The utility model discloses an engineering machinery is with falling silencer of making an uproar, including intake pipe, blast pipe and outer barrel, the internal portion of urceolus splits into the chamber of admitting air, first expansion chamber, four cavitys in the second expansion chamber and exhaust chamber by baffle I, baffle II and baffle III in proper order, it has arranged the intake pipe to admit air the chamber, honeycomb duct I is arranged to baffle I and baffle between II, honeycomb duct II is arranged to baffle II and baffle between III, arrange the insert tube on the baffle III, intercommunication second expansion chamber and exhaust chamber, the blast pipe has been arranged in the exhaust chamber. The utility model discloses the fluid passes through between the baffle honeycomb duct and the insert tube is propagated in each cavity, through setting up different expansion chamber length and divergence ratio, obtains ideal noise elimination frequency, effectively reduces the exhaust noise, reduces power consumption, and is energy -concerving and environment -protective, improves the operation travelling comfort, the life of extension silencer.
