の穀稈搬送装置に関するものである。[Detailed description of the invention] The present invention has a transverse transportation mechanism for harvested grain culms placed horizontally behind a pair of left and right pulling devices, and a reaping route for both raising and reaping grains between the pulling devices and the horizontal transportation mechanism. A pair of auxiliary conveyance mechanisms are provided to draw the grain culms rearward and guide them to the horizontal conveyance mechanism, and both of the auxiliary conveyance mechanisms are configured to be driven to rotate about their vertical axes in opposite directions so that their respective lateral outer portions serve as conveyance action parts. This invention relates to a grain culm conveying device for a combine harvester.

この型式の搬送装置は次のような理由から、前記一対の
補助搬送機構は夫々の横外側部を搬送作用部としている
。In this type of conveyance device, the pair of auxiliary conveyance mechanisms have their respective lateral outer portions serving as conveyance action portions for the following reasons.

倒伏穀稈を追い刈りするときに、早い時期に横搬送機構
に株元を受け渡して機体内に株元を引き込んでしまうと
、残された倒伏穀稈穂先側はいまだ引起し途中にあるた
めに、引起し爪で扱かれて脱粒を生じてしまう。When reaping a lodging grain culm, if the stock head is transferred to the horizontal transport mechanism early and the stock head is pulled into the machine, the tip of the lodged grain culm that remains is still in the process of being pulled up. , the particles are handled by the lifting claws, causing shedding.

そこで、前記横搬送機構の搬送上手側に位置した補助搬
送機構については、株元に対して比較的長い引込み経路
が得られるように、補助搬送機構の外側部を通して、横
搬送機構の搬送上手側にその株元を供給する迂回経路の
構成にしてある。Therefore, for the auxiliary transport mechanism located on the upper side of the horizontal transport mechanism, in order to obtain a relatively long pull-in route to the stock head, the auxiliary transport mechanism is A detour route is configured to supply the stock to the company.

一方、前記横搬送機構の搬送下手側に位置する補助搬送
機構は、横搬送機構の搬送終端に近くて、株元部の振り
回しによる姿勢乱れを防止できる有利な位置にあるので
、前記のような迂回経路とせずに、横搬送機構の搬送終
端に近い側の搬送面である横外側部を搬送作用部にして
、穀稈姿勢の乱れ抑制効果を優先させた構成にしてある
。On the other hand, the auxiliary conveyance mechanism located on the downstream side of the horizontal conveyance mechanism is close to the conveyance end of the horizontal conveyance mechanism and is in an advantageous position where it can prevent posture disturbance due to swinging of the stock base. Rather than using it as a detour route, the lateral outer portion, which is the transport surface near the end of the transport of the lateral transport mechanism, is used as the transport action part, giving priority to the effect of suppressing disturbances in grain culm posture.

このような理由から、一対の補助搬送機構は夫々の横外
側部を搬送作用部とするように互いに反対方向に駆動さ
れているが、従来では一対の補助搬送機構によって搬送
される穀稈のうち、前記迂回経路を採って横搬送される
穀稈は、補助搬送機構の後ろに位置した横搬送機構だけ
から搬送力を受けていたので、ボリュームが少なくて前
倒れ気味となったとき等に搬送力を受け難くなることが
あった。For this reason, the pair of auxiliary conveyance mechanisms are driven in opposite directions so that their respective lateral outer portions serve as conveyance action parts. The grain stems that were transported horizontally by taking the detour route received the transport force only from the horizontal transport mechanism located behind the auxiliary transport mechanism, so when the grain volume was small and the grain tended to fall forward, it was difficult to transport the grain. There were times when I found it difficult to accept force.

本考案は、簡単な改良で、横搬送性能の向上と前記一対
の補助搬送機構に対する駆動構造の簡略化とを同時に満
たすことのできるコンバインの穀稈搬送装置を提供しよ
うとするものである。The present invention aims to provide a grain culm conveying device for a combine harvester that can simultaneously improve lateral conveyance performance and simplify the drive structure for the pair of auxiliary conveyance mechanisms through simple improvements.

本考案が講じた技術的手段は次の通りである。The technical measures taken by the present invention are as follows.

即ち、考案の詳細な説明の冒頭に記載したコンバインの
穀稈搬送装置であって、前記両補助搬送機構を、横架巻
回した搬送突起付きチェーンで巻掛連動するとともに、
このチェーンの後側回動径路部を前記横搬送機構と同方
向に回動する横搬送作用部に構成してあることを特徴と
する。That is, in the grain culm conveying device for a combine harvester described at the beginning of the detailed description of the invention, both the auxiliary conveying mechanisms are wound and interlocked by a horizontally wound conveying protrusion chain, and
The chain is characterized in that the rear rotation path portion of the chain is configured as a lateral conveyance acting portion that rotates in the same direction as the lateral conveyance mechanism.

従って、本考案の穀稈搬送装置であれば、前記突起付き
チェーンと横搬送機構とで横搬送穀稈をその前後から支
持して強力且つ確実に横搬送することが可能で、前倒れ
気味の穀稈も良好に搬送できる。Therefore, with the grain culm conveying device of the present invention, the chain with protrusions and the lateral conveyance mechanism can support the lateral conveyed grain culm from the front and back, and can strongly and reliably convey the grain culm horizontally. Grain culms can also be transported well.

しかも、前記一対の補助搬送機構は夫々の横外側部を搬
送作用部としているので、両者の間にチェーンを巻回し
ても、当該チェーンが穀稈の搬送の障害とならない点に
着目し、前記横搬送を補助するための突起付きチェーン
を、両補助搬送機構を連動させるための駆動手段に有効
利用したので、一対の補助搬送機構に対する駆動構造を
も同時に簡略化できる。Moreover, since the pair of auxiliary conveyance mechanisms have their respective lateral outer portions as conveyance action parts, even if a chain is wound between them, the chain does not become an obstacle to the conveyance of grain culms. Since the chain with protrusions for assisting lateral conveyance is effectively used as the drive means for interlocking both auxiliary conveyance mechanisms, the drive structure for the pair of auxiliary conveyance mechanisms can be simplified at the same time.
