Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a rice transplanter with a fertilizer application, which comprises a seedling stay for suppressing floating of seedlings on a seedling placing table, and a fertilizer applying device main body is arranged on the seedling placing surface side of the seedling placing table. Regarding

[0002]

2. Description of the Related Art In the above rice transplanter, when seedlings are supplied to the seedling placing table, if the seedling stay is separated from the seedling placing surface of the seedling placing table, the seedlings can easily enter and the seedlings can be easily fed. Further, when taking out the seedlings remaining on the seedling placing table, it is necessary to remove the seedling stay from the lower end side of the seedling placing table to open the upper part of the lower end side of the seedling placing table. Therefore, in the past, for example, Japanese Patent Laid-Open No. 6-
As shown in Japanese Patent No. 327311, the upper end side of the seedling stay can be connected to the support column of the seedling mounting table via a swing link, and the lower end side can be connected to or separated from the support portion of the seedling mounting table. By moving the seedling stay with the lower end side removed from the support part to the upper end side of the seedling placing table by the action of the swing link, the seedling stay is supported on the seedling placing table while the seedling placing table is supported. In some cases, the lower end of the table was opened, and the distance between the seedling mounting surface of the seedling mounting table and the seedling stay became wider than during the work.

[0003]

In the above-described conventional technique, even if the seedling stay is moved to the upper end side of the seedling placing table and the operation is released, the whole of the seedling placing table on the seedling placing table is relatively large. It was located near the face side. Moreover, the lower end side of the seedling mounting table was not fully opened. For this reason, when supplying seedlings, it is difficult to reach because the seedling stays are obstructed even when trying to support the lower end side of the seedlings to be slid from the upper end side of the seedling mounting table. For large seedlings, it is easy to get caught on the bottom edge of the seedling stay.
Work such as seedling supply and seedling removal was not yet easy enough. An object of the present invention is to provide a rice transplanter equipped with a fertilizer application, which can sufficiently easily perform operations such as seedling supply and seedling removal performed by switching the seedling stay to the operation-released state.

[0004]

The constitution, operation and effect of the invention according to claim 1 are as follows.

[Configuration] In a rice transplanter equipped with a fertilizer application, the upper and lower ends of a seedling stay that suppresses the floating of seedlings on the seedling mounting table are connected to the seedling mounting table so as to be pivotally and separably operable, and to be used as a fertilizer tank. A fertilizer application main body that has a feeding device that feeds fertilizer from the fertilizer tank and that supplies fertilizer to the fertilizer application from the feeding device, at the seedling placing surface side of the seedling placing table, at a fixed portion of the seedling planting device and the fertilizing application. Through a four-link mechanism having a swinging link that connects to the device body, the work position and a non-working position located on the opposite side of the work position to the non-working position can be positionally fixed. It is connected to the department.

[Operation] When the upper end side of the seedling placing table is opened to perform work such as seedling replenishment, the fertilizer applying apparatus main body is switched to the non-working position by the four-link mechanism so that the fertilizer applying apparatus main body and the seedling placing table are separated from each other. The spacing between the seedling stays is wider than when working, the upper end side is disengaged from the seedling stand, and the lower end side remains connected to the seedling stand. Let Then, because of the wide spacing between the fertilizer application main body and the seedling placing table, the seedling stay can be largely separated from the seedling placing table toward the fertilizer applying apparatus main body, and the upper part of the seedling placing table can be largely opened. In addition, depending on the movement stroke of the fertilizer application body, the upper end of the seedling stay may be moved toward the fertilizer application body more than the lower end so that the fertilizer application body receives the seedling stay, and the seedling stay is attached to the seedling mounting table side by its own weight. Can be supported so as not to return.

When the lower end side of the seedling placing table is opened and the work such as taking out the seedling is performed, the fertilizer applying apparatus main body is switched to the non-working position by the four-link mechanism so that the interval between the fertilizer applying apparatus main body and the seedling placing table is changed. Make it wider than when working, and the lower end will come off the seedling stand,
The seedling stay whose upper end side is still connected to the seedling mounting base is rocked upward from the seedling mounting base so that the upper end side serves as a pivot. Then, due to the wide gap between the fertilizer application main body and the seedling mounting table, the lower end side of the seedling stay does not hit the fertilizer application main body and is not regulated to be raised, or even when the fertilizer application main body is hit and regulated to rise, the fertilizer application body is in the working position. The rising stroke can be made larger than it is, and the upper part of the seedling stand can be opened greatly.

[Effect] As a working position of the main body of the fertilizer application,
Set the position where the fertilizer applicator main body comes as close as possible to the seedling mounting table to prevent or reduce the length of the fertilizer applicator main body, which makes it possible to run advantageously, and the seedling stay works. When performing work such as supplying seedlings or removing seedlings in the released state, it is possible to work with advantage such that the seedling stay is widely separated from the seedling mounting table and the hand can be easily attached to the seedling, or the seedling is hard to be caught by the seedling stay. It became so. Further, the nursery stay was supported on the main body of the fertilizer application so as not to return to the side of the nursery stand, and it was possible to work easily without the need for the labor.

The structure, operation and effect of the invention according to claim 2 are as follows.

[Operation] By applying an operating force in the shortening direction to the seedling stay and elastically deforming it at the bent portion, the upper end side or the lower end side of the seedling stay is detached from the stay supporting portion to release the seedling stay operation. The seedling stay can be returned to the working state by connecting the attaching portion to the stay supporting portion.

[Effect] Either the upper end side of the seedling stay is separated from the seedling mounting table to perform seedling supply or the like, or the lower end side of the seedling stay is separated from the seedling mounting table to perform seedling removal or the like. In the case of (3), the seedling stay could be easily and quickly put into the released state for efficient work, and the seedling stay could be returned to the activated state easily and quickly.

The structure, operation, and effect of the invention according to claim 3 are as follows.

[Constitution] In the constitution of the invention according to claim 1, the stay supporting portion on the seedling mounting table side, to which the mounting portions on the upper end side and the lower end side of the seedling stay are connected, is formed in a fitting shape, and the seedling stay is formed. A bent portion is provided, and the attachment portion is connected to and separated from the stay support portion while elastically deforming the seedling stay in the shortened direction at the bent portion.

[Operation] By applying an operating force in the shortening direction to the seedling stay and elastically deforming the bent portion, either the upper end side or the lower end side of the seedling stay is detached from the stay supporting portion to fix the seedling stay. It can be brought into the operation-released state or the seedling stay can be returned to the operation state by connecting the attachment portion to the stay support portion.

[Effect] In any case of performing work such as seedling supply with the upper end side of the seedling stay away from the seedling placing table, or performing work such as seedling removal with the lower end side of the seedling stay away from the seedling placing table. In addition, the seedling stay can be easily and quickly put into the released state for efficient work, and the seedling stay can be easily and quickly returned to the operating state.

The structure, operation, and effect of the invention according to claim 4 are as follows.

[Structure] In the structure of the present invention according to claim 1, 2 or 3, the stay supporting portion to which the mounting portion on the upper end side of the seedling stay is connected is mounted on the seedling mounting table in a height adjustable manner.

[Operation] Even if the thickness of the bed soil or the foliage of the seedlings changes, the mounting height of the stay support portion is adjusted to narrow the distance between the seedling mounting surface of the seedling mounting table and the seedling stay. Function of the seedling stay so that the seedling stay does not hit the seedling too strongly and the spacing between the seedling mounting surface of the seedling mounting table and the seedling stay becomes wide so that the suppression of seedling floating by the seedling stay cannot be obtained. You can adjust the condition. In addition, at the time of work, the stay support part can be adjusted to a low mounting position for work so that the spacing between the seedling placement surface of the seedling placement table and the seedling stay is appropriate and the seedling floating is suppressed appropriately. At this time, the stay support portion can be adjusted to a higher mounting position than during the work, and the distance between the seedling mounting surface of the seedling mounting table and the seedling stay can be widened so that the seedlings can easily enter.

[Effect] The seedling stay can be appropriately operated regardless of changes in the properties of the seedlings. In addition, the seedling stay can be easily supplied by raising the seedling stay while supplying the seedling while properly operating the seedling stay during the work.
