The input shaft 35 on the blower unit side that has obtained rotational power from the O-axis
The rotation is transmitted to the blower fan 37 through the large-diameter pulley 44 and the small-diameter pulley 42, and the wind generated by the blower fan 37 is guided into the conduit 48. The fertilizer riding on the wind is passed through the branch pipe 50 and the fertilizer discharge pipe 56, and is sprayed into the field from the tip discharge port 57 of the fertilizer discharge pipe 56. Depending on the shape and location of the field, the spraying may be switched from uniform spraying over the entire surface to spraying on only one side. In such a case, the discharge direction may be selected by appropriately switching the shutter adjustment lever 64.
If the fertilizer does not fly in the desired direction due to strong winds during the work, the discharge direction and angle of the fertilizer discharge pipes 56, 56 are appropriately adjusted. In such a case, a single operation lever is required. The direction of the fertilizer discharge pipes 56, 56 is changed by rotating the 86 vertically or horizontally. For example, when the fertilizer discharge tube 56 is to be directed upward, the operation lever is required.
In FIG. 11, the pivot 86 is rotated in the direction of the arrow A about the axis of the fulcrum bolt 89, and when turned downward, it is rotated in the direction of the arrow B. And the fertilizer discharge pipes 56, 56
