Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural environmental protection machinery technology, specifically to a residual film spreading and soil and debris separation device. Background Technology
[0002] Currently, most agricultural film recycling machinery uses a pick-up and packing method. The recycled film bales are roughly cylindrical in shape, containing a large amount of cotton stalks, cotton, and soil debris. The long strips of film easily entangle with the stalks, resulting in a mixture with low density, large gaps, low hardness, and a high content of tough materials. Post-recycling processing of agricultural film first involves mechanical crushing and unpacking pre-treatment. Then, using equipment such as wind sorting, vibration sorting, and water washing separation, the cotton stalks, cotton, and soil debris are separated from the film. The clean film can then be used to manufacture plastic pellets, achieving resource utilization.
[0003] The mechanical crushing and unpacking pretreatment of residual film packages often uses a shredder. Since the mulch film is made of plastic, the residual film mixture is broken into blocks by the shredder, and the boundaries of the residual film are stuck together and not easy to break. The residual film is wrapped with cotton stalks, soil and other debris, which makes it difficult to separate the cotton stalks, cotton and soil and other debris in the subsequent sorting.

[0017] Furthermore, it also includes a film outlet device, which is disposed on the rear side of the frame. The film outlet device includes a film outlet hood, a film outlet pipe, a film outlet fan, and a film discharge pipe.
[0018] The film outlet hood is connected to the air outlet on the rear side of the soil removal protective cover, the two ends of the film outlet pipe are connected between the air inlet of the film outlet fan and the film outlet hood, and the film discharge pipe is connected to the air outlet of the film outlet fan.

The second separating screen 230 is connected to the side wall of the scattering frame 210 and is located below the spiked roller 220. When the spiked roller 220 rotates, it scatters the residual film mixture on the second separating screen 230 through the spikes on it. At the same time, some cotton stalks and soil debris are discharged through the second separating screen 230, and the remaining residual film mixture enters the soil removal device 300.
[0038] The above technical solution enables the scattering and separation of soil and impurities from the residual film mixture, improving the cleanliness of the separated impurities and further enhancing the efficiency of residual film resource utilization.
[0039] In this embodiment, the soil removal device 300 includes a first drive assembly 350, which is connected to a spiral shaft 320 to drive the spiral shaft 320 to rotate. Specifically, a spiral shaft 320 pulley is installed at one end of the spiral shaft 320. The first drive assembly 350 includes a spiral shaft 320 drive motor, which is mounted on the frame 100.

[0040] In this embodiment, the spreading device 200 includes a second drive assembly 240, which is connected to the spiked roller 220 to drive the spiked roller 220 to rotate.

Each set of paddle plates 330 includes multiple paddle plates 330 evenly arranged along the circumference of the spiral shaft 320. When the spiral shaft 320 rotates, the multiple sets of paddle plates 330 quickly beat the residual film mixture, causing the residual film, cotton stalks, and soil impurities in the residual film mixture to be separated and screened by the first separation screen 340.
[0043] As a preferred embodiment, the second separating screen 230 is provided with a concave arc portion 231, the shape of which is adapted to the rotation trajectory of the magnetic nails on the spike roller 220. When the spike roller 220 rotates, the spikes on the outer surface of the cylinder scatter the fed residual film mixture. At the same time, some cotton stalks and soil debris are discharged from the equipment through the second separating screen 230, and the remaining residual film mixture enters the soil removal device 300.
[0044] The residual film scattering and soil separation device provided in this embodiment also includes a soil removal device 400 located below the soil removal device 300. The soil removal device 400 includes a soil removal spiral shaft 410, a soil removal channel 420, and a soil removal slide plate 430.
[0045] The two ends of the discharge spiral shaft 410 are rotatably connected to the side plate of the frame 100. The discharge channel 420 is located below the discharge spiral shaft 410. The two sides of the discharge channel 420 are respectively connected to the discharge slide plate 430, which is used to guide the cotton stalks and soil debris passing through the first separation screen 340 into the discharge channel 420.
[0046] In addition, the impurity removal device 400 also includes a third drive device 440, which includes an impurity removal screw drive motor. An impurity removal screw motor sprocket is installed at the end of the output shaft of the impurity removal screw drive motor. An impurity removal screw shaft 410 sprocket is installed at the end of the impurity removal screw shaft 410. The impurity removal screw motor sprocket and the impurity removal screw shaft 410 sprocket transmit torque through a chain, so that the impurity removal screw drive motor drives the impurity removal screw shaft 410 to rotate. An impurity removal port is provided on the lower part of one side of the impurity removal screw shaft 410 channel. The cotton stalks and soil impurities are discharged from the equipment by rotating the impurity removal screw shaft 410.
[0047] The residual film scattering and soil separation device provided in this embodiment also includes a film discharge device 500, which is located on the rear side of the frame 100. The film discharge device 500 includes a film discharge hood 510, a film discharge pipe 520, a film discharge fan 530, and a film discharge pipe 540.
[0048] The membrane discharge hood 510 is connected to the air outlet on the rear side of the soil removal protective cover 310. The two ends of the membrane discharge pipe 520 are connected between the air inlet of the membrane discharge fan 530 and the membrane discharge hood 510. The membrane discharge pipe 540 is connected to the air outlet of the membrane discharge fan 530.
[0049] In addition, the film discharging device 500 also includes a fourth drive device 550, which includes a film discharging drive motor. A pulley for the film discharging fan 530 is installed at the shaft end of the film discharging fan 530. A pulley for the film discharging fan 530 motor is installed at the output shaft end of the film discharging drive motor. The pulley for the film discharging fan 530 and the pulley for the film discharging fan 530 motor are connected by a V-belt to transmit power, so that the film discharging drive motor drives the film discharging fan 530 to rotate.
[0050] As a preferred implementation, the positions of the film discharge hood 510 and the soil removal protective hood 310 are arranged correspondingly. Since both the soil removal device 300 and the debris removal device 400 are sealed structures, the inlet corresponding to the scattering device 200 is the air inlet of the film discharge fan 530. The function of the film discharge fan 530 is to attract residual film through the soil removal device 300 into the film discharge pipe 520 and then into the film discharge fan 530, and finally discharge it from the film discharge port.
[0051] The residual film spreading and soil separation device provided in this embodiment also includes a feeding device 600 disposed in front of the spreading device 200. The feeding device 600 includes a feeding conveyor belt assembly 610, a conveyor belt motor 620, a conveyor belt baffle 630 and a feeding frame 640.

The conveyor belt motor 620 is connected to the feeding conveyor belt assembly 610 and is used to drive the feeding conveyor belt to rotate.
[0053] The working principle of the residual film spreading and soil-debris separation device provided in this embodiment is explained below:
[0054] The residual film mixture, shredded by the shredder, enters the spreading device 200 via the feeding device 600 and the feeding conveyor belt assembly 610. When the spiked roller 220 in the spreading device 200 rotates, the spikes on the outer surface of the cylinder spread the residual film mixture. Simultaneously, some cotton stalks and soil debris are discharged from the equipment through the second separating screen 230, while the remaining residual film mixture enters the soil removal device 300. The function of the film discharge fan 530 is to attract the residual film into the spiral shaft 320 of the soil removal device 300. When the spiral shaft 320 rotates, multiple sets of baffles 330 rapidly beat the residual film mixture, separating the residual film, cotton stalks, and soil debris. The mixture is then guided through the second separating screen 230 and the waste removal slide plate 430 into the waste removal channel 420. The rotation of the waste removal spiral shaft 410 causes the cotton stalks and soil debris to be discharged from the equipment. The function of the film discharge fan 530 is to attract the residual film through the soil removal device 300 into the film discharge pipe 520, and then into the film discharge fan 530, finally discharging it to the outside through the film discharge pipe 540.
[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
