For the convenience and firmness of film rolling by the two cone rolls, a film rolling tooth mechanism is arranged on the left cone roll 900 and the right cone roll 901, and the film rolling tooth mechanism comprises film rolling teeth 902 and film rolling tooth fixing components. As shown in fig. 4-5, the film rolling teeth fixing assembly includes a magnet 9133, an upper sleeve 9131 and a lower sleeve 9132, a first sleeve head 9134 of the upper sleeve 9131 is adapted to the magnet 9133, and a second sleeve head 9135 of the lower sleeve 9132 is adapted to the first sleeve head 9134 of the upper sleeve 9131.
The film winding teeth 902 are inserted into the sleeve holes of the upper sleeve 9131 and the lower sleeve 9132. The left conical roller 900 and the right conical roller 901 are provided with mounting holes 912 matched with the upper sleeve 9131 and the lower sleeve 9132, the mounting holes 912 are arranged in the radial directions of the left conical roller 900 and the right conical roller 901, film rolling teeth 902 are convenient to roll films, and the magnets 9133 are arranged in the central axis directions of the left conical roller 900 and the right conical roller 901, so that the film rolling teeth 902 at two sides are prevented from being influenced by different lengths of the film rolling teeth 902.
The film rolling teeth 902 are inserted into the sleeve holes, and the two insertion ends are sucked by the magnets 9133, so that falling off in the film rolling process can be effectively prevented, and the film rolling teeth are convenient to pull out. When the film is unloaded, the film rolling teeth 902 are pulled out, and then the pull rod 905 is pulled to unload the film.
In this embodiment, the upper sleeve 9131 and the lower sleeve 9132 are connected by threads, the first sleeve head 9134 of the upper sleeve 9131 is provided with external threads, the second sleeve head 9135 of the lower sleeve 9132 is provided with internal threads adapted to the external threads, and the magnet 9133 is fixed between the two sleeve heads. The two sleeve heads are in threaded connection, so that the distance between the two sleeve heads can be conveniently adjusted to adapt to magnets with different thicknesses, and meanwhile, the magnets can be conveniently replaced.
The mulching film recovery device is further provided with a film collecting box assembly, as shown in fig. 7, the film collecting box assembly comprises a film collecting box 7 with an openable bottom plate 701 and a film guiding plate 8 hinged on the film collecting box 7, one end of the film guiding plate 8 is pressed on a roller 601 of the eccentric roller pickup device 6 through a tensioning spring 704, and two free ends of the tensioning spring 704 are respectively hung on the bottom of the film guiding plate 8 and a side plate 700 of the film collecting box 7. The film collecting box 7 is arranged below the cone roller film rolling device 9.
The film collecting box 7 is used for collecting fragments of the mulching film which cannot be rolled up on the left and right cone rolls, and can also be used for containing residual film rolls which are dismounted from the left and right cone rolls. In practical field experiments, it is found that when the drum 601 of the eccentric drum pick-up device 6 conveys films to the conical roller, a film clamping phenomenon often occurs between the drum 601 and the film guiding plate 8, so that the film guiding plate 8 is tightly pressed on the drum 601 of the eccentric drum pick-up device 6 through the tension spring 708, and the phenomena of film clamping of the film guiding plate 8 and the like can be effectively prevented and avoided, so that the subsequent film rolling effect is ensured. The eccentric drum pickup device 6 is already of the prior art and will not be described in detail here.
The film-forming profiling device comprises at least one group of film-forming profiling monomers 5, as shown in fig. 8-9, wherein the film-forming profiling monomers 5 comprise film-forming arc teeth 500, a vertical adjusting component and a horizontal adjusting component.
