The invention relates to the field of double-rope grab buckets, in particular to a self-cleaning type double-rope and multi-valve grab bucket based on a parallel mechanism. The self-cleaning type double-rope and multi-valve grab bucket based on the parallel mechanism comprises an upper supporting beam, supporting ropes, brace rods, a lower supporting beam, bucket valves, pulleys, an opening and closing belt and a cleaning-up device. The cleaning-up device comprises a rotary table, positioning boards, edge rotation gears, a motor, a rotary board, rotary board air cylinders, cleaning-up air cylinders, swirling air cylinders and cleaning-up boards, wherein the rotary board is located below the rotary table; the tops of the rotary board air cylinders are hinged to the lower end face of the rotary table; the bottoms of the rotary board air cylinders are hinged to the upper end face of the rotary board; the tops of the cleaning-up air cylinders are hinged to the lower end face of the rotary board; the tops of the swirling air cylinders are hinged to the lower end face of the rotary board; the bottoms of the swirling air cylinders are hinged to the upper portions of the cleaning-up air cylinders; the inner sides of the cleaning-up boards are hinged to the tops of the cleaning-up air cylinders. The mass, increased when the grab bucket carries dirt, of the grab bucket can be reduced effectively; the power consumption of the motor is reduced; the grab bucket is protected and is not prone to being corroded.
