PURPOSE:To simply sow coated seeds without sucking in water by sucking seeds to the tips of suction nozzles, releasing negative pressure in the suction nozzles in seeding and ejecting the seeds with slide pins. CONSTITUTION:Coated seeds 7 are sucked from a seed box to suction nozzles 1 in their state of a negative pressure and pressed against slits of a urethane mat 8 with slide pins 2. When the slide pins are projected to press the seeds against the slits of the urethane mat, the negative pressure in the suction nozzles is released with negative pressure releasing mechanisms 4 to prevent water from being sucked from the urethane mat or a nursery box 9 into the suction nozzles. |
