摘要： PROBLEM TO BE SOLVED: To quickly and positively separate solid materials from charged earth and sand without particularly applying an external force to a sifting means set at a soil charging hopper, and to smoothly and efficiently eliminate the solid materials left on a grating. SOLUTION: A soil charging hopper 30 has a frame body 31 on which a grating unit 32 is installed. The grating unit 32 includes a plurality of grating plates 33 which are arranged in one direction with predetermined pitches so as to cover the upper portion of the soil charging hopper 30. Both ends of each grating plate 33 are rotatably linked to crank portions of respective crank shafts 35, and when one of the crank shafts 35 is driven for rotation, each of the grating plates 33 vertically reciprocates by a predetermined stroke, to thereby cause vibration to the charged earth and sand. When the grating plates 33 reciprocate in a longitudinal direction by a predetermined stroke, solid materials are discharged.
