DETAILED DESCRIPTION

[0032] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0034] A diaphragm disc 5 is mounted on the frame 1 behind the vibrating shovel 43, a cleaning brush 6 is mounted on the frame 1 behind the diaphragm disc 5, cleaning wheel shafts 12 are mounted on both sides of the frame 1 where the cleaning brushes 6 are mounted, a belt 28 is mounted on the cleaning wheel shaft 12, and a cleaning brush 6 is fixed on the belt 28. The belt 28 rotates, driving the cleaning brush 6 to move, and brushing the impurities on the membrane surface into the furrow on one side. The frame 1 behind the cleaning brush 6 is provided with a film rolling device cooperating with the film lifting shovel 19, and the film rolling device includes two film rolling rollers 15, and the two film rolling rollers 15 are sleeved with the same film rolling inner shaft 22, and the opposite ends of the two film rolling rollers 15 are provided with baffles 29, and the film rolling rollers 15 are provided with square holes, and the film rolling inner shaft 22 and the film rolling roller 15 are square shafts, and the middle part of the film rolling inner shaft 22 is a round shaft, and the film rolling inner shaft 22 is hingedly provided with film picking needles 16 at intervals, and the film picking needles 16 are movably provided with a sliding sleeve 24, and the sliding sleeve 24 Pins 26 are fixedly installed on both sides, a hole 27 is provided on the film rolling roller 15 for extending or retracting the film picking needle 16, a connecting plate 25 is provided at the hole 27, and the connecting plate 25 is pin-connected with the pin 26. A cantilever 13 is movably installed in the middle of the film rolling inner shaft 22, and a distance sensor 17 is installed at the lower part of the cantilever 13. An electric push rod 18 is installed between the two cantilevers 13 and the frame 1, and the electric push rod 18 and the distance sensor 17 are connected through a controller, which can be a PLC controller or a Honeywell controller. The upper end of the cantilever 13 is movably connected to the transmission shaft 9 installed on the frame 1, and scraper frames 14 are clamped on both sides of the transmission shaft 9. The lower end of the scraper frame 14 is equipped with a scraper plate 23, which is mounted on the film rolling roller 15. The scraper plate 23 is equipped with a driving device for the scraper plate 23 to slide along the film rolling roller 15. The driving device includes hydraulic cylinders 11 close to both sides of the transmission shaft 9, and one end of the two hydraulic cylinders 11 is fixed with a mounting seat 30, which is rotatably connected to the transmission shaft 9 through a bearing. The piston ends of the two hydraulic cylinders 11 are connected with push-pull rods 21, and the push-pull rods 21 are fixedly connected to the corresponding side scraper frames 14.

[0035] The power transmission of the utility model is as follows: an idler wheel 10 is installed in the middle of the transmission shaft 9, a film winding wheel 7 is installed in the middle of the film winding inner shaft 22, and chain transmission is used between the film winding wheel 7 and the idler wheel 10, between the idler wheel 10 and the driving shaft 8, between the driving shaft 8 and the transmission 3, and between the transmission 3 and the cleaning wheel shaft 12.

[0036] When the residual film recycling machine is working in the field, the power input shaft of the transmission 3 is connected to the rear output power shaft of the tractor through a cross universal joint. When working, the residual film recycling machine is pulled by the tractor, the drive shaft 8 rotates, driving the eccentric wheel 41 to rotate, and the eccentric connecting rod 42 drives the vibrating shovel 43 to loosen the soil and impurities on and under the ground film, and the cleaning brush 6 is used to brush the impurities on the film surface to the side furrow, so that the film shovel 19 can shovel up the complete and clean ground film. The drive shaft 8 drives the film rolling roller 15 and the film rolling inner shaft 22 to rotate synchronously through the chain drive, and at the same time, the film picking needle 16 on the film rolling roller 15 picks up the ground film scooped up by the film picking shovel 19 and wraps it around the film rolling roller 15, completing the film rolling operation process.

[0037] As the ground film on the film rolling roller 15 continues to increase, the distance sensor 17 detects that the distance between the film roll of the film rolling roller 15 and the ground is reduced, and then transmits a signal to the controller. The controller controls the electric push rod 18 to push the cantilever 13 to rotate around the transmission shaft 9. When the cantilever 13 rotates, it drives the film rolling roller 15, the film scraping frame 14 and the hydraulic cylinder 11 to rotate synchronously, thereby controlling the distance between the film rolling roller 15 and the ground to prevent congestion during the film rolling process.

[0038] When the film roller 15 is fully rolled up with ground film, the hydraulic cylinder 11 is activated. When the film scraper 23 is pulled out axially along the film roller 15 under the action of the hydraulic cylinder 11, the film roller 15 and the film inner shaft 22 are relatively displaced under the action of the ground film friction force. Since the connecting plate 25 at the hole 27 on the film roller 15 and the sliding sleeve on the film picking needle 16 slide below the surface of the film roller 15, it is convenient for the film scraper 23 to scrape the ground film off the film roller 15. When the ground film is unloaded, the film scraper 23 is retracted. At the same time, when the film scraper 23 contacts the baffle 29 on the film roller 15, the film roller 15 is pulled back to its original position, and the film picking needle 16 extends out of the hole 27.
