本発明は、コンバインに関する。 The present invention relates to a combine.

コンバインの脱穀穀粒選別装置は、扱胴で脱穀した脱穀処理物を載せて前後に揺動しながら藁屑等を後方へ送って終端から排出する揺動選別棚とこの揺動選別棚から落下する穀粒等に含まれる細かい藁屑等を唐箕からの選別風で後方へ吹き飛ばして選別する風選装置とで構成している。
そして、揺動選別棚上に供給される脱穀処理物の量によって唐箕からの選別風を案内する風割の向きを変えて揺動選別棚の下方に送られる選別風を強くしたり弱くしたり自動的に制御するようにした技術が下記特許文献１に記載されている。 Combined threshing grain sorting device is equipped with a swinging sorting shelf that puts the threshing processed product threshed with a handling cylinder and swings back and forth while sending swarf etc. backward and discharging from the end and falling from this swinging sorting shelf It is composed of a wind selection device that blows away fine swarf etc. contained in the grain to be squeezed back with a sorting wind from Karatsu.

コンバインを停止させて手刈り穀稈を脱穀装置に供給する手扱ぎ脱穀の場合には一時的に多くの脱穀処理物が揺動選別棚へ供給されてすぐに減少する状態を繰り返す。この脱穀処理物の一時的な増加時に風割の自動制御を行って揺動選別棚への選別風が強くしたり弱くしたりすると、脱穀処理物が増加後すぐに減少することで自動制御の遅れによって、少ない脱穀処理物が強い選別風によって藁屑と共に穀粒の一部を排出口から機外へ排出して収穫ロスを発生させる。
そこで、本発明は、脱穀処理物の多少によって風割の案内選別風量を自動制御するコンバインの脱穀穀粒選別装置において、コンバインへの手刈り穀稈の供給時などの機体停止状態において、一時的な脱穀処理物の増減による穀粒の収穫ロスを無くすることを課題とする。 In the case of the manual threshing in which the combine is stopped and the hand-harvested cereal meal is supplied to the threshing device, a large number of threshing products are temporarily supplied to the oscillating sorting shelf and the state immediately decreases. If the wind speed is automatically controlled during the temporary increase of the threshing product and the sorting wind to the swing sorting shelf is made stronger or weaker, the threshing product will decrease immediately after the increase and the automatic control will be reduced. Due to the delay, a small amount of processed threshing material causes a harvesting loss by discharging a part of the grain from the outlet to the outside of the machine together with the sawdust by strong sorting wind.
Therefore, the present invention provides a threshing grain sorting device for a combine that automatically controls the guide sorting air volume of the wind split according to the amount of threshing processed material. It is an object of the present invention to eliminate grain loss due to increase or decrease of processed threshing products.

以下、本発明の実施形態を図面に示す実施例を参照しながら説明する。
コンバインの脱穀装置１５は、扱胴１６を前後方向の扱胴軸１７によって脱穀室１８に軸装し、この脱穀室１８の一側に沿う穀稈移送口に穀稈を挾持して移送するフィ−ドチェン１９を設け、車体前方の刈取装置２０で刈取られて搬送装置２１で搬送される穀稈の供給を受けて脱穀する。２２は前側の供給口、２３は後側の排稈口、２４は脱穀室１８の下側に沿って張設する脱穀網である。
脱穀室１８の後側には排稈室２５と排塵室２６とが形成され、この排稈室２５には前記フィ−ドチェン１９によって搬送される脱穀済排稈を受けて後方の機外へ排出する排稈装置２７を設け、排塵室２６には吸引排塵機２８を設けている。揺動選別棚１は、このような脱穀室１８から排塵室２６に亘る間の下方に設けられて、脱穀機枠に対して前後に揺動駆動されるように支架されている。又、この揺動選別棚１の下側に唐箕４及び主・副選別風路５，７、更には一番受樋１４や二番受樋２９等を配置する。
３０は操縦台、３１は操縦席、３２は脱穀装置１５で脱穀された穀粒を取出収容するグレンタンク、３３は排稈を細断する排稈カッタ−である。Ｅはエンジンである。
操縦席３１の側方には、変速レバー６２を設けており、この変速レバー６２の前後傾動操作によって、走行装置の駆動速度を無段階に変速する。
前記揺動選別棚１は、脱穀網２４の下側に送り突子を形成した移送板３４を配置し、この移送板３４の終端から後方に亘って傾斜板３５を一定間隔にして鎧板状に配置したチャフシ−ブ２を設け、該移送板３４上から移送される脱穀物や排稈口２３から排出されるわら屑等を受けて揺動移送しながら主として穀粒を漏下選別する。このチャフシ−ブ２の終端部には排塵室２６の下側においてわら屑を揺動移送しながら後方へ排出するストロ−ラック３６を配置する。３はグレンシ−ブで、前記チャフシ−ブ２から漏下される選別物を受けて穀粒を漏下選別するものである。
唐箕４は移送板３４の下部に設けられて、後側の主選別風路５へ向けて主送風口６を開口し、又、副選別風路７へ向けて副送風口８を開口し、ファン３７の回転によってこれらの送風口６，８から圧風を吹き出し、主選別風路５や副選別風路７から揺動選別棚１の選別間隙部等を経て、前記吸引排塵機２８による吸引風として流すものである。
主送風口６と副送風口８との間には送風方向変更手段である風割９を設け、この風割９の後端面１１は後下りの傾斜面として、上板３８は若干後方へ突出するように延長し、下板３９はこの上板３８よりも後方へ延長させ、前記グレンシ−ブ３前端部の案内板１３をこの後端面１１の後側に対向させる。この案内板１３は該上板３８の後方延長面よりも適宜間隔下位にあって、揺動選別棚１が前後に揺動しても、これら上板３８の上端部や後端面１１に接触しないように構成している。
この上板３８とこの上側に対向する案内板４０との間に副送風口８が形成され、これら上板３８と案内板４０との間隔は、唐箕４側が広く、副選別風路７側が狭くなるように順次絞られて、送風が速くなるように形成されている。副選別風路７は、揺動選別棚１と一体の前記案内板１３と移送板３４の終端部下面に設けられる案内板４１との間に、順次狭くなるように絞って形成されて、これらによって案内される選別風が移送板３４の先端部とこの後側に対向するチャフシ−ブ２の前端部の傾斜板３５との間の間隔部４２を通して揺動選別棚１上方へ吹き抜けるように構成している。又、この傾斜板３５の下端縁と案内板１３の上端縁との間には、副選別風路７からグレンシ−ブ３上面に開通する間隔部４３が形成され、該間隔部４３から漏下される選別物をグレンシ−ブ３上へ案内させるように構成している。
このようにして、副送風口８から吹き出される選別風は、風速が高められて副選別風路７を間隔部４２へ案内されるため、この間隔部４２を上方へ吹き上げられる風圧によって移送板３４上をこの間隔部４２上へ送り出される脱穀物がここで浮上されて、わら屑等がチャフシ−ブ２の後部へ吹き飛ばされ易くなり、穀粒の漏下が行われ易く、揺動移送選別作用が速やかに円滑に行われる。
また、風割９は、枢支軸５０で上下に回動可能に支持され、移送板３４の上に設ける処理物層厚センサ５１が多くの脱穀処理物を検出すると上方へ回動してファン３７からの選別風を多く取り込んで副選別風路７に送られる風量を増加させ、少しの脱穀処理物を検出すると下方へ回動して副選別風路７に送られる風量を減少させるように自動制御される。
図４に風割９の上下回動を制御する自動制御のブロック図を示している。
風割制御コントローラ６１に入力する信号は、脱穀装置１５の入・切を検出する脱穀クラッチセンサ５２のクラッチ信号、自動制御スイッチ５４のオン・オフ信号、風割角度センサ５５の風割９の角度、処理物層厚センサ５１の検出する脱穀処理物の供給量検出信号、風割角度設定ダイヤル５７の設定角度信号、駐車ペダルセンサ５８からの駐車ペダル踏み込み信号、変速レバー６２の操作位置を検出する主変速センサ５９からの中立位置信号、車速センサ６０からの走行速度信号であり、風割駆動モータ５３へ風割９の角度制御信号を出力する。
風割制御コントローラ６１は、自動制御スイッチ５４をオンすると処理物層厚センサ５１からの脱穀処理物の量によって風割駆動モータ５３の自動制御を行う。処理物層厚センサ５１による検出量が多い場合は、副選別風路７を流れる選別風の風量を増加させるように風割９を上方へ回動し、処理物層厚センサ５１による検出量が少ない場合は、副選別風路７を流れる選別風の風量を減少させるように風割９を下方へ回動する方向へ風割駆動モータ５３を駆動するのであるが、脱穀クラッチセンサ５２がオンで、且つ、走行停止検出手段Ｄが機体の走行停止を検出した状態、すなわち手扱ぎ可能状態を判断すると、風割９を下方へ回動して副選別風路７を流れる選別風の風量を減少させるように風割駆動モータ５３を制御する。
走行停止検出手段（Ｄ）は駐車ペダルセンサ５８が駐車ペダルの踏み込みを検出するか、主変速センサ５９が変速の中立を検出するか、または車速センサ６０が速度ゼロを検出することによって機体の走行停止状態を判断する。
主送風口６には第二風割１０及び風導板４４を形成し、この風導板４４の前端は、この上側の風割９の前端４５や下側の第二風割１０の前端４６よりも後位置にあって、この風割９の下板３９による唐箕４側からの風受面積を広くして、風割９と導風板４４との間の送風力が大きくなるように構成して、主選別風路５におけるグレンシ−ブ３に沿う風当りを良くするように構成している。風導板４４の後端部も上風割９の後端面１１の下端縁よりも前位に設定して、後端面１２上に流下する穀粒の邪魔をしない構成としている。
又、これら各段の風割９の後端面１１と第二風割１０の後端面１２は、共に後下りの傾斜として、階段状に形成され、最下段の後端面１２は一番受樋１４上に臨ませている。
各傾斜板３５は揺動選別棚１の側枠部に枢支されて、この傾斜角が急になるほど前後間隔が広くなり、脱穀選別物の漏下も行われ易くなる。
なお、エンジンＥから生じる排気ガス中の微粒子を集めるフィルタを再生させるために排気管の温度を上昇させて微粒子を焼却する排気浄化装置を搭載したコンバインでは、フィルタの再生時に、脱穀装置１５の扱ぎ深さ自動制御で深扱ぎに設定して駆動負荷を増大させたり、前記風割９を上方へ回動させて駆動負荷を増大させて、フィルタを昇温させる。
また、エンジンＥの回転数を自動制御するエンジン回転制御において、オーガ排出クラッチを切り刈取脱穀クラッチを切り走行主変速レバーを中立にする条件で、例えアクセルレバーで回転数を指示していてもエンジン回転数を指示回転数よりも数％だけ低下させる制御を行って、省燃費運転をする。この場合に、前記条件が成立する前の実回転数がアクセルレバー指示回転数より低ければ増速をしない。なお、駐車ブレーキを入りから切にした場合やアクセルレバーを所定以上動かした場合或いはエンジン自動制御スイッチを切り再度入れた場合には、エンジン回転数をアクセルレバー指示回転数に戻す。また、エンジン回転数を指示回転数よりも低下させている場合にはエンジン自動制御スイッチの表示ランプを点滅させる。この表示ランプの点滅はエンジン回転数を指示回転数に戻すと連続点灯に変更する。
また、刈取装置を降下して所定距離走行した場合或いは刈取装置の接地センサが設置を感知した場合には、刈取装置を上昇させると刈取作業中の旋回動作として刈取装置の駆動を停止させる。 Hereinafter, embodiments of the present invention will be described with reference to examples shown in the drawings.

A shift lever 62 is provided on the side of the cockpit 31, and the drive speed of the traveling device is steplessly changed by the forward / backward tilting operation of the shift lever 62.
The swing sorting shelf 1 is provided with a transfer plate 34 having a feed protrusion formed on the lower side of the threshing net 24, and in an armor plate shape with inclined plates 35 spaced from the end of the transfer plate 34 to the rear. The arranged chaff sheave 2 is provided, and the grains are mainly subjected to the leakage selection while being oscillated and transferred by receiving the cereals transferred from the transfer plate 34 or the straw debris discharged from the discharge port 23. At the end of the chaff sheave 2, a straw rack 36 is disposed below the dust chamber 26 to discharge straw waste while swinging and transferring it. Reference numeral 3 denotes a glenive, which receives a sorter leaked from the chaff shib 2 and sorts out the grains.
The red pepper 4 is provided at the lower part of the transfer plate 34, opens the main air blowing port 6 toward the main sorting air passage 5 on the rear side, and opens the sub air blowing port 8 toward the sub sorting air passage 7. With the rotation of the fan 37, the compressed air is blown out from these air blowing ports 6, 8, and from the main sorting air passage 5 and the sub-sorting air passage 7 through the sorting gap portion of the swing sorting shelf 1, etc. It flows as suction air.
An air blow 9 is provided between the main air outlet 6 and the sub air outlet 8 as air blowing direction changing means. The rear end surface 11 of the air blow 9 is an inclined surface that descends rearward, and the upper plate 38 slightly protrudes rearward. The lower plate 39 extends rearward from the upper plate 38, and the guide plate 13 at the front end portion of the grain 3 is opposed to the rear side of the rear end surface 11. The guide plate 13 is appropriately below the rear extension surface of the upper plate 38 and is not in contact with the upper end portion or the rear end surface 11 of the upper plate 38 even if the swing sorting shelf 1 swings back and forth. It is configured as follows.
A sub-air blowing port 8 is formed between the upper plate 38 and the guide plate 40 facing the upper side, and the gap between the upper plate 38 and the guide plate 40 is wide on the Karatsu 4 side and narrow on the sub-selection air passage 7 side. It is formed in such a manner that the air is squeezed sequentially so that the air blows faster. The auxiliary sorting air passage 7 is formed by narrowing the guide plate 13 integrally with the swing sorting shelf 1 and the guide plate 41 provided on the lower surface of the terminal end of the transfer plate 34 so as to be narrowed sequentially. The sorting air guided by the air is blown up above the swinging sorting shelf 1 through a gap portion 42 between the front end portion of the transfer plate 34 and the inclined plate 35 at the front end portion of the chaff sheave 2 facing the rear side. doing. Further, a gap portion 43 is formed between the lower edge of the inclined plate 35 and the upper edge of the guide plate 13 so as to open from the sub-selection air passage 7 to the upper surface of the grain 3. The selected item is configured to be guided onto the grain 3.
In this manner, the sorting air blown out from the sub-air blowing port 8 is increased in wind speed and guided through the sub-sorting air passage 7 to the spacing portion 42. Therefore, the transfer plate is moved by the wind pressure blown upward in the spacing portion 42. 34, the threshing that is sent to the spacing portion 42 is floated here, and straw scraps and the like are easily blown to the rear portion of the chaff sheave 2, so that the grains are easily leaked, and the oscillating transfer sorting is performed. The action is performed quickly and smoothly.
Further, the wind rate 9 is supported by the pivot shaft 50 so as to be rotatable up and down, and when the processed material layer thickness sensor 51 provided on the transfer plate 34 detects a large number of threshing processed products, it is rotated upward to provide a fan. increasing the volume of air sent to many takes in sub screened air path 7 sorting air from 37, so that to reduce the volume of air sent to the secondary sorting air path 7 by rotating downwards when detecting the small threshing treated Automatically controlled.
FIG. 4 shows a block diagram of automatic control for controlling the vertical rotation of the wind rate 9.
The signals input to the wind split controller 61 are the clutch signal of the threshing clutch sensor 52 that detects whether the threshing device 15 is turned on or off, the ON / OFF signal of the automatic control switch 54, and the angle of the wind split 9 of the wind split angle sensor 55. Detecting the supply amount detection signal of the threshing processed product detected by the processed product layer thickness sensor 51, the setting angle signal of the wind split angle setting dial 57, the parking pedal depression signal from the parking pedal sensor 58, and the operation position of the shift lever 62 are detected. A neutral position signal from the main speed change sensor 59 and a travel speed signal from the vehicle speed sensor 60, and an angle control signal for the wind rate 9 is output to the wind rate drive motor 53.
When the air control controller 61 turns on the automatic control switch 54, it automatically controls the air split drive motor 53 according to the amount of the threshing processed product from the processed product layer thickness sensor 51. When the detected amount by the processed material layer thickness sensor 51 is large, the air division 9 is rotated upward so as to increase the air volume of the selected air flowing through the sub-selected air path 7, and the detected amount by the processed material layer thickness sensor 51 is increased. In the case of a small amount, the wind split drive motor 53 is driven in a direction to rotate the wind split 9 downward so as to reduce the volume of the sort wind flowing through the sub-sort wind path 7, but the threshing clutch sensor 52 is on. In addition, when the travel stop detection means D detects a state where the aircraft has stopped traveling, that is, when it can be handled, the air volume of the selected wind flowing through the sub-selected air path 7 by rotating the air split 9 downward. The air split drive motor 53 is controlled so as to decrease.
The travel stop detection means (D) detects whether the parking pedal sensor 58 detects the depression of the parking pedal, the main transmission sensor 59 detects the neutrality of the shift, or the vehicle speed sensor 60 detects zero speed. Determine the stop state.
The main air blowing port 6 is formed with the second air split 10 and the air guide plate 44, and the front end of the air guide plate 44 is the front end 45 of the upper air blow 9 or the front end 46 of the lower second air blow 10. The wind receiving area from the tang 4 side by the lower plate 39 of the wind rate 9 is widened so that the air blowing force between the wind rate 9 and the wind guide plate 44 is increased. Thus, it is configured to improve the air contact along the granule 3 in the main sorting air passage 5. The rear end portion of the air guide plate 44 is also set in front of the lower end edge of the rear end surface 11 of the upper wind rate 9 so that the grains flowing down on the rear end surface 12 are not disturbed.
Further, the rear end surface 11 of the airflow 9 and the rear end surface 12 of the second airflow 10 in each step are both formed in a step-like manner as a downward slope, and the rear end surface 12 of the lowermost step is the first receiving plate 14. It is on top.
Each inclined plate 35 is pivotally supported by the side frame portion of the swing sorting shelf 1, and the steep inclination angle becomes wider as the front and rear intervals become larger, and the threshing sort is easily leaked.
In a combine equipped with an exhaust purification device that raises the temperature of the exhaust pipe and incinerates the particulates in order to regenerate the filter that collects particulates in the exhaust gas generated from the engine E, the threshing device 15 is treated during regeneration of the filter. The filter is heated by increasing the driving load by setting to deep handling by the automatic depth control, or by increasing the driving load by rotating the airflow 9 upward.
Further, in the engine rotation control for automatically controlling the rotation speed of the engine E, the engine is controlled even if the rotation speed is instructed by the accelerator lever under the condition that the auger discharge clutch is cut off, the threshing and threshing clutch is turned off and the traveling main transmission lever is made neutral. A fuel-saving operation is performed by controlling the rotational speed to be lower by several percent than the indicated rotational speed. In this case, if the actual rotational speed before the condition is satisfied is lower than the accelerator lever instruction rotational speed, the speed is not increased. When the parking brake is turned off from on, when the accelerator lever is moved more than a predetermined value, or when the engine automatic control switch is turned off and turned on again, the engine speed is returned to the accelerator lever instruction speed. When the engine speed is lower than the command speed, the display lamp of the engine automatic control switch is blinked. The blinking of the display lamp is changed to continuous lighting when the engine speed is returned to the designated speed.
Further, when the reaping device is lowered and travels a predetermined distance or when the grounding sensor of the reaping device senses installation, when the reaping device is raised, the driving of the reaping device is stopped as a turning operation during the mowing operation.
