Abstract
Una apparecchiatura perfezionata per la riduzione del rumore alla fonte, in particolare per impianti per la produzione di manufatti in c.s. vibrato, comprende due strutture speculari (10, 11) destinate ad essere fissate rispettivamente ad un generatore di vibrazioni (12) e ad un cassero. Dette strutture (10, 11) sono intercollegate mediante oscillatori costituiti dalla combinazione di: perni (13) passanti, con l'interposizione di un manicotto (16), attraverso rispettivi fori previsti almeno nella struttura vibrante (10). Fra le strutture (10, 11) e fra almeno la struttura vibrante (10) ed un dado terminale (14) avvitato su una estremità di detti perni (13) sporgente dalla struttura vibrante (10), sono previsti elementi elastici (15).An improved equipment for the reduction of noise at the source, in particular for systems for the production of concrete products vibrato, comprises two mirror structures (10, 11) intended to be fixed respectively to a vibration generator (12) and to a formwork. Said structures (10, 11) are interconnected by means of oscillators consisting of the combination of: through pins (13), with the interposition of a sleeve (16), through respective holes provided at least in the vibrating structure (10). Elastic elements (15) are provided between the structures (10, 11) and between at least the vibrating structure (10) and an end nut (14) screwed on one end of said pins (13) protruding from the vibrating structure (10).
