特開平１１−２７５９３９号公報JP 11-275939 A

従来の脱穀機にあっては、脱穀処理物を後側縦桟部材による案内で受網後端側に向かって旋回流動させるものである。しかし、受網を構成する縦桟部材の傾斜による案内では、十分な送り作用を得難く、脱穀処理物が滞留することがあった。殊に、脱穀対象物が麦の如く長稈であるなど、扱室に穀稈のボリュームが大になると、送り作用が足りず、脱穀処理物の詰まりが生じることがあった。   In the conventional threshing machine, the threshing product is swirled and flowed toward the rear end side of the receiving net by the guide by the rear vertical rail member. However, in the guidance by the inclination of the vertical beam members constituting the receiving net, it is difficult to obtain a sufficient feeding action, and the threshing product may stay. In particular, when the volume of cereals in the handling room becomes large, such as when the threshing object is long like wheat, the feeding action is insufficient, and the threshing product may be clogged.

本発明の目的は、受網に簡単な対策を施すものでありながら、脱穀処理物を処理方向終端側へ確実に搬送できる脱穀装置を提供することにある。   The objective of this invention is providing the threshing apparatus which can convey a threshing processed material reliably to the process direction termination | terminus side, providing a simple countermeasure for a receiving network.

本発明による脱穀装置は、
扱室に扱胴軸芯まわりに回転自在に支持された扱胴と、前記扱胴の外周囲に配備された受網とを備え、
前記受網の前記扱胴側の面に、扱胴周方向に対して傾斜する状態で設けられ、かつ、脱穀処理物を処理方向終端側へ送る送り部材を備え、
前記扱胴の外周部のうち、扱歯の取付け箇所以外の部位に設けられ、脱穀処理物を処理方向終端側へ送る送り羽根を備え、
前記送り部材は、前記扱胴の処理方向始端部から処理方向終端部に向かう螺旋状に巻かれるように設けられ、
前記送り羽根は、前記扱胴の処理方向始端部から処理方向終端部に向かう螺旋状に巻かれるように、扱胴周方向において間欠的に設けられ、
前記送り羽根の螺旋巻き間隔は、前記送り部材の螺旋巻き間隔よりも小さく設定されていることを特徴とする。 The threshing device according to the present invention comprises:
A handling cylinder supported rotatably around the axis of the handling cylinder in the handling chamber, and a receiving net disposed on the outer periphery of the handling cylinder,
Provided on the surface of the receiving net of the receiving net in a state inclined with respect to the circumferential direction of the handling cylinder, and comprising a feeding member that sends the threshing processed product to the end side in the processing direction,
Of the outer periphery of the treatment drum, provided in a portion other than the attachment portion of the tooth treatment, comprising a feed blade that sends the threshing processed product to the processing direction end side ,
The feeding member is provided so as to be wound in a spiral shape from the processing direction start end of the handling cylinder toward the processing direction end.
The feed blade is intermittently provided in the circumferential direction of the barrel so that it is spirally wound from the processing direction start end of the handling barrel toward the processing direction end.
The spiral winding interval of the feeding blade is set to be smaller than the spiral winding interval of the feeding member .

本構成によると、送り部材が受網の脱穀作用面に位置しているので、扱胴によって回動力を付与された脱穀処理物が送り部材に触れ易い。そして、送り部材は、触れた脱穀処理物を処理方向終端側に向かうよう案内するから、扱室に供給された脱穀処理物が多くても、脱穀処理物を処理方向終端側に向かわせ易い。   According to this structure, since the feed member is located on the threshing action surface of the receiving net, the threshing product to which the rotational force is applied by the handling cylinder is easy to touch the feed member. And since a feed member guides the threshing processed material which touched it to go to the process direction termination | terminus side, even if there are many threshing processed products supplied to the treatment room, it is easy to make a threshing processed product face the processing direction termination | terminus side.

従って、本発明によると、送り部材を受網の脱穀作用面に備えるだけの簡単な対策を施すものでありながら、麦の如き長稈の穀稈を脱穀処理するなど、扱室に供給される穀稈のボリュームが大になる場合でも、扱室における脱穀処理物の滞留を効果的に抑制して、円滑にかつ良好な脱穀精度で脱穀処理できる。   Therefore, according to the present invention, while providing a simple measure to provide the feeding member on the threshing action surface of the receiving net, it is supplied to the handling room such as threshing a long culm such as wheat. Even when the volume of the cereal is large, the threshing treatment can be smoothly suppressed with good threshing accuracy by effectively suppressing the retention of the threshing product in the handling room.

It is easy to replace and repair the feeding member.

本発明において、前記受網を、前記扱胴軸芯方向及び扱胴周方向において、複数の分割受網に分割自在に構成し、前記送り部材を、前記複数の分割受網に各別に支持された分割送り部材に分割自在に構成し、少なくとも一部の前記分割送り部材が互いに連なるように構成してあると好適である。   In the present invention, the receiving net is configured to be divided into a plurality of divided receiving nets in the handling cylinder axis direction and the handling cylinder circumferential direction, and the feeding member is supported by the plurality of divided receiving nets. It is preferable that the divided feeding members are configured so as to be separable and at least some of the divided feeding members are connected to each other.

本構成によると、受網を扱胴軸芯方向及び扱胴周方向の一方だけにおいて複数の分割受網に分割自在に構成した場合に比べ、分割受網の形状をより取扱い易い形状にできて、送り部材を分割送り部材に分割して分割受網と共に脱穀部から取出すのにより容易に取出すことができ、送り部材の交換や修理をより行ない易い。   According to this configuration, compared to the case where the receiving net is configured to be divided into a plurality of divided receiving nets only in one of the handling cylinder axis direction and the handling cylinder circumferential direction, the shape of the divided receiving net can be made easier to handle. The feeding member can be easily taken out by dividing the feeding member into divided feeding members and taking out from the threshing portion together with the divided receiving net, and the feeding member can be easily replaced or repaired.

本発明において、前記複数の分割受網それぞれの配置を入れ替えても、前記複数の分割受網が前記受網を形成するように、前記複数の分割受網を構成し、前記複数の分割受網それぞれに前記分割送り部材を支持し、前記複数の分割受網それぞれの配置を入れ替えた状態において、少なくとも一部の前記分割送り部材が互いに連なるように構成してあると好適である。   In the present invention, the plurality of divided receiving networks are configured such that the plurality of divided receiving networks form the receiving network even if the arrangement of each of the plurality of divided receiving networks is changed. It is preferable that at least some of the divided feeding members are connected to each other in a state where the divided feeding members are supported respectively and the arrangement of the plurality of divided receiving nets is changed.

本構成によると、一部の分割送り部材に磨滅が発生した際、磨滅が発生した分割送り部材を支持する分割受網を他の分割受網と入れ替えることにより、磨滅した分割送り部材を別の分割送り部材と入れ替えることができ、分割受網の配置を入れ替えるだけで簡単に送り部材の交換ができて有利である。   According to this configuration, when some of the divided feeding members are worn, the divided divided feeding members that support the divided feeding members that have been worn out are replaced with other divided receiving nets. It can be replaced with the divided feeding member, and it is advantageous that the feeding member can be easily replaced simply by changing the arrangement of the divided receiving nets.

本構成によると、扱胴と受網との間の扱き処理空間に対して内部空間が支持バーどうしの間を介して連通する。従って、扱胴は、受網との間の扱き処理空間に位置する脱穀処理物に支持バー及び扱歯の打撃による脱穀処理を施し、この脱穀処理で得た処理物が内部空間へ入り込むことを許容し、扱き処理空間の処理物と内部空間の処理物とを攪拌しながら、これらの処理物に支持バー及び扱歯の打撃による脱穀処理を施す。つまり、大ボリュームの脱穀処理物であっても、脱穀負荷が著しく増大することを防止しながらスムーズに脱穀処理できる。   According to this configuration, the internal space communicates with the handling processing space between the handling cylinder and the receiving net through the support bars. Therefore, the handling cylinder performs the threshing process by striking the support bar and the tooth-handling on the threshing processed product located in the handling processing space between the receiving net and the processed product obtained by this threshing process entering the internal space. While allowing the processed material in the handling space and the processed material in the internal space to be agitated, these processed materials are subjected to a threshing process by striking the support bar and the teeth. That is, even a large-volume threshing product can be threshed smoothly while preventing the threshing load from significantly increasing.

刈取搬送部４について説明する。
刈取搬送部４は、車体の走行に伴って、その前部の左右両端に配備したデバイダ１４によって未刈り穀稈を収穫対象の穀稈と収穫対象外の穀稈とに梳き分ける。又、刈取搬送部４の前部上方に配備した回転リール１５によって収穫対象穀稈の穂先側を後方に向けて掻き込み、刈取搬送部４の底部に装備したバリカン型の刈取装置１６によって収穫対象穀稈の株元側を切断して、収穫対象の穀稈を刈り取る。そして、刈取装置１６の後方に配備した横送オーガ１７によって刈取り穀稈を左右方向の所定箇所に寄せ集めて後方に送り出し、その所定箇所から脱穀装置５にわたって架設されたフィーダ１８によって刈取り穀稈を脱穀装置５に供給する。 The cutting and conveying unit 4 will be described.
As the vehicle body travels, the cutting and conveying unit 4 separates the uncut cereals into cereals that are to be harvested and cereals that are not to be harvested by the dividers 14 provided at the left and right ends of the front part. Further, the rotary reel 15 provided above the front part of the cutting and conveying unit 4 is raked back with the tip side of the harvested grain culm backward, and the harvesting target is harvested by the clipper-type cutting device 16 provided at the bottom of the cutting and conveying unit 4. Cut the grain side of the grain and harvest the harvested grain. Then, the harvested cereals are gathered to a predetermined place in the left-right direction by the lateral feed auger 17 arranged at the rear of the reaping device 16 and fed backward, and the cereals are harvested by the feeder 18 installed over the threshing device 5 from the predetermined place. The threshing device 5 is supplied.

昇降シリンダ１９は、操縦レバー１００の前後方向への揺動操作に基づいて伸縮作動するように構成してある。つまり、操縦レバー１００を前後方向に揺動操作して昇降シリンダ１９を伸縮作動させることにより、未刈り穀稈に対する刈取装置１６の高さ位置を変更する刈り高さ調節などを行なうことができる。   The elevating cylinder 19 is configured to expand and contract based on a swinging operation of the control lever 100 in the front-rear direction. That is, by adjusting the height of the reaping device 16 relative to the uncut grain cereal, it is possible to adjust the cutting height by swinging the control lever 100 in the front-rear direction to extend and retract the lifting cylinder 19.

回転リール１５について説明する。
図１に示すように、回転リール１５の周方向での６箇所に、収穫対象穀稈の穂先側を後方に掻き込み処理する掻込み部１５Ａが設けられている。 The rotating reel 15 will be described.
As shown in FIG. 1, at six locations in the circumferential direction of the rotary reel 15, there are provided scoring portions 15 </ b> A for scrambling the ear tip side of the harvesting target culm backward.

図２２は、回転リール１５の掻込み部１５Ａを示す正面図である。図２２に示すように、掻込み部１５Ａは、回転リール１５の左右一対のリール本体１５Ｂに横架された車体横向きのタイン支軸１１０を備えている。タイン支軸１１０には、タイン支軸１１０の軸芯方向に所定間隔を空けて並んだ複数のタイン１１１を支持してある。全てのタイン１１１の背後にわたって車体横向きの掻込みガイド杆１１２を位置させてある。   FIG. 22 is a front view showing the scraping portion 15 </ b> A of the rotary reel 15. As shown in FIG. 22, the take-in portion 15 </ b> A includes a vehicle body lateral tine support shaft 110 that is horizontally mounted on a pair of left and right reel bodies 15 </ b> B of the rotary reel 15. The tine support shaft 110 supports a plurality of tines 111 arranged at predetermined intervals in the axial direction of the tine support shaft 110. A scraping guide rod 112 facing the vehicle body is positioned behind all the tines 111.

丈が短い大豆など、豆類を収穫する際、タイン１１１だけで掻き込み処理しようとすると、穀稈がタイン１１１から外れて刈残りが発生することがある。掻込みガイド杆１１２は、掻き込み処理しようとする穀稈の抜け外れを抑制し、穀稈の掻き込み性能を向上して刈残しを防止する。掻込みガイド杆１１２は、丸棒材によって構成してある。掻込みガイド杆１１２は、縦断面形状が六角や四角形の棒部材、あるいはアングル材、あるいは管部材によって構成してもよい。   When harvesting beans such as soybeans having a short length, if the tine 111 is used for a scraping process, the cereal pods may be detached from the tine 111 and a cutting residue may be generated. The scraping guide rod 112 suppresses the detachment of the culm to be scraped, improves the scraping performance of the culm and prevents uncut residue. The take-in guide rod 112 is made of a round bar. The take-in guide rod 112 may be formed of a hexagonal or quadrangular bar member, an angle member, or a tube member having a longitudinal cross-sectional shape.

掻込みガイド杆１１２は、タイン支軸１１０の両端部から一体回転するように延出した左右一対の支持アーム１１３に支持されている。タイン支軸１１０は、回転リール１５の回転にかかわらず、タイン１１１が常に下向き姿勢になるように回転リール１５の回転に連動させて回転操作される。従って、掻込みガイド杆１１２は、回転リール１５の回転にかかわらず、タイン１１１の先端部の背後側近くに位置するように操作され、所定の掻き込み処理を行なう。   The take-in guide rod 112 is supported by a pair of left and right support arms 113 extending so as to rotate integrally from both ends of the tine support shaft 110. The tine support shaft 110 is rotated in conjunction with the rotation of the rotary reel 15 so that the tine 111 always has a downward posture regardless of the rotation of the rotary reel 15. Therefore, regardless of the rotation of the rotary reel 15, the scraping guide rod 112 is operated so as to be located near the rear side of the tip of the tine 111, and performs a predetermined scraping process.

左右の支持アーム１１３に伸縮調節部１１３ａを備えてある。伸縮調節部１１３ａによって支持アーム１１３の長さ調節をすることにより、掻込みガイド杆１１２のタイン１１１に対する位置をタイン１１１の長さ方向に変更できる。   The left and right support arms 113 are provided with expansion / contraction adjustment portions 113a. By adjusting the length of the support arm 113 by the expansion / contraction adjustment portion 113 a, the position of the scraping guide rod 112 with respect to the tine 111 can be changed in the length direction of the tine 111.

伸縮調節部１１３ａに替え、支持アーム１１３の長手方向に並ぶ複数の支持孔や支持フックを支持アーム１１３に設け、複数の支持孔や支持フックに掻込みガイド杆１１２を付け替えて、支持アーム１１３における掻込みガイド杆１１２の取付位置を変更する構成を採用することにより、掻込みガイド杆１１２のタイン１１１にタインに対する位置変更を可能にして実施してもよい。   A plurality of support holes and support hooks arranged in the longitudinal direction of the support arm 113 are provided in the support arm 113 in place of the expansion / contraction adjustment unit 113a, and the guide guide rod 112 is replaced with the plurality of support holes and support hooks. By adopting a configuration in which the attachment position of the scraping guide rod 112 is changed, the tine 111 of the scraping guide rod 112 may be changed in position with respect to the tine.

掻込みガイド杆１１２は、支持アーム１１３に脱着自在に支持し、不要時には取り外せるように構成してある。掻込みガイド杆１１２を支持アーム１１３と共にタイン支軸１１０に対して着脱するように構成してもよい。   The take-in guide rod 112 is detachably supported by the support arm 113, and can be removed when not needed. The take-in guide rod 112 may be configured to be attached to and detached from the tine support shaft 110 together with the support arm 113.

A plate member constituting the start-up end 41 of the spiral blade 40 is connected to the upper end of the spiral blade main body 43 in the scraping direction. A reinforcing member 45 as a liner that forms the scraping action surface 44 of the spiral blade 40 is attached to the side surface of the spiral blade body 43. The reinforcing member 45 has an abrasion resistance surface superior to that of the spiral blade body 43 and forms a scratching action surface 44 that is harder to wear than the spiral blade body 43. A support 43 a that increases the support strength of the spiral blade 40 is attached across the side surface of the spiral blade body 43 opposite to the side of the scratching action surface 44 and the outer peripheral surface of the scraping portion 39. The support body 43 a is configured by a band plate along the radial direction of the scraping portion 39.

図７，８に示すように、掻込み始端部４１を構成する板部材は、螺旋羽根本体４３の掻き込み方向上手側端部と、掻込み部３９の外周面とにわたって連結してある。図８に示すように、掻込み始端部４１を構成する板部材と螺旋羽根本体４３とは、板部材を掻込み作用面４４に当て付けた状態で、２本の連結ボルト４６と、一つの雌ネジ部材４８とによる締結によって連結してある。   As shown in FIGS. 7 and 8, the plate member constituting the scraping start end portion 41 is connected across the scraping direction upper end portion of the spiral blade main body 43 and the outer peripheral surface of the scraping portion 39. As shown in FIG. 8, the plate member and the spiral blade body 43 constituting the start-up end portion 41 are in a state where the plate member is applied to the drive-in action surface 44, They are connected by fastening with the female screw member 48.

一つの雌ネジ部材４８は、２つの雌ネジ孔４８ａを備えた状態で、螺旋羽根４０の掻込み作用面４４が位置する側に配置してある。螺旋羽根本体４３、補強部材４５、及び、掻込み作用面４４を形成する板部材にはネジ山が無いボルト孔を設けてある。２つの連結ボルト４６は、螺旋羽根４０に対して掻込み作用面４４の側とは反対側から螺旋羽根本体４３、補強部材４５及び板部材のボルト孔に装着し、一つの雌ネジ部材４８の雌ネジ孔４８ａに装着して雌ネジ部材４８に締結してある。従って、２つの連結ボルト４６それぞれの頭部４６ａは、螺旋羽根４０の背後側に位置し、脱穀処理物に接触し難くい。雌ネジ部材４８は、連結ボルト４６の軸芯に沿う方向視での形状が小判形となるように構成してある。雌ネジ部材４８は、螺旋羽根４０の掻込み作用面４４の側に位置して脱穀処理物に接触し易いが、２つの連結ボルト４６に各別に装着するナットに比して大きな形状を備えるので磨滅し難い。   One female screw member 48 is arranged on the side where the scraping action surface 44 of the spiral blade 40 is located, with two female screw holes 48a. The plate member forming the spiral blade main body 43, the reinforcing member 45, and the scraping action surface 44 is provided with a bolt hole having no thread. The two connecting bolts 46 are attached to the spiral blade main body 43, the reinforcing member 45, and the bolt holes of the plate member from the side opposite to the side of the scratching action surface 44 with respect to the spiral blade 40.

図１５（ａ）は、第１の送り部材条Ｊ１の処理方向始端側の部分に位置する送り部材５７ａ、及び第２の送り部材条Ｊ２の処理方向始端側の部分に位置する送り部材５７ｂ以外の送り部材５７を示す平面図である。図１５（ｂ）は、第１の送り部材条Ｊ１の処理方向始端側の部分に位置する送り部材５７ａ、及び第２の送り部材条Ｊ２の処理方向始端側の部分に位置する送り部材５７ｂ以外の送り部材５７を示す背面図である。   FIG. 15A shows a feed member 57a positioned at the processing direction start end portion of the first feed member strip J1 and a feed member 57b positioned at the processing direction start end portion of the second feed member strip J2. It is a top view which shows the feed member 57 of this. FIG. 15B shows a feed member 57a positioned at the processing direction start end portion of the first feed member strip J1 and a feed member 57b positioned at the processing direction start end portion of the second feed member strip J2. It is a rear view which shows the feed member 57 of this.

図９，１２，１５に示すように、各送り部材５７，５７ａ，５７ｂは、板状の送り作用部５８を備えている。送り作用部５８の送り方向上手側及び送り方向下手側に連結部６０，６５，７５を備えてある。送り作用部５８の送り作用面５８ａが位置する側と反対側である背面側に、送り作用部５８の長手方向に長い板状の補強リブ８１を付設してある。送り部材５７ａは、送り作用部５８が送り方向下手側の連結部６５，７５よりも処理物送り方向下手側に位置し、連結部６５，７５を送り作用部５８によって処理物が接触しにくいようにカバーするよう構成してある。   As shown in FIGS. 9, 12, and 15, the feeding members 57, 57 a, and 57 b each include a plate-like feeding action portion 58. Connecting portions 60, 65, 75 are provided on the upper side in the feed direction and the lower side in the feed direction of the feed action portion 58. A plate-like reinforcing rib 81 that is long in the longitudinal direction of the feed action portion 58 is attached to the back side of the feed action portion 58 opposite to the side on which the feed action surface 58a is located. In the feed member 57a, the feed action portion 58 is located on the lower side in the workpiece feed direction with respect to the connection portions 65 and 75 on the lower side in the feed direction so that the workpieces are less likely to come into contact with the feed action portion 58. It is configured to cover.

図３，５に示すように、第１の送り部材条Ｊ１の処理方向始端側の部分に位置する送り部材５７ａ、及び第２の送り部材条Ｊ２の処理方向始端側の部分に位置する送り部材５７ｂは、送り方向上手側の連結部６０によって螺旋羽根４０に支持し、送り方向下手側の連結部６５によって扱歯５５に支持するように構成してある。   As shown in FIGS. 3 and 5, the feed member 57a located at the processing direction start end portion of the first feed member strip J1, and the feed member positioned at the processing direction start end portion of the second feed member strip J2. 57b is configured to be supported on the spiral blade 40 by the connecting portion 60 on the upper side in the feeding direction and to be supported on the tooth handling 55 by the connecting portion 65 on the lower side in the feeding direction.

図１０，１３，１８に示すように、送り部材５７ａ及び送り部材５７ｂの送り方向上手側の連結部６０は、送り作用部５８に設けた二つのネジ山が無いボルト孔６１を備え、二本の連結ボルト６２と一つの雌ネジ部材６３とによって送り作用部５８を螺旋羽根４０に締結し、これによって送り部材５７ａの送り方向上手側端部を螺旋羽根４０に支持するように構成してある。   As shown in FIGS. 10, 13, and 18, the connecting portion 60 on the upper side in the feeding direction of the feeding member 57 a and the feeding member 57 b includes two bolt holes 61 provided in the feeding action portion 58 and without two threads. The connecting bolt 62 and one female screw member 63 are used to fasten the feed action portion 58 to the spiral blade 40, thereby supporting the upper end of the feed member 57 a in the feed direction on the spiral blade 40. .

すなわち、送り方向上手側の連結部６０は、送り作用部５８を螺旋羽根４０の掻き込み方向下手側端部における背面側に当て付け、送り作用部５８の二つのボルト孔６１、及び、螺旋羽根４０に設けた二つのネジ山が無いボルト孔それぞれに、連結ボルト６２を螺旋羽根４０に対して螺旋羽根４０の掻込み作用面４４が位置する側とは反対側から装着し、この二本の連結ボルト６２を、螺旋羽根４０の掻き込み作用面側に位置させた一つの雌ネジ部材６３が有する二つの雌ネジ孔６３ａに装着して締め付けることにより、送り作用部５８を螺旋羽根４０に締結する。   That is, the connecting portion 60 on the upper side in the feeding direction applies the feeding action portion 58 to the back side at the lower end in the scraping direction of the spiral blade 40, the two bolt holes 61 of the feeding action portion 58, and the spiral blade In each of the two bolt holes with no thread provided in 40, a connecting bolt 62 is mounted on the spiral blade 40 from the side opposite to the side where the spiraling action surface 44 of the spiral blade 40 is located. The feeding action part 58 is fastened to the spiral blade 40 by attaching and tightening the connecting bolt 62 to the two female screw holes 63a of the single female screw member 63 located on the side of the spiraling action surface of the spiral blade 40. To do.

従って、連結ボルト６２の頭部６２ａは、送り部材５７ａ，５７ｂ及び螺旋羽根４０の背面側に位置し、脱穀処理物に触れにくい。雌ネジ部材６３の連結ボルト６２の軸芯方向での面積が各連結ボルト６２に装着されるナットに比して広いものとなる。これにより、雌ネジ部材６３は、脱穀処理物に接触し易いが、連結ボルト６２よりも磨滅し難い。   Therefore, the head 62a of the connecting bolt 62 is located on the back side of the feed members 57a and 57b and the spiral blade 40 and is difficult to touch the threshing processed product.

送り部材９１について詳述する。
送り部材９１は、受網２７の縦桟８５及び横桟８６よりも扱胴側に突出し、かつ、扱胴２１の扱歯５５の先端での回転軌跡Ｔ（図３，４参照）よりも受網側に位置している。また、送り部材９１は、受網２７の扱胴周方向での一端側から他端側に亘っている。 The feed member 91 will be described in detail.
The feed member 91 protrudes further toward the handle cylinder side than the vertical beam 85 and the horizontal beam 86 of the receiving net 27 and receives more than the rotation trajectory T (see FIGS. 3 and 4) at the tip of the handle 55 of the handle cylinder 21. Located on the net side. The feed member 91 extends from one end side to the other end side in the circumferential direction of the barrel of the receiving net 27.

The feed member 91 is made of a square bar material so that the cross-sectional shape is rectangular.

図１９に示すように、受網２７は、４つの分割受網２７Ａを扱胴周方向に沿った縦接合面Ｒ１と、扱胴軸芯Ｐ２に平行又はほぼ平行に位置し、かつ縦接合面Ｒ１に交差した横接合面Ｒ２とで分離可能に接合させることによって構成してある。縦接合面Ｒ１は、端受網フレーム８８を扱胴軸芯Ｐ２に沿う方向に分割した分割フレーム、及び中受網フレーム８７を扱胴軸芯Ｐ２に沿う方向に分割した分割フレームそれぞれの接合面などによって形成してある。横接合面Ｒ２は、中受網フレーム８７を扱胴周方向に分割した分割フレームの接合面によって形成してある。扱胴周方向に並ぶ一対の分割受網２７Ａは、一方の分割受網２７Ａが備える中受網フレーム８７の分割フレームに設けた連結ピン８７ａ（図３，４参照）が他方の分割受網２７Ａが備える中受網フレーム８７の分割フレームに設けたピン孔に入り込むことによって、所定の連結状態になるように構成してある。   As shown in FIG. 19, the receiving net 27 is positioned in parallel or substantially parallel to the longitudinal joint surface R <b> 1 along the circumferential direction of the handling cylinder and the longitudinal axis P <b> 2 of the four divisional receiving nets 27 </ b> A. It is configured by being separably joined to the lateral joining surface R2 intersecting with R1. The longitudinal joint surface R1 is a joint surface of each of the divided frames obtained by dividing the end receiving frame 88 in the direction along the handle cylinder axis P2 and the divided frames obtained by dividing the intermediate mesh frame 87 in the direction along the handle cylinder axis P2. It is formed by. The lateral joint surface R2 is formed by a joint surface of a divided frame obtained by dividing the intermediate mesh frame 87 in the circumferential direction of the cylinder. In the pair of divided receiving nets 27A arranged in the circumferential direction of the barrel, the connecting pin 87a (see FIGS. 3 and 4) provided on the divided frame of the intermediate receiving net frame 87 provided in one divided receiving net 27A is the other divided receiving net 27A. Is configured so as to be in a predetermined connected state by entering into a pin hole provided in a divided frame of the intermediate receiving net frame 87 provided in.

従って、受網２７は、縦接合面Ｒ１を縦分割面として扱胴軸芯Ｐ２に沿う方向に二つの分割受網に分割し、横接合面Ｒ２を横分割面として扱胴周方向に二つの分割受網に分割することにより、四つの分割受網２７Ａに分割できる。   Therefore, the receiving net 27 is divided into two divided receiving nets in the direction along the cylinder axis P2 with the vertical joining surface R1 as the vertical dividing surface, and two in the circumferential direction of the handling cylinder with the horizontal joining surface R2 as the horizontal dividing surface. By dividing into divided receiving networks, it can be divided into four divided receiving networks 27A.

四つの分割受網２７Ａそれぞれの配置を入れ替えても、四つの分割受網２７Ａが所定どおりの受網２７を形成する状態に、各分割受網２７Ａを構成してある。
ただし、四つの分割受網２７Ａそれぞれの配置を入れ替えるに当たり、左右の配置を入れ替えずに前後の配置だけを入れ替える場合、分割受網２７Ａの左右向き及び前後向きを変更せずにそのままにする。左右の配置を入れ替える場合、分割受網２７Ａの左右向き及び前後向きを変更する。 Even if the arrangement of each of the four divided receiving networks 27A is changed, each divided receiving network 27A is configured such that the four divided receiving networks 27A form a predetermined receiving network 27.
However, when the arrangement of the four divided receiving networks 27A is changed, when only the front and rear arrangements are changed without changing the left and right arrangements, the left and right directions and the front and rear directions of the divided receiving networks 27A are not changed. When the left and right arrangements are switched, the left and right direction and the front and rear direction of the divided receiving network 27A are changed.

図２０は、分割受網２７Ａを示す平面図である。図１９，２０に示すように、送り部材９１は、四つの分割受網２７Ａに各別に支持された分割送り部材９１Ａを備えている。
従って、受網２７に備えてある送り部材９１は、受網２７を四つの分割受網２７Ａに分割することにより、扱胴軸芯Ｐ２の方向に二つの分割送り部材９１Ａに分割でき、かつ、扱胴周方向に二つの分割送り部材９１Ａに分割できる。すなわち、送り部材９１は、四つの分割送り部材９１Ａに分割できる。そして、四つの分割送り部材９１Ａのうち、受網２７の右前側の領域に位置する分割受網２７Ａに支持された分割送り部材９１Ａ、及び、受網２７の左後側の領域に位置する分割受網２７Ａに支持された分割送り部材９１Ａは、受網２７の扱胴周方向での一端と中間部とに亘っている。四つの分割送り部材９１Ａのうち、受網２７の左前側の領域に位置する分割受網２７Ａに支持された分割送り部材９１Ａと、受網２７の右後側の領域に位置する分割受網２７Ａに支持された分割送り部材９１Ａとが互いに連なり、互いに連なった二つの分割送り部材９１Ａは、受網２７の扱胴周方向での一端から他端に亘って位置する。 FIG. 20 is a plan view showing the divided receiving network 27A. As shown in FIGS. 19 and 20, the feeding member 91 includes divided feeding members 91 </ b> A that are individually supported by four divided receiving nets 27 </ b> A.
Therefore, the feeding member 91 provided in the receiving net 27 can be divided into two divided feeding members 91A in the direction of the barrel axis P2 by dividing the receiving net 27 into four divided receiving nets 27A, and It can be divided into two divided feeding members 91A in the circumferential direction of the barrel. That is, the feeding member 91 can be divided into four divided feeding members 91A. Of the four divided feeding members 91A, the divided feeding member 91A supported by the divided receiving net 27A located in the area on the right front side of the receiving net 27 and the division located in the left rear side area of the receiving net 27. The divided feeding member 91A supported by the receiving net 27A extends over one end and an intermediate portion of the receiving net 27 in the circumferential direction of the cylinder. Of the four divided feeding members 91A, the divided feeding member 91A supported by the divided receiving net 27A located in the left front area of the receiving net 27, and the divided receiving net 27A located in the right rear area of the receiving net 27 The divided feed members 91A supported by the two are connected to each other, and the two divided feed members 91A connected to each other are positioned from one end to the other end of the receiving net 27 in the circumferential direction of the cylinder.

四つの分割受網２７Ａそれぞれの配置を入れ替えて、受網２７の左前側の領域及び右後側の領域に位置する二つの分割受網２７Ａが入れ替わっても、受網２７の左前側の領域及び右後側の領域に位置した新たな二つの分割受網２７Ａに支持される分割送り部材９１Ａが互いに連なり、この二つの分割送り部材９１Ａは、受網２７の扱胴周方向での一端から他端に亘って位置する。   Even if the arrangement of the four divided receiving networks 27A is changed so that the two divided receiving networks 27A located in the left front area and the right rear area of the receiving network 27 are switched, the left front area of the receiving network 27 and Split feed members 91A supported by two new split receiving nets 27A located in the right rear region are connected to each other, and the two split feed members 91A are connected to each other from one end of the receiving net 27 in the circumferential direction of the cylinder. Located across the edge.

従って、受網２７の右前側及び左前側の領域に位置する分割受網２７Ａに支持される分割送り部材９１Ａに脱穀処理物との接触による磨滅が発生しやすいが、このように分割送り部材９１Ａに磨滅が発生した際、磨滅した分割送り部材９１Ａを支持する分割受網２７Ａだけを交換することにより、磨滅した分割送り部材９１Ａを新たな分割送り部材９１Ａに交換することができる。また、磨滅した分割送り部材９１Ａを支持する分割受網２７Ａと、この分割受網２７Ａと異なる箇所に配置してある分割受網２７Ａとを入れ替えることにより、磨滅した分割送り部材９１Ａを別の分割送り部材９１Ａと交換することができる。   Accordingly, the divided feed member 91A supported by the divided receiving net 27A located in the right front side and the left front side regions of the receiving net 27 is likely to be worn out by contact with the threshing processed material. When wear occurs, the worn divided feed member 91A can be replaced with a new divided feed member 91A by replacing only the divided receiving net 27A that supports the worn divided feed member 91A. Further, by replacing the divided receiving net 27A that supports the worn divided feeding member 91A and the divided receiving net 27A that is arranged at a location different from the divided receiving net 27A, the worn divided feeding member 91A is divided into different parts. It can be exchanged for the feed member 91A.
