The invention relates to an apparatus for preventing clogging of screen holes of a soil sorting machine. The soil sorting machine is provided with drum screens with the screen holes and a driving source suitable for rotating the drum screens. Soil is precisely classified through the screen holes. The apparatus comprises at least one or multiple impacting induced protruding parts which protrude from outer peripheral surfaces of ends not provided with the screen holes of the drum screens or the outer peripheral surface at two ends of each drum screen, impacting rollers and scrapers. The impacting rollers are suitable for elastic movement so that the impacting rollers are capable of climbing over the impacting induced protruding parts while being in rolling contact with the outer peripheral surface at two ends of each drum screen. The scrapers are suitable for carrying out operation in cooperation with each impacting roller so that the screen holes of the drum screen are impacted and soil is scrapped via the scr
