A front screen of a dust catcher is provided to remove the entire quantity of dust and rubbish with a dust and rubbish removal rake without the accumulation of rust and rubbish on the lower part of a screen device. A front screen of a dust catcher comprises a plate-type base supported to the bottom of an open channel formed in the same width as the breath of a screen device(1), and many front diaphragms(3) arranged continuously on the top of the plate-type base at regular intervals. The front diaphragm comprises an upward entry inclined portion formed to be inclined upward toward the rear to the inside of a turning radius of a dust and rubbish removal rake(13), a stop portion(5) formed to stop dust and rubbish within a turning radius of the dust and rubbish removal rake, and an upward movement guide portion(6) extended upward from the stop portion. |
