The conventional grit removing machine a front screen has a problem in that as rake bars of a rake having a function of collecting adulteration pass front screen bars of the front screen, the rake bars should be formed to alternate with the front screen bars, and thus the rake bars have a gap as much as the width of the front screen bars, so that fine adulteration escapes from the gap, and it is hard to collect the adulteration. To solve the problem, there is no gap between the rake bars constituting the rake, thereby preventing the adulteration collected by the rake from being swept away by water flow, and easily collecting the fine adulteration contained in the water. |
