(Adjustment of tang fan)
The air outlet 65 of the Karabu wind tunnel 17 opens between a top surface portion 67 positioned above and a bottom surface portion 68 positioned below, and a wind rate 66 is provided between the top surface portion 67 and the bottom surface portion 68 in the middle of the top and bottom. Is provided. Thus, the air outlet 65 is partitioned into an upper air passage 74 between the air divider 66 and the top surface portion 67 and a lower air passage 75 between the air divider 66 and the bottom surface portion 68.

風割66は、送風方向と直交する水平の回動軸66x(図12参照)を回動中心とし、且つ上面69及び下面71,72が送風方向下流側に向かって斜め上向きとなる角度範囲内で回動自在に構成されており、また、風割66の回動軸66xは風割の送風方向中間に位置しており、回動軸66xの上流側及び下流側が上下するように回動するようになっている。風割66の回動軸66xは、その両端部が選別室18の両側壁18Sに軸支されている。さらに、風割66の回動により風割66の水平面に対する傾斜角(以下単に傾斜角ともいう)を最大まで増加させたとき、風割66における唐箕16側の端部が送風口65の底面部68と近接又は接触するように構成されている(図5及び図6参照)。風割66は、脱穀装置の外部に設けた電動モータ205の作動によって回動調節される構成としている。   The air split 66 has an angular range in which a horizontal rotation shaft 66x (see FIG. 12) orthogonal to the air blowing direction is a rotation center, and the upper surface 69 and the lower surfaces 71 and 72 are obliquely upward toward the downstream side in the air blowing direction. Further, the rotation shaft 66x of the air split 66 is positioned in the middle of the air blowing direction, and rotates so that the upstream side and the downstream side of the rotary shaft 66x move up and down. It is like that. Both ends of the rotation shaft 66x of the air split 66 are pivotally supported on both side walls 18S of the sorting chamber 18. Further, when the inclination angle of the airflow 66 with respect to the horizontal plane (hereinafter also simply referred to as the inclination angle) is increased to the maximum by the rotation of the airflow 66, the end of the airflow 66 on the tang 16 side is the bottom surface portion of the air outlet 65.

It is configured to rotate. Although the rotation shaft 67x of the top surface portion 67 is located at the end of the top surface portion 67 on the side of the Karatsu 16 in the illustrated example, it can be located at the middle of the blowing direction or at the downstream side of the blowing direction, either way. What is necessary is just to rotate so that the downstream side of the top | upper surface part 67 may go up and down. Both ends of the rotation shaft 67x of the top surface portion 67 are also pivotally supported on both side walls 18S of the sorting chamber 18.

このような構造においては、唐箕16から供給される一定量の風の上側風路74及び下側風路75に対する配分比率は、上側風路74及び下側風路75の開口度の比率によって定まる。よって、下側風路75の開口度が減少する方向に、天面部67及び風割66が同じ方向に連動して回動すると、下側風路75の風量は減少し、反対に上側風路74の風量は増加するとともに、下側風路75の風向は風割66の下面の角度変化に応じて変化し、上側風路74の風向は天面部67の角度変化および風割66の下面の角度変化に応じて変化する。一方、下側風路75の開口度が増加する方向に、天面部67及び風割66が同じ方向に連動して回動すると、下側風路75の風量は増加し、反対に上側風路74の風量は減少する。下側風路75の風向は風割66の下面の角度変化に応じて変化し、上側風路74の風向は天面部67の角度変化および風割66の下面の角度変化に応じて変化する。つまり、上側風路74及び下側風路75の風向及び風量を同時に調整できるようになる。   In such a structure, the distribution ratio of a certain amount of wind supplied from the tang 16 to the upper air passage 74 and the lower air passage 75 is determined by the ratio of the opening degrees of the upper air passage 74 and the lower air passage 75. . Therefore, when the top surface portion 67 and the wind split 66 rotate in the same direction in the direction in which the opening degree of the lower air passage 75 decreases, the air volume of the lower air passage 75 decreases, and conversely the upper air passage. As the airflow of the airflow 74 increases, the airflow direction of the lower air passage 75 changes according to the angle change of the lower surface of the airflow 66, and the airflow direction of the upper airway 74 changes the angle of the top surface portion 67 and the lower surface of the airflow 66. It changes according to the angle change. On the other hand, if the top surface portion 67 and the wind split 66 are rotated in the same direction in the direction in which the opening degree of the lower air passage 75 increases, the air volume of the lower air passage 75 increases, and conversely the upper air passage. The airflow at 74 decreases. The wind direction of the lower air passage 75 changes in accordance with the change in angle of the lower surface of the wind divider 66, and the wind direction of the upper air passage 74 changes in accordance with the change in angle of the top surface portion 67 and the lower surface of the wind divider 66. That is, the wind direction and the air volume of the upper air passage 74 and the lower air passage 75 can be adjusted simultaneously.

(処理物量検出センサ)
風割66及び天面部67の傾斜角は処理物量に関係なく固定としても良いが、揺動選別棚20の上の処理物の量を検出する処理物量検出センサ95を設け、この処理物量検出センサ95の検出結果に基づき、棚上処理物の量が増加したときに風割66及び天面部67の水平面に対する傾斜角を減少させ、棚上処理物の量が減少したときに風割66及び天面部67の水平面に対する傾斜角を増加させる制御装置(図示略)を設けるのも好ましい。これにより、処理物量に増減があっても、揺動選別棚20上の処理物量検出結果に応じて、風割66及び天面部67の傾斜角が適切に自動調整され、最適な穀粒損失と選別状態を得ることができる。
(Processed quantity detection sensor)
Although the inclination angle of the air split 66 and the top surface portion 67 may be fixed regardless of the amount of processed material, a processed material amount detection sensor 95 for detecting the amount of processed material on the swing sorting shelf 20 is provided, and this processed material amount detection sensor is provided. On the basis of the detection result of 95, when the amount of the processed material on the shelf increases, the inclination angle of the air split 66 and the top surface portion 67 with respect to the horizontal plane is decreased, and when the amount of the processed material on the shelf decreases, It is also preferable to provide a control device (not shown) that increases the inclination angle of the surface portion 67 with respect to the horizontal plane. As a result, even if there is an increase or decrease in the amount of processed material, the inclination angle of the wind rate 66 and the top surface portion 67 is automatically adjusted appropriately according to the detected result of the processed material amount on the swing sorting shelf 20, and the optimum grain loss and A sorting state can be obtained.

処理物量検出センサ95は、公知の接触又は非接触センサを用いることにより構成することができる。図示例では、二番処理室40の受板42における終端側(二番処理物還元口側又は前端側)部分と、刺さり粒回収室11Eの中間隔壁11Kの下端部がセンサステー95Sにより連結され、このセンサステー95Sにポテンションメータ等の回転量検出装置(請求項における「センサ」)96が取り付けられるとともに、この回転量検出センサ96の検出軸96xにフロート(接触子)97が吊り下げ状態で取り付けられており、このフロート97が、揺動選別棚20の移送棚22上を移動する被処理物に接触して、被処理物の移動方向に回転しつつ持ち上がり、その回転量が、移送棚22上を移動する被処理物の層厚として回転量検出装置96により検出されるように構成されている。   The processing amount detection sensor 95 can be configured by using a known contact or non-contact sensor. In the illustrated example, a terminal side (second treatment product return port side or front end side) portion of the receiving plate 42 of the second processing chamber 40 and the lower end portion of the intermediate partition wall 11K of the stinging particle collection chamber 11E are connected by a sensor stay 95S. A rotation amount detection device (“sensor” in the claims) 96 such as a potentiometer is attached to the sensor stay 95S, and a float (contactor) 97 is suspended from the detection shaft 96x of the rotation amount detection sensor 96. The float 97 comes into contact with the workpiece to be moved on the transfer shelf 22 of the swing sorting shelf 20 and is lifted while rotating in the moving direction of the workpiece. The rotation amount detection device 96 detects the layer thickness of the object to be processed moving on the shelf 22.

また、図示例のようにフロート97が回動するタイプの場合、フロート97の回動中心(つまり図示例では検出軸96x)が、二番還元物の流れ又は棚上処理物全体の流れに対して略直角となり、平面視で揺動選別棚20の揺動方向に対して傾斜するように構成するのが好ましい。これにより、棚上処理物の流れ方向と、これに接触するフロート97の回動方向が一致するか又は近くなるため、フロート97が円滑に動作し、処理物量の変化に対して正確かつ敏感に反応するようになる。   In the case of the type in which the float 97 rotates as in the illustrated example, the rotation center of the float 97 (that is, the detection shaft 96x in the illustrated example) is relative to the flow of the second reduced product or the entire processed product on the shelf. It is preferable that the configuration is substantially right-angled and inclined with respect to the swinging direction of the swing sorting shelf 20 in a plan view. As a result, the flow direction of the processed material on the shelf and the rotation direction of the float 97 in contact with the same coincide with each other or close to each other, so that the float 97 operates smoothly and is accurate and sensitive to changes in the amount of processed material. It will react.

この場合、フロート97の作動をより円滑にするために、フロート97における回動中心方向一方側、特に図示例のように移送棚22の移送方向下流側に、フロート97の回動中心に対して略直交する方向(センサフロート97の回動方向と略平行)に延在する寄せ板98を立設するのも好ましい形態である。これにより、移送棚22による揺動作用により棚上処理物の移動方向がずれていくとしても、そのフロート97近傍では寄せ板98により移動方向が規制されるため、棚上処理物の流れ方向と、これに接触するフロート97の回動方向が略一致し、フロート97がより一層円滑に動作するようになる。   In this case, in order to make the operation of the float 97 smoother, with respect to the rotation center of the float 97, one side in the rotation center direction in the float 97, particularly on the downstream side in the transfer direction of the transfer shelf 22 as in the illustrated example. It is also a preferable form that a close-up plate 98 extending in a direction substantially orthogonal (substantially parallel to the rotation direction of the sensor float 97) is erected. As a result, even if the moving direction of the processed product on the shelf shifts due to the swinging action by the transfer shelf 22, the moving direction is regulated by the approach plate 98 in the vicinity of the float 97. The rotation direction of the float 97 in contact therewith substantially coincides, and the float 97 operates more smoothly.

また、フロート97の形状は、図示例のように、少なくとも棚上処理物と接触する部分(図示例では棚上処理物が無い非接触状態で、棚上処理物の移動方向上流側の面)が、棚上処理物の摺動方向の中間部ほど張り出す弧状曲面であるのが好ましい。   In addition, the shape of the float 97 is at least a portion in contact with the processed product on the shelf as in the illustrated example (in the illustrated example, the surface on the upstream side in the movement direction of the processed product in the non-contact state where there is no processed product on the shelf) However, it is preferable that it is an arcuate curved surface that protrudes toward the middle part in the sliding direction of the processed material on the shelf.

他方、一般に移送棚22上においては処理物量が偏在し、特に二番処理物還元口43の下方近傍における処理物量が最も多くなる。よって、処理物量検出センサ95は、二番処理物還元口43の近傍における揺動選別棚20の棚上処理物の量を検出するように構成するのが望ましい。このため、図示例ではフロート97を二番処理物還元口43の近傍に配置している。   On the other hand, the amount of processed material is generally unevenly distributed on the transfer shelf 22, and the amount of processed material in the vicinity of the lower portion of the second processed material reducing port 43 is particularly large. Therefore, it is desirable that the processed material amount detection sensor 95 is configured to detect the amount of processed material on the shelf of the swing sorting shelf 20 in the vicinity of the second processed material return port 43. For this reason, in the illustrated example, the float 97 is disposed in the vicinity of the second processed material reducing port 43.

(シーブ清掃装置)
図5〜図7、図10、図14及び図15に示すように、本実施形態では、第一シーブ23上を往復移動することにより清掃を行う清掃部材80が設けられている。より詳細には、第一シーブ23は左右方向に所定の間隔を空けて配置された複数の清掃部材80,80,80…を備えており、この清掃部材80は図19〜図22に詳細に示すように、前後方向に沿うプレート部81(請求項におけるプレート81)と、第一シーブ23の各シーブ部材23bの上面に接触して付着物を除去するスクレーパ部82(請求項におけるスクレーパ82)を有するものである。
(Sheave cleaning device)
As shown in FIGS. 5 to 7, 10, 14, and 15, in this embodiment, a cleaning member 80 that performs cleaning by reciprocating on the first sheave 23 is provided. More specifically, the first sheave 23 includes a plurality of cleaning members 80, 80, 80... Arranged at predetermined intervals in the left-right direction. This cleaning member 80 is shown in detail in FIGS. As shown, the plate portion 81 (the plate 81 in the claims) along the front-rear direction and the scraper portion 82 that contacts the upper surface of each sheave member 23b of the first sheave 23 to remove the deposits (the scraper 82 in the claims). It is what has.

これら清掃部材80,80,80…は、図15及び図16に詳細に示す-ように、前後の連結部材83,83と左右の補強板84,84によって一体的に連結してユニットTを形成し、このユニットTを第一シーブ23に対して左右横方向(シーブ部材23bの長手方向)に往復移動可能に支持している。また図22に示すように、プレート部81は上下方向に沿う垂直姿勢で立設されており、そして、各プレート81にはシーブ部材23bの断面形状に合わせたガイド穴81hを穿設し、各ガイド穴81hに各シーブ部材23bを挿通してスライド案内する構成としている。   These cleaning members 80, 80, 80..., As shown in detail in FIGS. 15 and 16, are integrally connected by front and rear connecting members 83, 83 and left and right reinforcing plates 84, 84 to form a unit T. The unit T is supported so as to be reciprocally movable in the lateral direction (longitudinal direction of the sheave member 23b) with respect to the first sheave 23. Further, as shown in FIG. 22, the plate portion 81 is erected in a vertical posture along the vertical direction, and each plate 81 is provided with a guide hole 81h that matches the cross-sectional shape of the sheave member 23b. Each sheave member 23b is inserted into the guide hole 81h and guided to slide.

スクレーパ部82は、上下方向に傾斜するシーブ部材23bの傾斜上面に接触して摺接移動により付着物を除去するものである。本実施形態のスクレレーパ部82は、移動方向に対して所定角度に傾斜する刃縁82aをプレート部81を挟んで左右対称に有し、平面視で略ハの宇型の刃縁82a,82aを有する形状となっており、このような形状によって左右の往復動に対する付着物の除去が無理なく確実に行えるようになっている。また、このスクレーパ部82は、正面硯で山型の傾斜角を保持すべく昇り傾斜面82s,82s(図19〜図21参照)が設けられ、横方向への移動に伴いその昇り傾斜面82s,82sによって各シーブ部材23b面上の付着物が上方に掬い上げられるようになっている。スクレーパ部82の最突出端部82eは、シーブ部材23bの折り曲げ稜線と合致させた構成としてあり、シーブ部材23bの折り曲げ部に溜まった藁屑や塵埃の除去が容易に行えるようにしている。尚、各シーブ部材23bのガイド穴81hの内面とシーブ部材23の外面の間には、穀粒の枝梗が入り込む程度の隙間を設けるとよい。   The scraper portion 82 contacts the inclined upper surface of the sheave member 23b that is inclined in the vertical direction, and removes adhering substances by sliding movement. The scraper portion 82 of the present embodiment has blade edges 82a that are inclined at a predetermined angle with respect to the moving direction, symmetrically across the plate portion 81, and substantially U-shaped blade edges 82a and 82a in plan view. With such a shape, it is possible to reliably remove the deposits with respect to the left and right reciprocation. Further, the scraper portion 82 is provided with ascending inclined surfaces 82s and 82s (see FIGS. 19 to 21) so as to maintain a mountain-shaped inclination angle at the front surface, and the ascending inclined surface 82s as it moves in the lateral direction. , 82s allows the deposits on the surface of each sheave member 23b to be scooped upward. The most projecting end portion 82e of the scraper portion 82 is configured to coincide with the bent ridge line of the sheave member 23b, so that the dust and dust accumulated in the bent portion of the sheave member 23b can be easily removed. In addition, it is good to provide the clearance gap between the inside of the guide hole 81h of each sheave member 23b, and the outer surface of the sheave member 23 so that the branch of a grain may enter.

プレート部81とスクレーパ部82とは別体とすることもできるが、本実施形態のように一体とし、特に合成樹脂材で一体成形した構成とすると、製造容易性、コスト、メンテナンス性の点で優れる。また、シーブ23との間の摺動抵抗が軽減され、このプレート部81およびスクレーパ部82の往復移動を円滑化することができる。   The plate portion 81 and the scraper portion 82 can be separated. However, as in the present embodiment, the plate portion 81 and the scraper portion 82 are integrally formed, and in particular, when integrally formed with a synthetic resin material, in terms of manufacturability, cost, and maintainability. Excellent. Further, sliding resistance with the sheave 23 is reduced, and the reciprocating movement of the plate portion 81 and the scraper portion 82 can be facilitated.

各清掃部材80を駆動するための清掃部材駆動装置V(請求項における駆動装置V)は、本実施形態では、ズ16、図17、図18に示すように、駆動モータ85と、互い違いに引き操作する一対の操作ケーブル86b,86bと、往復回動する天秤アーム87と、天秤アーム軸87aと、往復回動する揺動アーム88等の連動機構から構成する。即ち、駆動モータ85の回転駆動により、操作ケーブル86b,86b、天秤アーム87、天秤アーム軸87a、揺動アーム88等の連動機構を介して、各清掃部材80が左右横方向に往復動するように構成している。すなわち、駆動モータ85を駆動すると、クランクアーム86の回転により、クランクピン86pに対して連結された一対の操作ケーブル86b,86bが互い違いに引き操作され、天秤アーム87の往復回動によって天秤アーム軸87aを回動中心として揺動アーム88が左右に往復揺動し、この揺動アーム88の長孔88hに対して移動自在に挿入された89を有する清掃部材80が左右横方向へ強制的に往復動されるようになっている。この左右横方向の往復移動範囲(移動ストローク)が、各清掃部材80,80,80…間の配置ピッチPよりも大きくされていると、スクレーパ部82がシーブ部材23bの全域にわたって作用するため好ましい。   In this embodiment, the cleaning member drive device V (drive device V in the claims) for driving each cleaning member 80 is alternately pulled with the drive motor 85 as shown in FIGS. 16, 17, and 18. A pair of operating cables 86b, 86b to be operated, a balance arm 87 that reciprocates and turns, a balance arm shaft 87a, and an interlocking mechanism such as a swing arm 88 that reciprocates and turns. That is, the rotational drive of the drive motor 85 causes each cleaning member 80 to reciprocate in the left and right lateral directions via interlocking mechanisms such as the operation cables 86b and 86b, the balance arm 87, the balance arm shaft 87a, and the swing arm 88. It is configured. That is, when the drive motor 85 is driven, the pair of operation cables 86b and 86b connected to the crank pin 86p are alternately pulled by the rotation of the crank arm 86, and the balance arm shaft is reciprocated by the reciprocating rotation of the balance arm 87. A swinging arm 88 reciprocally swings left and right about a pivot 87a, and a cleaning member 80 having 89, which is movably inserted into a long hole 88h of the swinging arm 88, is forcibly moved laterally. It is designed to reciprocate. It is preferable that the reciprocating range (moving stroke) in the horizontal direction is larger than the arrangement pitch P between the cleaning members 80, 80, 80... Because the scraper portion 82 acts over the entire area of the sheave member 23b. .

この形態では、清掃部材80,80,80…の揺動が連続的になされるが間欠的でも良い。また、清掃部材80,80,80…の駆動モータ85を脱穀操作、例えば脱穀クラッチの入り操作に連動して自動で駆動を開始するようにするのが好ましいが、非連動として任意のスイッチにより駆動を開始する構成としても良い。さらに、本実施形態のように、クランクピン86pと操作ケーブル86bとはスプリング86s及びプレート86tを介して連結保持させると、操作ケーブル86bに無理な加重が掛からないため好ましい。   In this embodiment, the cleaning members 80, 80, 80... Are continuously swung, but may be intermittent. Further, it is preferable to automatically drive the driving motor 85 of the cleaning members 80, 80, 80... In conjunction with the threshing operation, for example, the operation of entering the threshing clutch. It is good also as a structure which starts. Furthermore, as in the present embodiment, it is preferable that the crank pin 86p and the operation cable 86b are connected and held via the spring 86s and the plate 86t because an excessive load is not applied to the operation cable 86b.

揺動アーム88の配置は適宜設計することができるが、本実施形態では図7に示すように揺動選別棚20の上方からの処理物が多量に落下する側とは反対側の側部に配置している。本実施形態では、揺動選別棚20上への処理物落下量はフィードチェーン13B側で少なく、二番処理胴41側が多くなるため、揺動選別棚20のフィードチェーン13B側に揺動アーム88を配置することによって揺動選別棚20の左右バランスを均等化することができる。また、揺動アーム88部は、移送棚22の下方で唐箕風洞17の上方後方部の空間部に設けることで、揺動選別棚20部の死角部を有効に利用でき、コンパクトに配置構成することができる。本実施形態では、天秤アーム87や操作ケーブル86bについても移送棚22と唐箕風洞17との間に配置した構成としている。   The arrangement of the swing arm 88 can be designed as appropriate. In this embodiment, as shown in FIG. 7, the swing arm 88 is disposed on the side opposite to the side from which a large amount of processed material falls from above the swing sorting shelf 20. It is arranged. In the present embodiment, the amount of processed material dropped onto the swing sorting shelf 20 is small on the feed chain 13B side and larger on the second processing cylinder 41 side, so the swing arm 88 on the feed chain 13B side of the swing sorting shelf 20 is large. It is possible to equalize the left / right balance of the rocking sorting shelf 20 by arranging. Further, the swing arm 88 part is provided in the space part in the upper rear part of the Kara wind tunnel 17 below the transfer shelf 22, so that the blind spot part of the swing sorting shelf 20 part can be used effectively, and the arrangement is made compact. be able to. In the present embodiment, the balance arm 87 and the operation cable 86b are also arranged between the transfer shelf 22 and the Karabu wind tunnel 17.

図14に示すように、揺動選別棚20を構成する揺動選別ケースの前壁20a部には、揺動アーム88を揺動案内するガイド孔20dが設けられ、このガイド孔20d部には、当該ガイド孔20dを弾性的に閉塞するスリットを有する弾性シール部材(ブラシ体)20gが設けられている。揺動アーム88は、ガイド孔20dに沿ってシール部材20gのスリットを押し分けながら揺動運動することになるため、シール部材20gによってガイド孔20dが常に閉塞され、ガイド孔20dからの籾や藁屑や塵埃の流出が防止される。   As shown in FIG. 14, a guide hole 20d for swinging and guiding the swing arm 88 is provided in the front wall 20a portion of the swing sorting case constituting the swing sorting shelf 20, and this guide hole 20d portion has a guide hole 20d. An elastic seal member (brush body) 20g having a slit for elastically closing the guide hole 20d is provided. Since the swing arm 88 swings while pushing the slit of the seal member 20g along the guide hole 20d, the guide hole 20d is always closed by the seal member 20g, and soot and dust from the guide hole 20d are blocked. And dust outflow is prevented.

本実施形態のようなクランクアーム86の回転運動によって清掃部材80,80,80…を揺動駆動するものでは、清掃部材80,80,80…の作動(移動)速度が作動範囲の中央部で速く、作動範囲の両端側で遅くなるように構成することができる。これによれば、中央部での拡散効果も大きくスクレーパ部82により寄せられた藁屑や塵埃が速やかに除去されることになる。また、スクレーパ部82の作動トルクを作動範囲の中央部より両端側を大きくすることで、スクレーパ部82により寄せられ残った藁屑や塵埃を逆方向に駆動する際、必要なトルクが大きいため、スクレーパ部82の作動が円滑に行える。   When the cleaning members 80, 80, 80... Are driven to swing by the rotational movement of the crank arm 86 as in this embodiment, the operation (movement) speed of the cleaning members 80, 80, 80. It can be configured to be fast and slow at both ends of the operating range. According to this, the diffusion effect in the central part is also large, and the dust and dust gathered by the scraper part 82 are quickly removed. In addition, by increasing the operating torque of the scraper unit 82 at both ends from the center of the operating range, when driving the scraps and dust left behind by the scraper unit 82 in the reverse direction, the necessary torque is large, The operation of the scraper unit 82 can be performed smoothly.

清掃部材80の摩耗による交換や、清掃部材80とシーブ部材23bとの間に詰まった藁屑の除去等、清掃部材80を第一シーブ23から取り外すメンテナンスが必要になることがある。このため、本実施例の第一シーブ23では、シーブ部材23bからなるシーブ本体部の両端部を支持する板状のシーブ支持部23sのうち、いずれか一方のシーブ支持部23sに、図24及び図25に示すように各シーブ部材23bの端部を抜き差し可能に挿入するシーブ部材挿入孔23hを設けるとともに、他方のシーブ支持部23sに各シーブ部材23bを溶接等により固定し、一方のシーブ支持部23sのシーブ部材挿入孔23hに他方のシーブ支持部23sから櫛状に突出する各シーブ部材23bの端部を挿入した状態で、シーブ部材23bの下方において両方のシーブ支持部23s間にわたる棒状等の連結部材23fを介在させ、連結部材23fと両方のシーブ支持部23sを図示しないボルトにより着脱自在に連結している。このボルトを外すことにより、一方のシーブ支持部23sを、他方のシーブ支持部23sに固定されたシーブ部材23bに対して取り外してシーブ部材23bの一端を開放した状態で、この開放端からシーブ部材23bに対する清掃部材80の抜き取り及び挿入することができる。よって、第一シーブ23に対して清掃部材80を容易に着脱でき、清掃部材80とシーブ23との間に詰まる藁屑を確実に除去できる等、シーブ23の清掃を十分に行うことができ、また清掃部材80の交換も容易となる。またこの構造では、連結部材23fによりシーブユニットの剛性も十分に確保される。   Maintenance may be required to remove the cleaning member 80 from the first sheave 23, such as replacement due to wear of the cleaning member 80 or removal of swarf clogged between the cleaning member 80 and the sheave member 23b. For this reason, in the first sheave 23 of the present embodiment, one of the sheave support portions 23s of the plate-like sheave support portions 23s that supports both ends of the sheave body portion made of the sheave member 23b is replaced with FIG. As shown in FIG. 25, sheave member insertion holes 23h are provided for inserting the end portions of the respective sheave members 23b so that they can be inserted and removed, and each sheave member 23b is fixed to the other sheave support portion 23s by welding or the like. A rod-like shape extending between both sheave support portions 23s below the sheave member 23b with the end portions of each sheave member 23b protruding in a comb shape from the other sheave support portion 23s inserted into the sheave member insertion hole 23h of the portion 23s The connection member 23f is interposed, and the connection member 23f and both sheave support portions 23s are detachably connected by bolts (not shown). By removing this bolt, one sheave support portion 23s is removed from the sheave member 23b fixed to the other sheave support portion 23s and one end of the sheave member 23b is opened, and the sheave member is opened from the open end. The cleaning member 80 can be pulled out and inserted into 23b. Therefore, the cleaning member 80 can be easily attached to and detached from the first sheave 23, and the sheave 23 can be sufficiently cleaned, such as the debris clogged between the cleaning member 80 and the sheave 23 can be reliably removed. Further, the cleaning member 80 can be easily replaced. Further, in this structure, the rigidity of the sheave unit is sufficiently ensured by the connecting member 23f.

シーブ部材挿入孔23hの寸法・形状はシーブ部材23bの寸法・形状に合わせても良いが、本実施形態のように、寸法についてはある程度の遊び(シーブ部材挿入孔23hとシーブ部材23bとの隙間、ガタ)を持たせると、シーブ支持部23sに対するシーブ部材23bの固定精度や装置駆動時のシーブ部材23bの歪をこの遊びで吸収することができ、清掃部材80の作動を円滑化できる。   The size / shape of the sheave member insertion hole 23h may be matched to the size / shape of the sheave member 23b. However, as in the present embodiment, the size of the sheave member insertion hole 23h is limited to some extent (the gap between the sheave member insertion hole 23h and the sheave member 23b). ), The accuracy of fixing the sheave member 23b to the sheave support 23s and the distortion of the sheave member 23b when the apparatus is driven can be absorbed by this play, and the operation of the cleaning member 80 can be smoothed.

また、上述の構成に代えて、スクレーパ部82をリードカムで左右方向に往復摺動させる構成とし、このリードカムを回転駆動する電動モータを、揺動選別棚20に一体的に取り付けて構成してもよい。このように構成すれば、上述のような脱穀装置本体側から揺動選別棚20へのワイヤーの配索が不要となり、構成が簡素化されると共に、耐久性が向上する。また、上述のワイヤーによる連繋機構に代えて、ロッドからなるリンク機構を用いてもよい。   Further, instead of the above-described configuration, the scraper 82 may be reciprocated in the left-right direction with a lead cam, and an electric motor that rotationally drives the lead cam may be integrally attached to the swing sorting shelf 20. Good. If comprised in this way, the wiring of the above-mentioned threshing device main body side to the rocking | swiveling sorting shelf 20 becomes unnecessary, and while a structure is simplified, durability improves. Moreover, it may replace with the connection mechanism by the above-mentioned wire, and may use the link mechanism which consists of a rod.

(シーブ着脱機構)
特徴的には、図14及び図15に示すように、第一シーブ23は揺動選別棚20の上方への取り外し及び揺動選別棚20の上方からの取り付けが可能なように取り付けられる。これにより、図8及び図13に示すようにフィードチェーン部9および蓋体11Zを開くことにより、点検口11Sを介して扱室11内に手を入れ、第一シーブ23を上方に取り外して点検口11Sから機外に取り出し、また反対に機内に入れて組み立てることができるため、第一シーブ23に詰まった藁屑を除去する等のメンテナンスを、揺動選別棚20の分解を要せずに極めて容易に行うことができるようになる。また、本実施形態の場合、選別網の上流側部分が第一シーブ23の直ぐ下に位置しており、第一シーブ23を機外に取り外すことにより、その下方に位置する選別網28が点検口11S側に露出するため、揺動選別棚20を取り外すことなく、点検口11Sを介して揺動選別棚20上方より機内に備え付けられている選別網28の清掃等のメンテナンスを行うことも可能となる。
(Sheave attachment / detachment mechanism)
Characteristically, as shown in FIGS. 14 and 15, the first sheave 23 is attached so that it can be removed from the swing sorting shelf 20 and attached from above the swing sorting shelf 20. Accordingly, as shown in FIGS. 8 and 13, by opening the feed chain portion 9 and the lid 11Z, a hand is put into the handling chamber 11 through the inspection port 11S, and the first sheave 23 is removed upward for inspection. Since it can be taken out of the machine from the mouth 11S and put into the machine on the contrary, maintenance such as removing the dust clogged in the first sheave 23 can be performed without requiring disassembly of the swing sorting shelf 20. This can be done very easily. In the case of the present embodiment, the upstream side portion of the sorting screen is located immediately below the first sheave 23. By removing the first sheave 23 outside the machine, the sorting screen 28 located below the first sheave 23 is inspected. Since it is exposed to the mouth 11S side, it is possible to perform maintenance such as cleaning of the sorting screen 28 provided in the machine from above the swing sorting shelf 20 through the inspection port 11S without removing the swing sorting shelf 20. It becomes.

第一シーブ23の上方着脱を可能とする構造は適宜定めることができるが、第一シーブ23に上述のような清掃部材80を取り付ける場合には、清掃部材80に対する伝動を第一シーブ23の上方移動に伴い分離し、また第一シーブ23の下方移動に伴い連結できる構造が必要となる。このため本実施形態では、図14〜図16に示すように、清掃部材80の適所、例えば図示のようにフィードチェーン13B側の端に位置する清掃部材80のプレート部81の側面から第一シーブ23の下方に連結ピン89pを突出させ、この連結ピン89pにカラー89cを取り付けて前述の突出部89を構成している。第一シーブ23を取り付ける際には、清掃部材80を装着した第一シーブ23を揺動選別棚20上に載せて、突出部89を前述の揺動アーム88の長孔(本発明の係合部に相当する)88hに挿入することにより伝動を連結する。第一シーブ23は、両側部のシーブ支持部23sにおいて揺動選別棚20にボルト23v等の着脱固定手段により固定される。第一シーブ23を取り外す際には、揺動選別棚20に対する第一シーブ23の固定を解除した後、図14及び図15に示すように、清掃部材80を装着したままの第一シーブ23を揺動選別棚20の上方に持ち上げ、突出部89を揺動アーム88から引き抜くことにより伝動の分離とともに第一シーブ23を取り外すことができる。なお、揺動アーム88の長孔88hは図示例のように孔部分が先端に達しておりフォーク状をなす形態も含む。   The structure enabling the first sheave 23 to be attached and detached can be determined as appropriate. However, when the cleaning member 80 as described above is attached to the first sheave 23, the transmission to the cleaning member 80 is transmitted above the first sheave 23. A structure is required that can be separated as the first sheave 23 moves, and that the first sheave 23 can be connected as it moves downward. For this reason, in the present embodiment, as shown in FIGS. 14 to 16, the first sheave is formed from an appropriate position of the cleaning member 80, for example, from the side surface of the plate portion 81 of the cleaning member 80 located at the end of the feed chain 13 </ b> B as shown in the drawing. A connecting pin 89p is projected below 23, and a collar 89c is attached to the connecting pin 89p to constitute the protruding portion 89 described above. When attaching the first sheave 23, the first sheave 23 fitted with the cleaning member 80 is placed on the swing sorting shelf 20, and the projecting portion 89 is inserted into the long hole (the engagement of the present invention). The transmission is connected by inserting into 88h. The first sheave 23 is fixed to the swing sorting shelf 20 by a detachable fixing means such as a bolt 23v at the sheave support portions 23s on both sides. When removing the first sheave 23, after the first sheave 23 is fixed to the swing sorting shelf 20, as shown in FIGS. 14 and 15, the first sheave 23 with the cleaning member 80 mounted thereon is removed. The first sheave 23 can be removed together with the separation of the transmission by lifting it above the swing sorting shelf 20 and pulling out the protrusion 89 from the swing arm 88. In addition, the long hole 88h of the swing arm 88 includes a fork-like form in which the hole portion reaches the tip as in the illustrated example.

なお、本実施形態のように移送棚22上から第一シーブ23上にわたる寄せ板98を取り付ける場合は、図14に示すように寄せ板98を着脱可能に取り付けるようにし、取り外した寄せ板98を点検口11Sから取り出し可能とすることにより、寄せ板98を先に取り外すことができ、寄せ板98の邪魔無くして第一シーブ23を上方に取り外すことができるようになる。   In addition, when attaching the approaching plate 98 extending from the transfer shelf 22 to the first sheave 23 as in the present embodiment, the approaching plate 98 is detachably attached as shown in FIG. By making it possible to remove the inspection plate 11S from the inspection port 11S, the approach plate 98 can be removed first, and the first sheave 23 can be removed upward without obstruction of the approach plate 98.

また、扱室11の下側に張設される受網15のうちのフィードチェーン部9側の端部が、受網15の下側において前後方向に沿って架設された棒状等の受網固定部材15Uに係合および離脱自在な構成とされており、フィードチェーン13Bを開いた状態で、受網固定部材15Uが点検口11Sを横切る場合、この受網固定部材15Uが第一シーブ23の着脱等の作業の邪魔になる。よってこのような場合、図5及び図13に示すように、受網固定部材15Uの形状を、点検口11Sより前側及び後側の部位であって且つ点検口11Sと重なる上下方向範囲に、受網15のフィードチェーン部9側の端部に係合する係合部15fを有するとともに、点検口11Sと重なる前後方向中間部に、受網15のフィードチェーン部9側の端部が係合することなく側面視で点検口11Sを迂回するU字状をなすように下方に湾曲した湾曲部15wを有する形状とするのが好ましい。この湾曲部15wと受網15のフィードチェーン部9側の端部との間に形成された空間を経て、点検口11Sから第一シーブ23を外部へ取り出すことができるので、点検口11Sからの第一シーブ23の着脱等の作業空間が拡大し、作業性が向上する。   Also, the end of the feed chain portion 9 side of the receiving net 15 that is stretched under the handling chamber 11 is fixed to a receiving net such as a rod that is constructed along the front-rear direction on the lower side of the receiving net 15. When the receiving net fixing member 15U crosses the inspection port 11S with the feed chain 13B open, the receiving net fixing member 15U can be attached to and detached from the first sheave 23. Etc. Therefore, in such a case, as shown in FIG. 5 and FIG. 13, the shape of the receiving net fixing member 15U is received in the vertical range that is the front and rear portions of the inspection port 11S and overlaps the inspection port 11S. It has an engaging portion 15f that engages with the end portion of the mesh 15 on the feed chain portion 9 side, and the end portion of the receiving mesh 15 on the feed chain portion 9 side engages with an intermediate portion in the front-rear direction that overlaps the inspection port 11S. It is preferable to have a shape having a curved portion 15w that is curved downward so as to form a U shape that bypasses the inspection port 11S when viewed from the side. The first sheave 23 can be taken out from the inspection port 11S through the space formed between the curved portion 15w and the end portion of the receiving net 15 on the feed chain portion 9 side. The work space for attaching and detaching the first sheave 23 is expanded, and workability is improved.

(その他)
(A) 扱胴10後方側の処理効率を向上させるために、図26に示すように扱胴10を前扱胴101と後扱胴102に分割し、前扱胴101よりも後扱胴102の速度を速く又は回転数を高くすることが知られているが、その場合には第一シーブ23における後扱胴102下方部位に藁屑や塵埃が付着し易いだけでなく、強い扱胴起風により第一シーブ23上の処理物が左右方向一方側に寄り、選別能の低下をもたらすおそれがある。よって、第一シーブ23の前後方向範囲のうち少なくとも後扱胴102下方部位には清掃部材を設け、第一シーブ23上に付着する藁屑等の除去効率を高め、また清掃部材80の往復移動により第一シーブ23上の処理物を平らに均すのは好ましい。
(Other)
(A) In order to improve the processing efficiency on the rear side of the handling cylinder 10, the handling cylinder 10 is divided into a front handling cylinder 101 and a rear handling cylinder 102 as shown in FIG. However, in this case, not only dust or dust easily adheres to the lower part of the rear handling cylinder 102 in the first sheave 23 but also a strong handling cylinder. The processed material on the first sheave 23 may be shifted to one side in the left-right direction due to the wind, which may cause a reduction in sorting ability. Accordingly, a cleaning member is provided at least in a lower part of the rear handling cylinder 102 in the front-rear direction range of the first sheave 23 to improve the removal efficiency of the dust and the like adhering to the first sheave 23, and the cleaning member 80 is reciprocated. It is preferable to level the treated material on the first sheave 23 by the following method.

(B) 図29に示すように、受網15の孔の目合いを受網15の後側に位置する孔151b〜151d,152b〜152dについて前側に位置する孔151a,152aよりも大きくすると、脱穀処理物の受網15通過効率が上昇して穀粒の回収効率は高まるが、藁屑等の受網15通過も促進されるため、第一シーブ23上に藁屑等が付着し易くなる。よって、前述の清掃部材80を設けるとともに、受網15における清掃部材80の上方部位のみ他の部位よりも孔の目合いを大きくする、つまり図示形態の場合は受網15の孔の目合いを受網15の前側に位置する孔151a,152aよりも後側に位置する孔151b〜151d,152b〜152dを大きくするのが好ましい。これにより、受網15の孔の目合いの大きな部分から穀粒だけでなく藁屑等も通過し易くなるが、その通過位置下方には清掃部材80が設けられているため、第一シーブ23に対する藁屑等の付着を効果的に防止できる。   (B) As shown in FIG. 29, when the mesh size of the holes of the receiving net 15 is larger than the holes 151a and 152a located on the front side of the holes 151b to 151d and 152b to 152d located on the rear side of the receiving net 15, Although the passage efficiency of the threshing product 15 is increased and the recovery efficiency of the grains is increased, the passage of the reception screen 15 such as sawdust is also promoted, so that the sawdust and the like easily adhere to the first sheave 23. . Therefore, the above-described cleaning member 80 is provided, and only the portion above the cleaning member 80 in the receiving net 15 has a larger mesh size than the other portions, that is, in the illustrated embodiment, the mesh size of the hole in the receiving net 15 is increased. It is preferable to make the holes 151b to 151d and 152b to 152d located on the rear side larger than the holes 151a and 152a located on the front side of the receiving net 15. As a result, not only the grains but also the shavings and the like can easily pass from the portion having a large mesh of holes in the receiving net 15. However, since the cleaning member 80 is provided below the passing position, the first sheave 23 is provided. It is possible to effectively prevent adhesion of sawdust etc.

なお、受網15の孔の目合いを大きくするとしても、本実施形態の受網15のように内周面に周方向に沿う仕切り金15dが立設している場合は、仕切り金15d直前部の孔151c,152cの目合いは大きくせず、相対的に小さくする方が好ましい。仕切り金15d直前部は扱歯10bの圧力が掛かり易く、脱穀率が高いため、この部分における受網15の孔151c,152cの目合いを大きくすると脱穀率が低下するだけでなく、藁屑等の受網15通過量が局所集中するおそれがある。   Even if the mesh size of the holes of the receiving net 15 is increased, when the partition metal 15d extending in the circumferential direction is erected on the inner peripheral surface as in the receiving network 15 of the present embodiment, immediately before the partition metal 15d. It is preferable to make the meshes of the holes 151c and 152c smaller, rather than making them relatively large. The portion immediately before the partition 15d is easily subjected to the pressure of the tooth handle 10b, and the threshing rate is high. Therefore, increasing the mesh of the holes 151c and 152c of the receiving net 15 in this portion not only lowers the threshing rate but also swarf etc. There is a possibility that the amount of passage through the receiving network 15 is locally concentrated.

また、本実施形態のように、二番処理室40の扱胴10側の側部上方が開口しており、その開口部が受網15の側部下方に位置し、受網15の側部から通過する脱穀処理物が二番処理室40に供給される構造となっている場合は、図27〜図29に詳細に示すように、受網15を、二番処理室40の扱胴側の側部上方に位置するアッパー部152と、これよりも下側に位置するロワー部151を連結して構成する分割構造とし、ロワー部151のみ仕切り金15d直前部の孔151cの目合いを大きくせず、相対的に小さくし、アッパー部152においては仕切り金15d直前部の孔152cか否かに関係なく、清掃部材80の上方部位の孔152b〜152dのみ他の部位の孔152aよりも目合いを大きくするとよい。つまり図示形態の場合は受網15の後側に位置する孔152b〜152dの目合いを前側に位置する孔152aの目合いより大きくするのが好ましい。ロワー部151からのろ過物は直接に第一シーブ23に供給されるため、このロワー部151の仕切り金15d直前部における孔151cの目合いを大きくしないことで1番物の枝梗割合が減少し、選別精度を良好に保つことができる。また、アッパー部152からのろ過物は二番処理室40に導かれ、揺動選別棚20前側に戻されるため、仕切り金15d直前部下方への藁屑等の集中供給は起こり難い。しかもこの場合、アッパー部152の孔の目合いは二番処理室40の搬送方向上流側に位置する孔152aの方が下流側に位置する孔152b〜152dよりも大きくなり、アッパー部152からの二番処理室40への脱穀処理物の供給量は搬送方向上流側の方が下流側よりも多くなるため、二番処理室40の処理経路を広範囲に利用して処理できるようになり、二番処理室40の処理能率を向上することができる。   Further, as in this embodiment, the upper side of the second processing chamber 40 on the side of the handling cylinder 10 is open, and the opening is located below the side of the receiving net 15. In the case where the threshing processed material passing from the second processing chamber 40 is supplied to the second processing chamber 40, the receiving net 15 is connected to the second processing chamber 40 on the cylinder side, as shown in detail in FIGS. The upper part 152 located above the side part of the upper part and the lower part 151 located below the lower part 151 are connected to form a divided structure. Only the lower part 151 has a larger size of the hole 151c immediately before the partition 15d. In the upper portion 152, only the holes 152b to 152d in the upper portion of the cleaning member 80 are larger than the holes 152a in other portions, regardless of whether or not the hole 152c is located immediately before the partition 15d. It is good to enlarge the match. That is, in the illustrated embodiment, it is preferable that the meshes of the holes 152b to 152d located on the rear side of the receiving net 15 are larger than the meshes of the holes 152a located on the front side. Since the filtrate from the lower part 151 is directly supplied to the first sheave 23, the ratio of the first branch is reduced by not increasing the size of the hole 151c in the part immediately before the partition 15d of the lower part 151. In addition, the sorting accuracy can be kept good. Further, since the filtrate from the upper portion 152 is guided to the second processing chamber 40 and returned to the front side of the swing sorting shelf 20, concentrated supply of sawdust and the like to the lower part immediately before the partition 15d hardly occurs. Moreover, in this case, the size of the holes in the upper portion 152 is larger in the holes 152a located on the upstream side in the transport direction of the second processing chamber 40 than the holes 152b to 152d located on the downstream side. Since the supply amount of the threshing product to the second processing chamber 40 is larger on the upstream side in the transport direction than on the downstream side, the processing path of the second processing chamber 40 can be processed over a wide range, The processing efficiency of the number processing chamber 40 can be improved.

(C)上記例は第一シーブのみ、清掃部材を設け、或いは上方に着脱自在としたが、シーブである限り、他のシーブについても同様の構成を適用することができる。
(制御装置)
前記機体フレーム1上には、機体1Aの左右傾斜角度を検出する左右傾斜センサ(請求項の「傾斜センサ」)1Bと、機体1Aの前後傾斜角度を検出する前後傾斜センサ(請求項の「傾斜センサ」)1Cを取り付ける。
(C) In the above example, only the first sheave is provided with a cleaning member or is detachable upward. However, as long as it is a sheave, the same configuration can be applied to other sheaves.
(Control device)
On the fuselage frame 1, a left / right tilt sensor (the “tilt sensor” in the claims) 1B for detecting the left / right tilt angle of the fuselage 1A and a forward / backward tilt sensor for detecting the front / back tilt angle of the fuselage 1A (inclination in the claims) Sensor ") 1C is installed.

図30に示すように、制御装置PUは、コントローラPUBに対して、その入力側に、この制御装置PUによるエンジン回転速度の制御を有効/無効に切り換える自動制御入り切りスイッチ200と、前記回転量検出装置96と、エンジンEの出力回転速度を検出するエンジン回転速度センサ201と、エンジンEの各気筒内へ噴射される燃料の量を検出する燃料噴射量センサ202と、前記左右傾斜センサ1Bと、前記前後傾斜センサ1Cを接続し、その出力側には、エンジンEの各気筒内へ噴射する燃料噴射量を調節する燃料噴射量調節用ソレノイド203と、前記第一シーブ23および第二シーブ24を開閉操作する電動モータ204と、前記風割66を回動調節する電動モータ205と、前記スクレーパ82を左右往復摺動させる駆動モータ85と、モニター206を接続して構成する。
(制御作動)
この構成により、揺動選別棚20上の処理物の量が増加した場合に、エンジンEの回転速度を自動的に増速することで、唐箕16からの選別風量が増加すると共に揺動選別棚20の揺動速度が増速し、揺動選別棚20上の処理物の後方移送能力が高まり、藁屑の排出が促進されて脱穀選別作業の能率が高まると共に、処理物中の穀粒の漏下が促進されて藁屑と共に排出されにくくなり、穀粒回収率を高めることができる。一方、揺動選別棚20上の処理物の量が減少した場合には、エンジンEの回転速度を自動的に減速することで、唐箕16からの選別風量が減少すると共に揺動選別棚20の揺動速度が減速し、揺動選別棚20上の処理物の後方移送能力が低下し、処理物中の穀粒の漏下が促進されて藁屑と共に排出されにくくなり、穀粒回収率を高めることができる。尚、エンジンEの増速上限の速度は、毎分2800回転程度の定格回転に設定するが、処理物の量が設定量を超えた場合には、エンジンEの回転速度をフルスロットル相当の回転速度まで増速する構成としてもよい。
また、処理物量検出センサ95の検出結果に基づいて第一シーブ23および第二シーブ24の開度を自動的に変更することで、揺動選別棚20上の処理物の量が増加した場合に第一シーブ23および第二シーブ24を開くことで、処理物中の穀粒の漏下が促進され、藁屑と共に排出されにくくなり、穀粒回収率を更に高めることができる。一方、揺動選別棚20上の処理物の量が減少した場合に第一シーブ23および第二シーブ24を閉じることで、藁屑の回収を抑え、選別精度を高めることができる。
また、処理物量検出センサ95の検出結果に基づいて風割66の傾斜姿勢を変更して選別風の送風方向を上下に変更することで、揺動選別棚20上の処理物の量が増加した場合に選別風の送風方向を揺動選別棚の揺動方向に沿う方向に倒すことで、この選別風によって処理物の後方移送能力を高め、脱穀作業の能率を高めることができる。また、揺動選別棚20上の処理物の量が減少した場合に選別風の送風方向を立ち上げることで、選別風による処理物の後方移送能力を低下させ、穀粒回収率を高めることができる。
また、処理物量検出センサ95の検出結果に基づいて選別風の送風量をも変更することで、脱穀作業の能率と穀粒回収率を更に高めることができる。
また、処理物量検出センサ95を、揺動選別棚20の前部の移送棚22上に上下動自在に配置したフロート97と、このフロート97の上下動位置を検出する回転量検出装置96から構成したので、移送棚22上の処理物の量を精度よく検出することができる。
As shown in FIG. 30, the control unit PU has an automatic control on / off switch 200 for switching the control of the engine rotation speed by the control unit PU to be valid / invalid with respect to the controller PUB, and the rotation amount detection. A device 96, an engine rotation speed sensor 201 for detecting the output rotation speed of the engine E, a fuel injection amount sensor 202 for detecting the amount of fuel injected into each cylinder of the engine E, the left / right tilt sensor 1B, The front / rear inclination sensor 1C is connected, and on its output side, a fuel injection amount adjusting solenoid 203 for adjusting the fuel injection amount injected into each cylinder of the engine E, the first sheave 23 and the second sheave 24 are provided. An electric motor 204 that opens and closes, an electric motor 205 that rotates and adjusts the air split 66, and a drive that slides the scraper 82 back and forth. A motor 85, is constructed by connecting the monitor 206.
(Control operation)
With this configuration, when the amount of processed material on the swing sorting shelf 20 increases, the rotational speed of the engine E is automatically increased, so that the amount of sorting air from the tang 16 increases and the swing sorting shelf. 20 swaying speed is increased, the backward transfer capability of the processed material on the oscillating sorting shelf 20 is enhanced, the discharge of swarf is promoted and the efficiency of the threshing sorting operation is increased, and the grains in the processed material are Leakage is promoted and it becomes difficult to be discharged together with sawdust, and the grain recovery rate can be increased. On the other hand, when the amount of the processed material on the swing sorting shelf 20 is reduced, the rotational speed of the engine E is automatically reduced to reduce the amount of sorting air from the tang 16 and the swing sorting shelf 20. The rocking speed is reduced, the ability to transfer the processed material on the rocking sorting shelf 20 is lowered, the leakage of the grain in the processed material is promoted, and it becomes difficult to be discharged together with the sawdust, and the grain recovery rate is reduced. Can be increased. The upper speed limit of the engine E is set at a rated speed of about 2800 revolutions per minute. However, if the amount of processed material exceeds the set amount, the rotational speed of the engine E is set to a speed equivalent to a full throttle. It is good also as a structure which increases to speed.
Further, when the amount of the processed material on the swing sorting shelf 20 is increased by automatically changing the opening degree of the first sheave 23 and the second sheave 24 based on the detection result of the processed material amount detection sensor 95. By opening the 1st sheave 23 and the 2nd sheave 24, the leakage of the grain in a processed material is accelerated | stimulated, it becomes difficult to discharge | emit with a sawdust, and a grain recovery rate can be raised further. On the other hand, by closing the first sheave 23 and the second sheave 24 when the amount of the processed material on the swing sorting shelf 20 is reduced, it is possible to suppress the collection of the sawdust and improve the sorting accuracy.
Further, the amount of the processed material on the swing sorting shelf 20 is increased by changing the inclination direction of the air split 66 based on the detection result of the processed material amount detection sensor 95 and changing the blowing direction of the selected air up and down. In this case, the sorting air can be moved in the direction along the swinging direction of the swinging sorting shelf, so that the rearward transfer ability of the processed material can be increased by the sorting wind and the efficiency of the threshing operation can be increased. Moreover, when the quantity of the processed material on the rocking sorting shelf 20 decreases, the rearward transfer capability of the processed material by the sorting air can be lowered and the grain recovery rate can be increased by raising the blowing direction of the sorting air. it can.
Moreover, the efficiency of a threshing operation | work and a grain collection | recovery rate can further be raised by changing also the ventilation volume of selection wind based on the detection result of the processed material amount detection sensor 95. FIG.
Further, the processing amount detection sensor 95 includes a float 97 which is arranged on the transfer shelf 22 in front of the swing sorting shelf 20 so as to be movable up and down, and a rotation amount detection device 96 which detects the vertical movement position of the float 97. Therefore, the amount of the processed material on the transfer shelf 22 can be detected with high accuracy.

また、左右傾斜センサ1Bまたは前後傾斜センサ1Cの少なくとも一方の傾斜センサによって機体1Aの傾斜が検出された場合に、駆動モータ85への作動出力を変更する。
即ち、機体1Aが右下がりに傾斜した場合には、スクレーパ82の左方向への摺動速度を増速させ、一方、機体1Aが左下がりに傾斜した場合には、スクレーパ82の右方向への摺動速度を増速させる。
これによって、揺動選別棚20上の処理物が左右一側に偏ることを防止でき、選別精度が高まる。
また、機体1Aが前下がりに傾斜した場合には、スクレーパ82の往復摺動速度を増速する。これによって、揺動選別棚20上の処理物の後方移送を促進し、選別作業の能率が高まる。一方、機体1Aが後下がりに傾斜した場合には、スクレーパ82の往復摺動速度を減速する。これによって、揺動選別棚20上の処理物の後方移送を抑制し、穀粒の排出を抑えて回収率を高めることができる。
Further, when the tilt of the body 1A is detected by at least one of the left / right tilt sensor 1B and the front / back tilt sensor 1C, the operation output to the drive motor 85 is changed.
That is, when the fuselage 1A is tilted to the right, the sliding speed of the scraper 82 is increased to the left. On the other hand, when the fuselage 1A is tilted to the left, the scraper 82 is moved to the right. Increase the sliding speed.
Thereby, it is possible to prevent the processed material on the swing sorting shelf 20 from being biased to the left and right sides, and the sorting accuracy is improved.
Further, when the body 1A is inclined forward and downward, the reciprocating sliding speed of the scraper 82 is increased. As a result, the rearward transfer of the processed material on the swing sorting shelf 20 is promoted, and the efficiency of the sorting work is increased. On the other hand, when the machine body 1A is inclined rearwardly, the reciprocating sliding speed of the scraper 82 is reduced. Thereby, the backward transfer of the processed material on the swing sorting shelf 20 can be suppressed, and the recovery rate can be increased by suppressing the discharge of the grains.

前記モニター206は3次元画像を表示可能であり、例えば、グレンタンク5内に貯留された穀粒の堆積高さを3次元表示することで、操縦者にわかりやすいものとすることができる。また、エンジンEのオーバーヒート状態などの異常状態をモニター206に三次元表示して警告するものとしてもよい。   The monitor 206 can display a three-dimensional image. For example, the three-dimensional display of the accumulated height of the grains stored in the Glen tank 5 can be made easy for the operator. Further, an abnormal state such as an overheat state of the engine E may be displayed on the monitor 206 in a three-dimensional manner to warn.
