A reaping machine 4 including a root / tip transfer device 14a, 14b and the like is provided. The reaper 4 is configured to move up and down with respect to the soil surface by a telescopic cylinder 5 that is hydraulically driven.

前記刈取機４の前方下部から後方上部へ傾斜する支持杆１５ａの上端部には、左右方向の支持パイプ杆（支持パイプ）１５ｂを設け、この支持パイプ杆１５ｂを走行車台２の上側面に設けた支持装置１５ｃで回動自在に支持させて、昇降シリンダ５の作動により、刈取機４は支持パイプ杆１５ｂを回動中心として、上下に回動する構成である。 A support pipe rod (support pipe) 15b in the left-right direction is provided at the upper end portion of the support rod 15a inclined from the front lower portion to the rear upper portion of the reaper 4, and this support pipe rod 15b is provided on the upper side surface of the traveling chassis 2. The reaper 4 is supported by the support device 15c so as to be rotatable, and the reaping cylinder 5 is rotated up and down around the support pipe rod 15b by the operation of the elevating cylinder 5.

前記刈取機４の穀稈供給移送装置１３によって形成される穀稈移送経路中には、刈取られて移送される穀稈に接触作用することにより、脱穀機６へ穀稈の供給の有無を検出する穀稈センサ４ａを設けた構成である。 The presence / absence of supply of cereal to the threshing machine 6 is detected in the cereal transport path formed by the cereal supply / transfer device 13 of the reaper 4 by contacting the cereal that is harvested and transferred. It is the structure which provided the grain candy sensor 4a to perform.

前記刈取機４の穀稈供給移送装置１３の根元・穂先移送装置１４ａ，１４ｂで移送される穀稈を引継ぎして移送する補助穀稈移送装置８は、図１〜図３で示す如く脱穀機６の前側で、刈取機４の左側端部のこの刈取機４へ装着した構成である。 The auxiliary culm transfer device 8 that takes over and transfers the cereals transferred by the root and tip transfer devices 14a and 14b of the cereal supply and transfer device 13 of the reaper 4 is a threshing machine as shown in FIGS. 6, the front end of the reaper 6 is attached to the reaper 4 at the left end of the reaper 4.

前記補助穀稈移送装置８は、図１〜図３で示す如く内側には、内補助チェン８ａを張設すると共に、外側には、外補助チェン８ｂを張設した構成である。これら内・外補助チェン８ａ，８ｂは、駆動装置９により、回転駆動される構成である。この内補助チェン８ａの移送終端部の下側には、駆動装置９の伝動機構（第１伝動機構）９ｂを内装した補助ギヤーケース９ａを設け、この補助ギヤーケース９ａの伝動機構９ｂへの回転動力は、刈取機４の支持パイプ杆１５ｂへ内装した伝動機構（第２伝動機構）１５ｄから、伝動ベルト１５ｅを介して入力される構成である。この入力により、内補助チェン８ａが回転駆動される構成である。 As shown in FIGS. 1 to 3, the auxiliary grain transfer device 8 has a configuration in which an inner auxiliary chain 8 a is stretched on the inner side and an outer auxiliary chain 8 b is stretched on the outer side. These inner / outer auxiliary chains 8 a and 8 b are configured to be rotationally driven by the driving device 9. An auxiliary gear case 9a having a transmission mechanism (first transmission mechanism) 9b of the driving device 9 is provided below the transfer terminal end of the auxiliary chain 8a, and the auxiliary gear case 9a is rotated to the transmission mechanism 9b. Power is input from the transmission mechanism (second transmission mechanism) 15d built in the support pipe rod 15b of the reaper 4 via the transmission belt 15e. By this input, the inner auxiliary chain 8a is rotationally driven.

前記内補助チェン８ａの移送始端に設けた回動軸１５ｆから、外補助チェン８ｂの移送終端部が回動駆動される構成である。これにより、外補助チェン８ｂが回転駆動される構成である。 The transfer terminal portion of the outer auxiliary chain 8b is rotationally driven from a rotation shaft 15f provided at the transfer start end of the inner auxiliary chain 8a. Thus, the outer auxiliary chain 8b is driven to rotate.

前記刈取機４は、図１〜図３で示す如く走行車台２の上側へ設けた開閉装置１０の回動軸１０ａを回動支点（イ）として、コンバイン１の左外側へ開閉自在に回動移動する構成である。 As shown in FIGS. 1 to 3, the reaper 4 is pivotably pivotable to the left outer side of the combine 1 with a pivot shaft 10 a of an opening / closing device 10 provided on the upper side of the traveling chassis 2 as a pivot fulcrum (A). It is a configuration that moves.

前記刈取機４で刈取り後方上部へ移送され穀稈は、脱穀機６の前側で、刈取機４の左端部側へ設けた補助穀稈移送装置８の内・外補助チェン８ａ，８ｂとで引継ぎされ、脱穀機６のフィードチェン７ａと、挟持杆７ｂとへ供給されると共に、開閉自在に設けた刈取機４は、開閉装置１０を回動支点（イ）として、外側へ開操作すると、この刈取機４は外側へ開回動移動すると共に、この回動移動に連動して、補助穀稈移送装置８の内・外補助チェン８ａ，８ｂも同時に、外側へ開回動移動することにより、この補助穀稈移送装置８の内補助チェン８ａを、補助ギヤーケース９ａで駆動する伝動ベルト１５ｅ、及び内・外用リンクの着脱が不用となる。更に、外側へ回動移動させることにより、刈取機４の下部が開放状態となり、各部のメンテナンスが容易になる。 The cereals that have been transferred to the rear upper part of the reaping machine 4 by the reaper 4 are taken over by the inner and outer auxiliary chains 8a and 8b of the auxiliary pestle transfer device 8 provided on the front side of the threshing machine 6 and on the left end side of the reaping machine 4. The reaping machine 4 that is supplied to the feed chain 7a and the holding basket 7b of the threshing machine 6 and that can be freely opened and closed is opened to the outside with the opening and closing device 10 as a rotation fulcrum (I). As the reaper 4 moves outward and pivots outward, the inner and outer auxiliary chains 8a and 8b of the auxiliary grain feeder 8 are simultaneously opened and moved outward in conjunction with the rotational movement. It becomes unnecessary to attach and detach the transmission belt 15e that drives the inner auxiliary chain 8a of the auxiliary grain transfer device 8 with the auxiliary gear case 9a and the inner and outer links. Furthermore, by rotating outward, the lower part of the reaper 4 is opened, and maintenance of each part is facilitated.

The auxiliary gear case 9a of the device 9 is provided so as to be positioned in front of the left side.

前記刈取機４を外側へ開閉させる開閉装置１０の回動軸１０ａである回動支点（イ）は、穀稈を刈取機４から引継ぎして、移送する補助穀稈移送装置８の内補助チェン８ａを回転駆動する駆動装置９の補助ギヤーケース９ａより、左側部の前方部へ位置させて設けたことにより、刈取機４の開閉が容易である。又、この刈取機４の下部が開放状態になることにより、各部のメンテナンスが容易である。 The rotation fulcrum (I), which is the rotation shaft 10a of the opening / closing device 10 that opens and closes the reaper 4 to the outside, takes over the cereal from the reaper 4 and transfers it. By providing the auxiliary gear case 9a of the driving device 9 that rotationally drives the 8a to the front portion on the left side, the reaper 4 can be easily opened and closed. Moreover, the maintenance of each part is easy because the lower part of this reaper 4 becomes an open state.

Is attached by bolts or the like, and the front end portion on one side of the lifting cylinder 5 is attached to the mounting plate 17 by a front mounting pin 5a. On the upper side surfaces of the front support frames 2a, 2a of the traveling chassis 2, the upper and lower support metals 18a, 18b of the support device 18 that supports the support pipe 15b at the upper end of the support rod 15a are located at predetermined positions in the left-right direction. In the lower rear part of the lower support metal 18b, the rear end part of the other side of the elevating cylinder 5 is provided by being attached by a rear attachment pin 5b.

前記支持杆１５ａの取付板１７と、下支持メタル１８ｂとへ装着した昇降シリンダ５は、側面視走行装置３の走行クローラ３ａより、上部へ位置させて設け、刈取機４を開閉装置１０の回動軸１０ａを回動支点（イ）として、左外側へ開閉回動移動させたときであっても、昇降シリンダ５は、走行クローラ３ａへ当接しない構成である。 The elevating cylinder 5 attached to the mounting plate 17 of the support rod 15a and the lower support metal 18b is provided so as to be positioned above the traveling crawler 3a of the side view traveling device 3, and the reaper 4 is rotated by the opening / closing device 10. Even when the moving shaft 10a is used as a rotation fulcrum (A) and opened / closed to the left outer side, the elevating cylinder 5 does not contact the traveling crawler 3a.

前記刈取機４を昇降させる昇降シリンダ５は、走行装置３の走行クローラ３ａより、側面視上方部へ位置させて設けたことにより、刈取機４を左外側へ開閉回動移動させたときであっても、昇降シリンダ５が走行クローラ３ａへ当接することがなく、このために、昇降シリンダ５を取り外す必要がない、又、このために、回動移動操作が容易である。更に、この昇降シリンダ５は、高所位置となったことにより、泥等の溜まり、及び付着を防止することができる。 The lifting cylinder 5 for raising and lowering the reaper 4 is located above the traveling crawler 3a of the traveling device 3 so as to be located at an upper part in a side view, and thus when the reaper 4 is opened and closed to the left outer side. However, the lifting / lowering cylinder 5 does not come into contact with the traveling crawler 3a. Therefore, it is not necessary to remove the lifting / lowering cylinder 5, and for this reason, the rotational movement operation is easy. Furthermore, since this elevating cylinder 5 is at a high position, it is possible to prevent accumulation and adhesion of mud and the like.
