[0020] This utility model addresses the shortcomings of existing technologies by providing a residual film recycling vehicle towed by agricultural machinery. This vehicle can effectively recover residual film from the surface and shallow layers of the ground, reducing land pollution, improving the ecological environment, increasing crop yields, and promoting resource recycling. Furthermore, it can save significant time and manpower and improve crop planting efficiency. The recycling vehicle has a simple structure, reliable operation, is not prone to damage, and is economical and practical, reducing farmers' purchase and maintenance costs.
[0021] See Figures 1-4 The utility model mainly includes a frame 1, a support wheel 2, a sprocket assembly shield 3, a film-removing plowshare 4, a gearbox 5, a traction mechanism 6, a drive shaft 7, a bearing 8, an output shaft 9, a film-removing chain 10, a crossbar 11, a film-removing claw 12, a film-collecting box 13, a driven sprocket 14, a driving sprocket 15, a guide wheel 16, a driving sprocket 17, a U-shaped plate 18 and a fixing bolt 19. Among them, the drive shaft 7, two film-removing chains 10, multiple crossbars 11, a film-collecting box 13, a driving sprocket 17, a support wheel 2, a guide wheel 16, a film-removing claw 12, a U-shaped plate 18 and a fixing bolt 19 constitute a residual film recovery mechanism, and the gearbox 5, the driving sprocket 15 and the driven sprocket 14 constitute a driving mechanism.
[0022] Travel wheels are installed at the bottom of the frame 1, and a film-removing plowshare 4 is installed at the bottom front of the frame 1 to loosen the soil and float the residual film to the surface for easy collection. The gearbox 5 and the traction mechanism 6 are installed at the front of the frame 1. The frame 1 is connected to the agricultural tractor through the traction mechanism 6 and can be towed by the agricultural tractor. The input shaft of the gearbox 5 is connected to the rear output shaft of the agricultural tractor through a cross universal joint. The agricultural tractor serves as a power source for residual film recovery, and its torque is transmitted to the single-input, dual-output gearbox 5 through the cross universal joint. An output shaft 9 is connected to each side of the gearbox 5, and the torque is transmitted through the output shaft 9 to drive the sprocket in the sprocket assembly shield 3 to rotate; the end of the output shaft 9 away from the gearbox 5 is rotatably connected to the frame 1 through a bearing 8 and is equipped with a driving sprocket 15, and the driving shaft 7 is located behind the film plow 4; the two ends of the driving shaft 7 are rotatably connected to the two sides of the frame 1 through bearings, and the two driven sprockets 14 are respectively fixed to the two ends of the driving shaft 7 and are respectively connected to the driving sprockets 15 at the ends of the two output shafts 9 through a transmission chain. The two driving sprockets 17 are also respectively fixed at At both ends of the drive shaft 7, the active sprocket 15 drives the driven sprocket 14 to rotate through the transmission chain; the film collecting box 13 is fixed to the upper rear end of the frame 1, and the top of the film collecting box 13 is open. Support wheels 2 and guide wheels 16 are installed at the upper ends and front ends of the two side walls of the film collecting box 13. The two film-forming chains 10 are respectively located on both sides of the frame 1, and the inner side of each annular film-forming chain 10 is engaged with the corresponding drive sprocket 17 and support wheel 2. The guide wheel 16 is pressed against the outer side of the film-forming chain 10, so that the film-forming chain 10 runs along the upper edge and front edge of the side wall of the film-forming box 13. When the driving sprocket 17 rotates, it drives the film lifting chain 10 to rotate; multiple cross bars 11 are arranged at equal intervals along the film lifting chains 10, and the two ends of each cross bar 11 are fixedly connected to the two film lifting chains 10. A plurality of film lifting claws 12 are installed on the cross bars 11 along the length direction of the cross bars 11. When the film lifting chains 10 rotate, they drive the cross bars 11 and the film lifting claws 12 to rotate together. When the film lifting claws 12 rotate to the bottom of the frame 1, they rub against the soil, pick up the residual film on the surface and in the shallow layer, and transmit it; when the film lifting claws 12 carrying the residual film move to the top and rear of the film collecting box 13, they rotate from the top of the film lifting chain 10 to the bottom of the film lifting chain 10. Due to the bumpy vibration of the film lifting claws 12, the residual film falls into the film collecting box 13, achieving efficient recovery of the residual film. The guide wheel 16 is a rubber-coated roller, that is, a ring-shaped rubber sleeve is set on its rim.
[0023] See Figure 3 、 Figure 4The film-lifting claw 12 is connected to the cross bar 11 through a U-shaped plate 18 and a fixing bolt 19. The film-lifting claw 12 is made of steel wire. The middle part of the steel wire is a coil spring bent into two sections with opposite rotation directions. The two sections of coil spring are sleeved on the outside of the cross bar 11. The U-shaped plate 18 is sleeved on the connecting part of the two sections of coil spring. The fixing bolt 19 passes through the through holes at both ends of the U-shaped plate 18 and the radial through holes on the cross bar 11 and is screwed into the nut. The two ends of the steel wire are parallel to each other and perpendicular to the cross bar 11. When the cross bar 11 rotates to the lowest point with the film-lifting chain 10, the two ends of the steel wire rotate to the bottom of the cross bar 11 and rub against the ground surface, so that the residual film on the ground can be scraped off. When there are hard obstacles such as stones on the ground, the end of the steel wire hits the obstacle and rotates around the cross bar 11. After leaving the obstacle, it relies on the elastic force of the coil spring to reset. The coil spring plays a buffering role to prevent the film-lifting claw 12 from being permanently deformed and damaged.
[0024] This utility model uses an agricultural tractor as its power source and uses film scraping claws to scrape away residual film adhering to the ground. It is highly efficient and reliable, operating even in harsh environments. Compared to traditional residual film recycling vehicles, this utility model has the advantages of simple structure, low cost, and ease of use, reducing the purchase and maintenance costs for farmers.
