Comprising a machine frame and a film lifting and soil unloading part which is arranged on the machine frame and used for turning soil pressed above a mulching film out of the film surface during film lifting. The film rolling mechanism is rotatably arranged on the rack and used for applying film rolling pulling force to the mulching film, and the transmission mechanism is connected with the film rolling mechanism and can be switched between a transmission state and an interruption state. According to the film uncovering machine tool, when a film is uncovered, the film uncovering and soil unloading piece can be used for uncovering a pressed mulching film and unloading film pressing soil, the film uncovering resistance is reduced, and therefore the phenomenon that the film is broken due to the fact that the resistance is too large is avoided; by means of the tension-adjustable transmission mechanism, proper tension can be adjusted according to changes of resistance and tension of the film rolling roller, film rolling tension stability is guaranteed, film breaking is avoided, and smooth film uncovering is achieved through dual control and mutual cooperation of the film uncovering soil unloading part and the tension-adjustable transmission mechanism.
