Automatic cable recovery device for engineering pile machine

The invention relates to an engineering pile machine cable automatic recovery device which comprises a recovery device shell, a pair of feeding rollers, a cleaning assembly, a lifting roller, a first winding roller and a second winding roller. The recovery device shell is provided with a first cable outlet and a second cable outlet. The pair of feeding rollers is arranged at a first cable outlet of the recovery device shell; the cleaning assembly is arranged at the first cable outlet; the liftable roller can be vertically lifted so as to adjust the tension of the cable; and the first winding roller and the second winding roller are arranged in the recovery device shell through torsion springs, and a cable sequentially penetrates through the position between the feeding rollers and the surface of the liftable roller and is sequentially wound on the first winding roller and the second winding roller. Compared with the prior art, the cable recovery device has the advantages that the cable recovery work can be au
