The rock and soil screening device comprises a screening box, a feeding port is formed in the upper end of the screening box, a screening net is arranged in the screening box, a vibrator is fixedly connected to one side of the lower end of the screening net, an auxiliary vibration assembly is arranged between the screening net and the screening box, and the auxiliary vibration assembly is fixedly connected with the screening box. The left end of the screening box is fixedly connected with a collecting box, and the inner wall of the collecting box is fixedly connected with a protective pad. By the adoption of the structure, when the meshes of the screening net need to be thoroughly dredged, the hole door is opened, the telescopic air cylinder is used for driving the micro air pump to extend to the lower side of the screening net, the jet head moves in a reciprocating mode, rock soil blocked in the meshes is blown upwards and rolls back into the collecting box, and the phenomenon that after the screening net is
