【考案の詳細な説明】
本考案は、複数枚の回転刃を固定した一対のカッター軸
間に藁等の長形の被切断物を通過させ所定寸法に切断す
るよう構成した回転刃式カッターに関するものである。[Detailed description of the invention] The present invention relates to a rotary blade cutter configured to cut a long object such as straw into a predetermined size by passing it between a pair of cutter shafts to which a plurality of rotary blades are fixed. It is something.
この種の回転刃式カッターは、コンバイン、自走式脱穀
機等の脱穀装置を有する農用作業機に装着され脱穀装置
により脱穀処理された藁等を所定寸法に細断して圃場に
放出すべく使用されるが、従来装置においては、藁等が
カッターケースの中間部に供給されるので両側の回転刃
とカッターケース側板との間隔は回転刃の相互間隔より
も大となっている。This type of rotary blade type cutter is attached to an agricultural working machine equipped with a threshing device, such as a combine harvester or a self-propelled threshing machine, and is used to shred straw, etc. that has been threshed by the threshing device, and to shred it into predetermined sizes and release it into the field. However, in the conventional device, since straw or the like is supplied to the middle part of the cutter case, the distance between the rotary blades on both sides and the side plates of the cutter case is larger than the mutual distance between the rotary blades.
しかし、この種の農用作業機においては脱穀装置におけ

断藁に所望寸法よりも長いものが存在し、以後の圃場作
業に際し藁が耕耘機、播種機等に巻き付き後作業を困難
にする欠点がある。In this case, the cut size on the side plate of the cutter case is longer than other parts, and some of the cut straw that is shredded and released into the field is longer than the desired size, and during subsequent field work, the straw is cut into pieces by the tiller. However, it has the disadvantage that it becomes difficult to work after wrapping around seeding machines and the like.
本考案は、圃場に放出された切断藁等に所望寸法以上の
ものを無くし上記の欠点を除去することを目的とするも
ので゛ある。The purpose of the present invention is to eliminate the above-mentioned drawbacks by eliminating cut straw, etc., released into the field that exceeds a desired size.
本考案は、両側端の回転刃とカッターケース側板との間

A shaft joint 4 is fixed to both ends of a blade mounting shaft 2 by a screw rod 3, and a plurality of rotating blades 5 are mounted on the blade mounting shaft 2, and a blade support 6 is mounted on the blade mounting shaft 2.
[In the cutter shaft 1', the blade support 8 also acts as the blade support 6], which is fixed in a predetermined position by the collar 7 and the cylindrical body 4a fixed to the tip of the shaft joint 4. A wrapping prevention collar 9 is provided with a small diameter wrapping prevention collar 10 on the outer periphery of the cylinder 4a, and is rotatably supported on a cutter case side plate 13 via a shaft joint 4, a bearing 11, and a bearing case 12. , large gear 1 on cutter shaft 1
4, a small gear 15 is keyed to the cutter shaft 1', the small gear 15 is engaged with the large gear 14, the large gear 14 is engaged with the drive gear 16, and the drive gear 16, Double-edged vine shaft 1 via large gear 14 and small gear 15
. The distance IB between the rotary blade 5a and the cutter case side plate 13 is:
It is determined by the blade support 6, the shaft joint 4 including the cylinder 4a, and the collar 7, and lA≧lB is satisfied.
第３図を参照して、カッターケースの供給口Ｐより落下
した藁等Ｍはカッター軸１，１′間を通過して切断され
、切断藁Ｍが放出口Ｑより圃場に向は放出される。Referring to Fig. 3, straw, etc. M that has fallen from the supply port P of the cutter case passes between the cutter shafts 1 and 1' and is cut, and the cut straw M is discharged from the discharge port Q into the field. .
切断藁Ｍの切断長は、中間部で切断されたものはｌＡで
あり、両側部で切断されたものはｌＢであって、ｌＡ≧
１８であるから、すべてｈ以下（同−若しくはそれより
小さい値）である。The cutting length of the cut straw M is 1A if it is cut in the middle, and 1B if it is cut on both sides, and 1A≧
18, all values are less than h (the same value or smaller than h).
従って回転刃の相互間隔ｌＡ組以上切断藁Ｍは存在しな
い。Therefore, there is no cutting straw M with a mutual spacing of 1A between the rotary blades.
本考案は、上述したように、両側の回転刃とカッターケ
ース側板との間隔を、回転刃の相互間隔以下としたから
圃場に放出された切断藁等を、所望寸法である回転刃相
互間隔以下とし、耕耘作業等の後作業を円滑に行なうこ
とができる。As mentioned above, in this invention, the distance between the rotary blades on both sides and the side plate of the cutter case is set to be equal to or less than the mutual distance between the rotary blades. This makes it possible to perform post-tillage work smoothly.
また、軸接手を短かくすることができて組立作業を容易
にすることができる。Furthermore, the shaft joint can be shortened, making assembly work easier.
また、回転刃を、カッターケース内に位置する刃取付軸
とカッターケース側板に支持される左右一対の軸接手と
で構威し少くとも片方の軸接手に対する軸受ケースをカ
ッターケース側板に対して着脱自在としたから、軸接手
を取外すことにより回転刃とともに刃取付軸を左右振替
えを可能とし、回転刃の左右位置の振替がきわめて簡単
容易である。In addition, the rotary blade is composed of a blade mounting shaft located inside the cutter case and a pair of left and right shaft joints supported by the cutter case side plate, and the bearing case for at least one shaft joint is attached to and detached from the cutter case side plate. Since the rotary blade is freely movable, it is possible to change the rotary blade and the blade mounting shaft from side to side by removing the shaft joint, and it is extremely easy to change the left and right positions of the rotary blade.
上述の回転軸の左右振替で摩耗のはげしい株元側を穂先
側へ移動させて回転刃の摩耗を平均化することができる
が、この際、両方の側端の回転刃とカッターケース側板
との間が回転刃の相互間隔以下としたので、上述の効果
は回転軸を左右振替えても達成することができる。By reversing the rotary shaft from side to side as described above, it is possible to move the heavily worn stock side to the tip side and average out the wear on the rotary blades. Since the spacing is set to be equal to or less than the mutual spacing of the rotary blades, the above-mentioned effect can be achieved even if the rotary shaft is changed from left to right.
