[0002] Dryland farming techniques, primarily based on plastic film mulching, have played a significant role in increasing farmers' income and agricultural production. However, with the continuous expansion of the mulching area and the increasing use of plastic film year by year, the residual years in the soil can reach decades or even centuries due to the non-degradable polyethylene and polyvinyl chloride materials used in plastic film mulching. While bringing considerable benefits, plastic film mulching cultivation technology has also brought about various problems such as farmland environmental degradation, soil quality decline, and crop yield reduction. Manually cleaning plastic film is labor-intensive, time-consuming, physically demanding, and has low recycling efficiency.
[0003] To address the problem of residual plastic film in the soil that is difficult to remove, existing technologies involve plastic film recycling equipment, such as residual film picking and baling machines. These machines can pick up and bale residual film. However, in practical applications, after picking up the residual film, it will be stuck with a lot of soil clods, plant roots and stems and other debris. After baling, it will contain a large amount of debris, which seriously affects its subsequent reuse and disposal. Utility Model Content

Detailed Implementation
[0020] like Figure 1-5 As shown, this utility model provides a residual film dry cleaning device for a pickup machine, including a mounting frame 1, a dry cleaning drum mounted on the mounting frame 1, and a drive motor 2 mounted on the mounting frame 1. The dry cleaning drum includes fixed plates 3 mounted on the mounting frame 1, an upper arc plate 4 and a lower arc mesh 5 disposed between the fixed plates 3, a spiral guide plate 6 disposed between the fixed plates 3 and located within the upper arc plate 4 and the lower arc mesh 5, a rotating shaft 7 rotatably disposed between the fixed plates 3, rotating plates 8 respectively fixed at both ends of the rotating shaft 7, a rotating rod 9 fixed between the rotating plates 8, and a lever 1 fixed on the rotating rod 9. 0; The upper arc plate 4 and the lower arc mesh 5 are both semi-circular structures and form a cylindrical structure after being fixed together. The two ends of the rotating shaft 7 are respectively rotatably mounted on the fixed plate 3 and located on the axis formed between the upper arc plate 4 and the lower arc mesh 5. The rotating plate 8 is located inside the fixed plate 3 and rotates synchronously with the rotating shaft 7. The two ends of the rotating rod 9 are fixed on the rotating plate 8 and multiple rods are arranged around the rotating shaft 7. The rotating rod 9 is located between the spiral guide plate 6 and the rotating shaft 7 and rotates synchronously with the rotating shaft 7. The lever 10 is vertically fixed on the side of the rotating rod 9 facing away from the rotating shaft 7. The drive motor 2 is connected to the rotating shaft 7 in a transmission manner.
[0021] Mounting frame 1 is used to install this device onto the residual film picking and baling machine. The specific structure is not limited; it can be adapted to the actual structure of the residual film picking and baling machine. Drive motor 2 is fixed to mounting frame 1, with its output end fixed to one end of rotating shaft 7, used to drive the rotating shaft 7 to rotate. There are two fixing plates 3, fixed relative to each other on mounting frame 1, with both ends of rotating shaft 7 rotatably connected to fixing plates 3. Upper arc plate 4 is a semi-circular metal plate, and lower arc mesh 5 is a semi-circular metal mesh, forming a cylindrical structure after fixing. Spiral guide plates 6 are fixed at both ends to fixing plates 3; multiple sets can be set as needed. There are two rotating plates 8, fixed at their center to rotating shaft 7, located within the contents of fixing plates 3. There is a gap between rotating plates 8 and fixing plates 3, and rotating plates 8 rotate synchronously when rotating shaft 7 rotates. Rotating rods 9 are fixed at both ends between rotating plates 8, and multiple rods are arranged in a ring around rotating shaft 7. Rotation of rotating plates 8 drives rotating rods 9 to rotate synchronously. The lever 10 is fixed on the side of the rotating rod 9 facing away from the rotating shaft 7 and is set vertically. Multiple levers 10 are set at equal intervals along the length of the rotating rod 9.
[0022] During use, the collected residual film enters the upper arc plate 4 and the lower arc mesh 5. The drive motor 2 drives the rotating shaft 7 to rotate, which in turn drives the rotating plate 8, rotating rod 9, and lever 10 to rotate. The lever 10 causes the residual film to roll on the inner wall of the upper arc plate 4 and the lower arc mesh 5. After the residual film and debris roll to the position of the lower arc mesh 5, the debris is discharged through the mesh of the lower arc mesh 5 by means of centrifugal force and the weight of the debris itself, thus achieving impurity removal. When the residual film rolls, it moves from the feeding end of the upper arc plate 4 and the lower arc mesh 5 to the other end under the guidance of the spiral guide plate 6 and then discharges.
[0023] like Figure 2-4 As shown, it also includes partitions 11 respectively disposed inside the fixed plate 3 and opposite to each other, a feed guide cover 12 and a discharge guide cover 13 respectively fixed between the partition 11 and the adjacent fixed plate 3, and a spiral blade 14 disposed inside the rotating plate 8 and located in the feed guide cover 12 and the discharge guide cover 13 respectively; the upper arc plate 4, the lower arc mesh 5 and the spiral guide plate 6 are respectively fixed at both ends inside the partition 11, the partition 11 is provided with a clearance opening corresponding to the rotating plate 8, one end of the spiral blade 14 is fixed to the inner side of the rotating plate 8, and the other end extends into the upper arc plate 4 and the lower arc mesh 5, the spiral blade 14, the rotating rod 9, the lever 10 and the rotating shaft 7 are all located inside the feed guide cover 12 and the discharge guide cover 13, the spiral blade 14 is located outside the rotating rod 9, and the feed guide cover 12 and the discharge guide cover 13 are respectively provided with a feed port and a discharge port.
[0024] The partition 11 is used to fix the upper arc plate 4, the lower arc mesh 5 and the spiral guide plate 6, and forms a feeding and discharging space between the partition 11 and the fixed plate 3. The feeding guide cover 12 and the discharging guide cover 13 respectively cover the spiral blades 14, the rotating rod 9, the lever 10 and the rotating shaft 7 between the two partitions 11 and the fixed plate 3. Only the feeding guide cover 12 is equipped with spiral blades 14.
[0025] After the residual film enters the feed guide plate 12, it is pushed by the spiral blade 14 into the space between the upper arc plate 4 and the lower arc mesh 5 for impurity removal. After impurity removal, the residual film enters the discharge guide plate 13 and is discharged from the discharge port on one side of the discharge guide plate 13. This makes feeding and discharging more convenient and effectively avoids material accumulation.
[0026] like Figure 1 and Figure 5 As shown, it also includes a film crushing mechanism mounted on the mounting frame 1. The film crushing mechanism includes a housing 15, a fan blade 16 rotatably mounted inside the housing 15, a crushing motor 17 mounted inside the housing 15 and connected to the fan blade 16 in a transmission manner, and a crushing blade 18 fixed on one side of the fan blade 16. The crushing motor 17 drives the fan blade 16 to rotate and drives the crushing blade 18 to rotate synchronously. The upper end of the housing 15 is provided with a feed inlet, the lower end is provided with a discharge outlet and is connected to the feed inlet of the feed guide cover plate 12.
[0027] The crushing motor 17 drives the fan blades 16 to rotate, forming a suction force to facilitate the entry of residual film. When the residual film enters, the crushing blades 18 on the fan blades 16 cut the residual film and debris, making it easier for the debris to separate from the residual film during subsequent rolling.
[0028] like Figure 1 As shown, it also includes a protective plate 19 set on the mounting frame 1 and located in front of, behind and above the upper arc plate 4 and the lower arc mesh 5. The protective plate 19 and the fixing plate 3 together form a box structure with an opening at the lower end.
[0029] The protective plate 19 and the fixing plate 3 cover the upper arc plate 4 and the lower arc mesh 5, thus providing protection.
[0030] like Figure 1 As shown, it also includes a receiving hopper 20 disposed on the mounting frame 1 and located below the lower arc mesh 5, and an auger conveying mechanism disposed at the lower end of the receiving hopper 20, wherein the upper end of the auger conveying mechanism is connected to the lower end of the receiving hopper 20.
[0031] The receiving hopper 20 can collect debris falling from the lower arc net 5 and transport it to a fixed position under the action of the auger conveyor mechanism, which facilitates subsequent collection and transportation.
[0032] like Figure 1As shown, the auger conveying mechanism includes a conveying cylinder 21, an auger motor 22 disposed at one end of the conveying cylinder 21, an auger shaft 23 disposed inside the conveying cylinder 21, and auger blades disposed on the auger shaft 23 and located inside the conveying cylinder 21. The upper end of the conveying cylinder 21 is connected to the lower end of the receiving hopper 20. The auger motor 22 is drivenly connected to one end of the auger shaft 23. The auger blades rotate synchronously with the auger shaft 23.
[0033] The receiving hopper 20 has a triangular cross-section. Both the upper end of the conveying cylinder 21 and the lower end of the receiving hopper 20 are provided with connection openings. After the debris falls into the receiving hopper 20, it enters the conveying cylinder 21. Under the action of the auger blades, it is conveyed to one end of the conveying cylinder 21 and then falls to the ground, which is convenient for later collection and sorting.
