It is related to the technology that enables the planting work to be carried out .

[0002]

2. Description of the Related Art Taking a rice transplanter as an example of a seedling transplanter,
There is a machine equipped with a storage section for spare seedlings to be supplied to the seedling platform, and a seedling supply device equipped with a conveyor for supplying seedlings from a position such as a ridge to the storage section for this spare seedling. It is considered (for example, Japanese Patent Laid-Open No. 4-278006).

[0003]

Many conventional rice transplanters are equipped with a fertilizer application device for feeding fertilizer to a field near the transplanted seedlings at the same time when the seedlings are transplanted. It is also necessary to replenish the hopper for storing fertilizer with fertilizer. Further, when the seedlings are replenished to the preliminary seedling storage section, the machine body is stopped near the ridges and the like, and replenishment of the fertilizer at this time is effective in improving work efficiency.

However, since the seedlings contain water and are heavy, it is desired to automatically carry out the work for supplying the seedlings to the spare seedling storage portion by using a mechanism such as a conveyor as in the conventional example. At the same time, there is also a side that wants to automatically replenish the fertilizer to the fertilizer application device.

An object of the present invention is to reasonably configure a device that can quickly supply seedlings to a spare seedling storage portion of a machine and fertilizer to a fertilizer application device.

Located that point, its action and effects are as follows.

[0007]

According to the above feature (claim 1), when the seedling and the fertilizer are supplied, the connecting member at the tip of the conveyor mechanism is connected to the seedling supply section of the seedling transplanter, so that The relative position with the seedling transplanter will be determined, and by connecting the communication connecting member at the tip of the fertilizer transfer pipeline to the supply pipeline on the seedling transplanter side in such a state where the relative position is determined, It is possible to send seedlings from the storage section for supply seedlings to the spare seedling storage section of the seedling transplanter via the conveyor mechanism and seedling supply section, and the fertilizer from the supplementary fertilizer tank is connected to the transfer pipeline and communication. It is possible to send the fertilizer to the fertilizer storage part of the seedling transplanter via the supply section and the supply line.

That is, the present invention is provided with a seedling-feeding conveyor mechanism whose tip is connectable to the seedling transplanter, and
By providing a conveyor line along the conveyor mechanism, it is possible to easily determine the relative position between the tip of the conveyor mechanism and the seedling transplanter of the seedling transplanter to supply seedlings, and at the same time to supply fertilizer. .

According to a second aspect of the present invention, when the leading end of the conveyor mechanism is connected to the carry-in section of the seedling transplanting machine, the connecting member is fitted and connected to the member to be connected on the seedling transplanting machine side. The relative position between the tip of the mechanism and the seedling transplanter is determined, and the fertilizer transport path of the conveyor mechanism and the supply line of the seedling transplanter are in communication via the internal space of the connecting member and the concave space of the connected member. The fertilizer can be transported along this route.
