Description

本発明は、脱穀装置の選別部に関し、特に、プレファンの省略、揺動本体の剛性強化、及びフィード板による揺動選別性能の向上が可能な、唐箕ファンとセカンドファンの風路構成に関する。   The present invention relates to a sorting unit of a threshing device, and more particularly, to an air passage configuration of a tang fan and a second fan capable of omitting a prefan, strengthening the rigidity of a rocking body, and improving rocking sorting performance by a feed plate.

従来より、コンバイン等の選別部の揺動本体では、揺動本体の前部が揺動可能に枢支され、揺動本体の後部がクランク軸や偏心軸等の揺動駆動軸に連結され、該揺動駆動軸を駆動させることにより、揺動本体が前後方向に揺動され、籾や藁屑等を後方へ送りながら「揺動選別」を行う。それと同時に、揺動本体の下方に配設した唐箕からの選別風を、揺動本体内と揺動本体下方に送風することにより「風選」が行われ、更に、チャフシーブ等の粗選別部やグレンシーブ等の精選別部においては、一番物や二番物や藁屑等に選別する「隙間選別」が行われていた。ところが、多条刈りのコンバインにおいては、一度に多量の脱粒が選別装置へ搬送されることがあり、この場合、選別処理が十分に行えなくなる。そこで、前記唐箕以外に、更に、もう一つの圧風ファン(以下「プレファン」とする)を唐箕前方に設け、該プレファンから、揺動本体上面沿いにも選別風を後方に送風し、唐箕からの選別風と併せて、揺動本体の上方・内部・下方に三つの選別風(以下、トリプルフロー)を形成することにより、藁屑等の選別効率を大きく向上させる技術が知られている。
特開平11−332369号公報
Conventionally, in a swinging body of a sorting unit such as a combine, the front part of the swinging body is pivotally supported so that the rear part of the swinging body is connected to a swinging drive shaft such as a crankshaft or an eccentric shaft, By driving the oscillating drive shaft, the oscillating main body is oscillated in the front-rear direction, and “oscillating selection” is performed while feeding slag, sawdust and the like backward. At the same time, “wind selection” is performed by blowing the sorting wind from the red pepper disposed below the swinging body into the swinging body and below the swinging body. In the fine sorting section such as Glensieve, “gap sorting” that sorts into the first thing, second thing, sawdust, etc. was performed. However, in a multi-row harvesting combine, a large amount of degranulation may be conveyed to the sorting device at a time, and in this case, the sorting process cannot be performed sufficiently. Therefore, in addition to the above-described Karatsu, another pressure wind fan (hereinafter referred to as “pre-fan”) is provided at the front of the Karatsu, and the pre-fan also blows a sorting wind rearward along the upper surface of the swinging body. A technology that greatly improves the sorting efficiency of sawdust etc. by forming three sorting winds (hereinafter referred to as triple flow) above, inside, and below the swinging body in combination with the sorting wind from Karatsu. Yes.
JP-A-11-332369

しかしながら、このようなプレファンを備えると、部品点数の増加、機体の重量化・大型化が避けられず、部品コストの増加、燃費や機体収納性の悪化を招き、更に、前記枢支軸等を設けた揺動本体前部下方にプレファンを設けるために、構造が複雑化し、組立性、メンテナンス性が悪化する、という問題があった。特に、選別部より選別した後の二番物を、二番コンベアから還元コンベアを介して枝梗処理装置へ送り、該枝梗処理装置により枝梗を取り除いた後に再び選別装置の選別開始部へ戻す二番物還元サイクルが採用されている場合には、処理効率を上げるために多量の二番物を枝梗処理装置に送り込むようにしており、そのため、該枝梗処理装置から、枝梗を除いた多量の二番物が揺動本体上に落下することになり、その衝撃に耐えうる更に高い剛性が、揺動本体に要求されるようになってきている。   However, with such a prefan, an increase in the number of parts, an increase in the weight and size of the fuselage are inevitable, resulting in an increase in component costs, a deterioration in fuel consumption and fuselage storage, and the pivot shaft etc. Since the prefan is provided below the front part of the swinging main body provided with the structure, there is a problem that the structure becomes complicated and the assembling property and the maintenance property are deteriorated. In particular, the second product after sorting from the sorting unit is sent from the second conveyor to the branch-branch processing device via the reduction conveyor, and after removing the branch-branch by the branch-branch processing device, it again goes to the sorting start unit of the sorting device. In the case where a returning second product reduction cycle is employed, a large amount of second product is sent to the branch-branch processing device in order to increase the processing efficiency. A large amount of the second object that has been removed falls on the swinging main body, and higher rigidity capable of withstanding the impact has been required for the swinging main body.

Processed material that gradually changes backward, flows along the upper surface of the coarse sorting section (33), rises toward the rear suction fan (25), is sucked, and leaks to the swing sorting device (27). The second sorting wind (74) is guided between the rough sorting section (33) and the fine sorting section (32), and then the wind sorting is performed on the coarse sorting section (33). It flows along the lower surface of the coarse sorting section (33), gradually rises and is sucked into the suction fan (25), and at the same time, the wet processed material staying on the fine sorting section (32) is sent backward, The processed material leaking through the coarse sorting section (33) is subjected to wind selection on the fine sorting section (32), and the third sorting wind (7 ) Is divided into an upper third upper sorting wind (75a) and a lower third lower sorting wind (75b) by the guide member (77) provided in the third air passage (63). Even without a prefan, it is possible to form three sorts of so-called triple flow on the coarse sorting section, between the coarse sorting section and the fine sorting section, and under the fine sorting section, reducing the number of parts. The weight and size of the machine can be reduced, and the structure of the front part of the sorting unit provided with the prefan is simplified, and the assembling and maintenance properties of the sorting unit are improved.

また、前記該第三上選別風(75a)は、該精選別部(32)の後部を経て、該粗選別部(33)の後部へと流れ、該吸引ファン(25)に吸い込まれ、該精選別部(32)を漏下する処理物の精選別部(32)下での風選を行い、前記第三下選別風(75b)は、該ガイド部材(77)により向きを変え、第三風路(63)内を後斜め下方に向かって吹き下ろし、第一流穀板(50)に衝突し、第一流穀板(50)上面から、該精選別部(32)の後部を経て、該吸引ファン(25)に吸い込まれるので、該第三下選別風75bは、第三風路63内を後斜め下方に向かって吹き下ろし、第一流穀板50に衝突して風向が後斜め上方に変わった後、第一流穀板50上面→グレンシーブ32後部→ストローラック76上面と流れ、最後は吸引ファン25に吸い込まれる。ここで、第一流穀板50後部に重なるようにして、後チャフシーブ78がグレンシーブ32後方に連設されており、該後チャフシーブ78の上を第三下選別風75bは流れていき、前記第三上選別風75aと一緒にグレンシーブ下での風選を行うと同時に、二番コンベア37に漏下してくる処理物の、後チャフシーブ78上での風選も可能としている。   The third upper sorting air (75a) flows through the rear part of the fine sorting part (32) to the rear part of the coarse sorting part (33) and is sucked into the suction fan (25). The air that has passed through the fine sorting section (32) is subjected to wind selection under the fine sorting section (32), and the third lower sorting wind (75b) is changed in direction by the guide member (77). Blow down the inside of the three air passages (63) obliquely downward, collide with the first flow cereal plate (50), from the upper surface of the first flow cereal plate (50), through the rear of the fine sorting unit (32), Since it is sucked into the suction fan (25), the third lower sorting wind 75b blows down in the third air passage 63 rearward and obliquely downward, collides with the first flow cereal plate 50, and the wind direction is obliquely upward rearward. After the change, the flow from the upper surface of the first cereal plate 50 to the rear portion of the grain sieve 32 to the upper surface of the strolac 76, and finally the suction flow. It is sucked into the emissions 25. Here, a rear chaff sheave 78 is connected to the rear of the grain sheave 32 so as to overlap the rear portion of the first flow grain plate 50, and the third lower sorting wind 75b flows on the rear chaff sheave 78, and the third While selecting the wind under the Glen sieve together with the upper sorting wind 75a, it is also possible to select the wind on the rear chaff sheave 78 of the processed material leaking to the second conveyor 37.

請求項2においては、請求項1記載の脱穀装置において、前記揺動選別装置(27)下方の前後途中位置には、左右方向に一番コンベア(36)と二番コンベア(37)とを平行して横設し、該一番コンベア(36)と二番コンベア(37)との間にセカンドファン(41)を設け、前記揺動選別装置(27)の後部に設けた一番コンベア(36)の後部の第一流穀板(50)の後方延長線上近傍で、精選別部(32)の後方に、予備上ガイド部材(94)を設け、該予備上ガイド部材(94)下部と、二番コンベア(37)の後面の第二流穀板(51)との間に予備風路(96)を形成し、該予備風路(96)上下略中央位置には、後斜め上方に傾斜して予備下ガイド部材(95)を横設し、該予備下ガイド部材(95)の上面と予備上ガイド部材(94)の下面とにより、上予備風路(96a)を形成し、該予備下ガイド部材(95)の下面と、前記第二流穀板(51)の上面とから下予備風路(96b)を形成し、該セカンドファン(41)の吐出口(91)から後方に噴き出した選別風は、該予備選別風93として前記上予備風路96a内を流れ、その大部分は排出風(93a)として吸引ファン(25)に吸い込まれて機外に排出されるが、一部は、戻り風(93b)として予備下ガイド部材(95)の後端から下予備風路(96b)内に流れ込むので、セカンドファン41の前記吐出口91から後方に噴き出した選別風は、予備選別風93として前記上予備風路96a内を流れていき、その大部分は排出風93aとして吸引ファン25に吸い込まれて機外に排出されるが、一部は、戻り風93bとして予備下ガイド部材95後端から下予備風路96b内に流れ込む。これは、上予備風路96a内を高速で流れ(正圧)る予備選別風93による吸引作用によって、下予備風路96b内の空気(負圧)が予備下ガイド部材95前端から上予備風路96a内に吸い込まれるためであり、前記戻り風93bは、予備下ガイド部材95を中心とした渦流を形成するようになる。そして、この渦流は、第二流穀板51上の二番物の流下を促進するのである。 In Claim 2, in the threshing device according to Claim 1, the first conveyor (36) and the second conveyor (37) are parallel in the left-right direction at a position in the front-rear direction below the swing sorting device (27). The second conveyor (41) is provided between the first conveyor (36) and the second conveyor (37), and the first conveyor (36 ) A rear upper guide member (94) is provided behind the fine sorting portion (32) in the vicinity of the rear extension line of the rear first flow grain plate (50), and a lower portion of the preliminary upper guide member (94); A preliminary air passage (96) is formed between the rear conveyor (37) and the second cereal plate (51) on the rear surface, and the preliminary air passage (96) is inclined obliquely upward and rearward at a substantially central position in the vertical direction. The auxiliary lower guide member (95) is installed horizontally, and the upper surface of the auxiliary lower guide member (95) is connected to the auxiliary upper guide member (95). The upper preliminary air passage (96a) is formed by the lower surface of the main member (94), and the lower preliminary air passage is formed from the lower surface of the preliminary lower guide member (95) and the upper surface of the second flown cereal plate (51). (96b), and the sorting air blown rearward from the discharge port (91) of the second fan (41) flows in the upper preliminary air passage 96a as the preliminary sorting air 93, most of which is discharged air (93a) is sucked into the suction fan (25) and discharged out of the apparatus, but a part of the return air (93b) from the rear end of the preliminary lower guide member (95) to the lower preliminary wind path (96b) Therefore, the sorting air blown backward from the discharge port 91 of the second fan 41 flows in the upper preliminary air passage 96a as the preliminary sorting air 93, and most of the air flows into the suction fan 25 as the exhaust air 93a. Inhaled and discharged outside the machine Some flows into the lower pre-air passage 96b from preliminary lower guide member 95 the rear end as the return air 93 b. This is because the air (negative pressure) in the lower preliminary air passage 96b flows from the front end of the auxiliary lower guide member 95 to the upper auxiliary air by the suction action of the preliminary sorting air 93 that flows (positive pressure) in the upper auxiliary air passage 96a at high speed. This is because the return air 93 b forms a vortex centered on the preliminary lower guide member 95. And this eddy current accelerates | stimulates the flow of the 2nd thing on the 2nd flow grain board 51. FIG.

The guide body 66a is formed along the bottom plate 46b of the swinging main body 46, and the rear end of the guide body 66a is connected to the front end of the rear feed plate 31.

このように、上下のガイド部材64・66とも、揺動本体46の左右側板46a・46a間を強固に連結しているため、揺動本体46の剛性が強化され、特に、上ガイド部材64は、前フィード板30の下面に当接固定されて略T字構造を構成しており、前フィード板30の支持力を高めている。   Thus, since the upper and lower guide members 64 and 66 are firmly connected between the left and right side plates 46a and 46a of the swing body 46, the rigidity of the swing body 46 is enhanced. The front feed plate 30 is abutted and fixed to the lower surface to form a substantially T-shaped structure, and the support force of the front feed plate 30 is enhanced.

すなわち、ガイド部材には上ガイド部材64を設け、該上ガイド部材64の一端は、前フィード板30下面に固定し、他端は、前斜め下方に延設するので、上ガイド部材64は、唐箕26からの選別風の風向ガイドとして以外に、揺動本体46の両側板46a・46aの補強部材としての機能も有しており、揺動本体の剛性強化が図れ、特に、T字構造により、前記枝梗処理装置52から落下する多量の二番物による衝撃にも十分耐えることができる。   That is, the upper guide member 64 is provided on the guide member, and one end of the upper guide member 64 is fixed to the lower surface of the front feed plate 30 and the other end extends obliquely downward in the front direction. Besides serving as a wind direction guide for the sorting wind from the tang 26, it also has a function as a reinforcing member for both side plates 46a, 46a of the swing body 46, so that the rigidity of the swing body can be enhanced. Further, it can sufficiently withstand the impact caused by a large amount of the second object falling from the branch-branch processing device 52.

また、ガイド部材には下ガイド部材66を設け、該下ガイド部材66は、前記粗選別部であるチャフシーブ33の前部下方に配置した後フィード板31の前端から前方に延設するので、揺動本体46下部の両側板46a・46a間の補強部材として機能し、揺動本体46の剛性強化を図ることができる。   Further, the guide member is provided with a lower guide member 66, and the lower guide member 66 extends forward from the front end of the rear feed plate 31 disposed below the front portion of the chaff sheave 33 which is the rough sorting portion. It functions as a reinforcing member between the side plates 46a and 46a at the lower part of the moving body 46, and the rigidity of the swinging body 46 can be enhanced.

ここで、揺動本体46前部の底板46bからは側面視略V字状の支持部材69が垂設され、該支持部材69の内側溝部に前記軸47が固定されると共に、該軸47の外側端部は、揺動本体46の左側の側板46aに固設された補強板70によって支持されている。更に、枢支軸47の最外端にはコロ71が回動自在に外嵌され、該コロ71は、機枠35の両側板に固設された一対の摺動ガイド72・72間に内挿されている。   Here, a substantially V-shaped support member 69 in a side view is suspended from the bottom plate 46 b at the front of the swinging body 46, and the shaft 47 is fixed to the inner groove portion of the support member 69. The outer end portion is supported by a reinforcing plate 70 fixed to the left side plate 46 a of the swing body 46. Further, a roller 71 is rotatably fitted on the outermost end of the pivot shaft 47, and the roller 71 is interposed between a pair of sliding guides 72 and 72 fixed to both side plates of the machine frame 35. It is inserted.

このような構成において、前記揺動装置29が駆動すると、揺動本体46を支持するコロ71が、前記摺動ガイド72・72の内側面に沿って、前斜め下方から後斜め上方に向かって往復動し、揺動選別装置27全体を上下動と前後動を合成した揺動を行わせることができ、揺動選別性能の一層の向上を図るようにしている。なお、右側の側板46aにも、同様にして軸47が支持されており、揺動本体46が左右の軸47・47上のコロ71により支持された上で、揺動されるようにしている。   In such a configuration, when the swinging device 29 is driven, the rollers 71 that support the swinging main body 46 are moved from the front obliquely downward to the rear obliquely upward along the inner surfaces of the sliding guides 72 and 72. By reciprocating, the entire swing sorting device 27 can be swung by combining up and down motion and back and forth motion, so that the swing sorting performance can be further improved. Similarly, the right side plate 46a also supports the shaft 47 so that the swinging main body 46 is swung after being supported by the rollers 71 on the left and right shafts 47 and 47. .

そして、前記補強板70から後方には、側板46aに複数の取付板65bが固設され、該取付板65bを介して、中ガイド部材65のガイド体65aが横架・固定されている。該ガイド体65aの前端は、補強板70に支持された枢支軸47近傍まで延設されると共に、ガイド体65aの後端は、チャフシーブ33の前端直上まで延設して固定されている。   A plurality of mounting plates 65b are fixed to the side plate 46a behind the reinforcing plate 70, and the guide body 65a of the middle guide member 65 is horizontally mounted and fixed via the mounting plate 65b. The front end of the guide body 65 a extends to the vicinity of the pivot shaft 47 supported by the reinforcing plate 70, and the rear end of the guide body 65 a extends to the position just above the front end of the chaff sheave 33 and is fixed.

このように、中ガイド部材65は、枢支軸47近傍まで延設して左右の補強板70・70あるいは側板46a・46a間を強固に連結し、揺動運動で過大な応力のかかる枢支軸47周辺の剛性が強化される。   As described above, the middle guide member 65 extends to the vicinity of the pivot shaft 47 to firmly connect the left and right reinforcing plates 70 and 70 or the side plates 46a and 46a, and is pivotally applied with excessive stress by the swinging motion. The rigidity around the shaft 47 is enhanced.

すなわち、ガイド部材には中ガイド部材65を設け、該中ガイド部材65の一端は、前記揺動本体46前下部に設けた揺動用の枢支軸47に近設し、他端は、前記粗選別部であるチャフシーブ33の前端直上まで後斜め上方に延設するので、唐箕26からの選別風の風向ガイドとして以外に、揺動本体46の両側板46a・46aの補強部材としての機能も有し、特に、最も部品破損等の多い枢支軸47周囲の剛性強化を図ることができ、揺動選別装置27の部品交換頻度を少なくしてランニングコストの低減やメンテナンス作業の軽減を図ることができるのである。   That is, the guide member is provided with an intermediate guide member 65, one end of the intermediate guide member 65 is provided close to the pivot shaft 47 provided at the front lower part of the swing body 46, and the other end is provided with the rough guide member 65. Since it extends rearward and obliquely upward to just above the front end of the chaff sheave 33 which is a sorting part, it also functions as a reinforcing member for both side plates 46a and 46a of the swinging body 46, in addition to a wind direction guide for the sorting wind from the tang 26 In particular, the rigidity around the pivot shaft 47 that causes the most damage to the parts can be enhanced, and the replacement frequency of the swing sorting device 27 can be reduced to reduce the running cost and the maintenance work. It can be done.

次に、以上のように配置されたガイド部材64・65・66等による風路構成について、図4、図7、図8により説明する。前記唐箕ケース60においては、前記上ガイド部材64下面から該上ガイド部材64後端に連結された前フィード板30後部下面にかけて形成されるガイド面と、前記中ガイド部材65の上面とから、第一風路61が形成される。さらに、該中ガイド部材65の下面と、前記上仕切板58前部上面から下ガイド部材66上面にかけて形成されるガイド面とから、第二風路62が形成される。そして、前記後開口部68において、前記上仕切板58下面と下仕切板59上面とから、第三風路63が形成されている。   Next, the air path configuration by the guide members 64, 65, 66 and the like arranged as described above will be described with reference to FIGS. 4, 7, and 8.

In the rear opening 68, a third air path 63 is formed from the lower surface of the upper partition plate 58 and the upper surface of the lower partition plate 59.

このような構成において、唐箕26の前記上開口部67から吹き上げた選別風は、前記第一風路61と第二風路62とに流れ込み、そのうち第一風路61に吹き込んだ選別風は、第一選別風73として、風向を上方から後方へ徐々に変えながらチャフシーブ33に向かって流れていく。そして、該チャフシーブ33上面に沿って流れながら、後方の吸引ファン25に向かって次第に上昇して吸い込まれていき、前記各受網20・24から揺動選別装置27へ漏下する処理物の、チャフシーブ33上での風選を可能としている。   In such a configuration, the sorting air blown from the upper opening 67 of the tang 26 flows into the first air passage 61 and the second air passage 62, and the sorting air blown into the first air passage 61 is As the first selection air 73, the air flows toward the chaff sheave 33 while gradually changing the air direction from the upper side to the rear side. Then, while flowing along the upper surface of the chaff sheave 33, the processed material gradually rising and sucked toward the rear suction fan 25 and leaking from the receiving nets 20, 24 to the swing sorting device 27, Wind selection on the chaff sheave 33 is possible.

そして、前記第二風路62に吹き込んだ選別風は、第二選別風74として、チャフシーブ33とグレンシーブ32との間に導かれていき、その後、チャフシーブ33下面に沿って流れながら、チャフシーブ33内を次第に上昇して吸引ファン25に吸い込まれていき、後フィード板31上に滞留する湿った処理物を後方に送り出すと同時に、チャフシーブ33を漏下してくる処理物の、グレンシーブ32上での風選を可能としている。   Then, the sorting air blown into the second air passage 62 is guided as a second sorting air 74 between the chaff sheave 33 and the Glen sheave 32, and then flows along the lower surface of the chaff sheave 33, while in the chaff sheave 33. Is gradually sucked into the suction fan 25, and the wet processed material staying on the rear feed plate 31 is sent backward, and at the same time, the processed material leaking through the chaff sheave 33 is transferred to the Glen sieve 32. Wind selection is possible.

また、唐箕26の前記後開口部68から後方に吹き出した選別風は、第三選別風75として前記第三風路63内に流れ込む。該第三選別風75は、第三風路63内に角度位置調整可能に設けた調整ガイド部材77によって、上方の第三上選別風75aと下方の第三下選別風75bとに分流され、このうち第三上選別風75aは、第三風路63→グレンシーブ32後部→チャフシーブ33後部と流れ、最後は吸引ファン25に吸い込まれ、グレンシーブ32を漏下する処理物の、グレンシーブ32下での風選を可能としている。   Further, the sorting air blown backward from the rear opening 68 of the tang 26 flows into the third air passage 63 as the third sorting air 75. The third selection air 75 is divided into an upper third upper selection air 75a and a lower third lower selection air 75b by an adjustment guide member 77 provided in the third air passage 63 so as to be capable of adjusting the angular position. Among them, the third upper sorting air 75a flows from the third air passage 63 → the rear portion of the Glen sheave 32 → the rear portion of the chaff sheave 33, and is finally sucked into the suction fan 25, and the processed material that leaks the Glen sheave 32 under the Glen sheave 32. Wind selection is possible.

第三下選別風75bは、第三風路63内を後斜め下方に向かって吹き下ろし、第一流穀板50に衝突して風向が後斜め上方に変わった後、第一流穀板50上面→グレンシーブ32後部→ストローラック76上面と流れ、最後は吸引ファン25に吸い込まれる。ここで、第一流穀板50後部に重なるようにして、後チャフシーブ78がグレンシーブ32後方に連設されており、該後チャフシーブ78の上を第三下選別風75bは流れていき、前記第三上選別風75aと一緒にグレンシーブ下での風選を行うと同時に、二番コンベア37に漏下してくる処理物の、後チャフシーブ78上での風選も可能としている。   The third lower sorting wind 75b blows down in the third air passage 63 rearward and obliquely downward, collides with the first flow cereal plate 50 and changes the wind direction obliquely upward, and then the upper surface of the first flow cereal plate 50 → It flows from the rear part of the grain sieve 32 to the upper surface of the Strollac 76 and finally sucked into the suction fan 25. Here, a rear chaff sheave 78 is connected to the rear of the grain sheave 32 so as to overlap the rear portion of the first flow grain plate 50, and the third lower sorting wind 75b flows on the rear chaff sheave 78, and the third While selecting the wind under the Glen sieve together with the upper sorting wind 75a, it is also possible to select the wind on the rear chaff sheave 78 of the processed material leaking to the second conveyor 37.

すなわち、選別部17に、脱穀部10の受網より漏下する処理物を受けて後方に移送する前フィード板30と、該前フィード板30からの処理物を選別する粗選別部であるチャフシーブ33と、該チャフシーブ33から漏下する処理物を更に選別する精選別部であるグレンシーブ32とを備えると共に、前記前フィード板30下方には、揺動本体46に選別風を送風する唐箕26を配置した脱穀装置19において、該唐箕26周囲を覆う唐箕ケース60に、前記チャフシーブ33上面に沿って第一選別風73を後方に送風する第一風路61と、チャフシーブ33とグレンシーブ32との隙間に沿って第二選別風74を後方に送風する第二風路62と、前記グレンシーブ32の下方に向かって第三選別風75を送風する第三風路63とを形成したので、プレファンを設けずとも、粗選別部の上、粗選別部と精選別部との間、精選別部の下に三つの選別風、いわゆるトリプルフローを形成することができ、部品点数の削減、機体の軽量化・小型化を図ることができ、更に、プレファンを設けていた選別部17前部の構造が簡素化され、選別部17の組立性、メンテナンス性も向上する。   That is, the sorting unit 17 receives a processed product leaked from the receiving net of the threshing unit 10 and transfers it to the rear, and a chaff sieve that is a coarse sorting unit that sorts the processed product from the front feed plate 30. 33 and a grain sheave 32 that is a fine sorting portion for further sorting the processed material leaking from the chaff sheave 33, and a tang 26 that blows sorting air to the rocking body 46 is provided below the front feed plate 30. In the arranged threshing device 19, a gap between the first air passage 61 for blowing the first selected air 73 rearward along the upper surface of the chaff sheave 33, and the chaff sheave 33 and the glen sieve 32, in the red pepper case 60 that covers the periphery of the tang 26. A second air passage 62 for blowing the second sorted air 74 rearward along with the third air passage 63 and a third air passage 63 for blowing the third sorted air 75 toward the lower side of the grain sieve 32 are formed. Therefore, without providing a prefan, it is possible to form three sorting winds, so-called triple flow, on the coarse sorting section, between the coarse sorting section and the fine sorting section, and under the fine sorting section. Reduction, weight reduction and downsizing of the machine body can be achieved, and the structure of the front part of the sorting unit 17 provided with the prefan is simplified, and the assembling property and maintainability of the sorting unit 17 are improved.

そして、揺動本体46を形成する左右側板46a・46a間は、前記第一風路乃至第三風路61・62・63を形成するガイド部材64・65・66を横設して連結するので、ガイド部材64・65・66により、揺動本体46が補強されて剛性強化が図れ、揺動選別効率が向上すると共に、簡単なガイド部材の取付けだけでトリプルフローを達成することができ、一層の製造コスト低減を図ることができるのである。   And between the left and right side plates 46a, 46a forming the swing body 46, the guide members 64, 65, 66 forming the first to third air passages 61, 62, 63 are laterally connected. The guide members 64, 65, and 66 reinforce the swing body 46 to enhance the rigidity, improve the swing sorting efficiency, and achieve a triple flow by simply mounting the guide member. The manufacturing cost can be reduced.

また、選別部17には、選別後の二番物を脱穀部10前部に還元搬送する還元コンベア40を設け、該還元コンベア40の終端には、二番処理胴53を備える枝梗処理装置52を設けるので、枝梗付着粒を減少して脱穀効率が向上する。しかも、多量に籾を枝梗処理した場合でも、籾はガイド部材64・65・66で補強された剛性の高い揺動本体46上に落下するため、前フィード板30等が落下の衝撃で変形したり、揺動が不安定になったりすることがなく、後方への籾の搬送が円滑に行われ、効率的な二番物還元サイクルが可能となる。   Further, the sorting unit 17 is provided with a reduction conveyor 40 that reduces and conveys the second product after sorting to the front part of the threshing unit 10, and a branch branch processing apparatus including a second processing cylinder 53 at the end of the reduction conveyor 40. Since 52 is provided, the threshing efficiency is improved by reducing the branch-attached grains. In addition, even when a large amount of the culm is treated with the pedicle, the culm drops on the rigid rocking body 46 reinforced by the guide members 64, 65, and 66, so that the front feed plate 30 is deformed by the impact of the drop. And the rocking is not unstable, and the soot is smoothly conveyed to the rear, enabling an efficient second product reduction cycle.

次に、前記セカンドファン41の取付構成について、図4、図7、図9により説明する。図4、図9に示すように、セカンドファン41は、左右に軸芯を有する回動軸83と、該回動軸83より半径方向に放射状に突設する羽根体84・84・・・より構成され、セカンドファンの回動軸83は、前記機枠35側部に固設した枢結プレート79により支持されている。そして、このセカンドファン41は、回転周囲を覆うファンケース80内に内装され、該ファンケース80には、背面視略矩形状の吐出口91が開口されている。   Next, the mounting structure of the second fan 41 will be described with reference to FIGS. 4, 7, and 9. As shown in FIGS. 4 and 9, the second fan 41 includes a rotating shaft 83 having axial centers on the left and right sides, and blade bodies 84, 84... Projecting radially from the rotating shaft 83 in the radial direction. The second fan rotating shaft 83 is supported by a pivoting plate 79 fixed to the side of the machine casing 35. The second fan 41 is housed in a fan case 80 that covers the periphery of the rotation. The fan case 80 has a discharge port 91 that is substantially rectangular in a rear view.

前記機枠35内で揺動本体46の下方には選別樋97が配設され、該選別樋97の前部は、前記唐箕ケース60により構成されている。そして、該唐箕ケース60よりも後方の選別樋97には、凹部97a・97bが設けられ、該凹部97a・97bに、それぞれ前記一番コンベア36・二番コンベア37が内設されている。更に、該一番コンベア36と二番コンベア37との間の選別樋97には取付口97cが開口され、該取付口97cに、前記吐出口91が内挿されている。また、選別樋97には、位置89と位置90との間を移動可能な側面視コ字状のケースガイド85が設けられ、該ケースガイド85の開放部85aには、前記ファンケース80の吐出口91に設けた摺動部80aが内挿できるようにしている。   A sorting bar 97 is disposed below the swinging body 46 in the machine frame 35, and the front part of the sorting bar 97 is constituted by the Kara case 60. Further, the sorting basket 97 behind the Karatsu case 60 is provided with recesses 97a and 97b, and the first conveyor 36 and the second conveyor 37 are provided in the recesses 97a and 97b, respectively. Further, an attachment port 97c is opened in the sorting basket 97 between the first conveyor 36 and the second conveyor 37, and the discharge port 91 is inserted into the attachment port 97c. Further, the sorting rod 97 is provided with a case guide 85 having a U-shaped side view that can move between a position 89 and a position 90, and a discharge portion of the fan case 80 is disposed in an opening 85 a of the case guide 85. A sliding portion 80a provided at the outlet 91 can be inserted.

このような構成において、ファンケース80を取り付ける際には、まず、ケースガイド85を位置89までスライドした上で、該ケースガイド85の開放部85aに前記摺動部80aを側方より挿入した後、ケースガイド85にガイドさせながら、ファンケース80を機体内側に向かって押し込んでいく。そして、全部押し込んだ後に、ケースガイド85を位置89から位置90まで戻した上で、ファンケース80を、吐出口91の外周が取付口97cに当接するまで、回動軸83と同軸上を中心に時計回り(左側面視)に回動し、その後、ファンケース80を、複数のボルト86によって選別樋97に固定する。   In such a configuration, when the fan case 80 is attached, the case guide 85 is first slid to the position 89 and then the sliding portion 80a is inserted into the open portion 85a of the case guide 85 from the side. The fan case 80 is pushed toward the inside of the machine body while being guided by the case guide 85. Then, after all the pushing-in, the case guide 85 is returned from the position 89 to the position 90, and the fan case 80 is centered on the same axis as the rotation shaft 83 until the outer periphery of the discharge port 91 contacts the mounting port 97c. Then, the fan case 80 is fixed to the sorting rod 97 with a plurality of bolts 86.

このため、吐出口91は、取付口97cよりも必ず内側に配置されることとなり、吐出口91からは、セカンドファン41からの予備選別風93が、取付口97cに邪魔されることなく後方に噴き出す。従って、塵埃が、唐箕26から選別風73・74・75と一緒に送られてきたり、上方の精選別部であるチャフシーブ33から漏下しても、予備選別風93の風圧で吐出口91近傍に固着されることなく、そのまま予備選別風93にのって吸引ファン25に吸い上げられて機外へ排出されるため、選別風の流れを乱すような固着物が発生しない。   For this reason, the discharge port 91 is always arranged inside the attachment port 97c, and the preliminary sorting air 93 from the second fan 41 is rearward from the discharge port 91 without being obstructed by the attachment port 97c. Erupt. Accordingly, even if dust is sent together with the sorting air 73, 74, 75 from the tang 26 or leaks from the chaff sheave 33 which is the upper precision sorting section, the vicinity of the discharge port 91 is caused by the wind pressure of the preliminary sorting air 93. In this case, the preliminarily sorted air 93 is sucked up by the suction fan 25 and discharged to the outside of the apparatus, so that no fixed matter that disturbs the flow of the sorted air is generated.

すなわち、揺動本体46下方の選別樋97には、前から順に、選別風を送風する唐箕26と、揺動本体46から漏下する一番物を穀粒タンク13に搬送する一番コンベア36と、二番物を還元コンベア40を介して脱穀部10前部に還元搬送する二番コンベア37とを横設し、該二番コンベア37と前記一番コンベア36との間にはセカンドファン41を設けた脱穀装置19において、該セカンドファン41を収納するファンケース80には、前記選別風の風量を補う予備選別風93を選別部17後部に噴き出す吐出口91を設け、該吐出口91は、前記選別樋97に設けた取付口97cに内挿して取付可能な構成としたので、予備選別風93の噴き出し方向には、風の流れを乱すような障害物がなく、固着しやすい塵埃もセカンドファン41からの予備選別風93にのって機外へ容易に排出されるため、該予備選別風93の風路内への固着物付着による渦流の発生を防止し、風選効率の向上を図ることができる。   That is, the sorting basket 97 below the swinging main body 46 has, in order from the front, the red pepper 26 that blows the sorting wind, and the first conveyor 36 that conveys the first thing leaking from the swinging main body 46 to the grain tank 13. And a second conveyor 37 for reducing and transporting the second product to the front part of the threshing section 10 via the reduction conveyor 40, and a second fan 41 between the second conveyor 37 and the first conveyor 36. In the threshing device 19 provided with the above, the fan case 80 that houses the second fan 41 is provided with a discharge port 91 that blows out a preliminary selection air 93 that supplements the air volume of the selection air to the rear part of the selection unit 17. Since the configuration is such that it can be installed by being inserted into the mounting opening 97c provided in the sorting rod 97, there is no obstacle that disturbs the flow of the wind in the blowing direction of the preliminary sorting wind 93, and dust that is easily fixed is also present. Second fan 4 Is easily discharged out of the machine along the pre-sorted air 93, so that the generation of eddy currents due to sticking matter adhering to the air path of the pre-sorted air 93 is prevented and the wind-selecting efficiency is improved. Can do.

さらに、前記吐出口91は、選別樋97の取付口97cに着脱自在な構成とするので、セカンドファン41が不要な場合には取り外すことで、同じ選別樋97を用いて、セカンドファン41のない選別部17に容易に変更することができ、セカンドファンの有無に応じて選別樋を作り分ける必要がなくなり、部品コストの大幅な低減を図ることができるのである。   Further, since the discharge port 91 is configured to be detachable from the attachment port 97c of the sorting rod 97, the second fan 41 can be removed when the second fan 41 is unnecessary, so that the second fan 41 can be removed using the same sorting rod 97. The sorting unit 17 can be easily changed, and it is not necessary to make a sorting basket separately according to the presence or absence of the second fan, so that the cost of parts can be greatly reduced.

次に、セカンドファン41の選別風の風路構成について、図4、図7、図9により説明する。セカンドファン41の上方で、前記揺動本体46の側板46aから垂設された取付板81には、前記第一流穀板50上部が固設され、該第一流穀板50の下部は、一番コンベア36を内設した凹部97aに向かって前斜め下方に延設されている。同様に、前記揺動装置29上方の側板46aからも取付板82が垂設され、該取付板82には第二流穀板51上部が固設され、該第二流穀板51の下部は、二番コンベア37を内設した凹部97bに向かって前斜め下方に延設されている。   Next, the air path configuration of the selection air of the second fan 41 will be described with reference to FIGS. 4, 7, and 9. The upper part of the first cereal plate 50 is fixed to the mounting plate 81 suspended from the side plate 46a of the swinging body 46 above the second fan 41, and the lower part of the first cereal plate 50 is Extending obliquely downward to the front toward the recess 97a in which the conveyor 36 is provided. Similarly, a mounting plate 82 is also suspended from the side plate 46a above the swinging device 29, and the upper part of the second flown cereal plate 51 is fixed to the mounting plate 82, and the lower part of the second flown cereal plate 51 is The second conveyor 37 is extended obliquely forward and downward toward the recess 97b.

さらに、前記後チャフシーブ78と平行に予備上ガイド部材94が配設され、該予備上ガイド部材94の下面と、前記第二流穀板51の上面とから、予備風路96が形成されている。更に、該予備風路96上下略中央位置には、後斜め上方に傾斜して予備下ガイド部材95が横設されており、該予備下ガイド部材95の上面と予備上ガイド部材94の下面とから上予備風路96aが形成され、予備下ガイド部材95の下面と第二流穀板51の上面とから下予備風路96bが形成されている。   Further, a preliminary upper guide member 94 is disposed in parallel with the rear chaff sheave 78, and a preliminary air passage 96 is formed from the lower surface of the preliminary upper guide member 94 and the upper surface of the second cereal plate 51. . Further, a preliminary lower guide member 95 is provided at a substantially central position in the vertical direction of the preliminary air passage 96 so as to incline rearward and obliquely upward. The upper surface of the preliminary lower guide member 95 and the lower surface of the preliminary upper guide member 94 The upper preliminary wind path 96a is formed from the lower surface of the preliminary lower guide member 95 and the upper surface of the second flow grain board 51.

このような構成において、セカンドファン41の前記吐出口91から後方に噴き出した選別風は、予備選別風93として前記上予備風路96a内を流れていき、その大部分は排出風93aとして吸引ファン25に吸い込まれて機外に排出されるが、一部は、戻り風93bとして予備下ガイド部材95後端から下予備風路96b内に流れ込む。これは、上予備風路96a内を高速で流れ(正圧)る予備選別風93による吸引作用によって、下予備風路96b内の空気(負圧)が予備下ガイド部材95前端から上予備風路96a内に吸い込まれるためであり、前記戻り風93bは、予備下ガイド部材95を中心とした渦流を形成するようになる。そして、この渦流は、第二流穀板51上の二番物の流下を促進するのである。   In such a configuration, the sorting air blown backward from the discharge port 91 of the second fan 41 flows in the upper preliminary air passage 96a as the preliminary sorting air 93, and most of the suction air is discharged as the suction air 93a. However, a part of the air flows into the lower auxiliary air passage 96b from the rear end of the auxiliary lower guide member 95 as the return air 93b. This is because the air (negative pressure) in the lower preliminary air passage 96b flows from the front end of the auxiliary lower guide member 95 to the upper auxiliary air by the suction action of the preliminary sorting air 93 that flows (positive pressure) in the upper auxiliary air passage 96a at high speed. This is because the return air 93 b forms a vortex centered on the preliminary lower guide member 95. And this eddy current accelerates | stimulates the flow of the 2nd thing on the 2nd flow grain board 51. FIG.

すなわち、脱穀装置19に設けた揺動選別装置27の前部下方に唐箕26を配置し、該唐箕26後方には、前から順に、一番コンベア36、セカンドファン41、二番コンベア37を横設し、揺動選別装置27の後端部近傍には機内の塵を排出する吸引ファン25を備えると共に、前記一番コンベア36と二番コンベア37の後上方には、それぞれ第一流穀板50と第二流穀板51を配設した脱穀装置19において、前記セカンドファン41から後斜め上方に送風される予備選別風93は、そのまま前記吸引ファン25に藁屑等と一緒に吸引される排出風93aと、前記二番コンベア37に二番物等と一緒に逆戻りする戻り風93bとから構成したので、二番コンベア37への二番物等の流下を促進し、揺動選別効率全体を向上させることができる。   In other words, a red pepper 26 is arranged below the front part of the swing sorting device 27 provided in the threshing device 19, and the first conveyor 36, the second fan 41, and the second conveyor 37 are placed in the rear side of the red pepper 26 in order from the front. And a suction fan 25 for discharging dust in the machine in the vicinity of the rear end of the swing sorting device 27, and a first cereal plate 50 on the upper rear side of the first conveyor 36 and the second conveyor 37, respectively. In the threshing apparatus 19 in which the second cereal board 51 is disposed, the preliminary sorting air 93 blown rearward and obliquely upward from the second fan 41 is discharged to the suction fan 25 together with sawdust and the like as it is. Since the wind 93a and the return wind 93b that returns to the second conveyor 37 together with the second item, etc., the flow of the second item etc. to the second conveyor 37 is promoted, and the entire swing selection efficiency is improved. To improve Kill.

さらに、前記第一流穀板50の後方延長線上近傍には、予備上ガイド部材94を配設し、該予備上ガイド部材94と前記第二流穀板51とにより形成される予備風路96内の上下略中央位置には、予備下ガイド部材95を配設するので、簡単な構造により前記戻り風93bを発生させることができ、複雑な装置を設置する必要がなく、部品コストの低減やメンテナンス性の向上を図ることができるのである。   Further, a preliminary upper guide member 94 is disposed in the vicinity of the rearward extension line of the first flow grain plate 50, and the preliminary wind path 96 is formed by the preliminary upper guide member 94 and the second flow grain plate 51. Since the auxiliary lower guide member 95 is disposed at the upper and lower approximate center position, the return air 93b can be generated with a simple structure, and it is not necessary to install a complicated device, thereby reducing component costs and maintenance. It is possible to improve the performance.

また、前記予備上ガイド部材94及び第二流穀板51は、いずれも後方になるほど、予備下ガイド部材95との間隔が狭く構成され、上予備風路96a及び下予備風路96bの断面積も後方になるほど小さくなっている。これにより、予備選別風93は後方になっても風速が低下しにくく、高速を維持することができる。また、下予備風路96bの戻り風93bについては、前方になるほど徐々に風速が低下するため、二番コンベア37で搬送中の二番物を吹き上げたりすることがない。   Further, as the spare upper guide member 94 and the second cereal plate 51 are both rearward, the interval between the spare upper guide member 95 and the spare lower guide member 95 is reduced. Is smaller as it goes backwards. Thereby, even if the preliminary | backup selection wind 93 becomes back, a wind speed cannot fall easily and it can maintain a high speed. Further, with respect to the return air 93b of the lower preliminary air passage 96b, the wind speed gradually decreases toward the front, so that the second object being conveyed by the second conveyor 37 is not blown up.

すなわち、前記予備下ガイド部材95により、予備風路96を上予備風路96aと下予備風路96bに分割し、該上予備風路96aと下選別風路96bの終端部の風路断面は、始端部の風路断面よりも小さく構成したので、予備選別風93の風速を高速に維持することができ、風選効率の向上を図ることができ、更に、搬送中の二番物への戻り風93bによる悪影響も最小限に抑えることができるのである。   That is, the preliminary lower guide member 95 divides the preliminary air path 96 into an upper preliminary air path 96a and a lower preliminary air path 96b, and the air path cross section at the end of the upper preliminary air path 96a and the lower selective air path 96b is as follows. Since it is configured to be smaller than the air path cross section of the start end portion, the wind speed of the preliminary sorting wind 93 can be maintained at a high speed, the wind sorting efficiency can be improved, and further to the second object being transported The adverse effect of the return air 93b can be minimized.
