A steel wheel roller wheel sticking material scraping device comprises a scraping plate and a support for connecting the scraping plate onto a roller frame. The support includes a transverse steel plate, two inserting plates and two springs; the two inserting plates and the two springs are symmetrically connected between the transverse steel plate and the roller frame; a pin frame is fixedly connected onto the roller frame; one end of each inserting plate is connected with the pin frame; the other end of each inserting plate is fixedly connected with the transverse steel plate; the U-shaped scraping plate is clamped onto the transverse steel plate; and a row of inserting pins penetrating through the scraping plate and the steel plate is used for connecting the scraping plate together with the steel plate. The device can automatically scrape away mixed materials stuck onto a rolling wheel of a roller without manual unsticking any more, thereby being extremely safe and reliable, and being capable of saving a large amount of labor and time. In addition, the device has the advantages of simple structure, low manufacturing cost and convenient maintenance and use, and can be popularized and used widely.
