二つのチャフシーブは、揺動しながら各シーブ間から被処理物を漏下させ、唐箕からの送風により風力選別する。被処理物の搬送方向前方側では、被処理物中における単粒の含有率が高く、藁屑の漏下を抑えながら単粒だけを漏下させ、藁屑をより後方へ移送する。 The two chaff sheaves oscillate, let the material to be treated leak from between the sheaves, and sort the wind force by blowing air from the tang. On the front side in the conveyance direction of the workpiece, the single grain content in the workpiece is high, and only the single grain is allowed to leak while suppressing the leakage of the sawdust, and the sawdust is transferred further rearward.

また、揺動棚５１は揺動棚駆動機構の作動により上下前後方向に揺動するので、被処理物は矢印Ｄ方向（図３）に移動しながら、揺動棚５１上に漏下した比重の重い穀粒は選別網６３を漏下し、一番棚板６４で集積され、一番螺旋６５から一番揚穀筒７８を経てグレンタンク３０へ搬送される。グレンタンク３０に貯留された穀粒は、オーガ１８、１９を経由してコンバイン１の外部へ搬送される。 Further, since the swing shelf 51 swings in the vertical and forward / backward directions by the operation of the swing shelf drive mechanism, the specific gravity leaked onto the swing shelf 51 while moving in the direction of arrow D (FIG. 3). The heavy grain leaks through the sorting net 63, is accumulated on the first shelf 64, and is transported from the first spiral 65 to the grain tank 30 via the first lifting cylinder 78. The grains stored in the Glen tank 30 are conveyed to the outside of the combine 1 via the augers 18 and 19.

揺動棚５１の上の被処理物のうち軽量のものは、揺動棚５１の揺動作用と唐箕のファンによる送風に吹き飛ばされて二つのチャフシーブに向けて矢印Ｄ方向に移動し、大きさの小さい二番穀粒は矢印Ｇ方向に漏下して二番棚板８５に集められ、二番螺旋８６で二番揚穀筒８７へ搬送される。 Among the objects to be processed on the swing shelf 51, the lighter one is blown off by the swing action of the swing shelf 51 and the air blown by the fan of Kara, and moves in the direction of arrow D toward the two chaff sheaves. The second small grain leaks in the direction of the arrow G and is collected on the second shelf 85, and is conveyed to the second lifting cylinder 87 by the second spiral 86.

二番穀粒（二番物ということがある）は、正常な穀粒、枝梗粒、藁くずおよび藁くずの中に正常な穀粒が刺さっているササリ粒などの混合物であり、二番揚穀筒８７の中を二番揚穀筒８７の螺旋８７ａにより揚送されて、排出口８７ｂから二番処理室６７の上方へ放出される。二番処理室６７の下部に軸架する二番処理胴７０はエンジンからの動力を伝動して駆動機構により、図４の矢印Ｊ方向に回転する。二番穀粒は二番処理胴７０に植設してある多数の処理歯７０ａに衝突しながら矢印Ｉ方向（図３、図４）に進行する間に二番穀粒の分離と枝梗粒の枝梗の除去を行い、被処理物の一部は二番処理胴７０の下方に設けられた受網７５（図３、図６）を通り抜けて選別部５０に漏下し、被処理物の大部分は移送棚から二つのチャフシーブ方向に送られ、穀粒はチャフシーブと選別網６３（図６）を通り、一番螺旋６５に集められる。
このように二番物を移送棚上に回収して二つのチャフシーブによる再処理をすることにより、穀粒と藁くずとの分離が良好になる。 The second kernel (sometimes called the second product) is a mixture of normal kernels, branch boughs, sawdust and scorpion grains with normal kernels in the waste. The inside of the whipping cylinder 87 is lifted by the spiral 87a of the second whipping cylinder 87 and discharged upward from the second processing chamber 67 through the discharge port 87b. The second processing cylinder 70 pivoted at the lower portion of the second processing chamber 67 transmits power from the engine and rotates in the direction of arrow J in FIG. 4 by the drive mechanism. The second kernel is separated from the second kernel while branching in the direction of arrow I (FIGS. 3 and 4) while colliding with a number of processing teeth 70a planted in the second processing cylinder 70. The part of the object to be processed passes through the receiving net 75 (FIG. 3 and FIG. 6) provided below the second processing cylinder 70 and leaks to the sorting unit 50 to be processed. Is sent from the transfer shelf in the direction of two chaff sheaves, and the grain passes through the chaff sheave and the sorting net 63 (FIG. 6) and is collected in the first spiral 65.
In this way, the second product is collected on the transfer shelf and reprocessed with two chaff sheaves, so that the separation between the grain and the sawdust is improved.

扱室６６を図４の矢印Ａ方向に進行し、扱室６６の終端に到達した被処理物の中の脱穀された穀稈で長尺のままのものは、図４に示す矢印Ａ１方向に搬送され、排藁処理室９５に投入される。 The threshing cereals that have been threshed in the object to be processed that have traveled in the direction of arrow A in FIG. 4 and have reached the end of the handling room 66 are in the direction of arrow A1 shown in FIG.

また、扱室６６の扱胴６９による被処理物搬送方向終端部側に到達した被処理物の中で、藁くずなど短尺のものは、図４に示す扱室６６の扱胴６９による被処理物の搬送方向終端部と排塵処理室６８の排塵処理胴７１による被処理物の搬送方向始端部とを連通する連通口１０１にある排塵処理室入口から矢印Ａ２方向に投入されて、扱室６６からの取り込みを良好にする螺旋７１ｂの作用により排塵処理室６８に入り、排塵処理室６８では回転する排塵処理胴７１の処理歯７１ａにより矢印Ｋ方向（図３、図４）に搬送されながら処理される。なお、排塵処理胴７１の上手側に螺旋７１ｂが設けられ、排塵処理胴７１の下手側に処理歯７１ａが設けられている。排塵処理胴７１の扱室６６側には格子状の排塵処理胴枠（図示せず）が排塵処理胴７１の下側及び扱室６６側の外周に沿って設けられ、排塵処理室６８の濾過体を構成している。 Further, among the objects to be processed which have reached the end of the object to be processed in the conveying direction of the object to be processed by the handling cylinder 69 of the handling chamber 66, short objects such as sawdust are to be processed by the handling cylinder 69 of the handling chamber 66 shown in FIG. The material is introduced in the direction of the arrow A2 from the entrance of the dust treatment chamber at the communication port 101 that communicates the end portion in the conveyance direction of the product and the start direction of the treatment direction of the workpiece by the dust treatment cylinder 71 of the dust treatment chamber 68. The dust 71 enters the dust processing chamber 68 by the action of the spiral 71b that improves the intake from the handling chamber 66. In the dust processing chamber 68, the processing teeth 71a of the dust processing cylinder 71 that rotates rotates in the direction of the arrow K (FIGS. 3 and 4). ) And being processed. A spiral 71 b is provided on the upper side of the dust removal processing cylinder 71, and a processing tooth 71 a is provided on the lower side of the dust removal processing cylinder 71. On the side of the handling chamber 66 of the dust disposal cylinder 71, a lattice-like dust disposal cylinder frame (not shown) is provided along the lower side of the dust disposal cylinder 71 and the outer periphery on the handling chamber 66 side. The filter body of the chamber 68 is configured.

排塵処理室６８に入った少量の穀粒を含む藁くずを主体とする被処理物の中の漏下物（穀粒）は受け網（図示せず）から揺動棚５１上に漏下し、揺動棚５１に設けられたストローラック（図示せず）に誘導されて二番棚板８５から二番揚穀筒８７を経由して二番処理室６７に送られる。なお、同軸上にある二番処理胴７０と排塵処理胴７１の駆動はエンジンから駆動力をプーリ３２（図３、図４）を介して行われる。 Leakage (grains) in the processing object mainly composed of sawdust containing a small amount of grain entering the dust disposal chamber 68 leaks from the receiving net (not shown) onto the swing shelf 51. Then, it is guided to a stroller rack (not shown) provided on the swing shelf 51 and sent from the second shelf 85 to the second processing chamber 67 via the second lifting cylinder 87. The second processing cylinder 70 and the dust exhausting process cylinder 71 on the same axis are driven from the engine via the pulley 32 (FIGS. 3 and 4).

図４に示すように、脱穀装置１５の後部に横断流ファン９１を設け、排塵処理室６８を含む脱穀装置１５内で発生する排塵のうち、比重の軽い藁くず、枝梗および塵埃を含む空気を横断流ファン９１の回転による送風で吸引し、横断流ファン出口から矢印Ｌ方向（図３）へ吹き出して、コンバイン１の外部へ放出する。 As shown in FIG. 4, a crossflow fan 91 is provided at the rear part of the threshing device 15, and among dusts generated in the threshing device 15 including the dusting processing chamber 68, swarf, branch bellflower and dust having a low specific gravity are removed. The contained air is sucked by the air blown by the rotation of the cross flow fan 91, blown out in the direction of arrow L (FIG. 3) from the cross flow fan outlet, and discharged to the outside of the combine 1.

排塵処理室６８から揺動棚５１の終端部に矢印Ｍ（図３）のように落ちた排塵のうち二番穀粒、三番穀粒など小径で比重の重いものは、揺動棚５１の終端部の図示しないストローラックあるいはシーブを矢印Ｇ方向（図３）へ通過して二番棚板８５に漏下し、再び二番処理室６７において処理される。 Of the dust that has fallen from the dust removal processing chamber 68 to the end of the swing shelf 51 as indicated by an arrow M (FIG. 3), those having a small diameter and a high specific gravity, such as second and third grains, A Strollac or sheave (not shown) at the end of 51 passes in the direction of arrow G (FIG. 3), leaks to the second shelf 85, and is again processed in the second processing chamber 67.

また、図４に示すように、連通口１０１の前後には前方中板９６Ｆ及び後方中板９６Ｒを配置しており、連通口１０１後方側の後方中板９６Ｒと後板９８の間の扱胴６９をササリ粒などの四番物の回収胴６９ｂ（図４）とし、扱室６６の被処理物搬送方向終端部側に到達したササリ粒などを回収する回収室６６ａ（図３、図４）を扱室６６内に設けている。回収室６６ａでは、扱胴６９の前部から後部にわたって設けた扱歯６９ａによって脱穀処理された後の排藁穂先部分に対して、回収室６６ａ内に臨む扱胴６９の後端部（回収胴６９ｂ）の扱歯６９ａが作用し、この排藁穂先部分に刺さり込んだ穀粒を揺動棚５１上へ叩き落して回収することができる。 As shown in FIG. 4, a front middle plate 96F and a rear middle plate 96R are arranged before and after the communication port 101, and a handling cylinder between the rear middle plate 96R on the rear side of the communication port 101 and the rear plate 98. 69 is a recovery cylinder 69b (FIG. 4) of a fourth material such as scorpion grains, and a recovery chamber 66a (FIGS. 3 and 4) that recovers scorpion grains and the like that has reached the end of the handling chamber 66 in the conveyance direction of the workpiece. Is provided in the handling chamber 66. In the collection chamber 66a, the rear end portion of the handling cylinder 69 (recovery cylinder) facing the collection chamber 66a with respect to the slaughter tip after the threshing process is performed by the tooth handling 69a provided from the front to the rear of the handling cylinder 69. 69b), the treated teeth 69a act, and the grains stuck into the spear tips can be struck down on the swing shelf 51 and collected.

図６に示すように、被処理物が扱室６６の外部に洩れないようにするために、扱胴６９の側方で、扱室６６内へフィードチェン１４から搬入される被処理物の供給口近傍に、開閉自在の扱胴カバー１０２内側に取り付けられた抵抗板８１が扱胴６９の軸方向と平行に設けられている。また、前記抵抗板８１と扱胴６９の間に、被処理物を扱室６６内方へ案内するための株元側ガイド体８２を抵抗板８１と平行に配置している。 As shown in FIG. 6, in order to prevent the workpiece from leaking outside the handling chamber 66, supply of the workpiece to be carried from the feed chain 14 into the handling chamber 66 on the side of the handling cylinder 69. In the vicinity of the mouth, a resistance plate 81 attached to the inside of the openable and closable barrel cover 102 is provided in parallel with the axial direction of the barrel 69. Further, between the resistance plate 81 and the handling cylinder 69, a stock-side guide body 82 for guiding an object to be processed into the inside of the handling chamber 66 is arranged in parallel with the resistance plate 81.

更に、図６に示すように扱胴カバー１０２の内側には、扱胴６９における搬送方向下手側への被処理物の搬送を制限する上部仕切板８３を設けている。前記上部仕切板８３は、扱胴６９における被処理物の搬送方向から見て下端部が扱胴６９の外周に沿って円弧状であり、扱胴６９の軸芯と直交する方向に板状平面部を有し、そして、上部仕切板８３が扱胴６９における被処理物の搬送方向から見て扱胴６９回転時の扱歯６９ａの回転軌跡と重なるように設けることで、上部仕切板８３と扱歯６９ａとの相互作用により被処理物を搬送上手側に戻すことができる。 Further, as shown in FIG. 6, an upper partition plate 83 is provided on the inner side of the handling cylinder cover 102 to restrict the conveyance of the workpiece to the lower side in the conveying direction of the handling cylinder 69. The upper partition plate 83 has an arcuate lower end portion along the outer periphery of the handling cylinder 69 when viewed from the conveying direction of the workpiece in the handling cylinder 69, and a plate-like plane in a direction perpendicular to the axis of the handling cylinder 69. And the upper partition plate 83 is provided so as to overlap with the rotation locus of the teeth 69a when the handle 69 rotates when viewed from the conveying direction of the workpiece in the handle 69. The object to be processed can be returned to the upper conveyance side by the interaction with the tooth handling 69a.

また、上部仕切板８３を回収室６６ａ手前の後方中板９６Ｒと前後方向でほぼ同じ位置に設けると、該上部仕切板８３及び後方中板９６Ｒとによって穀粒の後方への流れに抵抗が与えられ、上部仕切板８３後方での回収室６６ａにおいてササリ粒の回収が良好となると共に、扱室６６における被処理物の濾過も促進され、三番穀粒の回収ロスも低減する。 Further, when the upper partition plate 83 is provided at substantially the same position in the front-rear direction as the rear middle plate 96R in front of the recovery chamber 66a, the upper partition plate 83 and the rear middle plate 96R provide resistance to the backward flow of the grains. In addition, the recovery of the scorpion grains in the recovery chamber 66a behind the upper partition plate 83 is improved, the filtration of the workpiece in the handling chamber 66 is also promoted, and the recovery loss of the third grain is also reduced.

そして、本実施形態によれば、連通口１０１近傍に、扱胴６９の軸芯と略直交する方向に平面部を有し、扱室６６内の扱胴６９から排塵処理室６８への被処理物の搬送を制限しながら案内する抵抗ガイド板（案内板）８４を設けたことを特徴としている。 According to the present embodiment, the planar portion is provided in the direction substantially perpendicular to the axis of the handling cylinder 69 in the vicinity of the communication port 101, and the cover from the handling cylinder 69 in the handling chamber 66 to the dust removal processing chamber 68 is provided. It is characterized in that a resistance guide plate (guide plate) 84 for guiding while restricting the conveyance of the processed material is provided.

なお、抵抗ガイド板（案内板）８４は、扱胴６９の上方であって、扱網７４の後端部近傍に設けると良い。また、連通口１０１の被処理物の搬送方向手前側に設けても良いし、複数個設けても良い。また、図５及び図６に示すように、扱胴６９上方の扱胴カバー１０２に設けると簡易な構成となる。 The resistance guide plate (guide plate) 84 may be provided above the handling cylinder 69 and in the vicinity of the rear end portion of the handling net 74. Further, the communication port 101 may be provided on the near side in the conveyance direction of the object to be processed, or a plurality thereof may be provided. Further, as shown in FIGS. 5 and 6, a simple structure can be obtained by providing it on the handling cylinder cover 102 above the handling cylinder 69.

抵抗ガイド板（案内板）８４を設けることで、負荷が大きい条件下においても、ある程度被処理物の後方への流れが制限され、被処理物を濾過する扱網７４から後方側に安易に被処理物が送塵されるのを防止して、扱網７４による被処理物のろ過を促進できる。すなわち扱室６６における被処理物の後方への搬送に抵抗を与える抵抗板としての機能を有する。 By providing the resistance guide plate (guide plate) 84, the flow of the workpiece to the rear is limited to some extent even under a heavy load condition, and it is easily covered from the handling net 74 for filtering the workpiece to the rear side. It is possible to prevent the processed material from being sent and facilitate the filtration of the processed material by the handling net 74. That is, it has a function as a resistance plate that gives resistance to the rearward transfer of the workpiece in the handling chamber 66.

一方、抵抗ガイド板（案内板）８４は、扱胴６９の軸芯と略直交する方向に平面部を有しており、リード角度をほとんど設けていないことから、リード角度を設けている場合よりも扱室６６内が過負荷となることを防止できる。そして、リード角度を設けている場合よりも被処理物の排塵処理室６８への流れが制限されず、一層の四番穀粒のロス低減が図れる。また、負荷が大きい条件下においても、扱室６６内の異音発生を防止できる。このように、排塵処理室６８へ被処理物を搬送するガイド板としての機能を有する。 On the other hand, the resistance guide plate (guide plate) 84 has a flat portion in a direction substantially orthogonal to the axis of the handling cylinder 69 and has almost no lead angle, so that the lead angle is provided. In addition, the inside of the handling chamber 66 can be prevented from being overloaded. And the flow to the dust disposal chamber 68 of a to-be-processed object is not restrict | limited compared with the case where the lead angle is provided, and the loss reduction of a 4th grain can be aimed at. Further, it is possible to prevent the generation of abnormal noise in the handling chamber 66 even under a heavy load condition. Thus, it has a function as a guide plate for transporting the object to be processed to the dust disposal chamber 68.

すなわち、抵抗ガイド板（案内板）８４は、扱室６６における被処理物の後方への搬送に抵抗を与える抵抗板としての機能と、排塵処理室６８へ被処理物を搬送するガイド板としての機能を適度に併せ持つ。 That is, the resistance guide plate (guide plate) 84 functions as a resistance plate that gives resistance to the rearward transfer of the object to be processed in the handling chamber 66 and serves as a guide plate for transferring the object to be processed to the dust disposal chamber 68. With moderately combined functions.

そして、連通口１０１よりも後方の扱室６６内に被処理物中のササリ粒などを回収する回収室６６ａを設けると、上記のように抵抗ガイド板（案内板）８４にリード角度を設けている場合よりも扱室６６内が過負荷とならず、後方への搬送が制限されないことから、適度に回収室６６ａにおいてササリ粒を回収することができ、回収効率が向上する。 When the recovery chamber 66a for recovering the scorpion particles in the object to be processed is provided in the handling chamber 66 behind the communication port 101, the lead angle is provided to the resistance guide plate (guide plate) 84 as described above. Since the inside of the handling chamber 66 is not overloaded and the rearward transfer is not restricted as compared with the case where the dust is present, it is possible to appropriately collect the scorpion grains in the recovery chamber 66a, thereby improving the recovery efficiency.

また、案内板８４は連通口１０１の前方中板９６Ｆよりも前側に設けても良いし、図４に示すように、前方中板９６Ｆを挟んで前後に複数個設けても良い。すなわち、扱室６６内における扱胴６９の被処理物の搬送方向に互いに位置をずらして設けても良い。 Further, the guide plate 84 may be provided on the front side of the front middle plate 96F of the communication port 101, or as shown in FIG. 4, a plurality of guide plates 84 may be provided on the front and rear sides of the front middle plate 96F. That is, the positions of the processing cylinders 69 in the handling chamber 66 may be shifted from each other in the conveyance direction of the object to be processed.

図１に示すように、縦オーガ１８の上端部に取り付けた横オーガ（排穀オーガ）１９を水平より下がった位置で収納するオーガ受部２２を扱胴カバー１０２上に設け、横オーガ（排穀オーガ）１９を該オーガ受部２２に収納した場合にはオーガ受部２２の下端部側が扱室６６の内部に突入する構成とした。オーガ受部２２はチューブ部材（支持部材）２２ａと受けスライド部材（オーガ受け部材）２２ｂを一体化した構成であり、また、図５に示すようにオーガ受部２２のチューブ部材２２ａは扱胴カバー１０２への固定部２３により扱胴カバー１０２の上面と下面（扱室内側）にまたがり上下位置を変更可能に支持されている。 As shown in FIG. 1, an auger receiving portion 22 for storing a horizontal auger (a husk auger) 19 attached to the upper end of the vertical auger 18 at a position lower than the horizontal is provided on the handling cylinder cover 102, When the auger receiving portion 22 is housed in the auger receiving portion 22, the lower end portion side of the auger receiving portion 22 enters the inside of the handling chamber 66. The auger receiving portion 22 has a structure in which a tube member (supporting member) 22a and a receiving slide member (auger receiving member) 22b are integrated. As shown in FIG. 5, the tube member 22a of the auger receiving portion 22 is a handling cylinder cover. The upper and lower surfaces (handling chamber side) of the handling cylinder cover 102 are supported by the fixing portion 23 to 102 so that the vertical position can be changed.

図３と図６には排穀オーガ１９を該オーガ受部２２に収納した状態で、オーガ受部２２のチューブ部材２２ａの下端部は二番揚穀筒８７の排出口８７ｂより下方までは下がらず、チューブ部材２２ａの下端部は扱室６６の最前方部に位置する。 3 and 6, the lower end portion of the tube member 22a of the auger receiving portion 22 is lowered below the discharge port 87b of the second lifting cylinder 87 in a state where the auger receiving portion 22 is housed in the auger receiving portion 22. The lower end portion of the tube member 22 a is positioned at the foremost portion of the handling chamber 66.

こうして、排穀オーガ１９をオーガ受部２２へ収納する時には排穀オーガ１９の先端部側は水平より下向きに傾斜配置されるので、コンバイン１を車庫へ格納する場合に排穀オーガ１９が邪魔にならず容易に格納でき、またコンバイン全体にシートを掛け易くなる。また、オーガ受部２２を上記構成にしたので、排穀オーガ１９がオーガ受部２２に収納された位置で排穀オーガ１９から穀粒を排出する作業をしても、チューブ部材２２ａの下端部が二番揚穀筒８７の排出口８７ｂとは離れた位置にあるので排出口８７ｂから排出される穀粒が二番処理室（６７）内に詰まる等の不具合はない。 Thus, when storing the grain auger 19 in the auger receiving part 22, the tip part side of the grain auger 19 is inclined downward from the horizontal, so that the grain auger 19 becomes an obstacle when the combine 1 is stored in the garage. Therefore, it can be easily stored, and the entire combine can be easily put on a sheet. In addition, since the auger receiving portion 22 is configured as described above, the lower end portion of the tube member 22a is provided even when the cereal auger 19 is discharged from the threshing auger 19 at the position where the auger receiving portion 22 is stored. However, since the grain discharged from the outlet 87b is clogged in the second processing chamber (67) , there is no inconvenience such as clogging of the grain discharged from the outlet 87b.

また図５に示すように、オーガ受部２２のチューブ部材２２ａは扱網７４の前方扱網レール７４ａと機体前後方向でほぼ同じ位置に配置し、チューブ部材２２ａは孔のない前方扱網レール７４ａの死角位置にあるので扱網７４の上方部より濾過する穀粒や藁塵などがオーガ受部２２のチューブ部材２２ａとの間で詰まりを起こす不具合がない。 Further, as shown in FIG. 5, the tube member 22a of the auger receiving portion 22 is disposed at substantially the same position in the longitudinal direction of the machine body as the front handle rail 74a of the handle net 74, and the tube member 22a is a front handle net rail 74a having no holes. Therefore, there is no problem that grains, dust, etc., filtered from the upper part of the handling net 74 are clogged with the tube member 22a of the auger receiving part 22.

また、オーガ受部２２は扱室６６の最前端部の機枠の扱胴６９、二番処理胴７０及び排塵処理胴７１にエンジンからの動力を伝達する入力ギヤケース３３のギヤケース凹部３３ａの上方に位置している。 Further, the auger receiving portion 22 is located above the gear case recess 33a of the input gear case 33 that transmits power from the engine to the machine casing 69, the second processing cylinder 70, and the dust processing cylinder 71 at the foremost end of the processing chamber 66. Is located.

上記排穀オーガ１９を水平より下げた角度でオーガ受部２２に収納可能とする構成において、縦オーガ１８の上方に横オーガ（排穀オーガ）１９の回動支点２１（図１）をコンバイン１の機体の終端部右端に配置し、オーガ受部２２は脱穀装置１５の扱室６６の最前方位置としている。この構成により、排穀オーガ１９の収納位置での支持距離（排穀オーガ回動支点２１とオーガ受部２２との間）を長くでき、排穀オーガ１９の支持が安定する。また、排穀オーガ１９を水平より下げて収納した場合、排穀オーガ１９の前端部の下がり量を大きくできるので、排穀オーガ１９の収納時に機体を覆うシートが着脱容易となり、コンパクトにコンバインを収納する効果が高まる。 In the configuration in which the above-described husk auger 19 can be stored in the auger receiving portion 22 at an angle lower than the horizontal, the rotating fulcrum 21 (FIG. 1) of the horizontal auger (husk auger) 19 is combined above the vertical auger 18. The auger receiving portion 22 is located at the forefront position of the handling chamber 66 of the threshing device 15. With this configuration, the support distance at the storage position of the grain auger 19 (between the grain harvesting auger rotation fulcrum 21 and the auger receiving portion 22) can be increased, and the support of the grain harvesting auger 19 is stabilized. Further, when the cereal auger 19 is lowered and stored, the lowering amount of the front end portion of the threshing auger 19 can be increased, so that the seat covering the machine body can be easily attached and detached when the threshing auger 19 is stored. The storage effect is increased.

また、排穀オーガ１９を水平より下がった状態でオーガ受部２２に収納したときには、側面視で排穀オーガ１９は一番揚穀筒７８とほぼ同じ高さで重なっている（図１参照）。そのため、排穀オーガ１９が一番揚穀筒７８の高さを制限することなく、グレンタンク３０の容量を大きく確保できる。 Further, when the cerealing auger 19 is stored in the auger receiving portion 22 in a state of being lowered from the horizontal, the threshing auger 19 overlaps with the height of the first whipping cylinder 78 in a side view (see FIG. 1). . Therefore, the grain auger 19 can secure a large capacity of the Glen tank 30 without limiting the height of the first cereal cylinder 78.

さらに排穀オーガ１９の収納時には、排穀オーガ（横オーガ）１９の基部側を排穀オーガ回動支点２１と機体の右端部後端部に設け、排穀オーガ１９の先端部を機体の前端左端に配置するので、横オーガ回動支点２１で排穀オーガ１９の長さをコンバインの機体寸法内で可能な限り長く構成でき、長距離排出が容易となる。 Further, when storing the grain auger 19, the base side of the grain auger (lateral auger) 19 is provided at the grain auger turning fulcrum 21 and the rear end of the right end of the aircraft, and the tip of the grain auger 19 is disposed at the front end of the aircraft. Since it arrange | positions at the left end, the length of the grain auger 19 can be comprised as long as possible within the body size of a combine with the horizontal auger rotation fulcrum 21, and long distance discharge | emission becomes easy.

オーガ受部２２はチューブ部材２２ａと受けスライド部材２２ｂを一体化した構成であり、図５に示すようにチューブ部材２２ａは扱胴６９のベルト６９ｃ等からなる動力伝動部とほぼ同じ高さで扱室６６の内部の最前端部に設けているので扱胴６９の伝動に支障なく、オーガ収納位置のストローク拡大が行える。 The auger receiving portion 22 has a configuration in which the tube member 22a and the receiving slide member 22b are integrated. As shown in FIG. 5, the tube member 22a is handled at almost the same height as the power transmission portion including the belt 69c of the handling drum 69. Since it is provided at the foremost end inside the chamber 66, the stroke of the auger storage position can be expanded without hindering the transmission of the handling drum 69.

オーガ受部２２のチューブ部材２２ａは扱胴カバー１０２への固定部２３の貫通部を通り、扱胴カバー１０２の上面と下面（扱室内側）にまたがり固定部２３に支持されており、固定部２３の扱胴カバー１０２より上方側（図６の長さＬ１）を下方側（図６の長さＬ２）より長くするか、ほぼ同じ長さにしている。そのため、排穀オーガ１９を水平より下げた状態でオーガ受部２２に収納する場合の収納位置の上下ストロークが従来より大きくなり、また扱胴カバー１０２の上方側の固定部２３の高さが制限されても、扱胴カバー１０２への固定部２３の下方側（扱室内方）への突出長さが長くできるので、コンバインの作業中に排穀オーガ１９をオーガ受部２２に収納していてもオーガ受部２２のゆるみを少なくでき、強度上安定した状態に保つことができる。 The tube member 22a of the auger receiving part 22 passes through the penetration part of the fixing part 23 to the handling cylinder cover 102, and is supported by the fixing part 23 across the upper surface and the lower surface (inside the handling chamber) of the handling cylinder cover 102. The upper side (length L1 in FIG. 6) of the 23 handling cylinder cover 102 is made longer than the lower side (length L2 in FIG. 6) or substantially the same length. For this reason, the vertical stroke of the storage position when storing the auger auger 19 in the auger receiving portion 22 in a state where it is lowered from the horizontal is larger than before, and the height of the fixing portion 23 on the upper side of the barrel cover 102 is limited. However, since the protruding length of the fixing portion 23 to the handling cylinder cover 102 downward (toward the inside of the handling chamber) can be increased, the grain auger 19 is stored in the auger receiving portion 22 during the combine operation. Further, the looseness of the auger receiving portion 22 can be reduced and the strength can be kept stable.

また、チューブ部材２２ａの扱胴カバー１０２への固定部２３の上方部位には、オーガ受部２２の受けスライド部材２２ｂを固定するためのロックフック２２ｃ及びロックピン２２ｄを設けて、これらの部材２２ｃ，２２ｄでチューブ部材２２ａの固定を行うが、ロックフック２２ｃの長さを固定部２３の扱胴カバー１０２より上方側の長さＬ１とほぼ同じくしている。 In addition, a lock hook 22c and a lock pin 22d for fixing the receiving slide member 22b of the auger receiving portion 22 are provided above the fixing portion 23 of the tube member 22a to the barrel cover 102, and these members 22c are provided. 22d, the tube member 22a is fixed, and the length of the lock hook 22c is substantially the same as the length L1 of the fixing portion 23 above the handle cover 102.

オーガの収納高さを位置決めするロックピン２２ｄの抜差は、ロックフック２２ｃをたわませ行うが、ロックフック２２ｃを扱胴カバー１０２より上方側で可能な限り長く設けることで操作荷重が少なくなり操作性がよい。 The lock pin 22d for positioning the auger storage height is deflected by bending the lock hook 22c. However, the operation load is reduced by providing the lock hook 22c as long as possible above the barrel cover 102. Good operability.

なお、図７にはオーガ受部２２を扱胴カバー１０２に取り付けた状態を示す。図７（ａ）は側面図、図７（ｂ）は正面図である。図７はオーガ受部２２は最下部にある状態を示しているが、チューブ部材２２ａにはロックピン２２ｄの挿入孔（図示せず）が高さ方向に３つ設けている。また、ロックフック２２ｃは固定部２３に左右振れ止め用ガイドピン２２ｅと固定ナット２２ｆで支持固定されている。 FIG. 7 shows a state in which the auger receiving portion 22 is attached to the barrel cover 102. FIG. 7A is a side view, and FIG. 7B is a front view. FIG. 7 shows a state in which the auger receiving portion 22 is at the lowermost portion, but the tube member 22a has three insertion holes (not shown) for the lock pins 22d in the height direction. Further, the lock hook 22c is supported and fixed to the fixing portion 23 by a left / right guide pin 22e and a fixing nut 22f.

そしてオーガ受部２２の高さを変える場合には、まず、ロックフック２２ｃをたわませてロックピン２２ｄを抜き、オーガ受部２２を図示より上方に上げて、ロックピン２２ｄを挿入する。 When changing the height of the auger receiving portion 22, first, the lock hook 22c is bent to remove the lock pin 22d, the auger receiving portion 22 is lifted upward from the figure, and the lock pin 22d is inserted.

オーガ受部２２に排穀オーガ１９を水平より下げて収納した場合、扱胴カバー１０２より上方側のチューブ部材２２ａの長さ（Ｌ３）は扱胴カバー１０２より下方側のチューブ部材２２ａの長さ（Ｌ４）より短くする。こうしてオーガ収納位置での上下ストロークを大きくでき、オーガの収納位置を水平より下げた場合の前下がり傾斜角度を大きくできる。 When the grain auger 19 is stored in the auger receiving portion 22 while being lowered from the horizontal, the length (L3) of the tube member 22a above the barrel cover 102 is equal to the length of the tube member 22a below the barrel cover 102. (L4) shorter. In this way, the vertical stroke at the auger storage position can be increased, and the forward downward inclination angle when the auger storage position is lowered from the horizontal can be increased.
