とうもろこし植物体にあっては、圃場によって異なる植付け条間で植え付けられることが多々あり、デバイダが一定位置に配備された収穫前処理装置の場合、植付け条間によっては、機体横端のデバイダとその前方に位置するとうもろこし植物体とが機体前後方向視で重なるとか、これに近い位置関係になり、デバイダがとうもろこし植物体の株元に突っ込みやすいとか、突っ込みの発生を回避するよう注意深く監視しながら機体操縦せねばならない問題があった。
上記した従来の技術を適用して、デバイダの先端側を機体横方向に位置変更できるよう構成し、植付け条間が異なる場合、デバイダの先端側をとうもろこし植物体の横外側を移動していくように横外側に位置変更することによって、上記した問題の発生を回避し、そして、デバイダの先端側を極力内側に位置するように位置変更することによって、デバイダの横外側への突出を抑制することが考えられる。
しかし、従来の技術を適用した場合、デバイダを回動自在に支持させることによって、デバイダの先端側を機体横方向に位置変更するものだから、デバイダの先端側を横外側に位置変更した際、デバイダの先端が横外側に移動していることに加え、横外側に移動した先端と先端側を機体内側に位置変更した際のデバイダの先端とが同じ又はほぼ同じ機体前後方向位置に位置することにより、デバイダの先端側を後方から見通し難くなりがちであった。 Corn plants are often planted between different planting lines depending on the field, and in the case of a pre-harvest treatment device in which the divider is deployed at a fixed position, depending on the planting line, the divider and its The corn plant that is located in front of it overlaps in the longitudinal direction of the aircraft, or it is close to this, and the divider is easy to plung into the corn plant stock or carefully monitor to avoid occurrence of plunging the aircraft There was a problem that had to be controlled.
Applying the above-mentioned conventional technology, the tip side of the divider can be repositioned in the horizontal direction of the fuselage, and when the planting lines are different, the tip side of the divider is moved on the lateral side of the corn plant. By changing the position to the laterally outer side, the occurrence of the above-mentioned problems can be avoided, and by changing the position of the tip of the divider so that it is located inside as much as possible, the protrusion of the divider to the laterally outer side is suppressed. Can be considered.
However, when the conventional technology is applied, the divider tip is pivotally supported to change the position of the tip of the divider in the lateral direction of the fuselage. Therefore, when the tip of the divider is changed to the lateral outer side, the divider is changed. In addition to the fact that the tip of the tip is moved laterally outward, the tip of the divider that is moved laterally and the tip of the divider when the tip is repositioned to the inside of the fuselage is located at the same or substantially the same longitudinal position of the fuselage. The end of the divider tends to be difficult to see from behind.
