"Problems to be solved by the invention" In Japanese Utility Model Application Laid-Open No. Sho 62-104628, the height of the fertilizer nozzle is kept constant during the work, while the height of the fertilizer nozzle is freely changed in multiple stages. Therefore, there is a problem that the fertilizer nozzle is deformed when the fertilizer nozzle comes into contact with stones in the soil. Further, in Japanese Utility Model Application Laid-Open No. 2-111222, the fertilizing nozzle is pressed downward by a spring so as to be able to move freely, so that the fertilizing nozzle can be prevented from being damaged. Since the upper end of the nozzle is fixed, it is assumed that the structure is such that the discharge port of the fertilizing nozzle is movably mounted on the connecting pipe as a fulcrum, so a bearing structure for rotatably mounting the connecting pipe on the planting float is required. In addition, it is necessary to specially provide a receiving member on which the spring is provided, and thus there is a problem that simplification of the fertilizing nozzle mounting structure and reduction of the manufacturing cost cannot be easily achieved.
