The second cart is equipped with a stirrer (rod) that is inserted into the grain storage tank and stirs the grains, and the first and second carts are moved in the front-rear and left-right directions, respectively. While moving, the stored grain in the grain storage tank is stirred by the stirring tool.

[0003] In particular, when the paddy is additionally fed, this device is evacuated to a position avoiding the paddy inlet in the grain storage tank so that the first trolley does not hit the paddy and stopped until the paddy is finished. It is configured to let.

[0004]

In such a conventional apparatus, since the stirring tool is stopped on the wall side at the end of the grain storage tank, only the portion into which the paddy is put accumulates in a mountain shape. Therefore, as soon as you stop feeding the paddy and start stirring, the stirrer may become buried in the pile or a sudden load may be applied to the bearing of the stirrer, causing trouble. there were.

Further, if the paddy is fed for a long time with the agitator stopped, even if the paddy is sufficiently ventilated, the drafting effect is reduced and the quality of the paddy is deteriorated. There was a problem of connection. In particular, if additional paddy is added on top of the paddy that has undergone primary drying, and if the dry air is introduced from below the grain storage bottle and the dry wind is applied to the paddy, the dry air in the mountainous area becomes poor. As a result, only that part may have a higher water content than the other parts, which causes a problem that uneven water content occurs in the dried grain in the grain storage bottle.
