The utility model relates to the technical field of corn seed production, and provides a seed
germination humidifying device for corn seed production, which comprises a box body and a humidifying mechanism. The liquid level instrument, the
circulating pump and the connecting
pipe are arranged, the liquid level instrument detects the amount of mixed liquid in the
germination box, then the controller controls the
circulating pump to pump out residual
nutrient solution, the residual
nutrient solution passes through the connecting
pipe and the three-way
electromagnetic valve and then is sprayed out of the spray head, seeds are humidified in a circulating mode, and the
nutrient solution is fully utilized; a three-way
electromagnetic valve controls a
water flow source, then the
water flow is sprayed out from a spray head to humidify seeds, a filter plate and a
handle are arranged, the seeds are placed on the filter plate to be humidified, a
nutrient solution falls to the lower portion through the filter plate to be circulated, after
germination, the filter plate is taken out by pulling the
handle, and the germinated seeds can be conveniently taken out; by arranging the water tank, the
nutrient solution tank, the water pump and the
nutrient solution pump, a nutrient solution is stored in the nutrient solution tank, and water and the nutrient solution are pumped out by the water pump and the nutrient solution pump, so that seeds germinate better.
