The present invention relates to a combine threshing apparatus including a dust discharge path for discharging dust from a threshing machine body together with a sorting wind.

上記したコンバインの脱穀装置として、従来、例えば特許文献１に記載されたものがあった。特許文献１に記載されたものでは、排塵経路としての風力排塵経路を備え、風力排塵経路に排塵制御体を開き姿勢と閉じ姿勢とに揺動切換え自在に設け、排塵制御体と排ワラ搬送装置を構成する搬送ガイドレールの搬送終端側に連結された連結杆とを連動させる連動機構を備えて、搬送ガイドレールが無端回動チェーンに対して設定間隔以上離間するよう移動すると、排塵制御体が開き姿勢になり、搬送ガイドレールが無端回動チェーンに対して設定間隔未満に位置するよう移動すると、排塵制御体が閉じ姿勢になるよう構成されている。 Conventionally, for example, Patent Document 1 discloses a combine threshing apparatus described above.

選別部に選別処理するべく存在する処理物が少なくなると、穀粒が選別風によって塵埃と共に排塵経路から脱穀機体外に排出されやすくなる。この穀粒排出を防止するよう上記した従来の技術を採用しても、まだ改良すべき点があった。
つまり、従来の技術を採用した場合、排ワラ搬送装置の搬送終端部に検出センサを設け、排ワラ搬送装置の搬送終端部における脱穀排ワラのボリュームが小になったことを検出すると、排塵制御体を閉じ姿勢に切換え制御し、排ワラ搬送装置の搬送終端部における脱穀排ワラのボリュームが大になったことを検出すると、排塵制御体を開き姿勢に切換え制御することになり、脱穀排ワラが扱室から搬出されてから排ワラ搬送装置の搬送終端部までの搬送時間が経過した後に排塵制御体の開閉切換えが行なわれることになる。そして、刈取りを開始した後において扱室からの脱穀排ワラの搬出が始まると、選別部に脱穀処理物が既に供給されており、刈取りを中断や終了した後において扱室から搬出される脱穀排ワラが無くなると、選別部に残留する処理物が少なくなっていることから、排塵経路における排塵の規制や規制解除が選別部の処理物量の変化が発生した時から遅れて行なわれることになっていた。 When there are fewer processed objects to be sorted in the sorting unit, the grains are likely to be discharged out of the threshing machine from the dust discharge path together with dust by the sorting wind. Even if the above-described conventional technology was adopted to prevent this grain discharge, there was still a point to be improved.
In other words, when the conventional technology is adopted, a detection sensor is provided at the conveyance end of the waste straw conveying device, and when it is detected that the volume of the threshing waste straw at the conveyance termination of the waste straw conveying device is reduced, When the control body is controlled to be switched to the closed position and it is detected that the volume of the threshing drainer at the transfer terminal end of the waste straw transporting device has increased, the dust control body is switched to the open position and controlled. The dust control body is switched between open and close after the conveyance time from the discharge of the discharge wall to the transfer terminal of the discharge wall transfer device has elapsed. When the threshing waste straw is started to be carried out from the handling room after the cutting is started, the threshing processed material has already been supplied to the sorting unit, and the threshing waste discharged from the handling room after the cutting is interrupted or terminated. When there are no straws, there is less processed material remaining in the sorting section, so the regulation and release of dust in the dust path will be delayed after the change in the amount of processed material in the sorting section occurs. It was.

本発明の目的は、扱室から排出される脱穀排ワラを検出対象として排塵経路における排塵の規制や規制解除を行わせるものでありながら、選別部における処理物量の変化に迅速に対応させて排塵の規制や規制解除を行なわせることができるコンバインの脱穀装置を提供することにある。 The object of the present invention is to allow the threshing waste straw discharged from the handling room to be detected and to regulate or release the regulation of dust in the dust removal path, while promptly responding to changes in the amount of processed material in the sorting section. Therefore, an object of the present invention is to provide a combine threshing device that can control dust removal or cancel the regulation.

The waste wall conveying device comprises an endless rotating conveying chain and a sandwich conveying guide rail positioned along the endless rotating conveying chain,
The inheritance detection body is configured to be separated from the sandwiching conveyance guide rail so as to be detected and operated relative to the sandwiching conveyance guide rail.
The inheritance detection body is supported so as to be swingable up and down around an axial center disposed at a laterally inner portion of the conveying terminal portion of the threshing feed chain.

本第１、第２発明の構成によると、脱穀フィードチェーンによって扱室から脱穀排ワラが搬出されると、その脱穀排ワラが脱穀フィードチェーンから排ワラ搬送装置の搬送経路の始端部に受継がれてこの受継ぎを受継ぎ検出体が検出し、受継ぎ検出体の検出状態への切り換わりにより、排塵制御体が連係手段の作用によって開き姿勢に切り換わり、排塵経路が開かれて選別風及び塵埃の流出を容易にする。脱穀フィードチェーンによって扱室から搬出される脱穀排ワラが無くなると、排ワラ搬送装置の搬送経路の始端部に受継がれる脱穀排ワラが無くなって受継ぎ検出体が受継ぎを検出しなくなり、受継ぎ検出体の非検出状態への切り換わりにより、排塵制御体が連係手段の作用によって閉じ姿勢に切り換わり、排塵経路が閉じられて選別風及び塵埃を流出しにくくする。
つまり、脱穀排ワラが扱室から搬出されてからの経過時間が、扱室を出た脱穀排ワラが排ワラ搬送装置の搬送始端部まで搬送されるのに掛かる時間であって、排ワラ搬送装置の搬送終端部まで搬送されるのに掛かる時間よりも短い経過時間のうちに受継ぎ検出センサを作用させ、この結果を基に排塵制御体の開閉切換えを行なわせることができる。 According to the configuration of the first and second inventions , when the threshing waste straw is carried out of the handling chamber by the threshing feed chain, the threshing waste straw is inherited from the threshing feed chain to the start end of the conveying path of the waste straw conveying device. The inheritance detection body detects this inheritance, and when the inheritance detection body is switched to the detection state, the dust control body is switched to the open posture by the action of the linkage means, and the dust exhaust path is opened. Facilitates sorting air and dust outflow. When there is no threshing drainer carried out of the handling room by the threshing feed chain, there is no threshing drainer inherited at the start end of the transport path of the waste straw transporter, and the inheritance detector does not detect inheritance, By switching the joint detection body to the non-detection state, the dust control body is switched to the closed position by the action of the linkage means, and the dust discharge path is closed to make it difficult for the sorting wind and dust to flow out.
That is, the elapsed time after the threshing waste straw is carried out of the handling chamber is the time it takes for the threshing waste straw leaving the handling chamber to be transported to the transport start end of the waste straw transporting device, It is possible to cause the inheritance detection sensor to act within an elapsed time shorter than the time taken to transport the apparatus to the conveying terminal end, and to switch the dust control body on and off based on this result.

従って、刈取りが開始されて扱室から選別部に供給される処理物が多くなると、これに迅速に対応する状態で排塵制御体が開き姿勢に切換え操作されて排塵経路が選別風及び塵埃を流出させやすいように開き側になり、選別部に供給される処理物が多くても選別精度のよい選別処理を行わせることができ、畦際での旋回を行なうよう刈取り作業が中断されるとか刈取り作業が終了されるなど、扱室への刈取り穀稈の供給が無くなって選別部に存在する処理物が少なくなると、これに迅速に対応する状態で排塵制御体が閉じ姿勢に切換え操作されて排塵経路が選別風及び塵埃を流出しにくいように閉じ側になり、選別部に存在する処理物が少なくても穀粒が脱穀機体外に排出される穀粒損失を良好に防止できる。 Therefore, when cutting is started and the amount of processed material supplied from the handling chamber to the sorting unit increases, the dust control body is switched to the open position in a state of quickly responding to this, so that the dust path becomes the sorting wind and dust. The side is opened so that it can easily flow out, so that even if there is a large amount of processed material supplied to the sorting section, it is possible to perform sorting processing with high sorting accuracy, and the cutting operation is interrupted so as to turn at the shore. When there is no supply of harvested cereals to the handling room, such as when the harvesting operation is completed, and there is less processed material in the sorting section, the dust control body is switched to the closed position in a state that responds quickly to this. The dust path becomes closed so that the sorting wind and dust do not easily flow out, and it is possible to satisfactorily prevent the grain loss that the grain is discharged out of the threshing machine even if there is little processed material in the sorting unit. .

本第１、第２発明の構成によると、排ワラ搬送装置によって受継がれた脱穀排ワラの無端回動搬送チェーンと挟持搬送ガイドレールとによって挟持される稈身箇所とは異なる稈身箇所に受継ぎ検出体を作用させることができ、無端回動搬送チェーンと挟持搬送ガイドレールとによる挟持箇所には挟持圧のためにボリューム変化があまり発生せずとも、挟持箇所から外れた稈身箇所であってボリューム変化が発生しやすい稈身箇所に受継ぎ検出体を接触作用させて、受継ぎ検出体を精度よく反応させることができる。 According to the configuration of the first and second inventions , the slimming location is different from the slimming location that is sandwiched between the endless rotating conveyance chain and the clamping conveyance guide rail of the threshing drainer inherited by the waste straw conveying device. The inheritance detection body can be operated, and even if the volume change does not occur very much due to the clamping pressure at the clamping position by the endless rotating conveyance chain and the clamping conveyance guide rail, Therefore, the inheritance detection body can be caused to react with the slimming portion where the volume change is likely to occur, so that the inheritance detection body can be reacted accurately.

従って、稈身が軟質であるなど性状が種々異なる脱穀排ワラの場合でも、受継ぎ検出体を精度よく反応させて排塵制御体の切換えを適切に行なわせることができる。 Therefore, even in the case of a threshing and draining machine with different properties such as slimming, it is possible to cause the inheritance detection body to react accurately and to switch the dust control body appropriately.

受継ぎ検出体は、排ワラ搬送装置の搬送始端部に受継がれた脱穀排ワラに接触作用するものだから、脱穀フィードチェーンの搬送終端部付近に位置することになり、脱穀フィードチェーンによって搬送され、脱穀フィードチェーンの搬送終端部に近づいた脱穀排ワラが受継ぎ検出体に当接しやすくなる。本第２発明の構成によると、受継ぎ検出体を、脱穀フィードチェーンの搬送終端部の横内側箇所に配備された軸芯まわりに上下揺動自在に支持させてあるから、脱穀フィードチェーンによって搬送される脱穀排ワラが受継ぎ検出体に当接することがあっても、受継ぎ検出体は、当接した脱穀排ワラによる押圧を受けてスムーズに倒伏して当接した脱穀排ワラに対するストッパーになりにくい。 Since the inheriting detector is in contact with the threshing drainer handed over to the conveying start end of the waste straw conveying device, it is located near the conveying terminal end of the threshing feed chain and is conveyed by the threshing feed chain. The threshing drainer approaching the conveying terminal end of the threshing feed chain can easily come into contact with the inheritance detection body. According to the configuration of the second aspect of the invention, the inheritance detection body is supported by the threshing feed chain so as to be swingable up and down around the shaft center disposed at the laterally inner side of the conveyance terminal portion of the threshing feed chain. Even if the threshing waste straw that comes into contact with the inheritance detection body, the succession detection body is a stopper against the threshing drainer that has come down smoothly and pressed by the pressed threshing wastewall. Hard to become.

従って、受継ぎ検出体が排ワラ搬送装置の搬送始端部に受継がれた脱穀排ワラに接触作用するものでありながら、脱穀排ワラを受継ぎ検出体に起因する詰まりが生じないようにスムーズに搬送させることができる。 Therefore, the threshing drainer can be smoothly contacted with the threshing drainer handed over to the conveying start end of the waste straw conveying device so that the threshing drainer does not clog due to the inheriting detector. Can be conveyed.

本第３発明は、前記受継ぎ検出体を、前記軸芯まわりに上下揺動自在な基端側部と、平面視で前記基端側部から前記排ワラ搬送装置の搬送終端部に向かって延出する先端側部とを備えて構成してある。 According to the third aspect of the present invention, the inheritance detection body is moved from the base end side portion to the transport terminal end portion of the discharge wall transport apparatus in a plan view. And a distal end side portion that extends.

本第３発明の構成によると、受継ぎ検出体は、脱穀フィードチェーンによって搬送される脱穀排ワラが当接した場合、当接した脱穀排ワラによる押圧を受けて軸芯まわりにスムーズに倒伏して脱穀排ワラに対するストッパーになりにくいものでありながら、排ワラ搬送装置に受継がれた脱穀排ワラに対しては排ワラ搬送装置の搬送終端部に向かう先端側部によって接触作用し、この先端側部で脱穀排ワラによって受ける押圧によっても軸芯まわりにスムーズに倒伏して検出作用する。 According to the configuration of the third aspect of the present invention, when the threshing drainer conveyed by the threshing feed chain comes into contact, the inheritance detection body falls down smoothly around the shaft core under the pressure of the threshing drainer that comes into contact. Although it is difficult to become a stopper against the threshing drainer, the threshing drainer inherited by the drainer transporter is brought into contact with the tip side toward the transport end of the drainer transporter. Even by the pressure received by the threshing drainer at the side, the body smoothly falls down and acts on the axis.

従って、受継ぎ検出体の所定の検出作動をスムーズに行なわせて排塵制御体の切換えを応答性よく行なわせることができるのみならず、脱穀フィードチェーンによる脱穀排ワラの搬送も、排ワラ搬送装置による脱穀排ワラの搬送もスムーズに行わせることができる。 Accordingly, not only the predetermined detection operation of the inheritance detection body can be smoothly performed and the switching of the dust control body can be performed with high responsiveness, but also the transport of the threshing drainer by the threshing feed chain can be performed. It is possible to smoothly carry the threshing waste straw by the apparatus.

本第４発明は、前記受継ぎ検出体の先端側部を、前記脱穀フィードチェーンによって搬送される脱穀排ワラに当接作用する前側作用部と、前記排ワラ搬送装置に受継がれた脱穀排ワラに接触作用する後側作用部とを備えた上向きに凸の逆Ｖ字状に形成してある。 In the fourth aspect of the present invention, the tip side portion of the inheritance detection body is brought into contact with the threshing waste straw conveyed by the threshing feed chain, and the threshing waste inherited by the waste straw conveying device. It is formed in an upside-down inverted V-shape with a rear-side action portion that contacts the straw.

本第４発明の構成によると、受継ぎ検出体は、脱穀フィードチェーンによって搬送される脱穀排ワラに対しては前側作用部で当接して、当接した脱穀排ワラによる押圧を受けて軸芯まわりにスムーズに倒伏して脱穀排ワラに対するストッパーになりにくく、排ワラ搬送装置に受継がれた脱穀排ワラに対しては後側作用部で当接して、当接した脱穀排ワラによる押圧を受けて軸芯まわりにスムーズに倒伏して検出作用する。 According to the configuration of the fourth aspect of the present invention, the inheritance detecting body abuts on the threshing drainer conveyed by the threshing feed chain at the front side action portion, receives the pressure by the abutting threshing drainer, and receives the shaft core. The threshing drainer that has been smoothly laid down and is not likely to be a stopper for the threshing drainer, and is contacted by the rear working portion to the threshing drainer inherited by the drainer conveyor, In response, it falls down smoothly around the axis and acts as a detector.

本第５発明は、前記受継ぎ検出体の基端側部と前記排塵制御体とを、後端側ほど機体内側に位置するように斜めに傾斜した連動部材を介して連係してある。 In the fifth aspect of the invention, the base end side portion of the inheritance detection body and the dust control body are linked via an interlocking member that is inclined obliquely so that the rear end side is located on the inner side of the machine body.

本第５発明の構成によると、受継ぎ検出体が揺動自在に支持される箇所を脱穀フィードチェーンの搬送終端部に対して極力近い箇所に設置して、排ワラ搬送装置による脱穀排ワラの受継ぎが行なわれてから極力早期にその受継ぎの検出を行なえるようにしながら、連動部材の後端側を排塵制御体に対して機体横方向に極力近づけた状態で連係させて連係構造のコンパクト化を図ることができる。 According to the structure of this 5th invention, the location by which the inheritance detection body is supported so that rocking | fluctuation is possible is installed in the location as close as possible with respect to the conveyance termination part of a threshing feed chain, Linking structure with the rear end side of the interlocking member as close to the dust control body as close as possible in the lateral direction of the fuselage while enabling detection of the transfer as early as possible after the transfer Can be made compact.

従って、排ワラ搬送装置の脱穀排ワラの受継ぎの検出を極力早期に行なわせて排塵制御体の操作を応答性よく行なわせることができ、受継ぎ検出体と排塵制御体の連係をコンパクトに行なうことができる。 Accordingly, it is possible to detect the inheritance of the threshing waste wall of the waste wall conveying device as early as possible so that the operation of the dust control body can be performed with high responsiveness. It can be done compactly.

リターンばね６１は、制御体側の連動部材６５と、脱穀機体１０の横側壁１０ａの外面側に固定されたばね受け７２とに連結されており、制御体側の連動部材６５を下降側に引き付勢することにより、受継ぎ検出体５１を非検出状態（上昇姿勢）に揺動付勢し、かつ排塵制御体５０を下降閉じ姿勢に揺動付勢する。 The return spring 61 is connected to the control member-side interlocking member 65 and a spring receiver 72 fixed to the outer surface side of the lateral wall 10a of the threshing machine body 10, and pulls the control member-side interlocking member 65 downward. As a result, the inheritance detection body 51 is urged to swing in a non-detection state (upward position), and the dust removal control body 50 is oscillated and biased to a downward closed position.

従って、図４（ｂ）に示すように、連係手段６０は、脱穀フィードチェーン１２によって扱室１１から搬出された脱穀排ワラが排ワラ搬送装置４０の無端回動搬送チェーン４１の搬送始端部に受け継がれて受継ぎ検出体５１が検出状態に切り換わると、この切り換わりに伴って排塵制御体５０を上昇開き姿勢に切換え操作する。すなわち、受継ぎ検出体５１が検出状態に切り換わると、受継ぎ検出体５１の基端側部５１Ａが連動ピン６８を下向きに押圧操作して検出体側の連動部材６３の前端側が支軸６２の軸芯周り下降し、制御体側の連動部材６５が検出体側の連動部材６３の後端側によってリターンばね６１に抗して引き上げ操作され、操作アーム７０を上昇操作して排塵制御体５０を上昇開き姿勢に操作する。 Therefore, as shown in FIG. 4B, the linking means 60 is configured such that the threshing waste straw carried out of the handling chamber 11 by the threshing feed chain 12 is transferred to the transport start end portion of the endless rotating transport chain 41 of the waste straw transporter 40. When the inheritance is detected and the inheritance detection body 51 is switched to the detection state, the dust control body 50 is switched to the ascending open posture in accordance with the switching. That is, when the inheritance detection body 51 switches to the detection state, the proximal end side portion 51A of the inheritance detection body 51 pushes the interlocking pin 68 downward, and the front end side of the interlocking member 63 on the detection body side is the support shaft 62. The control member-side interlocking member 65 is pulled up against the return spring 61 by the rear end side of the detection member-side interlocking member 63, and the operating arm 70 is lifted to raise the dust control body 50. Operate to open position.

連係手段６０は、排ワラ搬送装置４０の無端回動搬送チェーン４１の搬送始端部における脱穀排ワラの受け継ぎが継続して行なわれて受継ぎ検出体５１が検出状態にあると、受継ぎ検出体５１が検出状態にある間、排塵制御体５０を上昇開き姿勢に維持する。 When the threshing drainer is continuously inherited at the conveyance start end portion of the endless rotating conveyance chain 41 of the end wall conveying device 40 and the inheritance detection body 51 is in the detection state, the linkage means 60 performs the inheritance detection body. While 51 is in the detection state, the dust control body 50 is maintained in the ascending open posture.

図４（ａ）に示すように、連係手段６０は、脱穀フィードチェーン１２によって扱室１１から搬出される脱穀排ワラが無くなり、排ワラ搬送装置４０の無端回動搬送チェーン４１の搬送始端部に受継がれる脱穀排ワラが無くなって受継ぎ検出体５１が非検出状態に切り換わると、この切り換わりに伴って排塵制御体５０を下降閉じ姿勢に切換え操作する。すなわち、受継ぎ検出体５１が非検出状態に切り換わると、制御体側の連動部材６５がリターンばね６１によって下げ操作され、操作アーム７０を下降操作して排塵制御体５０を下降閉じ姿勢に操作する。 As shown in FIG. 4 (a), the linking means 60 eliminates the threshing drainer carried out of the handling chamber 11 by the threshing feed chain 12, and is provided at the transport start end of the endless rotating transport chain 41 of the drainer transporter 40. When there is no threshing drainer to be inherited and the inheritance detection body 51 is switched to the non-detection state, the dust control body 50 is switched to the descending and closing posture along with this switching. That is, when the inheritance detection body 51 switches to the non-detection state, the interlock member 65 on the control body side is lowered by the return spring 61, and the operation arm 70 is lowered to operate the dust control body 50 in the lowered closed position. To do.
