苗機における高さ制御装置。 a seedling planting device equipped with at least two floats movable up and down; a hydraulic cylinder for raising and lowering the seedling planting device with respect to the field; and a hydraulic cylinder for switching the hydraulic cylinder to raise or lower the seedling planting device. In the rice transplanter equipped with a switching valve, the seedling transplanting device includes a sensor shaft that rotates in conjunction with the vertical movement of two floats, and a sensor whose both ends are connected to the sensor shafts via a shaft coupling mechanism. An output shaft is provided,
The switching valve is connected to the sensor output shaft so that the switching valve is switched to raise or lower the seedling planting device by rotation of the sensor output shaft, and the switching valve is connected to the sensor output shaft so that the switching valve is switched to raise or lower the seedling planting device. A means for biasing the transplantation device to switch to lowering is provided, and a double shaft joint mechanism on the output shaft of the sensor is provided.
1. A height control device for a Tanae machine, characterized in that a play section is provided in which the rotation of each sensor shaft in the float downward movement direction is not transmitted to the sensor output shaft by a certain rotation angle.
