Further, a screw support portion 28c is formed at the tip of the arm portion 28b, and the second transport screw 21 is rotatably supported by the screw support portion 28c.

第１筒状体２３の側部には、上下に２つの連結支持部２９が固着されており、第２フランジ部２８の側部には、上下に２つのブラケット３０が一体成形されている。これらの連結支持部２９及びブラケット３０のそれぞれには、上下方向に貫通する図示しない貫通孔が設けられており、２つのブラケット３０を２つの連結支持部２９で上下から挟むようにしてそれぞれの貫通孔の位置合わせをして組み付けた後、それらの貫通孔に丸棒３３を挿通させて抜け止めされている。これにより、図４に示すように、第２筒状体２４の搬送上流側端部が、第１筒状体２３の搬送下流側端部に対して、丸棒３３を回動支点として軸心Ｐ１周りに揺動可能に支持される。 Two connection support portions 29 are fixed to the side of the first cylindrical body 23 in the vertical direction, and two brackets 30 are integrally formed on the side of the second flange portion 28 in the vertical direction. Each of the connection support portion 29 and the bracket 30 is provided with a through-hole (not shown) penetrating in the vertical direction, and the two brackets 30 are sandwiched by the two connection support portions 29 from above and below. After being aligned and assembled, the round bars 33 are inserted into the through holes to prevent the rods from coming off. As a result, as shown in FIG. 4, the transport upstream end of the second cylindrical body 24 is centered about the round bar 33 as a rotation fulcrum with respect to the transport downstream end of the first cylindrical body 23. It is supported so as to be swingable around P1.

第１フランジ部２７のアーム部２７ｂと第２フランジ部２８のアーム部２８ｂは、第１フランジ部２７と第２フランジ部２８が接当した状態で重複する位置に配設されており、搬送される穀粒の邪魔にならないように、第１搬送スクリュ２０及び第２搬送スクリュ２１の回転軸心を基準として、搬送される穀粒に対向する位置に配設されている。 The arm portion 27b of the first flange portion 27 and the arm portion 28b of the second flange portion 28 are disposed at overlapping positions when the first flange portion 27 and the second flange portion 28 are in contact with each other, and are transported. In order not to interfere with the grains to be conveyed, the rotation axes of the first conveying screw 20 and the second conveying screw 21 are used as a reference so as to face the conveyed grains.

第１フランジ部２７の連結支持部２９とは反対側の側部には、第２フランジ部２８を第１フランジ部２７に連結する連結部２７ｄが形成されており、この連結部２７ｄに、操作具３１の係合部３１ａを係入する凹部２７ｅが形成されている。 A connecting portion 27d for connecting the second flange portion 28 to the first flange portion 27 is formed on the side of the first flange portion 27 opposite to the connecting support portion 29. A recess 27e for engaging the engaging portion 31a of the tool 31 is formed.

第２フランジ部２８のブラケット３０とは反対側の側部には、第２筒状体２４の長手方向に貫通する貫通穴２８ｅが形成された操作具支持部２８ｄが一体成形されている。 On the side of the second flange portion 28 opposite to the bracket 30, an operation tool support portion 28d having a through hole 28e penetrating in the longitudinal direction of the second cylindrical body 24 is integrally formed.

操作部３１は、クランク形状の係合部３１ａと、作業者が把持する把持部３１ｂと、受け部３１ｃとを備えて構成されている。操作部３１は、その係合部３１ａを操作具支持部２８ｄの貫通穴２８ｅに挿通させることによって、係合部３１ａの軸心Ｐ２周りに回動及びスライド可能に支持されている。これにより、操作部３１を、上方側に配置した作用姿勢（図３及び図６の姿勢）と、下方側に配置した非作用姿勢（図４及び図５の姿勢）とに姿勢変更可能に構成されている。
尚、係合部３１ａの貫通穴２８ｅから突出した部分の外周には、コイル状の弾性バネ３２が装着されており、係合部３１ａの先端に設けた受け部３１ｃにより抜け止めされている。 The operation unit 31 includes a crank-shaped engaging portion 31a, a gripping portion 31b that an operator grips, and a receiving portion 31c. The operating portion 31 is supported so as to be rotatable and slidable around the axis P2 of the engaging portion 31a by inserting the engaging portion 31a through the through hole 28e of the operating tool support portion 28d. As a result, the operation unit 31 is configured to be able to change the posture between an action posture (upper position in FIGS. 3 and 6) arranged on the upper side and a non-action posture (posture in FIGS. 4 and 5) arranged on the lower side. Has been.
A coiled elastic spring 32 is mounted on the outer periphery of the portion protruding from the through hole 28e of the engaging portion 31a, and is prevented from coming off by a receiving portion 31c provided at the tip of the engaging portion 31a.

横オーガ９を展開状態から格納状態に切換える場合には、操作具３１を下方に回動させて非作用姿勢に姿勢変更する。これにより、操作具３１の係合部３１ａと第１フランジ部２７の連結部２７ｄとの当接によるロック状態が解除されるため、先端側部分９Ｂが丸棒３３の軸心Ｐ１周りに揺動可能となり（図４参照）、第１フランジ部２７と第２フランジ部２８との連結が外れて、横オーガ９を格納状態とすることができる。 When the horizontal auger 9 is switched from the expanded state to the retracted state, the operation tool 31 is rotated downward to change the posture to the non-acting posture. As a result, the locked state due to the contact between the engaging portion 31a of the operating tool 31 and the connecting portion 27d of the first flange portion 27 is released, so that the distal end side portion 9B swings around the axis P1 of the round bar 33. This becomes possible (see FIG. 4), and the connection between the first flange portion 27 and the second flange portion 28 is released, and the horizontal auger 9 can be brought into the retracted state.

また、横オーガ９を格納状態から展開状態に切換える場合には、先端側部分９Ｂを丸棒３３の軸心Ｐ１周りに揺動させて、第２フランジ部２８を第１フランジ部２７に接当させる。このとき、非作用姿勢にある操作具３１の係合部３１ａが、凹部２７ｅ内に挿入される。そして、操作具３１を、弾性バネ３２の弾性復元力に抗して機体側部分９Ａ側に少し引いてから、上方に回動させて作用姿勢に姿勢変更する。このとき、弾性バネ３２は、軸心Ｐ２方向に圧縮された状態で弾性変形する。そのため、操作具３１の係合部３１ａは、弾性バネ３２の弾性復元力によって第１フランジ部２７の連結部２７ｄに押し付けられる状態となる。これにより、操作具３１の係合部３１ａと第１フランジ部２７の連結部２７ｄとが当接してロック状態となり、第１フランジ部２７と第２フランジ部２８とが連結されて、横オーガ９を展開状態とすることができる。 Further, when the horizontal auger 9 is switched from the retracted state to the expanded state, the distal end portion 9B is swung around the axis P1 of the round bar 33 so that the second flange portion 28 contacts the first flange portion 27. Let At this time, the engaging portion 31a of the operation tool 31 in the non-acting posture is inserted into the recess 27e. Then, the operating tool 31 is pulled slightly toward the airframe side portion 9A against the elastic restoring force of the elastic spring 32, and then rotated upward to change the posture to the working posture. At this time, the elastic spring 32 is elastically deformed while being compressed in the direction of the axis P2. Therefore, the engaging portion 31 a of the operation tool 31 is pressed against the connecting portion 27 d of the first flange portion 27 by the elastic restoring force of the elastic spring 32. As a result, the engaging portion 31a of the operating tool 31 and the connecting portion 27d of the first flange portion 27 come into contact with each other to be locked, and the first flange portion 27 and the second flange portion 28 are connected to each other, thereby Can be in an expanded state.

横オーガ９の先端側部分９Ｂを折り畳んだ格納状態では、第１搬送スクリュ２０は、その搬送下流側端部に設けた第１連動部材３４を介して、第１フランジ部２７のスクリュ支持部２７ｃに回動自在に支持されており、第２搬送スクリュ２１は、その搬送上流側端部に設けた第２連動部材３５を介して、第２フランジ部２８のスクリュ支持部２８ｃに回動自在に支持されている。 In the retracted state in which the distal end side portion 9B of the horizontal auger 9 is folded, the first transport screw 20 is screwed to the screw support portion 27c of the first flange portion 27 via the first interlocking member 34 provided at the transport downstream end portion. The second transport screw 21 is rotatably supported by the screw support portion 28c of the second flange portion 28 via a second interlocking member 35 provided at the upstream end portion of the transport. It is supported.

第１連動部材３４は、第１搬送スクリュ２０の先端に内嵌固定される筒状部材２５と、筒状部材２５の内部奥に設けられる弾性バネ３６と、弾性バネ３６と接する状態で第１搬送スクリュ２０の軸心方向にスライド移動自在で且つ第１搬送スクリュ２０の軸心周りに回転不能に筒状部材２５に内嵌されている連結部材２２とを備えて構成されている。 The first interlocking member 34 is in a state of being in contact with the elastic member 36, a cylindrical member 25 that is fitted and fixed to the tip of the first conveying screw 20, an elastic spring 36 that is provided inside the cylindrical member 25. The connecting member 22 is slidably movable in the axial direction of the conveying screw 20 and is fitted in the cylindrical member 25 so as not to rotate around the axial center of the first conveying screw 20.

連結部材２２の先端部には、凹部２２ａが形成されており、凹部２２ａの縁の相対する位置に２つの切り欠き溝２２ｂが設けられている。第２連動部材３５の先端凸部３５ａには、その両横外側に延出するように連動軸３５ｂが設けられている。 A concave portion 22a is formed at the distal end portion of the connecting member 22, and two notched grooves 22b are provided at positions opposite to the edge of the concave portion 22a. An interlocking shaft 35b is provided on the tip convex portion 35a of the second interlocking member 35 so as to extend outward in both lateral directions.

横オーガ９の先端側部分９Ｂを機体側部分９Ａと略一直線状になるよう展開した展開状態では、第２連動部材３５の先端凸部３５ａが、連結部材２２の凹部２２ａの中に収容されて、第２連動部材３５の連動軸３５ｂが連結部材２２の２つの切り欠き溝２２ｂに入り込むことによって、第１連動部材３４と第２連動部材３５とが係合するように構成される。これにより、第１搬送スクリュ２０と第２搬送スクリュ２１とが連結されて、第１搬送スクリュ２０の回転駆動力が第２搬送スクリュ２１に伝達され得る状態となる。 In the unfolded state where the distal end side portion 9B of the horizontal auger 9 is deployed so as to be substantially in line with the airframe side portion 9A, the distal end convex portion 35a of the second interlocking member 35 is accommodated in the concave portion 22a of the connecting member 22. The first interlocking member 34 and the second interlocking member 35 are engaged with each other when the interlocking shaft 35 b of the second interlocking member 35 enters the two notched grooves 22 b of the connecting member 22. Thereby, the 1st conveyance screw 20 and the 2nd conveyance screw 21 are connected, and it will be in the state where the rotational driving force of the 1st conveyance screw 20 can be transmitted to the 2nd conveyance screw 21.

尚、横オーガ９の先端側部分９Ｂを展開して、操作具３１により第１及び第２フランジ部２７，２８を連結した場合において、第２連動部材３５の連動軸３５ｂの位相と連結部材２２の切り欠き溝２２ｂの位相とが合致しない場合には、弾性バネ３６が圧縮されて第２連動部材３５が搬送下流側に移動する。この状態で、第１搬送スクリュ２０を回転駆動させて連結部材２２が回転すると、第２連動部材３５の連動軸３５ｂに対する連結部材２２の切り欠き溝２２ｂの位相がずれる。そして、弾性バネ３６の付勢力が作用して連結部材２２が搬送下流側に押されて、第２連動部材３５の連動軸３５ｂが連結部材２２の切り欠き溝２２ｂに入り込み、連結部材２２の切り欠き溝２２ｂの位相と第２連動部材３５の連動軸３５ｂの位相とが合致して、第１搬送スクリュ２０と第２搬送スクリュ２１とが連結する。 When the distal end portion 9B of the horizontal auger 9 is expanded and the first and second flange portions 27 and 28 are connected by the operation tool 31, the phase of the interlocking shaft 35b of the second interlocking member 35 and the connecting member 22 are connected. If the phase of the notch groove 22b does not match, the elastic spring 36 is compressed and the second interlocking member 35 moves to the downstream side of conveyance. In this state, when the first conveying screw 20 is driven to rotate and the connecting member 22 rotates, the phase of the notch groove 22b of the connecting member 22 with respect to the interlocking shaft 35b of the second interlocking member 35 is shifted. Then, the urging force of the elastic spring 36 acts to push the connecting member 22 to the downstream side of the conveyance, and the interlocking shaft 35b of the second interlocking member 35 enters the notch groove 22b of the connecting member 22, and the connecting member 22 is cut off. The phase of the notch groove 22b matches the phase of the interlocking shaft 35b of the second interlocking member 35, and the first transport screw 20 and the second transport screw 21 are connected.

かかる構成を採用することで、連結部材２２の切り欠き溝２２ｂの位相と第２連動部材３５の連動軸３５ｂの位相とを合わせながら第１及び第２フランジ部２７，２８を連結しなくても、連結部材２２を回転駆動させることで（穀粒を排出することで）自動的に連結部材２２の切り欠き溝２２ｂの位相と第２連動部材３５の連動軸３５ｂの位相とを合致させることができる。これにより、第１及び第２搬送スクリュ２０，２１を簡易迅速に連結することができ、位相合わせ作業が不要になるため、横オーガ９の展開作業の作業性が良い。 By adopting such a configuration, the first and second flange portions 27 and 28 are not connected while matching the phase of the notch groove 22b of the connecting member 22 and the phase of the interlocking shaft 35b of the second interlocking member 35. By rotating the connecting member 22 (by discharging the grains), the phase of the notch groove 22b of the connecting member 22 and the phase of the interlocking shaft 35b of the second interlocking member 35 can be automatically matched. it can. Thereby, since the 1st and 2nd conveyance screws 20 and 21 can be connected simply and rapidly and a phase alignment operation becomes unnecessary, workability | operativity of the expansion | deployment operation | work of the horizontal auger 9 is good.

図４〜図７に基づいて、穀粒こぼれ防止部材３７の詳細構造について説明する。図６は、横オーガ９が展開状態にあるときの折り畳み機構２６付近の状態を示す側面図であり、図７は、横オーガ９を展開状態から格納状態に切換えるときの穀粒こぼれ防止部材３７の作動状態を示す側面図である。 [Detailed structure of grain spill prevention member]
Based on FIGS. 4-7, the detailed structure of the grain spill prevention member 37 is demonstrated. 6 is a side view showing a state near the folding mechanism 26 when the horizontal auger 9 is in the expanded state, and FIG. 7 is a grain spill prevention member 37 when the horizontal auger 9 is switched from the expanded state to the retracted state. It is a side view which shows the operating state of.

図６に示すように、穀粒こぼれ防止部材３７は、第１筒状体２３の第１フランジ部２７付近及び第２筒状体２４の第２フランジ部２８付近に設けられている。
穀粒こぼれ防止部材３７は、ＳＫ材等で構成される弾性変形自在な第１及び第２弾性部材３８，３９、及び第１及び第２弾性部材３８，３９のそれぞれを第１及び第２筒状体２３，２４に固定するための第１及び第２ステー４０，４１等を備えて構成される。 As shown in FIG. 6, the grain spill prevention member 37 is provided in the vicinity of the first flange portion 27 of the first cylindrical body 23 and in the vicinity of the second flange portion 28 of the second cylindrical body 24.
The grain spill prevention member 37 includes first and second elastically deformable first and second elastic members 38 and 39 made of SK material and the first and second cylinders, respectively. The first and second stays 40, 41 and the like for fixing to the bodies 23, 24 are provided.

第１弾性部材３８は、基部３８ａと、基部３８ａの一端に立設する閉鎖部３８ｂとを備えて構成されている。閉鎖部３８ｂは逆台形状（図５参照）を有しており、その先端に基部３８ａとは反対側に折り曲げられて形成された傾斜部３８ｃを有する。 The first elastic member 38 includes a base portion 38a and a closing portion 38b standing at one end of the base portion 38a. The closing portion 38b has an inverted trapezoidal shape (see FIG. 5), and has an inclined portion 38c formed by being bent to the opposite side to the base portion 38a at the tip thereof.

第２弾性部材３９は、基部３９ａと、基部３９ａの一端に立設する閉鎖部３９ｂとを備えて構成されている。閉鎖部３９ｂは逆台形状（図５参照）を有しており、その先端に基部３９ａとは反対側に折り曲げられて形成された傾斜部３９ｃを有する。 The second elastic member 39 includes a base portion 39a and a closing portion 39b that stands on one end of the base portion 39a. The closing portion 39b has an inverted trapezoidal shape (see FIG. 5), and has an inclined portion 39c formed by bending the tip of the closing portion 39b on the side opposite to the base portion 39a.

第１及び第２ステー４０，４１は、断面形状がコの字状であって、その両端が第１及び第２筒状体２３，２４の外周面の下方側に溶接固定される。 The first and second stays 40 and 41 have a U-shaped cross section, and both ends thereof are welded and fixed to the lower side of the outer peripheral surfaces of the first and second cylindrical bodies 23 and 24.

第１及び第２弾性部材３８，３９のそれぞれは、それらの基部３８ａ，３９ａにおける閉鎖部３８ｂ，３９ｂとは反対側の他端が第１及び第２ステー４０，４１においてボルト４２で締結固定されている。 Each of the first and second elastic members 38 and 39 is fastened and fixed with bolts 42 at the first and second stays 40 and 41 at the other ends of the base portions 38a and 39a opposite to the closing portions 38b and 39b. ing.

図６に示すように、横オーガ９が展開状態にあるときは、第１及び第２弾性部材３８，３９における傾斜部３８ｃ，３９ｃ同士が互いに接触し合うことで、閉鎖部３８ｂ，３９ｂのそれぞれが基部３８ａ，３９ａ側に傾斜するようにわずかに弾性変形し、その状態で傾斜部３８ｃ，３９ｃの先端が第１フランジ部２７の下端に当接する。これにより、第１及び第２弾性部材３８，３９のそれぞれは、第１及び第２フランジ部２７，２８の両開口２７ａ，２８ａから下方側に離れた退避位置に保持される。このとき、基部３８ａ，３９ａのそれぞれは、第１及び第２ステー４０，４１に固定された部分を支点として下方に湾曲するように弾性変形する。 As shown in FIG. 6, when the horizontal auger 9 is in the unfolded state, the inclined portions 38c and 39c of the first and second elastic members 38 and 39 are in contact with each other, so that each of the closed portions 38b and 39b. Is slightly elastically deformed so as to incline toward the base portions 38 a and 39 a, and the tips of the inclined portions 38 c and 39 c abut against the lower end of the first flange portion 27 in this state. Thereby, each of the first and second elastic members 38 and 39 is held at a retracted position away from both the openings 27a and 28a of the first and second flange portions 27 and 28. At this time, each of the base portions 38a and 39a is elastically deformed so as to be bent downward with the portions fixed to the first and second stays 40 and 41 as fulcrums.

そして、図５及び図７に示すように、先端側部分９Ｂを揺動させて横オーガ９を展開状態から格納状態に切換えると、接触していた第１及び第２弾性部材３８，３９の傾斜部３８ｃ，３９ｃが互いに離れるため、閉鎖部３８ｂ，３９ｂのそれぞれがその弾性復元力によって基部３８ａ，３９ａから起き上がる方向に復元移動すると共に、基部３８ａ，３９ａの弾性復元力によって閉鎖部３８ｂ，３９ｂのそれぞれが上方に移動して、第１及び第２フランジ部２７，２８の下方部分を自動的に閉鎖する（即ち、第１及び第２弾性部材３８，３９の閉鎖部３８ｂ，３９ｂのそれぞれは、第１及び第２フランジ部２７，２８の下方部分を閉鎖する閉鎖位置に保持される）。 5 and 7, when the side auger 9 is switched from the expanded state to the retracted state by swinging the distal end side portion 9B, the inclined first and second elastic members 38, 39 that are in contact with each other are tilted. Since the portions 38c and 39c are separated from each other, each of the closing portions 38b and 39b is restored and moved in the direction of rising from the base portions 38a and 39a by the elastic restoring force, and the closing portions 38b and 39b are moved by the elastic restoring force of the base portions 38a and 39a. Each moves upward to automatically close the lower portion of the first and second flange portions 27, 28 (ie, the closing portions 38b, 39b of the first and second elastic members 38, 39 are respectively And held in a closed position for closing the lower portions of the first and second flange portions 27, 28).

尚、本実施形態において横オーガ９を格納状態から展開状態に切換える場合には、手動で第１及び第２弾性部材３８，３９の閉鎖部３８ｂ，３９ｂを下方の退避位置に押下げながら、先端側部分９Ｂを揺動させて第１搬送スクリュ２０と第２搬送スクリュ２１とを連結する。 In the present embodiment, when the lateral auger 9 is switched from the retracted state to the expanded state, the front end of the first and second elastic members 38, 39 is manually pushed down to the retracted position while being pushed down. The first transport screw 20 and the second transport screw 21 are connected by swinging the side portion 9B.

本構成によれば、穀粒の搬出作業を終了した後、横オーガ９をその中間部から折り畳んで短くする格納状態に切換えるときに、第１及び第２フランジ部２７，２８の少なくとも下方部分が穀粒こぼれ防止部材３７で閉鎖される。このため、横オーガ９内の下方に残留する穀粒が、第１及び第２フランジ部２７，２８からこぼれ落ちるのを防止することができる。 According to this configuration, after the grain unloading operation is finished, when switching to the retracted state in which the lateral auger 9 is folded and shortened from its intermediate portion, at least the lower portions of the first and second flange portions 27 and 28 are Closed by a grain spill prevention member 37. For this reason, it is possible to prevent the grains remaining in the lower portion in the horizontal auger 9 from spilling out from the first and second flange portions 27 and 28.

また第１及び第２筒状体２３，２４の内壁面と、第１及び第２搬送スクリュ２０，２１との間には、搬送する穀粒（例えば籾等）の一粒の平均的な大きさよりわずかに大きくて穀粒が無理なく通過できる程度の隙間Ｓ（図３参照）が設けられている。そのため、横オーガ９を格納状態にしてコンバインを走行した場合に、横オーガ９の内側の下方に残留する穀粒が、振動によって隙間Ｓを移動して第１及び第２フランジ部２７，２８からこぼれ落ちる虞がある。 Moreover, between the inner wall surface of the 1st and 2nd cylindrical bodies 23 and 24, and the 1st and 2nd conveyance screws 20 and 21, the average magnitude | size of one grain of grains (for example, rice cake etc.) to convey. A gap S (see FIG. 3) that is slightly larger than that and allows grains to pass through without difficulty is provided. Therefore, when running the combine with the horizontal auger 9 in the retracted state, the grains remaining below the inner side of the horizontal auger 9 move through the gap S due to vibrations, and from the first and second flange portions 27 and 28. There is a risk of spilling.

しかしながら、本構成によれば、格納状態でコンバインを走行した場合でも、第１及び第２フランジ部２７，２８の下方部分が穀粒こぼれ防止部材３７で閉鎖されているので、振動によって第１及び第２フランジ部２７，２８から残留穀粒がこぼれ落ちる虞もない。 However, according to this configuration, even when the combine is driven in the retracted state, the lower portions of the first and second flange portions 27 and 28 are closed by the grain spill prevention member 37. There is no possibility that residual grains spill from the second flange portions 27 and 28.

また特に本構成によれば、穀粒こぼれ防止部材３７が第１及び第２弾性部材３８，３９を備えて構成されており、その弾性復元力によって自動的に第１及び第２フランジ部２７，２８を閉鎖することができるので、横オーガ９を格納状態に切換えるときに、作業者が手動で穀粒こぼれ防止部材３７を閉鎖位置に操作する必要が少なくなる。 In particular, according to the present configuration, the grain spill prevention member 37 is configured to include the first and second elastic members 38 and 39, and the first and second flange portions 27, 28 can be closed, so that it is less necessary for the operator to manually operate the grain spill prevention member 37 to the closed position when switching the horizontal auger 9 to the retracted state.

以下、本発明の第２及び第３実施形態について説明するが、重複説明を避けるため、先の実施形態で説明した構成部品については、同じ符号を付すことにより説明を省略し、先の第１実施形態とは異なる穀粒こぼれ防止部材３７の詳細構造について説明する。 Hereinafter, the second and third embodiments of the present invention will be described. In order to avoid redundant description, the same reference numerals are given to the components described in the previous embodiment, and the description thereof will be omitted. The detailed structure of the grain spillage prevention member 37 different from the embodiment will be described.
