PROBLEM TO BE SOLVED: To provide a movable dust collector which alleviates labor for removing algae growing in a river, loading the same, and conveying the same. SOLUTION: The movable dust collector is constructed by attaching a two-way rake 64 which can perform vertical movement and rotational movement, to the tip of a crane of a truck with crane, and raking the algae under the water surface of the river, and loading the raked algae on the truck. By connecting the two-way rake 64 to a hydraulic motor 68 incorporated in a case (3) 40, for rotation, the rake carries out vertical operation. Further by allowing reciprocal rotation of the case (3) 40, the dust collector carries out consistent procedures of raking the algae, loading the same, and conveying the same. COPYRIGHT: (C)2004,JPO
