Trough group transport device and method for transporting troughs in pitch-increase type hydroponic cultivation facility

摘要

PROBLEM TO BE SOLVED: To administer multiple troughs fix planted with green vegetables by varying their pitches according to the growth and changing alignment to have a little larger pitch in daily conveying. SOLUTION: This system has a troughs carrier 4 shuttle which moves in a constant stroke, to convey the troughs groups 2 integrated with troughs having same pitch, equipped with a trough stopper holder 5 moving back-and-forth parallel to the carrier 4 at the side. The holder 5 has stoppers 6 positioned on the troughs pitch p1 gradually increasing according to the growth of the green vegetables, each troughs 1 contacts with stopper 6 while reciprocating the trough carrier 4, capable of moving each troughs 1 to place in the pitch according to the growth of the green vegetables while sliding the troughs to a supporting beam 9 inhibiting excess movement to the prescribed range.
