PROBLEM TO BE SOLVED: To provide a seeding machine that can be used by small-scale producers, gardening lovers and vegetable garden lovers with one hand, and thereby allows a small seed to be sown one by one.SOLUTION: A one-grain seeding machine is characterized as follows: an aperture of the lower end of a cylindrical nozzle is made smaller than a diameter of the handled seed to form a nozzle tip; a mechanism for reciprocating the nozzle tip between the bottom of a seed container and the upper end of a discharge pipe with a lever operation is provided; a pneumatic pump is configured such that a discharging force is generated when the nozzle tip is present in the upper end of the discharge pipe and a suction force is generated at the time other than that; and a conduit of the pneumatic pump is connected to the nozzle. The one-grain seeding machine is also configured so as to suck only one seed by the suction force at the time when the nozzle tip is present at the bottom of the seed container, and to discharge the sucked seed with the discharging force and drop it on the hollow of the discharge pipe and discharge it outside from the lower end of the discharge pipe when the nozzle tip moves to the upper end of the discharge pipe. Determination is made whether or not the nozzle tip sucks the seed by whether or not the light pass through from the nozzle tip to the hollow of the nozzle, and an alarm is made when the seed is not sucked, and thereby the state where the one-grain is not sowed is prevented. |
