Technical Field

[0001] The utility model belongs to the field of agricultural machinery, and particularly relates to a double-stage pick-up residual film recycling machine. Background Technique

[0002] At present, China has become the world's largest plastic film user, with the annual plastic film usage accounting for nearly half of the global total. However, due to the lack of effective recycling mechanisms and technologies, a large amount of plastic film remains in the soil, causing serious impacts on agricultural production and the ecological environment. According to investigations, in some areas, the residual amount of plastic film is as high as 36.7 grams per square meter, severely restricting the sustainable use of land. The retention and accumulation of residual plastic film in the soil not only damage the soil structure, reduce the soil permeability and water retention capacity, but also affect the activity of soil microorganisms, resulting in a decline in soil quality. In addition, the residual film may also cause mechanical obstacles to crops, affect the normal growth of roots, and thus lead to a reduction in yield.

[0003] Regarding the problem of residual plastic film in the soil, using machinery to recycle residual plastic film is the most effective method. Currently, most residual plastic film recycling machinery belongs to single-stage recycling. Although double-stage residual plastic film recycling machinery has emerged, due to the high strength and good stability of some plastic film materials, they are not easily degraded, resulting in difficult recycling; secondly, after the plastic film is used, it is often mixed with the soil and difficult to separate; furthermore, some plastic films have insufficient strength and have broken into small fragments, and existing machinery cannot recycle them.

At this time, the film lifting device 8 is inserted below the ground. The insertion depth of the film lifting device 8 can be adjusted by the pre-pressing device 2 according to the depth of the plastic film buried underground to an appropriate depth to lift the plastic film buried underground. After the adjustment is normal, the tractor can move forward normally. When the film lifting device 8 lifts the plastic film to a certain height, the film picking device 3 picks out the residual film from the soil and sends the residual film into the air inlet of the film feeding fan 4. The film feeding fan 4 blows up the larger residual film picked up by the film picking device 3 and sucks it into the film storage bin 5 to complete one picking. Then, the picking teeth 7-3 on the picking fan 7 can pick up the residual film or small piece of residual film missed by the film picking device 3, and send the residual film into the film storage bin 5 through the outlet of the fan housing 7-6 by the fan blade 7-7, so as to realize two pickings and recoveries. Under the action of wind force, it is discharged into the film storage bin 5 through the outlet of the fan housing 7-6. After two pickings, the picking recovery rate of the residual film is improved. When the film storage bin 5 is full of residual film, the oil cylinder one 5-3 extends the cylinder rod to open the tipping bin 5-5 at a certain angle. At the same time, the lower housing 5-1 is turned over under the action of the steel wire rope 5-7 to dump the residual film in the bin.
