Agricultural spraying boom

Abstract

Abstract 1. Agricultural spray boom carried by the chassis (1) of a spraying implement and comprising at least two lateral boom elements (3, 4) which are telescopically connected, at least one of the lateral elements (14) being movable ; motor means (7-10, 76-78) for producing telescopic movement between these two elements : spray nozzles (5', 5") carried by each of the two lateral boom elements (3, 4) ; means (32, 33, 34) for feeding spraying fluid suitable for each series of nozzles (5', 5") carried by the said lateral boom elements (3, 4), the means (34) for feeding at least the series of nozzles (5") carried by the movable boom element (4) being in part movable or deformable in order to conform to the relative longitudinal position of the said lateral boom elements (3, 4) and the said means (34) of supplying the series of nozzles (5") of the movable boom element (4) comprising two members (12, 13) carried respectively by the said lateral elements (3, 4), characterised in that the said means of ferding at least the series of nozzles (5") of the movable ramp element (4) comprise a collector (34) of the telescopic type comprising two male and female tubular members (12, 13) sliding one in the other in fluid-tight fashion, each being fixed on one of the said lateral boom elements (3, 4), one of the tubular members communicating with a source of spraying fluid, the other tubular member communicating with the said nozzles.
