Description

Technical Field

[0001] This utility model relates to the technical field of residual film recycling equipment, specifically a residual film packaging and recycling device. Background Technology

[0002] In agricultural production, the use of plastic film has greatly increased crop yields. However, after the autumn harvest, the residual film must be cleaned up to facilitate subsequent plowing of farmland and planting of crops in the following year. Currently, the main methods for cleaning up residual film are manual cleaning and machine cleaning.

[0003] For example, CN203388004U discloses a farmland residual film recycling machine, including a frame, a toothed frame, a reeling board, and film-collecting teeth. The toothed frame is fixedly connected to the frame by U-shaped clips; the film-collecting teeth are fixed to the toothed frame by bolts; the reeling board is fixed to both sides of the toothed frame by bolts. During operation, the tractor is connected to the frame by three-point suspension. The machine is adjusted to a suitable working height, and the tractor pulls the machine forward. The reeling board separates the upright crops in the farmland, creating a clean working environment for residual film recycling. The front row of film-collecting teeth penetrates the soil shallowly to collect residual film from the surface soil, while the rear row of film-collecting teeth penetrates the soil more deeply, collecting residual film from the 5cm-10cm soil layer.

[0004] While the aforementioned agricultural film residue recycling machine can collect mulch film to a certain extent, it suffers from the following problems in practical use: First, the scraping teeth easily tear aged or thin mulch film when scraping it, causing it to break into small fragments that remain on the surface or in the shallow soil. These fragments are difficult to collect completely, requiring additional manual collection, which not only increases operating costs but also exacerbates soil microplastic pollution due to the residual fragments. Second, the machine relies on the physical scraping action of the teeth to carry the residual film. Due to the limitations of the teeth's capacity and structure, the amount carried in a single operation is limited, requiring frequent stops to clean the residual film scraped onto the teeth. This severely restricts continuous operation efficiency and makes it difficult to meet the high-efficiency recycling needs of large-scale farmland. Utility Model Content

[0005] This invention provides a residual film baling and recycling device to solve the following problems mentioned in the background art: First, when scraping residual film, the film-collecting spring teeth easily tear aged or thin mulch film, causing the residual film to break into small fragments and remain on the surface or in the shallow soil. These fragments are difficult to collect completely, requiring additional manual collection, which not only increases operating costs but also exacerbates soil microplastic pollution due to the residual fragments. Second, the recycling machine relies on the physical scraping of the spring teeth to carry the residual film. Due to the limitations of the spring teeth's capacity and structure, the amount carried in a single operation is limited, requiring frequent stops to clean the residual film scraped onto the spring teeth, severely restricting continuous operation efficiency and making it difficult to meet the high-efficiency recycling needs of large-scale farmland.

[0006] To address the aforementioned problems, this utility model provides a residual film baling and recycling device, including a frame, a traction frame hinged to the front end of the frame, and a traveling wheel provided at the rear of the frame. Inside the frame, from front to back, a film shovel, a conveying assembly, and a film collection assembly are arranged sequentially. Lifting wheels are fixedly connected to the outer wall of the front end of the frame.

[0007] Specifically, the conveying assembly includes two rotating rollers rotatably connected inside the frame. Two sprockets are symmetrically mounted on the rotating rollers. The sprockets at the same end of the rotating rollers are connected by a chain drive. Several fixed bars are connected at intervals on the outer side of the chain. A pressure roller is arranged diagonally above the rotating roller near the mulch shovel. The two ends of the pressure roller are rotatably connected to the frame by a fixedly connected rotating shaft. One end of the rotating shaft passes through the side wall of the frame and is connected to a driven gear. A drive gear meshes with one side of the driven gear. The drive gear is fixedly connected to one end of the rotating roller near the mulch shovel. A commutator is installed at the upper front end of the frame. A drive sprocket is fixedly connected to the output shaft of the commutator on the outer side of the frame. A driven sprocket is fixedly connected to one end of the rotating roller away from the mulch shovel. The drive sprocket and the driven sprocket are connected by a transmission chain.

[0008] Furthermore, the film collection assembly includes a first screen plate disposed below the rotating roller away from the film shovel, a second screen plate disposed on one side of the first screen plate, and a third screen plate slidably disposed at the lower ends of the first and second screen plates, with both ends of the first and second screen plates fixedly connected to the inner sidewall of the frame.

[0009] Furthermore, the film collection assembly also includes multiple pulleys connected to the lower surfaces of both ends of the third screen plate. A slide rail fixedly connected to the lower end of the frame is provided on the lower side of the pulleys. Several lead screw sleeves are fixedly connected to one side of the pulleys on the lower surface of the third screen plate. A lead screw is rotatably connected inside the lead screw sleeve. One end of the lead screw is rotatably connected to a limiting sleeve provided at the lower end of the frame. The other end of the lead screw is fixedly connected to the output shaft of the drive motor. The drive motor is fixedly connected to the second screen plate through a connecting plate.

[0010] Furthermore, the pressure roller includes a mounting block coaxially connected to the rotating shaft, and a plurality of pressure rods are fixedly connected to the outer end of the mounting block.

[0011] Furthermore, the lifting wheel includes a guide cylinder fixedly connected to the outer wall of the front end of the frame, a movable arm slidably connected to the lower end of the guide cylinder, a lead screw rotatably connected to the upper end of the guide cylinder, the lower end of the lead screw being threadedly connected to the upper end of the movable arm, a handle fixedly connected to the upper end of the lead screw, and an auxiliary wheel rotatably connected to the lower end of the movable arm.

[0012] Furthermore, the lead screw sleeve is provided with an internal thread hole that matches the external thread of the lead screw.

[0013] Furthermore, the roller furthest from the mulch shovel is positioned vertically higher than the roller closest to the mulch shovel.

[0014] Furthermore, the first, second, and third mesh plates are evenly provided with mesh holes.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model discloses a residual film baling and recycling device. It comprises a film shovel, a conveying component, and a film collection component. During operation, the film shovel cuts into the soil beneath the film at an inclined angle, lifting the film. The film is then conveyed backward on the conveying component. Simultaneously, the pressure rollers of the conveying component squeeze the film, crushing larger clods of soil within it. As the fixed rods are conveyed backward with the chain, the crushed soil clods and finer soil mixed with the film fall through the gaps between the fixed rods. The film then enters the film collection component from the rear end of the conveying component. This process not only ensures the integrity of the film but also separates the soil from the film, overcoming the problem in existing technologies where the film-collecting spring teeth easily tear aged or thin film when scraping residual film, causing it to break into small fragments that remain on the surface or in the shallow soil. These fragments are difficult to collect completely, requiring additional manual collection.

[0017] This utility model discloses a residual film baling and recycling device. By setting up a film collection assembly, the mulch film enters from the rear end of the conveying assembly, forming an upward-opening frame structure enclosed by a first, second, and third mesh plate and a frame. When the frame structure is full of mulch film, the tractor stops moving forward. A control switch on the tractor controls the drive motor to rotate the lead screw. The lead screw rotates within a lead screw sleeve, which in turn moves the third mesh plate along a slide rail via pulleys towards the mulch film shovel. This opens the bottom of the frame structure, allowing the collected mulch film to fall to the ground. The fallen mulch film accumulates on the ground for easy subsequent transfer. The drive motor is then reversed, causing the third mesh plate to reset, closing the bottom of the frame structure. This process allows the film collection assembly to carry a large amount of mulch film, and the unloading is quick and convenient. It overcomes the problems of existing equipment, which has a limited carrying capacity per operation, requires frequent stops to clean residual film scraped from the spring teeth, severely restricts continuous operation efficiency, and fails to meet the high-efficiency recycling needs of large-scale farmland.

[0029] The film collection assembly 6 includes a first screen plate 601 disposed below the rotating roller 501 away from the film shovel 4, a second screen plate 602 disposed on one side of the first screen plate 601, and a third screen plate 603 slidably disposed at the lower ends of the first screen plate 601 and the second screen plate 602.

[0030] The film collection assembly also includes multiple pulleys 604 connected to the lower surfaces of both ends of the third screen plate 603.

[0033] The lead screw sleeve 606 is provided with an internal thread hole that matches the external thread of the lead screw 607.

[0034] Among them, the rotating roller 501 that is far away from the mulch shovel 4 is vertically higher than the rotating roller 501 that is close to the mulch shovel 4.

[0035] Among them, the first mesh plate 601, the second mesh plate 602, and the third mesh plate 603 are evenly provided with mesh holes.

[0036] Transmission principle of the device: The power output shaft of the tractor drives the commutator 509 to rotate through the transmission shaft. In turn, the output shaft of the commutator 509 drives the drive sprocket 510 fixedly connected to it to rotate. The rotating drive sprocket 510 drives the driven sprocket 511 and the roller 501 fixedly connected to the driven sprocket 511 to rotate through the transmission chain 512. Then, the roller 501 drives another sprocket 502 and the roller 501 to rotate through the chain 503 via the sprocket 502 fixedly connected to it. At the same time, the rotating roller 501 drives the drive gear 508 to rotate through the rotating shaft 506. In turn, the drive gear 508 drives the meshing driven gear 507 to rotate, which in turn drives the pressure roller 505 to rotate. At this time, the entire conveying assembly 5 runs through a series of transmissions.

[0037] Working principle:

[0038] Before operation, the residual film baling and recycling device is connected to the rear of the tractor via a tow frame. The tractor's power output shaft is connected to the input shaft of the commutator 509 via a drive shaft. The tractor then pulls the residual film baling and recycling device to the farmland. Turning the handle 704 rotates the lead screw 703, which in turn causes the movable arm 702 to rise within the guide cylinder 701. The movable arm 702 then causes the auxiliary wheel 705 to rise, causing the film shovel 4 to tilt downwards and contact the ground. The tractor then drives the residual film baling and recycling device forward, and the film shovel 4 cuts into the soil beneath the film at an angle, scooping up the film. At this time, the rearward-rotating conveying component 5 conveys the soil and film backwards together. During this process, the pressure roller 505 squeezes the soil and film, compressing the larger portions of the film. As the soil clods are crushed and transported backward by the chain 503 along with the fixed rods 504, the crushed soil clods and finer soil mixed in with the mulch film fall through the gaps between the fixed rods 504. The mulch film is then conveyed backward on the fixed rods 504 and falls into the film collection assembly 6. Because the first mesh plate 601, the second mesh plate 602, and the third mesh plate 603 form an upward-opening frame structure with the frame 1, the mulch film falls into the frame structure from the rear end of the conveying assembly 5. Furthermore, because the first mesh plate 601, the second mesh plate 602, and the third mesh plate 603 are evenly provided with mesh holes, the residual film that falls into the frame structure will shake as the residual film packaging and recycling device moves forward, further shaking off the soil remaining on the mulch film and causing it to fall to the ground through the mesh holes.

[0039] Once the plastic film inside the frame structure is full, the tractor stops moving forward. The control switch on the tractor controls the drive motor 609 to rotate the lead screw 607. The lead screw 607 then rotates within the lead screw sleeve 606, which in turn drives the third mesh plate 603 to move towards the plastic film shovel 4 via the pulley 604 on the slide rail 605. This causes the bottom of the frame structure to open, allowing the collected plastic film to fall to the ground. The fallen plastic film accumulates on the ground for easy transport later. Then, the drive motor 609 is reversed, causing the third mesh plate 603 to reset, closing the bottom of the frame structure. The tractor is then restarted to drive the residual film baling and recycling device forward to collect the plastic film.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model.
