Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice transplanting machine, and more particularly to a marker for a round planting which is extended to the side of the machine to maintain a constant space between the machine and ridges at the time of planting. It relates to the mounting structure.

[0002]

2. Description of the Related Art When a seedling is planted in a field using a rice transplanter, the seedling is separated from the ridge by an interval of the number of rows that can be simultaneously planted by the rice transplanter (the number of rows of the seedling table). By performing the planting operation (round planting operation) last, the traveling distance in the field at the time of the planting operation is shortened, and the hand-planting portion is eliminated, thereby improving the efficiency of the planting operation.

In order to carry out the above-mentioned planting operation, it is necessary to keep a constant distance between the body and the ridge at the time of planting. For this reason, the planting marker is attached to the side of the machine in a state where it is extended. The rice transplanter was running while the tip of the co-planting marker was along the edge of the ridge.

In a conventional rice transplanter, as disclosed in Japanese Patent Application Laid-Open No. 10-295110, a pair of left and right spare seedling stands are mounted on an airframe and planted around each spare seedling stand. A support member for supporting the marker is attached, and a turning planting marker is attached to the supporting member. A turning planting marker is provided on each of the right and left sides of the body.

[0005]

However, it is only necessary to provide the surrounding planting markers only on one of the right and left sides of the machine body. When the surrounding planting marker is provided, a pair of left and right surrounding planting markers and a pair of left and right supporting members for supporting them are required, and the number of parts constituting the rice transplanter is increased, and assembling workability is improved. It was bad.

In addition, since a special support member is used to support the surrounding planting marker, the cost is increased.

In the conventional rice transplanter described above, when the turning planting marker is not used, the turning planting marker is bent from the base end toward the rear of the machine so that the marker is arranged along the side of the machine. The rotating planting marker was housed in a retracted state, so that the worker's body could come into contact with the rotating planting marker when working on the left and right sides of the rice transplanter or when getting on or off the driver's seat. Therefore, there is a possibility that the surrounding planting marker may be damaged.

[0008]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a rice transplanter having a turning planting marker which is extended to the side of the fuselage and used to maintain a constant distance between the fuselage and the ridge at the time of planting. In the above, the frame component constituting a part of the body frame was also used as a support member for the surrounding planting marker.

In addition, the surrounding planting marker can be housed inside the frame structure supporting the surrounding planting marker.

[0010] Further, the frame structure supporting the surrounding planting marker is extended in the left-right width direction of the machine body, and the surrounding planting marker is configured to be attachable / detachable to both left and right end portions of the frame body.

Further, the surrounding planting marker is configured to be extendable and contractible.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION A marker mounting structure for a planting around a rice transplanter according to the present invention is horizontally extended between a pair of left and right main pipes extending in the front-rear direction and front ends of both main pipes. An airframe is constructed from a front end pipe, and a planting marker can be mounted around a front end pipe constituting a part of the airframe.

As described above, since the frame constituting part of the body frame is also used as a support member for the surrounding planting marker, it is necessary to separately provide a supporting member for supporting the surrounding planting marker. Thus, the number of components constituting the rice transplanter can be reduced, and the manufacturing cost can be reduced and the assembling work can be facilitated.

In particular, by making it possible to store the turning planting marker inside the front end pipe, the turning planting marker can be made compact when the turning planting marker is not used. This eliminates the risk that the body of the individual will come into contact with the surrounding planting marker, thereby preventing the surrounding planting marker from being damaged.
