1. A hard stubble land air-suction type residual film recycling machine comprises a traction frame, a frame beam, a front land wheel, a stubble leveling and film removing device, a soil crushing and pressing device, a soil-film separating device, a rear land wheel and a profiling machine frame;

  • a stubble leveling and film forming device, a soil crushing and pressing device, a soil film separating device and a rear land wheel are sequentially arranged behind the front land wheel;

    the method is characterized in that;

    the plastic film mulching machine further comprises an auger conveying device (8) and a film collecting device, wherein the auger conveying device is arranged behind the soil film separating device (6), the film collecting device is positioned above the soil film separating device (6), and the auger conveying device is connected with the film collecting device through a film discharging barrel (11);

    the auger conveying device comprises an auger shaft (116), an auger groove (111) and an auger propeller (110), the auger propeller (110) is arranged on the auger shaft (116), and an auger belt pulley (106) and a fan driving wheel (113) are respectively arranged at two ends of the auger shaft (116);

    a fan belt pulley (114) is connected below the fan driving wheel (113), the fan belt pulley (114) is connected with a fan (115), a fan discharge port (112) is arranged above the fan (115), and the fan discharge port (112) is connected with the film discharging barrel (11);

    the auger belt pulley (106) is connected with a power device;

    the power device comprises a gearbox (101), a transverse transmission shaft (103), a lower belt pulley (104), a transmission belt (105), a speed-increasing belt pulley (107) and a transmission wheel (109);

    the gearbox (101) is connected with the transverse transmission shaft (103), the transverse transmission shaft (103) is connected with the lower belt pulley (104), a transmission belt (105) is arranged between the lower belt pulley (104) and the speed-increasing belt pulley (107), the speed-increasing belt pulley (107) is coaxially connected with a transmission wheel (109), and the transmission wheel (109) is in transmission connection with the auger belt pulley (106);

    sieve pores are arranged at the bottom of the auger groove (111);

    the soil-film mixture with larger mass enters an auger conveying device for soil-film separation, the crushed soil falls down from a sieve pore at the bottom of an auger groove (111), and the residual film is conveyed by the auger and enters a film outlet cylinder (11) from a fan discharge port (112).
