Description

本発明は、刈取穀稈を脱穀部に向けて支持搬送し且つ車体の走行変速に合わせて搬送速度が同調変速される搬送装置と、搬送装置における刈取穀稈の稈長方向での支持位置を変更して前記脱穀部での扱深さを調節する扱深さ調節手段と、前記扱深さ調節手段による扱深さ調節箇所よりも搬送下手側の穂先位置検出箇所において前記搬送装置により搬送される刈取穀稈の穂先位置が適正範囲に位置するか否かを検出する穂先位置検出手段と、前記穂先位置検出手段にて検出される刈取穀稈の穂先位置が前記適正範囲に位置するように前記扱深さ調節手段の作動を制御する制御手段とを備えたコンバインの扱深さ制御装置に関するものである。   The present invention provides a conveying device that supports and conveys the harvested cereal toward the threshing portion and the transmission speed is synchronized with the shift of the vehicle body, and changes the support position in the cocoon length direction of the harvested cereal in the conveying device. Then, the handling depth adjusting means for adjusting the handling depth in the threshing portion, and the tip position detection location on the lower side of the delivery than the handling depth adjustment location by the handling depth adjustment means is conveyed by the conveying device. The tip position detecting means for detecting whether or not the tip position of the harvested grain pod is in an appropriate range, and the tip position of the harvested grain pod detected by the tip position detecting means is in the appropriate range. The present invention relates to a combine depth control device including control means for controlling the operation of a handle depth adjusting means.
かかるコンバインの扱深さ制御において、従来では、穂先位置検出手段にて刈取穀稈の穂先位置が適正範囲から外れたことが検出されると、刈取穀稈の穂先位置を適正範囲に位置させる方向に向けて扱深さ調節手段を作動させる扱深さ調節処理を行い、刈取穀稈の穂先位置が適正範囲に位置するまで作動させるように扱深さ調節手段の作動を制御するように構成されていた(例えば、特許文献1参照。)。
特開2002−204612号公報
In such a combine depth control, conventionally, when the tip position detecting means detects that the tip position of the harvested cereal rice is out of the appropriate range, the direction of positioning the tip position of the harvested cereal rice cake in the appropriate range. It is configured to control the operation of the treatment depth adjusting means so as to operate until the tip position of the harvested cereal rice bran is in an appropriate range. (For example, refer to Patent Document 1).
JP 2002-204612 A
しかし、上記特許文献1は、穂先位置検出箇所が扱深さ調節箇所から搬送下手側に離れて位置しており、刈取穀稈が扱深さ検出箇所から穂先位置検出箇所まで搬送されるには搬送時間が必要であるため、扱深さ調節箇所にて扱深さ調節処理が行われたすぐ後に穂先位置検出箇所における穂先位置検出手段の検出情報に基づいて次の扱深さ調節処理が行われると、先の扱深さ調節処理にて支持位置が設定調節量変更された刈取穀稈が穂先位置検出箇所まで搬送される前に、この刈取穀稈より搬送上手側の支持位置が設定調整量変更されていない刈取穀稈の穂先位置に基づいて次の扱深さ調節処理が行われてしまうので、扱深さ調節手段を不必要に動かすことによりハンチングが生じるものであった。   However, in Patent Document 1 described above, the tip position detection location is located away from the handling depth adjustment location on the lower conveyance side, and the harvested cereal is transported from the handling depth detection location to the tip location detection location. Since the conveyance time is required, the next treatment depth adjustment process is performed based on the detection information of the tip position detection means at the tip position detection location immediately after the handling depth adjustment processing is performed at the handling depth adjustment location. The support position on the upper transfer side of the harvested cereal meal is adjusted before the harvested cereal meal whose support position has been changed by the adjustment processing amount in the previous handling depth adjustment process is delivered to the point detection position. Since the next handling depth adjustment process will be performed based on the tip position of the harvested grain culm that has not been changed in quantity, hunting is caused by unnecessarily moving the handling depth adjustment means.
そこで、先の扱深さ調節処理を行った後、予め定められた一定の設定待ち時間が経過するまで扱深さ調節手段の作動を停止させる停止処理を行ってから次の扱深さ調節処理を穂先位置検出手段の検出結果に基づいて行うように構成することも考えられるが、この構成であると、停止処理における設定待ち時間が予め定められた一定の設定待ち時間であるのに対して、搬送装置の搬送速度が車体の走行速度に合わせて同調変速するように構成されており、刈取穀稈が扱深さ調節箇所から穂先位置検出箇所に搬送されるまでに必要な時間は車体の走行速度が速くなると短くなり遅くなると長くなるものであるため、設定待ち時間を高速走行時に合わせて短く設定すると、低速走行時では先の扱深さ調節処理にて支持位置が設定調節量変更された刈取穀稈が穂先位置検出箇所まで搬送される前に停止処理が終了してしまい、先の扱深さ調節処理にて支持位置を設定調整量変更させた刈取穀稈が穂先位置検出箇所に到達する前に後の扱深さ調節処理を行うことによりハンチングが生じ、また、設定待ち時間を低速走行時に合わせて長く設定すると、高速走行時では扱深さ調節処理にて支持位置が設定調節量変更された刈取穀稈が穂先位置検出箇所まで搬送された後も必要以上に停止処理が継続されて扱深さ調節を迅速に行うことができないものであった。   Therefore, after performing the previous treatment depth adjustment process, after performing a stop process to stop the operation of the treatment depth adjustment means until a predetermined fixed waiting time elapses, the next treatment depth adjustment process Although it is conceivable that the configuration is performed based on the detection result of the tip position detection means, in this configuration, the set waiting time in the stop process is a predetermined fixed waiting time. The conveying speed of the conveying device is configured to synchronize with the traveling speed of the vehicle body, and the time required for the harvested cereal to be conveyed from the depth adjustment position to the tip position detection position is If the set waiting time is set to a short time for high speed driving, the support position is changed by the previous processing depth adjustment process during low speed driving. Cutting The stop process ends before the cereals are transported to the tip position detection location, and the harvested cereals whose support position has been set and adjusted by the previous handling depth adjustment processing reach the tip location detection location. Hunting occurs due to the previous and subsequent treatment depth adjustment processing, and if the set waiting time is set to be long for low speed running, the support position is changed by the treatment depth adjustment processing during high speed running. Even after the harvested cereal grains were transported to the tip position detection point, the stop process was continued more than necessary, and the handling depth could not be adjusted quickly.
本発明は、上記実状に鑑みて為されたものであって、その目的は、車体の走行変速に合わせて搬送装置の搬送速度が同調変速されても、扱深さ制御を正確且つ迅速に行うことができるコンバインの扱深さ制御手段を提供する点にある。   The present invention has been made in view of the above circumstances, and an object of the present invention is to accurately and promptly control the depth of handling even when the transport speed of the transport device is synchronized with the traveling speed of the vehicle body. It is in the point of providing the handling depth control means of the combine which can be performed.
本願発明のコンバインの扱深さ制御装置は、刈取穀稈を脱穀部に向けて支持搬送し且つ車体の走行変速に合わせて搬送速度が同調変速される搬送装置と、その搬送装置における刈取穀稈の稈長方向での支持位置を変更して前記脱穀部での扱深さを調節する扱深さ調節手段と、その扱深さ調節手段による扱深さ調節箇所よりも搬送下手側の穂先位置検出箇所において前記搬送装置により搬送される刈取穀稈の穂先位置が適正範囲に位置するか否かを検出する穂先位置検出手段と、前記穂先位置検出手段にて検出される刈取穀稈の穂先位置が前記適正範囲に位置するように前記扱深さ調節手段の作動を制御する制御手段とを備えたコンバインの扱深さ制御装置であって、
第1特徴構成は、前記制御手段が、前記穂先位置検出手段にて刈取穀稈の穂先位置が前記適正範囲から外れたことが検出されると、刈取穀稈の穂先位置を前記適正範囲に位置させる方向に向けて前記扱深さ調節手段を設定調整量で作動させる扱深さ調節処理を行い、その扱深さ調節処理が行われた後、前記搬送装置の搬送速度を検出する搬送速度検出手段の検出情報に基づいて前記搬送装置の搬送速度が速くなると短くなりかつ前記搬送装置の搬送速度が遅くなると長くなるように前記搬送装置の搬送速度に応じて設定された刈取穀稈が扱深さ調節箇所から穂先位置検出箇所に搬送されるまでの設定待ち時間が経過するまで、前記穂先位置検出手段にて刈取穀稈の穂先位置が前記適正範囲から外れたことが検出されても前記扱深さ調節手段の浅扱き側及び深扱き側への作動を停止させる停止処理を行うように構成されている点を特徴とする。
The combined depth control device of the present invention includes a conveying device that supports and conveys the harvested cereal toward the threshing portion, and the conveyance speed is synchronized with the traveling speed of the vehicle body, and the harvested cereal cocoon in the conveying device. Depth adjustment means for adjusting the treatment depth in the threshing portion by changing the support position in the cocoon length direction, and the tip position detection on the lower side of the conveyance from the treatment depth adjustment position by the treatment depth adjustment means The tip position detection means for detecting whether or not the tip position of the harvested cereal cocoons conveyed by the transport device at a location is within an appropriate range, and the tip position of the chopped grain pods detected by the tip position detecting means A combine depth control device comprising a control means for controlling the operation of the handle depth adjusting means so as to be located in the appropriate range,
In the first characteristic configuration, when the control means detects that the tip position of the harvested grain pod is out of the appropriate range by the tip position detecting means, the tip position of the harvested grain pod is located in the appropriate range. performs threshing depth adjusting process be operated at setting adjustment amount of the threshing depth adjusting means in a direction to its after threshing depth adjusting process is performed, the conveying speed detection for detecting the conveying speed of the conveying device Based on the detection information of the means, the harvested cereal meal set according to the transport speed of the transport device is shortened when the transport speed of the transport device becomes faster and becomes longer when the transport speed of the transport device becomes slower. Even if it is detected by the tip position detecting means that the tip position of the harvested cereal is out of the appropriate range until the set waiting time until it is transported from the adjustment point to the tip position detecting portion elapses, the handling is performed. of depth adjustment means Stops the operation of the ironing side and depth ironing side, characterized in that it is configured to perform stop processing.
すなわち、扱深さ調節処理を行った後の停止処理が、搬送装置の搬送速度を検出する搬送速度検出手段の検出情報に基づいて搬送装置の搬送速度が速くなると短くなりかつ搬送装置の搬送速度が遅くなると長くなるように搬送装置の搬送速度に応じて設定された扱深さ調節箇所から穂先位置検出箇所に搬送される刈取穀稈が扱深さ調節箇所から穂先位置検出箇所に搬送されるまでの設定待ち時間が経過するまで、穂先位置検出手段にて刈取穀稈の穂先位置が適正範囲から外れたことが検出されても扱深さ調節手段の作動を停止させるように構成されているので、搬送装置の搬送速度に拘わらず、先の扱深さ調節処理で支持位置を設定調整量変更された刈取穀稈が穂先位置検出箇所に搬送されてその刈取穀稈の穂先位置が適正範囲から外れたことが穂先位置検出手段にて検出されると次の扱深さ調節処理が行われることとなり、先の扱深さ調節処理で支持位置を設定調整量変更させた刈取穀稈が穂先位置検出箇所に到達する前に後の扱深さ調節処理を行うことによるハンチングが生じることがなくなり、また、次の扱深さ調節処理が、搬送装置の搬送速度に拘わらず、先の扱深さ調節処理にて支持位置を設定調整量変更させた刈取穀稈が穂先位置検出箇所に搬送されるのと同時に又は略同時に次の扱深さ調節処理を行うことができるので扱深さ調節を迅速に行うことができ、もって、車体の走行変速に合わせて搬送装置の搬送速度が同調変速されても、扱深さ制御を正確且つ迅速に行うことができるコンバインの扱深さ制御装置を提供することができるに至った。 In other words, the stop process after the handling depth adjustment process is shortened as the transport speed of the transport apparatus increases based on the detection information of the transport speed detecting means for detecting the transport speed of the transport apparatus, and the transport speed of the transport apparatus Harvested cereals that are transported from the handling depth adjustment point set according to the transport speed of the transport device to the tip position detection point so as to become longer as the speed becomes slower are transported from the handling depth adjustment point to the tip position detection point Until the set waiting time elapses, the tip position detecting means is configured to stop the operation of the handling depth adjusting means even if it is detected that the tip position of the harvested cereal is out of the proper range. Therefore, regardless of the transport speed of the transport device, the cutting position that has been set and adjusted in the support position in the previous handling depth adjustment process is transferred to the tip position detection point, and the tip position of the cutting position is within the proper range. Octopus Is detected by the tip position detection means, the next handling depth adjustment processing is performed, and the harvested cereal rice cake whose setting adjustment amount has been changed by the previous handling depth adjustment processing is changed to the tip position detection location. Hunting due to the subsequent handling depth adjustment process before it reaches will no longer occur, and the next handling depth adjustment process will be the same as the previous handling depth adjustment process regardless of the transport speed of the transport device. Since the next handling depth adjustment processing can be performed at the same time or almost simultaneously with the cutting cereal grains whose support position has been changed by the set adjustment amount is transferred to the tip position detection point, the handling depth adjustment should be performed quickly. Therefore, it is possible to provide a combined handling depth control device capable of accurately and quickly performing the handling depth control even when the conveyance speed of the conveyance device is synchronously shifted in accordance with the travel shift of the vehicle body. It came to.
第2特徴構成は、上記第1特徴構成に加えて、前記穂先位置検出手段が、穀稈の存否を検出する穂先側検出手段及び株元側検出手段を刈取穀稈の稈長方向に設定間隔を隔てる状態で並置して構成され、前記設定調整量が、前記設定間隔の半分に相当する量である点を特徴とする。   In the second feature configuration, in addition to the first feature configuration, the tip position detection means sets a tip interval detection means and a strain origin side detection means for detecting the presence / absence of a grain pod in a cocoon length direction of the harvested culm. The setting adjustment amount is an amount corresponding to half of the setting interval.
すなわち、穂先位置検出手段にて刈取穀稈の穂先位置が適正範囲から外れたことが検出されると、刈取穀稈の穂先位置を適正範囲に位置させる方向に向けて扱深さ調節手段を設定間隔の半分に相当する量で作動させる扱深さ調節処理を行うことによって、適正範囲から外れていた刈取穀稈の穂先位置が適正範囲の中央付近に変位することとなり、刈取穀稈の穂先位置が適正範囲から外れにくくすることができる。   That is, when it is detected by the tip position detection means that the tip position of the harvested grain culm is out of the proper range, the handling depth adjustment means is set in a direction to position the tip position of the harvested grain culm in the proper range. By performing the depth-of-handling adjustment process that operates at an amount equivalent to half of the interval, the tip position of the harvested cereal cocoon that was out of the proper range will be displaced near the center of the proper range, and the tip position of the chopped cereal cocoon Can be made difficult to deviate from the proper range.
第3特徴構成は、上記第1又は第2特徴構成に加えて、前記搬送速度検出手段が、前記搬送装置に検出作用して搬送速度を検出するように構成されている点を特徴とする。 The third feature configuration is characterized in that, in addition to the first or second feature configuration, the transport speed detecting means is configured to detect the transport speed by detecting the transport device.
すなわち、搬送速度検出手段が、前記搬送装置に検出作用して搬送速度を検出するように構成されているので、車軸等から搬送装置の搬送速度を間接的に検出するものと比べて正確に検出することができ、扱深さ制御を正確に行うことができる。   That is, since the conveyance speed detection means is configured to detect the conveyance speed by detecting the conveyance apparatus, it can be detected more accurately than an apparatus that indirectly detects the conveyance speed of the conveyance apparatus from the axle or the like. It is possible to perform the depth control accurately.
以下、本発明にかかるコンバインの扱深さ制御装置の実施の形態を図面に基づいて説明する。
図1に示すように、コンバインは、左右一対のクローラ走行装置1、刈取穀稈を脱穀処理する脱穀装置(脱穀部に相当)2、操縦部3等を備えた車体の前部に、稲や麦等の植立穀稈を刈り取って脱穀装置2に刈取穀稈として供給する刈取部4を横軸芯P周りで昇降自在に連結して構成されている。
DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a combined depth control device according to the present invention will be described below with reference to the drawings.
As shown in FIG. 1, the combine is provided with a pair of left and right crawler traveling devices 1, a threshing device (corresponding to a threshing portion) 2 for threshing the harvested cereal rice cake, a front portion of a vehicle body equipped with a control portion 3, etc. The cutting part 4 which cuts off planted cereals such as wheat and supplies it to the threshing device 2 as the harvested cereals is connected to the horizontal axis P so as to be movable up and down.
前記刈取部4は、植立穀稈を引き起こす引起し装置5、引き起こされた植立穀稈の株元を切断して刈取穀稈とする刈刃6、刈取穀稈を寄せ集めて後方へ搬送する補助搬送装置7、補助搬送装置7から受け取った刈取穀稈を搬送終端部において横倒れ姿勢に変更して脱穀装置2の脱穀フィードチェーン8に搬送する縦搬送装置(搬送装置に相当)9等を備え、昇降用シリンダ10の駆動により横軸芯P周りに昇降揺動するよう構成されている。   The mowing unit 4 raises a raising device 5 that causes a planted culm, a cutting blade 6 that cuts the root of the planted culm and makes it a harvested culm, and collects the harvested cereal and transports it backward. Auxiliary conveying device 7 to be cut, a vertical conveying device (corresponding to a conveying device) 9 for transferring the harvested cereal rice cake received from the auxiliary conveying device 7 to the threshing feed chain 8 of the threshing device 2 by changing it to a sideways posture at the conveying terminal end, etc. And is configured to swing up and down around the horizontal axis P by driving the lifting cylinder 10.
次に、コンバインの動力伝動系について説明する。図2に示すように、エンジンEの駆動力がベルト伝動装置を介して無段式の車速変速装置21に伝えられ、この車速変速装置21の変速後の出力がミッションケース22を介して、クローラ走行装置1を回転させるべく伝動されている。又、エンジンEの駆動力は、脱穀クラッチ24を介して脱穀装置2にも伝動されている。そして、車速変速装置21の変速後の出力は、ミッションケース22とワンウェイクラッチ23とを介して刈取部4にも伝動され、車速変速装置21の変速後の動力が刈取部4に伝動されることにより、刈取部4の駆動速度が車体の走行速度に同調して変速するよう構成されている。つまり、刈取部4における縦搬送装置9が車体の走行変速に合わせて同調変速されるように構成されており、車体の走行速度が速くなると縦搬送装置9の搬送速度も速くなり、車体の走行速度が遅くなると縦搬送装置9の搬送速度も遅くなる。   Next, the power transmission system of the combine will be described. As shown in FIG. 2, the driving force of the engine E is transmitted to the continuously variable vehicle speed transmission 21 via the belt transmission, and the output after the speed change of the vehicle speed transmission 21 is transmitted to the crawler via the mission case 22. It is transmitted to rotate the traveling device 1. The driving force of the engine E is also transmitted to the threshing device 2 via the threshing clutch 24. The output after shifting of the vehicle speed transmission 21 is transmitted to the cutting unit 4 via the transmission case 22 and the one-way clutch 23, and the power after shifting of the vehicle speed transmission 21 is transmitted to the cutting unit 4. Thus, the driving speed of the cutting unit 4 is configured to shift in synchronization with the traveling speed of the vehicle body. That is, the vertical conveying device 9 in the cutting unit 4 is configured to be synchronously shifted in accordance with the traveling shift of the vehicle body. When the traveling speed of the vehicle body increases, the conveying speed of the vertical conveying device 9 also increases, and the vehicle travels. When the speed decreases, the conveying speed of the vertical conveying device 9 also decreases.
前記縦搬送装置9は、穀稈の株元側を挟持搬送する株元搬送装置9a、穀稈の穂先側を係止搬送する穂先搬送装置9b及び穂先案内板9cから成り、刈取部4の揺動軸芯Pと同一軸芯周りで揺動自在に支持してあり、ギア式減速機構付き電動モータにて構成された扱深さモータ(扱深さ調節手段に相当)M1にて縦搬送装置9を揺動調節することによって、補助搬送装置7から縦搬送装置9に受け渡す際の刈取穀稈の稈長方向での支持位置を変更して脱穀装置2での扱深さを調節するように構成されている。つまり、前記扱深さモータM1によって縦搬送装置9が揺動調節されることにより、縦搬送装置9の補助搬送装置7からの刈取穀稈の受け取り支持位置が稈長方向に変更され、脱穀装置2の扱室における扱深さが変更調節できるよう構成されている。   The vertical transport device 9 includes a stock transport device 9a for holding and transporting the stock side of the grain straw, a tip transport device 9b for locking and transporting the stock tip side of the grain straw, and a tip guide plate 9c. A vertical conveying device is supported by a handling depth motor (corresponding to a handling depth adjusting means) M1, which is supported by an electric motor with a gear-type reduction mechanism and is swingably supported around the same axis as the dynamic axis P. By adjusting the swing of 9, the support position in the cocoon length direction of the harvested cereal rice cake at the time of delivery from the auxiliary transport device 7 to the vertical transport device 9 is changed to adjust the handling depth in the threshing device 2. It is configured. That is, when the vertical conveying device 9 is swing-adjusted by the handling depth motor M1, the receiving support position of the harvested cereal mash from the auxiliary conveying device 7 of the vertical conveying device 9 is changed in the cocoon length direction, and the threshing device 2 The treatment depth in the treatment room can be changed and adjusted.
そして、前記扱深さモータM1による扱深さ調節箇所(補助搬送装置7から縦搬送装置9への刈取穀稈の受け渡し箇所)よりも穀稈搬送経路の下手側の検出箇所において、縦搬送装置9により搬送される刈取穀稈の穂先位置が適正範囲に位置するか否かを検出する穂先位置検出手段Sが備えられている。この穂先位置検出手段Sは、穀稈の存否を検出する穂先側検出センサ(穂先側検出手段に相当)S1及び株元側検出センサ(株元側検出手段に相当)S2を刈取穀稈の稈長方向に所定間隔を隔てる状態で並置して構成されている。尚、前記穂先側検出センサS1及び株元側検出センサS2のそれぞれは穀稈が接触すると揺動してオン作動するスイッチ式に構成されるものであり、穀稈が接触してオン作動したときに穀稈有りを検出し、穀稈が接触していないオフ状態のときに穀稈無しを検出するように構成されている。   And in the detection location on the lower side of the grain culm conveyance path from the treatment depth adjustment location (the location where the harvested cereals are transferred from the auxiliary conveyance device 7 to the vertical conveyance device 9) by the treatment depth motor M1, the vertical conveyance device 9 is provided with tip position detecting means S for detecting whether the tip position of the harvested grain culm conveyed by 9 is within an appropriate range. The tip position detection means S is a head-side detection sensor (corresponding to the tip-side detection means) S1 for detecting the presence or absence of grain pods and a stock-source-side detection sensor (corresponding to the strain-source-side detection means) S2. They are arranged side by side at a predetermined interval in the direction. The tip side detection sensor S1 and the stock side detection sensor S2 are each configured to be a switch type that swings and activates when the cereal comes into contact, and when the cereal comes into contact and is turned on. The presence of corn straw is detected, and the absence of corn straw is detected when the corn straw is in an off state where it is not in contact.
次に、制御手段100について説明する。図3に示すように、マイクロコンピュータを利用した制御手段100に、縦搬送装置9における搬送上手側端部に設けられて穀稈の存否を検出する株元センサ14や前記縦搬送装置9における株元搬送装置9aの駆動スプロケットに検出作用して縦搬送装置9の搬送速度を検出する搬送速度センサ(搬送速度検出手段に相当)19、前記穂先側センサS1及び株元側センサS2の各検出情報が入力されている。一方、制御手段100からは、扱深さモータM1に対する駆動信号が出力されている。
そして、制御手段100は、前記株元センサ14がオン状態であり、前記脱穀クラッチ24が伝動状態である場合に、穂先位置検出手段Sにて検出される刈取穀稈の穂先位置が前記適正範囲に位置するように扱深さモータM1の作動を制御する扱深さ制御を行うように構成されている。
Next, the control means 100 will be described. As shown in FIG. 3, in the control means 100 using a microcomputer, the stock sensor 14 provided at the upper end of the transport in the vertical transport device 9 to detect the presence or absence of cereals or the stock in the vertical transport device 9 Information detected by a transport speed sensor (corresponding to a transport speed detecting means) 19 for detecting the transport speed of the vertical transport apparatus 9 by detecting the action on the drive sprocket of the original transport apparatus 9a, the tip side sensor S1, and the stock side sensor S2 Is entered. On the other hand, the control means 100 outputs a drive signal for the handling depth motor M1.
The control means 100 determines that the tip position of the harvested grain pod is detected by the tip position detection means S when the stock sensor 14 is on and the threshing clutch 24 is in the transmission range. It is comprised so that the handling depth control which controls the action | operation of the handling depth motor M1 may be performed so that it may be located in.
次に、扱深さ制御について説明する。扱深さ制御は、前記穂先位置検出手段Sにて検出される刈取穀稈の穂先位置が、図4(イ)に示すような前記株元側センサS2がオン状態で且つ穂先側センサS1がオフ状態となる前記適正範囲に位置するように扱深さモータM1の作動を制御し、刈取穀稈の稈長にかかわらず扱深さが常に適切な状態に調節されるように構成されている。   Next, handling depth control will be described. In the depth control, the tip position of the harvested grain pod detected by the tip position detecting means S is such that the stock side sensor S2 as shown in FIG. The operation of the handling depth motor M1 is controlled so as to be located in the appropriate range in the off state, and the handling depth is always adjusted to an appropriate state regardless of the length of the harvested culm.
そして、穂先位置検出手段Sにて刈取穀稈の穂先位置が適正範囲から外れたことが検出されると、刈取穀稈の穂先位置を適正範囲に位置させる方向に向けて扱深さモータM1を設定調整量で作動させる扱深さ調節処理を行い、その後、縦搬送装置9の搬送速度を検出する搬送速度センサ19の検出情報に基づいて、刈取穀稈が扱深さ調節箇所から穂先位置検出箇所に搬送される刈取穀稈が扱深さ調節箇所から穂先位置検出箇所に搬送されるまで扱深さモータM1の作動を停止させる停止処理を行うことを繰り返す形態で、扱深さモータM1の作動を制御するように構成されている。   Then, when it is detected by the tip position detection means S that the tip position of the harvested grain culm is out of the proper range, the handling depth motor M1 is moved toward the direction in which the tip position of the harvested grain culm is located in the proper range. A handling depth adjustment process that operates with the set adjustment amount is performed, and then the cutting cereal culm detects the tip position from the handling depth adjustment location based on the detection information of the conveyance speed sensor 19 that detects the conveyance speed of the vertical conveyance device 9. In the form of repeatedly performing the stop process of stopping the operation of the handling depth motor M1 until the harvested cereal meal conveyed to the location is conveyed from the handling depth adjustment location to the tip position detection location, It is configured to control operation.
扱深さ制御について図5のフローチャートに基づいて詳述すると、穂先位置検出手段Sにて刈取穀稈の穂先位置が適正範囲に位置するか否かを検出し、穂先位置検出手段Sにて刈取穀稈の穂先位置が適正範囲から外れたことが検出されると、扱深さモータM1を設定調整量で作動させて刈取穀稈の穂先位置を適正範囲に位置させる方向に向けて変位させるように扱深さ調節処理が行われる。つまり、図4(ロ)に示すような穂先側センサS1並びに株元側センサS2がともにオン状態となり、穂先位置検出手段Sにて刈取穀稈の穂先位置が適正範囲から深扱ぎ側に外れたことが検出されると、扱深さモータM1が設定調整量で作動されて縦搬送装置9が緩傾斜側に揺動調節され、刈取穀稈の稈長方向での支持位置が設定調整量穂先側に調節される扱深さ調節処理が行われ、縦搬送装置9における刈取穀稈の支持位置が浅扱ぎ側へ設定調整量調節される。また、図4(ハ)に示すような穂先側センサS1並びに株元側センサS2がともにオフ状態となり、穂先位置検出手段Sにて刈取穀稈の穂先位置が適正範囲から浅扱ぎ側に外れたことが検出されると、扱深さモータM1が設定調整量で作動されて縦搬送装置9が緩傾斜側に揺動調節され、刈取穀稈の稈長方向での支持位置が設定調整量株元側に調節される扱深さ調節処理が行われ、縦搬送装置9における刈取穀稈の支持位置を深扱ぎ側へ設定調整量調節される。前記設定調整量は、前記穂先側センサS1と前記株元側センサS2とが隔たる所定間隔の半分に相当する量であり、扱深さ調節処理では、刈取穀稈の支持位置を設定調整量調節するために扱深さモータM1が設定時間(例えば200msec)作動する。   The handling depth control will be described in detail with reference to the flowchart of FIG. 5. The tip position detecting means S detects whether the tip position of the harvested cereal is within an appropriate range, and the tip position detecting means S cuts the cutting edge. When it is detected that the tip position of the grain pod is out of the proper range, the handling depth motor M1 is operated with the set adjustment amount so as to displace the tip position of the harvested grain pod in the proper range. The handling depth adjustment process is performed. That is, both the tip side sensor S1 and the stock side sensor S2 as shown in FIG. 4 (b) are turned on, and the tip position of the harvested cereal pods deviates from the proper range to the deep handling side by the tip position detecting means S. When it is detected that the handling depth motor M1 is actuated by the set adjustment amount, the vertical conveying device 9 is adjusted to swing to the gentle inclination side, and the support position in the cocoon length direction of the harvested cereal is set as the set adjustment amount tip. The handling depth adjustment process adjusted to the side is performed, and the support position of the harvested cereal rice cake in the vertical conveying device 9 is adjusted to the shallow handling side by the set adjustment amount. Further, both the tip side sensor S1 and the stock source side sensor S2 as shown in FIG. 4 (c) are turned off, and the tip position of the harvested cereal is moved from the proper range to the shallow handle side by the tip position detecting means S. When it is detected that the handling depth motor M1 is actuated with the set adjustment amount, the vertical conveying device 9 is swing-adjusted to the gentle inclination side, and the support position in the cocoon length direction of the harvested cereal culm is set to The handling depth adjustment process adjusted to the original side is performed, and the set adjustment amount is adjusted to the deep handling side with respect to the support position of the harvested cereal culm in the vertical conveying device 9. The set adjustment amount is an amount corresponding to half of a predetermined interval that the tip side sensor S1 and the stock side sensor S2 are separated from each other. In order to adjust, the handling depth motor M1 operates for a set time (for example, 200 msec).
そして、扱深さ調節処理が行われた後、刈取穀稈が扱深さ調節箇所から穂先位置検出箇所に搬送されるまでの設定待ち時間が経過するまで扱深さモータM1の作動を停止させる停止処理を行う。つまり、扱深さ調節処理が行われてから設定待ち時間が経過するまでは、穂先位置検出手段Sにて、図4(ロ)に示すように刈取穀稈の穂先位置が適正範囲から深扱ぎ側に外れた状態や、図4(ハ)に示すような刈取穀稈の穂先位置が適正範囲から浅扱ぎ側に外れた状態となって、穂先位置検出箇所における搬送装置により搬送される刈取穀稈の穂先位置が適正範囲に位置しないことが検出されたとしても、扱深さモータM1の停止状態を維持させ、刈取穀稈の稈長方向での支持位置を変更させない。そして、扱深さ調節処理が行われてから設定待ち時間が経過した後に、穂先位置検出箇所における搬送装置により搬送される刈取穀稈の穂先位置が適正範囲に位置しないことが検出されると、扱深さ調節処理が行われる。尚、設定待ち時間が経過したか否かに拘らず、穂先側センサS1がオン状態となり株元側センサS2がオフ状態となると、穂先位置検出手段Sが故障したとして扱深さ制御を停止させて警報が出力される。   Then, after the handling depth adjustment process is performed, the operation of the handling depth motor M1 is stopped until a set waiting time elapses until the harvested cereal is conveyed from the handling depth adjustment location to the tip position detection location. Perform stop processing. That is, until the set waiting time elapses after the treatment depth adjustment process is performed, the tip position detection means S handles the tip position of the harvested cereal from the appropriate range as shown in FIG. In a state where the tip of the harvested cereal is removed from the proper range, the state where the tip of the harvested cereal is removed from the appropriate range to the shallow handling side is transported by the transport device at the tip position detection point. Even if it is detected that the tip position of the harvested grain culm is not in the proper range, the stopped state of the handling depth motor M1 is maintained, and the support position in the cocoon length direction of the harvested grain culm is not changed. Then, after the set waiting time has elapsed since the handling depth adjustment process has been performed, when it is detected that the tip position of the harvested grain culm that is transported by the transport device in the tip position detection location is not in the proper range, A handling depth adjustment process is performed. Regardless of whether or not the set waiting time has elapsed, when the tip side sensor S1 is turned on and the stock source side sensor S2 is turned off, the tip depth detection means S is stopped and the handling depth control is stopped. Alarm is output.
前記設定待ち時間は、縦搬送装置9の搬送速度に応じて変更されるものであり、前記搬送速度センサ19の検出情報と制御装置100の扱深さ調節箇所から穂先位置検出箇所までの距離情報とから、刈取穀稈が扱深さ調節箇所から穂先位置検出箇所に搬送されるまでの時間が求められ、この時間が設定待ち時間に設定される。従って、設定待ち時間は、縦搬送装置9の搬送速度が速くなると短くなり、縦搬送装置9の搬送速度が遅くなると長くなるものであり、例えば、刈取穀稈が扱深さ調節箇所から穂先位置検出箇所に搬送されるまでの時間が300msecであれば、設定待ち時間として扱深さモータM1の作動を300msec停止させ、刈取穀稈が扱深さ調節箇所から穂先位置検出箇所に搬送されるまでの時間が400msecであれば、設定待ち時間として扱深さモータM1の作動を400msec停止させる。   The set waiting time is changed according to the conveyance speed of the vertical conveyance device 9, and the detection information of the conveyance speed sensor 19 and the distance information from the handling depth adjustment location of the control device 100 to the tip position detection location. From this, the time until the harvested cereal meal is conveyed from the treatment depth adjustment location to the tip position detection location is determined, and this time is set as the set waiting time. Accordingly, the set waiting time becomes shorter when the conveying speed of the vertical conveying device 9 becomes faster and becomes longer when the conveying speed of the vertical conveying device 9 becomes slower. If the time until it is conveyed to the detection location is 300 msec, the operation of the handling depth motor M1 is stopped for 300 msec as a set waiting time until the harvested cereal is conveyed from the handling depth adjustment location to the tip position detection location Is 400 msec, the operation of the motor depth motor M1 is stopped for 400 msec as the set waiting time.
