JP 2001-37319 A

上記穀稈搬送構造は、刈取り部を横外側方に旋回開放することで、刈取り部の背部を大きく露出させることができ、刈取り部の各部における点検整備や穀稈搬送系での詰まり除去、などを容易に行うことができるとともに、エンジン周りも機体内方から開放できるので、エンジンから各部への伝動系の点検整備も刈取り部の移動によって大きく空けられた空間から容易に行うことができる利点を有するものである。   The above cereal transport structure allows the back part of the reaping part to be largely exposed by opening the reaping part to the laterally outward direction, and inspection and maintenance at each part of the reaping part and removal of clogging in the cereal transportation system, etc. Since the engine can be opened from the inside of the aircraft, the inspection and maintenance of the transmission system from the engine to each part can be easily performed from the space that is largely opened by the movement of the cutting part. It is what you have.

本発明は、刈取り部の旋回開放させることによる上記利点を発揮させながら、刈取り部から脱穀装置への穀稈供給搬送を確実良好に行うことのできるようにすることを目的としている。   An object of the present invention is to make it possible to reliably and reliably carry and supply cereal straw from the reaping unit to the threshing device while exhibiting the above-described advantages by opening the reaping portion.

第1の発明は、走行機体の前部に連結された刈取り部をその基部を中心にして横外側方に旋回開放可能に構成した自脱型コンバインの穀稈搬送構造であって、
前記刈取り部に備えられた供給搬送装置の終端部と脱穀装置に装備されたフィードチェーンの始端部との間の所定位置に、搬送チェーンを縦回し巻回してなる補助搬送装置を配備すると共に、前記補助搬送装置を前記刈取り部に対して走行機体側に設置し、前記補助搬送装置の入力部を前記補助搬送装置の機体横外方側に配設すると共に、前記刈取り部の基部に横架されたカウンター軸を前記補助搬送装置の下側を連通させて前記補助搬送装置の機体横外方側に延出し、前記カウンター軸の延出端部と前記補助搬送装置の入力部とを前記補助搬送装置の機体横外方側で伝動チェーンを介して連動連結してあることを特徴とする。
The first aspect of the present invention is a self-decomposing combine cereal transporting structure configured such that a cutting portion connected to the front portion of the traveling machine body can be pivotally opened laterally outward with its base as the center,
While deploying an auxiliary transport device formed by rotating the transport chain vertically at a predetermined position between the terminal end portion of the feed transport device provided in the mowing unit and the start end portion of the feed chain equipped in the threshing device , The auxiliary transport device is installed on the traveling machine body side with respect to the cutting unit, the input unit of the auxiliary transport device is disposed on the laterally outer side of the auxiliary transport device, and is horizontally mounted on the base of the cutting unit. has been a counter shaft extending in the machine body transverse outer side of the auxiliary transport device communicates the lower side of the auxiliary transport device, said auxiliary and input portion of the extension end portion of the counter shaft and the auxiliary conveying device It is characterized in that it is interlocked and connected via a transmission chain on the laterally outer side of the carrier body .

上記構成によると、刈取り部で刈取り収穫された穀稈は供給搬送装置によって後方に搬送された後、脱穀装置のフィードチェーンに受け渡し供給されるのであるが、供給搬送装置の終端に至った穀稈は補助搬送装置によって強制的にフィードチェーンの始端部に搬送されることになり、脱穀装置前部の穀稈供給口付近での滞留のない穀稈供給が行われる。   According to the above configuration, the culm harvested and harvested by the reaping part is transported backward by the supply and transport device, and then delivered and supplied to the feed chain of the threshing device, but the culm that has reached the end of the supply and transport device Is forcibly conveyed to the starting end of the feed chain by the auxiliary conveying device, and cereal supply without stagnation near the cereal supply port at the front of the threshing device is performed.

ここで、補助搬送装置は刈取り部に連動連結されて同調駆動されるので、単位時間あたりの収穫量の増大、等に伴って供給搬送装置の搬送速度を速くすると、補助搬送装置の搬送速度も速くなり、逆に、単位時間あたりの収穫量の減少、等に伴って供給搬送装置の搬送速度を遅くすると補助搬送装置の搬送速度も遅くなり、供給搬送装置から補助搬送装置への受継ぎ搬送が、常に穀稈の滞留や姿勢乱れの少ないものとなる。   Here, since the auxiliary conveyance device is interlocked and connected to the mowing unit and driven synchronously, if the conveyance speed of the supply conveyance device is increased as the yield per unit time increases, the conveyance speed of the auxiliary conveyance device is also increased. On the other hand, if the transport speed of the supply transport device is slowed due to a decrease in the yield per unit time, etc., the transport speed of the auxiliary transport device also slows down, and the inherited transport from the supply transport device to the auxiliary transport device However, there will always be less cereal stagnation and posture disturbance.

また、刈取り部におけるカウンター軸の延出端部に備えられたスプロケット、あるいは、補助搬送装置の入力部に備えられたスプロケットから伝動チェーンを外すことで、刈取り部を横外側方に旋回開放することができ、刈取り部の点検整備や詰まり除去、あるいは、刈取り部で隠されていた機体内部の点検整備、などを開放した刈取り部の背部に空けられた広い空間から行うことができる。この場合、カウンター軸を補助搬送装置の下側を連通させて補助搬送装置の機体横外方側に延出し、補助搬送装置を刈取り部に対して走行機体側に設置しているので、刈取り部を横外方に放回開放する際に、カウンター軸と補助搬送装置とが互いに干渉し合うことがなく、刈取り部を無理なく横外方に放回開放することができる。 Further, a sprocket provided on the extending end portion of the counter shaft in the cutting section or, by removing the transmission chain from the sprocket provided in the input portion of the auxiliary transporting device, to pivot open the cutting portion laterally outward It is possible to carry out inspection and maintenance of the cutting part, removal of clogging, or inspection and maintenance of the inside of the machine body hidden by the cutting part from a wide space opened at the back of the cutting part. In this case, the counter shaft is communicated with the lower side of the auxiliary transport device and extended to the lateral outer side of the auxiliary transport device , and the auxiliary transport device is installed on the traveling machine body side with respect to the mowing unit. The countershaft and the auxiliary transport device do not interfere with each other when the spring is released laterally outwardly, and the mowing part can be released laterally outward without difficulty.

従って、第1の発明によると、刈取り部を旋回開放させることによる利点を発揮させながら、刈取り部から脱穀装置への穀稈供給搬送を確実良好に行うことのできるようになった。しかも、補助搬送装置を取外さなくても簡単に刈取り部を旋回操作することができ、メンテナンス時における作業性にも優れたものとなる。   Therefore, according to 1st invention, the grain supply and conveyance from the reaping part to the threshing apparatus can be reliably and satisfactorily performed while demonstrating the advantage obtained by turning and opening the reaping part. In addition, the cutting part can be easily turned without removing the auxiliary transport device, and the workability during maintenance is excellent.

According to a third invention, in the first or second invention,
The return path of the transmission chain is elastically pressed with a tie toner made of a leaf spring material, and an operation portion for placing a finger on the free end portion of the tie toner is continuously provided.

上記構成によると、刈取り部を横外側方に旋回開放する操作に先立って、刈取り部におけるカウンター軸の端部に備えられたスプロケット、あるいは、補助搬送装置の入力部に備えられたスプロケットから伝動チェーンを外すことになるが、この場合、タイトナーの遊端に形成した操作部に指をかけてタイトナーを撓み変形させて伝動チェーンを弛めることができ、刈取り部の旋回のための準備が簡単に行える。 According to the above configuration, prior to the operation of turning and opening the mowing portion laterally outward, the transmission chain is connected to the sprocket provided at the end of the counter shaft in the mowing portion or the sprocket provided in the input portion of the auxiliary transport device. In this case, the transmission chain can be loosened by placing a finger on the operation portion formed at the free end of the Tightener to bend and deform the Tightener, and preparation for turning the cutting portion can be easily performed. .

刈取り部3を前方に向かう通常の位置から、図8に示すように、機体左横側方に揺動開放するには、先ず、刈取り部3を上昇させた状態で持上げロック用の角ブロック64を振り上げ回動して受け部65に載せつけ、その後、図11(ロ)に示すように、刈取り部3を下降させて基端ボス部7aに一体形成した接当部56を角ブロック64の上に載せつけ、それ以上に刈取り部3が下降されるのを阻止する。このように角ブロック64を介して下降が阻止された状態では刈取り部3は地上から浮き上がった高さで保持されることになり、この状態で刈取りフレーム7と油圧シリンダ9との連結を解除するとともに、右側の軸受け部52を開放し、刈取り部3を縦軸心X周りに揺動開放することができる。 As shown in FIG. 8, in order to swing and release the mowing unit 3 from the normal position toward the front side to the left side of the machine body, first, the angle block 64 for lifting lock with the mowing unit 3 raised. 11a and 11b, after that, as shown in FIG. 11 (b), the cutting portion 3 is lowered and the contact portion 56 formed integrally with the proximal end boss portion 7a is attached to the square block 64. It is put on and prevents the cutting part 3 from being lowered further. Thus, in a state where the lowering is prevented via the corner block 64, the cutting unit 3 is held at a height that is lifted from the ground. In this state, the connection between the cutting frame 7 and the hydraulic cylinder 9 is released. At the same time, the right bearing portion 52 can be opened, and the cutting portion 3 can be swung open about the longitudinal axis X.

ここで、刈取り部3の旋回開放操作に先立って、カウンター軸33と補助搬送装置22との連動を解除しておく必要があり、先ず、タイトナー遊端に備えた操作部46aに手指をかけて引き降ろしてタイトナー46を下方に撓ませて伝動チェーン45を弛ませ、次に、例えば、カウンター軸33のスプロケット44から伝動チェーン45を外し、外した伝動チェーン45を入力軸42のスプロケット43に掛けて垂らしておく。また、ガイドレール24,60を振り上げ格納するか取外して、ガイドレール24と搬送チェーン23およびガイドレール60とフィードチェーン21との引っ掛かりを外し、その後、刈取り部3の旋回開放操作するのである。 Here, it is necessary to release the interlocking between the counter shaft 33 and the auxiliary transport device 22 prior to the turning opening operation of the cutting unit 3. First, a finger is applied to the operation unit 46 a provided at the Tightner free end. The transmission chain 45 is slackened by pulling down to bend the Tightener 46 downward. Next, for example, the transmission chain 45 is removed from the sprocket 44 of the counter shaft 33, and the removed transmission chain 45 is hung on the sprocket 43 of the input shaft 42. Let it hang down. Further, the guide rails 24, 60 are swung up and stored or removed, the guide rail 24, the transport chain 23, the guide rail 60, and the feed chain 21 are unhooked, and then the pivoting release operation of the cutting unit 3 is performed.
