Title:
HYDROPONICS APPARATUS ATTACHED WITH PLANT-SOAKING DEVICE FOR PEST CONTROL
Document Type and Number:
Japanese Patent JP3968757
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a simplified device for soaking a plant setting panel in culture solution.
SOLUTION: This hydroponics apparatus attached with a plant soaking device for pest control has a sinking and floating driving device. The sinking and floating driving device performs sinking and floating a pair of air boxes and the plant-setting panel through making on at least the inner bottom of both wall sides facing each other in a box type tank containing culture solution, a pair of pits for lifting and lowering guide hanging down deeper than the inner bottom, inserting a pair of the air boxes liftably and lowerably into a pair of the pits respectively, supporting the plant-setting panel on both the air boxes to put in a relation where the plant-setting panel floats on a culture solution surface when the air box lifts in the pit, and the plant-setting panel sinks in culture solution surface when the air box lowers, and selectively supplying air and the culture solution in the tank into a pair of the air boxes.
