[Effect] In a configuration in which a feeding mechanism is provided for each planting mechanism, the transfer path between the feeding mechanism and the groove generator is similar to the rice transplanter proposed in Japanese Patent Application No. 9-22447 filed earlier. In order to make the length condition equal in each section, the feeding mechanism is arranged so that the horizontal position of the feeding port and each planting mechanism substantially coincide with each other. As a result, the left and right sides of the hopper mounted above the feeding mechanism are arranged. The width was almost as wide as the left and right width of the seedling table. Therefore, even if the planting section is folded as it is, the right and left widths of the hopper cannot be reduced, and the effect of reducing the entire width of the machine cannot be expected.

Therefore, according to the first aspect of the present invention, the supply unit is disposed in the center area in the left-right direction of the traveling body, and the plurality of transfer paths are arranged on the planting mechanism side more than the supply unit side in plan view. Because it was arranged so that it is almost radial with a wide left and right width,
By setting the left and right lengths of the hopper smaller than before, it is possible to set the length of each transfer path as small as possible while enabling technology to reduce the body width such as the folding structure of the planting part become. For example, it is possible to minimize the difference between the maximum length and the minimum length of the transfer path as compared to the case where the supply unit is arranged at a position shifted left and right from the center area on the left and right.

According to the second aspect of the present invention, the hopper in the supply section can be replaced, and the hopper can be replaced with one having a longer front-to-rear length so as to cope with an increase in the number of vines. Even if the number is different, the entire width of the supply section can be kept unchanged. Further, it is also possible to absorb the increase / decrease of the storage amount of the granular material according to the size of the field by changing the front / rear length of the hopper so that the width is not widened.

According to the fifth aspect of the present invention, since the lengths of the plurality of transfer paths, which are substantially radial in plan view, are all equal to each other, after the feeding mechanism is driven, the granular material actually forms the groove generator. Thus, the time required for supply to the field via the same does not change, and the supply start uniformity of the granular material can be further improved. For example, in a rice transplanter equipped with a fertilizer application, the start position of supply of fertilizer accompanying seedling planting can be made equal in all planting lines. In order to make the lengths of the transfer paths equal, it is conceivable to increase the slack amount of the hose toward the center in the left or right direction or increase the number or amount of bending to the left or right.

According to the sixth aspect of the present invention, the transfer force of the granular material can be enhanced by the blowing means, and the wind force in the transfer path becomes stronger as the distance from the center in the left and right direction to the left and right sides increases. Therefore, as in the case where each transfer path is set to the minimum necessary length, the time required for the granular material to move along the central transfer path where the path can be shortened the longest and the longest path It is possible to make the time required for the granular material to move through the transfer paths at the left and right ends the same, that is, to make the movement time of the granular material equal in any transfer path. That is, as described above, in the rice transplanter with the fertilizer application, the supply start position of the fertilizer accompanying the seedling planting can be made equal in all the planting streaks.
