Rice transplanter

田植機

Abstract

PROBLEM TO BE SOLVED: To provide a rice transplanter so constructed as to divide a seedling planting apparatus into left and right portions and be switchable between a normal operation posture with the portions arranged left and right and joined to each other and a housing posture with the portions folded in narrow width, ensuring the folding or restoring operation for the seedling planting apparatus to be made smoothly. SOLUTION: This rice transplanter has the following construction: Rolling returning springs 35L and 35R are set up over a fixing site located at the lateral center of the seedling planting apparatus 3 and the left and right divided planting apparatus portions 3L and 3R, wherein one end of a supporting rod 36 is joined to one end of the one rolling returning spring 35L, and the other end of the spring 35L and the other end of the supporting rod 36 are joined to the fixing site and the one portion 3L, respectively, and the joining position for the other end of the spring 35L or the other end of the supporting rod 36 is made switchable between normal tensioning position and slackening position.
