Description
【０００１】[0001]
本考案は、精選別用のグレンシーブをチャフシーブ構造に構成してある脱穀装 置の選別構造に関するものである。 The present invention relates to a threshing device sorting structure in which a fine sieve for fine sorting is formed into a chaff sheave structure.
【０００２】[0002]
脱穀装置の選別部における精選別構造としては、実開平４−７７７４０号公報 で示されるもののように、若干長さのグレンパンに続けて網状のグレンシーブを 張設するものが一般的である。 As a precise selection structure in the selection unit of the threshing device, a structure in which a net-like grain sieve is stretched after a slightly long grain pan is generally used, as shown in Japanese Utility Model Laid-Open No. 4-77740.
【０００３】[0003]
上記構造ではグレンシーブの濾過面積が一定であるが、単位時間当たりの脱穀 処理量に変化に対応し難い点、すなわち、処理物量が少ないときには濾過面積が 過剰になって切れ藁やごみがシーブ後部から１番回収部に落下してしまうとか、 処理物量が多いときには濾過面積が過少になって回収すべき１番物が回収されな いまま後方に移送されてしまうといった不都合点があり、選別性能が十分発揮さ れないことがある。 そこで、実開平４−２１２３１号公報で示されるように、スライドグレンパン 構造により、処理物量に合わせてシーブ面積を変更する技術を採用して上記不都 合点を改善させることが考えられる。この手段では、濾過面積を適切に設定でき ることでかなりの効果が得られるが、処理物量の多い少いに著しい変化がある場 合では対応しきれない面があり、さらなる改善の余地が残されていた。 本考案は、処理物の漏下面積を容易に変更できるチャフシーブに着目し、これ をグレンシーブに代えて用いることにより、著しい処理物量の変化に対応して選 別できる精選別部の提供を目的とするものである。 With the above structure, the filtration area of the Glen Sieve is constant, but it is difficult to respond to changes in the threshing treatment amount per unit time, that is, when the amount of processed material is small, the filtration area becomes excessive and cutting straws and dust from the rear part of the sheave. There is the inconvenience that it falls to the No. 1 recovery unit, or the filtration area becomes too small when the amount of processed material is large, and the No. 1 material to be recovered is transferred to the rear without being recovered, and the sorting performance is poor. It may not be fully exerted. Therefore, as disclosed in Japanese Utility Model Laid-Open No. 4-21231, it is conceivable to adopt the technique of changing the sheave area according to the amount of processed material by using the slide Glen pan structure to improve the above defect point. With this method, it is possible to obtain a considerable effect by setting the filtration area appropriately, but there are some aspects that cannot be dealt with when there is a large change in the amount of treated material and there is room for further improvement. It had been. The present invention focuses on a chaff sheave that can easily change the leak area of the processed material, and by using this instead of the Glen sieve, it is an object of the present invention to provide a fine selection section capable of selecting according to a remarkable change in the processed material amount. To do.

上記目的の達成のために本考案は、揺動選別ケースにおける精選別用の濾過体 を、チャフリップの多数を前後に並設して成るチャフシーブに構成するとともに 、下記〔イ〕〜〔ロ〕の構成を備えて脱穀装置の選別構造を構成してあることを 特徴とするものである。 〔イ〕左右軸心周りで揺動移動可能な前チャフリップの複数を前後に並設して成 る前部シーブと、左右軸心周りで揺動移動可能な後チャフリップの複数で成る後 部シーブとでチャフシーブが構成されている。 〔ロ〕前部シーブにおける全ての前チャフリップを、これらが同時に、かつ、互 いに同一な後倒れ傾斜姿勢でもって揺動移動する状態に連動連結するとともに、 後部シーブにおける全ての後チャフリップを、これらが同時に、かつ、互いに同 一な後倒れ傾斜姿勢でもって揺動移動する状態に連動連結し、更に、前及び後チ ャフリップとを一体的に揺動移動させる連動機構が構成されている。 〔ハ〕前及び後チャフリップの揺動移動により、前後に隣合う前及び後チャフリ ップどうしの間に処理物漏下用の間隙が形成される漏下状態と、前後に隣合う前 及び後チャフリップどうしが重合配置されて間隙が消滅する閉塞状態とが現出可 能であり、後部シーブが漏下状態であり、かつ、前部シーブが閉塞状態となる半 開状態が現出可能であるとともに、この半開状態が左右軸心の所定の角度範囲に 亘って現出可能となるように、前後のチャフリップが連係配置されている。 In order to achieve the above object, the present invention configures a filter body for fine selection in an oscillating selection case into a chaff sheave consisting of a large number of chaflip arranged in front and rear, and also [a] to [b] below. It is characterized in that the sorting structure of the threshing device is configured with the above configuration. [A] A rear sheave consisting of a front sheave, which has a plurality of front and rear flips that can be pivotally moved around the left and right axis, and a rear chaflip, which can be pivotally moved about the left and right axis. A chaff sheave is composed of a partial sheave. [B] All front chaf flips on the front sheave are linked together so that they swing and move at the same time and with the same rearward tilting posture, and all rear chaf flips on the rear sheave are also connected. Are linked together so that they swing at the same time and in the same rearward tilted tilted posture, and further, an interlocking mechanism for swinging the front and rear cha-flip integrally is constructed. There is. [C] Leakage state in which a gap for processing product leakage is formed between the front and rear chaffs adjacent to each other by the swinging movement of the front and rear chaffs, and A closed state in which the rear char flips are overlapped and the gap disappears can appear, and the rear sheave is in a leaking state and the front sheave can be in a closed state, which can be revealed. In addition, the front and rear char flips are linked to each other so that the half-opened state can appear over a predetermined angular range of the left and right axial centers.

構成〔イ〕によるチャフシーブを採用すると、シーブの目合い、すなわち前後 で相隣るチャフリップ板間の間隙幅が変化して漏下面積が変更調節できる。選別 部では、著しく処理物量が多い又は少ないと目合いと濾過面積の双方共に変更し た方が効率が良く、この点において、濾過面積は変更できるが目合いは変更でき ない前記後者の公報のものに比べて本願のものの方が有利になる。 ところで、上記〔イ〕の構成を実施するには、 従来構造におけるグレンパンとグレンシーブとに亘る部分全てをチャフシー ブ化する。 従来構造におけるグレンシーブ部分のみをチャフシーブ化する。 という２通りが考えられるが、の手段では漏下面積を幅広く変更できるが、処 理物量が少ないときにチャフシーブ前部から切れ藁が落ちるおそれがあり、の 手段では処理物量が少ないときにおける切れ藁落下おそれは解消されるが、処理 物量が多いときには漏下面積が不足する傾向がある。 When the chaff sheave according to the configuration [a] is adopted, the mesh size of the sheave, that is, the gap width between the adjacent chaflip plates in the front and rear is changed, and the leakage area can be changed and adjusted. In the sorting section, it is more efficient to change both the mesh size and the filtration area when the amount of processed material is significantly large or small. In this respect, the mesh size and the filtration area can be changed but the mesh size cannot be changed. The one of the present application is more advantageous than the one of the present invention. By the way, in order to implement the configuration of the above-mentioned [a], all the portions extending over the Glen pan and the Glen sheave in the conventional structure are made into chaff sheaves. Only the gren sheave part in the conventional structure is made into a chaff sheave. There are two possible ways to do this. With the method, the leakage area can be widely changed, but when the amount of processed material is small, the straw may fall from the front of the chaff sheave, and with the method, the straw can be used when the processed material is small. Although the risk of falling is eliminated, the leakage area tends to be insufficient when the amount of processed material is large.
【０００６】 そこで、上記構成〔ロ〕，〔ハ〕を採ると、次のような作用が発揮される。 すなわち、図２、図３を参照して説明すると、前チャフリップと後チャフリッ プの先端形状の違いと、チャフリップどうしの重合配置可能構造とにより、刈取 茎稈が一時的に無くなる枕地での回行時には処理物量が極端に少ないので、図２ （ａ）に示すようにチャフシーブが全閉状態となり、切れ藁等が１番物回収部に 落ちないようにする。 作業走行時における処理物量が少ないときには、チャフシーブを若干開き操作 して、図２（ｂ）に示すように前部シーブは閉じるとともに、後部シーブが少し 開く状態にセットし、後部シーブの小なる目合いで、かつ、少ない漏下面積でも って切れ藁の漏下を防ぎつつ良好に選別させることができる。このとき、閉じ状 態の前部シーブにおいて比重差選別作用の発生を期待することができる。 作業走行時における処理物量が普通（中くらい）であるときには、チャフシー ブをある程度開き操作して、図３（ｃ）に示すように、依然として前部シーブは 閉じるとともに、後部シーブがある程度開く状態にセットし、後部シーブの中な る目合いで、かつ、中なる漏下面積でもって切れ藁の漏下を有効に防ぎつつ良好 に選別させることができる。この場合でも前部シーブにおける比重差選別作用を 期待することができる。 そして、処理物量が多いときには、チャフシーブを大きく開き操作して、図３ （ｄ）に示すように、前部シーブが少し開くとともに、後部シーブを大きく開い た状態にセットし、目合いの大なる後部シーブでの大量の漏下作用に目合いの小 なる前部シーブでの穀粒の漏下作用が加わり、切れ藁の１番混入を極力ないよう にしながら大量の処理物を精選別できるようになる。 又、更に処理物量が多いときには、チャフシーブをさらに開き操作し、前部シ ーブが中くらい開くとともに、後部シーブがより大きく開く状態が現出されるよ うにしておいても良い。 以上の、処理物量に応じて目合いと漏下面積とを組合わせて変更調節すること により、処理物量の多少に大きな差があっても、その量に応じた適切なシーブ状 態を現出できるようになる。Therefore, when the above configurations [B] and [C] are adopted, the following actions are exhibited. That is, referring to FIG. 2 and FIG. 3, in a headland where the cutting stems are temporarily lost due to the difference in the tip shape of the front chalip and the rear chalip and the overlapping arrangement structure of the cha flips. Since the amount of processed material is extremely small during the round trip, the chaff sheave will be in the fully closed state as shown in Fig. 2 (a), and the straw etc. will not fall into the No. 1 material collecting section. When the amount of material to be processed during work is small, open the chaf sheave slightly to set the front sheave close and the rear sheave slightly open, as shown in Fig. 2 (b). It is possible to perform good selection while avoiding the leakage of the straw with a small leakage area. At this time, it is possible to expect the occurrence of the specific gravity difference selection action in the closed front sheave. When the amount of processed material during work traveling is normal (medium), the chaf sheave is opened to some extent, and as shown in Fig. 3 (c), the front sheave is still closed and the rear sheave is opened to some extent. It is possible to set and set the rear sheave in good condition, and with the middle leakage area, it is possible to effectively prevent the leakage of the straw and to make a good selection. Even in this case, it is possible to expect a specific gravity difference selection action in the front sheave. When there is a large amount of material to be processed, open the chaff sheave to set the front sheave slightly open and the rear sheave wide open, as shown in Fig. 3 (d). A large amount of leakage from the rear sheave is added to the grain leakage from the front sheave, which has a small meshing effect, so that a large amount of processed products can be selected carefully while minimizing the number 1 mixture of straw. become. Further, when the amount of processed material is further large, the chaff sheave may be further opened so that the front sheave is opened to the middle and the rear sheave is opened more. By changing and adjusting the combination of the mesh and the leakage area according to the amount of processed material, even if there is a large difference in the amount of processed material, the appropriate sheave state can be displayed according to the amount. become able to.

従って、構造が工夫されたチャフシーブで精選別させることにより、単位時間 当たりの処理物量の多少に合わせた選別状態が現出でき、全体としての選別性能 が向上する脱穀装置を提供することができた。 Therefore, by carefully selecting with a chaff sieve with a devised structure, it is possible to provide a threshing device in which a sorting state that matches the amount of processed material per unit time can be revealed and the sorting performance as a whole is improved. .

The rearward tilt angle is set to be the same, and the interlocking mechanism C for integrally swinging the front cha flip 14 and the rear cha flip 15 is configured. Then, due to the swinging movement of the front and rear char flips 14 and 15, a leakage state in which a gap for the leakage of the processed material is formed between the front and rear char flips 14 and 15 which are adjacent to each other in the front and rear, and the front and rear.

プ（１４），（１５）が連係配置されている。1. A filter body for fine sorting in a rocking sorting case (5) is constituted by a chaff sheave (16) formed by arranging a large number of chaf flips (14), (15) in front and back, and A sorting structure of a threshing device having the configurations of [A] to [C]. [A] A front sheave (S) formed by arranging a plurality of front chuck flips (14), which are swingable about the left and right axial centers, in front and rear.
The chaff sheave (16) is composed of f) and a rear sheave (Sr) which is composed of a plurality of rear chaf flips (15) that can swing about the left-right axis. [B] All the front chuck flips (14) in the front sheave (Sf) are interlocked and connected so that they simultaneously swing and move in the same rearward tilted posture, and the rear sheave (Sf). All the rear char flips (15) in (Sr) are interlockingly connected so that they swing and move at the same time and in the same rearward tilted posture, and the front char flip (14) and the rear char flip (14) are connected. An interlocking mechanism (C) that integrally swings the flip (15) is configured. [C] Due to the swinging movement of the front and rear char flips (14) and (15), a gap for processing material leakage is provided between the front and rear char flips (14) and (15) adjacent to each other in the front and rear. A leakage state formed and a closed state in which the front and rear char flips (14) and (15) adjacent to each other in front and rear are overlapped with each other and the gap disappears can appear, and the rear sheave (Sr ) Is a leakage state, and the front sheave (Sf) is in a closed state, and a half-open state can appear, and this half-open state appears over a predetermined angular range of the left and right axial centers. The front and rear cha flips (14) and (15) are arranged in a linked manner so as to be possible.
