Claims

[Scope of utility model registration request]

The rice transplanting device 11 is attached to the rear of the traveling vehicle 10, and the rice transplanting float 12 side and the control lever 28 of the control valve 26 for raising and lowering the wheels 6 are interlocked and connected by a pressing force adjustment mechanism 32. The control valve 26 is operated to detect the vertical movement of the rice planting float 12 and adjust the pressing force of the rice planting float 12, and this operation causes the wheels 6 to move up and down with respect to the body 29, and the control lever 28 to return to its initial position. In the device comprising a valve return spring 43 and a rice transplanting side return spring 41 that presses and biases the rice transplanting float 12 downward against the valve return spring 43, the sowing device 3 is detachably attached to the rear of the rice transplanting device 11. The seeding float 22 side and the control lever 28 are removably connected to each other by a pressing force adjustment mechanism 57 in order to detect the vertical movement of the seeding float 22 and adjust the pressing force. A sowing-side return spring 53 is provided which presses and urges the sowing float 22 downward, and the spring force of the sowing-side return spring 53 is greater than the spring force of the valve return spring 43, and the spring force of the rice-planting side return spring 41 is greater than the spring force of the valve return spring 43. is smaller than the spring force of the valve return spring 43, and can be freely adjusted to be larger than the spring force of the valve return spring 43 by a spring force adjustment mechanism.
