れる穀粒回収装置に関する。[Detailed Description of the Invention] [Industrial field of application] The present invention can increase the substantial capacity of the grain storage tank during the mowing work, and the width of the grain storage tank can be increased when not working such as on the road. In order to make it compact, it is mounted on a combine container etc. that has an auxiliary tank for increasing the amount of stored grain that can be switched between one side of the grain storage tank that extends laterally outward and the other that retracts to the tank side. The present invention relates to a grain collection device used.

ンクを下端支点で枢支して横外側方に張出し可能な構造
を採っており、これら姿勢の切換えは作業者が直接補助
タンク側の把手を持って行っていた（例えば実開昭59-3
1842号公報）。In this type of grain collecting device, as a structure capable of switching the auxiliary tank between the overhanging posture and the retracted posture, conventionally, a structure is adopted in which the auxiliary tank is pivotally supported at the lower end fulcrum and can be laterally outwardly extended. However, the operator had to switch between these postures by directly holding the handle on the auxiliary tank side (see, for example, SAIKAI Sho 59-3
1842 publication).
この場合には直接補助タンクに姿勢切換のための把手等
の操作具を設けなければならない為に、前記公報（実開
昭59-31842号第２図）で示すように、補助タンクの横側
面にならざるを得ないが、この把手の取付位置が地上高
より高い場合には踏台等を用意しなければならない操作
上のわずらわしさがあり、かといって把手の位置を下げ
た場合には把手取付位置が補助タンクの下端枢支点に近
くなって、姿勢切換に要する操作力が大きくなる欠点が
ある。In this case, since the auxiliary tank must be directly provided with an operation tool such as a handle for changing the posture, as shown in the above-mentioned official gazette (Act No. 59-31842, Fig. 2), the lateral side surface of the auxiliary tank However, if this handle is mounted higher than the ground level, there is some operational difficulty in preparing a step, etc., but if the handle is lowered, the handle There is a drawback in that the mounting position becomes closer to the pivotal fulcrum of the lower end of the auxiliary tank, and the operation force required for posture switching becomes large.
本考案の目的は切換操作機構に合理的な改造を加えて姿
勢切換を容易に行えるものを提供し乍ら、その切換操作
機構を簡素化できるものを提供する点にある。It is an object of the present invention to provide a switching operation mechanism which can be easily changed in posture by making a reasonable modification to the switching operation mechanism and to provide a switching operation mechanism which can be simplified.

パーが引退姿勢になる。又、補助タンクを張出し状態に
切換えるには、ハンドルを反対向きに回転操作すればよ
い。In other words, when the handle is rotated while the auxiliary tank is overhanging, the base end of the top plate rotates together and the top end of the top plate in the extended state switches to the refraction posture with respect to the base end. During this refraction process, the auxiliary hopper is pulled to the base end and assumes the retracted posture. To switch the auxiliary tank to the extended state, the handle may be rotated in the opposite direction.
