AI Technical Summary
The existing residual film harvester's picking mechanism cannot effectively adapt to the mixed use of long and short nails, resulting in poor film removal effect.
Design a stripping roller that uses stripping discs A and B of different diameters to alternately form a wavy surface. The roller removes residual film from the pick-up teeth through the gap, adapts to pick-up teeth of different lengths, and has a contour stripping function.
A simple picking mechanism has been developed that can adapt to the use of a mixture of long and short nails, thus improving the demolding effect.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of agricultural machinery, specifically relating to a film stripping roller used on a residual film recycling machine. Background Technology
[0002] After crops are planted, the plastic film needs to be recycled. For example, CN215648104 discloses a residual film picking mechanism. This picking mechanism uses a belt to drive the nail teeth to pick up the residual film, and finally uses the film removal wheel above to remove the film, that is, to remove the residual film from the picking nail teeth.
[0003] Currently, an improved picking mechanism has emerged, which picks up nails of different lengths, including long nails and short nails. Existing stripping rollers cannot achieve the same stripping effect. Therefore, this application proposes a simple picking mechanism that can adapt to the mixed use of long and short nails. Summary of the Invention
[0004] The technical problem to be solved by this utility model is a simple picking mechanism that can adapt to the mixed use of long and short nails.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a stripping roller used on a residual film harvester, comprising a fixed shaft 11, wherein a stripping disc is provided on the surface of the fixed shaft 11, the fixed shaft 11 and the stripping disc are arranged perpendicularly to each other, the stripping disc is divided into a stripping disc A13 and a stripping disc B14, the stripping disc A13 and the stripping disc B14 have different diameters, and a gap 15 is provided between two adjacent stripping discs, that is, there is a gap 15 between stripping disc A13 and an adjacent stripping disc A13 or an adjacent stripping disc B14.
[0006] In actual use: When the pick-up teeth pass through the gap 15 between the stripping discs, the stripping discs push the residual film out of the teeth, achieving film removal. Because the stripping discs A13 and B14 have different diameters, they can remove residual film at different heights. This not only adapts to pick-up teeth of different lengths but also provides a certain degree of contouring during film removal. The overall surface of the stripping roller forms a wave shape, achieving a contouring stripping effect.
[0007] As an improvement, the stripping discs A13 and B14 are arranged sequentially from one end of the fixed shaft 11 to the other end, and the number of stripping discs A13 arranged consecutively is 1-M, and the number of stripping discs B14 arranged consecutively is 1-N, where M and N are positive integers.
[0008] In actual use: the setting of stripping discs A13 and B14 can be determined as needed, that is, M consecutive stripping discs A13 and N consecutive stripping discs B14 can be arranged alternately to achieve a wavy surface effect.
[0009] As an improvement, M and N have the same value, which is 3-6.
[0010] As an improvement, the value of M is greater than the value of N, and the value of M or N is between 3 and 6.
[0011] As an improvement, the value of M is larger than the value of N, and the value of M or N is between 3 and 6.
[0012] As an improvement, the gap 15 between the stripping discs may be the same or different in size.
[0013] Compared with the prior art, this utility model has the advantages of simple structure, pick-up mechanism that can adapt to the mixed use of long and short nails, and good demolding effect. Attached Figure Description

[0019] The following embodiments further illustrate the above-described content of the present invention in detail. Obviously, the described embodiments are merely a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0020] Example 1: Refer to Figure 1-2 This is a schematic diagram of the structure of Embodiment 1 of the present utility model. This embodiment discloses a stripping roller used on a residual film harvester, including a fixed shaft 11. A stripping disc is provided on the surface of the fixed shaft 11. The fixed shaft 11 and the stripping disc are arranged perpendicular to each other. The stripping disc is divided into stripping disc A13 and stripping disc B14. The diameters of stripping disc A13 and stripping disc B14 are different. A gap 15 is provided between two adjacent stripping discs, that is, there is a gap 15 between stripping disc A13 and adjacent stripping disc A13 or adjacent stripping disc B14.
[0021] The stripping discs A13 and B14 are arranged sequentially from one end of the fixed shaft 11 to the other end, and the number of stripping discs A13 arranged consecutively is 1-M, and the number of stripping discs B14 arranged consecutively is 1-N, where M and N are positive integers.
[0022] First, set a 3M stripping disc A13 at one end of the fixed shaft 11, then set N stripping discs B14, and so on. The stripping discs A13 and B14 are arranged symmetrically from left to right.
[0023] Example 2: Refer to Figure 3-4 This is a schematic diagram of the structure of Embodiment 2 of the present invention. Compared with Embodiment 1, the difference in this embodiment is that N stripping discs B14 are first set from one end of the fixed shaft 11, followed by M stripping discs A13, and so on. Furthermore, the stripping discs A13 and B14 are arranged symmetrically from left to right.
