In addition, it is possible to perform wind selection with the direct selection net 63 by blowing air from the Kara 79, lightening the load on the sheave 53, and enabling efficient threshing. From the Karatsumi 79, the air dividing part 105 is provided in the air flow path, the air is divided by the air dividing part 105, and the air volume is adjusted at the upper and lower parts.

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、移送棚52上に漏下した比重の重い穀粒は選別網63を矢印E方向に通過し、一番棚板64で集積され、一番螺旋65aから一番揚穀筒65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 driving mechanism, the object to be processed is moved in the direction of arrow D (FIG. 3) and the specific gravity leaked onto the transfer shelf 52 is increased. The heavy kernel passes through the sorting net 63 in the direction of arrow E, is accumulated on the first shelf 64, and is conveyed from the first spiral 65a to the grain tank 30 via the first lifting cylinder 65. 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79のファン79aによる送風に吹き飛ばされて、移送棚52からシーブ53に向けて矢印D方向に移動し、ストローラック62の上で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上を通り、二番螺旋86の設置部分に集められ、二番還元筒87へ搬送される。さらに軽いものは横断流ファン91で矢印F方向の機外に排出される。   Among the objects to be processed on the swing shelf 51, the lighter ones are blown off by the swing action of the swing shelf 51 and the air blown by the fan 79 a of the Karatsu 79, and in the direction of arrow D from the transfer shelf 52 toward the sheave 53. The second grain having a small size on the Strollack 62 leaks in the direction of the arrow G, passes through the second shelf 85, and is collected at the installation part of the second spiral 86, and the second reduction. It is conveyed to the tube 87. Lighter ones are discharged out of the machine in the direction of arrow F by a cross flow fan 91.

揺動棚51に取り付けたストローラック62は、揺動棚51の後部側に、その前側の基部が取り付けられ、ストローラック62の後部側を自由端とする構成である。そして、ストローラック62から漏下した被処理物は二番棚板85側に集められ、二番螺旋86で二番還元筒87へ搬送される(図3)。   The Strollac 62 attached to the swing shelf 51 has a configuration in which a base portion on the front side is attached to the rear side of the swing shelf 51 and the rear side of the Strollack 62 is a free end. Then, the objects to be processed that have leaked from the Strollac 62 are collected on the second shelf 85 side and conveyed to the second return cylinder 87 by the second spiral 86 (FIG. 3).

図4の平面図及び図3のA−A線矢視図である図6に示すように平面視及びA−A線断面視において、二番還元筒87と二番処理胴70の軸心のずれ(図4の長さA、図6の長B)が少なく、二番還元筒87の排出口87bのほぼ真下に二番処理胴70が配置されている。   As shown in the plan view of FIG. 4 and the AA line arrow view of FIG. 3, the shafts of the second reduction cylinder 87 and the second processing cylinder 70 in the plan view and the AA line sectional view are shown in FIG. There is little deviation (length A in FIG. 4, length B in FIG. 6), and the second processing cylinder 70 is disposed almost directly below the discharge port 87 b of the second reduction cylinder 87.

上記のように構成することで、二番処理胴70と二番還元筒87を共に扱室66内にコンパクトに配置できる。従来は扱室66の外側に二番還元筒87を突出させて配置していたが、扱室66内に二番還元筒87を配置することができので、扱室66の横幅を比較的小さくできる利点がある。 By configuring as described above, both the second processing cylinder 70 and the second reduction cylinder 87 can be compactly arranged in the handling chamber 66. It has been conventionally arranged to protrude double dip reduction cylinder 87 to the outside of the threshing chamber 66, since Ru can place double dip reduction cylinder 87 to the threshing chamber 66, relatively the width of threshing chamber 66 There is an advantage that can be reduced.

また、二番還元筒排出口87bからの二番物を容易に二番処理胴70に導くことができる。さらに二番処理胴70の処理始端部側の支持を二番還元筒87の支持部87e(図5参照)で行えるので、二番処理胴70を支持(軸支)するための特別な部材を設ける必要がなく、この二番処理胴70を支持する上で強度的にも優れている。 Further, the second product from the second reduction cylinder discharge port 87b can be easily guided to the second processing cylinder 70. Since further allows the support of the processing start end side of the double-dip process cylinder 70 with double-dip supporting portion 87 of the reduction cylinder 87 e (see FIG. 5), a special member for supporting the double-dip process cylinder 70 (journaled) It is excellent in strength in supporting the second processing cylinder 70.

また、二番還元筒87の排出口87bはコンバイン機体の前後方向において、二番処理胴70による二番処理物の搬送方向の上手側(二番処理物の処理始端部側=機体後方側)に配置しているので、扱室66内に設けた二番還元筒87の排出口87bは、コンバイン機体の前後方向において二番処理胴70による二番物の搬送上手側にある処理始端部の上方に位置することになり、二番処理胴70の上手側から下手側へ(矢印I方向)の二番物搬送領域の長さを大きく取ることで、二番還元物を十分処理できるので、二番処理胴70の処理を有効に行うことができる。また二番還元筒87の排出口87bに対応する二番還元筒87の壁面の外側に向けて排出案内板87dを取り付けている。   Further, the discharge port 87b of the second reduction cylinder 87 is located on the upper side in the transport direction of the second processed material by the second processing cylinder 70 in the front-rear direction of the combine machine body (the processing start end side of the second processed product = the rear side of the machine body). Therefore, the discharge port 87b of the second reducing cylinder 87 provided in the handling chamber 66 is located at the processing start end portion on the upper side of the second product transfer by the second processing cylinder 70 in the front-rear direction of the combine machine body. Since the second reduced product can be processed sufficiently by taking a large length of the second product transfer region from the upper side to the lower side (in the direction of arrow I) of the second processing cylinder 70, it will be located above. The second processing cylinder 70 can be processed effectively. A discharge guide plate 87d is attached to the outside of the wall surface of the second reduction cylinder 87 corresponding to the discharge port 87b of the second reduction cylinder 87.

図3に示すように扱胴69に隣接して二番処理胴70を配置し、該二番処理胴70は扱室66を構成する壁面の前壁である前板66aと中板66bとの間に設け、二番処理胴70の後端側を二番還元筒87に設けた支持部87e(図5)で支持している。なお、中板66bは二番処理胴70の後端部を基準に扱室66内にある扱胴69の周囲の空間を仕切る板である。   As shown in FIG. 3, a second processing cylinder 70 is disposed adjacent to the handling cylinder 69, and the second processing cylinder 70 includes a front plate 66 a and a middle plate 66 b that are front walls of a wall surface that constitutes the handling chamber 66. The rear end side of the second processing cylinder 70 is supported by a support portion 87e (FIG. 5) provided on the second reduction cylinder 87. The middle plate 66b is a plate that partitions the space around the handling cylinder 69 in the handling chamber 66 with the rear end portion of the second processing cylinder 70 as a reference.

このように、扱室66内に設けた二番処理胴70の一端を二番還元87で支持することで二番処理胴70の支持が強固となり、剛性が高まる。また、複胴構成とすることで扱室66内の穀稈処理能力が向上し、脱穀能力が高まる。   In this way, by supporting one end of the second processing cylinder 70 provided in the handling chamber 66 by the second reduction 87, the support of the second processing cylinder 70 is strengthened and the rigidity is increased. In addition, by adopting a double cylinder configuration, the grain processing capacity in the handling chamber 66 is improved, and the threshing capacity is increased.

さらに、図7に二番処理胴70付近の要部分解図に示すように、二番処理胴70は扱胴・処理胴入力ギアケース25からの入力軸26と扱室66の中板66bに設けた支持軸27との間をそれぞれ二番処理胴70に設けたスペーサ70dとベアリング70eを介してカップリング部70c1、70c2に挟み込むカップリング構成とすることで二番処理胴70の前方に取り外し可能としている。
また、扱胴69の回転軸69bの前端部は前板66aに支持され、回転軸69bの後端部は扱室66の後壁部を構成する後板66cに支持されている。
Further, as shown in an exploded view of the main part in the vicinity of the second processing cylinder 70 in FIG. 7, the second processing cylinder 70 is connected to the input shaft 26 from the processing cylinder / processing cylinder input gear case 25 and the middle plate 66b of the processing chamber 66. The coupling between the support shaft 27 and the support shaft 27 is sandwiched between the coupling portions 70c1 and 70c2 via the spacer 70d provided on the second processing cylinder 70 and the bearing 70e. It is possible.
Further, the front end portion of the rotation shaft 69 b of the handling cylinder 69 is supported by the front plate 66 a, and the rear end portion of the rotation shaft 69 b is supported by the rear plate 66 c constituting the rear wall portion of the handling chamber 66.

また、図6に示すように、扱胴69の外周部に配置される受網74は上方受網74aと下方受網74bからなり、二番還元筒87の側部に上方受網74aが取り付けられ、揺動棚51の上方に下方受網74bが取り付けられている。そして二番処理胴70には主に上方受網74aから扱胴69で処理された穀粒と細かい藁くずなどが落下して供給される。   Further, as shown in FIG. 6, the receiving net 74 disposed on the outer peripheral portion of the handling cylinder 69 is composed of an upper receiving net 74a and a lower receiving net 74b, and the upper receiving net 74a is attached to the side portion of the second reduction cylinder 87. A lower receiving net 74 b is attached above the swing shelf 51. The second processing cylinder 70 is supplied mainly with grains and fine crumbs that have been processed by the handling cylinder 69 from the upper receiving net 74a.

従って、二番処理胴70では扱胴69で処理された処理物が上方受網74aを通過して供給され、さらに二番還元筒87から二番物が供給されるので、穀粒の単粒化や藁くずの細断、藁くずと穀粒の分離などを行うことができ、揺動棚51での処理物の選別能を補助しつつ扱室66における全体での処理物の処理能力を高めることができる。   Therefore, in the second processing cylinder 70, the processed product processed in the handling cylinder 69 is supplied through the upper receiving net 74a, and further, the second product is supplied from the second reduction cylinder 87. , Shredding of swarf, separation of swarf and grains, and the like, and the processing capacity of the entire processing object in the handling chamber 66 while assisting the sorting ability of the processing object in the swing shelf 51. Can be increased.

また、図6に示すように二番処理胴70の回転軸(第1回転軸)70bを扱胴69の回転軸(軸心)69bよりも下方に設け、二番還元筒87の排出口87bは扱胴69の軸心とほぼ高さを等しくしている。
このように、二番処理胴70は扱胴69の軸心より下方に設けることで、扱室66内からの濾過物を受網74の上方受網74aから広範囲に二番処理胴70に導くことができ、枝梗・カギ又の単粒化や藁塵の単粒化が促進される。さらに二番還元筒87の排出口87bは扱胴69の軸心とほぼ同一高さに配置しているので、扱室66内に扱室66の下方壁面から突入している二番還元筒87(図6参照)の長さを極力短くすることができ、機体前後方向で二番還元筒87の排出口87bを中板66b寄りとしているので、二番物の処理に二番処理胴70の長手方向を有効に使用でき、処理効率がよい。
Further, as shown in FIG. 6, the rotation shaft (first rotation shaft) 70 b of the second processing cylinder 70 is provided below the rotation shaft (axial center) 69 b of the handling cylinder 69, and the discharge port 87 b of the second reduction cylinder 87. Is substantially the same height as the axis of the barrel 69.
In this way, the second processing cylinder 70 is provided below the axis of the handling cylinder 69, so that the filtrate from the inside of the handling chamber 66 is guided to the second processing cylinder 70 over a wide range from the upper receiving net 74 a of the receiving net 74. It is possible to increase the size of branches, keys, and soot and soot dust. Further, since the discharge port 87 b of the second reduction cylinder 87 is disposed at substantially the same height as the shaft center of the handling cylinder 69, the second reduction cylinder 87 that enters the handling chamber 66 from the lower wall surface of the handling chamber 66. (See FIG. 6) can be made as short as possible, and the discharge port 87b of the second return cylinder 87 is closer to the middle plate 66b in the longitudinal direction of the machine body. The longitudinal direction can be used effectively, and the processing efficiency is good.

なお、図8に脱穀装置15の正面図を示し、図9には図3のB−B線矢視断面図を示し図10には図3のC−C線矢視断面図を示す。図11にはエンジン21から脱穀装置15への動力伝動機構図を示す。
エンジン21から伝達される動力が脱穀装置入力プーリ23から脱穀装置15内に伝達され(図11参照)、脱穀装置入力プーリ23から分岐した動力は揺動棚駆動軸36aを介して揺動棚51を駆動し、また脱穀装置入力プーリ23から分岐したもう一方の動力は扱胴・処理胴入力ギヤケース25を経由して回転軸69bと二番処理胴軸70bを駆動する。また揺動棚51を駆動する動力はフィードチェン駆動ギアケース14aを介してフィードチェン14を駆動する。
8 shows a front view of the threshing device 15, FIG. 9 shows a cross-sectional view taken along line BB in FIG. 3, and FIG. 10 shows a cross-sectional view taken along line CC in FIG. FIG. 11 shows a power transmission mechanism diagram from the engine 21 to the threshing device 15.
The power transmitted from the engine 21 is transmitted from the threshing device input pulley 23 into the threshing device 15 (see FIG. 11), and the power branched from the threshing device input pulley 23 is oscillated shelf 51 via the oscillating shelf drive shaft 36a. The other power branched from the threshing device input pulley 23 drives the rotary shaft 69b and the second processing cylinder shaft 70b via the handling cylinder / processing cylinder input gear case 25. The power for driving the swing shelf 51 drives the feed chain 14 via the feed chain drive gear case 14a.

扱胴69と二番処理胴70に動力伝達をする扱胴・処理胴ギアケース25は二番処理胴70の前方部に設け、ベルト伝導により扱胴69に動力分岐しているので、例えば悪条件下で扱胴部が過負荷となり扱胴69の回転がドロップするような場合でも二番物や扱胴受網74からの濾過物を処理する処理胴部は回転が円滑であり、処理量の増加にも対応できる。また、シーブ53はシーブ回動連動板53aにより、揺動棚51に一体で揺動する。   The handling cylinder / processing cylinder gear case 25 for transmitting power to the handling cylinder 69 and the second processing cylinder 70 is provided in the front part of the second processing cylinder 70 and is branched to the handling cylinder 69 by belt conduction. Even if the handling cylinder is overloaded under the conditions and the rotation of the handling cylinder 69 drops, the processing cylinder for processing the second product and the filtrate from the handling cylinder receiving net 74 rotates smoothly, and the processing amount It can cope with the increase of. Further, the sheave 53 swings integrally with the swing shelf 51 by a sheave rotation interlocking plate 53a.

扱胴69終端部下方に臨む揺動棚51の中間部上側には、ジャンプラック54を設ける。扱室66からの排塵物を、このジャンプラック54上に受けて拡散してシーブ53上へ落とすことにより、排塵物中の穀粒の回収効率を高めるものである。尚、該ジャンプラック54は、長尺のものと短尺のものとを交互に配置する。   A jump rack 54 is provided above the middle part of the swing shelf 51 facing the lower end of the handling drum 69. Dust collected from the handling chamber 66 is received on the jump rack 54, diffused, and dropped onto the sheave 53, thereby improving the collection efficiency of the grains in the dust. Note that the jump racks 54 are alternately arranged with long ones and short ones.

また、二番螺旋86の回動軸86aを駆動する二番プーリ39から横断流ファン91の駆動機構に動力伝達される。
なお、図11に示すようにエンジン21からの動力はHST28を経由して噛合式変速装置24に伝達され、クローラ4の回転駆動力が得られる。
Further, power is transmitted from the second pulley 39 that drives the rotation shaft 86 a of the second spiral 86 to the drive mechanism of the cross flow fan 91.
As shown in FIG. 11, the power from the engine 21 is transmitted to the meshing transmission 24 via the HST 28, and the rotational driving force of the crawler 4 is obtained.

図12に受網74の構成図を示すように、本実施例では扱胴69の上方受網74aと下方受網74bの目合をそれぞれ異ならせ、上方受網74aの目合を下方受網74bの目合よりも大きくするとともに、上方受網74aの目合は機体前後方向で互いに異ならせ、後方部の目合を前方部よりも大きくしている。上方受網74aの機体前方の目合が比較的小さい受網74aaとし、上方受網74aの機体後方の目合比較的大きい受網74abとし、受網74abでは枝梗粒などが通過し易い目合いの大きさとした。 As shown in the block diagram of the receiving net 74 in FIG. 12, in this embodiment, the upper receiving net 74a and the lower receiving net 74b of the handling cylinder 69 have different meshes, and the upper receiving net 74a has a lower mesh. The mesh of 74b is made larger, and the mesh of the upper receiving net 74a is made different from each other in the longitudinal direction of the machine body so that the mesh of the rear part is made larger than the front part. The upper receiving net 74a is a receiving net 74aa having a relatively small mesh size in front of the machine body, and the upper receiving net 74a is a receiving net 74ab having a relatively large mesh size behind the machine body. The size of the mesh.

受網74aaはクリンプ網部74aa1と仕切板74aa2からなり、受網74abは銅線部74ab1と仕切板74ab2からなる。クリンプ網部74aa1の一辺の長さをAとし、仕切板74ab2同士の間隔をBとし、銅線部74ab1同士の間隔をCとすると以下の大きさの関係が成り立つようにする。
A<B<C
The receiving net 74aa includes a crimp net 74aa1 and a partition plate 74aa2, and the receiving net 74ab includes a copper wire portion 74ab1 and a partition plate 74ab2. When the length of one side of the crimp net portion 74aa1 is A, the interval between the partition plates 74ab2 is B, and the interval between the copper wire portions 74ab1 is C, the following relationship is established.
A <B <C

このように、扱室前方側のクリンプ網部74aa1の濾過孔部を正方形とし、後方側の受網74abの濾過孔部を長方形として、濾過孔部の縦・横比を変化させることで濾過量を増加あるいは抑制することが容易にできる構成となる。また、受網74abの濾過孔部を長方形とし、機体前後方向の濾過孔の長さより上下方向の濾過孔の長さを大きくしているので、受網74の回転(周速)により受網74からの処理物の濾過が促進され、処理物の濾過性能が従来より向上する。   In this way, the filtration hole portion of the crimping net portion 74aa1 on the front side of the handling chamber is square, the filtration hole portion of the rear receiving net 74ab is rectangular, and the amount of filtration is changed by changing the aspect ratio of the filtration hole portion. It becomes the structure which can increase or suppress easily. Further, since the filtering hole portion of the receiving net 74ab is rectangular and the length of the filtering hole in the vertical direction is larger than the length of the filtering hole in the longitudinal direction of the machine body, the receiving net 74 is rotated by the rotation (peripheral speed) of the receiving net 74. Filtration of the processed product from the water is promoted, and the filtration performance of the processed product is improved as compared with the prior art.

また、板体で構成され、複数個軸心方向に並列配置される仕切板74ab2は銅線部74ab1より扱胴69の軸心方向に突出しているので、処理物の濾過が従来以上に向上する。さらに仕切板74ab2は扱歯69aの先端部とオーバーラップしている(図6参照)ので、扱室66内の処理物の流れに抵抗を加えることができ、処理物の濾過を促進し、さらに圧力を加えられることにより単粒化(カギ又の分離や枝梗の除去)が行える。   Further, since the partition plates 74ab2 formed of a plate body and arranged in parallel in the axial direction protrude from the copper wire portion 74ab1 in the axial direction of the handling cylinder 69, the filtration of the processed material is improved more than before. . Furthermore, since the partition plate 74ab2 overlaps the tip of the tooth handling 69a (see FIG. 6), it is possible to add resistance to the flow of the processed material in the processing chamber 66, promote filtration of the processed material, By applying pressure, it can be made into single grains (separation of keys or branches and removal of branch limbs).

また、上方受網74aの前方の仕切板74aa2の突出代より、受網74後方の仕切板74ab2の突出代を小さくしているので扱室66内での送塵を止めて抵抗を加えることがなく、扱室66内での過負荷や異音発生などの不具合の発生を防いでいる。   Further, since the protruding margin of the partition plate 74ab2 behind the receiving net 74 is smaller than the protruding margin of the partition plate 74aa2 in front of the upper receiving net 74a, it is possible to add resistance by stopping dust feeding in the handling chamber 66. In addition, the occurrence of problems such as overload and abnormal noise generation in the handling chamber 66 is prevented.

また、扱胴69周辺の受網74を通過する量は扱胴69の上方部位より下方部位の方が多いので、上方受網74aの目合を下方受網74bの目合より大きくすることで、処理物の濾過効率を従来より向上させ、さらに扱胴69の後方部の目合を拡大することで扱胴69でこなされ、ある程度単粒化が行われた穀粒を扱室66より濾過することができ、穀粒の処理効率が従来よりさらに高まることとなる。さらに受網74の上方部からの濾過物を処理胴70に導くことで穀粒の単粒化が促進され、選別状態を良好にしながら処理能力の拡大が行える。   Further, since the amount passing through the receiving net 74 around the handling cylinder 69 is larger in the lower part than the upper part of the handling cylinder 69, the mesh of the upper receiving net 74a is made larger than the mesh of the lower receiving net 74b. In addition, the filtration efficiency of the processed material is improved as compared with the conventional method, and further, the grain at the rear part of the handling cylinder 69 is expanded to be processed by the handling cylinder 69, and the grains that have been made to a certain degree are filtered from the handling chamber 66. It is possible to increase the processing efficiency of the grain. Further, by introducing the filtrate from the upper part of the receiving net 74 to the processing cylinder 70, the unigraining of the grain is promoted, and the processing capacity can be expanded while improving the selection state.

二番還元筒87の螺旋87aの回転方向は上方より見て反時計廻りとするとともに排出口87bに案内板87d(図5)を設け、下方の二番処理胴70に処理物を導き易くしている。
二番還元筒87の螺旋87aの回転方向を時計廻りとすると、処理物が湿材である場合は、処理物が機枠側壁に張り付き、ブリッジを起こし、処理物の搬送に支障をきたすおそれがある。そこで螺旋87aの回転方向を反時計廻りとすることで、扱胴69のある方向に処理物を導き、上記した不具合が発生しないようにする。
The direction of rotation of the spiral 87a of the second reduction cylinder 87 is counterclockwise when viewed from above, and a guide plate 87d (FIG. 5) is provided at the discharge port 87b, so that the processed material can be easily guided to the second processing cylinder 70 below. ing.
If the direction of rotation of the spiral 87a of the second reduction cylinder 87 is clockwise, when the processed material is a wet material, the processed material may stick to the side wall of the machine frame and cause a bridge, which may hinder the conveyance of the processed material. is there. Therefore, by setting the direction of rotation of the spiral 87a counterclockwise, the processed material is guided in the direction in which the handling cylinder 69 is present, so that the above-described problems do not occur.

また、排出口87bに設けた案内板87dは、二番還元筒87から排出中の処理物を誘導して容易に下方の二番処理胴70に導くことができる。このため、二番物が受網74から扱室66内に侵入することを防止して扱胴69の負荷が増加することを防ぎ、処理物が二番処理胴70の終端部(機体前方)側に直接飛散することも防止することができる。   Further, the guide plate 87d provided at the discharge port 87b can guide the processed material being discharged from the second reduction cylinder 87 and easily guide it to the lower second processing cylinder 70. For this reason, the second object is prevented from entering the handling chamber 66 from the receiving net 74 and the load on the handling cylinder 69 is prevented from increasing, and the processed object is the terminal end (front side of the machine body) of the second processing cylinder 70. Direct scattering to the side can also be prevented.

二番処理胴70の螺旋70aの送塵方向は機体後方から機体前方に向き、二番処理胴70の前端部に該処理胴70からの排出部(排出羽根部)を設けている。
そのため、小型の脱穀装置では、扱室66内の扱胴69の長さが短く、扱室66内の処理物の回収時間が短く、高効率化が困難であったが、二番処理胴70の送塵方向を機体後方から前方へとすることで、二番処理物を揺動棚51の前方部に還元でき、揺動棚51での処理物の回収が良好に行われ、揺動棚51の前方部での浮遊選別距離も長く行える。
また、処理胴70の終端部に排出羽根部87cを設けることで、揺動棚51上の処理物の均分化も促進されることとなる。
The dust feeding direction of the spiral 70a of the second processing cylinder 70 is directed from the rear of the machine body to the front of the machine body, and a discharge part (discharge blade part) from the processing cylinder 70 is provided at the front end of the second processing cylinder 70.
Therefore, in the small threshing apparatus, the length of the handling cylinder 69 in the handling chamber 66 is short, the collection time of the processed material in the handling chamber 66 is short, and high efficiency is difficult. By changing the dust feeding direction from the rear to the front of the machine body, the second processed material can be returned to the front part of the swing shelf 51, and the recovered product can be collected well on the swing shelf 51. The floating selection distance in the front part of 51 can also be made long.
Further, by providing the discharge blade portion 87c at the terminal end of the processing cylinder 70, the leveling of the processed material on the swing shelf 51 is also promoted.

また、二番処理胴70の下方には処理物の搬送を案内する無孔のガイド板(盲板)75を設けるとともに、図13に選別室50の平面図を示すように、平面視においてガイド板75の前端は揺動棚51上の寄せ板88より前方に設けている。   In addition, a non-porous guide plate (blind plate) 75 that guides the conveyance of the processed material is provided below the second processing cylinder 70, and the guide is shown in a plan view as shown in a plan view of the sorting chamber 50 in FIG. The front end of the plate 75 is provided in front of the alignment plate 88 on the swing shelf 51.

処理物の搬送樋となる無孔のガイド板75を設けることで二番処理胴70での処理物の処理が良好に行われ、機体前方へと送塵されるが、ガイド板75の前端より揺動棚51上の寄せ板88を後方とすることで、二番処理胴70から多量の処理物が揺動棚51上に送られてきても処理物の均分化が促進され、揺動棚51の処理物の回収が良好に行われる。   By providing a non-porous guide plate 75 that serves as a transport rod for the processed material, the second processed cylinder 70 can be processed satisfactorily and sent to the front of the machine body, but from the front end of the guide plate 75 By setting the gathering plate 88 on the rocking shelf 51 to the rear, even if a large amount of processed material is sent from the second processing cylinder 70 onto the rocking shelf 51, the leveling of the processed material is promoted. Recovery of the 51 processed products is performed well.

図14(a)のコンバインの正面図と図14(b)のコンバインの左側面図に示し、扱胴・処理胴入力ギアケース25の構造図を図15に示す。図15(a)は外観図であり、図15(b)は図15(a)のS1−S1線断面矢視図であり、図15(c)は図15(a)のS2−S2線断面矢視図である。図14(a)、図14(b)に示すように扱胴・処理胴入力ギアケース25は脱穀装置15の前方右方にあり、エンジン21からの冷却風路上に設けている。   FIG. 14A is a front view of the combine in FIG. 14A and a left side view of the combine in FIG. 14B, and FIG. 15 is a structural diagram of the handling cylinder / processing cylinder input gear case 25. 15A is an external view, FIG. 15B is a sectional view taken along the line S1-S1 in FIG. 15A, and FIG. 15C is a line S2-S2 in FIG. 15A. It is a cross-sectional arrow view. As shown in FIGS. 14 (a) and 14 (b), the handling cylinder / processing cylinder input gear case 25 is located on the front right side of the threshing device 15 and is provided on the cooling air passage from the engine 21.

エンジン21からの動力で駆動する入力プーリ32aが固着した入力軸32の先端にベベルギア32bが設けられ、該ベベルギア32bと噛合するカウンタ軸33の一端部にあるベベルギア33aにエンジン動力が伝達され、該カウンタ軸33の他端部に並列配置されたギア33c、33bと噛合するギア34a、35aを介してそれぞれ扱胴出力軸34と処理胴出力軸35とが駆動され、それぞれ扱胴出力プーリ34bと図15には示していない二番処理胴軸70bに動力伝達される。   A bevel gear 32b is provided at the tip of an input shaft 32 to which an input pulley 32a that is driven by power from the engine 21 is fixed, and engine power is transmitted to a bevel gear 33a at one end of a counter shaft 33 that meshes with the bevel gear 32b. The barrel output shaft 34 and the processing barrel output shaft 35 are driven through gears 34a and 35a meshing with gears 33c and 33b arranged in parallel to the other end of the counter shaft 33, respectively. Power is transmitted to the second processing cylinder shaft 70b not shown in FIG.

また入力軸32にはオイルシール37を挟んで外方ベアリング40と内方ベアリング41が設けられ、入力軸部32は外方ベアリング40と内方ベアリング41によりギアケース25に支持されている。内方ベアリング41は通常のベアリングであるが、外方ベアリング40はグリースを封入した自己潤滑ベアリングである。また外方ベアリング40と内方ベアリング41の外側には止め輪42,43をそれぞれ配置しているのでベアリング40,41のスラスト荷重を止め輪42,43で受け止めることができる。   The input shaft 32 is provided with an outer bearing 40 and an inner bearing 41 with an oil seal 37 interposed therebetween, and the input shaft portion 32 is supported by the gear case 25 by the outer bearing 40 and the inner bearing 41. The inner bearing 41 is a normal bearing, while the outer bearing 40 is a self-lubricating bearing filled with grease. Further, since the retaining rings 42 and 43 are disposed outside the outer bearing 40 and the inner bearing 41, the thrust load of the bearings 40 and 41 can be received by the retaining rings 42 and 43.

上述のように扱室66内の負荷によるギアケース25内の油温の上昇を抑え、エンジン21からの冷却風で空冷効果を持たせることで操作席20の熱気上昇やギアケース25の油温上昇によるベアリング40,41やギア群の潤滑性能低下による寿命の低下を防止するが、自己潤滑ベアリングである外方ベアリング40を冷却風路側とし、冷却効果を大きくすることで高温運転によるベアリング40,41のグリスの流出を抑え高寿命を達成できる。   As described above, an increase in oil temperature in the gear case 25 due to a load in the handling chamber 66 is suppressed, and an air cooling effect is provided by cooling air from the engine 21, thereby increasing the hot air in the operation seat 20 and the oil temperature in the gear case 25. The life of the bearings 40, 41 and the gear group due to the rise is prevented from being shortened due to a decrease in the lubrication performance. However, the outer bearing 40, which is a self-lubricating bearing, is used as the cooling air passage side. The long life can be achieved by suppressing the outflow of 41 grease.
