Claims

[Scope of utility model registration request]

A pair of left and right wheels are mounted on the left and right sides of the machine body on which the seedling planting mechanism is installed, respectively, so as to be able to move up and down independently through swing arms that extend backward, and a lifting mechanism is connected to the left and right swing arms. The machine is formed into a U-shape in plan view, consisting of a front and rear longitudinal swing rod connected to both swing arms and a swing plate rotatably attached to one end of the swing rod. A main hydraulic cylinder that is driven in accordance with the detection is provided in the front and back direction along the center line of the aircraft body, and the main hydraulic cylinder' is horizontally rotatably connected to the center of the swing plate to drive the main hydraulic cylinder. The left and right wheels are configured to move up and down at the same time, and between the midway part of the swing plate and one of the swing rods, one swing arm is connected to the other swing arm. A traveling device for a rice transplanter that includes a rolling hydraulic cylinder that moves up and down in the opposite direction.
