PLANTING MECHANISM OF RICE TRANSPLANTER

PROBLEM TO BE SOLVED: To simply carry out filling, supplying and exchanging lubricating oil of a rotary case in a rotary planting mechanism without soiling hands. SOLUTION: The planting mechanism is constituted by installing a claw case having planting claws on the end of a rotary case 10 to be freely rotatable, integrally connecting an ununiform motion gear transmission mechanism 14 installed in the rotary case 10 to the claw case and synchronously rotating the claw case in ununiform motion in the reverse direction to the rotation direction of the rotary case 10 depending on the rotation in certain direction of the rotary case 10. An injection port 31 of the lubricating oil is installed near the end of the rotary case 10. Preferably, in addition to install a lubricating oil discharge port 36, the injection port 31 and the discharge port 36 are installed to be diagonal to the rotation shaft center of the rotary case 10.
