Description of the Related Art In the above-mentioned structure, by placing the storage hopper and the feeding mechanism in the non-working position, the seedling placing surface of the seedling placing table can be greatly opened, and the work around the seedling placing table, especially , When carrying out work around the lower end of the seedling placing surface such as processing a small amount of seedling remaining at the lower end of the seedling placing surface, which is difficult to reach from the driving control unit like in the case of a riding type rice transplanter, Since the worker can approach the seedling mounting surface and perform maintenance work, the work can be performed easily and quickly. As an effect of such an effect, conventionally, there has been one in which the fertilizer application device is pivotally moved laterally around the longitudinal axis with respect to the seedling planting device to change the position to the non-working position (Japanese Patent Laid-Open No. HEI 2). -39612).

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to improve the easiness of position changing work by improving the conventional structure showing only the basic structure capable of changing the position of the fertilizer application to a non-working position away from the seedling table. The point is to provide the thing which can be surely positioned at the working position while being able to obtain.

[0004]

According to a feature of the present invention, a biasing mechanism for biasing the storage hopper and the feeding mechanism upward is provided, and the storage hopper is resisted against the biasing force of the biasing mechanism. And a feeding mechanism, a lock mechanism for fixing the work mechanism to the working position is provided, and the lock mechanism is
A movable member that moves integrally with the storage hopper and the feeding mechanism, a lock operation tool that is in a locked posture by downward swinging, and an engagement portion that is attached to one of the lock operation tool and the movable member and is the other. It is composed of a linking arm that is hung over the wire, and its function and effect are as follows.

[0005]

The function of moving the work position to the non-work position will be described. When the lock operation tool is lifted to release the lock and the linking arm is disengaged from the engaging portion, the storage hopper, the feeding mechanism and the like to be moved are floated by the urging mechanism.
The floating storage hopper or the like is moved toward the non-working position. It is possible to perform maintenance work on the seedling placing surface of the seedling placing table and the like in a state where it reaches the non-working position. To return the storage hopper to the work position, return the storage hopper to the predetermined position, and when the predetermined position is reached, hang the linkage arm over the engaging part and swing the lock operation tool downward to position the storage hopper at the work position. it can.

[0006]

Therefore, it is possible to position the fertilizer applicator at the proper predetermined position at the working position, and to suppress the positional fluctuation due to the locking action of the lock operating tool, and also in terms of the operating surface for the lock operating tool. It is possible to switch between the locked state and the unlocked state simply by swinging the lock operation tool up and down, and since the operation direction is set to the up and down direction, even if the biasing force acts upward, Since it is an operation in the direction in which it operates, downward operation is possible with a comparatively light operating force, and when unlocking, the urging force of the urging mechanism is used as the operating force for the upward operation of the lock operation tool. Yes, this can also be done with a light operating force,
In any case, the lock operation tool can be easily operated. Further, since the biasing force of the biasing mechanism acts on the storage hopper when moving the storage hopper,
This has the effect of reducing the load when moving and thus reducing the load of movement.
