<p>Provided is a rice planting machine that optimizes the trajectory of planting claws and prevents planting errors, by applying torque that negates torque fluctuation occurring in a planting arm shaft, levelling torque fluctuation, and improving phase shift. The planting machine transmits dynamic force via a non-uniform speed mechanism to a planting arm shaft that supports the rotary case and has provided therein a torque-negating mechanism that applies torque that negates torque fluctuation caused by the non-uniform speed mechanism. The torque-negating mechanism has: a crank section wherein part of a planting vertical shaft that transmits dynamic force to the planting arm shaft is formed in a crank shape; and a spring attached to the crank section. Torque is applied by the spring.</p> |
