[0035] Among them, the frame 2 serves as a supporting structure and a connecting structure for the installation and fixing of the suspension frame 1, the scraper board 5, the anti-winding film lifting system 3 and the fan system 4. The suspension frame 1 is fixed on the frame 2, and the suspension frame 1 is used to connect the traction equipment, such as a tractor. Since the suspension frame 1 is a commonly used structure in the field, it is not described here. The scraper board 5 is fixed to the lower front side of the frame 2, and the middle part of the scraper board 5 protrudes forward. When the scraper board 5 moves forward under the traction of the traction equipment, the scraper board 5 pushes the soil covering the ground film to both sides to facilitate the subsequent film lifting action. The anti-winding film lifting system 3 includes a film lifting device 3-1 and a cutting device 3-2. The ground film is lifted by the film lifting device 3-1 and then cut into pieces by the cutting device 3-2 to facilitate the collection of the fan system 4. The film picking device 3-1 includes a film picking roller 3-1-1, a shaft sleeve 3-1-2, an end cover 3-1-11 and a film picking roller driving mechanism. The film picking roller 3-1-1 is located at the rear side of the scraper blade 5. The film picking roller 3-1-1 is provided with a running groove 3-1-3 extending in the axial direction. The inner surface of the film picking roller 3-1-1 is provided with a guide track 3-1-4. The guide track 3-1-4 is located on both sides of the running groove 3-1-3. The outer surface of the film picking roller 3-1-1 is provided with film picking teeth 3-1-5. The end cover 3-1-11 is fixed at both ends of the film picking roller 3-1-1. The shaft sleeve 3-1-2 is fixedly connected to the end cover 3-1-11. The film picking roller driving mechanism is used to drive the shaft sleeve 3-1-2 to rotate. When the film picking roller 3-1-1 rotates, the ground film is transported and wound backward. The cutting device 3-2 includes a cylindrical cam 3-2-1, a follower 3-2-2, a support shaft 3-2-3 and a support seat 3-2-4. The sleeve 3-1-2 is sleeved on the outside of the support shaft 3-2-3 and rotates relative to the support shaft 3-2-3. One end of the support shaft 3-2-3 is fixedly connected to the end of the cylindrical cam 3-2-1, and the other end of the support shaft 3-2-3 is fixedly connected to the support seat 3-2-4. A cam groove is provided on the cylindrical cam 3-2-1. The driven member 3-2-2 includes a roller 3-2-2-1, a driven seat 3-2-2-2, a rolling bearing 3-2-2-3 and a cutting knife 3-2-2-4. The roller 3-2-2-1 is rotatably connected to one end of the driven seat 3-2-2-2, the cutting knife 3-2-2-4 is fixed to the other end of the driven seat 3-2-2-2, and the rolling bearing 3-2-2-3 is rotatably connected to the middle of the driven seat 3-2-2-2 and is located at the film picking roller 3-1. -1 and the cylindrical cam 3-2-1, the roller 3-2-2-1 is located in the cam groove, the axis of the roller 3-2-2-1 is arranged along the radial direction of the circular cam, the cutting knife 3-2-2-4 extends outward from the running groove 3-1-3 and is arranged parallel to the running groove 3-1-3, the rolling bearing 3-2-2-3 is located on the inner side of two adjacent guide rails 3-1-4, and the axis of the rolling bearing 3-2-2-3 is perpendicular to the cutting knife 3-2-2-4.When the film picking roller 3-1-1 rotates, since the cylindrical cam 3-2-1 is fixed, the follower 3-2-2 will move along the cam groove on the cylindrical cam 3-2-1 under the drive of the film picking roller 3-1-1, and the follower 3-2-2 is equivalent to the film picking roller 3-1-1 making reciprocating linear motion in the walking groove 3-1-3. The roller 3-2-2-1 and the rolling bearing 3-2-2-3 can reduce friction, thereby reducing wear, extending service life, and saving energy. The fan system 4 includes a fan 4-4, a fan drive mechanism, an air inlet channel and a film collecting bag 4-5. The fan drive mechanism is used to provide power for the fan 4-4. The air inlet channel has an inlet and an outlet. The fan 4-4 has an inlet and an outlet. The bag mouth of the film collecting bag 4-5 is fixedly sleeved at the outlet of the fan 4-4. The outlet of the air inlet channel is connected to the inlet of the fan 4-4. The inlet of the air inlet channel is located behind the film picking roller 3-1-1. When the fan driving mechanism is working, it drives the fan 4-4 to work, and the ground film passes through the air inlet channel and the fan 4-4 under the negative pressure formed by the fan 4-4, and is finally collected in the film collecting bag 4-5.

While the machine is moving, the scraper blade 5 scrapes off the soil covering the ground film and transports it to both sides of the ground film, so that the ground film buried underground is exposed to the surface, the film picking teeth 3-1-5 pick up the exposed ground film and transport it backward and upward, the cutting knife 3-2-2-4 cuts off the ground film wrapped around the film picking roller 3-1-1, and the fan 4-4 sucks the picked up ground film and the ground film remaining on the surface that has not been picked up into the film collecting bag 4-5, completing the ground film recycling operation.

[0037] In order to improve the recovery effect of the ground film, the air inlet channel of this embodiment has two inlets, including a first inlet and a second inlet. The first inlet of the air inlet channel is located at the upper rear of the film picking roller 3-1-1 and faces the film picking roller 3-1-1, and is used to suck the ground film picked up by the film picking device 3-1 into the fan 4-4 through the connecting pipe device 4-3. In this embodiment, the first inlet is at an angle of 70 degrees to the ground, and those skilled in the art can also select a corresponding angle according to the actual design size of the machine. The second inlet of the air inlet channel is located behind the film picking roller 3-1-1 and faces downward, and is used to suck the ground film that has not been picked up and remains on the surface into the fan 4-4, thereby realizing the secondary recovery function of the ground film.

[0038] The air inlet channel only plays a conveying role, and those skilled in the art can select its specific shape according to actual needs. The air inlet channel of this embodiment includes a first film absorbing device 4-1, a second film absorbing device 4-2 and a connecting pipe device 4-3, and the connecting pipe device 4-3 includes an S-shaped pipeline and a vertical branch. The first film absorbing device 4-1 is fixed to one end of the S-shaped pipeline, and the other end of the S-shaped pipeline is fixedly connected to the inlet of the fan 4-4. The upper end of the vertical branch is fixed to the lower side of the S-shaped pipeline, and the second film absorbing device 4-2 is fixed to the lower end of the vertical branch. The first film absorbing device 4-1 and the second film absorbing device 4-2 are arc-shaped trumpet-shaped thin-walled structures, so that as much ground film as possible can be recovered. In this embodiment, both ends of the S-shaped pipeline and the lower end of the vertical branch are rectangular thin-walled structures of 300×200mm (outer contour), and the small mouth end of the arc-shaped trumpet-shaped thin-walled structure is a rectangular thin-walled structure of 296×196mm (outer contour), and the two are nested and connected.

[0039] In the prior art, there are many forms of the fan 4-4 drive structure, as long as it can drive the fan 4-4 to work. Specifically, the fan drive structure in this embodiment includes a fan sprocket 4-6, a second hydraulic motor sprocket 4-7, a second hydraulic motor 4-8, a second hydraulic motor seat 4-9 and a fan chain 4-10.

[0040] In the prior art, there are many forms of the driving structure of the roller, as long as it can drive the roller to rotate. Specifically, the film picking roller driving mechanism in this embodiment includes a first hydraulic motor sprocket 3-1-6, a first hydraulic motor seat 3-1-7, a first hydraulic motor 3-1-8, a transmission sprocket 3-1-9 and a transmission chain 3-1-10.

When the first hydraulic motor 3-1-8 is working, since the transmission sprocket 3-1-9 is fixed on the sleeve 3-1-2, the sleeve 3-1-2 is fixedly connected to the end cover 3-1-11, and the end cover 3-1-11 is fixedly connected to the film picking roller 3-1-1, the film picking roller 3-1-1 and the transmission sprocket 3-1-9 rotate synchronously.

[0041] More specifically, the scraper blade 5 of this embodiment is a V-shaped structure with the tip leading forward, and the cross section of the scraper blade 5 is a semicircular structure with the lower edge tangent to the ground. This structure can smoothly scrape up the soil covering the ground film and transport it to both sides of the ground film, and prevent the scraped soil from flowing back to the ground film behind the scraper blade 5 due to the movement of the machine, so that the ground film behind the scraper blade 5 is always exposed on the ground surface.

[0042] Regarding the specific form of the cam groove on the cylindrical cam 3-2-1, in this embodiment, the cam groove enables the cutting knife 3-2-2-4 to maintain the isoacceleration (parabola) motion law when moving from one side of the film picking roller 3-1-1 to the other side; and enables the cutting knife 3-2-2-4 to maintain the cosine acceleration (simple harmonic) motion law when moving back from the other side of the film picking roller 3-1-1.
