Claims

[Scope of utility model registration request]

A seedling planting device B is connected to the rear end of an elevating link mechanism 4 installed at the rear of the traveling vehicle body A in a rolling manner, and
A spring 13.1 extends between the lifting link mechanism 4 and a portion that is deviated to the left and right with respect to the rolling fulcrum P of the seedling planting device B.
The rice transplanter is configured to restore and bias the seedling planting device B to a rolling neutral posture by tensioning each of the springs 13 and 13, respectively, and a spring holder that connects and supports both springs 13 and 13 to the seedling planting device B. The arm 11 is horizontally mounted, and both springs 13.1
3 are configured to the same specifications, and the distances x and x' between the rolling fulcrum P and the spring receivers to the spring connection points 11a and lla at both ends of the arm 11 are different in advance according to the left-right weight balance of the seedling planting device B. When the seedling planting device B is at a predetermined lifting position that is out of the planting work level, the spring receiver is attached to the arm 11, and the left and right lower links 4B of the lifting link mechanism 4 A rice transplanter in which a rolling lock abutting member 11c that abuts against the 4B to fix the seedling planting device B in a horizontal position is fixed in such a manner that the spring receiver projects forward at an angle of 11°.
