Although not shown in the drawing cerealing device 13 and the discharging auger 14, a grain conveying spiral is provided, and the grains in the glen tank 5 are discharged out of the machine by the discharging cerealing device 13 and the discharging auger 14. .

前記排出オーガ１４は、起立状態の排出用揚穀装置１３の上部に横軸１５により回動自在に取付け、排出作業をしないときは排出用揚穀装置１３に対して折り曲げるように横軸１５中心に回動させ、回動させると排出オーガ１４の先端排出部１４Ａが上向きになって格納する。
したがって、排出オーガ１４の先端排出部１４Ａから穀粒が零れるのを防止できる。
そして、排出作業のときは、排出オーガ１４を横軸１５中心に回動させて、排出用揚穀装置１３と一直線状態となるように排出用揚穀装置１３に接続し、この状態で、排出用揚穀装置１３を前記接続メタル１２の軸心中心に横軸回動させ、排出用揚穀装置１３および排出オーガ１４を側方に倒して排出作業を行う。 The discharge auger 14 is pivotally attached to the upper part of the standing whipping cerealing device 13 by a horizontal shaft 15 and is centered on the horizontal shaft 15 so as to be bent with respect to the grouting device 13 for discharging when the discharging operation is not performed. The tip discharge portion 14A of the discharge auger 14 is turned upward and stored.
Therefore, it is possible to prevent the grains from spilling from the tip discharge portion 14 </ b> A of the discharge auger 14.
During the discharging operation, the discharging auger 14 is rotated about the horizontal axis 15 and connected to the discharging cerealing device 13 so as to be in a straight line with the discharging cerealing device 13. The cerealing device 13 is rotated about the axis of the connecting metal 12 in the horizontal direction, and the discharging cerealing device 13 and the discharging auger 14 are tilted sideways to perform the discharging operation.

なお、排出用揚穀装置１３と排出オーガ１４が直線状態になると、内部で排出用揚穀装置１３と排出オーガ１４の搬送螺旋が接続され、一体回転作動するように構成しているが、この具体的連結構成は公知であり、省略する。
前記排出オーガ１４の先端には、シュータ１６を設ける（図４）。シュータ１６は、弾性を有する合成樹脂により所謂「蛇腹」形状に伸縮および曲げ変形自在に形成し、シュータ１６の下端は自由端にして穀粒排出口１７を形成する。シュータ１６は排出オーガ１４の先端に回動自在に取付け、排出用揚穀装置１３および排出オーガ１４を傾倒させたとき、常時自重によりシュータ１６の先端が下方に位置するように構成する。 In addition, when the discharging cerealing device 13 and the discharging auger 14 are in a straight line state, the conveying spirals of the discharging cerealing device 13 and the discharging auger 14 are connected to each other and are configured to rotate integrally. The specific connection configuration is known and will be omitted.
A shooter 16 is provided at the tip of the discharge auger 14 (FIG. 4). The shooter 16 is formed of elastic synthetic resin in a so-called “belly bellows” shape so as to be stretchable and bendable. The shooter 16 has a lower end as a free end to form a grain discharge port 17. The shooter 16 is rotatably attached to the tip of the discharge auger 14, and is configured such that the tip of the shooter 16 is always positioned downward by its own weight when the cerealing device 13 and the discharge auger 14 are tilted.

しかして、グレンタンク５の後側上部には、後方に膨出する後側膨出部２０を形成する。後側膨出部２０は排出用揚穀装置１３より内側（脱穀装置３側）に所定間隔を置いて膨出縦面２１が位置して、平面視、前記排出用揚穀装置１３より脱穀装置３側のグレンタンク５の部分がカッター７の上方に膨出するように形成すると共に、側面視、後側膨出部２０の底面２２を前側に至るに従い低くなるように前下がりに傾斜させて形成する。
したがって、穀粒排出時のブリッジ現象を防止し、カッター７の上方空間を有効に利用してグレンタンク５の容量を増加させることができる。 Thus, a rear bulging portion 20 that bulges rearward is formed in the upper rear portion of the Glen tank 5. The rear side bulging part 20 is located at a predetermined interval on the inner side (the threshing device 3 side) from the cerealing device 13 for discharging, and the swelling vertical surface 21 is positioned. A portion of the 3rd side Glen tank 5 is formed so as to bulge above the cutter 7, and the bottom surface 22 of the rear side bulging portion 20 is inclined forward and downward so as to become lower as viewed from the side. Form.
Therefore, the bridge phenomenon at the time of grain discharge | emission can be prevented, and the capacity | capacitance of the glen tank 5 can be increased using the upper space of the cutter 7 effectively.

しかして、前記接続メタル１２の下部には掃除口２５を設け（図５、図６）、掃除口２５は走行装置２のクローラ２６の後面より後方に配置する。
したがって、接続メタル１２の清掃作業がクローラ２６に邪魔されずに行えて、容易になるばかりでなく、接続メタル１２の清掃作業時にクローラ２６上に穀粒が落下して散乱することもないので、この点でも、接続メタル１２の清掃作業を容易にする。
また、接続メタル１２に掃除口２５を設けているので、稲と麦、収穫穀粒の品種が相違するとき、あるいは、シーズンオフのとき等には掃除口２５から接続メタル１２内を清掃する。
２７は前記掃除口２５を閉塞する蓋であり、蓋２７はボルト２８により着脱自在に取付ける。 Accordingly, a cleaning port 25 is provided in the lower part of the connection metal 12 (FIGS. 5 and 6), and the cleaning port 25 is disposed behind the rear surface of the crawler 26 of the traveling device 2.
Therefore, the cleaning work of the connection metal 12 can be performed without being disturbed by the crawler 26, and not only is easy, but also the grains are not dropped and scattered on the crawler 26 during the cleaning work of the connection metal 12. This also facilitates the cleaning work of the connection metal 12.
Further, since the cleaning port 25 is provided in the connection metal 12, the inside of the connection metal 12 is cleaned from the cleaning port 25 when the varieties of rice, wheat and harvested grains are different, or when the season is off.
A lid 27 closes the cleaning port 25, and the lid 27 is detachably attached by a bolt 28.

しかして、グレンタンク５の後壁１１は、排出装置１０より所定高さ部分より下方に至るに従い前側に位置させて前下がりの下部後壁傾斜面３０を形成し、下部後壁傾斜面３０に続く後壁１１は略垂直な下部後壁縦面３１に形成し、下部後壁縦面３１に接続メタル１２を接続する。
したがって、後壁１１の後方に位置する排出用揚穀装置１３と下部後壁縦面３１との間に空間部３２が形成され、この空間部３２にブレーキ装置３５を設ける。
ブレーキ装置３５の一例を示すと（図７、図８、図９）、接続メタル１２にステー３６を固定し、ステー３６には移動溝３７を形成する。移動溝３７には軸３８を取付け、軸３８にはステー３６を挟持するようにブレーキシュー３９を取付ける。軸３８にはアーム４０を取付け、アーム４０にはカム４１を取付け、カム４１は前記ブレーキシュー３９をステー３６に押し付ける。 Thus, the rear wall 11 of the Glen tank 5 is positioned at the front side from the discharge device 10 below the predetermined height portion to form a lower rear wall inclined surface 30 that is forwardly lowered, and is formed on the lower rear wall inclined surface 30. The subsequent rear wall 11 is formed in a substantially vertical lower rear wall vertical surface 31, and the connection metal 12 is connected to the lower rear wall vertical surface 31.
Therefore, a space portion 32 is formed between the discharging cerealing device 13 located behind the rear wall 11 and the lower rear wall vertical surface 31, and a brake device 35 is provided in the space portion 32.
As an example of the brake device 35 (FIGS. 7, 8, and 9), a stay 36 is fixed to the connection metal 12, and a moving groove 37 is formed in the stay 36. A shaft 38 is attached to the moving groove 37, and a brake shoe 39 is attached to the shaft 38 so as to sandwich the stay 36. An arm 40 is attached to the shaft 38, a cam 41 is attached to the arm 40, and the cam 41 presses the brake shoe 39 against the stay 36.

アーム４０にはバネ４２を設け、バネ４２はブレーキシュー３９がステー３６をロックするように付勢する。バネ４２には操作部材４３を取付ける。操作部材４３を操作してアーム４０を回動させると、カム４１はブレーキシュー３９をステー３６から離脱させてアンロック状態となり、排出用揚穀装置１３が回動可能になって、排出用揚穀装置１３を回動させて所定任意位置で操作部材４３を戻すと、ブレーキシュー３９がステー３６をロックして排出用揚穀装置１３をその位置で保持する。
４５は排出用揚穀装置１３の回動を補助するダンパーである。
下部後壁傾斜面３０は、グレンタンク５内の穀粒を排出装置１０への誘導を円滑・確実にするだけでなく、下部後壁傾斜面３０により接続メタル１２周辺に空間部３２を形成し、ブレーキ装置３５をコンパクトに配置構成することができる。 The arm 40 is provided with a spring 42, and the spring 42 urges the brake shoe 39 to lock the stay 36. An operation member 43 is attached to the spring 42. When the operating member 43 is operated to rotate the arm 40, the cam 41 disengages the brake shoe 39 from the stay 36 and enters an unlocked state. When the grain device 13 is rotated and the operation member 43 is returned at a predetermined arbitrary position, the brake shoe 39 locks the stay 36 and holds the discharging grain raising device 13 at that position.
45 is a damper that assists the rotation of the cerealing device 13 for discharging.
The lower rear wall inclined surface 30 not only facilitates and reliably guides the grains in the grain tank 5 to the discharge device 10, but also forms a space portion 32 around the connection metal 12 by the lower rear wall inclined surface 30. The brake device 35 can be arranged and configured in a compact manner.

しかして、グレンタンク５の内側壁面４８には、脱穀装置３により脱穀した穀粒を供給揚穀する供給揚穀装置４９の上部を接続する（図１０）。供給揚穀装置４９の上部には内側壁面４８に形成したタンク供給口５０を包囲するケース５１を設ける。ケース５１は供給揚穀装置４９の円筒状の揚穀筒５２の上部に固定され、ケース５１内の前側には供給揚穀装置４９の揚穀螺旋（図示省略）の上部に設けた拡散翼５３の軌跡に合わせた円弧状の円弧ガイド部５４を設け、ケース５１の後側は平面視内側壁面４８に接近するに従い後側に位置するように傾斜させた傾斜ガイド部５５に形成する。
したがって、傾斜ガイド部５５により供給揚穀装置４９から供給された穀粒をグレンタンク５内の後方の後側膨出部２０から穀粒が溜って充填率を向上させることができる。 Therefore, the upper part of the supply cerealing device 49 for supplying and cerealing the grain threshed by the threshing device 3 is connected to the inner wall surface 48 of the Glen tank 5 (FIG. 10). A case 51 surrounding the tank supply port 50 formed in the inner wall surface 48 is provided on the upper part of the supply cerealing device 49. The case 51 is fixed to the upper part of the cylindrical whipping cylinder 52 of the supply cerealing device 49, and the diffusion blade 53 provided on the upper side of the cerealing helix (not shown) of the supply cerealing device 49 on the front side in the case 51. An arcuate arc guide portion 54 is provided in accordance with the locus, and the rear side of the case 51 is formed as an inclined guide portion 55 that is inclined so as to be positioned on the rear side as approaching the inner wall surface 48 in plan view.
Accordingly, the grains supplied from the supply cerealing device 49 by the inclined guide part 55 can be accumulated from the rear rear bulging part 20 in the Glen tank 5 to improve the filling rate.

即ち、ケース５１の傾斜ガイド部５５の部分を、仮に、内側壁面４８に直交するように当接させると、拡散翼５３が跳ね飛ばす穀粒の軌跡が前寄りになってしまうが、傾斜ガイド部５５は内側壁面４８に直交する線に対して後退角を有するように傾斜させているから、拡散翼５３が跳ね飛ばす穀粒の軌跡を後寄りにして、グレンタンク５内の後方から充填させる作用を奏する。また、拡散翼５３が跳ね飛ばした穀粒が傾斜ガイド部５５に当たって反射して飛ぶ角度も後寄りになる作用も期待できる。   That is, if the portion of the inclined guide portion 55 of the case 51 is brought into contact with the inner wall surface 48 so as to be orthogonal, the trajectory of the grain that the diffusion blade 53 jumps off becomes forward, but the inclined guide portion Since 55 is inclined so as to have a receding angle with respect to a line perpendicular to the inner wall surface 48, the locus of the grain that the diffusion blade 53 jumps off is moved backward, and filling is performed from the rear in the Glen tank 5. Play. Moreover, the effect | action which the grain which the spreading | diffusion wing | blade 53 jumped off hits the inclination guide part 55, is reflected, and flies back is also expectable.

しかして、図１１、図１２は、グレンタンク５の平面形状に関する他の実施例を示し、供給揚穀装置４９より後側の内側壁面４８を脱穀装置３側に膨出させて内側膨出部５８に形成する。内側膨出部５８は、後側に至に従い脱穀装置３に接近する内側前側傾斜面５９と後側に至に従い脱穀装置３より離れる内側後側傾斜面６０を有して形成し、内側前側傾斜面５９に供給揚穀装置４９のケース５１を接続する。
したがって、脱穀装置３とグレンタンク５の間に設けた空間の内の供給揚穀装置４９よりも後側の空間に内側膨出部５８を位置させることができ、空間を有効利用してグレンタンク５の容積を増加させることができる。
６１は内側膨出部５８の底面である。 11 and 12 show another embodiment relating to the planar shape of the Glen tank 5, and the inner wall surface 48 on the rear side from the supply cerealing device 49 is bulged toward the threshing device 3 so that the inner bulging portion can be seen. 58. The inner bulging portion 58 has an inner front inclined surface 59 that approaches the threshing device 3 according to the rear side and an inner rear inclined surface 60 that moves away from the threshing device 3 according to the rear side, and is formed with an inner front inclined surface. A case 51 of a supply cerealing device 49 is connected to the surface 59.
Therefore, the inner bulging portion 58 can be positioned in the space behind the threshing device 49 in the space provided between the threshing device 3 and the grain tank 5, and the space can be effectively used to make the Glen tank. The volume of 5 can be increased.
