[0038] like Figure 1-Figure 10 As shown, this embodiment provides a wide film recycling machine, including a machine body 1, the machine body 1 has structures such as rollers and a traction frame 8, and the machine body 1 is sequentially provided with a film removing device 2, a residual film picking device 3, a residual film conveying device 4, a residual film bundling device 5 and a leaking rake tooth device 6, and the residual film bundling device 5 is equipped with a rope feeding device 7, and the rope feeding device 7 is used to supply bundling rope to the residual film bundling device 5.

[0039] The film-lifting device 2 includes a shovel frame 21 and a film-lifting shovel 22. The shovel frame 21 is installed at the front end of the machine body 1. The film-lifting shovel 22 is installed on the shovel frame 21. The film-lifting shovel 22 is arranged obliquely upward. The film-lifting shovel 22 is used to pick up the residual film in the land together with the adhered soil blocks and plant roots, and then send them to the lower position of the residual film picking device 3. The residual film picking device 3 picks up the residual film and its adhered objects and transfers them to the residual film conveying device 4. The residual film conveying device 4 conveys the residual film to the residual film bundling device 5.

One side of the rope feeding frame 71 is provided with a placement shaft 74 for placing the baling rope. The rope winding box 72 is installed on the rope feeding frame 71. The rope feeding frame 71 is provided with a roller conveying mechanism 75. The roller conveying mechanism 75 is used to guide the baling rope to the residual film baling device 5. The cutting mechanism 73 is used to cut the baling rope.

[0044] In order to facilitate the feeding of the baling rope into the roller conveying mechanism 75, the rope winding box 72 is provided with a guide mechanism, and the guide mechanism is used to guide the baling rope on the placement shaft 74 to the roller conveying mechanism 75. In some embodiments, the guide mechanism includes a guide ring 76, a guide plate 77 and a guide block 78, and the guide ring 76 and the guide plate 77 are both arranged on the rope winding box 72, and the guide block 78 is slidably matched with the rope winding box 72, and a rope guide hole 79 is opened on the guide block 78. The baling rope passes through the guide ring 76, the guide plate 77 and the rope guide hole 79 in sequence and is then fed into the roller conveying mechanism 75, and the guide block 78 can slide along the rope winding box 72 to facilitate the adjustment of the position of the rope guide hole 79.

[0045] In this embodiment, the residual film picking device 3 includes a film picking tooth 31 and a picking roller 32. The film picking tooth 31 is arranged inside the picking roller 32. The picking roller 32 is provided with a through hole for the film picking tooth 31 to enter and exit. The film picking tooth 31 in the picking roller 32 can extend from the through hole and pick up the residual film on the film lifting device 2 and then remain in the extended state, and then return to the picking roller 32 through the through hole to transport the residual film to the residual film transporting device 4. The residual film picking device 3 also includes a central shaft 33 rotatably connected to the body 1, a track plate 34 arranged at both ends of the picking roller 32, and a rotating assembly; the central shaft 33 is fixedly connected to the picking roller 32, the track plate 34 is fixedly connected to the body 1, and the track plate 34 is provided with an eccentric track 35.

[0046] The central shaft 33 is fixedly connected to the pickup roller 32, for example, the central shaft 33 is fixedly connected to the pickup roller 32 via a connecting rib 36. Each of the rotating components includes a first connecting shaft 39, a second connecting shaft 37 corresponding to the first connecting shaft 39, and a connecting bar 38. Both ends of the first connecting shaft 39 are provided with sliders that cooperate with the eccentric track 35. The first connecting shaft 39 is provided with a plurality of film picking teeth 31 arranged at intervals along the axial direction of the first connecting shaft 39. Both ends of the second connecting shaft 37 are connected to the pickup roller 32. One end of the connecting bar 38 is connected to the first connecting shaft 39, and the other end is hinged to the second connecting shaft 37. There are a plurality of rotating components, and the plurality of rotating components are arranged equidistantly along the circumference of the central shaft 33, and the number of film picking teeth 31 in each rotating component corresponds to each other.

[0047] The utility model realizes that the film picking teeth 31 can extend from the lower end of the picking roller 32 and pick up the residual film on the film shovel 22 and then maintain the extended state, and move from the lower end, front end, upper end to the rear end of the picking roller 32 in sequence. The film picking teeth 31 located at the rear end of the picking roller 32 are retracted into the picking roller 32 through the through hole. At the same time, the force is reasonable and the operation is more stable, which ensures the stability of the overall movement of the film picking and conveying residual film. At the same time, because the film picking teeth 31 run from the lower end, front end, upper end to the rear end of the picking roller 32, the residual film can be thrown on the residual film conveying device 4, which is convenient for the subsequent separation of residual film and debris.

[0048] The residual film conveying device 4 includes a conveying roller assembly 41 and a conveyor belt 42. The conveyor belt 42 is installed on the conveying roller assembly 41. A plurality of flexible scrapers 43 are arranged at intervals on the conveyor belt 42. The flexible scrapers 43 protrude from the outer surface of the conveyor belt 42 to scrape away the residual film on the residual film picking device 3.

[0049] When the flexible scraper 43 contacts the film picking teeth 31 at the rear end of the pickup roller 32, the flexible scraper 43 can scrape off the residual film and debris left on the film picking teeth 31 and the pickup roller 32, ensuring that the film picking teeth 31 can effectively pick up the residual film when extending in the next step, thereby improving the recovery rate and efficiency of the residual film and preventing the residual film or debris from clogging the holes on the pickup roller 32. In addition, since the flexible scraper 43 protrudes from the outer surface of the conveyor belt 42, it can also prevent the residual film or debris separated during the conveying process from returning to the feed end of the conveyor belt 42, further improving the residual film recovery efficiency.

[0050] The residual film bundling device 5 includes a fixed part 51 and a movable part 52 arranged on the body 1, and an opening and closing actuator 53 for controlling the opening and closing of the fixed part 51 and the movable part 52 is arranged between the fixed part 51 and the movable part 52. When the fixed part 51 and the movable part 52 are closed, a closed bundling chamber is formed. The fixed part 51 and the movable part 52 are both provided with a roller assembly 54 for compressing and bundling the residual film. The opening and closing actuator 53 adopts a hydraulic cylinder, and the collected residual film is located in the bundling chamber. When the residual film reaches a certain density, the opening and closing actuator 53 controls the fixed part 51 and the movable part 52 to open and discharge the compressed and bundled residual film. In order to improve the closing effect of the fixed part 51 and the movable part 52, a closing locking device 55 is arranged between the fixed part 51 and the movable part 52. The closing and locking device 55 includes a locking hook and a locking shaft, which are respectively arranged on the fixed part 51 and the movable part 52. The locking hook is equipped with a driving mechanism. After the fixed part 51 and the movable part 52 are closed, the locking hook and the locking shaft are locked with each other.
