Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of plastic recycling equipment, and specifically relates to an air separator for agricultural film. Background Technology
[0002] With the increasing use of agricultural film, pollution problems have become increasingly serious. Large amounts of discarded agricultural film are indiscriminately disposed of, not only damaging the natural landscape and affecting rural environmental sanitation, but also wasting resources, especially causing serious pollution to the soil environment. Harmful substances (dioxins) produced by the film at high temperatures dissolve directly into the soil, causing serious soil pollution. Agricultural products produced from this film are harmful to human health, and the released toxic gases directly pollute the atmosphere. The continuous accumulation of residual film in the soil not only damages the soil structure of the topsoil but also hinders water and fertilizer transport, affecting soil permeability and crop growth and development, posing a significant threat to agricultural production and the agricultural environment.
[0003] Recycling waste agricultural film can improve the quality of arable land and the permeability and water permeability of the soil, effectively mature the soil, and enhance the soil's water retention, fertilizer retention and salt-alkali buffering capacity. At the same time, the recycled waste agricultural film can be reused. However, since the waste agricultural film is placed on the farmland, it is inevitable that straw, soil, gravel and other impurities will be collected together during recycling, which makes it very inconvenient to screen the agricultural film to be recycled and the impurities. Therefore, it is necessary to propose a device for recycling agricultural film. Utility Model Content
[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an agricultural film wind separator to solve the problems mentioned in the background art.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] An agricultural film air separator includes a fine screening system and a coarse screening system. The coarse screening system is located at the bottom of the fine screening system. The fine screening system includes a feeding mechanism, a discharging mechanism, and a screening drive mechanism. The feeding mechanism is located at one end of the fine screening system, and the discharging mechanism is located at the other end of the fine screening system away from the feeding mechanism. The fine screening system is driven by the screening drive mechanism. The coarse screening system includes a coarse screening outlet located at the bottom.
[0007] As a preferred technical solution, the feeding mechanism includes a fine screen inlet and a pneumatic mechanism. The fine screen inlet is located at the top of the feeding mechanism, and the pneumatic mechanism is located at the end of the feeding mechanism.
[0008] As a preferred technical solution, the fine screening system further includes a coarse screen, stirring blades, and roller tracks. The coarse screen is disposed on the inner wall of the fine screening system, the stirring blades are spirally disposed on the inner side of the coarse screen, and the roller tracks are disposed at the left and right ends of the fine screening system.
[0009] As a preferred technical solution, the screening drive mechanism includes a drive wheel mechanism, a drive motor and an auxiliary wheel mechanism. The drive wheel mechanism and the auxiliary wheel mechanism are respectively located at the front and rear ends of the roller track, and the roller track is driven to rotate by the drive motor through the drive wheel mechanism.
[0010] As a preferred technical solution, the coarse screening system further includes a spiral pusher and a discharge drive motor. The spiral pusher is located inside the coarse screening system and is driven to rotate by the discharge drive motor.
[0011] In summary, the present invention has the following main advantages:
[0012] First, by using coarse and fine screening systems, agricultural film, straw, sand and gravel that need to be recycled can be screened and separated.
[0013] Secondly, the use of the active wheel mechanism and the auxiliary wheel mechanism can ensure the stable drive of the fine screening system, thereby ensuring the screening and separation of agricultural film, straw and sand and gravel.
[0014] Third, the use of stirring blades effectively breaks down and separates agricultural film, straw, sand, and gravel, making screening easier. Attached Figure Description

[0022] Example
[0023] refer to Figures 1 to 7
[0024] The agricultural film wind separator of this embodiment includes a fine screening system 1 and a coarse screening system 2. The coarse screening system 2 is located at the bottom of the fine screening system 1. The fine screening system 1 includes a feeding mechanism 11, a discharging mechanism 12 and a screening drive mechanism 13. The feeding mechanism 11 is located at one end of the fine screening system 1, and the discharging mechanism 12 is located at the other end of the fine screening system 1 away from the feeding mechanism 11. The fine screening system 1 is driven by the screening drive mechanism 13. The coarse screening system 2 includes a coarse screening outlet 21 located at the bottom.
[0025] Because the feeding mechanism 11 includes a fine screen inlet 111 and a pneumatic mechanism 112, with the fine screen inlet 111 located at the top of the feeding mechanism 11 and the pneumatic mechanism 112 located at the end of the feeding mechanism 11, when the user uses this utility model, the pneumatic mechanism 112 is connected to a fan. After the recycled agricultural film is put into the fine screen inlet 111, the wind from the pneumatic mechanism 112 blows the recycled agricultural film toward the discharge mechanism 12.
[0026] Because the fine screening system 1 also includes a coarse screen 14, stirring blades 15, and roller tracks 16, the coarse screen 14 is respectively disposed on the inner wall of the fine screening system 1, the stirring blades 15 are spirally disposed on the inner side of the coarse screen 14, and the roller tracks 16 are respectively disposed at the left and right ends of the fine screening system 1, when the user uses this utility model, after the recycled agricultural film is put into the fine screening system 1, under the wind blown by the pneumatic mechanism 112, the recycled agricultural film will move towards the discharge mechanism 12. At the same time, the stirring blades 15 will stir the incoming agricultural film and disperse it so that the straw, sand and gravel mixed with the agricultural film can be dispersed from the agricultural film. At the same time, the straw, sand and gravel fall down due to gravity and then pass through the coarse screen 14, thereby separating the straw, sand and gravel from the agricultural film.
[0027] Because the sieving drive mechanism 13 includes a drive wheel mechanism 131, a drive motor 132, and an auxiliary wheel mechanism 133, with the drive wheel mechanism 131 and the auxiliary wheel mechanism 133 respectively located at the front and rear ends of the roller track 16, and the roller track 16 being driven to rotate by the drive motor 132 via the drive wheel mechanism 131, when the user uses this utility model, while materials such as stalks and gravel fall down due to gravity and pass through the coarse screen 14 to separate the stalks and gravel from the agricultural film, the fine screen system 1 simultaneously separates the materials through the rollers. The contact friction between the roller track 16 and the drive wheel mechanism 131 is driven by the drive motor 132 to rotate. This allows materials such as straw and gravel to fall more effectively due to the centrifugal force generated by the rotation of the fine screening system 1, thus falling into the coarse screening system 2. After screening, the lightweight agricultural film will be blown out from the discharge mechanism 12, allowing users to recycle it. Furthermore, the contact between the drive wheel mechanism 131 and the auxiliary wheel mechanism 133 and the roller track 16 ensures that the roller track 16 receives a stable driving force, thereby ensuring the efficient rotation of the fine screening system 1.
[0028] Because the coarse screening system 2 also includes a spiral pusher rod 22 and a discharge drive motor 23, the spiral pusher rod 22 is located inside the coarse screening system 2 and is driven to rotate by the discharge drive motor 23. Therefore, when the user uses this utility model, after the pile of straw and sand fall into the coarse screening system 2, the spiral blades of the spiral pusher rod 22 come into contact with the pile of straw and sand through the rotation of the discharge drive motor 23. Thus, the rotational force drives the pile of straw and sand to move towards the coarse screening outlet 21, and then they can be recycled.
