Abstract
A planetary gear train type rice seedling transplanter is disclosed. A left and a right gear boxes are driven by a central sprocket in a sprocket case for making them rotate. Two cylindrical planetary gears engaged with the static central cylindrical gear in the said gear box rotate with the gear box to drive the coaxial elliptical gear to rotate, and the said elliptical gear is further engaged with the elliptical planetary gear, so resulting in that the said elliptical gear rotates at non-uniform speed relatively to the gear box. The absolute movement of a transplanting arm pair is the composition of the circumference movement of gear box and the non-uniform movement of elliptical planetary gear. Its advantages are low inertial force, no damage to rice seedlings and reasonable structure.
