Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling stage on which seedlings are placed and reciprocated and moved laterally, and seedlings placed on the seedling stage with the lateral movement of the seedling stage. And a planting mechanism for planting, and a multi-row fertilizer device for feeding fertilizer to the field at the time of planting operation is arranged on the side of the seedling mounting surface of the seedling mounting table. More specifically, the present invention relates to a technique for reducing the size of a seedling mounting table in a lateral direction during storage.

[0002]

2. Description of the Related Art Conventionally, as a seedling planting apparatus configured to reduce the size of a seedling mounting table in the width direction at the time of storage as described above, there is one disclosed in Japanese Patent Application Laid-Open No. Hei 5-7407. In this conventional example, the folded portions at both ends of the seedling rest are connected to the center seedling rest via a link mechanism, and the folded portions at both ends are suspended from the center seedling rest at the time of storage. By switching to the posture, the dimension in the width direction can be reduced. In this conventional example, the seedling planting device is not provided with a fertilizer application device.

[0003]

Considering the case where the folded portions at both ends are switched to the hanging posture, the seedling mounting table has a gentle curved surface in side view. Even if an attempt is made to enable folding by arranging a simple hinge with respect to the dividing plane, the folding plane cannot be folded due to contact between the dividing planes at the time of switching the posture of the folding unit with such a hinge arrangement As shown in the conventional example, a structure is adopted in which the posture can be switched in a state where the divided surfaces are largely separated from each other by using a complicated link mechanism having a plurality of pivot shafts. ing.

[0004] However, in the case where the attitude of the folded portion can be switched using a link mechanism having a complicated structure, not only the link mechanism having a complicated structure is required as described above, but also the number of parts is increased. There is room for improvement because the link mechanism becomes large in order to enable the switching of the orientation of the folded portion which is easy and large and which tends to be heavy.

Therefore, it is conceivable to support the separated seedling mounting portion on the seedling mounting surface side of the central seedling mounting portion. However, in the case where the fertilizer is provided on the side of the seedling mounting surface, the separation is hindered by the fertilizer. It will not be possible to support the seedling mounting part.

SUMMARY OF THE INVENTION An object of the present invention is to provide a seedling mounting apparatus having a fertilizer application device on the side of a seedling mounting surface of a seedling mounting table, in which the width of the seedling mounting table is reduced without employing a complicated and large-sized structure. The point is that the obtained seedling planting device is rationally configured.

[0007]

According to a first aspect of the present invention, as described at the outset, a seedling mounting table on which seedlings are placed and which reciprocally moves laterally, and a lateral movement of the seedling mounting table. And a planting mechanism that cuts out seedlings placed on the seedling mounting table and places them in a field scene, and is configured for a plurality of lines, and feeds fertilizer to the field at the time of planting operation. In the seedling mounting device of a riding type rice transplanter arranged on the side of the seedling mounting surface of the seedling mounting, the seedling mounting, the seedling mounting portion at the center of the seedling mounting,
It is composed of the left and right seedling mounting portions that are configured to be freely switchable between a connected state and a separated state with respect to the seedling mounting portion, and is separated from the seedling mounting surface side of the central seedling mounting portion. A support portion for supporting the seedling placing portion, wherein the entire fertilizer application device, or a part of the fertilizer application device, is displaced rearward from the working position where the seedling placing surface is approached, and The space for allowing the support of the seedling placing portion with respect to the portion is provided via a position switching means that can be switched to a retracted position formed on the side of the seedling placing surface, and the operation is as follows. .

According to a second feature of the present invention (claim 2), the support portion is constituted by a support member formed at an upper position and a lower position on the side of the seedling mounting surface in the seedling mounting portion at the center position. The effect is as follows.

[0009] A third feature of the present invention (claim 3) is that the position switching means is displaced toward the seedling placing surface side by swinging around the axis, and is separated rearward from the seedling placing surface. It is composed of a frame that can be switched between the posture and the posture. The whole fertilizer or a part of the fertilizer is supported on the frame. The operation is as follows.

[0010] A fourth feature of the present invention is that the retracting posture of the frame is a first retracting posture that allows the support portion to support the separated seedling mounting portion with respect to the support portion, and further largely rearward. And a second retreat position allowing manual removal of the seedlings from the seedling mounting table.

A fifth feature of the present invention (claim 5) is that the frame or the fertilizer is held at at least two positions, a working position and a first retreat position, by the frame. It has a locking means that acts, and its operation is as follows.

According to the first feature, when the lateral size of the seedling mounting table is reduced, the entire fertilizer or a part of the fertilizer is set to the retreat position by the position switching means. The seedling rests at the left and right ends are separated from the central seedling rest, and the separated seedling rests are supported by the support portion, so that the separated seedling rests are obstructed by the fertilizer. It is supported at a position on the side of the seedling mounting surface of the central seedling mounting part without any. In other words, this feature does not switch the postures of the seedling placing portions at both ends while supporting the seedling placing portion on the center side as in the conventional example, but completely shifts the seedling placing portions at both ends from the central seedling placing portion. Separated and supported on the central seedling mounting part, not only does not require a complicated member such as a link mechanism, but also has a reasonable supporting posture, and the fertilizer is configured to be adjustable in the front-back direction. Therefore, for example, the fertilizer applicator protrudes rearward during work as compared to a case where the central seedling mounting section and the fertilizer applicator are arranged far apart so that the separated seedling mounting section can be supported by the central seedling mounting section. Not even.

According to the second feature, even when the separated seedling mounting portion is supported on the side of the seedling mounting surface of the central seedling mounting portion via the support member, the support is provided from the closest central seedling mounting portion to the support. It is possible to support the seedling placing portion in a reasonable posture with a simple structure using a member having a short dimension, such as by projecting a member having a shape.

According to the third feature, since the position of the entire fertilizer or a part of the fertilizer is switched by switching the posture by swinging the frame member, for example, the position switching means using a sliding type frame member. As compared with the structure of the above, the stiffness hardly occurs and the fertilizer can be smoothly switched between the working position and the retreat position, though the structure is simple.

According to the fourth feature, when the separated size of the seedling mounting portion is supported on the side of the seedling mounting surface of the central seedling mounting portion to reduce the lateral dimension of the seedling mounting base, the fertilizer applicator is required. It is sufficient to set the fertilizer to the first evacuation position, and if the seedlings are to be artificially removed from the seedling mounting table at the time of work, it is sufficient to set the fertilizer application device to the second evacuation position. Even when the lateral dimension is reduced, the fertilizer applicator does not protrude greatly backward.

According to the fifth feature, the entire fertilizer or a part of the fertilizer can be held at the working position and the first retreat position by the locking means, and the separated seedling mounting portion is placed at the center of the seedling. Even when the fertilizer is placed behind the loading part and transported, the fertilizer applicator does not come into contact with the separated seedling loading part, and the fertilizer can be stably held at an appropriate position during work.
