しかしながら、上記特許文献１に記載された技術では、搬送筒の回動位置を摩擦力で保持するものであるため、この搬送筒の姿勢が不安定となり、排出作業中に搬送筒の姿勢が変わって排出位置がずれ、穀粒が地面にこぼれて損失となる欠点がある。 However, in the technique described in Patent Document 1, since the rotation position of the transport cylinder is held by a frictional force, the posture of the transport cylinder becomes unstable, and the posture of the transport cylinder changes during the discharging operation. As a result, the discharge position is shifted, and the grains are spilled on the ground, resulting in loss.

また、刈取走行中や路上走行中に、起立姿勢に格納していた搬送筒が、機体の振動によって機体外側方へ回動し、障害物に干渉して破損しやすくなる欠点がある。
この発明は、穀粒排出作業において搬送筒の姿勢を安定させて穀粒の損失を低減すると共に、走行中において搬送筒の格納姿勢を安定させて破損を防止することを目的としたものである。 In addition, there is a drawback that the conveying cylinder stored in the standing posture is rotated outward by the vibration of the airframe during the cutting and running on the road, and is easily damaged by interference with the obstacle.
