The invention discloses a materials and sundries clearing device and a method thereof, which belongs to the technical field of mineral screening. The device includes a screen which consists of a grating, a sleeve, a base and frames. The screen is located in the hopper and the upper part of the screen is located under a scraper blade of an upper belt head wheel. A transmission shaft is arranged in the bottom of the screen and connected to a transmission connecting rod. An inclined chute is arranged under the base of the screen and is located outside the hopper. The method includes the steps that the transmission connecting rod is driven through a motor, the transmission connecting rod drives a transmission shaft to adjust the angle between the plane where the screen is located and the horizontal direction to be over 70 DEG C and less than 90 DEG C. The materials drop on the belt through the screen and the sundries are left on the screen.
