The invention belongs to the agricultural machine technology field, and particularly relates to a mulch film retrieving device and a mulch film retrieval operation machine formed thereby. The mulch film retrieving device comprises a mulch film rake mechanism, on which spiked film-collection spike-teeth (5) are densely distributed; a film-stripping band (9) is arranged on the outer side of the mulch film rake mechanism; the film-stripping band (9) is an annular transport strip-shaped body; film-stripping holes (91) which are strip-shaped are densely distributed on the transport strip-shaped body; meanwhile, the length of the annular transport strip-shaped body is greater than the outer rim length of the mulch film rake mechanism and surrounds the outer rim of the mulch film rake mechanism; and the spiked film-collection spike-teeth (5) are projected from the film-stripping holes (91) of the film-stripping band (9) to the outside of the annular transport band or retracted back to the internal of the annular transport band in a process of rotating along with the mulch film rake mechanism and the film-stripping band (9). Compared with the prior art, the mulch film retrieving device and the mulch film retrieval operation machine are simple in structure and low in manufacture cost, particularly, can effectively prevent twining of the residual film and the agricultural straws on the spike-teeth, and can greatly improve the operation efficiency.
