装置５の左右傾斜を抑制できるに至つた。 In other words, depending on the hardness or softness of the soil in the field, the restoration biasing force is greater when the soil is soft than when it is hard, so regardless of whether the soil changes in hardness or softness,
It is possible to absorb changes in the support force for the float 8 by applying suitable restoring force to each, and to suppress the left and right inclination caused by the lateral movement of the seedling stand 10. In addition, the initial setting is large enough to cope with soft conditions. It is possible to avoid unnecessary resistance to the lateral movement of the seedling stand 10 when the seedling stand 10 is hard, as in the case of applying a biasing force,
Overall, it is possible to suppress the horizontal tilting of the seedling planting device 5 due to the lateral movement of the seedling platform 10, regardless of the soil quality of the field, while allowing the lateral movement of the seedling platform 10 to be carried out smoothly with little resistance. I've reached it.
