It is provided between the container and the drop guide so as to be disengaged upon operation.

The functions and effects thereof are as follows.

[For production]

The sorting tool acts on the fertilizer that is dispensed in a set amount from the dispensing device and flows in a small amount and in a large flow, thereby sorting out the powdered fertilizer and causing it to leak into the container.

The container and the drop guide are combined into an integrated article by the second fitting structure and the third locking structure, and are firmly attached to the dispensing device by the first and second locking structures and the first fitting structure. Fixed intersection. When the second locking structure is in the released state, the second locking structure can be engaged or unmated, and in conjunction with this operation, the third locking structure can be brought into the engaged or disengaged state. state and the container can be attached or removed. When the first and second locking structures are released, the first fitting structure can be fitted and unfitted, and the fall guide can be attached and detached. That is, compared to adopting a locking means in which the drop guide is fixed to the feeding device and the container is fixed only to the drop guide, the container and the drop guide can be secured with a few locking structures including only the first to third lock structures. Can be securely installed and fixed. Further, compared to forming the third lock structure to require a dedicated locking operation and locking operation, the container can be attached and detached with fewer locking operations and unlocking operations.
