以下本発明を具備するコンバインの脱穀装置について説明する。図１にはこの発明を具備する脱穀装置の切断平面図、図２には脱穀装置の切断正面図、図３には要部の正面図、図４には切り刃の斜視図、図５には切り刃の側面図、図６には切り刃の正面図及び背面図が図示されている。 Hereinafter, a combine threshing apparatus including the present invention will be described. 1 is a plan view of a threshing apparatus equipped with the present invention, FIG. 2 is a front view of the threshing apparatus, FIG. 3 is a front view of the main part, FIG. 4 is a perspective view of the cutting blade, and FIG. Is a side view of the cutting blade, and FIG. 6 shows a front view and a rear view of the cutting blade.

この脱穀装置は、扱室１内に軸架されている扱歯２，…付きの扱胴３、扱胴３の外周部を覆うように設けている受網４、扱室１の側方に設けられている処理室６、処理室６内に軸架されている処理歯７やラセン処理歯７ａ付きの処理胴８、フィードチェン９、排藁チェン１１等により構成されている。 This threshing device includes a handling cylinder 3 with teeth 2,... Pivoted in the handling chamber 1, a receiving net 4 provided so as to cover the outer periphery of the handling cylinder 3, and the side of the handling chamber 1. The processing chamber 6 is provided, a processing tooth 7 pivoted in the processing chamber 6, a processing cylinder 8 with a helical processing tooth 7a, a feed chain 9, a waste chain 11, and the like.

扱室１の供給側のフィードチェン９の上方部位、及び、扱室１の反供給側の受網４の上方部位には、回転する扱歯２，…の左右両側に位置するように切り刃１２，…を配設している。この切り刃１２は例えば次のように製作する。即ち、短冊状の板体をコ字状に屈折して、中央部のホルダー部１３の両側から左右の切り刃１２，１２を突出するように構成し、この切り刃１２，１２における扱歯２の回転方向に対向する縁部には、基部から先端部にかけて凹凸刃縁１４を形成している。この凹凸刃縁１４の凸部１４ａの最も高い部分と凹部１４ｂの最も低い部分とが、切り刃１２の内側面あるいは外側面に沿った正面視で全て一直線上に連続するように形成されている。ホルダー部１３には取付用のボルトを設けている。 Cutting blades are provided at the upper part of the feed chain 9 on the supply side of the handling chamber 1 and the upper part of the receiving net 4 on the opposite side of the handling chamber 1 so as to be positioned on both the left and right sides of the rotating handling teeth 2. 12,... Are arranged. This cutting blade 12 is manufactured as follows, for example. That is, the strip-shaped plate body is refracted into a U-shape, and the left and right cutting blades 12 and 12 are projected from both sides of the center holder portion 13, and the tooth handling 2 in the cutting blades 12 and 12 is configured. An uneven edge 14 is formed from the base part to the tip part at the edge part facing the rotation direction. The highest part of the convex part 14a and the lowest part of the concave part 14b of the concavo-convex blade edge 14 are formed so as to all be continuous in a straight line when viewed from the front along the inner surface or the outer surface of the cutting blade 12. . The holder portion 13 is provided with mounting bolts.

前記凸部１４ａと凹部１４ｂからなる凹凸刃縁１４は、例えば次のようにして製作する。短冊状板材の凹凸刃縁１４形成部分を中途部が内側にへこむ内円弧状に構成しておき、初めに、プレス加工によって短冊状板材の凹凸刃縁１４の形成部分を、略板厚程度外側に傾斜折曲すると共に、プレス加工時に傾斜折曲部分の内側に凹凸を形成する。 The concave / convex edge 14 composed of the convex portion 14a and the concave portion 14b is manufactured as follows, for example. A portion of the strip-shaped plate material is formed in an inner arc shape in which a midway portion is recessed inward, and first, the portion of the strip-shaped plate material formed with the concave-convex blade edge 14 is approximately outside the plate thickness by pressing. In addition, an uneven portion is formed inside the inclined bent portion during press working.

次いで、短冊状板材を中途部からコ字状に折曲してホルダー部１３の左右両側に凹凸面の形成されている切り刃１２，１２を構成し、切り刃１２，１２を焼き入れする。次いで、傾斜折曲部分の外側面を切り刃１２，１２の基部側の外側面に沿うように研削して、切り刃１２，１２の外側面と前記傾斜折曲部の研削面とを面一にし、切り刃１２の板面に直交する方向の側面視で、凹凸刃縁１４の先端部の凸部１４ａから基部の凸部１４ａまでを結ぶ線が中途部で内側にへこむ内円弧状になる凹凸刃縁１４が形成される。しかして、切り刃１２，１２の外側面と同一平面上に最も高い凸部１４ａと最も低い凹部１４ｂとが交互に連続する凹凸刃縁１４が形成される。 Next, the strip-shaped plate material is bent in a U-shape from the middle portion to form the cutting blades 12 and 12 having uneven surfaces formed on the left and right sides of the holder portion 13, and the cutting blades 12 and 12 are quenched. Next, the outer surface of the inclined bent portion is ground along the outer surface on the base side of the cutting blades 12, 12, and the outer surface of the cutting blades 12, 12 and the ground surface of the inclined bent portion are flush with each other. Then, in a side view in a direction perpendicular to the plate surface of the cutting blade 12, a line connecting the convex portion 14a at the front end portion of the concavo-convex blade edge 14 to the convex portion 14a at the base portion becomes an inner arc shape that dents inward in the middle portion. An uneven edge 14 is formed. Thus, the uneven blade edge 14 in which the highest convex portion 14a and the lowest concave portion 14b are alternately arranged on the same plane as the outer surfaces of the cutting blades 12 and 12 is formed.

なお、このように構成された切り刃１２，１２を「内刃型で側面視で凹凸刃縁が内側に円弧状にへこむように刃縁の形成されている」と略称する。
従って、切り刃１２の外側面に沿う方向の正面視で、凹凸刃縁１４の最も高い凸部１４ａと最も低い凹部１４ｂとが一直線上に連続して位置することになり、扱歯２と共に回転する藁屑類を良好に切断することができる。また、切り刃１２を側面視（切り刃１２，１２の板面に対して直交する方向）で先端部の凸部１４ａから基部の凸部１４ａまでを結ぶ仮想線を内側にへこむ内円弧状に構成したので、凹凸刃縁１４の全体で藁屑類を切断することができ、切断性能及び耐久性が向上する。 In addition, the cutting blades 12 and 12 configured in this manner are abbreviated as “inner blade type in which the blade edge is formed so that the concave and convex blade edge is dented in an arc shape in the side view”.
Therefore, in the front view in the direction along the outer surface of the cutting blade 12, the highest convex portion 14a and the lowest concave portion 14b of the concavo-convex blade edge 14 are continuously located on a straight line, and rotate together with the tooth handle 2. Sawdust to be cut can be cut well. Further, in a side view (in a direction orthogonal to the plate surface of the cutting blades 12 and 12), the cutting blade 12 has an inner arc shape that dents inward from a virtual line connecting the convex portion 14a at the distal end to the convex portion 14a at the base portion. Since it comprised, the shavings can be cut | disconnected by the whole uneven | corrugated blade edge 14, and cutting performance and durability improve.

なお、切り刃１２の側面視で先端部の凸部１４ａから基部の凸部１４ａまでを結ぶ仮想線を中途部が外側にふくらむような円弧状に形成すると、扱歯２との相対角度によっては刃縁全長を平均的に使うことができず、部分的に摩耗し切断性能及び耐久性が低下するという不具合が発生するが、前記構成とすることによりこのような不具合も解消できる。 In addition, when a virtual line connecting the convex portion 14a at the tip portion to the convex portion 14a at the base portion in a side view of the cutting blade 12 is formed in an arc shape in which a midway portion bulges outward, depending on a relative angle with the tooth handling 2 The entire length of the blade edge cannot be used on average, and a problem occurs that the cutting performance and durability are deteriorated due to partial wear. However, such a problem can be solved by the above-described configuration.

また、図７に示すように、左右の切り刃１２，１２の外側面に凹凸刃縁１４を構成してもよい。即ち、切り刃１２，１２の内側面と同一平面上に最も高い凸部１４ａと最も低い凹部１４ｂとが交互に一直線上に連続する凹凸刃縁１４を形成し、且つ、凹凸刃縁１４の側面視で先端部の凸部１４ａから基部の凸部１４ａまでを結ぶ仮想線が内側にへこむ内円弧状の曲線になるように刃縁を形成する。なお、このように構成された切り刃１２，１２を「外刃型で側面視で凸部１４ａを連続して結ぶ線が内側に円弧状にへこむように刃縁の形成されている」と略称する。 Moreover, as shown in FIG. 7, you may comprise the uneven | corrugated blade edge 14 in the outer surface of the left and right cutting blades 12 and 12. That is, the concave and convex blade edges 14 in which the highest convex portions 14a and the lowest concave portions 14b are alternately arranged on the same plane as the inner side surfaces of the cutting blades 12 and 12 are formed on the same plane. The edge of the blade is formed so that an imaginary line connecting the convex portion 14a at the tip portion to the convex portion 14a at the base portion becomes an inner arc-shaped curve that dents inward. In addition, the cutting blades 12 and 12 thus configured are abbreviated as “the edge of the blade is formed so that a line continuously connecting the convex portions 14a in an outer blade shape in a side view is recessed inwardly in an arc shape”. To do.

しかして、切り刃１２，１２の内側面に沿って最も高い凸部１４ａ，…と最も低い凹部１４ｂ，…とが同一平面上直線上に連続する凹凸刃縁１４が形成されているので、藁屑類の切断性能が向上し、凹凸刃縁１４の全体で切断作用をすることができて切断性能及び耐久性を向上させりことができ、また、左右の切り刃１２，１２の外側に凹凸刃縁１４を形成したので、切り刃１２，１２のフラットな内側面が扱歯２に対向し藁屑類の抜けが良くなる。 Therefore, since the concavo-convex blade edge 14 in which the highest convex portion 14a,... And the lowest concave portion 14b,.

しかして、処理歯７と切り刃１２，…とにより切断された藁屑類は、処理歯７の回転により網体２３側に送られ、こなれた藁屑類は網体２３を通過して風選部２４に送られて選別され、処理室６の負荷を軽減することができる。また、藁屑類は送塵板１７，…から切り刃１２，…に送られて切断されるので、切り刃１２，…の切断効率が高まり、また、処理室６の上方部位に切り刃１２，…を設けたので、切り刃１２，…のメンテナンスが容易となる。 Therefore, the sawdust cut by the processing teeth 7 and the cutting blades 12,... Is sent to the mesh body 23 side by the rotation of the processing teeth 7. The load on the processing chamber 6 can be reduced by being sent to the selection unit 24 for selection. Further, since the sawdust is sent from the dust feeding plates 17 to the cutting blades 12 and is cut, the cutting efficiency of the cutting blades 12 is increased, and the cutting blade 12 is disposed above the processing chamber 6. Are provided, the maintenance of the cutting blades 12 is facilitated.

また、処理室６を図４５に示すように構成してもよい。即ち、処理室６内上部に処理胴８の軸心方向に沿わせてコ字形状の切り刃１２を配設し、切り刃１２には一対の凹凸刃縁１４，１４を形成し、この一対の凹凸刃縁１４，１４には切り刃１２の板体に直交する方向視で凸部１４ａと凹部１４ｂとを交互に繰り返す連続した仮想線が内側にへこむように円弧状に刃縁を形成し、処理胴８の軸心方向視において切り刃１２の先端部を処理胴８の処理歯７の回転軌跡内に入り込ませ、切り刃１２の一対の凹凸刃縁１４，１４の間を処理歯７が通過するように構成している。 Further, the processing chamber 6 may be configured as shown in FIG. That is, a U-shaped cutting blade 12 is disposed in the upper portion of the processing chamber 6 along the axial direction of the processing cylinder 8, and a pair of concave and convex blade edges 14 are formed on the cutting blade 12. The concave and convex blade edges 14 and 14 are formed with arc edges so that continuous virtual lines that repeat the convex portions 14a and the concave portions 14b alternately indent in the direction perpendicular to the plate body of the cutting blade 12 are indented. The distal end portion of the cutting blade 12 enters the rotation locus of the processing tooth 7 of the processing cylinder 8 in the axial direction of the processing cylinder 8, and the processing tooth 7 is formed between the pair of concave and convex blade edges 14, 14 of the cutting blade 12. Is configured to pass through.

そして、処理胴８の処理歯７，…の外周部に対向し、且つ、前記切り刃１２，…よりも処理胴８の回転下手側部位に送塵板１７，…を多数対向配置し、処理室６における扱室１下方の風選部２４に対応する内側部分を網体（格子）２３で構成し、こなれた藁屑類が網体２３を通って風選部２４に落下するように構成している。なお、処理室６の網体２３の反対側部分は板体のケーシング２７で被覆している。 Further, a large number of dust feeding plates 17,... Are arranged opposite to the outer peripheral portion of the processing teeth 7,... Of the processing cylinder 8, and more on the lower rotation side portion of the processing cylinder 8 than the cutting blades 12,. The inner part of the chamber 6 corresponding to the wind selection section 24 below the handling chamber 1 is configured by a net (lattice) 23, and the sowed waste is dropped to the wind selection section 24 through the net 23. is doing. A portion of the processing chamber 6 opposite to the net body 23 is covered with a plate casing 27.

そして、切り刃１２のホルダー部１３に沿う直線をＡとし、直線Ａに平行な処理胴８の軸心Ｄを通る直線をＢとし、切り刃１２の取付ボルト２８に沿う直線をＣとすると、直線Ｂと直線Ｃとの交点Ｅは処理胴８の軸心Ｄよりも風選部２４側寄りの機体中心側に位置する関係になる。 A straight line along the holder portion 13 of the cutting blade 12 is A, a straight line passing through the axis D of the processing cylinder 8 parallel to the straight line A is B, and a straight line along the mounting bolt 28 of the cutting blade 12 is C. The intersection E between the straight line B and the straight line C is in a relationship located closer to the airframe center side closer to the wind selection section 24 than the axis D of the processing cylinder 8.

前記のように構成したので、切り刃１２の下方に位置する送塵板１７を大きくすることができて送塵効果が大となり、また、切り刃１２で切断されたこなれた藁屑類を網体２３から迅速に漏下し、負荷の軽減を図ることができる。 Since it comprised as mentioned above, the dust-feeding plate 17 located under the cutting blade 12 can be enlarged, and a dust-feeding effect becomes large, Moreover, the neat wastes cut | disconnected with the cutting blade 12 are made into a net. Leaking from the body 23 quickly can reduce the load.

処理歯７と切り刃１２との関連構成を図４６に示すように構成してもよい。即ち、処理室６内上部に処理胴８の軸心方向に沿わせてコ字形状の切り刃１２，…を配設し、切り刃１２，…には一対の凹凸刃縁１４，１４を形成し、この一対の凹凸刃縁１４，１４は切り刃１２の板体に直交する方向視で多数の凸部１４ａと凹部１４ｂとを交互に繰り返しながら内側にへこむ円弧状、あるいは、直線状に刃縁を形成し、処理胴８の軸心方向視において切り刃１２の先端部を処理胴８の処理歯７の回転軌跡内に入り込ませて、切り刃１２の一対の凹凸刃縁１４，１４の間を処理歯７が通過するように構成し、処理歯７の回転上手側端部を処理胴８の周面から所定角度後退させる傾斜状に構成している。従って、凹凸刃縁１４の内側にへこむ円弧状の円の回転中心は処理胴８の回転中心側に位置することとなる。 A related configuration of the processing tooth 7 and the cutting blade 12 may be configured as shown in FIG. That is, U-shaped cutting blades 12,... Are arranged in the upper portion of the processing chamber 6 along the axial direction of the processing cylinder 8, and a pair of concave and convex blade edges 14, 14 are formed on the cutting blades 12,. The pair of concavo-convex blade edges 14, 14 are formed in a circular arc shape or a linear shape indented inward while repeating a number of convex portions 14 a and concave portions 14 b alternately in a direction perpendicular to the plate body of the cutting blade 12. An edge is formed, and the tip of the cutting blade 12 is inserted into the rotation locus of the processing tooth 7 of the processing cylinder 8 when viewed in the axial direction of the processing cylinder 8, so that the pair of concave and convex blade edges 14, 14 of the cutting blade 12 is formed. The processing teeth 7 pass between them, and the rotation upper side end of the processing teeth 7 is inclined so as to recede from the peripheral surface of the processing cylinder 8 by a predetermined angle. Therefore, the center of rotation of the circular arc that dents inside the uneven edge 14 is positioned on the side of the rotation center of the processing cylinder 8.

前記構成としたので、処理歯７と切り刃１２の凹凸刃縁１４とのオーバーラップが進んでも、凹凸刃縁１４と処理歯７との角度変化が少なく、安定した切れ味を確保することができる。また、凹凸刃縁１４の刃縁が処理歯７に対して食い込むような形状であるため、藁屑類を処理歯７により押し込んで切断でき切れ味を良くすることができる。 Since it was set as the said structure, even if the overlap with the uneven | corrugated blade edge 14 of the processing tooth 7 and the cutting blade 12 progresses, the angle change of the uneven | corrugated blade edge 14 and the processing tooth 7 is small, and the stable sharpness can be ensured. . Moreover, since the blade edge of the concavo-convex blade edge 14 is shaped so as to bite into the processing tooth 7, the sawdust can be pushed by the processing tooth 7 to be cut and the sharpness can be improved.

また、切り刃１２に板体に直交する方向視で多数の凸部１４ａと凹部１４ｂとを交互に繰り返しながら直線状の刃縁を形成したタイプあっては、処理胴７と切り刃１２とのオーバーラップが進につれて、わずかながら刃縁の向い角が大きくなりつつ藁屑類を一直線に押し切るので、負荷変動を少なくすることができる。 Further, if the cutting blade 12 is of a type in which a linear blade edge is formed while alternately repeating a number of convex portions 14a and concave portions 14b in a direction perpendicular to the plate body, As the overlap progresses, the shavings are pushed in a straight line while slightly increasing the direction of the edge of the blade, so that the load fluctuation can be reduced.

また、切り刃１２と処理歯７との関連構成を図４７及び図４８に示すように構成してもよい。即ち、切り刃１２の凹凸刃縁１４を側面視で多数の凸部１４ａと凹部１４ｂとを交互に繰り返しながら内側にへこむ円弧状に刃縁を形成し、処理歯７の回転上手側部分を外側にふくらむ円弧状（図４７に示す）、あるいは、直線状（図４８に示す）に刃縁を形成する。 Moreover, you may comprise the related structure of the cutting blade 12 and the process tooth 7 as shown in FIG.47 and FIG.48. That is, the concave and convex edge 14 of the cutting blade 12 is formed in the shape of an arc that dents inward while alternately repeating a number of convex portions 14a and concave portions 14b in a side view, and the rotation upper side portion of the processing tooth 7 is positioned outside. The blade edge is formed in a circular arc shape (shown in FIG. 47) or a linear shape (shown in FIG. 48).

しかして、図４７の構成では、切り刃１２の凹凸刃縁１４と処理歯７の回転上手側部分がオーバーラップする際に、接触長さが長くなり藁屑類を一挙に切断できる。また、図４８に示すように側面視で凹凸刃縁１４の刃縁を直線状に形成したものにあっては、凹凸刃縁１４と処理歯７とのオーバーラップ部分が短くなり、負荷を軽減しながら藁屑類を切断することができる。 47, when the concavo-convex edge 14 of the cutting blade 12 and the rotating upper side portion of the processing tooth 7 overlap, the contact length becomes long and the chips can be cut at a time. In addition, in the case where the edge of the uneven edge 14 is formed in a straight line as seen from the side as shown in FIG. 48, the overlap portion between the uneven edge 14 and the processing tooth 7 is shortened to reduce the load. The sawdust can be cut while.

また、切り刃１２と処理歯７とを図４９及び図５０に示すように構成してもよい。即ち、切り刃１２の凹凸刃縁１４を側面視で多数の凸部１４ａと凹部１４ｂとを交互に繰り返しながら内側にへこむ円弧状（図４９に示す）、あるいは、直線状（図５０に示す）になるように刃縁を形成し、処理歯７の回転上手側部分を処理胴８の外周面から略直角に起立するように構成する。 Moreover, you may comprise the cutting blade 12 and the process tooth 7 as shown in FIG.49 and FIG.50. That is, the concave / convex edge 14 of the cutting blade 12 has an arc shape (shown in FIG. 49) or a straight shape (shown in FIG. 50) that is recessed inward while alternately repeating a number of convex portions 14a and concave portions 14b in a side view. The blade edge is formed so that the upper rotation side portion of the processing tooth 7 rises from the outer peripheral surface of the processing cylinder 8 at a substantially right angle.

しかして、図４９に示す構成にあっては、処理歯７が藁屑類を持ち回るように回転するので、消費馬力は大きくなるが切断性能を高めることができる。また、図５０に示す側面視で凹凸刃縁１４の刃縁を直線状に形成したものにあっては、凹凸刃縁１４と処理歯７とのオーバーラップ部分が短くなり、負荷を軽減しながら藁屑類を切断することができる。 Therefore, in the configuration shown in FIG. 49, the processing teeth 7 rotate so as to carry the sawdust, so that the cutting performance can be improved although the power consumption is increased. In addition, in the case where the edge of the concavo-convex edge 14 is formed in a straight line in a side view shown in FIG. 50, the overlap portion between the concavo-convex edge 14 and the processing tooth 7 is shortened, and the load is reduced. Sawdust can be cut.
