Description

Technical Field

[0001] The present application relates to the field of plastic films, and in particular, to a device for recycling farmland mulch films. Background Art

[0002] The current residual film recycling machine mainly recycles large pieces of residual film on the surface of the soil, while the smaller residual film in the tillage layer is difficult to recycle. The main component of ground film is polyvinyl chloride (PVC), which has great harm and is difficult to clean.

[0003] Unlike the dry sandy soil in the north, the soil in the south is very sticky and contains a lot of moisture, and the mulch film is often stuck to the soil. Therefore, the mulch film commonly used in the south cannot be recycled using the mulch film recycling technology in the north after use. It is not as simple as simply collecting and recycling the mulch film, but it must be turned up from the soil, separated, and then recycled. This is a complicated process that is generally difficult to achieve with a purely mechanical structure. Therefore, a technology to solve the problem of mulch film recovery in the south is needed to fill the gap in this field. Summary of the invention

[0057] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0058] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0059] Reference Figure 1-6 The farmland mulch film recycling equipment includes a frame 1, a roller cutter drum 2, a collection box 3, an electrostatic generator 4, an electrostatic absorber 5, and a rotating device; a gearbox is provided on the frame 1, and the power of the front tractor is transmitted to the rotary tiller input gearbox through the transmission shaft on the tractor, and then to the side gearbox, and finally to the roller cutter drum 2, so that the roller cutter drum 2 rotates. A rotating shaft 146 is provided on the output end of the gearbox, and the rotating shaft 146 is rotatably arranged in the frame 1. The roller cutter drum 2 is fixed on the rotating shaft 146 and partially extends out of the frame 1. The roller cutter drum 2 is provided with a plurality of rake teeth 7 that match the electrostatic absorber 5; a discharge port 8 is opened on one side of the frame 1, and the collection box 3 is installed on the frame 1 located on the side of the discharge port 8. The electrostatic generator 4 and the electrostatic absorber 5 are both existing technologies. The electrostatic absorber 5 can use a magnetic rod to generate a positive electrode. The specific operating principle can be referred to the patent application number 2017105107070, so it will not be repeated. The electrostatic generator 4 is arranged in the frame 1 and is located above the roller cutter drum 2, and is used to generate static electricity on the film on the roller cutter drum 2. There are at least two electrostatic absorbers 5, which are respectively located at the discharge port 8, and are used to adsorb the film that generates static electricity. The rotating device is arranged on the frame 1, and is used to drive the electrostatic absorber 5 to rotate counterclockwise, and throw the film on the electrostatic absorber 5 into the collection box 3. Through the clockwise rotation of the roller cutter drum 2, the rake teeth 7 hook up the film in the farmland and move along the roller cutter drum 2. When it moves to the bottom of the electrostatic generator 4, the electrostatic generator 4 works to generate negative charges on the film. As the roller cutter drum 2 rotates, the electrostatic absorber 5 will adsorb the film that generates negative charges and adsorb it onto the electrostatic absorber 5, and then the film is thrown into the collection box 3 for collection under the drive of the rotating device, thereby solving the problem of cleaning the film in the south.

[0060] The rake teeth 7 are provided with barbs 9. Through the effect of the barbs 9, it is convenient to hook the film out of the farmland.

[0061] A guide plate 10 is provided on one end of the discharge port 8 near the inner side of the frame 1; there are two guide plates 10, which are symmetrically arranged at both ends of the discharge port 8, and there is a gap between the two guide plates 10. It is convenient to introduce the film into the discharge port 8, and then facilitate the adsorption of the electrostatic absorber 5.

[0062] The rotating device includes a first fixed plate 11, a first motor 12, a worm 13, a rotating shaft 14, and a worm wheel 15; there are two first fixed plates 11, which are fixedly arranged at both ends of the frame 1, respectively; the first motor 12 is fixedly arranged on the first fixed plate 11, the worm 13 is fixedly arranged on the output end of the first motor 12, the rotating shaft 14 is rotatably arranged between the two fixed plates, the worm wheel 15 is fixedly arranged on the rotating shaft 14, and meshes with the worm 13, and the electrostatic absorbers 5 are evenly distributed on the rotating shaft 14. The worm 13 is driven to rotate by the first motor 12, the worm 13 drives the worm wheel 15 to rotate, and the rotation of the worm wheel 15 drives the rotating shaft 14 to rotate, thereby driving the electrostatic absorber 5 to rotate, so that the film on the electrostatic absorber 5 is thrown into the collection box 3.

[0063] In order to ensure that the film on the electrostatic absorber 5 can be thrown into the collection box 3 normally, the present application also includes a blocking device for picking up the film on the electrostatic absorber 5 and dropping it into the collection box 3. The blocking device includes a support rod 16, a first connecting plate 17, a second connecting plate 18, a blocking piece 19, and a first pin 20; the support rod 16 is fixed on the collection box 3, the first connecting plate 17 is fixed on the support rod 16, the second connecting plate 18 is arranged on the first connecting plate 17 through the first pin 20, the blocking piece 19 is fixed on the second connecting plate 18, and one end of the blocking piece 19 faces the side of the electrostatic absorber 5, and the gap between the blocking piece 19 and the electrostatic absorber 5 is less than the thickness of the film. The first pin 20 is threadedly connected to the first connecting plate 17. Under the action of the baffle 19, when the electrostatic absorber 5 adsorbs the film on the electrostatic absorber 5, and the electrostatic absorber 5 is rotating, the baffle 19 will block the film on the electrostatic absorber 5. Since the electrostatic absorber 5 is rotating, the film is blocked by the baffle 19 and falls into the collection box 3, so that too much film is wrapped around the electrostatic absorber 5, which causes the electrostatic absorber 5 to be unable to adsorb the film with negative charge. Under the action of the first pin 20, it is convenient to install the second connecting plate 18 and adjust the angle of the second connecting plate 18.

[0064] The side of the blocking piece 19 facing the electrostatic absorber 5 is configured as an inclined portion 21 . This further facilitates blocking the film, and the film can be guided into the collection box 3 under the action of the inclined portion 21 .

[0065] The collection box 3 is provided with a filter plate 22, and a plurality of filter holes 23 are provided on the filter plate. Since the film is hooked out from the farmland, the film is covered with soil, and the soil can fall back into the farmland from the filter holes 23. Specifically, in order to avoid clogging of the filter holes 23, the present application provides a slot body 24 at both ends of the collection box 3, and both ends of the filter plate 22 extend into the slot body 24 and flexibly cooperate with the slot body 24. A second fixing plate 25 is provided on the outer wall of the collection box 3, and a second motor 26 is installed on the second fixing plate 25. A connecting shaft 27 is provided on the output end of the second motor 26, and one end of the connecting shaft 27 rotates and extends into the slot body 24. A protrusion 28 is provided on the connecting shaft 27, and one end of the protrusion 28 abuts against the filter plate 22. A vibration spring 29 is installed between the filter plate 22 and the inner wall of the slot body 24.

[0066] A plurality of accommodating cavities 30 are provided on the roller cutter cylinder 2, and the rake teeth 7 are movably arranged on the accommodating cavities 30. A driving device for driving the rake teeth 7 to move is installed in the accommodating cavities 30. When the rake teeth 7 hit a harder object such as a stone, the rake teeth 7 can be driven to move into the accommodating cavities 30, thereby reducing damage to the rake teeth 7. Specifically, the driving device includes a driving member 31, a first connecting block 32, a second connecting block 33, a connecting rod 34, a pressure sensor 35, and a second pin 36; the driving member 31 is fixedly arranged on the inner wall of the accommodating chamber 30, and the driving member 31 can adopt a hydraulic push rod, a pneumatic telescopic rod, an electric telescopic rod, etc. The first connecting block 32 is fixedly arranged on the driving member 31, and the second connecting block 33 is hingedly connected to the first connecting block 32 through the second pin 36. The connecting rod 34 is fixedly arranged on one end of the second connecting block 33. The pressure sensor 35 is arranged on the accommodating chamber 30 and is located on one side of the connecting rod 34. The pressure sensor 35 is electrically connected to the driving member 31, so that the pressure sensor 35 controls the opening and closing of the driving member 31, and the rake teeth 7 are installed on the second connecting block 33. When the rake teeth 7 hit a harder object such as a stone, the roller cutter 2 drives the rake teeth 7 to rotate, which will cause the rake teeth 7 to move backward, and through the hinge of the second connecting block 33 and the first connecting block 32, the connecting rod 34 on the second connecting block 33 will contact the pressure sensor 35, and after a certain period of contact, it will continue to squeeze the switch of the pressure sensor 35, so that the pressure sensor 35 controls the opening of the driving member 31, thereby extending and retracting the first connecting block 32, so that the first connecting block 32 moves into the accommodating chamber 30, the first connecting block 32 drives the movement of the second connecting block 33, and the second connecting block 33 drives the rake teeth 7 to move into the accommodating chamber 30, thereby avoiding the collision of the rake teeth 7 with harder objects such as stones and causing damage to the rake teeth 7. At the same time, in order to prevent the rake teeth 7 from shrinking into the accommodating chamber 30 due to inertia and other factors during rotation, the present application sets the rotational force / hinge force between the second pin 36 and the first connecting block 32 to be relatively tight. General contact (such as the rake teeth 7 touching a film or plastic, or the rake teeth 7 moving backwards due to the inertia of the rotation of the roller cutter 2, etc.) will not drive the second connecting block 33 to move relative to the first connecting block 32. Only after a long period of continuous collision with a harder object such as a stone can the second connecting block 33 be driven to move relative to the first connecting block 32, thereby allowing the rake teeth 7 to move into the accommodating chamber 30.
