Abstract

PURPOSE: To increase the effective area of a screen and enlarge the width of a rake by moving the rake fitted at the end of the arm of as creen dust remover in the form of an elongated circle.
CONSTITUTION: Elliptic guide rail 1 and straight guide rail 2 support shafts 6 and 7 via rollers 8 and 9. Shafts 6 and 7 are fitted with arms 10 and 14 in such a manner that they are permitted to move freely. Rake 11 is fitted to the tip of arm 10. Roller 9 is driven along guide rail 2, and roller 8 is moved along guide rail 1 via arm 14 elliptically. Then, rake 11 connected to arm 10 slides on the screen surface and picks up dust and trash. The position of rake 11 to draw an elongated circle is set inbetween screen 12 and guide rail 1. This makes it possible to enlarge the rake width to the full width of the water-way without having the operation of rake 11 constrained by frame 3.
