The invention discloses a quantitative recovery apparatus for power cables. The quantitative recovery apparatus comprises a base, wherein a weighing apparatus is fixedly arranged on the base; a main frame is mounted on a weighing platform of the weighing apparatus; a rotary sleeve is rotationally mounted on the main frame; hinged swing arms are uniformly and annularly arranged at the lower part of the rotary sleeve; the middle parts of the swing arms are bent towards the center of the rotary sleeve; a center shaft is inserted in the rotary shaft in an axial direction glidingly; a conical block with a downward sharp end is fixedly arranged at the lower end of the center shaft; tracks corresponding to the swing arms are uniformly formed in the conical surface of the conical block; extension blocks which extend to the tracks are fixedly arranged on the middle parts of the swing arms; matching parts which can only move along the tracks are mounted on the end parts of the extension blocks; the main frame is provided with a main power apparatus and a lifting apparatus; the base is also provided with a cutting apparatus; and the quantitative recovery apparatus also comprises a starting-stopping apparatus which is used for controlling the starting and stopping of the main power apparatus and the lifting apparatus. By adoption of the quantitative recovery apparatus, waste cables can be wound in bunches automatically and tightly; the cables can be bundled up easily; the cables can be weighted automatically and precisely; automatic material throwing can be carried out; and therefore, the quantitative recovery apparatus is high in automatic degree, simple to operate and can be operated by one person.
