Attachment structure of marker for planting around rice transplanter

Technical field

The present invention relates to a rice transplanter and, more particularly, to a structure for attaching a turning plant marker that is extended to the side of the fuselage and used to maintain a constant gap between the fuselage and the ridge at the time of planting. is there.

Background art

When planting seedlings in a field using a rice transplanter, plant the seedlings in the field separated from the ridges by the number of rows that can be planted simultaneously by the rice transplanter (the number of rows of the seedling table). By performing the work (planting work) at the end, the traveling distance in the field during the planting work was shortened and the hand-planting part was eliminated, thereby improving the efficiency of the planting work.

In order to carry out the above-mentioned round planting work, it is necessary to maintain a constant distance between the aircraft and the ridge at the time of planting. The rice transplanter was running with the tip of the surrounding planting marker 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 mounting tables are mounted on the body frame, and each preliminary application is performed. A support member for supporting the surrounding planting marker was attached to the platform, and the surrounding planting marker was attached to the supporting member. The surrounding planting marker was provided on each of the left and right sides of the fuselage. However, it is only necessary to provide the surrounding planting markers on either one of the left and right sides of the fuselage. This required a pair of left and right recirculating planting markers and a pair of left and right supporting members to support them, increasing the number of components that make up the rice transplanter, resulting in poor assembly workability.

In addition, the use of a special support member to support the surrounding planting marker causes a high cost.

Also, 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, and is along the side of the machine. Since the rotating planting marker was configured to be housed in a state where it was aligned, the worker's body and the rotating planting marker could be moved when working on the left and right sides of the rice transplanter or when getting on and off the driver's seat. There was a risk of damage to the surrounding planting marker due to contact. Disclosure of the invention

In view of the above, according to the present invention, a part of the machine body frame is configured in a rice transplanter having a turning planting marker which is extended to the side of the machine body and used to maintain a constant distance between the machine body and the ridge at the time of planting. Around the frame structure to be used as a support member for the planting marker.

In addition, it is now possible to store the surrounding planting marker inside the frame structure that supports the surrounding planting marker.

In addition, the frame that supports the surrounding planting marker is extended in the left-right direction of the fuselage, so that the surrounding plant can be attached to and detached from both left and right ends of the frame.

In addition, the surrounding planting marker is configured to be stretchable. The marker mounting structure for surrounding planting of a rice transplanter according to the present invention comprises a pair of left and right main pipes extending in the front-rear direction and a front end pipe extending laterally in a lateral direction between the front ends of the two main pipes. And a marker for planting around the front end pipe that forms a part of the airframe.

As described above, since the frame structure constituting a part of the body frame is also used as a support member for the surrounding planting marker, there is no need to separately provide a supporting member for supporting the surrounding planting marker. The number of components that make up the rice transplanter can be reduced, and manufacturing costs can be reduced and assembly work can be simplified.

In particular, by making it possible to store the turning planting marker inside the front end pipe, when the turning planting marker is not used, the turning planting marker can be made compact, and the worker can move up and down the rice transplanter. This eliminates the risk that the body of the patient will come into contact with the surrounding planting marker, thereby preventing damage to the surrounding planting marker.
