【考案の詳細な説明】 本考案はコンバインの脱穀装置から排出される
排藁を結束機で結束し、結束機の放出アームが放
出した藁束を既刈地側へ排送し、その終端から落
下させて圃場に起立せしめる装置に関する。[Detailed description of the invention] This invention binds waste straw discharged from the threshing device of a combine using a tying machine, and discharges the straw bundles released by the discharge arm of the tying machine to the already cut field side, and from the end of the straw bundles. It relates to a device that is dropped and erected in a field.

くすべく搬送終端で立姿勢で落下させて既刈圃場
に起立せしめる場合、搬送速度が遅い方が放出時
の慣性力が小さく良好な起立姿勢で着地させるこ
とができる。 In general, when straw bundles are conveyed by holding the panicle side, and then dropped in an upright position at the end of the conveyance to stand up on a harvested field in order to improve drying, the slower the conveyance speed is, the smaller the inertia force at the time of release is, which is better. Can be landed in a standing position.

しかし、搬送速度が遅いと藁束を集稈部に集束
されている排藁から離すのに時間がかかるため搬
送されている藁束が集束藁稈と干渉する時間が長
くなり集束姿勢を乱して結束ミスを誘発した。 However, if the conveyance speed is slow, it takes time to separate the straw bundles from the straw collected in the collecting culm, so the time that the transported straw bundles interfere with the collecting straw culms becomes longer and the collecting posture is disturbed. This caused a bundling mistake.

る。 This invention allows the straw bundles to be discharged and conveyed to pass through the part corresponding to the collecting culm as quickly as possible to prevent the posture of the collected straw culms from being disturbed, and also to reduce the conveying speed when the straw bundles are allowed to fall from the end of the conveyance. The purpose is to slow down the movement of the ball so that it will land in a good standing position after being released.

することができる。 As mentioned above, the present invention is a combine harvester in which a tying machine is attached to the rear of the threshing device, and a straw bundle holding conveyor is installed on the straw bundle discharge side of the tying machine to transport the straw bundles horizontally toward the harvested field. , the straw bundle clamping conveyance body is constituted by two consecutive clamping conveyance bodies, and the conveyance speed of the front clamping conveyance body facing the bundling machine is set to be high;
The conveyance speed of the subsequent holding and conveying body was set at a low speed, so that the preceding holding and conveying body could prevent the released straw bundle from being rapidly separated from the following collecting straw and disrupting the starting force of the collection. When the straw bundle is handed over to the rear holding conveyor, it is transported at a low speed, the discharge speed can be reduced, and the landing posture of the straw bundle can be made into an orderly standing posture.
