【0017】
先ず、S1では、刈取り作業中の扱ぎ深さ搬送装置33の株元搬送チェン33aと脱穀フィードチェン19の間における穀稈の詰まりが発生したか否かを、前記穀稈の詰まりセンサ35のON・OFFによって判断し、OFFであれば穀稈の詰まりが発生していないのでS2に進んで通常の扱ぎ深さ制御がなされ、ONであれば穀稈の詰まりが発生しているのでS3に進む。
【0018】
S3では、前記扱ぎ深さ搬送装置33を構成する株元搬送チェン33aと補助搬送チェン33bとが離間する方向、即ち浅扱ぎ方向(図1の下矢印方向)に株元搬送チェン33aを応動させる所要時間に対応した減衰タイマーをスタートさせてS4に進む。
S4では、穀稈の詰まり警報出力としてホーン101の連続音出力がなされてS5に進む。
【0019】
そして、S5では、作業機クラッチの入・切を作業機クラッチスイッチ92のON・OFFによって判断し、ONであればS6に進む。
S6では、E/Gストップソレノイド103に出力してエンジンを停止させ、S7に進む。
【0020】
S7では、上述した株元搬送チェン33aを浅扱ぎ方向に応動させる所要時間に対応した減衰タイマーが作動中か否か、或いは前記株元搬送チェン33aが下方回動リミット位置に達しているか否かを判断し、前記タイマーが作動中か、または株元搬送チェン33aが下方回動リミット位置に達していなければS8に進む。
尚、前記株元搬送チェン33aが下方回動リミット位置に達しているか否かは、前記扱ぎ深さポテンショメータ41やリミットスイッチ等によって検出されるように構成すればよい。
【0021】
そして、S8では、前記扱ぎ深さ搬送装置33を構成する株元搬送チェン33aと補助搬送チェン33bとが離間する方向、即ち浅扱ぎ方向(図1の下矢印方向)に、株元搬送チェン33aを応動(下方回動)させる作動制御が行われる。
【0022】
即ち、上述した扱ぎ深さ搬送装置33の作動制御は、刈取り作業中の扱ぎ深さ搬送装置33の株元搬送チェン33aと脱穀フィードチェン19の間における穀稈の詰まり検知手段である穀稈の詰まりセンサ35によって、刈取り作業中の当該穀稈の詰まりを検知し、その検知信号に基づいて警報出力とエンジン停止出力をなすと共に、前記株元搬送チェン33aと補助搬送チェン33bとが離間する浅扱ぎ方向に株元搬送チェン33aを応動(下方回動)させるものであって、それによって、前記扱ぎ深さ搬送装置33終端と脱穀フィードチェン19始端の受継部周辺に広い作業空間を確保できるので、前記株元搬送チェン33aと脱穀フィードチェン19の間に詰まった穀稈の除去作業が、コンバイン10の運転を停止した安全な状態で行えるようになると共に、確保された広い作業空間によってその作業性も著しく向上する。
【0023】
尚、図4に示すものは、前記扱ぎ深さ搬送装置36の扱ぎ深さ制御を、リレーRY1,RY2,RY3,RY4を用いたロジック回路で構成したもので、扱ぎ深さ制御の方向切替回路と、扱ぎ深さ搬送装置回動モータの作動回路を分割することによって、メンテナンスの容易化と低コスト化を図ったものである。
また、図5に示すものは、前述した図4に示す扱ぎ深さ制御の方向切替回路の自動と手動を分離した構成にしたもので、これによって更にメンテナンスの容易化と低コスト化が図れる。
【0024】
【発明の効果】
以上説明したように本発明は、穀稈の株元側を挟持して脱穀フィードチェン19へ継送する扱ぎ深さ搬送装置33を、穀稈の株元を挟持し搬送始端側中心に上下回動自在な株元搬送チェン33aで構成したコンバイン10において、前記株元搬送チェン33aと脱穀フィードチェン19の間における穀稈の詰まりを検知する詰まり検知手段35を設け、刈取り作業中の前記詰まり検知手段35の穀稈の詰まり検知に基づいて、前記株元搬送チェン33aを浅扱ぎ方向に応動させるように構成したことによって、前記扱ぎ深さ搬送装置33終端と脱穀フィードチェン19始端の受継部周辺に広い作業空間を確保できるので、前記株元搬送チェン33aと脱穀フィードチェン19の間に詰まった穀稈の除去作業の作業性は、確保された広い作業空間によって著しく向上する。

Further, a cutting blade 27 for cutting the root of the grain stalk close to the ground is provided at the rear of the raising device 17 and at the lower front of the transmission shaft cylinder 23, and the grain cut by the cutting blade 27 is provided. The culm is scraped in a substantially upright state by the scraping device 28 (first transport device) and is transferred rearward.
[0010]
The scraping and conveying device 28 has left and right stock transfer chains 29, 30 and a central stock transfer chain (not shown) for pinching and transferring the stock side of the grain stem, while the spike side of the grain stem is The left ear tip transfer tine 31 and the right ear tip transfer tine 32 pinch and are transported backward.
Further, a handling depth transport device 33 (second transport device) that detects the culm length of the harvested culm and automatically adjusts it to an appropriate handling depth is provided behind the scraping transport device 28. ing.
The handling depth transfer device 33 is composed of a stock transfer chain 33a that can vertically rotate about the transfer start end side (centered on the axis X) while holding the stock of the grain culm. Then, the grain culm is laid horizontally and transferred to the threshing feed chain 19 while the grain culm is held sideways by the auxiliary transport chain 33b which clamps the middle part of the grain culm closer to the root of the grain culm.

[0016]
In the control device 85 of the combine 10 having the above-described configuration, the clogging of the grain culm between the stock transport chain 33a of the handling depth transport device 33 and the threshing feed chain 19 is performed by the grain clogging sensor 35 during the mowing operation. The handling depth (operation) control of the handling depth transfer device 33 upon detection will be described below with reference to the flowchart shown in FIG.
[0017]
First, in S1, the clogging sensor 35 of the cereal culm determines whether or not clogging of the cereal culm between the stock transport chain 33a of the handling depth conveying device 33 and the threshing feed chain 19 during the harvesting operation has occurred. Judgment is made by ON / OFF. If it is OFF, the grain culm is not clogged, so the process proceeds to S2, and the normal handling depth control is performed. If it is ON, the grain culm is clogged, and S3. Proceed to.
[0018]
In S3, the stock transfer chain 33a is moved in a direction in which the stock transfer chain 33a and the auxiliary transfer chain 33b constituting the handling depth transfer device 33 are separated, that is, in a shallow handling direction (the downward arrow direction in FIG. 1). The decay timer corresponding to the required time to be activated is started, and the process proceeds to S4.
In S4, a continuous sound output of the horn 101 is output as an alarm output for clogging of the cereal stem, and the process proceeds to S5.
[0019]
In S5, the ON / OFF state of the work machine clutch switch 92 is determined based on the ON / OFF state of the work machine clutch switch.
In S6, the output is output to the E / G stop solenoid 103 to stop the engine, and the process proceeds to S7.
[0020]
In S7, it is determined whether or not the attenuation timer corresponding to the time required to move the stock transfer chain 33a in the shallow handling direction is in operation, or whether the stock transfer chain 33a has reached the lower rotation limit position. If it is determined that the timer is operating or the stock transfer chain 33a has not reached the downward rotation limit position, the process proceeds to S8.
Note that whether or not the stock transfer chain 33a has reached the lower rotation limit position may be configured to be detected by the handling depth potentiometer 41, a limit switch, or the like.
[0021]
In S8, the stock transfer is performed in the direction in which the stock transfer chain 33a and the auxiliary transfer chain 33b constituting the handling depth transfer device 33 are separated, that is, in the shallow handling direction (the downward arrow direction in FIG. 1). An operation control for causing the chain 33a to respond (turn downward) is performed.
[0022]
That is, the above-described operation control of the handling depth transfer device 33 is performed by the grain detection means for detecting clogging of the grain stalk between the stock transfer chain 33a and the threshing feed chain 19 of the handling depth transfer device 33 during the mowing operation. The culm clogging sensor 35 detects clogging of the grain culm during the harvesting operation, and outputs an alarm output and an engine stop output based on the detection signal, and separates the stock transport chain 33a and the auxiliary transport chain 33b. The root conveyor chain 33a is responsively moved (rotated downward) in the shallow handling direction, whereby a large working space is provided around the end of the handling depth transport device 33 and the inheriting portion at the beginning of the threshing feed chain 19. The operation of removing the grain stalk clogged between the stock transfer chain 33a and the threshing feed chain 19 can be performed in a safe state in which the operation of the combine 10 is stopped. Together it becomes so that, also remarkably improved workability by large working space secured.
[0023]
In FIG. 4, the handling depth control of the handling depth transfer device 36 is configured by a logic circuit using relays RY1, RY2, RY3, and RY4. By dividing the direction switching circuit and the operation circuit of the handling depth transfer device rotating motor, maintenance is facilitated and cost is reduced.
FIG. 5 shows a configuration in which the direction switching circuit of the handling depth control shown in FIG. 4 described above is separated from automatic and manual, thereby further facilitating maintenance and reducing costs. .
[0024]
【The invention's effect】
As described above, in the present invention, the handling depth transport device 33 for nipping the stem side of the cereal stem and transferring it to the threshing feed chain 19 is vertically moved to the center of the transport starting end side while nipping the stem of the cereal stem. In the combine 10 constituted by the rotatable stock transport chain 33a, a jam detecting means 35 for detecting jam of the grain stalk between the stock transport chain 33a and the threshing feed chain 19 is provided, and the jam during the harvesting operation is provided. Based on the detection of the clogging of the grain stem by the detecting means 35, the stock transport chain 33a is configured to respond in the shallow handling direction, so that the end of the handling depth transport device 33 and the beginning of the threshing feed chain 19 are started. Since a wide working space can be secured around the inheritance part, the workability of the work of removing the grain stalk clogged between the stock transfer chain 33a and the threshing feed chain 19 is ensured by a wide working space. In significantly greater.
