Agricultural spray, for vegetable variable separation distance crop rows planted in lines, has motor driven spray nozzle support and suspension arms to direct spray in required direction

摘要

Spray pipe suspension arms (8a,8b) are pivoted on a chassis (1) around vertical axes. Supports (9a,9b) are also hinged around vertical axes at the respective ends of the arms (8a,8b). Hydraulic jacks (14) pivot each arm and its associated support so that the spray nozzle (5) is directed in the required direction whatever the position of the suspension arm with respect to the chassis. The agricultural spray comprises: (a) a chassis (1) designed to be carried on a trailer (2); (b) movable suspension arms (8a,8b); (c) supports (9a,9b) at the free ends of the suspension arms; (d) a spray pipe and nozzle (5) carried on the supports, and; (e) hydraulic jack (14) which adjust the position of the suspension arms with respect to the chassis.
