PURPOSE: A dedust unit is provided to easily salvage an adulteration from a screen by separating the adulteration interrupted by the screen when a rake falls. CONSTITUTION: A dedust unit comprises a rake(110), an inner arm(125), an outer arm(120) and a main body(130). The rake salvages an adulteration by reciprocating up and down along one surface of a screen installed in a waterway. The rake separates the adulteration interrupted by the screen when falling. The inner arm is coupled so that the rake can rotate. The outer arm is coupled so that the inner arm can reciprocate. The main body is coupled so that the outer arm can reciprocate. |
