Through a parallel link mechanism consisting of a rear vertical link that is pivotally connected,
For planting, a device is connected to the machine so as to be movable up and down, and a cylinder for driving the parallel link mechanism is installed between the upper link or its interlocking member and the fixed part on the machine side. The planting is carried out between the upper link, the lower link, the vertical link, and the rear vertical link or their interlocking members in the lower range of the entire vertical range of the device. Parallel swinging motion of the parallel rotation link mechanism is allowed, and in an upper range, any two of the links or their interlocking members are abutted and locked to each other, so that the parallel rotation movement of the parallel rotation link mechanism is allowed. Planting in a rice transplanter that is equipped with a member that prevents rocking movements is related to a device lifting mechanism.

In the above rice transplanter, the device's lifting mechanism is a single driving cylinder, and among the entire lifting range of the device, the lower range for planting depth adjustment is used for planting. Regardless of the lifting and lowering of the device, the posture of the device relative to the machine should be maintained constant or almost constant during planting, and the planting should be done without disturbances in posture or poor seedling feeding performance on the slanted seedling stand. For planting, the device can be raised and lowered in parallel while ensuring operation, and in the upper range, the slanted seedling stand of the device is placed in a nearly horizontal position, and the seedlings are placed on this seedling stand. In order to make replenishment convenient, the planting device can be rotated up and down so that the position of the seedling stand gradually approaches the horizontal position. If the motion conversion position is set at a fixed position, efficient planting may not be possible.

In other words, if the range of parallel vertical movement is set wide,
Although it is possible to work efficiently even in deep wet fields, in shallow wet fields, it is not possible to quickly rotate the device up and down when turning around near the edge of the bank. In this case, even when turning, the planting device can be rotated up and down quickly, allowing for efficient work, but in deep wet fields, the planting device itself cannot be raised and lowered parallel to the planting surface.

In other words, by changing and setting the deformation state of the link mechanism when parallel rocking motion is prevented, for example, if parallel rocking motion is prevented with a shape close to a rectangle, planting will be done within the parallel lifting motion range of the device. If the shape becomes narrower and the parallel swing motion is prevented by a shape close to a rhombus, the range of the parallel lifting motion becomes wider, and the motion conversion position can be easily changed and adjusted according to the depth of the wet field.
