さ調節は、搬送される穀稈の稈身方向に間隔をおいて配置された扱深さセンサSの第一穂先センサ23と第二穂先センサ24による穀稈の穂先位置の検出結果に基づいて、扱深さ調節装置15を作動させる扱深さ調節モーター20を自動的に駆動して行う構成とし、前記扱深さ調節モーター20に浅扱ぎ側への出力が行われているにも拘わらず、前記扱深さ調節装置15によって調節された扱深さを検出する扱深さ位置検出部22が所定時間にわたって深扱ぎ位置を検出し続けた場合に、前記扱深さセンサSの検出不良状態と判定し、前記扱深さ調節モーター20への出力を自動的に停止する構成とする。 The handling depth control of the present application automatically controls the tip position of the handling depth adjusting device 15 by the handling depth adjusting motor 20 so that the tip position is constant according to the total length of the grain culm. The handling depth adjustment by the pressure adjusting device 15 is performed by the first tip sensor 23 and the second tip sensor 24 of the handling depth sensor S arranged at intervals in the culm direction of the transported grain culm. Based on the position detection result, the handling depth adjustment motor 20 that operates the handling depth adjusting device 15 is automatically driven to perform the operation, and the handling depth adjusting motor 20 outputs an output to the shallow handling side.

すなわち、図7のように、ステップS4で一定時間扱深さ位置検出部22が基準位置より深扱ぎを感知し続けた際に、ステップS5で扱深さ調節モーター20への出力を停止するのである。
なお、出力停止後の制御あるいは作業は任意であり、通常であれば、出力停止をオペレータに報知し、一旦、作業を中断して、扱深さセンサSの異常状態の原因となる穀稈屑や雑草の除去作業を行ってから、作業を再開する。
As a result, due to an erroneous detection of the handling depth sensor S, the operator unexpectedly continues to output to the shallow handling side, resulting in extremely shallow handling, and at the rear portion of the grain culm supply and transport device 16. It is possible to prevent the culm from being pinched and causing poor transportation, resulting in clogging of the straw chain or cutter.
That is, as shown in FIG. 7, when the handling depth position detecting unit 22 continues to detect deep handling from the reference position for a certain period of time in step S4, the output to the handling depth adjusting motor 20 is stopped in step S5. It is.
The control or work after the output is stopped is optional, and normally, the operator is notified of the output stop, the work is temporarily interrupted, and the grain culm that causes an abnormal state of the handling depth sensor S is generated. After removing the weeds and weeds, resume the work.

前記扱深さ調節モーター20に浅扱ぎ側への出力が行われているにも拘わらず、所定時間にわたって前記扱深さ位置検出部22が深扱ぎ位置を検出し続けた場合に、扱深さ調節モーター20へ深扱ぎ側への出力を設定回数出力し、この出力に拘わらず前記扱深さ位置検出部22の検出結果に変化がないときは、前記扱深さ調節モーター20への出力を自動的に停止する構成とする(図8)。
これにより、扱深さセンサSの誤感知により、オペレータが予期せずに浅扱ぎ側に出力を継続してしまって極端な浅扱ぎになり、穀稈供給搬送装置16後方で穀稈の挟持できずに搬送不良を起こし、排藁チェンやカッタで詰まりが発生することを防止できる。
When the handling depth position detecting unit 22 continues to detect the deep handling position for a predetermined time even though the handling depth adjusting motor 20 is outputting to the shallow handling side, it is handled. The output to the deep handling side is output to the depth adjusting motor 20 a set number of times, and if there is no change in the detection result of the handling depth position detecting unit 22 regardless of this output, the handling depth adjusting motor 20 is output. The output of is automatically stopped (Fig. 8).
As a result, due to an erroneous detection of the handling depth sensor S, the operator unexpectedly continues to output to the shallow handling side, resulting in extremely shallow handling, and the grain culm is rearward of the grain culm supply / transport device 16. It is possible to prevent the straw chain and the cutter from being clogged due to poor transportation due to the inability to pinch.

前記扱深さ調節モーター20に浅扱ぎ側への出力が行われているにも拘わらず、所定時間にわたって前記扱深さ位置検出部22が深扱ぎ位置を検出し続けた場合に、前記第一穂先センサ23の検出不良状態と判定し、扱深さ調節モーター20への出力を自動的に停止し、この扱深さ調節モーター20への出力停止状態は、扱深さセンサSよりも穀稈搬送方向上手側に配置された穀稈センサ30が搬送穀稈の存在を検出しなくなった場合に解除される構成とする(図9)。
これにより、第一穂先センサ23の誤感知による穀稈供給搬送装置16後方で穀稈の挟持できずに搬送不良を防止すると共に、刈取作業の1工程が終了し、刈抜けると制御停止を解除する。
When the handling depth position detecting unit 22 continues to detect the deep handling position for a predetermined time even though the handling depth adjusting motor 20 is outputting to the shallow handling side, the above-mentioned It is determined that the detection failure state of the first tip sensor 23 is determined, the output to the handling depth adjustment motor 20 is automatically stopped, and the output stop state to the handling depth adjustment motor 20 is higher than that of the handling depth sensor S. The configuration is such that the grain culm sensor 30 arranged on the upper side in the grain culm transport direction is released when the presence of the transport culm is no longer detected (FIG. 9).
As a result, the grain culm cannot be pinched behind the grain culm supply / transport device 16 due to erroneous detection of the first tip sensor 23, and transport failure is prevented. do.

すなわち、図9のように、ステップS4で一定時間扱深さ位置検出部22が基準位置より深扱ぎを感知し続けた際に、ステップS5で扱深さ調節モーター20への出力を停止後に、ステップ6で穀稈センサ30が切になると、扱深さ調節モーター20への出力停止状態をリセットする。
前記扱深さ調節装置15による扱深さ自動制御では、前記扱深さ調節装置15による扱深さの調節範囲を前記扱深さ調節モータ20への回路内のスイッチ31で切り替え可能な構成とする(図10)。
すなわち、長い作物と標準作物と短い作物と、対象作物に応じて、扱深さ調節モーター20の稼働範囲を回路内のスイッチ31で切り替えて規制する。
これにより、扱深さ調節モーター20の稼働範囲の変更可能にでき、扱深さ制御範囲を広げられる。
このスイッチ31による切替はオペレータが圃場作物を視認して行う。
That is, as shown in FIG. 9, when the handling depth position detecting unit 22 continues to detect deep handling from the reference position for a certain period of time in step S4, after stopping the output to the handling depth adjusting motor 20 in step S5. When the grain sensor 30 is turned off in step 6, the output stop state to the handling depth adjusting motor 20 is reset.
In the handling depth automatic control by the handling depth adjusting device 15, the handling depth adjustment range by the handling depth adjusting device 15 can be switched by a switch 31 in the circuit to the handling depth adjusting motor 20. (Fig. 10).
That is, the operating range of the handling depth adjusting motor 20 is switched and regulated by the switch 31 in the circuit according to the long crop, the standard crop, the short crop, and the target crop.
As a result, the operating range of the handling depth adjusting motor 20 can be changed, and the handling depth control range can be expanded.
The switching by the switch 31 is performed by the operator visually recognizing the field crops.

また、スイッチ31に代えて扱深さ調節モーター20への回路内にジャンパ32を設け、このジャンパ32の接続および切断により扱深さ調節モーター20の稼働範囲を切替える構成とする(図11)。
そのため、本実施形態では、長稈と標準作物とへの扱深さ調節モーター20の稼働範囲の切替えとなり、これにより、長稈作業位置まで稼働可能にし、扱深さ調節モーター20の稼働範囲を長稈まで広げることができる。
例えば、コンバインの出荷時に、扱深さ調節モーター20の稼働範囲の回路内にジャンパ32を設けておき、圃場の作物が長稈作物であった場合、そのまま、扱深さ調節モーター20の稼働範囲を長稈まで広げることができ、長稈の穀稈に対応した扱深さ制御を行え、また、圃場の作物が標準作物の場合、ジャンパ32を外す等により回路を遮断し、標準作物を前提とする扱深さ制御を行える。
Further, instead of the switch 31, a jumper 32 is provided in the circuit to the handling depth adjusting motor 20, and the operating range of the handling depth adjusting motor 20 is switched by connecting and disconnecting the jumper 32 (FIG. 11).
Therefore, in the present embodiment, the operating range of the handling depth adjusting motor 20 is switched between the long culm and the standard crop, whereby the operating range of the handling depth adjusting motor 20 can be changed to the long culm working position. It can be extended to a long culm.
For example, when the combine is shipped, a jumper 32 is provided in the circuit of the operating range of the handling depth adjusting motor 20, and if the crop in the field is a long culm crop, the operating range of the handling depth adjusting motor 20 is as it is. Can be expanded to the long culm, the handling depth can be controlled according to the long culm, and if the crop in the field is a standard crop, the circuit is cut off by removing the jumper 32, etc., and the standard crop is assumed. The handling depth can be controlled.

また、圃場の作物を入れ替える、あるいは、隣接する圃場の作物条件が相違する場合等に前記ジャンパ32により扱深さ調節モーター20の稼働範囲を切替え可能となる。
また、扱深さ調節モーター20の稼働範囲を未刈稈に刈り込んで扱深さ調節の調節作動頻度が減少した状態が一定時間継続した場合、扱深さ調節モーター20の稼働範囲の自動切替えの上下の調節範囲を規制し、あるいは、この扱深さ調節モーター20の稼働範囲を保持する(図12)。
これにより、扱深さ調節モーター20の稼働範囲の変更を自動化できる。
また、扱深さ調節モーター20の稼働範囲を複数の範囲に設定し、この複数の稼働範囲は脱穀クラッチ33の接続後の刈取作業開始時に自動判定し、この判定された稼働範囲から逸脱しない範囲で扱深さ調節モーター20への出力が制御される構成とする(図13)。
Further, when the crops in the field are replaced or the crop conditions in the adjacent fields are different, the operating range of the handling depth adjusting motor 20 can be switched by the jumper 32.
In addition, when the operating range of the handling depth adjustment motor 20 is trimmed to an uncut culm and the operating frequency of the handling depth adjustment adjustment operation continues to decrease for a certain period of time, the operating range of the handling depth adjustment motor 20 is automatically switched. The vertical adjustment range is regulated, or the operating range of the handling depth adjustment motor 20 is maintained (FIG. 12).
As a result, it is possible to automate the change of the operating range of the handling depth adjusting motor 20.
Further, the operating range of the handling depth adjusting motor 20 is set to a plurality of ranges, and the plurality of operating ranges are automatically determined at the start of the cutting operation after the threshing clutch 33 is connected, and the operating range does not deviate from the determined operating range. The output to the handling depth adjustment motor 20 is controlled by the above (FIG. 13).

すなわち、扱深さ調節モーター20の稼働範囲を複数の範囲、例えば、短稈・標準・長稈と設定し、この稼働範囲は脱穀クラッチ33の入り後の刈取作業開始時に自動判定し、逸脱しない範囲で扱深さ調節モーター20の稼働範囲の変更の自動制御する。
この場合、扱深さ調節モータ20の稼働範囲の自動判定を、手動により変更可能な構成とし、穀稈長の設定の手動操作がされると、この稼働範囲にて扱深さ自動制御するように移行する構成とする(図14)。
これにより、操作性を向上させられる。
That is, the operating range of the handling depth adjusting motor 20 is set to a plurality of ranges, for example, short culm, standard, and long culm, and this operating range is automatically determined at the start of cutting work after the threshing clutch 33 is engaged and does not deviate. Automatically controls the change of the operating range of the handling depth adjustment motor 20 within the range.
In this case, the automatic determination of the operating range of the handling depth adjusting motor 20 is configured to be manually changeable, and when the grain length setting is manually operated, the handling depth is automatically controlled in this operating range. The configuration is to be migrated (Fig. 14).
As a result, operability can be improved.

前記脱穀装置3の前板35にギヤケース36を設け、ギヤケース36により脱穀装置3の扱胴(図示省略)に駆動回転を伝動する構成とし(図16)、ギヤケース36の上方を覆うフロントカバー37を設ける(図15)。フロントカバー37は、ギヤケース36の上側部分の所定位置により上方部分を包囲する上側フロントカバー38は側面視後上がりの傾斜面とし、ギヤケース36の所定位置により下方部分を包囲する下側カバー下側フロントカバー39は側面視後下がりの傾斜面とする。
これにより、穀稈供給搬送装置16が前板35の穀稈供給口18から供給搬送する穀稈を、フロントカバー37により円滑に誘導し、ギヤケース36との干渉を抑制し、穀稈供給搬送装置16の搬送を良好にする。
A gear case 36 is provided on the front plate 35 of the threshing device 3, and the gear case 36 is configured to transmit the drive rotation to the handling cylinder (not shown) of the threshing device 3 (FIG. 16), and the front cover 37 covering the upper part of the gear case 36 is provided. Provided (Fig. 15). The front cover 37 surrounds the upper portion of the upper portion of the gear case 36 at a predetermined position. The cover 39 is an inclined surface that descends after side view.
As a result, the grain culm supply and transport device 16 smoothly guides the grain culm to be supplied and transported from the grain culm supply port 18 of the front plate 35 by the front cover 37, suppresses interference with the gear case 36, and suppresses interference with the gear case 36. 16 makes the transport good.

すなわち、下側フロントカバー39の後端部を前板35の穀稈供給口18の上辺の手前まで位置させ、上側フロントカバー38から穀粒や藁屑が流れ落ちる形状としている。
これにより、フロントカバー37に穀粒や藁屑が堆積するのを防止する。
下側フロントカバー39の機体走行方向の左側部分は、穀稈供給口18の上縁より低く配置する(図18)。
また、ギヤケース36の下方には、ギヤケース下側カバー40をフロントカバー37と別体で設ける。
ギヤケース下側カバー40は、その上部形状を正面において、ギヤケース36の下面形状に沿わせて形成し、ギヤケース下側カバー40の下面形状は前板35の穀稈供給口18の上縁形状に沿わせて形成すると共に、側面形状を後下がり傾斜に形成している。
That is, the rear end portion of the lower front cover 39 is positioned to the front of the upper side of the grain culm supply port 18 of the front plate 35, and grains and straw debris flow down from the upper front cover 38.
This prevents grains and straw debris from accumulating on the front cover 37.
The left side portion of the lower front cover 39 in the traveling direction of the machine body is arranged lower than the upper edge of the grain culm supply port 18 (FIG. 18).
Further, below the gear case 36, a gear case lower cover 40 is provided separately from the front cover 37.
The lower cover 40 of the gear case is formed so that the upper shape of the lower cover 40 follows the lower surface shape of the gear case 36 in the front, and the lower surface shape of the lower cover 40 of the gear case follows the upper edge shape of the grain culm supply port 18 of the front plate 35. It is formed so as to be formed, and the side surface shape is formed with a downward slope.

これにより、穀稈供給搬送装置16が前板35の穀稈供給口18から供給搬送する穀稈を、ギヤケース下側カバー40により円滑に誘導し、ギヤケース36との干渉を抑制し、穀稈供給搬送装置16の搬送を良好にする。
前記ギヤケース36は、扱胴軸(図示省略)の周囲を包囲する円形部43と扱胴軸に回転伝達する伝達軸(図示省略)部分を包囲する略直線状の直線部44とを有して形成し、このギヤケース36の下方に設けるギヤケース下側カバー40は円形部43の下方に位置する左カバー部45と直線部44の下方に位置する右カバー部46に分割形成している。
これにより、ギヤケース下側カバー40の製造および取付を容易にし、ギヤケース36の下方を包囲して穀稈との干渉を効果的に抑制する。
As a result, the grain culm supply and transport device 16 smoothly guides the grain culm to be supplied and transported from the grain culm supply port 18 of the front plate 35 by the gear case lower cover 40, suppresses interference with the gear case 36, and supplies the grain culm. Improve the transport of the transport device 16.
The gear case 36 has a circular portion 43 that surrounds the circumference of the handling barrel shaft (not shown) and a substantially linear straight portion 44 that surrounds a transmission shaft (not shown) that rotationally transmits to the handling barrel shaft. The gear case lower cover 40 provided below the gear case 36 is divided into a left cover portion 45 located below the circular portion 43 and a right cover portion 46 located below the straight portion 44.
This facilitates the manufacture and attachment of the gear case lower cover 40 and effectively suppresses interference with the culm by surrounding the lower part of the gear case 36.

すなわち、ギヤケース36の円形部43の下部は直線部44の下面より下方に位置して、円形部43と直線部44との間には段差が生じているが、ギヤケース下側カバー40は前板35の下方を包囲すると共に、穀稈の穂先を案内するガイド作用も奏する。
また、ギヤケース下側カバー40は右カバー部46の右側部分を機体固定部にボルト等により固定し、この右カバー部46に左カバー部45を螺子・ナット等の取付部材47により取付け、左カバー部45の左側部分をギヤケース36の円形部43に取付ける(図17)。
これにより、ギヤケース下側カバー40を取り付けるために特別にステー等を用意するのを不要とし、また、機体固定部およびギヤケース36に対して着脱自在になって、メンテナンスを容易にする。
That is, the lower portion of the circular portion 43 of the gear case 36 is located below the lower surface of the straight portion 44, and a step is formed between the circular portion 43 and the straight portion 44, but the lower cover 40 of the gear case is the front plate. It surrounds the lower part of 35 and also acts as a guide to guide the tips of the culm.
Further, in the gear case lower cover 40, the right side portion of the right cover portion 46 is fixed to the machine body fixing portion with bolts or the like, and the left cover portion 45 is attached to the right cover portion 46 by a mounting member 47 such as a screw or a nut to form the left cover. The left side portion of the portion 45 is attached to the circular portion 43 of the gear case 36 (FIG. 17).
This eliminates the need to prepare a special stay or the like for attaching the gear case lower cover 40, and makes it removable from the machine body fixing portion and the gear case 36, facilitating maintenance.

ギヤケース36の扱胴軸の周囲を包囲する円形部43は側面視後上がりに傾斜させるが、フロントカバー37の下側フロントカバー39は後下がり傾斜に形成する。
これにより、扱胴軸およびこれへの伝動機構を内蔵するためにギヤケース36を側面視後上がりに傾斜させた構成としたギヤケース36を包囲するフロントカバー37を、フロントカバー37の下側フロントカバー39は後下がり傾斜に形成することにより、穀稈との干渉を抑制し、異物の堆積も抑制する。
すなわち、フロントカバー37の下側フロントカバー39は、後方ほど下方に傾斜した形状に形成する。
これにより、穀稈供給搬送装置16による穀稈搬送量が多い場合でも、フロントカバー37は干渉しない。
The circular portion 43 surrounding the circumference of the handling barrel shaft of the gear case 36 is tilted upward when viewed from the side, while the lower front cover 39 of the front cover 37 is formed so as to be tilted backward.
As a result, the front cover 37 surrounding the gear case 36, which is configured such that the gear case 36 is inclined upward after the side view in order to incorporate the handling barrel shaft and the transmission mechanism to the handling barrel shaft, is replaced with the lower front cover 39 of the front cover 37. By forming the cover with a downward slope, it suppresses interference with the grain and also suppresses the accumulation of foreign matter.
That is, the lower front cover 39 of the front cover 37 is formed so as to be inclined downward toward the rear.
As a result, the front cover 37 does not interfere even when the amount of culm transported by the culm supply / transport device 16 is large.

また、ギヤケース下側カバー40は、少なくとも、ギヤケース36の円形部43の左側よりも内側に位置させる(図15、17)。
これにより、穀稈供給口18への穀稈供給搬送装置16による穀稈搬送通路を広く確保でき、脱穀装置3への供給(取込)を円滑にする。
また、後述するギヤケース下側カバー40の前方に設けた弾性部材により構成した垂れカバー50がギヤケース下側カバー40と干渉するのも抑制する。
前記ギヤケース下側カバー40の前方には、弾性部材により構成した垂れカバー垂れカバー50を略鉛直状に設け、垂れカバー50の正面視において穀稈供給搬送装置16側を右上がりに傾斜させ、かつ、右側部分の角部部分を円弧形状に形成する。
Further, the gear case lower cover 40 is positioned at least inside the left side of the circular portion 43 of the gear case 36 (FIGS. 15 and 17).
As a result, a wide passage for transporting the grain culm by the grain culm supply and transport device 16 to the grain culm supply port 18 can be secured, and the supply (take-in) to the threshing device 3 is facilitated.
Further, it is also possible to prevent the hanging cover 50 formed by the elastic member provided in front of the gear case lower cover 40, which will be described later, from interfering with the gear case lower cover 40.
In front of the gear case lower cover 40, a hanging cover hanging cover 50 made of an elastic member is provided substantially vertically, and the grain culm supply / transporting device 16 side is tilted upward to the right when the hanging cover 50 is viewed from the front. , The corner of the right side is formed into an arc shape.

これにより、穀稈供給口18からの被処理物の吹き出しを垂れカバー50により防止する共に、穀稈の搬送を円滑にでき、しかも、穀稈との接触による垂れカバー50の損傷も抑制する。
また、ギヤケース下側カバー40は穀稈の株元側の穀稈供給口18に設けないこととし、フロントカバー37に取付けた垂れカバー50が後方にまくれ上がっても、ギヤケース下側カバー40に干渉しない位置関係とする。
これにより、垂れカバー50は穀稈供給口18からの被処理物の吹き出しを防止しつつ、穀稈供給口18の穂先側での穀稈の取込の際のギヤケース下側カバー40との干渉を防止する。
As a result, the blowout of the object to be processed from the grain culm supply port 18 is prevented by the hanging cover 50, the transportation of the grain culm can be smoothed, and the damage of the hanging cover 50 due to the contact with the grain culm is also suppressed.
Further, the gear case lower cover 40 is not provided at the grain culm supply port 18 on the stock culm side of the culm, and even if the hanging cover 50 attached to the front cover 37 is rolled up rearward, it interferes with the gear case lower cover 40. The positional relationship is not set.
As a result, the hanging cover 50 prevents the object to be processed from being blown out from the grain culm supply port 18, and interferes with the gear case lower cover 40 when the culm is taken in on the tip side of the grain culm supply port 18. To prevent.

図19は、脱穀装置3の他の実施形態を示し、脱穀装置3扱室(図示省略)の上方を包囲する上方カバー55の開放機構を作動させるカバー開放駆動モーター56を前記ギヤケース36の上方に設け、このカバー開放駆動モーター56の上方を包囲するカバー57を設け、カバー57にはカバー開放駆動モーター56を露出させる窓部58を設けた構成とする。
これにより、上方カバー55の開放機構をカバー57により包囲できると共に、カバー開放駆動モーター56とカバー57との干渉を防止する。
また、カバー57は前下がり傾斜のため、上方カバー55の開放機構に藁屑等が付着・堆積を防止できる。
FIG. 19 shows another embodiment of the threshing device 3 in which a cover opening drive motor 56 for operating the opening mechanism of the upper cover 55 surrounding the upper part of the threshing device 3 handling chamber (not shown) is placed above the gear case 36. A cover 57 is provided so as to surround the upper part of the cover open drive motor 56, and the cover 57 is provided with a window portion 58 for exposing the cover open drive motor 56.
As a result, the opening mechanism of the upper cover 55 can be surrounded by the cover 57, and interference between the cover opening drive motor 56 and the cover 57 is prevented.
Further, since the cover 57 is inclined forward, it is possible to prevent straw dust and the like from adhering and accumulating on the opening mechanism of the upper cover 55.

なお、カバー開放駆動モーター56の一部を露出させる前記窓部58により、カバー57の取付の際の位置決めとして利用すると、カバー57の装着を容易にする。
また、フロントカバー37は、合成樹脂等の可撓性の部材により形成すると、上方カバー55の開放機構との干渉を防止できて、好適である。
また、脱穀装置3の前板35と上方カバー55との合わせ目の上方にカバー57の一部を臨ませる。
これにより、上方カバー55を上方開放させた際に、上方カバー55の開放機構に藁屑等が付着・堆積を防止できると共に、上方カバー55の開放機構の作動を円滑にさせる。
The window portion 58 that exposes a part of the cover open drive motor 56 facilitates the attachment of the cover 57 when used for positioning when the cover 57 is attached.
Further, if the front cover 37 is formed of a flexible member such as a synthetic resin, it is preferable because it can prevent interference with the opening mechanism of the upper cover 55.
Further, a part of the cover 57 is made to face above the joint between the front plate 35 of the threshing device 3 and the upper cover 55.
As a result, when the upper cover 55 is opened upward, straw dust and the like can be prevented from adhering to and accumulating on the opening mechanism of the upper cover 55, and the opening mechanism of the upper cover 55 is smoothly operated.

また、カバー57の上方に、カバー57より上方に露出するカバー開放駆動モーター56の部位を包囲するモータ包囲カバー(図示省略)を別途設けてもよい。
脱穀装置3の扱胴60を円筒状に形成し、扱胴60の外周に扱歯61を設けたものにおいて、各扱歯61は扱胴60の外周に螺旋状に複数列配置し、かつ、螺旋状に配置した扱歯61群の配列途中に低い扱歯61を設ける構成とする(図20)。
これにより、通常作業時は高い扱歯61が主に作用するため、脱穀負荷を低減でき、高流量時は低い扱歯61も作用してさらなるこなし作用を行うことで脱穀ロスを防止する。
この場合、扱歯61は、扱胴60の後半部に設置密度を高めて配置すると共に、増加する扱歯61は低い扱歯61とする。
Further, a motor surrounding cover (not shown) may be separately provided above the cover 57 to surround the portion of the cover opening drive motor 56 exposed above the cover 57.
In the case where the handling cylinder 60 of the grain removing device 3 is formed in a cylindrical shape and the handling teeth 61 are provided on the outer circumference of the handling cylinder 60, each of the handling teeth 61 is spirally arranged in a plurality of rows on the outer circumference of the handling cylinder 60, and A low handling tooth 61 is provided in the middle of the arrangement of the spirally arranged handling teeth 61 group (FIG. 20).
As a result, since the high handling teeth 61 mainly act during normal work, the threshing load can be reduced, and during high flow rates, the low handling teeth 61 also act to perform further handling action, thereby preventing threshing loss.
In this case, the handling teeth 61 are arranged in the latter half of the handling cylinder 60 with a high installation density, and the increasing handling teeth 61 are low handling teeth 61.

これにより、設置密度を高めた扱歯61により搬送穀稈中の刺さり粒を減少させることができると共に、増加させた扱歯61を低い扱歯61としているので、脱穀負荷の増加を抑制する。
上記構成のコンバインにおいて、グレンタンク5内に穀粒が所定量溜まると、刈取脱穀作業を一旦中止し、機体を停止させて穀粒排出作業を行うが、このとき、走行装置2を停止させる所謂駐車ブレーキを作動させるブレーキ操作を行なわないと、ブザーあるいはランプ等により報知する構成とする。
これにより、機体が超微速で動いているのを、オペレータが看過するのを防止でき、排出作業の安全性を向上させられる。
また、この報知の際には、穀粒排出操作を不能にする構成とする。
これにより、報知を無視した排出作業にも対応しうる。
As a result, the number of stabbed grains in the transported grain culm can be reduced by the handling teeth 61 having an increased installation density, and since the increased handling teeth 61 are set to the low handling teeth 61, an increase in the threshing load is suppressed.
In the combine having the above configuration, when a predetermined amount of grains are accumulated in the grain tank 5, the cutting and threshing work is temporarily stopped, the machine is stopped to perform the grain discharging work, but at this time, the traveling device 2 is stopped. If the brake operation that activates the parking brake is not performed, a buzzer, a lamp, or the like is used to notify the vehicle.
As a result, it is possible to prevent the operator from overlooking that the airframe is moving at an ultra-low speed, and it is possible to improve the safety of the discharging work.
In addition, at the time of this notification, the configuration is such that the grain discharge operation is disabled.
As a result, it is possible to deal with the discharge work ignoring the notification.

また、穀粒排出作業をする際に、車速センサ(図示省略)が車速を感知すると、穀粒排出クラッチ操作を不能にする構成し、さらに、排出操作が行なわれたときには、エンジンを停止させてもよい。
また、穀粒排出作業をする際に、駐車ブレーキを掛けないで、報知手段により報知すると共に、排出操作が行なわれたときには、エンジンを停止させてもよい。
上記構成のコンバインにおいて、機体所定位置に設けた、GPS情報を受信して機***置を測位する測位機構(機***置情報取得手段)と、この測位機構による測位情報に基づいてグレンタンク5内の穀粒排出穀粒排出先の位置情報取得手段とを設け、排出場所まで自動誘導する構成とする。
これにより、穀粒排出作業性を向上させられる。
Further, when the vehicle speed sensor (not shown) detects the vehicle speed during the grain discharge work, the grain discharge clutch operation is disabled, and when the grain discharge operation is performed, the engine is stopped. May be good.
Further, when the grain discharging work is performed, the parking brake may not be applied, and the notification means may be used to notify the grain, and the engine may be stopped when the discharging operation is performed.

(実施形態の作用)
本発明は上記構成であり、機体を走行させて、刈取装置4により圃場の穀稈を刈り取り、脱穀装置3により脱穀作業を行う。
刈取装置4の刈刃12にて刈り取られた穀稈は、搬送装置により穀稈供給搬送装置16に搬送供給され、穀稈供給搬送装置16が脱穀装置3の扱室に供給搬送して脱穀されるが、刈取装置4の扱深さ調節装置15により穀稈供給搬送装置16へ受け渡す位置を調節して扱深さ調節されて受け渡される。
この扱深さ調節装置15による扱深さ調節は、第一穂先センサ23と第二穂先センサ24のオン/オフによって、扱深さ調整手段21を作動させる扱深さ調節モーター20を駆動し、扱深さ位置検出部22が扱深さ調整手段21による実際の扱深さ位置を検出して制御部にフィードバックして行う。
(Action of Embodiment)
The present invention has the above-mentioned configuration, and the machine is driven to mow the culms in the field by the cutting device 4, and the threshing operation is performed by the threshing device 3.
The grain culm cut by the cutting blade 12 of the reaping device 4 is transported and supplied to the grain culm supply and transport device 16 by the transport device, and the grain culm supply and transport device 16 is supplied and transported to the handling room of the grain removal device 3 for degraining. However, the handling depth adjusting device 15 of the cutting device 4 adjusts the position of delivery to the grain culm supply and transport device 16, and the handling depth is adjusted before delivery.
The handling depth adjustment by the handling depth adjusting device 15 drives the handling depth adjusting motor 20 that operates the handling depth adjusting means 21 by turning on / off the first tip sensor 23 and the second tip sensor 24. The handling depth position detecting unit 22 detects the actual handling depth position by the handling depth adjusting means 21 and feeds it back to the control unit.

この扱深さ制御は、穀稈の全長に応じて穂先位置を一定にするように扱深さ調節装置15を自動制御するものであり、扱深さ調節装置15による扱深さ調節は、搬送される穀稈の稈身方向に間隔をおいて配置された扱深さセンサSの第一穂先センサ23と第二穂先センサ24による穀稈の穂先位置の検出結果に基づいて、扱深さ調節装置15を作動させる扱深さ調節モーター20を自動的に駆動して行う構成とし、前記扱深さ調節モーター20に浅扱ぎ側への出力が行われているにも拘わらず、前記扱深さ調節装置15によって調節された扱深さを検出する扱深さ位置検出部22が所定時間にわたって深扱ぎ位置を検出し続けた場合に、前記扱深さセンサSの検出不良状態と判定し、前記扱深さ調節モーター20への出力を自動的に停止する構成としているので、扱深さセンサSの誤感知により、オペレータが予期せずに浅扱ぎ側への出力を継続してしまって極端な浅扱ぎになり、穀稈供給搬送装置16の後方部分で穀稈の挟持ができずに搬送不良を起こし、排藁チェンやカッタで詰まりが発生することを防止できる。 This handling depth control automatically controls the handling depth adjusting device 15 so that the tip position is constant according to the total length of the grain culm, and the handling depth adjustment by the handling depth adjusting device 15 is conveyed. The handling depth is adjusted based on the detection result of the tip position of the grain by the first tip sensor 23 and the second tip sensor 24 of the handling depth sensor S arranged at intervals in the culm direction of the culm to be processed. The handling depth adjustment motor 20 for operating the device 15 is automatically driven, and the handling depth is the handling depth even though the handling depth adjusting motor 20 outputs to the shallow handling side. When the handling depth position detecting unit 22 that detects the handling depth adjusted by the culm adjusting device 15 continues to detect the deep handling position for a predetermined time, it is determined that the handling depth sensor S has a detection failure state. Since the output to the handling depth adjustment motor 20 is automatically stopped, the operator unexpectedly continues to output to the shallow handling side due to an erroneous detection of the handling depth sensor S. This makes it extremely shallow, and it is possible to prevent the grain culm from being pinched at the rear portion of the grain culm supply / transport device 16 and causing a transport failure, resulting in clogging of the straw culm chain or cutter.

すなわち、図7のように、ステップS4で一定時間扱深さ位置検出部22が基準位置より深扱ぎを感知し続けた際に、ステップS5で扱深さ調節モーター20への出力を停止するのである。
なお、出力停止後の制御あるいは作業は任意であり、通常であれば、出力停止をオペレータに報知し、一旦、作業を中断して、扱深さセンサSの異常状態の原因となる穀稈屑や雑草の除去作業を行ってから、作業を再開する。
That is, as shown in FIG. 7, when the handling depth position detecting unit 22 continues to detect deep handling from the reference position for a certain period of time in step S4, the output to the handling depth adjusting motor 20 is stopped in step S5. It is.
The control or work after the output is stopped is optional, and normally, the operator is notified of the output stop, the work is temporarily interrupted, and the grain culm that causes an abnormal state of the handling depth sensor S is generated. After removing the weeds and weeds, resume the work.

前記扱深さ調節モーター20に浅扱ぎ側への出力が行われているにも拘わらず、所定時間にわたって前記扱深さ位置検出部22が深扱ぎ位置を検出し続けた場合に、扱深さ調節モーター20へ深扱ぎ側への出力を設定回数出力し、この出力に拘わらず前記扱深さ位置検出部22の検出結果に変化がないときは、前記扱深さ調節モーター20への出力を自動的に停止する構成としているので、扱深さセンサSの誤感知により、オペレータが予期せずに浅扱ぎ側に出力を継続してしまって極端な浅扱ぎになり、穀稈供給搬送装置16後方で穀稈の挟持できずに搬送不良を起こし、排藁チェンやカッタで詰まりが発生することを防止できる。 When the handling depth position detecting unit 22 continues to detect the deep handling position for a predetermined time even though the handling depth adjusting motor 20 is outputting to the shallow handling side, it is handled. The output to the deep handling side is output to the depth adjustment motor 20 a set number of times, and if there is no change in the detection result of the handling depth position detection unit 22 regardless of this output, the handling depth adjustment motor 20 is output. Because it is configured to automatically stop the output of, the operator unexpectedly continues the output to the shallow handling side due to the false detection of the handling depth sensor S, resulting in extremely shallow handling, and the grain. It is possible to prevent the culm from being caught behind the culm supply / transport device 16 and causing a transport failure, resulting in clogging of the straw discharge chain or cutter.

前記扱深さ調節モーター20に浅扱ぎ側への出力が行われているにも拘わらず、所定時間にわたって前記扱深さ位置検出部22が深扱ぎ位置を検出し続けた場合に、前記第一穂先センサ23の検出不良状態と判定し、扱深さ調節モーター20への出力を自動的に停止し、この扱深さ調節モーター20への出力停止状態は、扱深さセンサSよりも穀稈搬送方向上手側に配置された穀稈センサ30が搬送穀稈の存在を検出しなくなった場合に解除される構成としているので、第一穂先センサ23の誤感知による穀稈供給搬送装置16後方で穀稈の挟持できずに搬送不良を防止すると共に、刈取作業の1工程が終了し、刈抜けると制御停止を解除する。 When the handling depth position detecting unit 22 continues to detect the deep handling position for a predetermined time even though the handling depth adjusting motor 20 is outputting to the shallow handling side, the above-mentioned It is determined that the detection failure state of the first tip sensor 23 is determined, the output to the handling depth adjustment motor 20 is automatically stopped, and the output stop state to the handling depth adjustment motor 20 is higher than that of the handling depth sensor S. Since the grain culm sensor 30 arranged on the upper side in the grain culm transport direction is configured to be released when the presence of the transport culm is no longer detected, the grain culm supply and transport device 16 due to an erroneous detection of the first tip sensor 23. The grain culm cannot be pinched in the rear to prevent poor transportation, and when one step of the cutting work is completed and the cutting is completed, the control stop is released.

すなわち、図9のように、ステップS4で一定時間扱深さ位置検出部22が基準位置より深扱ぎを感知し続けた際に、ステップS5で扱深さ調節モーター20への出力を停止後に、ステップ6で穀稈センサ30が切になると、扱深さ調節モーター20への出力停止状態をリセットする。
前記扱深さ調節装置15による扱深さ自動制御では、前記扱深さ調節装置15による扱深さの調節範囲を前記扱深さ調節モータ20への回路内のスイッチ31で切り替え可能な構成としているので、長い作物と標準作物と短い作物と、対象作物に応じて、扱深さ調節モーター20の稼働範囲を回路内のスイッチ31で切り替えて規制する。
これにより、扱深さ調節モーター20の稼働範囲の変更可能にでき、扱深さ制御範囲を広げられる。
That is, as shown in FIG. 9, when the handling depth position detecting unit 22 continues to detect deep handling from the reference position for a certain period of time in step S4, after stopping the output to the handling depth adjusting motor 20 in step S5. When the grain sensor 30 is turned off in step 6, the output stop state to the handling depth adjusting motor 20 is reset.
In the handling depth automatic control by the handling depth adjusting device 15, the handling depth adjustment range by the handling depth adjusting device 15 can be switched by a switch 31 in the circuit to the handling depth adjusting motor 20. Therefore, the operating range of the handling depth adjusting motor 20 is switched and regulated by the switch 31 in the circuit according to the long crop, the standard crop, the short crop, and the target crop.
As a result, the operating range of the handling depth adjusting motor 20 can be changed, and the handling depth control range can be expanded.

また、スイッチ31に代えて扱深さ調節モーター20への回路内にジャンパ32を設け、このジャンパ32の接続および切断により扱深さ調節モーター20の稼働範囲を切替える構成としているので、長稈と標準作物とへの扱深さ調節モーター20の稼働範囲の切替えとなり、これにより、長稈作業位置まで稼働可能にし、扱深さ調節モーター20の稼働範囲を長稈まで広げることができる。
例えば、コンバインの出荷時に、扱深さ調節モーター20の稼働範囲の回路内にジャンパ32を設けておき、コンバインの販売地域の圃場の作物が長稈作物であった場合、そのまま、扱深さ調節モーター20の稼働範囲を長稈まで広げることができ、長稈の穀稈に対応した扱深さ制御を行え、また、圃場の作物が標準作物の場合、ジャンパ32を外す等により回路を遮断し、標準作物を前提とする扱深さ制御を行える。
Further, instead of the switch 31, a jumper 32 is provided in the circuit to the handling depth adjusting motor 20, and the operating range of the handling depth adjusting motor 20 is switched by connecting and disconnecting the jumper 32. The operating range of the handling depth adjusting motor 20 for standard crops is switched, whereby it is possible to operate up to the long culm working position, and the operating range of the handling depth adjusting motor 20 can be extended to the long culm.
For example, when the combine is shipped, a jumper 32 is provided in the circuit of the operating range of the handling depth adjustment motor 20, and if the crop in the field of the combine sales area is a long culm crop, the handling depth is adjusted as it is. The operating range of the motor 20 can be extended to the long culm, the handling depth can be controlled according to the long culm, and when the crop in the field is a standard crop, the circuit is cut off by removing the jumper 32 or the like. , The handling depth can be controlled on the premise of standard crops.

また、圃場の作物を入れ替える、あるいは、隣接する圃場の作物条件が相違する場合等に前記ジャンパ32により扱深さ調節モーター20の稼働範囲を切替え可能となる。
また、扱深さ調節モーター20の稼働範囲を未刈稈に刈り込んで扱深さ調節の調節作動頻度が減少した状態が一定時間継続した場合、扱深さ調節モーター20の稼働範囲の自動切替えの上下の調節範囲を規制し、あるいは、この扱深さ調節モーター20の稼働範囲を保持するので、扱深さ調節モーター20の稼働範囲の変更を自動化できる。
Further, when the crops in the field are replaced or the crop conditions in the adjacent fields are different, the operating range of the handling depth adjusting motor 20 can be switched by the jumper 32.
In addition, when the operating range of the handling depth adjustment motor 20 is trimmed to an uncut culm and the operating frequency of the handling depth adjustment adjustment operation continues to decrease for a certain period of time, the operating range of the handling depth adjustment motor 20 is automatically switched. Since the upper and lower adjustment ranges are regulated or the operating range of the handling depth adjusting motor 20 is maintained, the change of the operating range of the handling depth adjusting motor 20 can be automated.

また、扱深さ調節モーター20の稼働範囲を複数の範囲に設定し、この複数の稼働範囲は脱穀クラッチ33の接続後の刈取作業開始時に自動判定し、この判定された稼働範囲から逸脱しない範囲で扱深さ調節モーター20への出力が制御される構成とするので、扱深さ調節モーター20の稼働範囲を複数の範囲、例えば、短稈・標準・長稈と設定し、この稼働範囲は脱穀クラッチ33の入り後の刈取作業開始時に自動判定し、逸脱しない範囲で扱深さ調節モーター20の稼働範囲の変更の自動制御する。
この場合、扱深さ調節モータ20の稼働範囲の自動判定を、手動により変更可能な構成とし、穀稈長の設定の手動操作がされると、この稼働範囲にて扱深さ自動制御するように移行する構成とすると、操作性を向上させられる。
Further, the operating range of the handling depth adjusting motor 20 is set to a plurality of ranges, and the plurality of operating ranges are automatically determined at the start of the cutting operation after the threshing clutch 33 is connected, and the operating range does not deviate from the determined operating range. Since the output to the handling depth adjustment motor 20 is controlled by, the operating range of the handling depth adjusting motor 20 is set to a plurality of ranges, for example, short clutch, standard clutch, and long clutch, and this operating range is set. It is automatically determined at the start of the cutting operation after the threshing clutch 33 is engaged, and the change in the operating range of the handling depth adjusting motor 20 is automatically controlled within a range that does not deviate.
In this case, the automatic determination of the operating range of the handling depth adjusting motor 20 is configured to be manually changeable, and when the grain length setting is manually operated, the handling depth is automatically controlled in this operating range. The operability can be improved if the configuration is to be migrated.
