摘要
The present invention is characterized in that the connecting bars connecting and fixing the screen bars of the main screen at a predetermined interval are formed in a concave shape with a constant curvature in a circular arc shape gradually toward the both side ends so that the screen bar is connected to the connecting bar The front side of the neck portion is narrowly spaced at a predetermined distance so as to be connected and fixed so that the contaminants of the water flowing in the water channel are caught in front of the neck between the screen bars and at this time the contaminants between the screen bars are filtered So that the neck of the screen bars can be prevented from being caused by the rake so as to smoothly flow the water without any resistance by the obstacle, A neck portion of the screen bar fixed to the neck is narrowed, The present invention relates to a rotary damper for preventing a hammer from being hampered by smooth contact of the damper with the damper so that the damper can smoothly and easily hang the damper and the maintenance and repairing cost of the rotary damper can be reduced.A connecting bar 210 connecting and fixing the screen bars 131 of the main screen 130 at a predetermined interval is formed in such a manner that a curvature R of a circular arc gradually increases toward both ends of the connecting bar 210, So that the screen bars 131 are connected to the connecting bar 21 by a predetermined distance in a narrow width of the front part of the neck, The rake 150 for filtering the contaminants caught on the disposable screen 140 and the rake 150 is also concave so that the width of the screen bar 131 fixed to the connecting bar 210 is narrow, The apron 160 for guiding the rake 150 to the rear is formed so as to be concave at the central portion to be in contact with the rake 150 and to be directed toward the both ends And the curvature R is gradually increased in a circular arc shape.;
