前記した従来のコンバインの構成において、扱胴で脱穀された被処理物の中には正常な穀粒の他に稲ワラの中に単粒がささったささり粒、枝梗粒、排藁くず等が含まれているが、これらの被処理物をさらに二番処理室の二番処理胴で処理して穀粒とその他の排藁などに分離して前記排藁など、穀粒以外のものは排塵処理胴により処理をした後、排塵処理室からの漏下物以外は圃場に廃棄している。すなわち、扱胴で正常に脱穀されなかったささり粒、枝梗粒などを複数の工程でさらに処理して正常な穀粒を得て、これとその他の被処理物とを分けて、穀粒を十分回収するようにしている。 In the structure of the conventional combine as described above, the processed material that has been threshed by the handling cylinder has a normal grain and a single grain in rice straw, branch grains, waste litter, etc. However, these objects to be processed are further processed in the second processing cylinder of the second processing chamber and separated into grains and other wastes, etc. After processing with the dust processing cylinder, all the waste from the dust processing chamber is discarded in the field. That is, the grain, branch branch, etc. that were not normally threshed by the handling cylinder are further processed in a plurality of steps to obtain a normal grain, and this is separated from other objects to be processed. We collect enough.
しかし、従来のコンバインの構成では排塵処理室に投入されて排塵処理胴に周設された螺旋によって処理された物で、排塵処理室から漏下する物は全て揺動棚上に落下させていた。 However, in the conventional combine structure, all the material that has been thrown into the dust processing chamber and processed by the spiral around the dust processing cylinder, and leaked from the dust processing chamber, falls onto the swing shelf. I was letting.
そのため、排塵処理室から漏下する穀粒は揺動棚上に揺動棚の前方から送られてくる排藁と混合されるため揺動棚上での穀粒の選別作業は易しいものとはいえず、中には穀粒が排藁に混入されたまま、排藁と共に外部に排出されることがあった。
また、一般に、排塵処理胴で処理された被処理物のうち、排塵処理胴の前方部では受網から漏下する穀粒は多いが、後方部では粒がきわめて少なく逆に藁くずの漏下が急増する。
Therefore, the grain that leaks from the dust disposal chamber is mixed with the waste that is sent from the front of the rocking shelf onto the rocking shelf, so that it is easy to select the grain on the rocking shelf. However, some grains were sometimes discharged to the outside along with the waste while being mixed with the waste.
Also, in general, among the objects to be processed in the dust removal cylinder, there are many grains that leak from the receiving net in the front part of the dust removal cylinder, but there are very few grains in the rear part. Leakage increases rapidly.
本発明の課題は、扱胴で正常に脱穀されなかったささり粒、枝梗粒などを確実に脱穀処理して回収することができる穀粒の回収性能を向上させた脱穀装置を提供することである。 The subject of this invention is providing the threshing apparatus which improved the collection | recovery performance of the grain which can carry out the threshing process reliably and can collect | recover the grains which were not normally threshed with the handling cylinder, a branch raft, etc. is there.

揺動棚51は図示しない揺動棚駆動機構の作動により上下前後方向に揺動するので、被処理物は矢印D方向(図4、図5)に移動しながら、唐箕79からの送風を受けて風力選別され、比重の重い穀粒はシーブ53および選別網63を矢印E方向に通過し、一番棚板64で集積され、一番螺旋65から一番揚穀筒16(図1)を経てグレンタンク30へ搬送される。グレンタンク30に貯留された穀粒は、オーガ18、19を経由してコンバイン1の外部へ搬送される。 Since the swing shelf 51 swings up and down and forward and backward by the operation of a swing shelf drive mechanism (not shown), the workpiece is moved in the direction of arrow D (FIGS. 4 and 5) and receives air from the Karatsu 79. Grain that has been subjected to wind sorting and has a high specific gravity passes through the sheave 53 and the sorting net 63 in the direction of arrow E, and is accumulated on the first shelf board 64, and from the first spiral 65 to the first milling cylinder 16 (FIG. 1). After that, it is conveyed to the Glen tank 30. The grains stored in the Glen tank 30 are conveyed to the outside of the combine 1 via the augers 18 and 19.
揺動棚51の上の被処理物のうち軽量のものは、揺動棚51の揺動作用と唐箕79のファン79aによる送風に吹き飛ばされてシーブ53の上を矢印D方向に移動し、ストローラック62の上で大きさの小さい二番穀粒は矢印G方向に落下して二番棚板85に集められ、二番螺旋86で二番揚穀筒87へ搬送される(図4、図5)。 Among the objects to be processed on the swing shelf 51, the lighter ones are blown off by the swing action of the swing shelf 51 and the air blown by the fan 79 a of the Karatsu 79 and move on the sheave 53 in the direction of arrow D, The second small grain on the rack 62 falls in the direction of arrow G and is collected on the second shelf 85, and is conveyed to the second lifting cylinder 87 by the second spiral 86 (FIGS. 4 and 4). 5).
二番穀粒は、正常な穀粒、枝梗粒、藁くずおよび藁くずの中に正常な穀粒が刺さっているササリ粒などの混合物であり、二番揚穀筒87の中を二番揚穀筒ラセン(図示せず)により矢印H方向(図4、図5、図7参照)に揚送されて、二番処理室入口から二番処理室67の上方へ放出される。二番処理室67の下部に軸架する二番処理胴70は図示しない駆動装置により図7の矢印J方向に回転する。二番穀粒は二番処理胴70に植設してある多数の処理歯70a(図5)と螺旋70c(図4)に衝突しながら矢印I方向(図4、図5)に進行する間に二番穀粒の分離と枝梗粒の枝梗の除去を行い、一部の被処理物は二番処理胴受網75から矢印C2方向(図4、図5)に通過して揺動棚51に落下し、大部分の被処理物は二番処理室67の終端から二番処理胴送風羽根70bの送風に送られて矢印C3方向(図4、図5)に揺動棚51に落下して扱室66からの被処理物と合流する。 The second kernel is a mixture of normal kernels, branch stems, crumbs and scorpion grains in which normal grains are stabbed in the crumbs. It is pumped up in the direction of arrow H (see FIGS. 4, 5, and 7) by a milled helix (not shown) and discharged upward from the second processing chamber 67 to the second processing chamber 67. The second processing cylinder 70 pivoted on the lower portion of the second processing chamber 67 is rotated in the direction of arrow J in FIG. 7 by a driving device (not shown). While the second grain proceeds in the direction of the arrow I (FIGS. 4 and 5) while colliding with the numerous treatment teeth 70a (FIG. 5) and the spiral 70c (FIG. 4) planted in the second treatment cylinder 70. The separation of the second grain and the removal of the branch infarction are performed, and a part of the workpiece passes through the second treatment trunk receiving net 75 in the direction of arrow C2 (FIGS. 4 and 5) and swings. Most of the objects to be processed fall on the shelf 51 and are sent from the end of the second processing chamber 67 to the second processing cylinder air blowing blade 70b to the swing shelf 51 in the direction of arrow C3 (FIGS. 4 and 5). It falls and merges with the object to be processed from the handling chamber 66.
本実施の形態の特徴は排塵処理室68を扱室66の後側方で、隣接する部位に設け、扱室66の被処理物搬送方向終端部と排塵処理室68の被処理物搬送方向始端部との接続部には排塵処理室入口68aとなる開口を設けることである。 The feature of the present embodiment is that the dust disposal chamber 68 is provided on the rear side of the handling chamber 66 at an adjacent portion, and the workpiece transport direction end portion of the handling chamber 66 and the workpiece treatment in the dust disposal chamber 68 are conveyed. An opening to be a dust removal processing chamber inlet 68a is provided at a connection portion with the direction start end portion.
さらに本実施の形態のもう一つの特徴は、二番処理室67を排塵処理室68の下方に設け、かつ排塵処理室68から漏下する被処理物を二番処理室67の後方部で受け、二番処理室67の前方に搬送するように構成したことである。 Furthermore, another feature of the present embodiment is that the second treatment chamber 67 is provided below the dust removal treatment chamber 68 and the object to be treated that leaks from the dust treatment chamber 68 is located at the rear of the second treatment chamber 67. It is configured to be transferred to the front of the second processing chamber 67.
扱室66の被処理物搬送方向終端部に到達した被処理物の中で、藁くずなど短尺のものは、排塵処理室入口68aから矢印A2(図6)方向に投入されて排塵処理室68に入り、排塵処理室68では回転する排塵処理胴71の螺旋71aにより矢印K方向(図6)に搬送されながら処理される。 Among the objects to be processed that have reached the terminal end of the object to be processed in the handling chamber 66, short objects such as scraps are thrown into the direction of the arrow A2 (FIG. 6) from the dust discharging chamber inlet 68a and are subjected to dust processing. It enters the chamber 68 and is processed while being conveyed in the direction of the arrow K (FIG. 6) by the spiral 71a of the rotating dust exhausting cylinder 71 in the dust exhausting chamber 68.
排塵処理室68に入った少量の穀粒を含む藁くずを主体とする被処理物の中の漏下物は受け網76(図7)から二番処理室67の二番処理胴70の上に落ち、該二番処理胴70の回転で二番処理胴70の後方側に周設された螺旋70c(図4)または処理歯70a(図5)によって搬送されて二番処理胴70の前方側に搬送されながら処理されて二番処理胴70の下方に設けられた受け網75を矢印C3方向に通り抜けて揺動棚51の移送棚51a上に送られる。 Leakage in the processing object mainly composed of sawdust including a small amount of grain that has entered the dust disposal chamber 68 is transferred from the receiving net 76 (FIG. 7) to the second processing cylinder 70 of the second processing chamber 67. The second processing cylinder 70 is rotated by the spiral 70 c (FIG. 4) or the processing teeth 70 a (FIG. 5) provided around the rear side of the second processing cylinder 70 by the rotation of the second processing cylinder 70. It is processed while being conveyed forward, passes through the receiving net 75 provided below the second processing cylinder 70 in the direction of arrow C3, and is sent onto the transfer shelf 51a of the swing shelf 51.
従来の脱穀装置では排塵処理室68からの漏下物は二番処理室67に送られることなく、全量揺動棚51へ回収されていたので、揺動棚51上での穀粒と藁くずなどとの選別が効率的に行えるとはいえなかった。 In the conventional threshing apparatus, the leakage from the dust processing chamber 68 is not sent to the second processing chamber 67, but is recovered in its entirety on the swing shelf 51. Therefore, the grains and straws on the swing shelf 51 are collected. It could not be said that sorting with waste etc. could be performed efficiently.
しかし、図4〜図7に示す本実施の形態の構成により、排塵処理室68で処理された穀粒は振動棚51の移送棚51aへ回収され速やかに一番螺旋65に回収されるので脱穀ロスが低減する。 However, with the configuration of the present embodiment shown in FIGS. 4 to 7, the grains processed in the dust removal processing chamber 68 are recovered to the transfer shelf 51 a of the vibration shelf 51 and quickly recovered to the first spiral 65. Threshing loss is reduced.
また脱穀装置15は、排塵処理室68から二番処理室67へ漏下した被処理物は二番処理胴70により二番処理室67の前方に搬送され、単粒化処理される。この構成により排塵処理室68から漏下した単粒を含む枝梗粒及び穂切粒は直接二番処理胴70で単粒化され、二番処理室67前方の受網75から揺動棚51に送られて効率的に穀粒を回収できるという効果がある。 In the threshing device 15, the workpiece leaked from the dust processing chamber 68 to the second processing chamber 67 is transported to the front of the second processing chamber 67 by the second processing cylinder 70 and is processed into a single grain. According to this configuration, branch infarct grains and cut grains including single grains leaked from the dust removal processing chamber 68 are directly made into single grains by the second processing cylinder 70, and are swung from the receiving net 75 in front of the second processing chamber 67. It is sent to 51 and there exists an effect that a grain can be collected efficiently.
また、排塵処理胴71の後端部を脱穀装置15の後壁面15aに達する位置まで伸ばしているのに対して、二番処理胴70の後端部を脱穀装置15の後壁面15aに達しない長さとしていることも本実施の形態の特徴の一つである。 Further, while the rear end portion of the dust removal processing cylinder 71 is extended to a position reaching the rear wall surface 15a of the threshing device 15, the rear end portion of the second processing cylinder 70 reaches the rear wall surface 15a of the threshing device 15. One of the features of this embodiment is that the length is not set.
一般に排塵処理胴71で処理された被処理物のうち排塵処理胴71の前方部では受網76から漏下する穀粒は多いが、後方部では粒がきわめて少なく逆に藁くずの漏下が急増する。そのため、上記構成にすることで排塵処理胴68の前方部から二番処理胴70へ回収する穀粒の比率を上げることができる。 In general, among the workpieces processed by the dust disposal cylinder 71, there are many grains that leak from the receiving net 76 in the front part of the dust disposal cylinder 71, but there are very few grains in the rear part, and conversely, the leakage of the sawdust. The bottom increases rapidly. Therefore, the ratio of the grain collect | recovered to the 2nd process cylinder 70 from the front part of the dust removal process cylinder 68 can be raised by setting it as the said structure.
また、図4ないし図6に示すように、脱穀装置15の後部に横断流ファン91を設け、排塵処理室68を含む脱穀装置15内で発生する排塵のうち、比重の軽い藁くずおよび塵埃を含む空気を横断流ファン羽根車91aの回転による送風で吸引し、横断流ファン出口91b(図4、図5)から矢印L方向へ吹き出して、コンバイン1の外部へ放出する。 As shown in FIGS. 4 to 6, a crossflow fan 91 is provided at the rear of the threshing device 15, and among the dust generated in the threshing device 15 including the dust processing chamber 68, Air containing dust is sucked by blowing air by rotation of the cross-flow fan impeller 91a, blown out in the direction of arrow L from the cross-flow fan outlet 91b (FIGS. 4 and 5), and discharged to the outside of the combine 1.
横断流ファン91のある室から揺動棚51の終端部に矢印M(図4、図5)のように落ちた排塵の内、やや長めの藁くずはストローラック62で受けとめられ、揺動棚51の揺動運動と、唐箕79の送風力により矢印Fのように揺動棚51の終端部から排出され圃場に放出される。また、排塵のうち二番穀粒、三番穀粒など小径で比重の重いものは、揺動棚51の終端部のストローラック62あるいはシーブ53を矢印G方向へ通過して二番棚板85に落下し、再び二番処理室67において処理される。 Of the dust that has fallen as shown by the arrow M (FIGS. 4 and 5) from the chamber where the cross-flow fan 91 falls to the end of the swing shelf 51, slightly longer waste is received by the Strolack 62, and the swing shelf. As shown by the arrow F, it is discharged from the end portion of the swing shelf 51 by the swinging motion of 51 and the air blowing force of the Kara 79 and discharged to the field. Further, among the dust particles, those having a small diameter and heavy specific gravity, such as the second grain and the third grain, pass through the Strollac 62 or the sheave 53 at the end of the swing shelf 51 in the direction of the arrow G, and the second shelf board. It falls to 85 and processed in the second processing chamber 67 again.
扱室66を図6の矢印A方向に進行し、扱室66の終端に到達した被処理物の中の脱穀された穀稈(藁)で長尺のままのものは、図6に示す矢印A1方向に搬送され、排藁処理室95に投入される。排藁処理室95の入口部には図8に示すように水平方向に出入りして入口部を開放、または閉鎖する入口ダンパ95aを備え、入口ダンパ95aを開放した場合には、排藁は矢印P方向(図8)に落下して、藁用カッター92、93により切断される。藁用カッター92および93はそれぞれ駆動アクチュエータM3およびM4により制御された回転速度で回転駆動される。藁用カッター92および93で細かく切断された切藁は、駆動アクチュエータM5で回転駆動される螺旋状の拡散手段94で軸方向(コンバイン1の幅方向)に拡散されて圃場に落下放出される。 The threshing cereals (slags) that have been threshed in the material to be processed that have traveled in the direction of arrow A in FIG. 6 and have reached the end of the handling chamber 66 are shown in FIG. It is transported in the A1 direction and put into the waste disposal chamber 95. As shown in FIG. 8, the entrance portion of the waste disposal chamber 95 is provided with an entrance damper 95a that goes in and out in the horizontal direction to open or close the entrance portion, and when the entrance damper 95a is opened, the waste is indicated by an arrow. It falls in the P direction (FIG. 8) and is cut by the scissors cutters 92 and 93. The scissors cutters 92 and 93 are rotationally driven at a rotational speed controlled by drive actuators M3 and M4, respectively. The cuttings finely cut by the cutting cutters 92 and 93 are diffused in the axial direction (in the width direction of the combine 1) by the spiral diffusion means 94 that is rotationally driven by the driving actuator M5, and dropped and released to the field.
また、カッター92で切断しないで藁を自然落下させるドロッパ作業のため排藁処理室95の入口ダンパー95aを図8の参考線で示す位置に閉鎖した場合には、排藁は藁用カッター92で切断されることなく矢印Q方向に落下して圃場に放出される構成とする。 In addition, when the entrance damper 95a of the waste disposal chamber 95 is closed at the position indicated by the reference line in FIG. It is set as the structure which falls in the arrow Q direction and is discharge | released to a farm field, without cut | disconnecting.
本発明の実施の形態の脱穀装置15では、排塵処理室68の上面に設けたカバー68cを図3、図7に示すように開閉自在な構成とした。
従来のコンバインの脱穀装置15の上壁面の中で扱室66の上面カバー66bは開閉自在になっていたが、排塵処理胴71が扱胴69の後側部の比較的下方に配置されていたので、排塵処理胴71のメインテナンスには、作業者は扱室上面カバー66bを開けて、かがみ込む姿勢で作業をするしかなかった。排塵処理胴には藁くずがからみ付きやすく、藁くず除去作業が負担になっていた。
In the threshing apparatus 15 according to the embodiment of the present invention, the cover 68c provided on the upper surface of the dust removal processing chamber 68 is configured to be openable and closable as shown in FIGS.
The upper cover 66b of the handling chamber 66 is openable and closable in the upper wall surface of the conventional combine threshing device 15, but the dust removal processing cylinder 71 is disposed relatively below the rear side of the handling cylinder 69. Therefore, for maintenance of the dust removal processing cylinder 71, the operator has to open the handling chamber upper surface cover 66b and work in a state of bending. The dust removal cylinder was easily entangled with waste, and the waste removal work was a burden.
しかし、図7に示す実施の形態では脱穀装置15の上面近傍に排塵処理室68を配置したので、排塵処理室68の上面に上面カバー68cを設け、図7に示すように上面カバー68cを開閉自在な構成とした。そのため、排塵処理胴71にからみ付いた藁くず除去作業が容易になった。また、排塵処理胴71の螺旋71aの交換作業等の排塵処理胴71のメンテナンスが容易に行えるようになった。 However, in the embodiment shown in FIG. 7, the dust removal processing chamber 68 is disposed near the upper surface of the threshing device 15. Therefore, an upper cover 68c is provided on the upper surface of the dust removal processing chamber 68, and as shown in FIG. Is configured to be openable and closable. Therefore, the waste removal work entangled with the dust removal processing cylinder 71 can be easily performed. Further, maintenance of the dust removal processing cylinder 71 such as replacement of the spiral 71a of the dust collection processing cylinder 71 can be easily performed.
本発明の実施の形態のコンバインとして、エンジン28の回転数に同期して刈り取った穀稈を脱穀装置15に供給搬送するシンクロ搬送装置21(刈取装置6から脱穀装置15に穀稈を引き継ぐ前記供給搬送装置(図示せず)など)を備えたコンバインを用いる場合に、シンクロ搬送装置21の穀稈搬送速度がある設定値以上に達すると、それに伴いフィードチェン14の速度(第一設定速度)V1であった回転速度が速度(第二設定速度)V2に変更できるフィードチェン回転速度制御用クラッチ22を設けた歯車伝動機構23を用いる。 As a combine according to an embodiment of the present invention, a synchronized transfer device 21 that supplies and conveys cereals harvested in synchronization with the rotational speed of the engine 28 to the threshing device 15 (the supply that takes over cereals from the reaping device 6 to the threshing device 15) When using a combine equipped with a transport device (not shown), etc., if the cereal transport speed of the synchro transport device 21 reaches a set value or more, the speed of the feed chain 14 (first set speed) V1 accordingly. The gear transmission mechanism 23 provided with the feed chain rotational speed control clutch 22 that can change the rotational speed to the speed (second set speed) V2 is used.
前記歯車伝動機構23は図9に示し、フィードチェン14の回転速度制御のフローを図10(a)に、車速とフィードチェン14の回転速度の関係を図10(b)に示す。歯車伝動機構23にはフィードチェン14の回転速度を速度V1と速度V2に切り替えるための切替レバー25と該レバー作動用モータ26が設けられている。また、シンクロ搬送装置21とフィードチェン14は刈取装置6を駆動するための刈取・脱穀クラッチ27を介してエンジン28に連結している。 The gear transmission mechanism 23 is shown in FIG. 9, the flow of the rotational speed control of the feed chain 14 is shown in FIG. 10 (a), and the relationship between the vehicle speed and the rotational speed of the feed chain 14 is shown in FIG. 10 (b). The gear transmission mechanism 23 is provided with a switching lever 25 for switching the rotation speed of the feed chain 14 between the speed V1 and the speed V2 and a motor 26 for operating the lever. Further, the synchro transport device 21 and the feed chain 14 are connected to the engine 28 via a mowing / threshing clutch 27 for driving the mowing device 6.
図示しない車速センサーが所定の車速V1及びそれ以下である時にはフィードチェン14の回転速度制御用クラッチ22は速度V1側に接続し、車速センサーが所定の車速V1よりも大きい車速であることを検知することによって、フィードチェン回転速度制御用クラッチ22は速度V2側に切り替わるようにモータ26が駆動制御される。 When a vehicle speed sensor (not shown) is at or below a predetermined vehicle speed V1, the rotational speed control clutch 22 of the feed chain 14 is connected to the speed V1 side, and the vehicle speed sensor detects that the vehicle speed is higher than the predetermined vehicle speed V1. Thus, the motor 26 is driven and controlled so that the feed chain rotational speed control clutch 22 is switched to the speed V2 side.
このとき、フィードチェン14の回転速度が速度V1より大きい速度V2であるときには、シンクロ搬送装置21の穀稈搬送速度が最高速度になる時よりも速いか又は同スピード程度となるような構成とする。このようなシンクロ搬送装置21を用いることで、刈取装置6から脱穀装置15に穀稈を引き継ぐときに、穀稈の搬送姿勢の乱れが生じたり、詰まりなどが生じることがない。 At this time, when the rotation speed of the feed chain 14 is a speed V2 higher than the speed V1, the cereal transport speed of the synchro transport device 21 is faster than or equal to the maximum speed. . By using such a synchro conveying device 21, when the cereal is handed over from the reaping device 6 to the threshing device 15, the cereal conveying posture is not disturbed or clogged.
また、扱室66の入口部での穀稈の層厚が大きくなるに伴い、抵抗も大きくなり、脱穀姿勢の乱れによる穂切れや詰まりの発生が起こりやすいという問題がある。
そこで図11に示すようにフィードチェン14の回転速度をシンクロ搬送装置21の穀稈搬送速度の最高値よりも速い、一定値に設定する構成にしても良い。このような構成にすると、扱室66の入口部での穀稈の層厚が大きくなっても、あらゆる速度域でも脱穀装置15での穀稈の乱れが無く、フィードチェン14の回転速度がシンクロ搬送装置21の穀稈搬送速度よりも速いため、シンクロ搬送装置21での穀稈層厚がフィードチェン14部分での穀稈層厚よりも大きくなるので穀稈引継部でのフィードチェン14の取り込みが良くなり、穀稈の詰まり等の問題が生じない。
Moreover, as the layer thickness of the cereals at the entrance of the handling chamber 66 increases, the resistance also increases, and there is a problem that the occurrence of cuttings and clogging is likely to occur due to disturbance of the threshing posture.
Therefore, as shown in FIG. 11, the rotation speed of the feed chain 14 may be set to a constant value that is faster than the maximum value of the grain transport speed of the synchro transport device 21. With such a configuration, even if the layer thickness of the cereal at the entrance of the handling chamber 66 is increased, the threshing device 15 is not disturbed at any speed range, and the rotation speed of the feed chain 14 is synchronized. Since the speed of the cereal conveying speed of the transport device 21 is faster, the thickness of the cereal layer in the synchro conveying device 21 is larger than the thickness of the cereal layer in the portion of the feed chain 14, so And problems such as clogging of cereals do not occur.
