HYDRAULICALLY DRIVEN DUST CLEANER FOR NARROW AGRICULTURAL DRAINAGE CANAL

摘要

PROBLEM TO BE SOLVED: To provide a hydraulically driven dust cleaner capable of raking up dust with hydraulic power in a comparatively narrow agricultural drainage canal.;SOLUTION: The hydraulically driven dust cleaner comprises a water wheel 1 composed of a hollow watertight drum 11 and a plurality of blades 12 provided at circumferentially equal spaces on the outer periphery of the watertight drum 11, and rotated around an axis X of the watertight drum 11. The water wheel 11 is arranged so that its axis X is orthogonal to the canal 6, and moves within a depth region A of the canal 6 with its lowest position set to the height at which the blades 12 are not in contact with the water surface S. The water wheel 1 may be supported to the free end 14b of a swing arm 14 with its base end 14a journaled to a member 13 fixed to an installation face.;COPYRIGHT: (C)2007,JPO&INPIT
