Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice transplanter in which a traveling machine body is provided with a planting part having a planting claw, and a seedling is planted in a paddy field by the planting claw of the planting part.

[0002]

2. Description of the Related Art Heretofore, as a seeder planting machine of this type, as shown in, for example, Japanese Utility Model Laid-Open No. 62-99917, a rotary shaft is installed in front of a planting portion having a planting claw provided on a traveling machine body. A foreign matter pushing body formed by providing a dish-shaped blade curved in an arc shape on the outer periphery is arranged so as to extend in the width direction of the planting portion, and the foreign matter in front of the planting portion is rotated by the blade by rotation of the pushing body. Embedded in the paddy field so that it can be planted without pushing out foreign matters due to the float, or in front of the planting part provided on the traveling machine body, extending in the width direction of the planting part and provided with spiral blades on the outer periphery. It is known that a spiral rotor is arranged, and the spiral blades of the spiral rotor scratch the front position of the planting part in the paddy field, and plant seedlings in the paddy field that has been scratched.

[0003]

However, in the case of the former,
The blade provided on the foreign matter pushing body is a dish shape curved in an arc shape and has a structure in which the blade is inclined with respect to an orthogonal line orthogonal to the rotation axis. The curved inner surface and the curved outer surface of the blade are alternately directed toward the front side,
When the curved inner surface is directed to the front side, the clod that has entered the curved inner surface is inverted to cause an embankment, and as a result, the blade cannot scrape appropriately and level it. In addition, there is a problem that the rest of the paddy field that is not affected by the blades is not leveled at all, while in the latter case, the spiral blades rotate the spiral blades to scratch the forward position of the planting part. Although the soil can be leveled, the soil in the scraped portion is fed to one side in the longitudinal direction of the spiral rotor, so that there is a problem in that one side of the spiral rotor in the longitudinal direction can be filled with earth.

According to the present invention, the front of the planting position of the seedlings can be scraped appropriately by the planting claws of the planting section to level the seedlings, and the seedlings can be planted well, and the entire paddy field can be leveled. The purpose of the present invention is to provide a rice transplanter that can be designed.

[0005]

In order to achieve the above object, therefore, in a rice transplanter equipped with a planting section 3 having a planting claw 2 on a traveling machine body 1, the planting section 3 is provided in front of the planting section 3. Rotating body 4 extending in the width direction of the planting part 3 and having a cylindrical surface 40 on the outer surface.
In addition, the elliptical substitute body 5 is disposed on the outer peripheral portion of the cylindrical surface 40 at a position facing the front of the planting claw 2 in the planting section 3, and the major axis side thereof is the rotating body 4. The rotary body 4 is inclined in the longitudinal direction with respect to an orthogonal line that is orthogonal to.

[0006]

When carrying out seedling planting work, however, the rotary member 4 is rotated and the scraping member is disposed at a position corresponding to the front of the planting claw 2 in the planting portion 3 of the rotary member 4. 5, the seedlings are planted by the planting claws 2, and at this time, the substitute scraping body 5 has an elliptical shape, and the rotary body 4 is formed into an orthogonal line orthogonal to the rotary body 4. On the other hand, since it is provided so as to be inclined in the longitudinal direction of the rotating body 4,
At the time of rotation, the scraping part of the scraping body 5 is the planting part 3
In the width direction of the planting portion, that is, left and right alternately, and the soil in the front corresponding position of the planting claw 2 in the planting portion 3 can be moderately scraped and leveled, thereby making it possible to scrape the soil. The seedlings can be satisfactorily planted in the paddy field with the planting claws 2, and the rotating body 4 extends in the width direction of the planting section 3 and has a cylindrical surface 40 on the outer surface. At the same time as the scraping work by the scraping body 5, the cylindrical surface 40 of the rotating body 4
Thus, the remaining portion of the paddy field that is not subjected to the scraping action by the substituting body 5 can also be leveled to achieve leveling of the entire paddy field.
