Conventionally, small flowerpot-shaped pot trays formed of vinyl chloride or the like are placed in a pot case and arranged vertically and horizontally, and a plurality of pot trays are placed in the pot case to collapse the pot tray. Although prevention and simplification of soiling and transplanting work were attempted, the work efficiency was increased because the tray filling work to put the pot tray in the pot case and the soil feeding work to put the soil in the tray were performed manually. There is a problem that it is not possible to easily improve the quality and the like. In addition, when putting nutrients into the tray, it takes time and skill to work evenly and always in an appropriate amount without over-tightening the soil.

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a pot tray soil feeding apparatus for feeding soil from a soil feeding section to a pot tray on a conveyor, from the lower side of the pot tray after feeding the soil. Providing a vibrating part that intermittently vibrates the pot tray, so that the nutrient filled in the pot tray is not over-tightened, making it possible to achieve good leveling even with soil that is difficult to level. Things.

Further, in a soil feeding apparatus for a pot tray for feeding soil from a soil feeding section to a pot tray on a conveyor, a soil stirring section for stirring the soil near an outlet of the soil feeding section. Is provided to prevent the soil from becoming a bridge at the exit of the soil feeding section during the soil feeding operation, thereby enabling smooth and good soil feeding at all times.

[0005] Further, a feed rate control unit for keeping the feed rate of the soil nourishment is provided near the outlet of the soil feed unit, so that even if the humidity and the homogeneity of the soil are different from each other, the feed rate of the nutrient is substantially constant. The soil can be supplied to improve the filling accuracy of the soil.
