[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1: As Figures 1-5 and Figure 7 The technical solution shown is a surface film recycling machine. To address the problem of excessive power transmission costs, it discloses: a frame 1 and a traction frame 2 located on the right side of the frame 1; a film collection box 3 installed on the inner left side of the frame 1; a connecting axle 5 located at the bottom of the frame 1; a power transmission mechanism located at the front and rear ends of the connecting axle 5; the power transmission mechanism includes a traveling wheel 4, the inner side of which is connected to the front and rear ends of the connecting axle 5; the power transmission mechanism includes an axle bevel gear 6, the inner side of which is fixedly installed on the connecting axle. The front end of the first bevel gear 7 is meshed with the right side of the axle bevel gear 6. The middle end of the first bevel gear 7 is sleeved inside the bearing seat 8. The rear end of the bearing seat 8 is fixedly installed at the front end of the bearing connecting plate 9. The upper end of the bearing connecting plate 9 is fixedly installed at the bottom of the frame 1. The right side of the first bevel gear 7 is connected to a telescopic universal coupling 10. The right side of the telescopic universal coupling 10 is provided with a second bevel gear 11. The middle end of the second bevel gear 11 is sleeved on the lower end of the frame 1 through the bearing seat 8 and the bearing connecting plate 9.

[0036] During the operation of the residual film recycling machine, the tractor connects to the traction frame 2 of the residual film recycling machine, driving the machine frame 1 forward. During this movement, the traveling wheels 4 roll forward, and the axle bevel gear 6 on the connecting axle 5 located at the middle of the right traveling wheel 4 also rotates, thereby driving the first bevel gear shaft 7 meshing with it to rotate. The power is transmitted through the telescopic universal coupling 10 and the second bevel gear shaft 11 of the same type at the end. The first bevel gear shaft 7 and the second bevel gear shaft 11 are sleeved on the lower end of the frame 1 through the bearing seat 8 and the bearing connecting plate 9. The rotation of the second bevel gear shaft 11 drives the lower nail gear shaft 14 to rotate. The lower nail gear shaft 14 is limited by the lower nail gear plate seat 15, which can save the transmission force. The rolling force of the traveling wheels 4 is converted into the force of the rotation drive device for residual film recycling, which helps to save energy consumption.

[0037] Example 2: Figures 1-7 The technical solution shown, based on Embodiment 1, discloses the following to address the inconvenience of residual film recycling: a lower toothed plate seat 15 is installed at the bottom of the frame 1, and a residual film recycling mechanism is provided on the inner side of the lower toothed plate seat 15. The residual film recycling mechanism includes a lower toothed shaft 14, with its front and rear ends located at the bottom of the lower toothed plate seat 15. The residual film recycling mechanism also includes a lower toothed sprocket 16, which is internally fixedly installed at the front and rear ends of the lower toothed shaft 14. The front end of the lower toothed shaft 14 is sleeved on the bottom of the lower toothed plate seat 15, and its front end meshes with the right side of the second bevel gear shaft 11. A toothed rod chain 17 is meshed on the surface of the lower toothed sprocket 16, and the upper inner side of the toothed rod chain 17... The machine frame 1 is equipped with an upper toothed sprocket 19, and an upper toothed shaft 18 is provided inside the upper toothed sprocket 19. The upper toothed shaft 18 is fitted with upper toothed plate seats 20 at both ends. The lower end of the upper toothed plate seats 20 is fixedly installed on the upper end of the frame 1. A connecting ear plate 13 is fixedly installed on the surface of the toothed rod chain 17. A toothed rod body 21 is provided on the surface of the connecting ear plate 13. Toothed teeth 22 are evenly installed on the surface of the toothed rod body 21. A film conveying cover plate 23 is installed on the inner side of the frame 1 through a fixing rod 24. The lower end of the film conveying cover plate 23 corresponds to the toothed teeth 22. A film unloading plate 12 is provided on the upper end of the film conveying cover plate 23. The film unloading plate 12 is corresponding to the toothed teeth 22. The upper end of the film conveying cover plate 23 and the film unloading plate 12 are located inside the film collection box 3.

[0038] During the process of picking up residual film, the picking speed is consistent with the speed of the residual film machine's traveling wheel 4. The lower nail tooth sprockets 16 at both ends of the lower nail tooth shaft 14 are connected by the nail tooth bar chain 17, which drives the upper nail tooth shaft 18 and the upper nail tooth sprocket 19 to transmit power. When the upper nail tooth shaft 18 rotates, it is sleeved on the upper end of the frame 1 through the upper nail tooth plate seat 20. At this time, the nail tooth bar body 21 is installed on the surface of the nail tooth bar chain 17 through the connecting ear plate 13. The nail tooth body 22 installed on the nail tooth bar body 21 will hook the residual film from the ground. After the nail tooth body 22 hooks up the residual film, the residual film will enter the area formed by the nail tooth bar body 21 and the upper film conveying cover plate 23. As the nail tooth bar chain 17 drives the nail tooth bar body 21... The residual film moves through the film conveying cover plate 23 to the upper toothed roller unloading mechanism. The unloading mechanism is a curved unloading plate 12 connected to the film conveying cover plate 23. During unloading, the toothed body 22 passes through the middle of the two unloading plates 12. The residual film will detach from the toothed body 22 as the curvature of the unloading plate 12 changes and the height of the toothed body 22 protruding from the unloading plate 12 changes, and finally fall into the film collection box 3. This facilitates the recycling of the residual film, has good recycling efficiency, and is convenient for users. After the film conveying cover plate 23 is set, the residual film moves from inside the film conveying cover plate 23, and the conveying will be more stable. The dust generated here will not easily drift into the air, but will be blocked by the film conveying cover plate 23, which is beneficial to protecting the environment and preventing the spread of dust when the machine is working.

[0039] Example 3: Figure 1 , Figure 2 , Figure 8 , Figure 9 and Figure 10 The technical solution shown, based on Embodiment 2, discloses the following to address the problem of residual film accumulating and affecting the recycling space after recycling: a servo motor 25 is provided at the lower left end of the film collection box 3, and a space-saving mechanism is provided at the output end of the servo motor 25. The space-saving mechanism includes a reciprocating threaded rod 26, and the front end of the reciprocating threaded rod 26 is fixedly installed at the output end of the servo motor 25. The space-saving mechanism also includes a first movable block 27, and the interior of the first movable block 27 is threadedly connected to the reciprocating threaded rod 26. The front and rear ends of the reciprocating threaded rod 26 are rotatably installed on the left side of the film collection box 3. A support plate 28 is fixedly installed on the right side of the first movable block 27, and the support plate 28 is located against the inner wall of the film collection box 3. A second movable block 29 is fixedly installed on the upper left side of the support plate 28, and the second movable block 29 penetrates the film collection box 3. A limit rod 30 is installed through the middle of the second movable block 29, and the front and rear ends of the limit rod 30 are fixedly installed on the left side of the film collection box 3.

[0040] After the residual film falls into the inside of the film collecting box 3, the servo motor 25 is started, the starting of the servo motor 25 can drive the reciprocating threaded rod 26 to rotate, at this time the rotation of the reciprocating threaded rod 26 can drive the first movable block 27 to move, the right side of the first movable block 27 is followed by the flat plate 28 to move in the inside of the film collecting box 3, the second movable block 29 on the upper end of the left side of the flat plate 28 is installed through the limiting rod 30 and is limited, in this way, under the rotation of the reciprocating threaded rod 26, the flat plate 28 moves forward and backward along the inside of the film collecting box 3 to extrude the residual film in the inside of the film collecting box 3, in this way, the residual film is avoided to be accumulated in the inside of the film collecting box 3 due to the space, the space is not inconvenient to use, at the same time, more residual film can be stored in the inside of the film collecting box 3.
