Abstract

An automatic system for operating the distributor box 9 of the hydraulic motor of device 1 for delivering fertiliser to irrigation conduits comprising a metering pump A having a piston 5 and a hydraulic motor B, C having a piston 8 comprising an operating device 29 capable of accumulating potential energy provided by a first shaft 13 axially loaded by the piston of the hydraulic motor to then provide it to a second shaft 14 for the operation of buffers 11, 12 in distributor box 9. Operating device 29 comprises a pair of systems 35, 36 having elastic instability and associated with said shafts 13 and 14 respectively comprising a pair of forks 20, 25 which at the ends of their prongs bear corresponding elastic blades 21, 26, enclosed between two corresponding pairs of transverse members 32, 33, which are loaded on the tip by two corresponding pairs of plates 30, 31 which can move and are spring-loaded axially by corresponding pairs of helicoidal springs 22, 27 with a loading which can be adjusted by means of corresponding pairs of screws 23, 28. <IMAGE>
