Description

本発明は、穀粒タンクから穀粒を排出する横向き排出筒を2つ折りに折り畳み可能に構成したコンバインの穀粒排出装置に関する。   The present invention relates to a combine grain discharging apparatus configured to be able to fold a horizontal discharge cylinder that discharges a grain from a grain tank into two.

従来のコンバインにおいては、穀粒タンクから穀粒を排出する横向き排出筒を、基端側の第1の横向き排出筒と、この第1の横向き排出筒の先端に連結する先端側の第2の横向き排出筒とで構成し、第2の横向き排出筒を、第1の横向き排出筒の先端から直線状に延長される穀粒排出姿勢と、第1の横向き排出筒と略並行に折り畳んだ格納姿勢とに姿勢変更可能になすと共に、第2の横向き排出筒の基端側に操作レバーを枢支し、この操作レバーの中間部を第2の横向き排出筒に設けた係止部材に係止することにより、前記格納姿勢にある第2の横向き排出筒と当該操作レバーとを一体揺動可能に構成し、以って第1の横向き排出筒に対して第2の横向き排出筒を直線状に延長できるようにしたものが知られている(例えば、特許文献1参照)。   In a conventional combine, a sideways discharge cylinder that discharges the grain from the grain tank is connected to the first sideways discharge cylinder on the base end side and the tip of the first sideways discharge cylinder. Contained with a horizontal discharge cylinder, the second horizontal discharge cylinder is folded in a straight line extending from the tip of the first horizontal discharge cylinder and folded in parallel with the first horizontal discharge cylinder The posture can be changed to the posture, and an operation lever is pivotally supported on the proximal end side of the second lateral discharge cylinder, and an intermediate portion of the operation lever is locked to a locking member provided on the second lateral discharge cylinder By doing so, the second horizontal discharge cylinder in the retracted position and the operation lever are configured to be able to swing together, so that the second horizontal discharge cylinder is linear with respect to the first horizontal discharge cylinder. (See, for example, Patent Document 1) .

また、先端側の第2の横向き排出筒を基端側の第1の横向き排出筒に対して揺動操作するためのハンドルバーを、第2の横向き排出筒の基端側から該第2の横向き排出筒の穀粒搬送方向とは反対方向に向けて延出させて構成したものが知られている(例えば、特許文献2参照)。

JP-A-10-127152 (page 3-4, FIGS. 6-9) JP 2001-251950 A (page 3, FIGS. 1 to 4)

しかし、上述した特許文献1のものは、折り畳まれて格納姿勢にある第2の横向き排出筒を第1の横向き排出筒に対して直線状に延長して穀粒排出姿勢とする際は、先ず第2の横向き排出筒の基端側に枢支されている操作レバーを押圧しながら、第2の横向き排出筒を揺動させなければならないが、螺旋軸が内装されて重量の重い第2の横向き排出筒を簡単に揺動させることはできなかった。そして、前記操作レバーの押圧により第2の横向き排出筒を格納姿勢から約90度揺動させると、両横向き排出筒の連結部を操作レバーが支点越えして該操作レバーを押圧することができなくなるので、更なる第2の横向き排出筒の揺動は、第2の横向き排出筒の基端部に備える係止部材に当該操作レバーの中間部を係止させて行わなければならず面倒であった。   However, in the above-mentioned Patent Document 1, when the second horizontally oriented discharge tube that is folded and in the retracted posture is linearly extended with respect to the first horizontally oriented discharge tube, While pressing the operation lever pivotally supported on the base end side of the second lateral discharge cylinder, the second lateral discharge cylinder must be swung. The sideways discharge cylinder could not be swung easily. When the second sideways discharge cylinder is swung about 90 degrees from the retracted position by pressing the operation lever, the operation lever can push the operation lever over the connecting portion of both sideways discharge cylinders. Therefore, further swinging of the second sideways discharge cylinder must be performed by locking the intermediate portion of the operation lever to a locking member provided at the base end of the second sideways discharge cylinder. there were.

また、特許文献2のものは、先端側の第2の横向き排出筒を揺動操作するために設けたハンドルバーの先端部、即ち該ハンドルバーの握り操作部分は操縦部から大きく離間する方向に向いており、コンバインの操縦部の床面を形成するステップに搭乗したオペレータがハンドルバーを操作する際は、操縦部から前処理装置側に身を乗り出しての不安定な作業姿勢を強いられると共に、螺旋軸が内装されて重量の重い第2の横向き排出筒を揺動させることは容易な作業ではなかった。   Further, in Patent Document 2, the distal end portion of the handle bar provided for swinging the second lateral discharge cylinder on the distal end side, that is, the grip operation portion of the handle bar is in a direction that is largely separated from the control portion. When the operator who has boarded the step that forms the floor surface of the combine control section is operating the handlebar, the operator is forced into an unstable working posture by leaning on the pretreatment device side from the control section. It was not an easy task to swing the second horizontal discharge cylinder, which has a built-in spiral shaft and is heavy.

本発明は、上記課題を解決することを目的としたものであって、穀粒タンクから穀粒を排出する第1の横向き排出筒と、該第1の横向き排出筒の先端側に設けた縦軸に揺動可能に連結する第2の横向き排出筒とを備え、該第2の横向き排出筒を、第1の横向き排出筒の先端から直線状に延長させる穀粒排出姿勢と、第1の横向き排出筒の側方に折り畳んだ格納姿勢とに姿勢変更できるように構成したコンバインの穀粒排出装置において、前記第2の横向き排出筒の基端側に、該第2の横向き排出筒を操縦部側から揺動操作するための操作具を枢支し、該操作具の中途部に当接する梃子支点を介して第2の横向き排出筒を揺動操作可能に構成し、該第2の横向き排出筒を格納姿勢から穀粒排出姿勢に姿勢変更すべく梃子支点に操作具の中途部を当接させた時、平面視における当該操作具の先端が第1の横向き排出筒の脱穀部側外周の延長線から突出して操縦部に臨むようにすると共に、前記縦軸を操作具の中途部に当接する梃子支点として利用したことを特徴としている。 The present invention has been made to solve the above-mentioned problems, and includes a first lateral discharge cylinder that discharges grain from a grain tank, and a vertical provided on the tip side of the first horizontal discharge cylinder. A grain discharge posture comprising a second lateral discharge cylinder coupled to the shaft in a swingable manner, and extending the second lateral discharge cylinder linearly from the tip of the first lateral discharge cylinder; In the combine grain discharging apparatus configured to be changeable to a storage posture folded to the side of the sideways discharge cylinder, the second sideways discharge cylinder is operated on the proximal end side of the second sideways discharge cylinder. An operation tool for swinging from the side is pivotally supported, and the second lateral discharge cylinder is configured to be swingable via a lever fulcrum that contacts the middle part of the operation tool. To change the position of the discharge tube from the retracted position to the grain discharging position, place the middle part of the operation tool on the lever fulcrum. When allowed to contact, as well as to face the steering tip of the operation member protrudes from the extension line of the threshing portion side outer periphery of the first lateral discharge tube in a plan view, the intermediate portion of the operating member the longitudinal axis It is characterized by being used as a lever fulcrum for contact .

請求項1の発明によれば、第1の横向き排出筒の先端側に設けた縦軸に揺動可能に連結する第2の横向き排出筒の基端側に、該第2の横向き排出筒を操縦部側から揺動操作するための操作具を枢支し、該操作具の中途部に当接する梃子支点を介して第2の横向き排出筒を揺動操作可能に構成すると共に、該第2の横向き排出筒を格納姿勢から穀粒排出姿勢に姿勢変更すべく梃子支点に操作具の中途部を当接させた時、平面視における当該操作具の先端が第1の横向き排出筒の脱穀部側外周の延長線から突出して操縦部に臨むので、コンバインの操縦部に搭乗したオペレータが前記操作具を操作する際に、その中途部に当接する梃子支点を介しての梃子作用によって、重量の重い第2の横向き排出筒を少ない操作力でスムーズに揺動させることができるので作業性に優れ、また操縦部から身を乗り出しての不安定な作業姿勢を強いられることもない。
更に、前記縦軸を操作具の中途部に当接する梃子支点として利用することによって、当該梃子支点を特別な部品を設けることなく安価に構成することができる。
According to the first aspect of the present invention, the second lateral discharge cylinder is disposed on the base end side of the second lateral discharge cylinder that is swingably connected to the vertical axis provided on the distal end side of the first lateral discharge cylinder. An operating tool for swinging operation from the control unit side is pivotally supported, and the second lateral discharge cylinder is configured to be swingable via a lever fulcrum that contacts the middle part of the operating tool. When the middle part of the operation tool is brought into contact with the lever fulcrum to change the posture of the horizontal discharge tube from the retracted posture to the grain discharge posture, the tip of the operation tool in plan view is the threshing portion of the first horizontal discharge tube Since it protrudes from the extension line on the outer side of the side and faces the control section, when the operator who is on the control section of the combiner operates the operation tool, the lever action through the lever fulcrum that abuts on the middle part thereof, Smoothly swing the heavy second sideways discharge cylinder with less operating force Excellent workability because it also be that there is no strong an unstable work attitude of leaned over from the steering unit.

The driven spiral shaft 14 provided in the side discharge cylinder 11b is movable in the axial direction and coupled to the drive side spiral shaft 13 provided in the drive side discharge cylinder 11a. A grain conveying spiral shaft (not shown) is provided which is fitted to the spiral shaft 14a and transmits the rotation of the connecting spiral shaft 14a.

そして、駆動側排出筒11aの先端部(折畳基点部)には、駆動側螺旋軸13を回転自在に保持する軸受部15を設けている。この軸受部15は、駆動側螺旋軸13の軸受15aと、従動側螺旋軸14の連結螺旋軸14aを嵌合させるガイド部15bを備えている。   And the bearing part 15 which hold | maintains the drive side helical shaft 13 rotatably is provided in the front-end | tip part (folding base point part) of the drive side discharge cylinder 11a. The bearing portion 15 includes a guide portion 15 b that fits the bearing 15 a of the drive side spiral shaft 13 and the connecting spiral shaft 14 a of the driven side spiral shaft 14.

また、駆動側排出筒11aの先端部と従動側排出筒11bの基端部には、格納姿勢状態にある従動側排出筒11bを、図1に二点鎖線で示すA矢印の如く揺動させて駆動側排出筒11aの先端から直線状に延長させる穀粒排出姿勢とした時、両筒11a,11bの連結部(面)を形成するフランジ16a,16bを夫々設けている。   Further, the driven discharge cylinder 11b in the retracted posture is swung as indicated by the two-dot chain line in FIG. 1 at the distal end of the drive discharge cylinder 11a and the proximal end of the driven discharge cylinder 11b. When the grain discharge posture is extended linearly from the tip of the drive side discharge cylinder 11a, flanges 16a and 16b that form the connecting portions (surfaces) of both the cylinders 11a and 11b are provided.

更に、上述した駆動側排出筒11aのフランジ16aと従動側排出筒11bのフランジ16bの上下には、駆動側排出筒11aに対して従動側排出筒11bを揺動可能に連結する支点軸としての縦軸17を挿通支持すべく、ホルダ18a,18bとホルダ19a,19bとを夫々固設してある。   Further, above and below the flange 16a of the drive-side discharge cylinder 11a and the flange 16b of the driven-side discharge cylinder 11b, a fulcrum shaft that pivotally connects the driven-side discharge cylinder 11b to the drive-side discharge cylinder 11a. Holders 18a and 18b and holders 19a and 19b are fixed to insert and support the vertical axis 17, respectively.

そして、駆動側排出筒11aのフランジ16aに固設した上下のホルダ18a,18bに、従動側排出筒11bのフランジ16bに固設した上下のホルダ19a,19bが内嵌した状態で、これらのホルダ18a,18b,19a,19bに縦軸17を挿通支持できるように構成している。   The upper and lower holders 19a and 19b fixed to the flange 16b of the driven-side discharge cylinder 11b are fitted in the upper and lower holders 18a and 18b fixed to the flange 16a of the drive-side discharge cylinder 11a. The vertical axis 17 can be inserted and supported in 18a, 18b, 19a, 19b.

また、駆動側排出筒11aの先端部には、従動側排出筒11bを揺動させて駆動側排出筒11aの先端から直線状に延長させて穀粒排出姿勢とした時、この従動側排出筒11bの穀粒排出姿勢を保持するためのロック金具21が取り付けてあり、該ロック金具21に備えるクランプアーム22を従動側排出筒11bの基端部に設けた係止部材23に係止させ、次いでロックレバー24を固定方向に回動させることによって穀粒排出オーガ11の穀粒排出姿勢を保持することができる。   Further, when the driven-side discharge cylinder 11b is swung at the front end portion of the drive-side discharge cylinder 11a so as to extend linearly from the front-end of the drive-side discharge cylinder 11a to have a grain discharging posture, this driven-side discharge cylinder A lock fitting 21 for holding the grain discharge posture of 11b is attached, and a clamp arm 22 provided in the lock fitting 21 is locked to a locking member 23 provided at the base end portion of the driven-side discharge cylinder 11b, Next, the grain discharge posture of the grain discharge auger 11 can be maintained by rotating the lock lever 24 in the fixing direction.

そして、従動側排出筒11bの基端側下部の機体2外側寄りに、この従動側排出筒11bを操縦部4側から揺動操作可能な棒状操作具25の基端部を枢支すると共に、従動側排出筒11bを駆動側排出筒11aに対して略並行に折り畳んだ格納姿勢状態において、当該棒状操作具25の把持部B側を駆動側排出筒11aの先端側下部の操縦部4寄りに設けた樹脂製クランプ26に保持できるように構成している。この時、棒状操作具25は、駆動側排出筒11aと従動側排出筒11bの下方で、且つ両排出筒11a,11bと略直交状態で樹脂製クランプ26に保持されるようになっている。尚、樹脂製クランプ26は、駆動側排出筒11aの操縦部4寄りに固設した正面視L字状のホルダ27の下面側に嵌着してある。   Then, on the lower side of the machine body 2 on the lower side of the base end side of the driven side discharge tube 11b, the base end portion of the rod-like operation tool 25 capable of swinging the driven side discharge tube 11b from the control unit 4 side is pivoted, In the retracted posture state in which the driven-side discharge cylinder 11b is folded substantially parallel to the drive-side discharge cylinder 11a, the grip portion B side of the rod-like operation tool 25 is closer to the control section 4 at the lower end on the front end side of the drive-side discharge cylinder 11a. The resin clamp 26 is provided so that it can be held. At this time, the rod-like operation tool 25 is held by the resin clamp 26 below the drive side discharge cylinder 11a and the driven side discharge cylinder 11b and in a substantially orthogonal state with both the discharge cylinders 11a and 11b. The resin clamp 26 is fitted to the lower surface side of an L-shaped holder 27 that is fixed to the drive side discharge cylinder 11a and close to the control unit 4.

更に詳しくは、上述した棒状操作具25は、把持部B側を下方に曲げ形成した丸棒またはパイプ材からなり、その基端部には、図示しない取付孔を備えたプレート25aを固設している。そして、このプレート25aの取付孔を枢支すべく、従動側排出筒11bの機体2外側寄りにはホルダ28が固設してあり、該ホルダ28に前記プレート25aを揺動自在で且つ若干の上下動を融通させながらカラー29及びボルト30を用いて取り付けてある。   More specifically, the rod-like operation tool 25 described above is made of a round bar or pipe material formed by bending the holding part B side downward, and a plate 25a having a mounting hole (not shown) is fixed to the base end portion thereof. ing. In order to pivotally support the mounting hole of the plate 25a, a holder 28 is fixed on the outer side of the machine body 2 of the driven-side discharge cylinder 11b, and the plate 25a can be swung freely in the holder 28 and slightly. It is attached using the collar 29 and the bolt 30 while allowing vertical movement.

また、従動側排出筒11bを駆動側排出筒11aに対して略並行に折り畳んだ格納姿勢状態の時、当該従動側排出筒11bの開き方向への不要な揺動動作を防止するために、棒状操作具25の把持部B側の上面には従動側排出筒11bの開き防止ストッパーとして突片31を固設してあり、この突片31は、棒状操作具25を前記樹脂製クランプ26に保持した状態で、該樹脂製クランプ26が嵌着するホルダ27の外側に当接して開き防止ストッパーとして作用する。   Further, when the driven-side discharge cylinder 11b is folded in substantially parallel to the drive-side discharge cylinder 11a, a rod-like shape is used to prevent unnecessary swinging movement in the opening direction of the driven-side discharge cylinder 11b. A protrusion 31 is fixed on the upper surface of the operation tool 25 on the gripping part B side as a stopper for preventing the opening of the driven discharge cylinder 11b, and the protrusion 31 holds the rod-shaped operation tool 25 on the resin clamp 26. In this state, the resin clamp 26 comes into contact with the outside of the holder 27 to which the resin clamp 26 is fitted, and acts as an opening prevention stopper.

尚、図中符号32は、従動側排出筒11bを駆動側排出筒11aに対して略並行に折り畳んだ時、従動側排出筒11bが上下方向に揺動しないように保持すると共に、駆動側排出筒11aと従動側排出筒11bとの間隔を保持する排出筒保持部材であって、該排出筒保持部材32は、駆動側排出筒11aに取り付けてあり、その従動側排出筒11bとの当接面にはクッション材33を貼付している。   Reference numeral 32 in the figure indicates that when the driven side discharge cylinder 11b is folded substantially parallel to the drive side discharge cylinder 11a, the driven side discharge cylinder 11b is held so as not to swing in the vertical direction, and the drive side discharge A discharge cylinder holding member that holds the space between the cylinder 11a and the driven side discharge cylinder 11b, and the discharge cylinder holding member 32 is attached to the drive side discharge cylinder 11a and is in contact with the driven side discharge cylinder 11b. A cushion material 33 is attached to the surface.

ところで、穀粒タンク7内に一時的に貯留された穀粒を穀粒排出装置9によってトラックやトレーラ等の輸送手段に排出する際は、駆動側排出筒11aに対して略並行に折り畳まれて格納姿勢状態にある従動側排出筒11bを、その揺動支点軸である縦軸17を中心に図1に二点鎖線で示すA矢印の如く揺動させて、当該従動側排出筒11bが駆動側排出筒11aの先端から直線状に延長される穀粒排出姿勢とする。   By the way, when the grain temporarily stored in the grain tank 7 is discharged to a transportation means such as a truck or a trailer by the grain discharging device 9, it is folded substantially in parallel to the driving side discharge cylinder 11a. The driven-side discharge cylinder 11b is driven by swinging the driven-side discharge cylinder 11b in the retracted posture around the vertical axis 17 that is the swing fulcrum axis as shown by an arrow A shown by a two-dot chain line in FIG. It is set as the grain discharge attitude | position extended linearly from the front-end | tip of the side discharge cylinder 11a.

そして、上述の如く従動側排出筒11bを揺動させるには、図3及び図4に示すように、先ず樹脂製クランプ26に保持されている棒状操作具25の保持状態を解除して、該棒状操作具25を図4に示すC矢印方向に揺動させ、次いで、従動側排出筒11bの揺動支点軸である縦軸17の下端部P、即ち該縦軸17を挿通支持する駆動側排出筒11aの下部ホルダ18bから縦軸17の下端が下方に突出する部分に、当該棒状操作具25の中途部を機体2の前方側から当接させる。   In order to swing the driven-side discharge cylinder 11b as described above, first, the holding state of the rod-like operation tool 25 held by the resin clamp 26 is released, as shown in FIGS. The bar-like operating tool 25 is swung in the direction of arrow C shown in FIG. 4, and then the lower end portion P of the vertical axis 17 which is the rocking fulcrum shaft of the driven-side discharge cylinder 11b, that is, the driving side for inserting and supporting the vertical axis 17 The midway part of the rod-like operation tool 25 is brought into contact with the part of the lower end of the vertical axis 17 projecting downward from the lower holder 18b of the discharge cylinder 11a from the front side of the machine body 2.

この時、平面視における棒状操作具25の先端部、即ち把持部B側は、駆動側排出筒11aの脱穀部5側外周の延長線X(図4参照)から突出して操縦部4に臨むので、コンバイン1の操縦部4に搭乗したオペレータが、当該棒状操作具25を操作する際に操縦部4から身を乗り出しての不安定な作業姿勢を強いられることがない。   At this time, the front end portion of the rod-like operation tool 25 in plan view, that is, the gripping portion B side protrudes from the extension line X (see FIG. 4) on the outer periphery of the threshing portion 5 side of the drive side discharge tube 11a and faces the control portion 4. The operator who has boarded the control unit 4 of the combine 1 is not forced to take an unstable work posture by getting out of the control unit 4 when operating the rod-shaped operating tool 25.

そして、棒状操作具25の中途部に当接する縦軸17の下端部Pは、従動側排出筒11bの基端側に基端部を枢支した棒状操作具25の梃子支点として作用するので、図5にD矢印で示すように、当該棒状操作具25の把持部Bを持って平面視で時計回り方向に回動させると、前記梃子支点(P)を介しての梃子作用によって、重量の重い従動側排出筒11を少ない操作力でスムーズに揺動させることができるので作業性に優れる。   And since the lower end part P of the vertical axis | shaft 17 contact | abutted in the middle part of the rod-shaped operation tool 25 acts as a lever fulcrum of the rod-shaped operation tool 25 which pivotally supported the base end part on the base end side of the driven side discharge cylinder 11b. As shown by the arrow D in FIG. 5, when the handle B of the rod-like operation tool 25 is held and rotated clockwise in plan view, the weight of the weight is increased by the lever action via the lever fulcrum (P). Since the heavy driven discharge cylinder 11 can be smoothly swung with a small operating force, the workability is excellent.

更に、上述したように従動側排出筒11bの揺動支点軸である縦軸17の下端部Pを棒状操作具25の梃子支点として利用することによって、この梃子支点を特別な部品を設けることなく安価に構成することができると共に、前記縦軸17の上端側は上方に突出しておらず、コンバイン1の全体を覆うカバーを装着する際に、該カバーが縦軸17の上端に引っ掛かって邪魔になることはない。また、棒状操作具25が当接する縦軸17の下端部P、即ち棒状操作具25の梃子支点となる部分を凹状に形成することにより、当該棒状操作具25と梃子支点の係合性を向上させることもできる。   Furthermore, by utilizing the lower end portion P of the vertical axis 17 that is the swing fulcrum shaft of the driven-side discharge cylinder 11b as described above as the lever fulcrum of the rod-like operating tool 25, this lever fulcrum is not provided with any special parts. The upper end side of the vertical axis 17 does not protrude upward, and the cover is caught on the upper end of the vertical axis 17 when it is attached. Never become. Further, the lower end portion P of the vertical axis 17 with which the rod-shaped operating tool 25 abuts, that is, the portion serving as the lever fulcrum of the rod-shaped operating tool 25 is formed in a concave shape, thereby improving the engagement between the rod-shaped operating tool 25 and the lever fulcrum. It can also be made.

そして、上述の如く棒状操作具25の中途部を梃子支点である縦軸17の下端部Pに当接させた状態で、当該棒状操作具25の把持部B側を平面視で時計回り方向に押しながら、従動側排出筒11bをその揺動支点軸である縦軸17を中心に約180度揺動させると、図6に示すように、従動側排出筒11bが駆動側排出筒11aの先端から直線状に延長された穀粒排出姿勢となる。   Then, as described above, with the middle portion of the rod-like operation tool 25 in contact with the lower end portion P of the vertical axis 17 that is the lever fulcrum, the gripping portion B side of the rod-like operation tool 25 is clockwise in plan view. When the driven-side discharge cylinder 11b is swung about 180 degrees around the vertical axis 17 that is the rocking fulcrum shaft while being pushed, as shown in FIG. 6, the driven-side discharge cylinder 11b becomes the tip of the drive-side discharge cylinder 11a. It becomes the grain discharge posture extended linearly from.

その後、棒状操作具25を駆動側排出筒11aの先端側下部の操縦部4寄りに設けた樹脂製クランプ36に保持すると共に、駆動側排出筒11aの先端部に備えるロック金具21のクランプアーム22を、従動側排出筒11bの基端部に設けた係止部材23に係止させ、次いでロックレバー24を固定方向に回動させることによって、従動側排出筒11bを駆動側排出筒11aに連結固定した穀粒排出オーガ11の穀粒排出姿勢を保持することができる。尚、前記樹脂製クランプ36は、駆動側排出筒11aの操縦部4寄りに固設した正面視L字状のホルダ27の下面側に嵌着してある。   Thereafter, the rod-like operation tool 25 is held by the resin clamp 36 provided near the control unit 4 at the lower end of the driving side discharge cylinder 11a and the clamp arm 22 of the lock fitting 21 provided at the tip of the driving side discharge cylinder 11a. Is engaged with a locking member 23 provided at the base end portion of the driven side discharge cylinder 11b, and then the lock lever 24 is rotated in the fixing direction to connect the driven side discharge cylinder 11b to the drive side discharge cylinder 11a. The fixed grain discharging auger 11 can hold the grain discharging posture. The resin clamp 36 is fitted on the lower surface side of an L-shaped holder 27 that is fixed to the drive side discharge cylinder 11a and close to the control section 4.

しかる後に、直線状に連結固定された穀粒排出オーガ11を上限位置まで起こしてから、この穀粒排出オーガ11を穀粒の輸送手段であるトラックやトレーラ等の待機位置まで旋回させ、次いで適切な高さ位置まで下降させて停止することにより、穀粒タンク7内に一時的に貯留された穀粒を排出できるようになっている。   Thereafter, the grain discharge auger 11 connected and fixed in a straight line is raised to the upper limit position, and then the grain discharge auger 11 is swung to a standby position such as a truck or trailer which is a grain transporting means. The grain temporarily stored in the grain tank 7 can be discharged by being lowered to a high position and stopped.
