The invention discloses a novel soil remediation and screening device. The soil remediation and screening device comprises a box body, and the box body is of an up-down penetrating structure. A first screening plate is arranged on one side wall in the upper portion of the box body in a downwards-inclining mode through first articulation pieces, a second screening plate is arranged on the other side wall in the lower portion of the box body in a downwards-inclining mode through second articulation pieces, and one side wall in the box body is parallelly opposite to the other side wall in the box body. A first discharging passageway is formed in the side wall, corresponding to a discharge end of the first screening plate, of the box body, and the discharge end of the first screening plate is exposed out of the first discharging passageway. A second discharging passageway is formed in the side wall, corresponding to a discharge end of the second screening plate, of the box body, and the discharge end of the second screening plate is exposed out of the second discharging passageway. According to the soil remediation and screening device provided by the invention, the screening effect is remarkable, the blocking phenomenon is avoided, and blocking clearing does not need to be conducted in the screening process.
