Description

Technical Field

[0001] This utility model relates to the field of waste recycling technology, specifically to a machine for recycling residual agricultural film. Background Technology

[0002] Mulching technology is an advanced agricultural planting technique that improves and optimizes the crop growth environment, overcomes adverse conditions, and achieves early maturity, high yield, high quality, and high efficiency. my country has been using mulching technology for over 30 years, consistently ranking first in the world in terms of coverage area and usage. While mulching effectively increases crop yields, it also presents the problem of mulch residue. Due to its difficulty in degradation, large amounts of mulch remain in the soil after harvest, causing pollution and damage. Therefore, agricultural mulch residue recycling machines are needed to collect and recycle it.

[0003] Most existing farmland residual plastic film recycling machines use rollers with film-pulling plates to rotate and recycle the plastic film. However, this pushes soil particles into the plastic film and collection box, resulting in a large amount of soil particles in the collected plastic film, which reduces the quality of plastic film recycling. Some existing recycling machines also use fans to collect the film, but this simple adsorption cannot recycle the plastic film pressed into the soil, and the recycling effect is not ideal. Furthermore, soil particles are still sucked in. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a farmland residual plastic film recycling machine. It solves the problem that most recycling machines use rollers with film-pulling plates to rotate and recycle plastic film. However, this method pushes soil particles into the plastic film and collection box, resulting in a large amount of soil particles in the collected plastic film, which reduces the quality of plastic film recycling. In addition, some existing recycling machines use fans to collect the film, but this simple adsorption cannot recycle the plastic film pressed into the soil, and the recycling effect is not ideal. Furthermore, there is still the problem that soil particles are sucked in.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a farmland residual plastic film recycling machine, comprising a machine body, an absorption box fixedly connected to one side of the top of the machine body, an absorption port fixedly connected to the bottom of the absorption box penetrating the top wall of the machine body, a collection box fixedly connected to the other side of the top of the machine body, a connecting pipe fixedly connected between one side of the absorption box and one side of the collection box, a film-removing mechanism provided inside the absorption port, an air-blowing mechanism provided on the surface of the machine body, a negative pressure fan fixedly connected to one side of the top of the machine body, an air suction pipe connected to the output end of the negative pressure fan, one end of the air suction pipe penetrating the top wall of the absorption box and extending into the interior of the absorption box, and a film-removing mechanism provided inside the collection box. The device includes a filter plate, a controller fixedly connected to one side of the collection box, a discharge pipe fixedly connected to one side of the collection box, an electromagnetic valve fixedly installed inside the discharge pipe, and a ash discharge pipe fixedly connected to the bottom of the collection box. The filter plate filters out fine soil particles from the surface of the mulch film entering the collection box. The filtered mulch film can be discharged through the discharge pipe by opening the electromagnetic valve via the controller. The filtered fine soil particles slide down the inclined plate in the collection box to one side of the ash discharge pipe and are finally discharged through the ash discharge pipe. Furthermore, the air blowing mechanism allows the mulch film to pass normally through the channels inside the absorption box. Therefore, this device can remove soil particles mixed in with the recycled mulch film, improving the quality of mulch film recycling.

[0008] Preferably, elastic sheets are fixedly connected to both sides of the inside of the absorption box, and a filter cover is fixedly connected to the top wall of the inside of the absorption box. The filter cover is fitted onto one end of the suction pipe, and an observation window is fixedly connected to the front of the collection box. The elastic sheets can beat and block some soil particles sucked into the absorption box, prioritizing the removal of relatively large soil particles, thus improving the cleanliness of the mulch film recycling. The filter cover can prevent the mulch film from being sucked into the suction pipe and clogging it. The observation window allows for real-time observation of the mulch film collection and filtration status inside the collection box.

[0009] Preferably, the inner surface of the absorption box and the inner surface of the connecting pipe are located on the same inclined plane, and the end of the connecting pipe near the collection box is lower than the end near the absorption box. Through the inclined plane and the inclined connecting pipe, the mulch film can be easily entered into the collection box for collection.

[0010] Preferably, the inside of the collection box has an inclined surface, and a vibration motor is fixedly connected to the top side of the inclined surface. The output end of the vibration motor abuts against the bottom of the filter plate. Slider blocks are fixedly connected to both sides of the filter plate. Slide grooves are formed on both sides of the inside of the collection box. The sliders are slidably connected to the inside of the slide grooves. A spring is elastically connected between the bottom of the slider and the inner wall of the slide groove. The inclined surface allows the filtered soil particles to slide to one side of the ash discharge pipe due to gravity and be discharged through the ash discharge pipe. The output end of the vibration motor touches the bottom of the filter plate and causes it to vibrate. The vibrating filter plate can filter soil particles more effectively. When the filter plate vibrates, the slider moves up and down inside the slide groove, and the spring continuously extends and retracts, reducing the wear of the filter plate caused by vibration.

[0011] Preferably, the film-taking mechanism includes a power unit, which is fixedly installed on the front of the absorption port. A roller is fixedly connected to the output end of the power unit, and the roller is rotatably connected to the inside of the absorption port. A film-taking plate is fixedly connected to the surface of the roller.

[0012] Preferably, the film-taking mechanism further includes a film-dispensing plate, which is fixedly connected to the inside side of the absorption port. The surface of the film-dispensing plate is provided with a film-dispensing groove, which is adapted to the shape of the film-taking plate. The film-taking mechanism can pick up the film that is not easy to be absorbed while adsorbing the film, so that the subsequent negative pressure fan and air blowing mechanism can guide it into the collection box.

[0013] Preferably, the blowing mechanism includes an air pump, which is fixedly connected to the top of the machine body. The output end of the air pump passes through the top wall of the machine body and is connected to an air blowing pipe. One end of the air blowing pipe is connected to a through pipe, and a jet nozzle is connected to the top side of the through pipe. The end of the jet nozzle faces the inside of the absorption port. A support rod is fixedly connected to the air blowing pipe and the machine body. The blowing mechanism can blow the mulch film scraped off the film stripping plate into the inside of the absorption box, preventing the mulch film on the film stripping plate from falling onto the farmland surface, thus improving the mulch film recycling rate. Furthermore, the blowing mechanism can form an airflow inside the absorption box, helping the mulch film to quickly enter the inside of the absorption box for collection, thereby improving the mulch film recycling efficiency.

[0014] (III) Beneficial Effects

[0015] This utility model provides a machine for recycling residual agricultural film. It has the following beneficial effects:

[0016] (I) This farmland residual mulch film recycling machine, through the overall setup of the film taking mechanism, absorption box, elastic sheet, negative pressure fan and filter plate, can reduce the risk of the device collecting large soil particles through negative pressure adsorption, and the elastic sheet can beat and block most of the small soil particles, which can reduce the soil particles being recycled together with the mulch film. At the same time, the filter plate can remove the soil particles mixed in with the recycled mulch film, which improves the cleanliness of the mulch film recycling and improves the quality of mulch film recycling.

[0017] (ii) The agricultural residual plastic film recycling machine, through the setting of the air blowing mechanism, can blow the plastic film that has been picked up and scraped off into the inside of the absorption box, preventing the plastic film on the film-removing plate from falling onto the surface of the farmland, thereby improving the recycling rate of plastic film. In addition, the air blowing mechanism can form an airflow inside the absorption box, which helps the plastic film to quickly enter the top side of the absorption box and finally enter the collection box for collection, thereby improving the recycling efficiency of plastic film.

[0018] (III) The farmland residual mulch film recycling machine, through the setting of a vibrating motor, slider and spring, etc., the vibrating motor can quickly vibrate the filter plate, thereby facilitating the filter plate to filter out soil particles and improving the filtration efficiency. In addition, when the filter plate vibrates, the slider moves up and down inside the slide groove, and the spring continuously extends and retracts. The setting of the spring can prevent the vibration from damaging the filter plate and extend the service life of the device. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] See Figure 1-5This utility model provides a technical solution: a farmland residual plastic film recycling machine, the structure of which includes a body 1, an absorption box 2 fixedly connected to one side of the top of the body 1, an absorption port 3 fixedly connected to the bottom of the absorption box 2 through the top wall of the body 1, a collection box 4 fixedly connected to the other side of the top of the body 1, a connecting pipe 5 fixedly connected between one side of the absorption box 2 and one side of the collection box 4, a film-removing mechanism 6 provided inside the absorption port 3, an air blowing mechanism 7 provided on the surface of the body 1, and a negative pressure air blower fixedly connected to one side of the top of the body 1. Machine 8, the output end of the negative pressure fan 8 is connected to a suction pipe 9. One end of the suction pipe 9 passes through the top wall of the absorption box 2 and extends into the interior of the absorption box 2. A filter plate 10 is installed inside the collection box 4. A controller 11 is fixedly connected to one side of the front of the collection box 4. A discharge pipe 12 is fixedly connected to one side of the collection box 4. A solenoid valve 21 is fixedly installed inside the discharge pipe 12. A ash discharge pipe 13 is fixedly connected to the bottom of the collection box 4. The film taking mechanism 6, the air blowing mechanism 7 and the negative pressure fan 8 are started synchronously by the controller 11. The operator drives the machine 1 to the area where the plastic film needs to be recycled. The film-picking mechanism 6 lifts up the residual plastic film from the farmland surface. Then, under the action of the air-blowing mechanism 7, the lifted plastic film enters the absorption box 2. The negative pressure fan 8 draws air through the suction pipe 9, creating a negative pressure environment inside the absorption box 2. The plastic film then enters the collection box 4 through the connecting pipe 5. The filter plate 10 filters out fine soil particles from the surface of the plastic film entering the collection box 4. The filtered plastic film can then be processed by the controller 11. The solenoid valve 21 is opened and discharged from the discharge pipe 12. The filtered fine soil particles slide down the inclined plate in the collection box 4 to one side of the ash discharge pipe 13. Finally, the soil particles are discharged through the ash discharge pipe 13. The elastic sheet 14 can beat and block some of the soil particles sucked into the absorption box 2, and remove the relatively large soil particles first. In addition, due to the setting of the air blowing mechanism 7, the mulch film can pass normally through the channel in the absorption box 2. Thus, the device can remove the soil particles mixed in the recycled mulch film and improve the quality of mulch film recycling.

[0027] The absorption box 2 has elastic sheets 14 fixedly connected to both sides inside, and a filter cover 15 fixedly connected to the top wall inside. The filter cover 15 is fitted onto one end of the suction pipe 9. The collection box 4 has an observation window 16 fixedly connected to the front. The elastic sheets 14 can beat and block some soil particles sucked into the absorption box 2, and prioritize the removal of relatively large soil particles, thus improving the cleanliness of the mulch film recycling. The filter cover 15 can prevent the mulch film from being sucked into the suction pipe 9 and clogging the suction pipe 9. The observation window 16 can be used to observe the collection and filtration status of the mulch film inside the collection box 4 in real time.

[0028] The inner surface of the absorption box 2 and the inner surface of the connecting pipe 5 are located on the same inclined plane, and the end of the connecting pipe 5 near the collection box 4 is lower than the end near the absorption box 2. Through the inclined plane and the inclined connecting pipe 5, the mulch film can be easily entered into the collection box 4 for collection.

[0029] The collection box 4 has an inclined surface inside, and a vibration motor 17 is fixedly connected to the top side of the inclined surface. The output end of the vibration motor 17 rests against the bottom of the filter plate 10. Slider blocks 18 are fixedly connected to both sides of the filter plate 10. The collection box 4 has grooves 19 on both sides inside, and the sliders 18 are slidably connected inside the grooves 19. A spring 20 is elastically connected between the bottom of the slider 18 and the inner wall of the groove 19. The inclined surface allows the filtered soil particles to slide towards one side of the ash discharge pipe 13 due to gravity. Finally, the soil particles are discharged from the collection box 4 through the ash discharge pipe 13. The output end of the vibration motor 17 touches the bottom of the filter plate 10 and causes it to vibrate. The vibrating filter plate 10 can filter soil particles better. When the filter plate 10 vibrates, the slider 18 moves up and down inside the groove 19, and the spring 20 continuously extends and retracts, reducing the wear of the filter plate 10 caused by vibration.

[0030] The film-taking mechanism 6 includes a power unit 61, which is fixedly installed on the front of the absorption port 3. The output end of the power unit 61 is fixedly connected to a roller 62, which is rotatably connected to the inside of the absorption port 3. A film-taking plate 63 is fixedly connected to the surface of the roller 62.

[0031] The film-taking mechanism 6 also includes a film-removing plate 64, which is fixedly connected to one side of the inside of the absorption port 3. The surface of the film-removing plate 64 is provided with a film-removing groove 65, which is adapted to the shape of the film-taking plate 63. The power unit 61 is started by the controller 11 to work. The power unit 61 drives the roller 62 to rotate, and the roller 62 drives the film-taking plate 63 to rotate. The rotation of the film-taking plate 63 can lift the film on the surface of the farmland until the film-taking plate 63 rotates to one side of the film-removing plate 64 and scrapes the film off using the film-removing groove 65. The scraped film is located on the top of the film-removing plate 64 and is then blown into the inside of the absorption box 2 by the air blowing mechanism 7.

[0032] The blowing mechanism 7 includes an air pump 71, which is fixedly connected to the top of the body 1. The output end of the air pump 71 passes through the top wall of the body 1 and is connected to an air blowing pipe 72. One end of the air blowing pipe 72 is connected to a through pipe 73. A jet nozzle 74 is connected to the top side of the through pipe 73. The end of the jet nozzle 74 faces the inside of the absorption port 3. A support rod 75 is fixedly connected between the air blowing pipe 72 and the body 1. The air blown out by the air pump 71 enters the inside of the through pipe 73 through the air blowing pipe 72 and is finally blown into the inside of the absorption port 3 through the jet nozzle 74. By blowing air into the inside of the absorption port 3, the blown air can push the plastic film scraped off the membrane plate 64 into the inside of the absorption box 2.

[0033] During operation, when collecting residual plastic film from the farmland surface, the controller 11 activates the film-collecting mechanism 6, the air-blowing mechanism 7, and the negative pressure fan 8 simultaneously. The operator drives the machine 1 to the area where plastic film collection is needed. The film-collecting mechanism 6 lifts up the residual plastic film from the farmland surface. Then, under the action of the air-blowing mechanism 7, the lifted plastic film enters the absorption box 2. The negative pressure fan 8 draws air through the suction pipe 9, creating a negative pressure environment inside the absorption box 2. The plastic film then enters the collection box 4 through the connecting pipe 5. The filter plate 10 filters the surface of the plastic film entering the collection box 4. The fine soil particles on the surface are filtered. The filtered mulch film can be discharged from the discharge pipe 12 by opening the solenoid valve 21 through the controller 11. The filtered fine soil particles slide down to one side of the ash discharge pipe 13 through the inclined plate in the collection box 4. Finally, the soil particles are discharged through the ash discharge pipe 13. The elastic sheet 14 can beat and block some of the soil particles sucked into the absorption box 2, and prioritize the removal of relatively large soil particles. In addition, due to the setting of the air blowing mechanism 7, the mulch film can pass normally through the channel in the absorption box 2. Thus, the device can remove the soil particles mixed in with the recycled mulch film, thereby improving the quality of mulch film recycling.

[0034] When the filter plate 10 filters the collected mulch film, the controller 11 controls the vibration motor 17 to work. The output end of the vibration motor 17 touches the bottom of the filter plate 10 and causes it to vibrate. The vibrating filter plate 10 can filter soil particles better. When the filter plate 10 vibrates, the slider 18 moves up and down inside the slide groove 19, and the spring 20 continuously extends and retracts. The spring 20 can prevent the vibration from damaging the filter plate 10 and extend the service life of the device.

[0035] When the film-taking mechanism 6 is working, the power unit 61 is started by the controller 11. The power unit 61 drives the roller 62 to rotate, and the roller 62 drives the film-taking plate 63 to rotate. The rotation of the film-taking plate 63 can lift the film on the surface of the farmland until the film-taking plate 63 rotates to one side of the film-removing plate 64 and uses the film-removing groove 65 to scrape the film off. The scraped film is located at the top of the film-removing plate 64, and then it is blown into the interior of the absorption box 2 under the action of the air blowing mechanism 7.

[0036] When the air blowing mechanism 7 is working, the air pump 71 is started by the controller 11. The air blown by the air pump 71 enters the interior of the through pipe 73 through the air blowing pipe 72, and finally blows into the interior of the absorption port 3 through the air jet head 74. By blowing air into the interior of the absorption port 3, the blown air can blow the mulch film scraped off the film plate 64 into the interior of the absorption box 2. The air blowing mechanism 7 can blow the mulch film scraped off the film plate 64 into the interior of the absorption box 2, preventing the mulch film on the film plate 64 from falling onto the farmland surface, thus improving the mulch film recycling rate. In addition, the air blowing mechanism 7 can form an airflow inside the absorption box 2, which helps the mulch film to quickly enter the interior of the absorption box 2 for collection, thus improving the mulch film recycling efficiency.
