| 摘要 |
<p>The invention concerns a method and a device for displacing and positioning growing troughs (2) in an horticultural installation, comprising a cultivation field (1) whereon the troughs are displaced, as the plants grow, in a direction roughly perpendicular to the longitudinal direction of the troughs, from one end of the cultivation field to the other, using a forward moving bridge (3) extending across the cultivation field parallel to the longitudinal direction of the growth troughs and mobile along the cultivation field, bearing conveyor fingers (5) capable of being engaged in the growth troughs and displace them along the cultivation field. A transmitter (15), set on the forward moving bridge, is located at a specific distance (a) from the most downstream growth trough and is activated to signal the presence of a preceding trough, thereby enabling to position a trough or group of troughs at a specific distance (c) from one growth trough preceding them in the forward moving direction.</p> |
