本発明は、刈取穀稈を脱穀フィードチェーンにより搬送しながら脱穀処理する脱穀装置と、刈取部で刈り取った刈取穀稈を脱穀フィードチェーンに向けて搬送する穀稈搬送装置とを備えたコンバインに関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine harvester including a threshing device that performs threshing processing while transporting a harvested grain culm by a threshing feed chain, and a grain culm transporting device that transports the harvested grain culm cut by the mowing unit toward the threshing feed chain.

この種のコンバインでは、従来、手刈りした穀稈を手動で脱穀フィードチェーンに供給して脱穀する枕扱ぎ作業に適した枕扱ぎ姿勢と、枕扱ぎ作業を規制して刈取部にて刈取られた穀稈を脱穀処理する通常作業姿勢とに切り換え自在な規制部材が備えられるとともに、この規制部材が枕扱ぎ姿勢に切り換わるとオン状態に切り換わる検出スイッチと、検出スイッチがオン状態に切り換わると、脱穀フィードチェーンの駆動速度を枕扱ぎ作業用の速度に調節する制御装置とが備えられたものがあった。そして、規制部材及び検出スイッチは、夫々、脱穀装置側に支持される状態で備えられていた（例えば、特許文献１参照。

上記従来構成では、規制部材及び検出スイッチは、夫々、脱穀装置側に支持される状態で備えられるから、次のような不利な点があった。 In the above-described conventional configuration, the regulating member and the detection switch are provided in a state of being supported by the threshing device side, respectively, and thus have the following disadvantages.

すなわち、脱穀装置は、その内部に、大きな重量を有するとともに高速で回転される扱胴が備えられるものであるから、刈取穀稈を扱胴により扱き処理する際に、脱穀装置は作業の実行に伴って強い振動が発生することになる。そして、規制部材や検出スイッチが、脱穀装置側に支持されるので、脱穀作業が実行されるに伴って発生する強い振動に起因して規制部材や検出スイッチが不具合を起こすおそれがあった。 That is, since the threshing device has a handling cylinder that has a large weight and is rotated at high speed inside the threshing device, the threshing device does not perform work when handling the harvested culm by the handling barrel. A strong vibration will be generated accordingly. Since the regulation member and the detection switch are supported on the threshing device side, there is a possibility that the regulation member and the detection switch may malfunction due to the strong vibration generated as the threshing work is performed.

そこで、枕扱ぎ作業の際には枕扱ぎ作業に適した運転状態で脱穀装置を作動させることにより作業を良好に行えるようにしながら、耐久性の向上を図ることが望まれていた。 Therefore, during the pillow handling work, it has been desired to improve durability while operating the threshing device in an operating state suitable for the pillow handling work so that the work can be favorably performed.

A manual operation unit for switching the restriction member is provided in a state of being connected to the restriction member,
A gripping portion of the manual operation portion that can be gripped is provided on the lateral outside of the machine body with respect to the regulation member.

本発明によれば、手動操作により規制部材が規制解除状態に切り換えられ、検出センサがそのことを検出すると、脱穀制御部は枕扱ぎ用の運転状態になるように脱穀装置の駆動速度を制御する。つまり、作業者が枕扱ぎ作業を行う場合、例えば、刈取作業用の運転状態における駆動速度よりも低速で駆動される等、脱穀フィードチェーンが枕扱ぎに適した運転状態で駆動される。 According to the present invention, the regulation member is switched to the regulation release state by the manual operation, and when the detection sensor detects that, the threshing control unit controls the drive speed of the threshing device so as to be in the operation state for pillow handling. To do. That is, when a worker performs a pillow operation, the threshing feed chain is driven in an operation state suitable for pillow operation, such as being driven at a speed lower than the drive speed in the operation state for mowing work.

規制部材が規制状態であれば、手動で穀稈を枕扱き穀稈供給部に供給することができないので、枕扱き作業時には、作業者は常に規制部材を規制解除状態に切り換える必要がある。その結果、枕扱き作業時においては、枕扱ぎ用の運転状態にて脱穀装置が駆動されるので、作業を良好に行うことができる。 If the regulating member is in the regulated state, the grain culm cannot be manually supplied to the pillow culm feeder, so that the operator must always switch the regulating member to the deregulated state during the pillow handling work. As a result, during the pillow handling work, the threshing device is driven in the operating state for pillow handling, so that the work can be favorably performed.

支持部材により検出センサが支持され、規制部材は、横向き軸芯周りで揺動自在に支持部材に支持されている。このように検出センサ及び規制部材が穀稈搬送装置側に支持されているので、脱穀装置側に備える場合に比べて強い振動が作用しないので不具合を起こすおそれが少ないものになって、耐久性の向上を図ることができる。 The detection sensor is supported by the support member, and the regulation member is supported by the support member so as to be swingable around the lateral axis. Since the detection sensor and the regulation member are supported on the grain culm transporting device side as described above, strong vibration does not act as compared with the case where the grain slaughtering device side is equipped, so that there is less possibility of causing trouble, and durability is improved. It is possible to improve.

しかも、支持部材を追加して検出センサ及び規制部材を支持する構成とすることで、穀稈供給の規制に適した位置に規制部材を備えることができ、規制部材の状態を検出するのに適した位置に検出センサを備えることができる。 Moreover, by adding a support member to support the detection sensor and the regulation member, the regulation member can be provided at a position suitable for regulation of grain culm supply, and is suitable for detecting the state of the regulation member. A detection sensor can be provided at a different position.

従って、枕扱ぎ作業の際には、枕扱ぎ作業に適した運転状態で脱穀装置を作動させることにより作業を良好に行うことができるものでありながら、耐久性の向上を図ることが可能となり、しかも、合理的な支持構造により簡単な構造改良で対応することができる。 Therefore, during the pillow handling work, it is possible to perform the work well by operating the threshing device in an operation state suitable for the pillow handling work, but it is possible to improve the durability. In addition, the rational support structure allows a simple structural improvement.

また、規制部材に連結された状態で手動操作部が備えられるので、作業者は、この手動操作部を手で持って規制部材の姿勢切り換え操作を行うことができる。規制部材は、穀稈の供給を規制するのに適した位置に設けられるが、手動操作部を規制部材とは異なる操作し易い位置に備えることができ、規制部材を手で持って操作するのに比べて操作性の向上を図ることが可能となる。 Further, since the manual operation part is provided in a state of being connected to the restriction member, the operator can hold the manual operation part by hand to perform the attitude switching operation of the restriction member. The regulation member is provided at a position suitable for regulating the supply of the grain culm, but the manual operation portion can be provided at a position different from the regulation member that is easy to operate, and the regulation member can be operated by holding it by hand. It is possible to improve operability as compared with.

規制部材２６及び規制状態検出センサ２７は、縦搬送装置１１における供給搬送装置１５を支持するフレーム体３０に支持されている。具体的には、規制部材２６及び規制状態検出センサ２７は、フレーム体３０に連結固定された支持部材としての支持ブラケット４６に支持されている。 The regulation member 26 and the regulation state detection sensor 27 are supported by a frame body 30 that supports the supply/conveyance device 15 in the vertical conveyance device 11. Specifically, the regulation member 26 and the regulation state detection sensor 27 are supported by a support bracket 46 as a support member that is fixedly connected to the frame body 30.

図６に示すように、支持ブラケット４６は、板材を平面視で略Ｌ字形に折り曲げたベース部４６Ａと、ベース部４６Ａの後側端部から横向きに固定延設された支持軸部４６Ｂと、板材を側面視で略Ｌ字形に折り曲げて形成されてベース部４６Ａの前後途中部の横側面に一体的に連結されたセンサ支持部４６Ｃとを備えている。又、補強用リブ４６Ｄ、及び、後述するコイルバネ４７が係止されるバネ受け部４６Ｅも備えている。 As shown in FIG. 6, the support bracket 46 includes a base portion 46A formed by bending a plate material into a substantially L shape in a plan view, a support shaft portion 46B laterally fixed and extending from a rear end portion of the base portion 46A, It is provided with a sensor support portion 46C which is formed by bending a plate material into a substantially L shape in a side view and is integrally connected to a lateral side surface of a front and rear midway portion of the base portion 46A. Further, it also has a reinforcing rib 46D and a spring receiving portion 46E to which a coil spring 47 described later is locked.

この支持ブラケット４６は、ベース部４６Ａの前側端部がフレーム体３０に一体的に連結固定された縦向き姿勢の取付板４９にボルト締結により連結されて支持されている。そして、図２に示すように、この支持ブラケット４６は、刈刃９により刈り取られて縦搬送装置１１により搬送される刈取穀稈の搬送経路の上方近傍箇所に位置する状態で設けられている。又、支持ブラケット４６は、上下方向に幅狭で且つ機体前後方向に長尺状に設けられており、搬送経路の上方近傍箇所に位置して穀稈送り方向に沿う形態で設けられている。 The support bracket 46 is supported by being bolted to a mounting plate 49 in a vertical posture in which the front end of the base portion 46A is integrally coupled and fixed to the frame body 30. Then, as shown in FIG. 2, the support bracket 46 is provided in a state of being positioned in the vicinity of the upper part of the transfer path of the cut culm that is cut by the cutting blade 9 and transferred by the vertical transfer device 11. Further, the support bracket 46 is provided in a narrow shape in the vertical direction and in an elongated shape in the machine front-rear direction, and is provided at a position near the upper part of the transport path and along the grain culm feeding direction.

図９に示すように、ベース部４６Ａのセンサ支持部４６Ｃに対応する箇所には、規制状態検出センサ２７の回動軸２７Ａが通過するための開口４８が形成されている。そして、又、センサ支持部４６Ｃの下側面がセンサ受け部４１に形成された延長支持部４４にボルト締結により連結されている。 As shown in FIG. 9, an opening 48 through which the rotation shaft 27A of the regulation state detection sensor 27 passes is formed at a location corresponding to the sensor support portion 46C of the base portion 46A. The lower side surface of the sensor support portion 46C is connected to the extension support portion 44 formed on the sensor receiving portion 41 by bolt fastening.

図６に示すように、規制部材２６は、棒材を略Ｌ字状に折り曲げて形成され、機体前後方向に沿って延びる状態で備えられる。機体前部側に位置する基端側には、板材をチャンネル形に屈曲形成した基端側支持部２６ａが一体的に連結固定され、この基端側支持部２６ａが支持ブラケット４６の支持軸部４６Ｂに回動自在に外嵌支持されている。従って、規制部材２６は、支持軸部４６Ｂの軸芯Ｐ２周りで回動自在に支持ブラケット４６に支持されている。 As shown in FIG. 6, the restricting member 26 is formed by bending a bar material into a substantially L shape, and is provided in a state of extending along the longitudinal direction of the machine body. A base end side support part 26a formed by bending a plate material into a channel shape is integrally connected and fixed to the base end side located on the front side of the machine body, and the base end side support part 26a is a support shaft part of the support bracket 46. It is externally fitted and supported by 46B so as to be rotatable. Therefore, the regulation member 26 is supported by the support bracket 46 so as to be rotatable around the axis P2 of the support shaft portion 46B.

図３，７に示すように、規制部材２６は、受止め台２５よりも左側すなわち、機体横外側に位置する状態で設けられている。そして、規制部材２６を切り換え操作するための手動操作部としての握り操作部５１が、規制部材２６とは別体の棒材にて形成して備えられている。この握り操作部５１は、その基端側箇所が基端側支持部２６ａに一体的に連結固定され、機体横外方側の後斜め方向に向けて片持ち状に延設されている。一方、規制部材２６は、受止め台２５よりも上方に延びて枕扱ぎ作業の邪魔になるように後斜め方向に向けて片持ち状に延設されている。 As shown in FIGS. 3 and 7, the restriction member 26 is provided on the left side of the receiving base 25, that is, on the lateral outside of the machine body. Further, a gripping operation portion 51 as a manual operation portion for switching operation of the regulation member 26 is provided by being formed by a bar member which is separate from the regulation member 26. The grip operation portion 51 has a base end side portion integrally connected and fixed to the base end side support portion 26a, and extends in a cantilever shape toward the rear oblique direction on the lateral outside of the machine body. On the other hand, the regulating member 26 extends upward from the receiving base 25 and extends in a cantilever manner in the rear oblique direction so as to interfere with the pillow handling work.

従って、規制部材２６により手動での穀稈の供給を規制することが可能でありながらも、機体横側外方側から作業者が握り操作部５１を操作し易いものとなり、操作性が良好なものとなる。 Therefore, although it is possible to manually regulate the supply of the grain culms by the regulation member 26, it becomes easy for the operator to operate the grip operation unit 51 from the outside of the machine side, and the operability is good. Will be things.

図６に示すように、基端側支持部２６ａから左外側方に突出する状態で棒状のバネ受け部５２が一体的に形成され、さらに、このバネ受け部５２の途中部から機体前方側に向けて突出する棒状の切換作用部５３が一体的に形成されている。 As shown in FIG. 6, a rod-shaped spring receiving portion 52 is integrally formed in a state of protruding from the base end side supporting portion 26a to the left outer side, and further, from the middle portion of the spring receiving portion 52 to the front side of the machine body. A bar-shaped switching action portion 53 that projects toward the outside is integrally formed.

基端側支持部２６ａに一体的に形成されたバネ受け部５２と、支持ブラケット４６のバネ受け部４６Ｅとに亘って引っ張り作用するコイルバネ５４が張設され、規制部材２６はこのコイルバネ５４の付勢力により前方下方側に向けて回動付勢されている。又、規制部材２６の基端側支持部２６ａには、受止め台２５側に向けて突出する係止部５５が形成されている。そして、規制部材２６が前方下方側へ回動付勢されてこの係止部５５が受止め台２５の上面に接当して、規制部材２６のそれ以上の下方側に向けての回動が規制される構成となっている。このように、係止部５５が受止め台２５の上面に接当して回動が規制されている状態が規制状態に対応する。 A coil spring 54 is stretched over the spring receiving portion 52 formed integrally with the base end side support portion 26a and the spring receiving portion 46E of the support bracket 46, and the regulating member 26 is attached with the coil spring 54. It is rotationally biased toward the lower front side by the force. Further, the base end side support portion 26a of the regulation member 26 is formed with a locking portion 55 that projects toward the receiving base 25 side. Then, the regulation member 26 is urged to rotate forward and downward, and the locking portion 55 abuts on the upper surface of the receiving base 25, so that the regulation member 26 is further rotated downward. It is regulated. In this way, the state in which the locking portion 55 is in contact with the upper surface of the receiving base 25 and the rotation is restricted corresponds to the restricted state.

握り操作部５１を握り操作してコイルバネ５４の付勢力に抗して手動で規制状態にある規制部材２６を機体前方側に揺動操作して、所定揺動位置を越えると、すなわち、規制部材２６側のバネ受け部５２がデッドポイントを越えると、コイルバネ５４は規制部材２６を後方下方側に揺動付勢する状態から前方下方側に揺動付勢する状態に切り換わる。前方下方側に揺動付勢される規制部材２６は、挟持用案内杆１５ｂを支持する一対の支持ロッド３３のうちの後部側の支持ロッド３３の外方突出部分に接当してそれ以上の前方下方側への回動が規制される。このように、規制部材２６の回動が規制されている状態が規制解除状態に対応する。 When the gripping operation portion 51 is gripped and the regulation member 26 in the regulated state is manually rocked against the biasing force of the coil spring 54 toward the front side of the machine body to exceed the predetermined rocking position, that is, the regulation member. When the spring receiving portion 52 on the 26 side exceeds the dead point, the coil spring 54 is switched from the state in which the regulating member 26 is urged to swing downward and rearward to the state in which it is urged to swing downward and forward. The restricting member 26, which is urged to swing downward in the front direction, comes into contact with an outwardly projecting portion of the support rod 33 on the rear side of the pair of support rods 33 that supports the guide rod 15b for nipping, and further restricts it. Rotation to the lower front side is restricted. In this way, the state in which the rotation of the regulation member 26 is regulated corresponds to the regulation release state.

図７，８，９に示すように、規制部材２６の切換作用部５３に対応する箇所には、規制状態検出センサ２７の回動軸２７Ａに固定の検知アーム２７Ｂが備えられている。規制状態検出センサ２７は、例えば、規制部材２６が規制状態であることを検知するときはオン状態であり、規制部材２６が規制解除状態であることを検知するときはオフ状態となるスイッチ式センサにて構成されている。尚、検知状態に対応するオン状態とオフ状態とは逆の内容に設定するものでもよい。 As shown in FIGS. 7, 8 and 9, a detection arm 27B fixed to the rotating shaft 27A of the regulation state detection sensor 27 is provided at a position corresponding to the switching action portion 53 of the regulation member 26. The regulation state detection sensor 27 is, for example, an ON state when detecting that the regulation member 26 is in the regulation state, and an OFF state when detecting that the regulation member 26 is in the regulation release state. It is composed of. The on state and the off state corresponding to the detection state may be set to the opposite contents.

そして、規制部材２６を規制状態から規制解除状態に切り換えるに伴って、切換作用部５３が検知アーム２７Ｂに接当して規制状態検出センサ２７の回動軸２７Ａが回動してオン状態からオフ状態に切り換わる。規制状態検出センサ２７の回動軸２７Ａ及び検知アーム２７Ｂは、センサ内部の図示しない付勢機構によりオフ状態に回動付勢されている。 Then, as the regulation member 26 is switched from the regulation state to the regulation release state, the switching action portion 53 contacts the detection arm 27B and the rotation shaft 27A of the regulation state detection sensor 27 rotates to turn from the on state to the off state. Switch to the state. The rotation shaft 27A and the detection arm 27B of the regulation state detection sensor 27 are rotationally biased to the off state by a biasing mechanism (not shown) inside the sensor.

受止め台２５は、機体後部側端部が支持ブラケット４６の支持軸部４６Ｂに回動自在に支持されている。すなわち、受止め台２５は、規制部材２６の揺動軸芯と同一の機体前部側の横向き軸芯周りで揺動自在に支持ブラケット４６に支持されている。上記したように、規制状態にあるときは、図７，８に示すように、規制部材２６の基端側支持部２６ａに形成した係止部５５が受止め台２５の上面に接当しており、規制部材２６がコイルバネ５４の付勢力により下方に回動付勢されるので、受止め台２５も同様に下方に向けて回動付勢されている。又、受止め台２５は、内面側に設けられた当り部５６が下方側に位置する脱穀フィードチェーン１０の搬送始端部に作用する第２押え部材２９に接当してそれ以上の下方回動が規制される構成となっている。 The receiving platform 25 is rotatably supported by the support shaft portion 46B of the support bracket 46 at its rear end portion. That is, the receiving base 25 is supported by the support bracket 46 so as to be swingable around the same lateral axis on the front side of the machine body as the swing axis of the regulating member 26. As described above, when in the restricted state, as shown in FIGS. 7 and 8, the locking portion 55 formed on the base end side support portion 26a of the restriction member 26 contacts the upper surface of the receiving base 25. Since the regulating member 26 is urged to rotate downward by the urging force of the coil spring 54, the receiving base 25 is also urged to rotate downward. Further, the receiving base 25 contacts the second pressing member 29, which acts on the conveyance start end portion of the threshing feed chain 10 in which the contact portion 56 provided on the inner surface side is located on the lower side, and rotates further downward. Is regulated.

上記したように、センサ受け部４１から延長支持部４４が延設され、その延長支持部４４に支持ブラケット４６が連結されているので、第１押え部材２８及び第２押え部材２９は、横向き軸芯周りで揺動自在に支持ブラケット４６に支持される構成となっている。 As described above, since the extension support portion 44 is extended from the sensor receiving portion 41 and the support bracket 46 is connected to the extension support portion 44, the first pressing member 28 and the second pressing member 29 have the horizontal shafts. The support bracket 46 is swingably supported around the core.

図４に示すように、規制状態検出センサ２７の検出情報に基づいて、脱穀装置４の駆動速度を制御する脱穀制御部としての制御装置Ｈが備えられている。この制御装置Ｈは、規制状態検出センサ２７により規制部材２６が規制状態であることが検出されると刈取作業用の運転状態になり、規制状態検出センサ２７により規制部材２６が規制解除状態であることが検出されると枕扱ぎ用の運転状態になるように、脱穀装置４の駆動速度を制御するように構成されている。 As shown in FIG. 4, a control device H is provided as a threshing control unit that controls the drive speed of the threshing device 4 based on the detection information of the regulation state detection sensor 27. In the control device H, when the regulation state detection sensor 27 detects that the regulation member 26 is in the regulation state, the control device H enters the operating state for the mowing work, and the regulation state detection sensor 27 causes the regulation member 26 to be in the regulation release state. When this is detected, the drive speed of the threshing device 4 is controlled so as to enter the operation state for pillow handling.

具体的には、制御装置Ｈには規制状態検出センサ２７の検出情報が入力されており、又、制御装置Ｈは、図示しない燃料調節機構の作動を制御することができるように構成されている。そして、規制状態検出センサ２７の検出情報に基づいて、エンジン７に供給される燃料供給量を変更してエンジン７の出力回転速度を変更調節することにより、刈取作業用の運転状態と枕扱ぎ用の運転状態とに切り換えるよう構成されている。 Specifically, the detection information of the regulation state detection sensor 27 is input to the control device H, and the control device H is configured to be able to control the operation of a fuel adjustment mechanism (not shown). .. Then, based on the detection information of the regulation state detection sensor 27, the amount of fuel supplied to the engine 7 is changed to change and adjust the output rotation speed of the engine 7, whereby the operating state for mowing work and the pillow handling are performed. It is configured to switch to the operating state for use.

刈取作業用の運転状態では、エンジン７の出力回転数が定格回転数又はそれに近い高速で回転駆動する。そして、枕扱ぎ用の運転状態では刈取作業用の運転状態のときに比べて、脱穀装置４の駆動速度が低速になるように、エンジン７の出力回転数が定格回転数よりも低い回転数に調節される。このようにして、枕扱ぎ作業を行うときには、脱穀フィードチェーン１０を低速にて駆動することで手作業による穀稈供給が行い易くなるようにしている。 In the operating state for mowing work, the output rotation speed of the engine 7 is rotationally driven at a high speed close to or equal to the rated rotation speed. Then, the output speed of the engine 7 is lower than the rated speed so that the driving speed of the threshing device 4 becomes lower in the operating state for pillow handling than in the operating state for mowing work. Adjusted to. In this way, when the pillow handling work is performed, the threshing feed chain 10 is driven at a low speed to facilitate the manual feeding of the grain culms.
