JP 2001-161154 A

ところが、上記した脱穀装置では、受網体の一側半部に張設した鉄板により受網体の網目を潰しているために、脱穀処理物の漏下性能が低減し、後続作業である処理物の選別作業性能に悪影響を与えている。   However, in the above-described threshing apparatus, the netting performance of the threshing product is reduced because the mesh of the receiving net body is crushed by the steel plate stretched on one side half of the receiving net body, and the subsequent work This has an adverse effect on the sorting work performance.

そこで、本発明では、外周面に多数の扱歯を突設した扱胴と、同扱胴の直下方位置において扱胴の周面に沿わせて張設した受網体とを具備し、同受網体と扱胴の外周面との間に穀稈を挿入すると共に、同穀稈を扱胴の軸線方向に穀稈搬入側から穀稈搬出側へ向けて移送させながら、軸線廻りに回転する扱胴の扱歯により脱穀し、脱穀・処理した脱穀処理物を受網体の網目を通して漏下させるようにした脱穀装置において、受網体は、穀稈の穂先部側を受ける一側半部を形成するクリンプ網と、穀稈の株元部側を受ける他側半部を形成する鋼板製網とを具備し、クリンプ網と鋼板製網の境界線の位置は、穀稈搬入側から穀稈搬出側に向けて移送される穀稈の穂先部を、漸次、クリンプ網側から鋼板製網側に移送させて、穀稈搬出側に至っては穀稈の穂先部の略全部が鋼板製網上に位置するように設定したことを特徴とする脱穀装置を提供するものである。 Therefore, in the present invention, a handling cylinder having a large number of teeth handling teeth projecting on the outer circumferential surface, and a receiving net body stretched along the circumferential surface of the handling cylinder at a position directly below the handling cylinder, Rotating around the axis while inserting cereals between the receiving net and the outer peripheral surface of the handling cylinder and moving the cereals in the axial direction of the handling cylinder from the cereal carry-in side to the cereal carry-out side In the threshing device, the threshing device is configured such that the processed threshing product is threshed by the tooth handling of the handling barrel and leaked through the mesh of the receiving mesh body. A crimp net that forms a portion and a steel plate net that forms the other half of the cereal stock side, and the position of the boundary line between the crimp net and the steel plate net is from the cereal carry-in side Gradually, the tip of the cereals transferred toward the cereal carry-out side is gradually transferred from the crimp net side to the steel plate net side, and the grain cereal is transferred to the cereal carry-out side. Substantially all of the tip portion there is provided a threshing device being characterized in that set so as to be positioned on steel network.

また、本発明は、クリンプ網と鋼板製網は着脱自在に連結したことにも特徴を有する。 The present invention is also characterized in that the crimp net and the steel plate net are detachably connected .

(1)請求項1記載の本発明では、外周面に多数の扱歯を突設した扱胴と、同扱胴の直下方位置において扱胴の周面に沿わせて張設した受網体とを具備し、同受網体と扱胴の外周面との間に穀稈を挿入すると共に、同穀稈を扱胴の軸線方向に移送させながら軸線廻りに回転する扱胴の扱歯により脱穀し、脱穀・処理した脱穀処理物を受網体の網目を通して漏下させるようにした脱穀装置において、受網体は、穀稈の穂先部側を受ける一側半部を形成するクリンプ網と、穀稈の株元部側を受ける他側半部を形成する鋼板製網とを具備している。   (1) In the present invention described in claim 1, a handling cylinder having a large number of teeth on the outer circumferential surface thereof, and a receiving net member stretched along the circumferential surface of the handling cylinder at a position directly below the handling cylinder. And inserting a grain basket between the receiving net and the outer peripheral surface of the handle cylinder, and moving the grain basket in the axial direction of the handle cylinder while rotating the axis of the handle cylinder In the threshing apparatus in which the threshing product that has been threshed and threshed and processed is allowed to leak through the mesh of the receiving net body, the receiving net body has a crimp net that forms one half that receives the tip side of the cereal , And a steel plate net forming the other half of the cereal stock side.

このようにして、穀稈の株元部側を鋼板製網により受けるようにしているため、穀稈の株元部が鋼板製網上を円滑に移送されるようにすることができると共に、同鋼板製網を通しても脱穀処理物を漏下させることができて、脱穀処理物の漏下性能を良好に確保することができる。   In this way, the cereal base part of the cereal is received by the steel sheet net, so that the cereal base part of the cereal can be smoothly transferred on the steel sheet net. The threshing processed product can be leaked through the steel plate net, and the leakage performance of the threshing processed product can be ensured satisfactorily.

その結果、後続作業である処理物の選別作業性能も良好に確保することができる。   As a result, it is possible to satisfactorily ensure the sorting work performance of the processed material as the subsequent work.

しかも、クリンプ網と鋼板製網の境界線の位置は、穀稈搬入側から穀稈搬出側に向けて移送される穀稈の穂先部を、漸次、クリンプ網側から鋼板製網側に移送させて、穀稈搬出側に至っては穀稈の穂先部の略全部が鋼板製網上に位置するように設定している。 In addition , the position of the boundary between the crimp net and the steel plate net is such that the tip of the cereals transferred from the cereal carry-in side to the cereal carry-out side is gradually transferred from the crimp net side to the steel plate net side. Thus, it is set so that almost all of the tip part of the corn straw is located on the steel plate net when it reaches the grain pallet delivery side.

このようにして、穀稈搬入側から穀稈搬出側に至るまでは穀稈の穂先部をクリンプ網上にて移送させるようにしているため、同クリンプ網と扱胴との協働により穂先部の脱穀を確実に行って、脱穀効率を向上させることができる。   In this way, since the tip part of the cereal is transferred on the crimp net from the cereal carry-in side to the cereal carry-out side, the tip part is cooperated with the crimp net and the handling cylinder. The threshing efficiency can be improved and the threshing efficiency can be improved.

そして、穀稈搬出側に至っては、穂先部の略全部が鋼板製網上に位置するようにしているため、同穀稈搬出側から穀稈を円滑かつ確実に搬出することができる。   And since it reaches the cereal carry-out side, almost all of the tip part is located on the steel plate net, so the cereal can be carried out smoothly and reliably from the cereal carry-out side.

この際、穀稈の株元部は、穀稈搬入側から穀稈搬出側まで鋼板製網上にて円滑に移送されるため、穀稈の移送作業効率を向上させることができる。   At this time, the cereal stock portion is smoothly transferred on the steel plate net from the cereal carry-in side to the cereal carry-out side, so that the transfer work efficiency of the cereal can be improved.

(2)請求項記載の本発明では、クリンプ網と鋼板製網は着脱自在に連結している。 (2) In the present invention described in claim 2 , the crimp net and the steel plate net are detachably connected.

このようにして、クリンプ網と鋼板製網を着脱自在に連結しているため、例えば、クリンプ網が経時的に摩耗して、網としての機能を果たさなくなった場合には、同クリンプ網だけを取り替えることができる。その結果、受網体全体を交換する必要性がなくなり、同受網体の交換コストの低減化を図ることができる。   In this way, since the crimp net and the steel sheet net are detachably connected, for example, when the crimp net wears out over time and does not function as a net, only the crimp net is used. Can be replaced. As a result, it is not necessary to replace the entire receiving network body, and the replacement cost of the receiving network body can be reduced.

ここで、本実施の形態では、図3に示すように、脱穀部(4)は、外周面に多数の扱歯(6a)を突設した扱胴(6)と、同扱胴(6)の直下方位置において扱胴(6)の外周面に沿わせて湾曲状に張設した受網体(24)とを具備し、同受網体(24)と扱胴(6)の外周面との間に穀稈(K)(図4参照)を挿入すると共に、同穀稈(K)を扱胴(6)の軸線方向(P)に移送させながら軸線廻りに回転する扱胴(6)の扱歯(6a)により脱穀し、脱穀・処理した脱穀処理物を受網体(24)の網目を通して漏下させるようにしている。   Here, in this Embodiment, as shown in FIG. 3, a threshing part (4) is a treatment cylinder (6) which protruded many teeth (6a) on the outer peripheral surface, and the treatment cylinder (6). A receiving net body (24) extending in a curved shape along the outer peripheral surface of the handling cylinder (6) at a position directly below the outer circumference of the receiving net body (24) and the outer cylinder (6) A cedar (K) (see FIG. 4) is inserted between the halves and the barrel (6) rotating around the axis while transferring the cereal culm (K) in the axial direction (P) of the barrel (6). ), The threshing processed product that has been threshed and processed is leaked through the mesh of the receiving net body (24).

上記のような構成において、本発明の要旨は、図4に示すように、受網体(24)が、穀稈(K)の穂先部(Kh)側を受ける一側半部(本実施の形態では右側半部)を形成するクリンプ網(40)と、穀稈(K)の株元部(Km)側を受ける他側半部(本実施の形態では左側半部)を形成する鋼板製網(41)とを具備していることにある。   In the configuration as described above, the gist of the present invention is that, as shown in FIG. 4, the receiving net body (24) receives one side half (this embodiment) that receives the tip (Kh) side of the cereal (K). Steel plate forming a crimp net (40) that forms the right half in the form and the other half (left half in the present embodiment) that receives the side of the stock (Km) of the cereal (K) And a net (41).

すなわち、受網体(24)は、網体支持枠(42)にクリンプ網(40)と鋼板製網(41)とを張設・支持しており、同網体支持枠(42)は、クリンプ網(40)を補強リブ片(43)を介して着脱自在に張設・支持する四角形枠状のクリンプ網支持枠形成片(44)と、鋼板製網(41)を補強リブ片(45)を介して着脱自在に張設・支持する四角形枠状の鋼板製網支持枠形成片(46)とから形成している。   That is, the receiving net body (24) stretches and supports the crimp net (40) and the steel plate net (41) on the net body support frame (42), and the net support frame (42) A quadrilateral frame-shaped crimp net support frame forming piece (44) for detachably stretching and supporting the crimp net (40) via the reinforcing rib piece (43), and a steel plate net (41) including the reinforcing rib piece (45). ) Through a rectangular frame-shaped steel plate net support frame forming piece (46) that is detachably stretched and supported via a).

そして、クリンプ網(40)は、素線を波形に加工した縦線(40a)と横線(40b)とを一定間隔で配列した金網であり、クリンプ網(40)の表面に凹凸面を形成して、扱胴(6)に突設した扱歯(6a)と協働して穀稈(K)の穂先部(Kh)をもみほぐして脱穀するようにしている。   The crimp net (40) is a metal net in which vertical lines (40a) and horizontal lines (40b) obtained by processing a wire into a waveform are arranged at regular intervals, and an uneven surface is formed on the surface of the crimp net (40). Thus, in cooperation with the tooth handling (6a) projecting from the handling cylinder (6), the tip (Kh) of the cereal basket (K) is loosened and threshed.

また、鋼板製網(41)は、板厚が4.5mmから3.2mmの鋼板に、プレス加工による打ち抜きによって、処理物漏下孔としての網目(41a)を多数穿設しているものであり、網目(41a)は四角形状に形成して前後左右方向にそれぞれ整然と配置している。   The steel plate net (41) is a steel plate having a thickness of 4.5 mm to 3.2 mm, in which a large number of meshes (41a) as processed material leakage holes are punched by stamping. Yes, the mesh (41a) is formed in a quadrangular shape and arranged in an orderly manner in the front-rear and left-right directions.

このようにして、穀稈(K)の株元部(Km)側を鋼板製網(41)により受けるようにしているため、穀稈(K)の株元部株元部(Km)が鋼板製網(41)上を円滑に移送されるようにすることができると共に、同鋼板製網(41)を通しても脱穀処理物を漏下させることができて、脱穀処理物の漏下性能を良好に確保することができる。   In this way, since the stock base part (Km) side of the grain straw (K) is received by the steel plate net (41), the stock base part stock base part (Km) of the grain straw (K) is a steel plate. While being able to be smoothly transferred on the net (41), the threshing product can be leaked also through the steel plate net (41), and the leakage performance of the threshing product is good. Can be secured.

その結果、後続作業である処理物の選別作業性能も良好に確保することができる。   As a result, it is possible to satisfactorily ensure the sorting work performance of the processed material as the subsequent work.

また、クリンプ網(40)と鋼板製網(41)の境界線の位置、すなわち、クリンプ網支持枠形成片(44)と鋼板製網支持枠形成片(46)との接合位置(B)は、穀稈搬入側(a)から穀稈搬出側(b)に向けてフィードチェン(5)により移送される穀稈(K)の穂先部(Kh)を、漸次、クリンプ網(40)側から鋼板製網(41)側に移送させて、穀稈搬出側(b)に至っては穀稈(K)の穂先部(Kh)の略全部が鋼板製網(41)上に位置するように設定している。   Further, the position of the boundary line between the crimp net (40) and the steel plate net (41), that is, the joining position (B) between the crimp net support frame forming piece (44) and the steel plate net supporting frame forming piece (46) is The tip (Kh) of the cereal (K) transferred by the feed chain (5) from the cereal carry-in side (a) to the cereal carry-out side (b) is gradually moved from the crimp net (40) side. It is transferred to the steel plate net (41) side, and is set so that almost all of the tip part (Kh) of the cereal (K) is located on the steel plate net (41) when it reaches the cereal carry-out side (b). is doing.

すなわち、標準扱ぎにおける穂先部(Kh)の先端の移送軌跡(Q0)も、深扱ぎにおける穂先部(Kh)の先端の移送軌跡(Q1)も、浅扱ぎにおける穂先部(Kh)の先端の移送軌跡(Q2)も、穀稈搬出側(b)においては、鋼板製網(41)上に位置して、穀稈(K)の穂先部(Kh)の略全部が鋼板製網(41)上に位置するようにしている。   That is, the transfer trajectory (Q0) at the tip of the tip (Kh) in standard handling and the transfer trajectory (Q1) at the tip of the tip (Kh) in deep handling are both of the tip (Kh) in shallow handling. The transfer trajectory (Q2) at the tip is also located on the steel plate net (41) on the cereal carry-out side (b), and almost all of the tip part (Kh) of the cereal (K) is made of the steel plate net ( 41) It is located above.

このようにして、穀稈搬入側(a)から穀稈搬出側(b)に至るまでは、穀稈(K)の穂先部(Kh)をクリンプ網(40)上にて移送させるようにしているため、同クリンプ網(40)と扱胴(6)の扱歯(6a)との協働により穂先部(Kh)の脱穀を確実に行って、脱穀効率を向上させることができる。   In this way, the tip (Kh) of the culm (K) is transferred on the crimp net (40) from the cereal carrying-in side (a) to the cereal carrying-out side (b). Therefore, the threshing efficiency can be improved by reliably threshing the tip part (Kh) by the cooperation of the crimp net (40) and the tooth handling (6a) of the handling cylinder (6).

そして、穀稈搬出側(b)に至っては、穂先部(Kh)の略全部が鋼板製網(41)上に位置するようにしているため、同穀稈搬出側(b)から穀稈(K)を円滑かつ確実に搬出することができる。   And since it is made for the whole grain tip part (Kh) to be located on a steel-plate net | network (41), it reaches from the grain grain delivery side (b), and grain grain ( K) can be carried out smoothly and reliably.

本発明の実施形態は上記のように構成しているものであり、本実施の形態によれば、次のような作用効果が得られる。   The embodiment of the present invention is configured as described above. According to the present embodiment, the following operational effects can be obtained.

すなわち、本実施の形態では、前部フィードパン(26)の後下方位置に段差をもたせて後部フィードパン(27)を配置して、段差の部分に選別風流入口(53)を形成しているため、前部フィードパン(26)から後部フィードパン(27)に移送・落下される選別物は、段差の部分の選別風流入口(53)から流入する送塵ファン(31)からの選別風により風選別される。   That is, in the present embodiment, the rear feed pan (27) is provided with a step at the rear lower position of the front feed pan (26), and the sorting wind inlet (53) is formed at the step portion. Therefore, the sorted material transferred / dropped from the front feed pan (26) to the rear feed pan (27) is subjected to the sorting wind from the dust feed fan (31) flowing in from the sorting wind inlet (53) in the stepped portion. Wind-sorted.

そのため、大量の選別物が前部フィードパン(26)上において扱胴(6)の回転方向(本実施の形態では正面視にて時計廻り)下手側、すなわち、穂先側に漏下した場合にも、同前部フィードパン(26)上に配置した前部選別物案内体(60)により大量の選別物は、扱胴(6)の回転方向下手側から回転方向上手側、すなわち、穂先側から株元側に案内されて、風選別された後に後部フィードパン(27)上に移送され、同後部フィードパン(27)上に移送された選別物は、後部選別物案内体(61)によりさらに穂先側から株元側に案内されて均一に分散される。   Therefore, when a large amount of selected material leaks on the front feed pan (26) to the lower side of the rotation direction of the handling cylinder (6) (clockwise in the present embodiment when viewed from the front), that is, to the tip side. In addition, a large amount of the sorted matter is moved from the lower side in the rotational direction of the handling cylinder (6) to the upper side in the rotational direction, that is, the tip side by the front sorted matter guide body (60) disposed on the front feed pan (26). To the stocker side, and after being sorted by wind, transferred to the rear feed pan (27) and transferred to the rear feed pan (27) by the rear selected item guide (61). Furthermore, it is guided from the tip side to the stock source side and uniformly dispersed.

この際、後部選別物案内体(61)は、平面視にて、前部選別物案内体(60)の仮想延長線(L)上に配置しているため、選別物の分散化を良好に確保することができる。   At this time, the rear selection object guide (61) is arranged on the virtual extension line (L) of the front selection object guide (60) in a plan view, so that the distribution of the selection is improved. Can be secured.

しかも、前・後部フィードパン(60,61)の上面に他側縁部から一側縁部に向けて下り傾斜状の前・後部案内作用面(64,66)を形成しているため、各前・後部案内作用面(64,66)を可及的に大きく形成することができて、大量の選別物でも確実に穂先側から株元側に移送・案内しながら均一に分散させることができる。   Moreover, since the front and rear guiding action surfaces (64, 66) having a downward slope are formed on the upper surface of the front / rear feed pan (60, 61) from the other side edge toward the one side edge, The front / rear guiding action surfaces (64, 66) can be formed as large as possible, and even a large amount of selected items can be uniformly dispersed while being transferred and guided from the tip side to the stock side. .

さらには、前部案内作用面(64)の傾斜案内幅(Wf)を後部案内作用面(66)の傾斜案内幅(Wr)よりも広幅に形成しているため、大量の選別物でも確実に前部案内作用面(64)で受けて、ある程度分散させた後に後部案内作用面(66)に引き継いで、同後部案内作用面によりさらに分散化することができる。   Furthermore, since the inclination guide width (Wf) of the front guide action surface (64) is formed wider than the inclination guide width (Wr) of the rear guide action surface (66), even a large amount of sorts can be reliably obtained. It can be received by the front guide action surface (64) and dispersed to some extent, and then taken over by the rear guide action surface (66) and further dispersed by the rear guide action surface.

ここで、上部案内片(60c)は、中途部案内片(60b)の傾斜面仮想延長線(Q)よりも下方に配置して、同中途部案内片(60b)よりも緩やかな傾斜面となしているため、上部案内片(60c)により左右方向に幅広い範囲で選別物を受けて、受けた選別物を確実に中途部案内片(60b)に流下・案内させることができる。   Here, the upper guide piece (60c) is disposed below the inclined surface virtual extension line (Q) of the midway guide piece (60b), and has an inclined surface that is gentler than the midway guide piece (60b). Therefore, the upper guide piece (60c) can receive a sorted item in a wide range in the left-right direction, and the received sorted item can be surely flowed down and guided to the midway guide piece (60b).

また、本実施の形態では、選別部(8)により選別された二番還元処理物は、前部フィードパン(26)の前部に臨ませた2番還元コンベア(35)の還元口(35a)より前部選別物案内体(60)の前部に向けて放出させるようにしている。   Moreover, in this Embodiment, the 2nd reduction | restoration processed material sorted by the selection part (8) is the reducing port (35a) of the 2nd reduction | restoration conveyor (35) which faced the front part of the front feed pan (26). ) To the front part of the front sorting object guide (60).

このようにして、二番還元処理物を再度前部選別物案内体(60)により移送・案内しながら均一に分散させて、確実に選別することができる。その結果、一番処理物の回収効率を向上させることができる。   In this way, the second reduced product can be uniformly dispersed while being transported and guided again by the front sorting material guide (60), and can be sorted reliably. As a result, the recovery efficiency of the most processed material can be improved.
