[0036] Install the film stripping roller 3 on one side of the film collecting pin-tooth belt 4, and accurately adjust the gap between the film stripping roller 3 and the film collecting pin-tooth belt 4 to keep it at 3-5 mm, so as to ensure that the residual film can be smoothly transferred from the film collecting pin-tooth to the film stripping roller 3; install the tension positioning roller 9 on the film collecting pin-tooth belt 4, so that the trapezoidal film-picking pin-tooth 13 is uniformly distributed on the film collecting belt 12.

[0037] Reference Figure 1 , 3 , adjustment of the soil loosening and auxiliary film collecting mechanism

[0038] The soil loosening device 7 is installed below the preparation rack 1 near the front end of the film collecting pin-tooth belt 4. According to the degree of soil compaction and the condition of residual film, select the appropriate soil loosening tooth tip structure and tooth handle cross-sectional shape, for example, in the area where the soil is seriously compacted, the soil loosening device 7 with hard alloy material tooth tip and rectangular solid cross-section tooth handle can be selected to enhance the soil breaking ability. Adjust the gap between the soil loosening tooth tip and the film collecting pin-tooth belt 4, generally 2-3 cm, to ensure that the soil loosening process can effectively loosen the soil without hindering the normal work of the film collecting pin-tooth.

[0039] Reference Figure 1 , 5 , 6, preparation of the impurity removal and residual film treatment mechanism

[0040] The impurity removal device 6 is installed on one side of the film collecting pin-tooth belt 4, and the power source connected to the spiral conveying shaft mechanism of the impurity removal device 6 is started. Check whether the rotation direction of the spiral conveying shaft is correct, whether the rotation is smooth, and whether there are abnormal noises or jamming phenomena. According to the types and contents of impurities commonly found in residual film recycling operations, the initial speed and pitch of the spiral conveying shaft mechanism are set, such as setting the speed to 100-120 rpm and the pitch to 5-8 cm in the case of more impurities and larger particles.

[0041] The film feeding fan 10 is installed behind the film stripping roller 3 on the preparation rack 1. The fan left shaft seat 22 and the fan right shaft seat 24 are fixed on the rack, the fan housing 23 and the fan blade shaft 25 are installed, the rotation of the fan blade shaft 25 is ensured to be flexible, the adjustable flow guide structure of the fan housing 23 can work normally, the power source connected to the film feeding fan 10 is started, the wind speed and direction are checked, the wind speed can be adjusted within the range of 5-15 m / s, the wind direction can be adjusted within the range of ±30°, the height of the film feeding fan 10 is adjusted to match the position of the film stripping roller 3 and the subsequent film collecting device, and the residual film can be smoothly transported.

[0042] The spike belt impurity removal device 15 is installed between the film collecting spike belt 4 and the film feeding fan 10. The impurity removal direction switching device is flexible and reliable, and can be manually switched. The accuracy of the change in the impurity removal direction is observed, and the size and shape of the two impurity removal openings are adjusted. The initial setting is suitable for the removal of common impurities, such as an impurity removal opening width of 5-10 cm and a height of 3-5 cm. The shape can be adjusted according to the characteristics of the impurities, such as appropriately adjusting the width of the impurity removal opening for long strip-shaped impurities.

[0043] Working principle: First, start the power source, the main transmission 2 drives the film collecting spike belt 4 to start rotating, and the running condition of the film collecting spike belt 4 is observed. The speed should be stable at 20-30 rpm. According to the distribution of residual film in the working site, the inclination angle of the film collecting spike belt 4 is adjusted by the tensioning roller 5. For example, if the residual film is concentrated on one side, the inclination angle is adjusted to 5-10 degrees to the side to improve the film collecting efficiency. As the device advances, the soil loosening device 7 starts to work. The soil loosening tines are inserted into the soil and loosen the soil according to the pre-set depth, so that the residual film is separated from the soil and is easily picked up by the film collecting spike belt 4. The relative motion relationship between the soil loosening device 7 and the ground and the film collecting spike belt 4 during operation is that when the trapezoidal film picking spike 13 on the film collecting spike belt 4 rotates to the position of the film collecting ground roller 8 below the machine, it contacts the residual film in the loosened soil and picks up the residual film. During the film collecting process, the loosening depth and frequency of the soil loosening device 7 are adjusted in a timely manner according to the soil hardening condition and the residual film adhesion condition to ensure that the residual film can be easily picked up. The picked-up residual film moves upward with the film collecting spike belt 4. When the trapezoidal film picking spike 13 rotates to the position of the film stripping roller 3, the trapezoidal film picking spike 13 is retracted into the film stripping roller 3. Under the action of the special texture on the surface of the film stripping roller 3, the residual film is separated from the trapezoidal film picking spike 13 and remains on the surface of the film stripping roller 3. At this time, the screw conveying shaft mechanism of the impurity removal device 6 continues to work. According to the real-time condition of the impurities on the residual film and the position relationship between the impurity removal device 6 and the film collecting spike belt 4, the speed and pitch of the screw conveying shaft mechanism are further adjusted to separate and transport the impurities in the residual film to the impurity removal opening for removal. The film feeding fan 10 is started, and the speed, direction and height of the fan are adjusted to ensure that the residual film can be smoothly transported to the rear film collecting device. The airflow blown by the fan transports the residual film after film stripping to the rear film collecting device, and further blows the impurities in the residual film away to improve the cleanliness of the residual film. During the transportation process, the spike belt impurity removal device 15 manually or automatically switches the impurity removal direction according to the impurity removal condition, adjusts the size and shape of the impurity removal opening, and effectively removes the impurities to the two sides or one side of the machine to prevent the impurities from re-mixing into the residual film or entering the film feeding fan 10 and other components to cause damage.

[0044] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
