[0002] In tobacco planting, the planting period is generally in mid-to-late April. In order to ensure the growth of seedlings, ground film is needed to be covered. Ground film can have the functions of heat preservation, water retention, and moisture retention, and can increase the crop yield in arid and cold areas. However, after the ground film is used up, the waste ground film needs to be recycled to prevent it from polluting the environment. The current recycling is mainly done manually, which is time-consuming, inefficient and has high labor costs. At the same time, the existing ground film recycling equipment cannot remove the soil on the surface of the ground film. When recycling the ground film, a large amount of soil will be carried into the recycling box, increasing the workload of subsequent processing procedures.

[0003] At present, the utility model with patent number CN205987711U discloses a ground film recovery device and a ground film recovery machine constituted by it. When collecting the ground film, this scheme mainly uses thorny film-holding nail teeth to prick the ground film, and then uses a film stripping belt to peel off the ground film and make it fall into a film collecting box. When collecting the ground film, the soil and crops on it will not be processed. Therefore, a large amount of soil will be brought up on the upper and lower surfaces of the ground film. The ground film mixed with a large amount of soil will quickly fill up the film collecting box, resulting in the need for staff to frequently clean the film collecting box, affecting work efficiency. At the same time, the film-lifting mechanism is a comb-like object composed of multiple side-by-side spring teeth. This comb-like object will accumulate soil when working, so it needs to be cleaned every once in a while, which is not very convenient to use. Utility Model Content
