ECOLOGICAL WIDE ACROP DUSTER HAVING MULTI-STAGED AXIAL FLOW FANS农业专利-农业学术服务平台

摘要：: The present invention relates to a multi-staged axial flow blowing system for the ecofriendly microorganism wide spreader. More specifically, the multi-staged axial flow blowing system includes a blower fan, which generates enough airflow while having fewer blades. The multi-staged axial flow blowing system can generate increased wind pressure and is capable of controlling pests in a wide area. The multi-staged axial flow blowing system includes: a blowing duct; an engine; a housing; a driving bevel gear rotated in the housing; a gear part including a first driven bevel gear and a second driven bevel gear; a first blowing fan having a hub around which the blades are radially and symmetrically arranged; a second blowing fan having a hub around which the blades are radially and symmetrically arranged; and a spraying nozzle for spraying a microbial agent.
