It is driven to rise and fall by a hydraulic cylinder 7 fixed to the side plate 1. The mechanism includes a soil-separating film pressing roller 8 and a soil-feeding roller 9. The soil-separating film pressing roller 8 is rotatably positioned between the two side plates 1, with several soil-separating holes 10 on its side wall and film pressing rings 19 near both ends. The soil-feeding roller 9 is located at both ends of the soil-separating film pressing roller 8. A film cutting knife 11 is located between the two side plates 1 and on the side of the film pressing mechanism away from the film-laying roller 6. It is driven to rise and fall by a hydraulic cylinder 12 fixed to the side plate 1.
