However, in the above-mentioned conventional structure, the grounding float is also used as the means for detecting the posture of the seedling plant with respect to the mud surface, and is vertically moved relative to the planting transmission case. Therefore, if the sinking amount of the grounding float changes due to the difference in hardness and softness of the mud, etc., the height of the wheel mark erasing leveling tool with respect to the mud surface will be different.
As a result, for example, when the sinking amount of the grounding float is small, there is a possibility that the height adjustment by the grounding float cannot be performed by the ground adjuster flushing the mud in front of the float laterally outward with the movement of the aircraft, When the sinking amount is large, there is a drawback that the wheel mark erasing action by the grading implement is insufficient and the height cannot be accurately detected by the grounding float. Also, the upper part of the front side of the grounding float is open, and the mud splashed by the wheels may fall on the grounding float through the upper part of the leveling implement, and may accumulate. There was also a problem that the detection accuracy of the sacrifice decreased. An object of the present invention is to eliminate the above-mentioned disadvantages.

The feature of the present invention is that in the rice transplanter described at the outset, the above-mentioned ground adjuster is supported so as to be movable up and down relative to the frame of the seedling planting apparatus. The operation lever for vertical height adjustment is extended upward, and the lever guide plate for locking and guiding the height adjustment locking portion formed on the operation lever is set in a forwardly lowered position above the front end of the ground float. It is arranged so as to constitute mudguard means for muddy water scattered from the front wheel side.

When the mud in the field is hard and the sink of the grounding float is small, for example, by adjusting the leveling tool relatively high with respect to the frame, excessive mud pushing by the leveling tool is reduced. Conversely, when the mud is soft, it can be adjusted low to suppress the adverse effects of wheel marks. In addition, since the lever guide plate that locks and guides the operation lever for adjusting the height of the ground adjuster is located above the front end of the ground float, the mud flipped up by the wheels is received by the lever guide plate, It is possible to suppress falling on the ground float.

[Advantage of the Invention] Therefore, the accuracy of detecting the posture of the seedling plant with respect to the mud surface by means of the grounding float can be improved by adjusting the height of the leveling implement according to the situation of the field. The lever guide plate required to make the ground leveling equipment adjustable so as to suppress the splashing mud scattered from the wheels from falling on the ground float,
It is also possible to prevent the detection accuracy of the mud surface attitude from being lowered due to the accumulation of soil.
