Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to an integrated machine for drip irrigation tape and mulch film recycling. Background Technology

[0002] In modern agricultural production, plastic film mulching and drip irrigation under mulch are widely used in the cultivation of crops such as corn and cotton due to their significant advantages in moisture retention, soil warming, weed control, water conservation, and yield increase. However, the plastic film and drip irrigation tape left in the field after crop harvest are difficult to degrade naturally. If they are not recycled in a timely or thorough manner, they will cause serious "white pollution," damage the soil structure, and affect subsequent cultivation and crop growth.

[0003] Regarding the recycling needs of agricultural mulch film and drip irrigation tape, the industry has currently developed two main technical solutions: manual recycling and mechanized recycling. Manual recycling is inefficient, labor-intensive, and costly, making it unsuitable for large-scale agricultural production. Mechanized recycling has become the mainstream development direction, but existing technologies are mostly single-function, modular specialized equipment. These mainly include two types of products: one is specialized machinery focused on drip irrigation tape recycling, which can only independently recycle drip irrigation tape and cannot simultaneously process mulch film waste; the other is mulch film recycling machines, which can only recycle mulch film and do not have drip irrigation tape recycling capabilities.

[0004] However, in practical applications, it has been found that separate recycling equipment for drip irrigation tape and mulch film requires repeated investment, and the multiple field operations and fuel consumption result in low operating efficiency and high overall costs, which does not meet the development needs of modern large-scale and intensive agriculture. In addition, most current mulch film recycling machines are mainly suitable for low-stubble crops such as cotton, and their adaptability to high-stubble (5-10cm) crops such as corn is poor. At the same time, technical problems such as incomplete separation of stubble and film and high impurity content in recycled mulch film are commonly encountered in addressing the issue of tightly entangled root stubble and mulch film.

[0005] In view of the above problems, how to improve operational efficiency, reduce overall costs, and improve the purity of recycled plastic film has become an important technical challenge that urgently needs to be solved. Summary of the Invention

Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0045] To better understand the integrated drip irrigation tape and mulch film recycling machine provided in this embodiment of the invention, its application background is first introduced. In modern agricultural production, mulch film covering and drip irrigation under film are widely used due to their advantages such as moisture retention, temperature increase, weed suppression, water saving and yield increase. However, the plastic mulch film and drip irrigation tape left in the field after crop harvest are difficult to degrade naturally. If recycling is not timely or thorough, it will lead to serious "white pollution", damage the soil structure and affect subsequent cultivation and crop growth.

[0046] Currently, there are two main methods for recycling agricultural mulch film and drip irrigation tape: manual recycling and mechanized recycling. Manual recycling is inefficient, labor-intensive, and costly, making it unsuitable for large-scale agricultural production. Mechanized recycling has become the mainstream development direction, but existing technologies are mostly based on single-function, separate specialized equipment. These mainly include two types of products: one is specialized machinery focused on drip irrigation tape recycling, which can only independently recycle drip irrigation tape and cannot simultaneously process mulch film waste; the other is mulch film recycling machines, which can only recycle mulch film and do not have the function of recycling drip irrigation tape.

[0047] However, in practical applications, it has been found that separate recycling equipment for drip irrigation tape and mulch film requires repeated investment, and the multiple field operations and fuel consumption result in low operating efficiency and high overall costs, which does not meet the development needs of modern agriculture for large-scale and intensive operations. In addition, most existing mulch film recycling machines are mainly used for low-stubble crops such as cotton, and are poorly adapted to the working conditions where corn leaves a high stubble (5-10cm) after harvest and the root stubble is tightly wrapped with the mulch film. They generally suffer from technical problems such as incomplete separation of stubble and film and high impurity content in the recycled mulch film.

[0048] In view of the above problems, embodiments of the present invention provide an integrated machine for drip irrigation tape and mulch film recycling, which has the advantages of high operating efficiency, high purity of recycled mulch film, and low overall cost.

[0049] The following is combined with Figures 1 to 12 This invention describes an integrated machine for recycling drip irrigation tape and plastic film.

[0050] Reference Figure 1A drip irrigation tape and mulch film recycling integrated machine includes a walking mechanism 10 and a floating film stubble breaking mechanism 20, a film lifting mechanism 30, a film debris separation mechanism 40, a mulch film collection mechanism 50, and a drip irrigation tape winding mechanism 60 connected to the walking mechanism 10. The floating film stubble breaking mechanism 20 includes a rotatable rotary tiller 21 and a stubble breaking blade 22. The rotary tiller 21 acts on the soil layer to float the film, and the stubble breaking blade 22 is used to crush crop stubble. The film lifting mechanism 30 is located downstream of the floating film stubble breaking mechanism 20 and is used to collect and transport the mixture of film, stubble, and soil after being crushed by the floating film stubble breaking mechanism 20. The film debris separation mechanism 40 is located downstream of the film lifting mechanism 30 and is used to separate the mulch film from the mixture. The mulch film collection mechanism 50 is located downstream of the film debris separation mechanism 40 and is used to collect the mulch film separated by the film debris separation mechanism 40. The drip irrigation tape winding mechanism 60 is used to wind up the drip irrigation tape when the walking mechanism 10 is moving.

[0051] In practical applications, as the walking mechanism 10 propels the entire machine forward, the front-end floating film breaking mechanism 20 breaks the soil layer pressing the film with rotary tillage blades 21 to achieve floating film. Simultaneously, the breaking blades 22 crush the root stubble of crops with high stubble retention, such as corn. The film lifting mechanism 30 then collects the mixture of film, stubble, and soil and transports it backward. The film and impurity separation mechanism 40 separates the mixture to obtain pure mulch film. The mulch film collection mechanism 50 collects the separated mulch film. The drip irrigation tape winding mechanism 60 completes the winding of the drip irrigation tape simultaneously with the movement of the entire machine. All functional mechanisms work together and operate continuously to complete the integrated recycling of mulch film and drip irrigation tape in one go.

[0052] Compared to related technologies, this integrated drip irrigation tape and mulch film recycling machine achieves a high degree of integration of drip irrigation tape recycling and mulch film recycling functions. It can complete the simultaneous recycling of two types of waste, drip irrigation tape and mulch film, in a single field visit, reducing the frequency of machine visits and fuel consumption, improving field operation efficiency, and reducing overall recycling costs. At the same time, it adopts a technical solution that combines rotary tillage and stubble breaking with film and impurity separation, effectively solving the technical problems of tightly wrapped stubble and mulch film under high stubble conditions, incomplete film and impurity separation, and high impurity content in the recycled mulch film, thus improving the purity of recycled mulch film.

[0053] The specific structural forms of each mechanism will be described below with reference to the accompanying drawings.

[0054] In one example of the present invention, the walking mechanism 10 includes a frame 11, walking wheels 12 and depth-limiting wheels 13; wherein, the front end of the frame 11 along the traveling direction is connected to a traction frame 14 for connecting with the walking equipment; the walking wheels 12 are connected to the rear end of the frame 11 along the traveling direction; and the depth-limiting wheels 13 are connected to the front end of the frame 11 along the traveling direction.

[0055] In detail, the towing frame 14 can be connected to the suspension frame of agricultural power equipment such as tractors to achieve the traction of the whole machine; the walking wheels 12 are used to support the rear of the frame 11 to ensure smooth operation in the field and movement; while the depth limiting wheels 13 are used to limit the working height of the front end of the frame 11, thereby controlling the soil penetration depth of the floating film breaking mechanism 20 and the film lifting mechanism 30, and avoiding the effect of film-soil separation and recycling due to improper depth.

[0056] In one example of the present invention, reference is made to Figure 2 The floating film stubble breaking mechanism 20 also includes a gearbox 23 and a cutter shaft 24; wherein, the gearbox 23 is provided with a power input end and a power output end, the power input end of the gearbox 23 is used to drive the connection with the power mechanism, the cutter shaft 24 is arranged along a second direction perpendicular to the direction of travel and is rotatably connected to the traveling mechanism 10, the cutter shaft 24 is drively connected to the power output end of the gearbox 23, and the rotary tiller 21 and the stubble breaking blade 22 are fixedly connected to the cutter shaft 24.

[0057] With this configuration, the power of the power mechanism is transmitted to the cutter shaft 24 via the gearbox 23 to drive the cutter shaft 24 to rotate. The cutter shaft 24 drives the rotary tiller blade 21 and the stubble breaker blade 22 to rotate synchronously, thereby completing the floating film and stubble breaking operations simultaneously during the movement of the machine. The rotary tiller blade 21 can break the soil layer pressing the film on both sides, causing the film to loosen and float. The stubble breaker blade 22 can crush the crop stubble left in the field, solving the technical problem of the stubble and film being entangled and difficult to separate. This provides stable and smooth operating conditions for the subsequent film lifting, film impurity separation and recycling processes, improving the overall recycling efficiency and the purity of the film.

[0058] It is understood that the aforementioned power mechanism can be either the power unit built into the drip irrigation tape and mulch film recycling integrated machine, or it can be the power output system of external agricultural power equipment such as a tractor. The specific design can be tailored to actual needs, which will be further elaborated below and will not be discussed here. Furthermore, the rotary tillage blade 21 and stubble-breaking blade 22 are commonly used agricultural machinery blades; their specific structures and working principles can be found in existing technologies, and will not be elaborated upon in this embodiment of the invention.

[0059] Furthermore, the cutter shaft 24 extends to opposite sides of the transmission 23, and the cutters, including rotary tiller blades 21 and stubble breaker blades 22, are divided into at least two cutter groups, with multiple cutter groups distributed on the cutter shaft 24 on both sides of the transmission 23; the cutter groups include two rotary tiller blades 21 located on both sides and at least one stubble breaker blade 22 located between the two rotary tiller blades 21.

[0060] With this setup, the rotary tillers 21 on both sides can break through the soil layer of the plastic film to achieve floating film, while the stubble-breaking blade 22 in the middle can simultaneously crush the crop stubble. Multiple blade sets can achieve simultaneous operation on multiple ridges, completing the floating film and stubble breaking treatment on multiple ridges in one go, improving the operation width and field recycling efficiency.

[0061] In this embodiment, two cutter sets are provided to enable simultaneous operation on both rows.

[0062] In one example of the present invention, reference is made to Figure 3 The film-lifting mechanism 30 includes a film-lifting shovel 31 and an adjusting member; wherein, the front end of the film-lifting shovel 31 along the traveling direction is provided with a shovel mouth corresponding to the knife group, and the other end is connected to the film impurity separation mechanism 40, and the angle between the film-lifting shovel 31 and the traveling direction is adjustable; the adjusting member is connected to the film-lifting shovel 31 to adjust the angle between the film-lifting shovel 31 and the traveling direction.

[0063] With this configuration, during the machine's movement, the film-lifting shovel 31 can catch the mixture of film, stubble, and soil after the floating film and stubble breaking process, and transport it to the subsequent film-stubble separation mechanism 40. The angle between the film-lifting shovel 31 and the working direction can be adjusted by the adjusting component, thereby adapting to different field working conditions, ensuring a smooth film-lifting process, complete and unrecorded film pickup, and effectively improving the machine's overall operational adaptability and recycling stability.

[0064] In detail, the end of the film lifting shovel 31 away from its opening can be hinged to the traveling mechanism 10 or the film impurity separation mechanism 40 via a pin 32. The adjusting component is configured as a lifting cylinder. The extension and retraction of the lifting cylinder drives the film lifting shovel 31 to rotate around the pin 32, thereby adjusting the angle of the film lifting shovel 31.

[0065] In one example of the present invention, reference is made to Figure 4 The membrane impurity separation mechanism 40 includes a chain vibrating screen 41 and an airflow screening device 42. One end of the chain vibrating screen 41 is connected to the rear end of the film lifting shovel 31 along the travel direction, and the other end extends to the residual film inlet of the mulch film collection mechanism 50. The screen surface of the chain vibrating screen 41 is configured to circulate between the film lifting shovel 31 and the mulch film collection mechanism 50, thereby screening and conveying the above-mentioned film, stubble, and soil mixture. The airflow screening device 42 is disposed between the chain vibrating screen 41 and the residual film inlet of the mulch film collection mechanism 50 and is used to provide airflow to introduce the mulch film into the mulch film collection mechanism 50.

[0066] With this setup, the mixture of film, stubble, and soil can be continuously conveyed and initially screened by the chain vibrating screen 41, separating most of the soil particles. Then, in conjunction with the directional airflow generated by the airflow screening device 42, the lightweight film is blown to the film collection mechanism 50, allowing the heavy stubble and impurities to settle and be discharged naturally. This forms a two-stage separation mode of mechanical screening plus airflow cleaning, which significantly improves the film-impurity separation effect and the purity of film recycling, and solves the technical problem of incomplete film-impurity separation.

[0067] In detail, the chain vibrating screen 41 includes a chain screen 411, a screen sprocket 412, and a vibration guiding structure; wherein, the chain screen 411 is configured to be connected end to end, and a screen chain 413 with a matching shape is connected to the chain screen 411; the screen sprocket 412 is located at both ends of the chain screen 411 and is connected to the power mechanism for transmission, and the screen chain 413 is wound around the screen sprocket 412; the vibration guiding structure includes a rotatable cam, which is located below the screen surface of the chain screen 411 and is used to periodically lift and drop the chain screen 411 through its own rotation.

[0068] With this configuration, the screen sprocket 412 can drive the screen chain 413 and the chain screen 411 to perform closed-loop circulation, realizing the continuous conveying and preliminary screening of the film, stubble, and soil mixture from the film lifting shovel 31 to the film collection mechanism 50. The cam component of the vibration guide structure can periodically lift and lower the screen surface during the screen surface movement, so that the chain screen 411 generates continuous and stable vibration, which enhances the soil screening effect, effectively reduces the soil content of the film, and lays the foundation for subsequent airflow cleaning and film collection.

[0069] Furthermore, the vibration guiding structure also includes a rotating shaft, which is rotatably connected to the frame 11 of the traveling mechanism 10; the cam component may include multiple guide wheels arranged around the rotating shaft at different phase angles. With this configuration, when the rotating shaft rotates, each guide wheel contacts the chain screen 411 in sequence, causing the chain screen 411 to periodically rise and fall, thereby creating a continuous and uniform vibration effect on the screen surface. The rolling contact between the guide wheels and the chain screen 411 reduces frictional resistance and component wear at the contact points, minimizes problems such as screen surface movement jamming and abnormal noise, and improves the operational reliability and service life of the vibration guiding structure.

[0070] In one example of the present invention, reference is made to Figure 5 The airflow screening device 42 includes an air duct plate 421 and a blower 422. The air duct plate 421 is arranged at the end of the chain vibrating screen 41 away from the film lifting shovel 31. The air duct plate 421 has an air duct and an air outlet 423 that communicates with the air duct is provided at the end near the screen surface of the chain vibrating screen 41. The air outlet 423 faces the residual film inlet of the film collection mechanism 50. The air outlet of the blower 422 communicates with the air duct in the air duct plate 421.

[0071] With this configuration, the airflow generated by the blower 422 passes through the internal air duct of the air duct plate 421 and is output through multiple air outlets 423 facing the residual film inlet of the mulch film collection mechanism 50, forming a stable and controllable directional airflow field. By utilizing the density difference between the mulch film and soil clods and stubble, the lightweight mulch film, which has been preliminarily screened by the chain vibrating screen 41, is blown into the mulch film collection mechanism 50, while the heavy soil and stubble impurities are naturally discharged under gravity, realizing the secondary cleaning and separation of film, soil and stubble, and improving the purity of mulch film recycling.

[0072] In detail, the air duct plate 421 is arranged at the rear end of the chain vibrating screen 41 along the direction of travel, and the fan 422 is fixedly connected to the air duct plate 421.

[0073] In one example of the present invention, reference is made to Figure 6 The plastic film collection mechanism 50 includes a baling chamber 51 and a baling shaft 52; wherein, the baling chamber 51 has the aforementioned residual film inlet on one side and a discharge port on the other side, and the discharge port is connected to an openable and closable discharge door 511; the baling shaft 52 is arranged along the second direction and rotatably connected to the baling chamber 51, and multiple baling shafts 52 are arranged in parallel and alternately.

[0074] With this setup, the mulch film is transported from the residual film inlet to the packing bin 51 under the action of the airflow screening device 42. Multiple parallel and alternating bundling shafts 52 rotate synchronously, which can continuously squeeze and roll the mulch film entering the bin, bundling the loose mulch film into regular film bundles, which facilitates the subsequent storage, transportation and resource reuse of the mulch film. The openable and closable unloading door 511 can facilitate the unloading and transfer of the film bundles after they are formed.

[0075] In detail, multiple baling shafts 52 can be evenly arranged in the circumferential direction in the packing chamber 51 to form a semi-enclosed rolling cavity with the opening facing the residual film inlet. Some of the baling shafts 52 are located near the residual film inlet to guide the mulch film conveyed by the airflow screening device 42 into the rolling cavity. When the multiple baling shafts 52 rotate, they drive the mulch film to circulate, rub, and agglomerate into a film core, thereby pulling the subsequent mulch film to continue to wind into a roll.

[0076] Furthermore, a pressure sensor can be installed in the packing chamber 51. The pressure sensor can monitor the compactness pressure parameters of the film roll forming in the packing chamber 51 in real time. When the film bundle is wound to the preset pressure threshold and reaches the standard compactness, it indicates that the round bundle has been compacted and formed. At this time, the unloading door 511 can be opened to discharge the round bundle of film.

[0077] In one example of the present invention, one side of the unloading gate 511 is hinged to the unloading port, and a driving member 512 is connected between the unloading gate 511 and the unloading port for driving the unloading gate 511 to open and close the unloading port around the hinge axis.

[0078] With this configuration, the unloading gate 511 can be automatically opened and closed via the hinged drive component 512, eliminating the need for manual intervention and improving the overall automation level of the machine. When the unloading gate 511 is closed, it can seal the unloading port, ensuring the airtightness of the baling chamber 51 and preventing the mulch film from leaking and scattering during the winding and bundling process. When the unloading gate 511 is open, it can open the unloading port and discharge the neatly formed bundles of film, realizing the integrated continuous operation of mulch film collection, bundling, and unloading, thus improving the efficiency and convenience of mulch film recycling in the field.

[0079] In detail, the drive component 512 can be any form of linear drive element, including cylinders, hydraulic cylinders, electric actuators, etc. One end of the drive component 512 is hinged to the frame 11 of the walking mechanism 10, and the other end is hinged to the unloading gate 511. It is used to drive the unloading gate 511 to rotate around the hinge axis through its own linear telescopic motion, thereby realizing the automatic opening and closing of the unloading port.

[0080] It is understandable that the chain vibrating screen 41 and the bundling shaft 52 can be equipped with independent power mechanisms to achieve individual drive, or they can be connected by transmission components such as gears and sprockets to achieve unified power supply, so as to simplify the overall structure layout and improve the coordination between mechanisms.

[0081] In one example of the present invention, reference is made to Figure 6 The drip irrigation tape and mulch film recycling integrated machine also includes a transmission mechanism 53, a chain vibrating screen 41 and multiple bundling shafts 52 connected to the power mechanism through the transmission mechanism 53.

[0082] In detail, the transmission mechanism 53 includes a power connector 530, a universal drive shaft 531, a drive shaft 533, a drive sprocket 534, a conveyor sprocket 535, a baling sprocket 536, and a transmission chain 537. The power connector 530 is connected to the traveling mechanism 10, and its power input end is used to connect to the power mechanism. The universal drive shaft 531 is arranged along the traveling direction, with one end connected to the power output end of the power connector 530 and the other end connected to the input end of the angle transmission box 532. The drive shaft 533 is arranged along a second direction and connected to the output end of the angle transmission box 532. The drive sprocket 534 is connected to the drive shaft 533. The conveyor sprocket 535 is connected to the screen sprocket 412 via a connecting shaft. The baling sprocket 536 is connected to the baling shaft 52. The transmission chain 537 is wound between the drive sprocket 534, the conveyor sprocket 535, and the baling sprocket 536.

[0083] This configuration allows the power output from the power mechanism mounted on or externally mounted on the walking mechanism 10 to be transmitted via the power connector 530, universal drive shaft 531, and angle transmission box 532. The power is then transmitted synchronously through the drive sprocket 534 and the transmission chain 537 to drive the conveying sprocket 535 and the baling sprocket 536 to rotate. This provides the same power source for the screening and conveying operation of the chain vibrating screen 41 and the winding and baling operation of the baling shaft 52. This ensures that the cycle time of each process, including film impurity separation, film collection, and winding and baling, is coordinated and seamlessly connected. It simplifies the overall power system structure, reduces redundant parts and energy consumption, and improves the stability and efficiency of the integrated continuous operation of film recycling.

[0084] Furthermore, the transmission mechanism 53 may also include a tension sprocket 538, which meshes with the outer side of the transmission chain 537, and the installation position of the tension sprocket 538 can be adjusted according to actual needs. The tension sprocket 538 can apply a constant preload to the transmission chain 537, reducing problems such as tooth skipping, chain slippage, or transmission lag caused by loosening or elongation of the transmission chain 537, and ensuring the synchronicity, stability, and reliability of power transmission between the drive sprocket 534, the conveyor sprocket 535, and the bundling sprocket 536.

[0085] In one example of the present invention, reference is made to Figures 7 to 11 The drip irrigation tape winding mechanism 60 includes a guiding structure 61 and a winding structure 62; wherein, the guiding structure 61 is used to guide the drip irrigation tape to be recycled; the winding structure 62 is located downstream of the guiding structure 61 and is used to wind up the drip irrigation tape after it has been guided by the guiding structure 61.

[0086] With this configuration, the guide structure 61 can orient and regulate the drip irrigation tape to be recycled in the field, and constrain its path, so as to avoid problems such as deviation, entanglement, and tearing during the recycling and transportation process, and ensure the stable and smooth transportation trajectory of the drip irrigation tape. The winding structure 62 is located downstream of the guide structure 61, and can continuously and orderly wind and gather the drip irrigation tape after it has been guided, so as to realize the automated winding and storage of the drip irrigation tape, thereby simultaneously completing the classification and integrated recycling of agricultural residual film and drip irrigation tape, expanding the applicable scenarios and recycling range of the whole machine, improving field operation efficiency, and reducing the overall recycling cost and field recycling intensity.

[0087] Furthermore, the guide structure 61 includes an anti-deviation frame and at least two guide members 613; wherein, the anti-deviation frame is connected to the traveling mechanism 10; the multiple guide members 613 are arranged at intervals in a second direction perpendicular to the traveling direction and are slidably connected to the anti-deviation frame, for providing guidance for different drip irrigation tapes respectively; the adjustment component is used to adjust the position of the guide members 613 in the second direction.

[0088] With this configuration, multiple guides 613 are arranged at intervals along a second direction perpendicular to the direction of travel. This allows for the independent guidance and sorting of multiple rows of drip irrigation tape laid in the field, improving recycling efficiency and preventing multiple drip irrigation tapes from tangling, interfering, or knotting during recycling and transportation. At the same time, the position adjustment of the guides 613 ensures that the drip irrigation tape is neatly and tightly wound onto the tape reel 621 layer by layer, without overlap or gaps, thus improving the regularity of the roll.

[0089] Furthermore, the guide member 613 is configured as a rotatable guide wheel, with its rotation axis arranged along the second direction and a groove 614 for accommodating the drip irrigation tape on its outer circumference. This configuration allows the guide wheel to convert the sliding friction during drip irrigation tape transport into rolling friction, reducing the frictional resistance between the drip irrigation tape and the guide member, improving the smoothness of tape winding, and reducing component wear. The groove 614 on the outer circumference of the guide wheel provides radial and directional constraints on the drip irrigation tape, limiting its transport trajectory and preventing lateral movement, detachment from the guide member 613, or interference from multiple drip irrigation tapes entangled together.

[0090] In one example of the present invention, the adjusting assembly includes a lead screw 615, two mounting seats 616, and a first motor 617; wherein, the lead screw 615 is arranged along a second direction and rotatably connected to the anti-deviation frame, and the lead screw 615 is provided with two threaded portions 6151 arranged in the second direction; the two mounting seats 616 are provided with internal threads and are correspondingly connected to the two threaded portions 6151, and two guide members 613 are correspondingly connected to the two mounting seats 616 through bearings 6161; the first motor 617 is connected to the lead screw 615 and is used to drive the lead screw 615 to rotate; the mounting seats 616 are slidably connected to the anti-deviation frame; the internal threads of the two mounting seats 616 have the same direction of rotation, and the threads of the threaded portions 6151 have opposite directions of rotation; or, the internal threads of the two mounting seats 616 have opposite directions of rotation, and the threads of the threaded portions 6151 have the same direction of rotation.

[0091] With this configuration, when the first motor 617 drives the lead screw 615 to rotate, the two threaded sections 6151 with opposite directions of rotation engage with the threads of the mounting base 616 to drive the two guide members 613 to move synchronously towards each other or away from each other along the second direction, thereby adjusting the spacing between the guide members 613. Moreover, this electric adjustment method does not require manual operation, has high adjustment efficiency and accurate positioning, and can quickly adapt to diverse operating conditions with different planting row spacings and different drip irrigation tape laying spacings in the field.

[0092] In detail, the anti-deviation frame includes a support member 611 and an anti-deviation rod 612; wherein, there are two support members 611, and the two support members 611 are arranged at intervals in the second direction, and the bottom end of the support member 611 is connected to the traveling mechanism 10; the anti-deviation rod 612 is arranged along the second direction and its two ends are respectively connected to the top ends of the two support members 611; a sliding sleeve 6162 can be fixedly connected to the mounting base 616, and by making the sliding sleeve 6162 slidably sleeved on the anti-deviation rod 612, the sliding connection between the mounting base 616 and the anti-deviation frame can be realized.

[0093] Furthermore, the two threaded portions 6151 are provided with limiting bosses 6152 at opposite ends, and the mounting base 616 can abut against the limiting bosses 6152 and be limited. This arrangement can constrain and limit the movement of the mounting base 616, preventing the mounting base 616 from disengaging from the threaded mating area due to excessive travel during the adjustment driven by the lead screw 615, or from having a hard collision with the frame 11 or other components.

[0094] In detail, the winding structure 62 includes a winding frame 621 and a second motor 622; wherein, the winding frame 621 is arranged along the second direction and rotatably connected to the traveling mechanism 10, and the winding frame 621 corresponds to the guide member 613; the second motor 622 is drivenly connected to the winding frame 621 and is used to drive the winding frame 621 to rotate.

[0095] Furthermore, the tape winding frame 621 includes a central shaft 6211 and multiple winding rods 6212 arranged around the central shaft 6211. The multiple winding rods 6212 are arranged in a polygonal structure (such as a quadrilateral structure formed by four winding rods 6212, a triangular structure formed by three winding rods 6212, etc.), which can play a buffering role when winding the tape during the overall rotation of the tape winding mechanism and prevent tape breakage.

[0096] Furthermore, there are two coaxially arranged tape reel holders 621, and the opposite ends of the two tape reel holders 621 are detachably connected to movable baffles 6213 so that after the preset amount of winding is reached, the movable baffles 6213 can be removed to unload the rolled drip irrigation tape.

[0097] It is understandable that the movable baffle 6213 and the tape reel 621 can be locked by nuts or connected by hinges or buckles; no specific restrictions are made here.

[0098] To improve the ease of unloading, refer to Figure 8 and Figure 9In another example of the present invention, the tape reel 621 further includes a fixed baffle 6216 and a driving component; wherein, the fixed baffle 6216 is disposed inside the movable baffle 6213 and fixedly connected to the central shaft 6211, and the fixed baffle 6216 is provided with multiple connecting rods 6217 corresponding to the position and number of the winding rod 6212, the connecting rods 6217 being arranged radially along the central shaft 6211; the movable baffle 6213 includes a stop rod 6214 and a sliding member 6215; the sliding member 6215 is connected to the central shaft 6211. 11. A sliding connection is made and the component can slide close to or away from the fixed baffle 6216; the position and number of the baffle rod 6214 correspond to those of the coil rod 6212 and are arranged radially along the central axis 6211, and the end of the baffle rod 6214 is hinged to the sliding member 6215; one end of the coil rod 6212 is hinged to the connecting rod 6217, and the other end is hinged to the baffle rod 6214 at the corresponding position and can slide along the baffle rod 6214; the driving component is connected to the sliding member 6215 for driving the sliding member 6215 to slide along the central axis 6211.

[0099] In practical applications, when the tape reel 621 is in operation, the driving component drives the sliding member 6215 to slide along the central axis 6211 away from the fixed baffle 6216. Under the linkage of the connecting rod 6217 and the stop rod 6214, each reel 6212 unfolds outward around the hinge point, forming a stable large-diameter reel structure, which can be used to wind drip irrigation tape and complete the winding operation. After winding, the driving component drives the sliding member 6215 to slide along the central axis 6211 towards the fixed baffle 6216, and the sliding member 6215 drives the stop rod 621. 4. The coiling rod 6212, constrained by the connecting rod 6217 and the stop rod 6214, rotates around the hinge point toward the central axis 6211 and slides along the stop rod 6214, forming a tapered structure with a gradually decreasing diameter from the fixed baffle 6216 to the movable baffle 6213. The completed drip irrigation tape loses its support and can slide down along the coiling rod 6212 to achieve automatic unloading. Then, the driving component drives the sliding member 6215 to slide away from the fixed baffle 6216 along the central axis 6211, and each coiling rod 6212 unfolds to start the next winding operation.

[0100] Compared to related technologies, by driving the sliding member 6215 to slide back and forth along the central axis 6211 through the drive component, and coordinating the linkage constraint of the connecting rod 6217 and the stop rod 6214, the winding rod 6212 can flexibly switch between radially open and closed states: in the working state, the winding rod 6212 unfolds outward to form a stable large-diameter reel, reliably carrying the drip irrigation tape to complete the winding operation; when unloading, the winding rod 6212 retracts towards the center and forms a conical structure, causing the wound drip irrigation tape to lose support and automatically slide down along the winding rod 6212, achieving unloading without manual disassembly, greatly improving the efficiency and convenience of winding, unwinding and unloading operations.

[0101] It is understood that the drive component can be configured as any form of linear drive element such as hydraulic cylinder, pneumatic cylinder, electric actuator, etc., and the specific choice can be made according to actual needs. No specific restrictions are imposed here. In addition, the drive component can be integrated into the central shaft 6211 to ensure structural compactness and appearance, while avoiding interference with the winding operation and improving the integration level and operational safety of the device.

[0102] Furthermore, the walking mechanism 10 is rotatably connected to an output shaft 623 via a support 627. The second motor 622 is connected to the output shaft 623, and a drive sprocket 624 is connected to the output shaft 623. A driven sprocket 625 is connected to the center of the central shaft, and two tape winding frames 621 are distributed on both sides of the driven sprocket 625. The drive sprocket 624 and the driven sprocket 625 are connected by a drive chain 626. With this configuration, the rotational power output by the second motor 622 can be transmitted to the tape winding frame 621 through the drive sprocket 624, drive chain 626, and driven sprocket 625, thereby driving the tape winding frame 621 to rotate.

[0103] In a further example of the present invention, the drip irrigation tape and mulch film recycling integrated machine also includes a ditch opener 70; the ditch opener 70 is connected to the bottom of the walking mechanism 10 and located downstream of the film lifting mechanism 30, and is used to perform ditching operations, break the soil, loosen the ridges, and pre-loosen the soil.

[0104] In a further example of the present invention, reference is made to Figure 1 and Figure 12 The drip irrigation tape and mulch film recycling integrated machine also includes a soil covering and compaction mechanism 80. The soil covering and compaction mechanism 80 is connected to the bottom of the walking mechanism 10 and located downstream of the furrow opener 70, and is used for soil covering and compaction after furrowing. With this configuration, the soil covering and compaction mechanism 80 is arranged downstream of the furrow opener 70, which can closely follow the furrowing operation to complete the backfilling and compaction of stubble and soil after the operation. It gathers the fine soil and stubble discharged during the operation and covers the furrows or seedling strips after the recycling operation, realizing local soil covering and compaction. It is particularly suitable for autumn recycling operations, which can reduce the exposure of the ground surface, prevent soil wind and water erosion, and the crushed stubble can be used as straw, realizing the function of straw mulching and returning to the field.

[0105] In detail, the soil covering and compaction mechanism 80 includes two covering rollers 81 spaced apart in the direction of travel; the outer circumference of the covering rollers 81 is provided with a spiral soil covering strip 82, and the soil covering strips 82 on the two covering rollers 81 rotate in opposite directions. With this arrangement, the spiral soil covering strips 82 with opposite outer circumferences can synchronously gather and push the soil on both sides towards the middle furrow as the covering rollers 81 move and rotate with the machine, so as to realize the backfilling and covering of soil after the furrowing operation.

[0106] In a further example of the present invention, the drip irrigation tape and mulch film recycling integrated machine also includes a controller 90 and a sensor group; wherein the sensor group includes: a torque sensor disposed on the drive shaft 533 for monitoring the overall machine operating resistance; a pressure or tension sensor and a weight sensor disposed on the drip irrigation tape winding frame 621 for monitoring the winding state; and a pressure sensor disposed on the mulch film bundling mechanism for monitoring the winding state of the mulch film in the bundling chamber 51.

[0107] The controller 90 is capable of: sending commands to the transmission system of agricultural power equipment (such as tractors) based on torque sensor signals and through algorithm processing, to achieve adaptive adjustment of forward speed (decelerating when resistance increases and accelerating when resistance decreases); controlling the spacing between guide members 613 and the unloading of drip irrigation tape based on pressure or tension sensors and weight sensors on the tape reel 621; controlling the baling and unloading process based on pressure sensor signals in the baling bin 51, and can also realize functions such as automatically lifting the film shovel 31 at the edge of the field.

[0108] In addition, during operation, the controller 90 can calculate and adjust the winding speed of the winding frame 621 based on the real-time operating speed obtained by the navigation system, so as to ensure that the winding speed is synchronized with the machine's forward speed.

[0109] During operation, the drip irrigation tape laid between the rows is manually pulled into the pick-up end of the winding mechanism. The central controller 90 calculates and adjusts the speed of the servo motor driving the tape winding frame 621 based on the real-time operating speed obtained from the Beidou navigation system, ensuring that the winding speed is synchronized with the machine's forward speed. The first motor drives the lead screw 615 to rotate according to a preset program, which drives the guide wheel to slowly reciprocate along the axial direction of the tape winding frame 621, ensuring that the drip irrigation tape is neatly and tightly wound layer by layer on the tape winding frame 621 without overlap or gaps, improving the roll regularity. When the detection value of the weight sensor on the tape winding frame 621 reaches the preset threshold, the controller 90 issues an audible and visual alarm, and the operator can stop the machine, release the movable baffle 6213, and unload the fully wound drip irrigation tape.

[0110] It is understood that those skilled in the art can combine the different embodiments or examples described herein with the features of the different embodiments or examples without contradiction.

[0111] The integrated drip irrigation tape and mulch film recycling machine provided by this invention achieves a high degree of integration of drip irrigation tape recycling and mulch film recycling functions. A single field visit can simultaneously recycle both drip irrigation tape and mulch film waste, reducing the frequency of machine visits and fuel consumption, improving field operation efficiency, and lowering overall recycling costs. Simultaneously, the technical solution combining rotary tillage and stubble breaking with film-impurity separation effectively solves the technical challenges of tightly entangled root stubble and mulch film under high stubble retention conditions, resulting in incomplete film-impurity separation and high impurity content in the recycled mulch film, thus improving the purity of the recycled mulch film.

[0112] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit it. Although the present invention 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 of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
