Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice transplanter with a fertilizer application in which a fertilizer application device is mounted above a planting mechanism for taking out and planting seedlings from the lower end of a seedling stand in the seedling planting device.

[0002]

2. Description of the Related Art In the rice transplanter with a fertilizer application described above, conventionally, the fertilizer application is arranged in a fixed position by a support frame standing upright from a planting transmission case.

[0003]

In the above-mentioned conventional structure, since the tall fertilizer application device is present on the rear upper side of the seedling stand over almost the entire planting width, the planting work is completed in a certain field, for example. When performing a work of taking out the placed seedlings that are slightly left on the seedling stand later, this fertilizer application is a hindrance, which makes the work difficult. The present invention eliminates the above-mentioned problems, and by reasonably configuring the separation structure of the fertilizer downflow route accompanying the structural improvement therefor, while facilitating the movement of the fertilizer application device, mud soil for the fertilizer downflow route The purpose is to effectively prevent the intrusion of water and moisture.

[0004]

According to a characteristic configuration of the present invention, in the rice transplanter with a fertilizer application described at the beginning, the fertilizer application work on the lower side is performed on a support rail erected from a frame of the seedling planter. The upper and lower positions of the fertilizer application are supported so that the vertical position can be freely changed, and a separable connecting portion is provided in the fertilizer feeding path of the fertilizer applicator. At the bottom edge of the boot, elastically deformable lips are formed on the periphery of the lower end of the boot to cover the upper side of the planting mechanism and the outer surface of the fertilizer flow pipe with almost no gap.

[0005]

[Function] When the fertilizer application is set to the work position on the lower side, the downflow path between the feeding mechanism and the field scene for supplying the fertilizer is shortened, and the fertilizer can be smoothly fertilized without causing clogging. When taking out the seedlings that are a little left on the seedling stand after the work is completed, by moving the fertilizer application to the upper retracted position, the outside of the lower part of the seedling stand is largely opened, making it easy to take out the seedlings. It will be possible to do. Moreover, in order to smoothly slide the fertilizer application up and down, it is necessary to separate the long-flowing fertilizer flow-down path in the middle, but at the separation portion, the lower end periphery of the boot that constitutes the lower end opening on the fertilizer application side The elastically deformable lip part formed on the outer surface of the fertilizer falling pipe and the mudguard cover that covers the upper side of the planting mechanism is almost separated without gaps, so that the fertilizer application is frequently separated and connected as the fertilizer application slides. Even if the relative positional relationship is slightly different at a certain position, and there is a dimensional error at the time of connection, the error can be absorbed by the elastic deformation and the sealing performance can be reliably maintained.

[0006]

[Effects of the Invention] Therefore, it is possible to perform a smooth fertilization work in which fertilizer clogging does not easily occur during seedling planting work, but the removal of the remaining seedlings on the seedling stand after the work interferes with the tall fertilizer application device. It can be done easily without being done. Further, even when the fertilizer flow-down path separated by the movement of the fertilizer applicator is re-connected, the outer side of this connection point is covered by the boot, and the elastically deformable lip portion allows the peripheral edge to be in close contact without any gap. Sealed to prevent rainwater and mud from entering the fertilizer flow path, and even if frequent connection / separation work is performed, it is possible to prevent gaps due to dimensional errors and maintain sealing performance for a long time. It became a thing.
