EXHAUST AIR DUCT WASHING DEVICE FOR ROAD SWEEPING VEHICLE FOR IMPROVE SUCTION POWER

摘要

PURPOSE: An exhaust duct washing device for a road sweeping vehicle for improving suction force is provided to improve suction force by washing an exhaust duct with water using multiple washing units. CONSTITUTION: An exhaust duct washing device for a road sweeping vehicle for improving suction force comprises a pair of fixed washing units(100), a rotary washing unit(200), and an inclined exhaust passage. Each fixed washing unit comprises a washing unit housing, a fixed adapter, a washing water nipple, and a washing water nozzle. The washing unit housing is installed on the front plate(3a) of an exhaust duct(3). The fixed adapter is coupled to the washing unit housing. The washing water nipple and nozzle are coupled to both ends of the fixed adapter. The rotary washing unit comprises a washing unit housing, a bearing bushing, a rotary adapter, a housing cover, a washing water nipple, a washing water nozzle, and a swing cylinder. The washing unit housing is installed on the front plate of the exhaust duct. The bearing bushing is installed on a latching flange of the washing unit housing. The housing cover is inserted onto the outer surface of the rotary adapter. The swing lever is integrally attached to the outer surface of the rotary adapter and is connected to a cylinder bracket attached to the front plate of the exhaust duct. The inclined exhaust passage is inclined downward.
