JP 2007-6774 A

前記公知例は、排出用縦揚穀装置の揚穀螺旋と排出オーガの排出螺旋とを、接続メタルの連通口内を通した自在継ぎ手を介して接続しているので、連通口内に自在継ぎ手が存在する分搬送通路が狭くなって、穀粒排出に時間を要し、穀粒の排出作業の作業効率が低いという課題がある。
本発明は、接続メタル内の搬送通路を拡大するように工夫して、穀粒の排出作業の作業効率を向上させるようにしたものである。 In the above-mentioned known example, the sprouting helix of the vertical cerealing device for discharging and the discharging helix of the discharging auger are connected via a universal joint that passes through the connecting port of the connecting metal, so there is a universal joint in the connecting port. As a result, the conveyance path is narrowed, and it takes time to discharge the grain, and there is a problem that the work efficiency of the grain discharging operation is low.
The present invention is devised so as to enlarge the conveyance path in the connection metal to improve the work efficiency of the grain discharging operation.

排出用縦揚穀装置１５は揚穀螺旋３６により穀粒を揚穀し、揚穀送された穀粒は上部接続メタル１８の揚穀側接続メタル部１９の縦筒部２２に入り、縦筒部２２から連通口３２を通って排出オーガ１６に入り、排出螺旋３７により穀粒排出口３５へ搬送されて排出される。
排出用縦揚穀装置１５の揚穀螺旋３６の回転は、第１スプロケット４６からチェン４７により第２スプロケット４８に伝達され、第２スプロケット４８の回転が第２伝動軸５０を介して排出螺旋に伝達される。
こられの伝動機構Ｄの第１スプロケット４６とチェン４７と第２スプロケット４８と第２伝動軸５０は、前記連通口３２内を外して、揚穀側接続メタル部１９および排出側接続メタル部２１の周辺外部空間に設けているので、連通口３２内に回転伝達部材を設けずにすみ、連通口３２の開口部の全てが搬送通路となって、搬送通路を広くでき、搬送量を増加させて、穀粒の排出速度が高くなる。
本発明は、排出オーガ１６を接続した上部接続メタル１８の排出側接続メタル部２１の前後筒２５の軸心Ｓを、前記揚穀側接続メタル部１９の横筒部２３の軸心Ｙの高さ位置より低く配置したことを特徴とするコンバインとしたものであり、排出オーガ１６の穀粒排出口３５の上下動の回動中心となる揚穀側接続メタル部１９の軸心Ｙの高さ位置より排出オーガ１６に固定の上部接続メタル１８の排出側接続メタル部２１の前後筒２５の軸心Ｓの高さが低くなるように配置しているので、高い揚穀側接続メタル部１９から低い上部接続メタル１８の排出側接続メタル部２１の前後筒２５へ穀粒が流入するとき、穀粒の移動に重力を作用し、更に、連通口３２から排出オーガ１６の底部に移動する。
したがって、連通口３２の部分で穀粒が詰まるのを防止する。 In the present invention, a threshing device 3 is provided above a machine frame 1 provided with a traveling device 2 below, a reaping device 5 is provided in front of the threshing device 3, and a glen tank 11 is provided on the side of the threshing device 3.

On the side of the threshing device 3, a grain tank 11 is provided for temporarily storing the grain threshed by the threshing device 3 by supplying it with the lifting device 10. In the Glen tank 11, a spiral conveyance type discharging device 12 for discharging the grains in the Glen tank 11 is provided (FIG. 1).
The end of the discharge device 12 faces a connection metal 13 provided on the body frame 1 and is detachably engaged with a transmission shaft (not shown) provided in the connection metal 13 by so-called coupling joining.
A connection metal (connection member) 13 connects the discharge device 12 and the vertical cerealing device 15 for discharge. The base side of the discharge auger 16 is connected to the upper part of the vertical cerealing device 15 for discharge.
The terminal end (upper end) of the whipping cylinder 17 of the vertical cerealing device 15 for discharge and the base of the discharge auger 16 are connected by an upper connecting metal 18. The upper connection metal 18 is configured by a cereal side connection metal part 19 connected to the cereal cylinder 17 and a discharge side connection metal part 21 connected to the base of the discharge cylinder 20 of the discharge auger 16.

揚穀側接続メタル部１９は、前記排出用縦揚穀装置１５の揚穀筒１７に接続する縦筒部２２と、前記排出オーガ１６の排出側接続メタル部２１に接続する横筒部２３とを有し、縦筒部２２と横筒部２３の交差する部分には傾斜部２４を設ける。
排出側接続メタル部２１の形状は任意であるが、排出筒２０の軸心方向に長い前後筒２５の側部に接続筒２６を設けて構成している。
揚穀側接続メタル部１９の横筒部２３の揚穀側接合部３０には排出オーガ１６の排出側接続メタル部２１の接続筒２６に設けた排出側接合部３１を互いに当接させて回転のみ自在に取付け、揚穀側接合部３０と排出側接合部３１との部分に排出用縦揚穀装置１５と排出オーガ１６とを連通する連通口３２を形成する。
排出用縦揚穀装置１５で揚穀された穀粒は連通口３２から排出オーガ１６に流入し、排出オーガ１６の先端の穀粒排出口３５から排出され、穀粒排出口３５は排出用縦揚穀装置１５中心に旋回し、連通口３２の軸心を中心に上下回動するように構成する。 The cereal side connection metal part 19 includes a vertical cylinder part 22 connected to the cereal cylinder 17 of the vertical cerealing device 15 for discharge, and a horizontal cylinder part 23 connected to the discharge side connection metal part 21 of the discharge auger 16. An inclined portion 24 is provided at a portion where the vertical tube portion 22 and the horizontal tube portion 23 intersect.
Although the shape of the discharge side connection metal part 21 is arbitrary, the connection cylinder 26 is provided in the side part of the front-and-back cylinder 25 long in the axial center direction of the discharge cylinder 20.
The cereal side joint portion 30 of the horizontal tube portion 23 of the cereal side connection metal portion 19 is rotated by causing the discharge side joint portion 31 provided on the connection tube 26 of the discharge side connection metal portion 21 of the discharge auger 16 to contact each other. The communication port 32 which connects the vertical threshing device 15 for discharge | emission and the discharge auger 16 in the part of the cereal side junction part 30 and the discharge | emission side junction part 31 is formed freely.
The grain that has been harvested by the vertical cerealing device 15 for discharge flows into the discharge auger 16 from the communication port 32 and is discharged from the grain discharge port 35 at the tip of the discharge auger 16, and the grain discharge port 35 is discharged vertically. The cerealing device 15 is configured to turn around and rotate up and down around the axis of the communication port 32.

この場合、排出用縦揚穀装置１５の揚穀螺旋３６の回転を排出オーガ１６の排出螺旋３７に伝達して、排出オーガ１６を駆動するが、この伝動機構Ｄは、前記連通口３２内を外して、上部接続メタル１８の周辺外部空間に設ける。
そのため、連通口３２内に回転伝達部材を設けていないから、連通口３２の開口部の搬送通路を広くでき、搬送量を増加させて、穀粒排出作業の作業効率を向上させられる。
伝動機構Ｄを、連通口３２内を外して、上部接続メタル１８の周辺外部空間に設ける一例を示すと、前記揚穀側接続メタル部１９の傾斜部２４に取付部４０を設け、取付部４０に排出用縦揚穀装置１５の揚穀螺旋３６の揚穀軸４１を軸装する。
取付部４０内の揚穀軸４１の上端にはベベルギヤ４２を設け、ベベルギヤ４２にはベベルギヤ４３を噛み合わせ、ベベルギヤ４３は横方向の第１伝動軸４５の一端（排出オーガ１６側）に固定する。第１伝動軸４５の軸心は前記排出オーガ１６の先端が上下回動する回動中心に一致させて配置する。 In this case, the rotation of the threshing helix 36 of the vertical cerealing device 15 for discharging is transmitted to the discharging helix 37 of the discharging auger 16 to drive the discharging auger 16, and this transmission mechanism D passes through the communication port 32. It is removed and provided in the external space around the upper connection metal 18.
Therefore, since no rotation transmission member is provided in the communication port 32, the conveyance path of the opening of the communication port 32 can be widened, the conveyance amount can be increased, and the work efficiency of the grain discharging operation can be improved.
An example in which the transmission mechanism D is provided in the outer peripheral space of the upper connection metal 18 by removing the inside of the communication port 32 is provided with an attachment portion 40 on the inclined portion 24 of the cereal side connection metal portion 19. The cerealing shaft 41 of the cerealing helix 36 of the vertical cerealing device 15 for discharging is mounted.
A bevel gear 42 is provided at the upper end of the cerealing shaft 41 in the mounting portion 40, and the bevel gear 42 meshes with the bevel gear 42, and the bevel gear 43 is fixed to one end (the discharge auger 16 side) of the first transmission shaft 45 in the lateral direction. . The axis of the first transmission shaft 45 is arranged so as to coincide with the rotation center where the tip of the discharge auger 16 rotates up and down.

前記第１伝動軸４５の他端は、前記連通口３２とは反対側の揚穀側接続メタル部１９外に突出させて第１スプロケット４６を固定する。第１スプロケット４６にはチェン４７を掛け回し、チェン４７は第２スプロケット４８に掛け回し、第２スプロケット４８は前記第１伝動軸４５と並行な第２伝動軸５０の一端に固定する。
前記第２伝動軸５０は、排出オーガ１６の穀粒排出口３５に対して常時排出オーガ１６の基部側後方に位置させ、第２伝動軸５０の他端は排出側接続メタル部２１の前後筒２５の始端部（後端部）に設けた取付部５１に軸装する。取付部５１内の第２伝動軸５０にはベベルギヤ５２を設け、ベベルギヤ５２にはベベルギヤ５３を噛み合わせ、ベベルギヤ５３は排出オーガ１６の排出螺旋３７の螺旋軸５４の端部に固定する。 The other end of the first transmission shaft 45 protrudes outside the cereal side connection metal part 19 on the side opposite to the communication port 32 to fix the first sprocket 46. A chain 47 is hung on the first sprocket 46, the chain 47 is hung on a second sprocket 48, and the second sprocket 48 is fixed to one end of a second transmission shaft 50 parallel to the first transmission shaft 45.
The second transmission shaft 50 is always positioned on the rear side of the base side of the discharge auger 16 with respect to the grain discharge port 35 of the discharge auger 16, and the other end of the second transmission shaft 50 is the front and rear cylinders of the discharge side connection metal portion 21. It mounts on the attaching part 51 provided in the start end part (rear end part) of 25. A bevel gear 52 is provided on the second transmission shaft 50 in the mounting portion 51, and the bevel gear 53 is engaged with the bevel gear 52, and the bevel gear 53 is fixed to the end of the spiral shaft 54 of the discharge spiral 37 of the discharge auger 16.

したがって、排出用縦揚穀装置１５から排出オーガ１６への回転伝達する伝達機構Ｄは上部接続メタル１８の外側に配置したので、上部接続メタル１８の排出用縦揚穀装置１５と排出オーガ１６とを連通させる連通口３２および連通口３２を通る搬送路内に軸等が存在せず、上部接続メタル１８の連通口３２の開口部で形成される搬送通路を広くでき、搬送量を増加させて、穀粒排出時間を短縮して、穀粒排出作業の作業効率を向上させる。
しかして、排出用縦揚穀装置１５の揚穀螺旋３６の上端は、略揚穀筒１７の上端高さ位置に一致させ、揚穀側接続メタル部１９内の揚穀軸４１には連通口３２に向けて穀粒を飛ばす羽根体５５を設ける。
したがって、上部接続メタル１８の連通口３２内に伝達機構Ｄの伝動部材がなく、上部接続メタル１８内に羽根体５５を設けているので、上部接続メタル１８内に横向きの搬送螺旋が設けなくても、排出オーガ１６への引継は良好となる。 Therefore, since the transmission mechanism D for transmitting rotation from the vertical cerealing device 15 for discharging to the discharging auger 16 is disposed outside the upper connecting metal 18, the vertical threshing device 15 for discharging the upper connecting metal 18, the discharging auger 16, and the like. There is no shaft or the like in the communication path 32 that communicates with the communication port 32, and the conveyance path formed by the opening of the communication port 32 of the upper connection metal 18 can be widened to increase the conveyance amount. , Shorten the grain discharge time and improve the work efficiency of the grain discharge work.
Thus, the upper end of the cerealing helix 36 of the vertical cerealing device 15 for discharge is made to substantially coincide with the upper end height position of the cerealing cylinder 17 and is connected to the cerealing shaft 41 in the cerealing side connection metal part 19. A blade body 55 is provided to fly the grain toward 32.
Accordingly, there is no transmission member of the transmission mechanism D in the communication port 32 of the upper connection metal 18, and the blade body 55 is provided in the upper connection metal 18, so that a lateral conveying spiral is not provided in the upper connection metal 18. However, the transfer to the discharge auger 16 is good.

即ち、搬送の抵抗となる伝達機構Ｄが無いことにより連通口３２が広くなること、上部接続メタル１８の揚穀側接続メタル部１９内に羽根体５５を設けていること等の理由により、連通口３２部分での詰まり発生を防止して、排出用縦揚穀装置１５から排出オーガ１６への引継ぎを円滑・良好にして、穀粒排出作業の作業効率を向上させる。
しかして、排出オーガ１６を接続した上部接続メタル１８の排出側接続メタル部２１の前後筒２５の軸心Ｓは、前記揚穀側接続メタル部１９の横筒部２３の軸心Ｙの高さ位置より低くなるように、配置する（図５）。
即ち、前後筒２５は横筒部２３の軸心Ｙを中心に回動するため、略水平の排出オーガ１６の収納状態において、前後筒２５の軸心Ｓを揚穀側接続メタル部１９の横筒部２３の軸心Ｙの高さ位置より低くさせると、排出オーガ１６の穀粒排出口３５を上下させても、常時前後筒２５の軸心Ｓが揚穀側接続メタル部１９の横筒部２３の軸心Ｙの高さ位置より低くなる。 That is, the communication port 32 is widened due to the absence of the transmission mechanism D that serves as a conveyance resistance, and the blade body 55 is provided in the mashing-side connection metal portion 19 of the upper connection metal 18. Occurrence of clogging at the mouth 32 portion is prevented, the transfer from the vertical lifting cerealing device 15 to the discharge auger 16 is made smooth and good, and the work efficiency of the grain discharging operation is improved.
Thus, the axis S of the front and rear cylinders 25 of the discharge side connection metal part 21 of the upper connection metal 18 connected to the discharge auger 16 is the height of the axis Y of the horizontal cylinder part 23 of the cereal side connection metal part 19. It arrange | positions so that it may become lower than a position (FIG. 5).
That is, since the front and rear cylinders 25 rotate about the axis Y of the horizontal cylinder part 23, the axis S of the front and rear cylinders 25 is placed beside the cereal side connection metal part 19 in the storage state of the substantially horizontal discharge auger 16. If it is made lower than the height position of the axial center Y of the cylinder part 23, even if the grain discharge port 35 of the discharge auger 16 is moved up and down, the axial center S of the front and rear cylinders 25 is always the horizontal cylinder of the cereal side connection metal part 19. It becomes lower than the height position of the axial center Y of the part 23.

従来では、排出用縦揚穀装置１５と排出オーガ１６は略水平の横筒状のメタルで連結していたため、排出用縦揚穀装置１５で揚穀した穀粒は横方向に押し込むように搬送する構成であることから、排出用縦揚穀装置１５と排出オーガ１６との引継部分が詰まりの発生箇所となっていたが、本願では、排出オーガ１６の穀粒排出口３５の上下動の回動中心となる揚穀側接続メタル部１９の軸心Ｙの高さ位置より排出オーガ１６の基部の接続筒２６の軸心Ｓの高さが低くなるように配置し、高い揚穀側接続メタル部１９から低い排出オーガ１６の基部の接続筒２６へ穀粒を流入させ、引継を良好にして、穀粒排出作業の作業効率を向上させる。
即ち、高い揚穀側接続メタル部１９から低い排出オーガ１６の基部へ穀粒が移動するとき、穀粒の移動に重力が作用すると考えられ、上部接続メタル１８まで揚穀された穀粒はその自重を受けて排出用縦揚穀装置１５から排出オーガ１６へ引き継がれるので、上部接続メタル１８内で１６に向けて横方向に穀粒が移動するときに従来のように横向きの搬送螺旋の搬送力を作用させなくても、排出用縦揚穀装置１５と排出オーガ１６との引継部分での穀粒の停滞が抑制され、詰まり発生の防止効果が期待される合理的構成としている。 Conventionally, the vertical vertical cerealing device 15 for discharge and the discharge auger 16 are connected by a substantially horizontal horizontal cylindrical metal, so that the grains whipped by the vertical vertical cerealing device 15 for discharging are conveyed so as to be pushed in the horizontal direction. Because of this configuration, the takeover portion between the vertical cerealing device 15 for discharge and the discharge auger 16 has become a clogging occurrence location. Arranged so that the height of the shaft center S of the connecting cylinder 26 at the base of the discharge auger 16 is lower than the height of the axis Y of the whipping-side connection metal portion 19 as the moving center, and the higher mashing-side connection metal The grain is allowed to flow from the portion 19 to the connecting tube 26 at the base of the lower discharge auger 16 to improve the takeover and improve the work efficiency of the grain discharge operation.
That is, when the grain moves from the high cereal side connection metal part 19 to the base of the low discharge auger 16, it is considered that gravity acts on the movement of the grain, and the grain sown to the upper connection metal 18 is Since it is taken over from the vertical cerealing device 15 for discharge to the discharge auger 16 under its own weight, when the grain moves laterally toward the 16 in the upper connection metal 18, the conveyance of the horizontal conveyance spiral as in the conventional case is performed. Even if no force is applied, the stagnation of the grain at the succeeding portion of the vertical cerealing device 15 for discharge and the discharge auger 16 is suppressed, and a rational configuration is expected in which an effect of preventing clogging is expected.

更に、前記したように、連通口３２の部分には伝動軸が存在しないから、連通口３２の側方には排出オーガ１６の排出螺旋３７を臨ませることができ、連通口３２から排出オーガ１６内に流下する穀粒には直ちに排出螺旋３７の搬送力を作用させることができ、この点でも、詰まり発生を防止する。
この場合、排出オーガ１６は排出用縦揚穀装置１５の揚穀筒１７の軸心上方を外して排出用縦揚穀装置１５の揚穀筒１７の側方に位置させているので、揚穀側接続メタル部１９の臨む部分の排出オーガ１６の排出筒２０の軸心の高さを、常時揚穀側接続メタル部１９の横筒部２３の軸心位置より低くさせる構成を採用でき、この点でも、合理的構成となる。
即ち、排出用縦揚穀装置１５の揚穀筒１７の軸心直上方に、排出オーガ１６を配置すると、揚穀螺旋３６より更に上方の排出オーガ１６に穀粒を引き継くことになり、必ず、揚穀螺旋３６の搬送力の作用しない空間が生じるが、本願では、穀粒の自重移動という搬送力が得られて詰まり防止に貢献し、穀粒排出作業の作業効率を向上させる。 Further, as described above, since the transmission shaft does not exist in the communication port 32, the discharge spiral 37 of the discharge auger 16 can face the side of the communication port 32. The conveying force of the discharge spiral 37 can be immediately applied to the grain flowing down, and also in this respect, clogging is prevented.
In this case, since the discharge auger 16 is located on the side of the whipping cylinder 17 of the vertical vertical cerealing device 15 by removing the axial center upward of the whipping cylinder 17 of the vertical cerealing device 15 for discharging, A configuration in which the height of the axial center of the discharge cylinder 20 of the discharge auger 16 at the portion facing the side connection metal part 19 is always lower than the axial center position of the horizontal cylinder part 23 of the whipping side connection metal part 19 can be adopted. In that respect, it is a rational structure.
That is, when the discharge auger 16 is disposed immediately above the axis of the whipping cylinder 17 of the vertical cerealing device 15 for discharge, the grain is taken over to the discharge auger 16 further above the whipping spiral 36, Although a space where the conveying force of the cerealing helix 36 does not necessarily act is generated, in the present application, a conveying force of moving the weight of the grain is obtained, contributing to prevention of clogging, and improving the work efficiency of the grain discharging operation.

したがって、前記伝動構成による搬送通路の拡大化と排出オーガ１６の排出筒２０の高さ配置構成と相俟って、穀粒の詰まりを防止すると共に、穀粒排出時間の短縮が図れ、穀粒排出作業の作業効率を向上させられる。
また、排出オーガ１６から排出用縦揚穀装置１５への逆流を防止して穀粒排出効率を向上させて、穀粒排出時間を短縮し、穀粒排出作業の作業効率を向上させる。
しかして、前記上部接続メタル１８の排出側接続メタル部２１の接続筒２６の底面は、排出オーガ１６側が高く、揚穀側接続メタル部１９側を低くした傾斜面６０を有して形成する（図５）。また、揚穀側接続メタル部１９の横筒部２３の底面も排出オーガ１６側が高くが排出用縦揚穀装置１５の揚穀筒１７側が低くなる傾斜面６１に形成し、排出側接続メタル部２１の傾斜面６０と揚穀側接続メタル部１９の傾斜面６１とを略連続した同一傾斜面に形成し、仮に排出作業が終了したとき、排出側接続メタル部２１の傾斜面６０上の穀粒は傾斜面６０の傾斜および揚穀側接続メタル部１９の傾斜面６１の傾斜により揚穀筒１７に全て戻され、揚穀側接続メタル部１９および排出側接続メタル部２１内の残留穀粒の発生を防止し、清掃を容易にする。 Therefore, in combination with the enlargement of the conveyance path by the transmission structure and the height arrangement structure of the discharge cylinder 20 of the discharge auger 16, the clogging of the grain can be prevented and the grain discharge time can be shortened. The work efficiency of the discharge work can be improved.
Moreover, the backflow from the discharge auger 16 to the vertical lifting cerealing device 15 is prevented to improve the grain discharge efficiency, shorten the grain discharge time, and improve the work efficiency of the grain discharge work.
Thus, the bottom surface of the connection tube 26 of the discharge side connection metal portion 21 of the upper connection metal 18 is formed with an inclined surface 60 that is high on the discharge auger 16 side and low on the cereal side connection metal portion 19 side ( FIG. 5). Further, the bottom surface of the horizontal tube portion 23 of the cereal side connection metal portion 19 is also formed on the inclined surface 61 where the discharge auger 16 side is high but the flocculation tube 17 side of the vertical vertical cerealing device 15 is low, and the discharge side connection metal portion. The inclined surface 60 of 21 and the inclined surface 61 of the cereal side connection metal part 19 are formed on the substantially continuous same inclined surface, and when the discharging operation is temporarily finished, the grain on the inclined surface 60 of the discharge side connection metal part 21 The grains are all returned to the milling cylinder 17 by the inclination of the inclined surface 60 and the inclined surface 61 of the cereal side connection metal part 19, and the residual grains in the cereal side connection metal part 19 and the discharge side connection metal part 21. Prevents the occurrence of and facilitates cleaning.

即ち、排出オーガ１６の排出筒２０の底部は円弧面６２に形成し、円弧面６２と前記傾斜面６０との接続点Ａから円弧面６２側の穀粒は排出オーガ１６により全て排出され、円弧面６２と傾斜面６０との接続点Ａから揚穀筒１７側にある穀粒は上部接続メタル１８の傾斜面６０および傾斜面６１により全て揚穀筒１７に戻るので、上部接続メタル１８内には穀粒を残留させない。
また、排出用縦揚穀装置１５と排出オーガ１６との間の連通口３２の径は、揚穀筒１７および排出筒２０の内径より大径に形成する（図５）。
そのため、排出用縦揚穀装置１５から排出オーガ１６への引継が円滑・良好となり、排出時間を短縮し、穀粒の詰まり発生を防止し、穀粒排出作業の作業効率を向上させる。
しかして、排出オーガ１６の排出筒２０の基部側部分の側面には掃除口６５を開口させ、掃除口６５には蓋６６を着脱自在に取付ける。
掃除口６５は前記第１伝動軸４５の軸心線Ｔを含む排出筒２０の基部側部分の側面に開口させる。
即ち、平面視や背面視において、前記第１伝動軸４５の軸心線Ｔが掃除口６５と重なるように配置する。 That is, the bottom of the discharge cylinder 20 of the discharge auger 16 is formed on the circular arc surface 62, and the grains on the side of the circular arc surface 62 from the connection point A between the circular arc surface 62 and the inclined surface 60 are discharged by the discharge auger 16. All the grains on the side of the milling cylinder 17 from the connection point A between the surface 62 and the inclined surface 60 return to the milling cylinder 17 by the inclined surface 60 and the inclined surface 61 of the upper connecting metal 18, so Does not leave kernels.
Moreover, the diameter of the communication port 32 between the vertical threshing device 15 for discharge and the discharge auger 16 is formed to be larger than the inner diameters of the whipping tube 17 and the discharge tube 20 (FIG. 5).
Therefore, the takeover from the vertical cerealing device 15 for discharge to the discharge auger 16 becomes smooth and favorable, the discharge time is shortened, the occurrence of clogging of the grains is prevented, and the work efficiency of the grain discharge work is improved.
Accordingly, the cleaning port 65 is opened on the side surface of the base side portion of the discharge tube 20 of the discharge auger 16, and the lid 66 is detachably attached to the cleaning port 65.
The cleaning port 65 is opened on the side surface of the base side portion of the discharge tube 20 including the axial center line T of the first transmission shaft 45.
That is, it arrange | positions so that the axial center line T of the said 1st transmission shaft 45 may overlap with the cleaning port 65 in planar view or back view.

そのため、排出オーガ１６の掃除口６５から第１伝動軸４５までの上部接続メタル１８内の殆ど全てを見渡すことができ、残留穀粒の発見が容易となって、異種穀粒の混入発生を防止する。
しかして、前記揚穀側接続メタル部１９の取付部４０から突出する部分の第１伝動軸４５はチェンケース７０の基部に軸装する（図３、図８）。チェンケース７０内の第１伝動軸４５には前記第１スプロケット４６を固定する。
したがって、第１スプロケット４６およびチェン４７はチェンケース７０により包囲される。
チェンケース７０の基部は前記取付部４０側に回動自在に取付ける。チェンケース７０の先端には軸ケース７１の一端を取付け、軸ケース７１の他端は排出オーガ１６の取付部５１に取付ける。軸ケース７１は第２伝動軸５０を包囲する。
チェンケース７０は軸ケース７１により排出オーガ１６の穀粒排出口３５の上下に合わせて第１伝動軸４５中心に回動する。 Therefore, almost all the inside of the upper connection metal 18 from the cleaning port 65 of the discharge auger 16 to the first transmission shaft 45 can be looked over, and it becomes easy to find residual grains and prevent the occurrence of mixing of different kinds of grains. To do.
Thus, the portion of the first transmission shaft 45 protruding from the attachment portion 40 of the cereal side connection metal portion 19 is mounted on the base portion of the chain case 70 (FIGS. 3 and 8). The first sprocket 46 is fixed to the first transmission shaft 45 in the chain case 70.
Accordingly, the first sprocket 46 and the chain 47 are surrounded by the chain case 70.
A base portion of the chain case 70 is rotatably attached to the attachment portion 40 side. One end of the shaft case 71 is attached to the tip of the chain case 70, and the other end of the shaft case 71 is attached to the attachment portion 51 of the discharge auger 16. The shaft case 71 surrounds the second transmission shaft 50.
The chain case 70 is rotated about the first transmission shaft 45 by the shaft case 71 in accordance with the top and bottom of the grain discharge port 35 of the discharge auger 16.

チェンケース７０の基部にはステー７５の基部を取付け、ステー７５の先端と排出オーガ１６の排出筒２０との間に連結杆７６を設ける。連結杆７６には排出オーガ１６のオーガ上下シリンダ７７の一端を取付け、オーガ上下シリンダ７７の他端は排出用縦揚穀装置１５の所定位置に取付ける。
そのため、チェンケース７０はオーガ上下シリンダ７７のシリンダフレームＦの一部を構成し、チェンケース７０をカバー部材とフレーム構成との兼用部材とすることにより、構成を簡素にする。
即ち、チェンケース７０の一部とステー７５と連結杆７６と排出筒２０によりシリンダフレームＦを構成し、シリンダフレームＦによりオーガ上下シリンダ７７の支持およびオーガ上下シリンダ７７の保護を行い、しかも、チェンケース７０と軸ケース７１により排出オーガ１６の基部とも連結しているので、排出オーガ１６の支持構成の強度を向上させられる。
また、シリンダフレームＦとチェンケース７０と軸ケース７１によりオーガ上下シリンダ７７周辺を包囲するので、オーガ上下シリンダ７７の破損を防止する。 The base of the stay 75 is attached to the base of the chain case 70, and a connecting rod 76 is provided between the tip of the stay 75 and the discharge tube 20 of the discharge auger 16. One end of an auger upper / lower cylinder 77 of the discharge auger 16 is attached to the connecting rod 76, and the other end of the auger upper / lower cylinder 77 is attached to a predetermined position of the discharge vertical cerealing device 15.
Therefore, the chain case 70 constitutes a part of the cylinder frame F of the auger upper / lower cylinder 77, and the structure is simplified by using the chain case 70 as both a cover member and a frame structure.
That is, a part of the chain case 70, the stay 75, the connecting rod 76, and the discharge cylinder 20 constitute a cylinder frame F, and the cylinder frame F supports the auger upper and lower cylinders 77 and protects the auger upper and lower cylinders 77. Since the case 70 and the shaft case 71 are also connected to the base of the discharge auger 16, the strength of the support structure of the discharge auger 16 can be improved.
Further, since the periphery of the auger vertical cylinder 77 is surrounded by the cylinder frame F, the chain case 70, and the shaft case 71, the auger vertical cylinder 77 is prevented from being damaged.

しかして、前記揚穀側接続メタル部１９の所定位置にはオーガ高さ検出手段８０を設け、オーガ高さ検出手段８０の検出アーム８１には係合ピン８２を係合させる。係合ピン８２は別途設けたアーム８３に取付ける。アーム８３は基部を軸８４により揚穀側接続メタル部１９側に回動自在に取付け、アーム８３の先端には長孔８５を形成し、長孔８５に排出オーガ１６の排出筒２０に設けた取付軸８６を挿入して取付ける。
排出オーガ１６の穀粒排出口３５が上下すると、アーム８３の先端が排出オーガ１６の回動に連動して軸８４中心に上下回動し、アーム８３の回動により係合ピン８２は軸８４中心に円弧移動し、係合ピン８２の移動によりオーガ高さ検出手段８０の検出アーム８１が回動し、これによりオーガ高さ検出手段８０は穀粒排出口３５の高さ位置を検出する。
したがって、オーガ高さ検出手段８０は、穀粒排出口３５の上限および下限位置のみならず、上限位置と下限位置の間の穀粒排出口３５の高さ位置を正確に検出することができ、穀粒排出口３５の位置合わせを容易にし、排出作業全般の作業効率を向上させられる。
この場合、オーガ高さ検出手段８０はステー７５と排出筒２０との間に配置しているので、他の部材と干渉せずに取り付けられ、合理的な配置となる。
また、オーガ高さ検出手段８０はステー７５と排出筒２０の間の空間内にあるので、オーガ高さ検出手段８０と障害物との接触を避けられ、オーガ高さ検出手段８０の破損を防止する。 Thus, an auger height detection means 80 is provided at a predetermined position of the cereal side connection metal portion 19, and an engagement pin 82 is engaged with the detection arm 81 of the auger height detection means 80. The engaging pin 82 is attached to an arm 83 provided separately. The arm 83 is pivotally attached to the cereal side connecting metal part 19 side by a shaft 84, a long hole 85 is formed at the tip of the arm 83, and the long hole 85 is provided in the discharge cylinder 20 of the discharge auger 16. The mounting shaft 86 is inserted and mounted.
When the grain discharge port 35 of the discharge auger 16 moves up and down, the tip of the arm 83 rotates up and down around the shaft 84 in conjunction with the rotation of the discharge auger 16, and the engagement pin 82 rotates the shaft 84 by the rotation of the arm 83. The arc moves to the center, and the detection arm 81 of the auger height detection means 80 is rotated by the movement of the engagement pin 82, whereby the auger height detection means 80 detects the height position of the grain outlet 35.
Therefore, the auger height detecting means 80 can accurately detect not only the upper limit and lower limit positions of the grain outlet 35 but also the height position of the grain outlet 35 between the upper limit position and the lower limit position, The alignment of the grain discharge port 35 is facilitated, and the work efficiency of the whole discharge work can be improved.
In this case, since the auger height detecting means 80 is disposed between the stay 75 and the discharge cylinder 20, it can be attached without interfering with other members, resulting in a rational arrangement.
Further, since the auger height detection means 80 is in the space between the stay 75 and the discharge cylinder 20, contact between the auger height detection means 80 and the obstacle can be avoided, and damage to the auger height detection means 80 is prevented. To do.

（実施例の作用）
エンジンを始動し、走行装置２により機体を走行させ、刈取装置５で刈稈を刈取り、刈取った穀稈の穂先を脱穀装置３へ供給して脱穀する。
脱穀された穀粒は、グレンタンク１１に一時貯留され、一定量貯留されると、グレンタンク１１内の排出装置１２を作動させ、グレンタンク１１内の穀粒を排出する。 排出装置１２により搬送された穀粒は排出用縦揚穀装置１５により揚穀され、上部接続メタル１８の揚穀側接続メタル部１９内で連通口３２に向けて羽根体５５により跳ね飛ばされ、連通口３２から排出オーガ１６内に流下し、排出オーガ１６内の穀粒は排出螺旋３７により穀粒排出口３５まで搬送されて、排出オーガ１６により軽トラック等の所定のタンクに排出される。 (Operation of Example)
The engine is started, the vehicle is driven by the traveling device 2, the chopping device is cut by the reaping device 5, and the harvested culm tip is supplied to the threshing device 3 for threshing.
The threshed grain is temporarily stored in the Glen tank 11 and when a certain amount is stored, the discharging device 12 in the Glen tank 11 is operated to discharge the grain in the Glen tank 11. The grain transported by the discharging device 12 is whipped by the vertical whipping device 15 for discharging, and is spun off by the blade body 55 toward the communication port 32 in the mashing side connecting metal portion 19 of the upper connecting metal 18. It flows down into the discharge auger 16 from the communication port 32, the grain in the discharge auger 16 is conveyed to the grain discharge port 35 by the discharge spiral 37, and is discharged to a predetermined tank such as a light truck by the discharge auger 16.

この場合、排出用縦揚穀装置１５の揚穀螺旋３６の回転を排出オーガ１６の排出螺旋３７に伝達して、排出オーガ１６を駆動するが、排出用縦揚穀装置１５の揚穀螺旋３６の揚穀軸４１の上部は上部接続メタル１８の揚穀側接続メタル部１９の取付部４０に軸装し、取付部４０には排出オーガ１６と連通する連通口３２とは反対方向に突出する第１伝動軸４５を軸装し、揚穀軸４１と第１伝動軸４５とは取付部４０内のベベルギヤ４２とベベルギヤ４３により回転伝達し、連通口３２内には排出オーガ１６へ駆動伝達する伝達部材を設けていないから、排出用縦揚穀装置１５と排出オーガ１６を接続する上部接続メタル１８の連通口３２および連通口３２を通る搬送路内には軸等が存在せず、上部接続メタル１８の連通口３２の開口面積を広くして搬送通路を広くでき、搬送量を増加させて、穀粒排出時間を短縮し、排出作業全般の作業効率を向上させる。
また、排出オーガ１６の穀粒排出口３５は旋回および上下するため、単に、伝動機構を排出用縦揚穀装置１５および排出オーガ１６の外側に設けると複雑になるが、前記第１伝動軸４５の他端を、前記連通口３２とは反対側の排出用縦揚穀装置１５の上部接続メタル１８外に突出させて第１スプロケット４６を固定し、排出用縦揚穀装置１５の揚穀筒１７および排出オーガ１６の排出筒２０の外部空間に配置した第１スプロケット４６と第１スプロケット４６に荷掛回したチェン４７と第２スプロケット４８と第２伝動軸５０とにより、排出用縦揚穀装置１５の回転を排出オーガ１６に伝達するので、従来存在していた連通口３２内の排出オーガ１６への駆動伝達部材の省略を、簡単な構成で、実現する。 In this case, the rotation of the threshing spiral 36 of the vertical vertical cerealing device 15 is transmitted to the discharging spiral 37 of the discharging auger 16 to drive the discharging auger 16. The upper part of the cereal shaft 41 is mounted on the attachment part 40 of the cereal side connection metal part 19 of the upper connection metal 18, and the attachment part 40 protrudes in the opposite direction to the communication port 32 communicating with the discharge auger 16. The first transmission shaft 45 is mounted, and the cerealing shaft 41 and the first transmission shaft 45 are rotated and transmitted by the bevel gear 42 and the bevel gear 43 in the mounting portion 40, and are transmitted to the discharge port 16 in the communication port 32. Since no transmission member is provided, there is no shaft or the like in the communication port 32 of the upper connection metal 18 that connects the vertical vertical cerealing device 15 for discharge and the discharge auger 16 and the conveyance path that passes through the communication port 32, and the upper connection. Wide opening area of the communication port 32 of the metal 18 And it can widen the transport passage, by increasing the conveyance amount, and shorten the grain discharge time, improve the working efficiency of the discharge operations in general.
Further, since the grain outlet 35 of the discharge auger 16 turns and moves up and down, it is complicated if the transmission mechanism is simply provided outside the vertical lifting cerealing device 15 and the discharge auger 16, but the first transmission shaft 45 is complicated. The first sprocket 46 is fixed by projecting the other end of the first sprocket 46 out of the upper connecting metal 18 of the discharging vertical cerealing device 15 opposite to the communication port 32, and the cereal cylinder of the discharging vertical cerealing device 15 17 and the first sprocket 46 arranged in the outer space of the discharge cylinder 20 of the discharge auger 16, the chain 47 loaded around the first sprocket 46, the second sprocket 48, and the second transmission shaft 50, the vertical whipping for discharge Since the rotation of the device 15 is transmitted to the discharge auger 16, the omission of the drive transmission member to the discharge auger 16 in the communication port 32, which has existed conventionally, is realized with a simple configuration.

しかして、第１伝動軸４５から排出オーガ１６の排出螺旋３７への伝動は、排出オーガ１６の穀粒排出口３５とは反対側となる排出用縦揚穀装置１５の揚穀筒１７の周辺空間に第１伝動軸４５と並行の第２伝動軸５０を設け、第１伝動軸４５と第２伝動軸５０とに夫々第１スプロケット４６と第２スプロケット４８を固定し、第１スプロケット４６と第２スプロケット４８にチェン４７を掛け回し、第２伝動軸５０の他端を排出オーガ１６の取付部５１に軸装し、排出オーガ１６に固定の上部接続メタル１８の排出側接続メタル部２１の前後筒２５の外側の取付部５１内でベベルギヤ５２とベベルギヤ５３を噛み合わせて構成しているので、連通口３２には軸等の伝動部材を設けなくてすみ、第１伝動軸４５から排出オーガ１６の排出螺旋３７への伝動構成は上部接続メタル１８の外部空間に配置できる。   Thus, the transmission from the first transmission shaft 45 to the discharge spiral 37 of the discharge auger 16 is the periphery of the milling cylinder 17 of the vertical vertical cerealing device 15 for discharge that is opposite to the grain discharge port 35 of the discharge auger 16. A second transmission shaft 50 parallel to the first transmission shaft 45 is provided in the space, and the first sprocket 46 and the second sprocket 48 are fixed to the first transmission shaft 45 and the second transmission shaft 50, respectively. The chain 47 is wound around the second sprocket 48, the other end of the second transmission shaft 50 is mounted on the mounting portion 51 of the discharge auger 16, and the discharge side connection metal portion 21 of the upper connection metal 18 fixed to the discharge auger 16 is provided. Since the bevel gear 52 and the bevel gear 53 are engaged with each other in the mounting portion 51 outside the front and rear cylinders 25, it is not necessary to provide a transmission member such as a shaft at the communication port 32. 16 discharge spirals 3 Transmission structure for may be located outside the space of the upper connecting metal 18.

また、排出用縦揚穀装置１５の揚穀螺旋３６の回転を出力する第１伝動軸４５は、その軸心を、排出オーガ１６の穀粒排出口３５の上下回動中心に一致するように配置しているので、第１伝動軸４５から排出オーガ１６の排出側接続メタル部２１への伝動構成を、排出オーガ１６の穀粒排出口３５の上下動に支障がないように構成でき、合理的な構成にできる。
前記第１伝動軸４５から排出オーガ１６の排出螺旋３７への伝動構成のうちの第２伝動軸５０は、排出オーガ１６の穀粒排出口３５に対して上部接続メタル１８を中間に挟んで反対側となるように、揚穀筒１７の後側に位置させているから、排出オーガ１６の上下回動に支障が無く、合理的な配置となる。
しかして、排出オーガ１６に固定の上部接続メタル１８の排出側接続メタル部２１の前後筒２５の軸心Ｓは、前記揚穀側接続メタル部１９の横筒部２３の軸心Ｙの高さ位置より低くなるように配置しているので、高い上部接続メタル１８の連通口３２から低い排出オーガ１６の排出側接続メタル部２１の前後筒２５へ移動するので、良好に引き継がれる。 Further, the first transmission shaft 45 that outputs the rotation of the threshing spiral 36 of the vertical cerealing device 15 for discharge is arranged so that its axis coincides with the vertical rotation center of the grain discharge port 35 of the discharge auger 16. Since it is arranged, the transmission configuration from the first transmission shaft 45 to the discharge side connection metal portion 21 of the discharge auger 16 can be configured so as not to hinder the vertical movement of the grain discharge port 35 of the discharge auger 16 and is rational. It can be made a typical configuration.
Of the transmission structure from the first transmission shaft 45 to the discharge spiral 37 of the discharge auger 16, the second transmission shaft 50 is opposite to the grain outlet 35 of the discharge auger 16 with the upper connection metal 18 in the middle. Since it is located on the rear side of the whipping cylinder 17 so as to be on the side, there is no hindrance to the vertical rotation of the discharge auger 16, and a rational arrangement is obtained.
Thus, the axis S of the front and rear cylinders 25 of the discharge side connection metal part 21 of the upper connection metal 18 fixed to the discharge auger 16 is the height of the axis Y of the horizontal cylinder part 23 of the cereal side connection metal part 19. Since it arrange | positions so that it may become lower than a position, since it moves to the front-and-back cylinder 25 of the discharge side connection metal part 21 of the low discharge auger 16 from the communicating port 32 of the high upper connection metal 18, it succeeds favorably.

即ち、高い上部接続メタル１８の連通口３２から低い排出オーガ１６の排出側接続メタル部２１の前後筒２５へ移動する穀粒には重力が作用することが期待され、排出用縦揚穀装置１５からの搬送力に加えて穀粒が落ちるように排出オーガ１６に引き継がれる。
したがって、排出用縦揚穀装置１５と排出オーガ１６との引継部分での穀粒の詰まり発生を防止すると共に、穀粒排出時間の短縮が図れ、排出作業全般の作業効率を向上させる。
また、連通口３２の部分には排出オーガ１６の排出側接続メタル部２１の前後筒２５と交差する伝動軸が存在しないから、連通口３２の側方に排出オーガ１６の排出螺旋３７を臨ませることができ、連通口３２から排出オーガ１６内に流下する穀粒は直ちに排出螺旋３７の搬送力を受ける。
したがって、この点でも、伝動構成と排出オーガ１６の排出側接続メタル部２１の前後筒２５の高さ配置構成と相俟って、穀粒の詰まりを防止すると共に、穀粒排出時間の短縮が図れ、排出作業全般の作業効率を向上させる。 That is, it is expected that gravity will act on the grains moving from the communication port 32 of the high upper connection metal 18 to the front and rear cylinders 25 of the discharge side connection metal portion 21 of the low discharge auger 16. Is taken over by the discharge auger 16 so that the grains fall in addition to the conveying force from the.
Therefore, the occurrence of clogging of the grain at the takeover portion between the vertical cerealing device 15 for discharge and the discharge auger 16 can be prevented, the time for discharging the grain can be shortened, and the work efficiency of the whole discharging operation can be improved.
Further, since there is no transmission shaft that intersects with the front and rear cylinders 25 of the discharge side connection metal portion 21 of the discharge auger 16 at the portion of the communication port 32, the discharge spiral 37 of the discharge auger 16 faces the side of the communication port 32. The grain flowing down into the discharge auger 16 from the communication port 32 immediately receives the conveying force of the discharge spiral 37.
Therefore, also in this respect, coupled with the transmission configuration and the height arrangement configuration of the front and rear cylinders 25 of the discharge side connection metal portion 21 of the discharge auger 16, the clogging of the kernel is prevented and the time for discharging the kernel is shortened. Improve work efficiency of overall discharge work.

しかして、上部接続メタル１８の排出側接続メタル部２１の接続筒２６の底面は、排出オーガ１６側を高く、揚穀側接続メタル部１９側が低くなる傾斜面６０を有して形成し、揚穀側接続メタル部１９の横筒部２３の底面は排出オーガ１６側が高く排出用縦揚穀装置１５の揚穀筒１７の上部側が低くなる傾斜面６１に形成し、排出側接続メタル部２１の傾斜面６０と揚穀側接続メタル部１９の傾斜面６１とが略連続した同一傾斜面に形成しているから、排出作業が終了したとき排出側接続メタル部２１内の傾斜面６０上の穀粒は傾斜面６０の傾斜および揚穀側接続メタル部１９の傾斜面６１の傾斜により揚穀筒１７に全て戻され、揚穀側接続メタル部１９および排出側接続メタル部２１内には穀粒が残留しない。
そのため、作業終了後、清掃等のメンテナンス作業を容易にし、排出作業全般の作業効率を向上させる。 Thus, the bottom surface of the connection tube 26 of the discharge side connection metal portion 21 of the upper connection metal 18 is formed with an inclined surface 60 that is higher on the discharge auger 16 side and lower on the cereal side connection metal portion 19 side. The bottom surface of the horizontal tube portion 23 of the cereal side connection metal portion 19 is formed on an inclined surface 61 where the discharge auger 16 side is high and the upper side of the cereal tube 17 of the vertical vertical cerealing device 15 is low. Since the inclined surface 60 and the inclined surface 61 of the cereal side connecting metal portion 19 are formed on the same inclined surface that is substantially continuous, the grain on the inclined surface 60 in the discharging side connecting metal portion 21 when the discharging operation is completed. The grains are all returned to the milling cylinder 17 by the inclination of the inclined surface 60 and the inclination of the inclined surface 61 of the whipped-side connection metal part 19, and the grains are placed in the whipped-side connection metal part 19 and the discharge-side connecting metal part 21. Does not remain.
Therefore, after the work is completed, maintenance work such as cleaning is facilitated, and the work efficiency of the discharge work is improved.

しかして、排出用縦揚穀装置１５と排出オーガ１６との間の連通口３２の径は、揚穀筒１７および排出筒２０の内径より大径に形成しているから、排出用縦揚穀装置１５から排出オーガ１６への引継が円滑・良好となり、排出時間を短縮し、穀粒の詰まり発生を防止し、排出作業全般の作業効率を向上させる。
しかして、排出オーガ１６の排出筒２０の基部側部分の側面には掃除口６５を開口させ、掃除口６５には蓋６６を着脱自在に取付け、平面視や背面視において、第１伝動軸４５の軸心線Ｔを掃除口６５と重なるように配置しているので、蓋６６を外すと、排出オーガ１６の掃除口６５から第１伝動軸４５までの上部接続メタル１８内の略全てを見渡すことができ、残留穀粒の発見が容易となって、異種穀粒の混入発生を防止する。
しかして、揚穀側接続メタル部１９の取付部４０から突出する部分の第１伝動軸４５はチェンケース７０の基部に軸装し、チェンケース７０の基部は取付部４０側に回動自在に取付け、チェンケース７０の先端には軸ケース７１の一端を取付け、軸ケース７１の他端は排出オーガ１６の取付部５１に取付けているから、チェンケース７０は軸ケース７１により排出オーガ１６の穀粒排出口３５の上下に合わせて第１伝動軸４５中心に回動する。 Therefore, the diameter of the communication port 32 between the vertical cerealing device 15 for discharge and the discharge auger 16 is formed to be larger than the inner diameters of the whipping tube 17 and the discharge tube 20, so The transfer from the device 15 to the discharge auger 16 becomes smooth and good, shortens the discharge time, prevents clogging of grains, and improves the work efficiency of the discharge work in general.
Thus, the cleaning port 65 is opened on the side surface of the base portion side portion of the discharge tube 20 of the discharge auger 16, and the lid 66 is detachably attached to the cleaning port 65, and the first transmission shaft 45 in plan view and rear view. Is disposed so as to overlap the cleaning port 65, so when the cover 66 is removed, the entire upper connecting metal 18 from the cleaning port 65 of the discharge auger 16 to the first transmission shaft 45 is overlooked. This makes it easier to find residual grains and prevents the occurrence of mixed grains.
Thus, the first transmission shaft 45 of the portion protruding from the attachment portion 40 of the cereal side connection metal portion 19 is mounted on the base portion of the chain case 70, and the base portion of the chain case 70 is rotatable to the attachment portion 40 side. Since one end of the shaft case 71 is attached to the tip of the chain case 70 and the other end of the shaft case 71 is attached to the attachment portion 51 of the discharge auger 16, the chain case 70 is attached to the grain of the discharge auger 16 by the shaft case 71. It rotates about the 1st transmission shaft 45 according to the upper and lower sides of the grain discharge port 35.

チェンケース７０の基部にはステー７５の基部を取付け、ステー７５の先端と排出オーガ１６の排出筒２０との間に排出オーガ１６のオーガ上下シリンダ７７の一端を取付けた連結杆７６を設けているから、チェンケース７０はオーガ上下シリンダ７７のシリンダフレームＦの一部を構成し、チェンケース７０をカバー部材とフレーム構成との兼用部材とすることにより、構成を簡素にする。
また、チェンケース７０の一部とステー７５と連結杆７６と排出筒２０によりシリンダフレームＦを構成しているから、シリンダフレームＦによりオーガ上下シリンダ７７の支持およびオーガ上下シリンダ７７の保護を行える。
また、軸ケース７１によりチェンケース７０は排出オーガ１６の基部とも連結しているので、排出筒２０とチェンケース７０と軸ケース７１と上部接続メタル１８とにより平面視略四角のボックス形状になり、排出オーガ１６の支持構成の強度を向上させる。 A base of the stay 75 is attached to the base of the chain case 70, and a connecting rod 76 is provided between one end of the auger upper and lower cylinders 77 of the discharge auger 16 between the tip of the stay 75 and the discharge cylinder 20 of the discharge auger 16. Therefore, the chain case 70 constitutes a part of the cylinder frame F of the auger upper and lower cylinders 77, and the chain case 70 is used as a member for both the cover member and the frame configuration, thereby simplifying the configuration.
In addition, since a part of the chain case 70, the stay 75, the connecting rod 76, and the discharge cylinder 20 constitute the cylinder frame F, the cylinder frame F can support the auger upper / lower cylinder 77 and protect the auger upper / lower cylinder 77.
Further, since the chain case 70 is also connected to the base of the discharge auger 16 by the shaft case 71, the discharge tube 20, the chain case 70, the shaft case 71, and the upper connection metal 18 form a substantially square box shape in plan view. The strength of the support structure of the discharge auger 16 is improved.

また、シリンダフレームＦとチェンケース７０と軸ケース７１によりオーガ上下シリンダ７７周辺を包囲するので、オーガ上下シリンダ７７の破損を防止する。
また、オーガ上下シリンダ７７の伸縮により連結杆７６が第１伝動軸４５中心に上下回動し、連結杆７６の上下に連動して第１伝動軸４５中心に第２伝動軸５０が連結杆７６と反対方向に上下回動する。
そして、図示は省略するが、排出用縦揚穀装置１５の揚穀筒１７を回転させることにより排出オーガ１６を旋回させるが、シリンダフレームＦとチェンケース７０と軸ケース７１は、排出オーガ１６と共に旋回する。
なお、前記した各実施例は、理解を容易にするために、個別または混在させて図示、あるいは説明しているが、これらは夫々種々組合せ可能であり、これらの表現によって、構成・作用等が限定されるものではなく、また、相乗効果を奏する場合も勿論存在する。 Further, since the periphery of the auger vertical cylinder 77 is surrounded by the cylinder frame F, the chain case 70, and the shaft case 71, the auger vertical cylinder 77 is prevented from being damaged.
Further, the expansion and contraction of the auger vertical cylinder 77 causes the connecting rod 76 to rotate up and down around the first transmission shaft 45, and the second transmission shaft 50 is connected to the center of the first transmission shaft 45 in conjunction with the vertical movement of the connecting rod 76. It rotates up and down in the opposite direction.
And although illustration is abbreviate | omitted, although the discharge auger 16 is rotated by rotating the whipping cylinder 17 of the vertical threshing apparatus 15 for discharge, the cylinder frame F, the chain case 70, and the shaft case 71 are together with the discharge auger 16. Turn.
Each of the above-described embodiments is illustrated or described separately or mixed for easy understanding, but these can be combined in various ways, and the expression, configuration, action, etc. It is not limited, and there are of course cases where a synergistic effect is obtained.
