Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to install a fertilizer application device above a planting mechanism for taking out and planting seedlings from the lower end of a seedling stand in a seedling planting device, and a fertilizer feeding mechanism for this fertilizer application device. The present invention relates to a rice transplanter with a fertilizer application, in which the rotating part of the planting mechanism is interlockingly linked via a rod.

[0002]

2. Description of the Related Art In the rice transplanter with a fertilizer application described above, the fertilizer application is conventionally arranged in a fixed position by a support frame erected from a planting transmission case, as disclosed in Japanese Utility Model Laid-Open No. 3-22616. It was configured to do.

[0003]

However, in the above-mentioned conventional structure, since a plurality of tall fertilizer application devices are arranged above the seedling planting site for each row, for example, work in a certain field is not possible. When the seedlings left on the seedling stand were taken out at the end of the operation, the fertilizer application was a hindrance, which made the work difficult to perform, and there was room for improvement. An object of the present invention is to make it possible to easily take out the remaining seedlings remaining on the seedling stand and prevent the harmful effects of such improvement.

[0004]

A characteristic construction of the present invention is that in the rice transplanter with a fertilizer application described at the beginning, the fertilizer application work is performed on a lower side of a support rail erected from a frame of the seedling planter. It is configured such that it is supported so that the vertical position can be changed between the position and the position retracted upward, and the connecting portion of the rod to the planting mechanism is detachably configured.

[0005]

[Function] A fertilizer application device can be attached to the work position in the upper part near the planting mechanism to effectively perform fertilizer application, and when a small amount of the remaining seedlings is to be taken out from the seedling stand after the planting work is completed, By retracting the device to a higher position along the support rail, the outer side of the lower end of the seedling stand is largely opened, and the seedling removal work can be easily performed. Further, since the connecting rod for driving the fertilizer feeding mechanism for fertilizing by interlocking with the power of the planting mechanism is configured to be disconnected at the connecting portion on the side of the planting mechanism, the fertilizer applying device is moved to the upper retracted position. When the seedlings are removed from the seedlings, there is no outward protrusion on the planting mechanism side, and the seedlings are not supported.

[0006]

As a result, in the planting work state, the fertilizer application device is brought as close as possible to the planting mechanism, and the fertilizer can be effectively supplied to the place as close as possible to the planted seedlings with a small time delay. It has become possible to provide a product that can efficiently and easily take out the remaining seedlings after the work is completed. Also, the feeding mechanism of the fertilizer application can be driven with a simple structure by effectively utilizing the power of the planting mechanism without using a dedicated motor, etc. It can now be set to a state without bearings. Moreover, since the connecting member does not remain on the planting mechanism side, the planting mechanism can be operated even when the fertilizer application is set to the upper retracted position, and maintenance work such as adjustment of the seedling removal amount can be performed. There are also advantages.
