Description

[Detailed Description of the Invention] The present invention relates to a rice transplanter equipped with a planting section having a seedling stand.

In general, with this type of rice transplanter, when the seedlings on the seedling stand are dry during operation, the resistance between the seedling mat and the seedling stand becomes large, causing a drop in the planting area below the seedling stand. There is a drawback that the feeding of seedlings is not carried out smoothly, and for this reason, the operator sprinkles water on the seedlings as appropriate during the operation to ensure that the seedlings are transferred smoothly to the planting area on the seedling platform. was.

This is not a very troublesome fraud for the driver,
Since the rice planting work is interrupted each time, the efficiency of the rice planting work is extremely low, and this is particularly noticeable as the number of seedlings increases as the rice is planted in multiple rows.

In addition, in a structure in which a convex portion is formed on the upper surface of the seedling table, the seedling mat is supported by the convex portion, and the seedling mat is facilitated in sliding, water is supplied to the convex portion and the seedling mat is in contact with the convex portion. When water is supplied to a portion of the seedling mat, the contact portion of the convex portion of the seedling mat becomes soft and deformed due to the seedling mat's own weight, and there is a concern that the bottom surface of the seedling mat may come into close contact with the top surface of the seedling platform. It was difficult to adjust the water supply to prevent deformation.

Therefore, the present invention is equipped with a seedling stand that is tilted in one direction and supported so that the seedling pine I can be slid down toward the lower end of the slope, and a plurality of convex portions that are brought into contact with the lower surface of the seedling pine I.・・・
