2. Description of the Related Art Conventionally, a left and right transmission case has been extended laterally from a feed case, and a plurality of rows of planting cases have been extended from the left and right transmission cases to the rear by bypassing below the seedling stand. A seedling planting mechanism for cutting and planting seedlings from the seedling platform is provided at the rear end of the mounting case, and the seedling plant, the planting case, and the seedling planting mechanism constitute the seedling planting device, and the rear of the seedling platform. A fertilizer applicator equipped with a storage hopper and a payout mechanism is provided, and the payout mechanism and the seedling planting mechanism are linked to each other so that power can be transmitted from the planting case to the fertilizer applicator. In order to perform maintenance work with good workability, the fertilizer application device is configured to be horizontally movable around the vertical axis with respect to the seedling planting device, and is separated from the seedling table in a laterally open state from the installation position corresponding to the work. Was taken (actual Kaihei 2-3 612 JP).

[0003]

However, since the planting case is connected to the feed case through the transmission case, only the fertilizer application device is opened laterally to open the seedling mounting surface of the seedling mounting table. Since it is best to use a configuration that separates it from the seedling placing table, the planting case remains below the seedling placing table even if only the fertilizer application device is set to the sideways open state. When removing the seedlings remaining at the lower end, there was a planting case at the feet, so there were restrictions on the work posture, and workability was poor. An object of the present invention is to provide a device that can smoothly perform maintenance work on the lower end of the seedling table by simply changing the transmission system from the feed case to the planting case and the fertilizer application device.

[0004]

According to a characteristic configuration of the present invention, the fertilizer application device is attached to the fertilizer application device so that power can be transmitted, and the fertilizer application device and the plant application case device are integrally installed to correspond to a working condition. It is configured so as to be movable between a position and a standby position separated from the seedling mounting table, and its function and effect are as follows.

[0005]

In other words, by adopting a mode in which power is supplied to the planting case from the fertilizer application device, the planting case can belong to the fertilizer application device in a state of being separated from the seedling placing table. The case can be separated from the seedling table together with the fertilizer application device.

[0006]

Therefore, when the fertilizer applicator is separated from the seedling placing table, the planting case is also separated from the seedling placing table, and the lower part of the seedling placing table is also in an open state. You can do it.
