Description

本発明は、コンバイン等に搭載される脱穀装置に係り、詳しくは、前後方向に揺動可能に支持され、脱穀処理された処理物を選別する揺動選別体を備えた脱穀装置に関する。   The present invention relates to a threshing apparatus mounted on a combine or the like, and more particularly, to a threshing apparatus including a swinging sorter that is supported so as to be swingable in the front-rear direction and that selects a processed product that has been threshed.

従来、コンバイン等に搭載される脱穀装置において、扱胴を収納する扱室の下方に、前後方向に揺動可能に支持された揺動選別体を有する選別室を備えたものがある。該揺動選別体は、扱胴によって脱穀された穀粒及び藁屑等の処理物を比重選別しつつ後方側へ流動させるフィードパンと、該フィードパンの後端に達した処理物を篩選別するチャフシーブとを有して構成されている。   2. Description of the Related Art Conventionally, some threshing devices mounted on a combiner or the like include a sorting chamber having a swinging sorter supported so as to be swingable in the front-rear direction below a handling chamber that houses a handling barrel. The rocking sorter sieve-sorts a feed pan that allows the processed product such as grain and sawdust, which has been threshed by the handling cylinder, to flow backward while being subjected to specific gravity selection, and the processed product that has reached the rear end of the feed pan. And a chaff sheave.

この種の脱穀装置において、揺動選別体の選別作業にて選別処理された二番物を、穀物の種類や状態に応じて再度扱室又は選別室に戻して再処理を行なう脱穀装置が知られている(特許文献1参照)。また、フィードパン上の処理物を分散し、均平にする拡散部材を備え、処理物の選別処理能力の向上を図ったものが知られている(特許文献2,3参照)。   In this type of threshing device, there is known a threshing device that reprocesses the second product that has been subjected to the sorting process by the sorting operation of the rocking sorter and returns it to the handling room or the sorting room according to the type and state of the grain. (See Patent Document 1). In addition, there is known a dispersion member that disperses and leveles the processed material on the feed pan and improves the processing capability of the processed material (see Patent Documents 2 and 3).

特許第3159173号公報Japanese Patent No. 3159173 特開平7−274685号公報Japanese Patent Laid-Open No. 7-274685 特開2005−304427号公報JP 2005-304427 A

しかしながら、上記特許文献1記載の脱穀装置は、二番物を選別室に直接還元する場合において、扱室で脱穀されて受網から漏下した処理物に加えて、選別室に塊となって還元された二番物が合流し、揺動選別装置上で処理物が偏在することで選別処理が間に合わずに、籾が機外へ飛散するという虞がある。   However, when the threshing apparatus described in Patent Document 1 directly reduces the second product to the sorting room, in addition to the processed product threshed in the handling room and leaked from the receiving net, it becomes a lump in the sorting room. There is a possibility that the second product that has been reduced merges, and the processed materials are unevenly distributed on the swing sorting device, so that the sorting processing is not in time, and soot is scattered outside the apparatus.

また、特許文献2及び3記載の脱穀装置は、二番物を選別室のフィードパン上に還元するものであって、例えば処理物の量が多い時に脱穀しきれなかった二番物を扱室に還元し再度脱穀することができず、穀稈の籾が脱穀されないままに機外へ飛散する虞がある。   In addition, the threshing devices described in Patent Documents 2 and 3 reduce the second product onto the feed pan of the sorting room, and for example, handle the second product that could not be threshed when the amount of processed material is large. It cannot be reduced to threshing again, and there is a risk that the cocoon cake will be scattered outside the machine without being threshed.

そこで、本発明は、穀物の種類等によって二番物の放出先を扱室と選別室とに切替え可能に構成するとともに、これら二番物の放出先に応じて処理物を効果的に分散させて、もって材料適応性及び選別処理能力を向上した脱穀装置を提供することを目的とする。   Therefore, the present invention is configured such that the second discharge destination can be switched between the handling chamber and the sorting chamber depending on the type of grain and the like, and the processed material is effectively dispersed according to the second discharge destination. An object of the present invention is to provide a threshing apparatus with improved material adaptability and sorting capacity.

本発明は、扱胴(20)を収納し、穀稈の脱穀処理を行なう扱室(19)と、該扱室(19)で脱穀処理された処理物を後方移送しつつ選別する揺動選別体(22)を有する選別室(9)と、を備え、前記選別室(9)で選別された二番物を前記扱室(19)と前記選別室(9)とに択一的に放出する脱穀装置(7)において、
前記選別室(9)の一側方に、前記二番物を前記揺動選別体(22)上に放出する選別室還元口(60)と、前記揺動選別体(22)上の処理物を分散させる寄せ板(49R)と、を配置し、
該寄せ板(49R)の高さを調節可能とした、
ことを特徴とする。
The present invention includes a handling chamber (19) that accommodates a handling cylinder (20) and performs threshing processing of cereals, and a swing sorting that sorts a processed product threshed in the handling chamber (19) while moving backward. A sorting chamber (9) having a body (22), and selectively discharging the second item sorted in the sorting chamber (9) into the handling chamber (19) and the sorting chamber (9). In the threshing device (7)
In one side of the sorting chamber (9), a sorting chamber reduction port (60) for discharging the second product onto the swinging sorter (22), and a processed product on the swinging sorter (22). A disposing plate (49R) for dispersing
The height of the gathering plate (49R) can be adjusted,
It is characterized by that.

例えば図11を参照して、前記寄せ板(49R)は、前記選別室還元口(60)と機体(3)の前後方向に少なくとも一部が重なるように配置されてなる。   For example, referring to FIG. 11, the abutment plate (49R) is arranged so that at least a part thereof overlaps in the front-rear direction of the sorting chamber return port (60) and the machine body (3).

例えば図11を参照して、前記寄せ板(49R)は、前記一側方に向って徐々に高く形成されてなる。   For example, referring to FIG. 11, the abutting plate (49R) is formed to be gradually higher toward the one side.

なお、上述カッコ内の符号は、図面と対照するためのものであるが、何ら本発明の構成を限定するものではない。   In addition, although the code | symbol in the said parenthesis is for contrast with drawing, it does not limit the structure of this invention at all.

請求項1に係る本発明は、選別室で選別された二番物を扱室と選別室とに択一的に放出すると共に、選別室還元口と同じ側に配置した寄せ板の高さを調節可能として、例えば大豆等の傷の付きやすい穀物の場合に、二番物を選別室還元口から揺動選別体上に放出するように設定する。すると、受網から漏下する処理物と放出された二番物とが合流して、揺動選別体上の寄せ板側の処理物が増加するので、上記寄せ板を高く設定し、該寄せ板側の処理物を揺動選別体の中央側へと寄せ、揺動選別体上の処理物を均平にすることで選別処理能力が向上するので、籾が機外飛散されて排出ロスが発生することを防止することができる。また、例えば稲・麦等の傷の付きにくい穀物や処理物の量が多い場合には、二番物を扱室に還元するように設定し、処理物は受網を介して揺動選別体上に漏下して、二番物を選別室還元口から放出する場合に比して処理物の偏在が少ないので、寄せ板を低く設定することで揺動選別体上の処理物の均平性が向上し、排出ロスの発生を防止することができる。   The present invention according to claim 1 selectively discharges the second item sorted in the sorting chamber into the handling chamber and the sorting chamber, and also sets the height of the gathering plate disposed on the same side as the sorting chamber return port. For example, in the case of grain that is easily scratched, such as soybean, the second product is set to be discharged from the sorting chamber reducing port onto the swinging sorter. Then, the processed material leaking from the receiving net and the discharged second material are joined, and the processed material on the side plate on the rocking sorter increases. By moving the processed material on the plate side toward the center of the rocking sorter and leveling the treated material on the rocking sorter, the sorting capacity is improved. Occurrence can be prevented. Also, for example, if there is a large amount of grain or processed material that is difficult to scratch, such as rice and wheat, it is set so that the second product is returned to the handling room, and the processed material is swung through the receiving net. Since the unevenness of the processed material is less than when the second product is discharged from the sorting chamber reduction port by leaking upward, the leveling of the processed material on the rocking sorter is reduced by setting the lowering plate. And the occurrence of discharge loss can be prevented.

このように、穀物の種類や状態等に応じて、二番物を扱室又は選別室に択一的に放出し、該放出先に適合するように寄せ板の高さを調節して揺動選別体上の処理物の均平性を向上し、材料適応性及び選別処理能力を向上することができる。   In this way, depending on the type and condition of the grain, the second item is alternatively discharged into the handling room or sorting room, and the height of the gathering plate is adjusted so as to match the discharge destination, and swings. It is possible to improve the flatness of the processed material on the sorting body, and to improve the material adaptability and the sorting processing capability.

請求項2に係る本発明は、寄せ板が選別室還元口と機体の前後方向に少なくとも一部が重なるように配置され、該選別室還元口から放出された二番物が寄せ板の前方側と後方側の双方に放出されるので、放出された二番物が全て寄せ板によって揺動選別体の中央側に寄ってしまって、該揺動選別体の中央側に集まりすぎることがなく、揺動選別体上の処理物が効率的に分散されて処理物の均平性を向上することができる。   The present invention according to claim 2 is arranged so that the sorter plate overlaps at least partly with the sorting chamber return port in the front-rear direction of the machine body, and the second object discharged from the sorter chamber return port is located on the front side of the sorter plate. And the second product that has been released is all moved closer to the center side of the swinging sorter by the gathering plate, and does not gather too much on the center side of the swinging sorter, The processed material on the swing sorter can be efficiently dispersed to improve the uniformity of the processed material.

請求項3に係る本発明は、寄せ板を選別室の一側方に向かって徐々に高く形成し、選別室の一側方側は処理物が寄せ板を乗越えにくく、後方移送されつつ中央側に寄せられ、かつ選別室の中央側は処理物が寄せ板を乗越えやすいので、二番物が多い場合に処理物の詰まりを防止すると共に揺動選別体上での処理物の均平性を向上することができる。   According to the third aspect of the present invention, the gathering plate is formed so as to be gradually higher toward one side of the sorting chamber, and the one side of the sorting chamber is difficult to get over the gathering plate. In the center of the sorting chamber, the processed material can easily get over the collecting plate, preventing clogging of the processed material when there are many second products, and ensuring the uniformity of the processed material on the rocking sorter. Can be improved.

At the same time, the processed material that tends to stay on the rocking sorter 22 especially near the left and right ends is dispersed toward the center. Among the four pairs of the gathering plates 49R, 49L, 50R, 50L, 51R, 51L, 52R, 52L, the gathering plates 51R, 51L, 52R, 52L located on the rear side are the left and right sides of the swing sorter 22 described above. In order to prevent the grains on the end from being discharged out of the machine, the grain is configured to extend to the outside of the above-mentioned close plates 49R, 49L, 50R, 50L located on the front side.

上記選別室9の側壁には、図11に示すように、上記選別室連通口45から落下した処理物が選別室9内に放出される選別室還元口60が形成されていると共に、該処理物を落下案内するガイド板59が固定されており、4対の寄せ板49R,49L、50R,50L、51R,51L、52R,52Lのうち、最も前方に配置され、上記選別室9の一側方である上記選別室連通口45側に位置する寄せ板49Rは、平面視において、上記選別室還元口60と機体3の前後方向に少なくとも一部が重なるように配置されている。これにより、選別室9に還元される二番物は、寄せ板49Rの前方側と後方側の双方に放出されるように構成されている。また、上記寄せ板49Rは、上記揺動選別体22に固定される略長方形状の固定板53と、該固定板53に重ね合わせられて、ボルト55,55によって上記固定板53に固定される可動板56と、から構成される。該可動板56は、長穴57,57を有し、上記ボルト55,55が貫通する長穴の位置を変更することで、上記寄せ板49Rの高さを調節可能に構成されていると共に、傾斜部56aを有し、上記選別室9の一側方である上記選別室連通口45側に向って徐々に高くなるように形成されている。   As shown in FIG. 11, the side wall of the sorting chamber 9 is formed with a sorting chamber reduction port 60 through which the processed material dropped from the sorting chamber communication port 45 is discharged into the sorting chamber 9. A guide plate 59 that guides the object to fall is fixed, and is arranged at the foremost side of the four pairs of gathering plates 49R, 49L, 50R, 50L, 51R, 51L, 52R, 52L, and one side of the sorting chamber 9 The approach plate 49R located on the side of the sorting chamber communication port 45, which is the other side, is arranged so that at least a part thereof overlaps with the sorting chamber return port 60 in the front-rear direction of the machine body 3 in plan view. Thereby, the second item returned to the sorting chamber 9 is configured to be discharged to both the front side and the rear side of the approach plate 49R. Further, the gathering plate 49R is superposed on the substantially rectangular fixing plate 53 fixed to the swing sorting body 22 and the fixing plate 53, and is fixed to the fixing plate 53 by bolts 55, 55. And a movable plate 56. The movable plate 56 has long holes 57, 57, and is configured such that the height of the gathering plate 49R can be adjusted by changing the position of the long hole through which the bolts 55, 55 pass. It has an inclined portion 56 a and is formed so as to gradually increase toward the sorting chamber communication port 45 side that is one side of the sorting chamber 9.

本実施の形態は、以上のような構成からなるので、作業者は、コンバイン1の運転操作部6において運転操作を行い、前処理部5において穀稈の刈取り・搬送作業を行なうと共に、脱穀装置7の扱室19で脱穀作業、選別室9で選別作業を行なう。該扱室19で脱穀されて、受網21から揺動選別体22に落下した処理物は、唐箕ファン23及び送風ファン24によって風選別されつつ、揺動選別体22上で篩選別されて、一番ラセン32に回収された一番物は、揚穀装置37によってグレンタンク10に貯留される。二番ラセン33に回収された二番物は、還元装置40によって還元室39に還元された後、還元横ラセン41によって搬送されて扱室19又は選別室9に択一的に放出される。   Since the present embodiment is configured as described above, the operator performs a driving operation in the driving operation unit 6 of the combine 1, and performs a grain reaping and transporting operation in the preprocessing unit 5, and a threshing device. 7 in the handling room 19 and sorting in the sorting room 9. The processed product that has been threshed in the handling chamber 19 and dropped from the receiving net 21 onto the swinging sorter 22 is subjected to screen sorting on the swinging sorter 22 while being wind-sorted by the tang fan 23 and the blower fan 24. The first thing collected in the first spiral 32 is stored in the grain tank 10 by the cerealing device 37. The second product collected in the second helix 33 is reduced to the reduction chamber 39 by the reduction device 40, and then conveyed by the reducing horizontal helix 41 to be selectively discharged to the handling chamber 19 or the sorting chamber 9.

この際、刈取った穀物が例えば稲・麦等の傷の付きにくい穀物や処理物の量が多い場合、枝梗を処理して籾の品質を向上したい場合には、二番物を扱室19に還元して再度脱穀を行なう。そのために、作業者は、選別室連通口45を閉塞するように連通口カバー46を還元室39に取り付けて、二番物が扱室還元口42まで搬送されるように構成する(図5参照)。該扱室還元口42まで搬送された二番物は、図9に示すように、跳出板43によって扱室19内に跳ね出されて、再度扱室19において脱穀される。   In this case, if the harvested grain has a large amount of scratched grain such as rice or wheat, or the processed material, if you want to improve the quality of the straw by treating the branch, Reduce to 19 and thresh again. For this purpose, the operator attaches the communication port cover 46 to the reduction chamber 39 so as to close the sorting chamber communication port 45 so that the second item is conveyed to the handling chamber reduction port 42 (see FIG. 5). ). As shown in FIG. 9, the second product conveyed to the handling chamber return port 42 is splashed into the handling chamber 19 by the jumping plate 43 and threshed again in the handling chamber 19.

このように二番物を扱室19に再度還元する場合には、図10に示すように、寄せ板49Rを、可動板56が固定板53の上方に突出しないように重ね合わせて、すなわち寄せ板49Rを低く設定して、反対側の寄せ板49Lと略同じ高さに調整する。受網21の円周方向において、該受網21から均等に処理物が落下した場合、揺動選別体22の両側方の処理物量が多くなるが、寄せ板49R側と寄せ板49L側の処理物量には差がないので、これら寄せ板49Rと寄せ板49Lの高さを略同じにすることで、揺動選別体上の処理物の均平性を向上し、排出ロスの発生を防止することができる。   In this way, when the second item is returned again to the handling chamber 19, as shown in FIG. 10, the approach plate 49 </ b> R is overlapped so that the movable plate 56 does not protrude above the fixed plate 53. The plate 49R is set low and adjusted to substantially the same height as the counter plate 49L on the opposite side. In the circumferential direction of the receiving net 21, if the processed material falls evenly from the receiving net 21, the amount of processed material on both sides of the swing sorter 22 increases, but the processing on the side plate 49 </ b> R side and the side plate 49 </ b> L side is increased. Since there is no difference in the amount of material, by making the height of the gathering plate 49R and the gathering plate 49L substantially the same, it is possible to improve the flatness of the processed material on the swinging sorter and prevent the occurrence of discharge loss. be able to.

一方、例えば大豆等の傷の付きやすい穀物の場合には、二番物を選別室9に直接放出する。そのために、作業者は選別室連通口45を開放するように連通口カバー46を還元室39から取り外して、該選別室連通口45から二番物が落下するように構成する(図6参照)。選別室連通口45から落下した二番物は、選別室還元口60から選別室9に放出され、ガイド板59に落下案内される。該ガイド板59に落下案内された二番物は、揺動選別体22上における寄せ板49Rの前方側と後方側の双方に落下し、該寄せ板49Rの前方側に放出された二番物は、該寄せ板49Rによって揺動選別体22の左右方向中央側に寄せられ、該寄せ板49Rの後方側に放出された二番物は、該寄せ板49Rによって揺動選別体22の左右方向中央側に寄せられることなく後方移送される。これにより、放出された二番物が全て寄せ板49Rによって揺動選別体22の中央側に寄ってしまって、揺動選別体22の左右方向中央部に集まりすぎることがなく、揺動選別体22上の処理物が効率的に分散されて処理物の均平性を向上することができる。   On the other hand, in the case of easily damaged grains such as soybeans, the second product is directly discharged into the sorting chamber 9. For this purpose, the operator removes the communication port cover 46 from the reduction chamber 39 so as to open the sorting chamber communication port 45, and the second product falls from the sorting chamber communication port 45 (see FIG. 6). . The second item dropped from the sorting chamber communication port 45 is discharged from the sorting chamber reducing port 60 to the sorting chamber 9 and is guided to drop by the guide plate 59. The second object dropped and guided to the guide plate 59 falls on both the front side and the rear side of the approach plate 49R on the swing sorter 22, and the second object released to the front side of the approach plate 49R. Is moved toward the center of the rocking sorter 22 in the left-right direction by the gathering plate 49R, and the second object discharged to the rear side of the gathering plate 49R is moved in the left-right direction of the rocking sorter 22 by the gathering plate 49R. It is transported backward without being brought to the center side. As a result, all the released second objects are not moved to the central side of the swinging sorter 22 by the gathering plate 49R, and do not collect too much in the central portion in the left-right direction of the swinging sorter 22, and the swing sorter The processed material on 22 can be efficiently dispersed to improve the flatness of the processed material.

このように二番物を選別室9に放出する場合には、図11に示すように、サイドカバー36を開けて、寄せ板49Rを可動板56が固定板53の上方に突出するように固定し、すなわち寄せ板49Rを高く設定して、反対側の寄せ板49Lよりも高く調節する。揺動選別体22上において、受網21から漏下する処理物と選別室還元口60から放出された二番物とが合流して、寄せ板49R側の処理物量は寄せ板49L側の処理物量よりも多くなるので、寄せ板49Rを高く設定することで、該寄せ板49R側の処理物を寄せ板49L側の処理物より多く揺動選別体22の中央側に寄せて、揺動選別体22上の処理物の均平性を向上して、選別処理能力を向上することができる。   When the second product is discharged into the sorting chamber 9 in this way, as shown in FIG. 11, the side cover 36 is opened and the moving plate 49R is fixed so that the movable plate 56 protrudes above the fixed plate 53. That is, the adjusting plate 49R is set higher and adjusted to be higher than the adjusting plate 49L on the opposite side. On the swinging sorter 22, the processed material leaking from the receiving net 21 and the second material discharged from the sorting chamber reducing port 60 are merged, and the amount of processed material on the side plate 49R side is equal to that on the side plate 49L side. Since the amount is larger than the amount of material, by setting the gathering plate 49R higher, the processed material on the working plate 49R side is brought closer to the center side of the rocking sorter 22 than the processed product on the working plate 49L side, and the shaking sorting is performed. The uniformity of the processed material on the body 22 can be improved, and the sorting processing ability can be improved.

以上のように、穀物の種類や状態等に応じて、二番物を扱室19又は選別室9に択一的に放出し、該放出先に適合するように寄せ板49Rの高さを調節して揺動選別体22上の処理物の均平性を向上し、材料適応性及び選別処理能力を向上することができる。   As described above, the second product is selectively discharged into the handling chamber 19 or the sorting chamber 9 according to the type and state of the grain, and the height of the closing plate 49R is adjusted so as to match the discharge destination. As a result, the levelness of the processed material on the rocking sorter 22 can be improved, and the material adaptability and the sorting capacity can be improved.

また、寄せ板49Rを高く設定した場合には、寄せ板49Rは、可動板56に形成された傾斜部56aによって、選別室連通口45並びに選別室還元口60側に向って徐々に高くなるように形成されているので、揺動選別体22中央側では寄せ板49Rと受網21との隙間が広くなり、詰まりを防止することができると共に、処理物量の多い選別室還元口60側でより多くの処理物を中央側に寄せることができ、処理物の均平性を向上することができる。   Further, when the close plate 49R is set high, the close plate 49R is gradually increased toward the sorting chamber communication port 45 and the sorting chamber return port 60 by the inclined portion 56a formed on the movable plate 56. Therefore, the gap between the gathering plate 49R and the receiving net 21 is widened at the center side of the oscillating sorter 22 so that clogging can be prevented, and at the sorter chamber reducing port 60 side where the amount of processed material is large. Many processed products can be brought to the center side, and the uniformity of the processed products can be improved.

なお、寄せ板49Rは、背を低く設定する際に、可動板56を固定板53に重ね合わせずに取り外してもよく、また固定板及び可動板の二枚から構成せずに、一枚の板からなる異なる高さの板を複数枚用意して、これらを取り外しして構成してもよい。   Note that when the back plate 49R is set low, the movable plate 56 may be removed without being superimposed on the fixed plate 53, and it is not composed of the fixed plate and the movable plate. A plurality of plates having different heights made of plates may be prepared and removed.
