[0002] Film laying and sowing operations have been widely used in central and western my country. However, while the film has positive significance in terms of heat preservation, moisture conservation, and water conservation during the growth of crops, its non-degradable nature also causes serious pollution to the land. Therefore, recycling the film is a necessary link to reduce the increase in land film. Mechanical recycling of residual film is still an important measure to control residual film pollution.

[0003] In recent years, the mechanization of residual film recycling has become increasingly advanced, but it is still in its early stages. Currently, the methods for picking up residual film generally include drum type and chain rake type. These methods have problems such as incomplete film removal or too complex equipment structure, high cost, short service life, and inconvenient maintenance. Utility model content:

[0006] Furthermore, the second connecting plate is provided with a plurality of "V"-shaped grooves corresponding to and connected with the spacing grooves, and the two side walls of the "V"-shaped grooves can contact with the film picking teeth.

[0007] Furthermore, the first connecting plate is provided with an avoidance groove for the membrane picking teeth to pass through.

[0015] like Figure 1-Figure 4 As shown, the utility model describes a film stripping mechanism for a ground film recovery device, which includes a film stripping roller 1 and a film stripping cover 2. The film stripping roller 1 is provided with a film picking tooth 11, and the film stripping cover 2 includes a plurality of "C"-shaped plates 21 arranged at intervals along the axial direction, the "C"-shaped plates 21 cover the periphery of the film stripping roller 1, and adjacent "C"-shaped plates 21 form a spacing groove 201 for the film stripping teeth 11 to rotate through, the lower end of the "C"-shaped plate 21 is set as a film stripping end, and the upper end of the "C"-shaped plate 21 is set as a film stripping end, the film stripping end is connected by a first connecting plate 22, and the film stripping end is connected by a second connecting plate 23, and the film stripping tooth 11 is passed out from the inside of the "C"-shaped plate 21 to the outside and rotates along the spacing groove 201 as the film stripping roller 1 rotates at the film stripping end, and is passed into the inner side of the "C"-shaped plate 21 from the outside of the "C"-shaped plate 21 to the inside as the film stripping roller 1 rotates at the film stripping end. In this embodiment, the film-starting end of each "C"-shaped plate 21 is connected and fixed to the first connecting plate 23 by screws and nuts through a connecting piece 24. Of course, the film-starting end of the "C"-shaped plate 21 and the edge of the first connecting plate 23 can also be directly opened and connected and fixed by screws and nuts.

[0016] When the film picking teeth 11 pass through the outside from the inside at the film lifting end, the ground film is picked up and carried upward along the "C"-shaped plate 21. When it reaches the film stripping end, the film picking teeth 11 rotate with the film lifting roller 1 and will pass into the "C"-shaped plate 21 from the end of the spacing groove 201, so that the ground film is separated from the film picking teeth 11 and is held above the second connecting plate 23 and is pulled and transmitted to the conveyor belt or collection point behind, completing the film lifting and stripping process.

[0017] The first connecting plate 22 is provided with an avoidance groove 221 for the film picking teeth 11 to pass through; the second connecting plate 23 is provided with a plurality of "V"-shaped grooves 231 corresponding to and connected with the spacing grooves 201, and the two side walls of the "V"-shaped grooves 231 can contact the film picking teeth 11 or at least the ends of the film picking teeth 11 contact the two side walls of the "V"-shaped grooves 231 to form a scrape, so as to facilitate the scraping of the ground film on the film picking teeth 11 and make the ground film detach from the film picking teeth 11 more thoroughly. In this embodiment, the "C"-shaped plate 21, the first connecting plate 22, and the second connecting plate 23 can all be made of wear-resistant nylon plate materials to improve wear resistance and service life. The second connecting plate 23 and multiple "C"-shaped plates 21 are first connected as a whole or integrally formed, and after being arranged with the film-forming roller 1 and the film-picking teeth 11, they are connected and fixed through the first connecting plate 22, and fixedly connected to the equipment crossbeam through the first connecting plate 22 and the second connecting plate 23 at both ends; after assembly, the "C"-shaped plate 21, the first connecting plate 22, and the second connecting plate 23 are not in contact with the film-forming roller 1, and are relatively suspended;

[0018] The first connecting plate 22 and the second connecting plate 23 are provided with connecting seats 202 at both ends, so as to be connected with the cross beam of the recycling equipment for installation. In this embodiment, the connecting seat 202 is connected with the external cross beam by a U-shaped screw, and of course it can also be connected by other means.

[0019] Furthermore, the film-lifting roller 1 has two end plates 12, and the outer edges of the end plates 12 are respectively provided with a plurality of film-lifting tooth tubes 13 parallel to the roller axis, and the film-lifting teeth 11 are evenly distributed on the film-lifting tooth tubes 13 along the radial direction. The film-lifting teeth 11 can be arranged on the film-lifting tooth tubes 13 by welding, threaded connection, pin connection, etc., and the connection between the film-lifting tooth tubes 13 and the end plates 12 can also be a detachable connection, which is convenient for replacing or maintaining damaged film-lifting teeth.

[0020] In summary, the demolding mechanism of the utility model has the advantages of being simpler overall, low cost, long service life, and easy maintenance.
