System and method for cultivating plant products

A shelf for cultivating plant products having a reference axis and comprising:

• a supporting frame,
• a plurality of cultivation bars which have an approximately rectilinear shape, extend along respective longitudinal axes, and are coupled to said supporting frame so as to be arranged approximately coplanar and alongside one another in order to have the respective longitudinal axes parallel to said reference axis,
• mechanical spacing members, which are interleaved between the cultivation bars and are structured so that the actuation of a mechanical spacing member causes at least a pre-established variation of the distance transverse to said reference axis, between two adjacent cultivation bars adjacent to the actuated mechanical spacing member;
• said mechanical spacing members are structured so as to be operated between a first operating condition, in which the mechanical spacing member positions the two adjacent cultivation bars at a first pre-established distance one with respect to the other while keeping them mutually parallel, and a second operating condition, in which the mechanical spacing member arranges the two adjacent cultivation bars at a second pre-established distance greater than the first pre-established distance, keeping them parallel to one another,
• said shelf being characterised in that said mechanical spacing members comprise respective rectangular bellows-structured sheets, foldable along a folding line which extends parallel to the longitudinal axis of the bars and is approximately defined by the intersection of the respective rectangular sheet and the centre-line plane thereof.

An operating method for a system for cultivating plant products without soil comprising a plurality of shelves for cultivating said plant products, wherein each said shelf has a reference axis;

• said method comprising:
• prearranging a supporting frame,
• prearranging a plurality of cultivation bars which have an approximately rectilinear shape and extend along respective longitudinal axes,
• interleaving, between said cultivation bars, mechanical spacing members, which are structured so that the actuation of a mechanical spacing member causes a variation of the distance, transverse to said reference axis, between two adjacent cultivation bars adjacent to the same;
• said mechanical spacing members are structured so as to be operated between a first operating condition, in which the mechanical spacing member positions the two adjacent cultivation bars at a first pre-established distance one with respect to the other while keeping them mutually parallel, and a second operating condition, in which the mechanical spacing member arranges the two adjacent cultivation bars at a second pre-established distance greater than the first pre-established distance, keeping them parallel to one another, said mechanical spacing members comprise respective rectangular bellows-structured sheets, foldable along a folding line which extends parallel to the longitudinal axis of the bars and is approximately defined by the intersection of the respective rectangular sheet and the centre-line plane thereof,
• coupling said bars to said supporting frame so as to arrange them approximately coplanar and alongside one another so as to have the longitudinal axes parallel to said reference axis;
• said method being characterised in that it comprises the step of opening at least one or more of said foldable sheets to move the respective two adjacent cultivation bars connected to the same by moving them away and spacing them apart from one another until reaching, at the end of the opening movement, said second pre-established distance in which said bars are still parallel to one another.
