Summary:The invention discloses an ultrafine-grate screen machine comprising a belt manufactured with a filtering mesh. The belt is tensioned with a driving wheel and a driven wheel. The driving wheel is driven by a driving device. A plurality of scrapers are arranged on the belt. A plurality of filtering holes are arranged on the scrapers. A certain height difference exists between the driving wheel and the driven wheel. A recovery device is arranged below the belt. According to the screen machine with the above structure, the belt is manufactured with the filtering mesh, and is obliquely placed, such that garbage attached to the belt can fall into the recovery device under the effect of gravity when the garbage moves to a position where an attachment end face is facing downwards. Therefore, garbage automatic recovery is realized, and the garbage is prevented from blocking the belt. The work is stable, and no maintenance is needed.
