Description

Technical Field

[0001] This invention relates to the field of agricultural machinery engineering technology, specifically to a suspended pneumatic deep film recycling machine. Background Technology

[0002] Mulching technology has become an indispensable and important technical measure in agricultural production in arid and semi-arid regions due to its significant advantages such as warming and moisture retention, suppressing weed growth, and increasing crop yield. However, with the large-scale promotion and application of mulch film, the problem of residual film pollution has become increasingly prominent. A large amount of broken and aged agricultural mulch film is left in the field soil, which not only damages the soil structure, hinders water transport and crop root growth, leading to crop yield reduction, but also threatens the sustainable development of the agricultural ecological environment. Therefore, the development of efficient and reliable residual film recycling machinery to realize the mechanized cleaning and resource utilization of residual agricultural film has become a key technical problem that urgently needs to be solved in the field of agricultural engineering. Existing residual film recycling machines have the following main shortcomings: Low collection and conveying efficiency: Traditional residual film recycling machines mostly use fixed spring teeth or nail teeth for collection. Due to the undulating terrain in the field, it is difficult for the fixed collection device to maintain the optimal contact distance with the ground. When the ground is uneven, it is easy to miss or over-collect the film, resulting in excessive resistance. In addition, the collected residual film is often mixed with a large amount of soil and straw. Existing equipment lacks an effective real-time separation mechanism, which causes impurities to be collected together with the residual film, increasing the difficulty of subsequent cleaning and transportation costs. At the same time, the existing device uses a hard film-lifting shovel to contact the residual film, which will further break the residual film and is not conducive to improving the collection efficiency of the residual film. Unstable power transmission and poor adaptability: Many chain-driven or roller-driven recycling machines use a single power input shaft to transmit power to each working part through a complex chain or belt. When encountering sudden changes in ground resistance (such as encountering stones or hard soil), this transmission method is prone to causing the transmission system to jam, slip, or even be damaged. At the same time, the rotation speed of the picking roller is affected by the tractor's walking speed and cannot be adjusted independently, making it difficult to ensure that the best picking effect is maintained at different operating speeds. Unloading and packaging difficulties: Some equipment uses centrifugal force to throw out residual film, but because the residual film is light and soft and easy to entangle, it often cannot be easily removed from the picking parts, resulting in blockage. In addition, there is a lack of efficient impurity removal methods for the collected residual film, resulting in excessive impurity content in the packaged material, which reduces its recycling value. Poor crushing and guiding effect: Existing crushing mechanisms mostly focus only on physical tearing and ignore the movement law of the residual film in the airflow field. If the residual film after crushing is not guided by appropriate wind pressure, it is easy to accumulate in the crushing chamber or wrap around the cutter shaft, affecting the stability of continuous operation. To address the aforementioned issues, this application provides a suspended pneumatic deep film recycling machine, which aims to solve the technical bottlenecks in existing technologies, such as poor pickup effect, high impurity content, unreasonable power matching, and easy clogging, through unique wind pressure-assisted crushing, floating adaptive film collection, and multi-stage impurity removal design, thereby achieving efficient and clean recycling of residual film. Summary of the Invention

[0003] The purpose of this invention is to provide a suspended pneumatic deep film recovery machine to solve the problems of poor pickup effect, high impurity content, unreasonable power matching and easy clogging mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a suspended pneumatic deep film recycling machine, comprising a traction frame, rotating traveling wheels mounted on the lower surfaces of both ends of the traction frame, a reducer fixedly mounted on one end of the traction frame, and the output end of the reducer connected to a first transmission shaft, a guide bin fixedly disposed on the inner surface of the middle section of the traction frame, and a rotating guide drive wheel mounted on the outer surface of the middle section of the traction frame, with one end of the shaft of the guide drive wheel located inside the guide bin, and a screw rod fixedly connected to the one end of the shaft of the guide drive wheel located inside the guide bin, an opening provided on the outer surface of the guide bin, and a baffle fixedly disposed on the outer surface of the guide bin with the opening, one end of the first transmission shaft connected to the guide drive wheel via a transmission belt, and the other end of the first transmission shaft connected to a crushing drive wheel via a transmission belt; The walking wheels can also compact the ground after the film collection is completed while supporting the movement of the traction frame, so as to ensure soil moisture.

[0005] The middle section of the traction frame is equipped with a crushing mechanism, which assists in blowing the straw by generating airflow during the crushing process. The crushing mechanism includes a crushing drive wheel, which is rotatably mounted on the outer surface of the traction frame. One end of the shaft of the crushing drive wheel passes through the inner surface of the traction frame, and a crushing roller is fixedly connected to one end of the shaft of the crushing drive wheel inside the traction frame. Crushing blocks are fixedly provided on the outer surface of the crushing roller. A floating film collection mechanism is provided at one end of the traction frame. Through a separate power setting and adaptive angle changes, it can achieve efficient floating collection of residual film. The floating film collection mechanism includes: a swing rod, which is rotatably mounted on the outer surface of the traction frame. A rotating collection cylinder is installed at one end of the swing rod and is located on the inner side of the traction frame. A rotating collection tooth is installed inside the collection cylinder. A motor is fixedly installed on the outer surface of the swing rod on one side, and the output shaft of the motor is fixedly connected to the rotating shaft of the collection cylinder. A support base is installed on the outer surface of the traction frame below the swing rod. An infrared sensor is installed on one side of the motor's output shaft to monitor the motor's actual speed, ensuring that the speed of the receiving cylinder always matches the speed of the traction device. A packing mechanism is fixedly installed at the end of the traction frame; The floating film receiving mechanism further includes: a film lifting shovel, which is slidably mounted on the lower end of the traction frame, and a rotating film shaking rod is mounted on the outer surface of the middle section of the film lifting shovel. A rotating film shaking disc is mounted on the outer surface of the traction frame above the film lifting shovel, and a film shaking sprocket is fixedly connected to the outer surface of one side of the film shaking disc. A connecting rod is connected between the outer surface of the film shaking disc and the outer surface of the film lifting shovel. A rotating linkage sprocket is mounted on the outer surface of one end of the swing rod on the side where the connecting rod is located, and a transmission sprocket is mounted on the outer surface of the other end of the swing rod on that side. The transmission sprocket is fixedly connected to the rotating shaft of the receiving cylinder. The floating film collection mechanism further includes: a double-headed drive wheel, which is rotatably mounted on the inner surface of the middle section of the traction frame, and a blowing fan is fixedly mounted on the outer surface of the middle section of the traction frame. One end of the impeller shaft of the blowing fan is fixedly connected to a first fan drive wheel, and one end of the film lifting shovel is fixedly mounted with a blowing rod, and one end of the blowing rod is fixedly mounted with an air guide connector. A cleaning fan is fixedly installed on the outer surface of the middle section of the traction frame, and a second fan drive wheel is fixedly connected to one end of the impeller shaft of the cleaning fan. A guide groove is fixedly provided on one side of the outer surface of the guide hopper. The air outlet of the cleaning fan is inclined downwards, and the cleaning fan is located on one side of the traction frame, with the air outlet of the cleaning fan facing the inner center of the guide groove.

[0006] Preferably, one end of the feed hopper is designed to be open, and the inner surface of the feed hopper is in contact with the outer surface of the screw rod.

[0007] By adopting the above technical solution, the opening design of the guide bin and the close fit installation of the screw rod can form a screw conveying channel, which prevents the crushed residual film from scattering to both sides during the conveying process. At the same time, the rotation of the screw rod pushes the residual film to move in a direction, avoiding the accumulation of materials in the crushing chamber, and significantly improving the conveying efficiency and continuity.

[0008] Preferably, the crushed blocks are evenly distributed on the outer surface of the crushing roller, and adjacent crushed blocks are staggered, and the crushed blocks have a C-shaped opening design.

[0009] Using the above technical solution, the C-shaped opening and staggered arrangement of the crushed blocks can not only effectively tear and crush the straw when rotating at high speed, but also use the curved structure to cut the air to generate a directional high-pressure airflow. This airflow can promptly blow away impurities adhering to the surface of the residual film, while assisting the lightweight residual film to quickly enter the feed hopper, thus taking into account both crushing and anti-clogging functions.

[0010] Preferably, the outer surface of the traction frame opposite the swing rod is provided with an arc-shaped groove, and the arc-shaped groove on the surface of the traction frame is concentric with the rotation axis of the swing rod. One end of the receiving tooth rod passes through the outer surface of the receiving cylinder, and the outer surface of the receiving cylinder is provided with a clearance groove. The support base is slidably connected to the traction frame, and a spring is connected between the support base and the traction frame. The upper end of the support base is semi-circular, and the outer surface of the upper end of the support base is in contact with the lower surface of the middle section of the swing rod.

[0011] Using the above technical solution, the swing rod achieves large-angle up-and-down floating through the arc-shaped slot, and with the spring buffer between the support base and the traction frame, it can adaptively adjust the height and angle of the take-up cylinder according to the film tension.

[0012] Preferably, one end of the film-lifting shovel is positioned downwards toward the crushing roller, the film-shaking sprocket is connected to the linkage sprocket via a transmission chain, and the linkage sprocket is connected to the transmission sprocket via a transmission chain.

[0013] By adopting the above technical solution, the rotational power of the receiving cylinder is synchronously transmitted to the film-lifting shovel's shaking mechanism through the chain transmission of the shaking film sprocket, linkage sprocket, and transmission sprocket. The synchronous operation of picking up and shaking off soil can be achieved without the need for an additional power source. The structure is compact and the transmission is stable, ensuring that the residual film completes the initial separation of soil and impurities before being collected, reducing the pressure of subsequent impurity removal.

[0014] Preferably, the connecting rod is rotatably connected to the film shaking disc, and the end of the connecting rod connected to the film shaking disc is eccentrically set to the film shaking disc. Furthermore, the connecting rod is a two-section rotatably connected, and the connecting rod is rotatably connected to the film lifting shovel.

[0015] Using the above technical solution, the eccentrically set connecting rod converts the circular motion into the up-and-down reciprocating linear motion of the film lifting shovel when the shaking disc rotates. Combined with the flexible transmission characteristics of the two-stage rotating connection, it can soften the impact vibration and avoid damage to parts caused by rigid transmission. At the same time, the high-frequency shaking can effectively screen out large particles of soil and stones, improving the cleanliness of the residual film.

[0016] Preferably, one end of the double-headed drive wheel is connected to the first fan drive wheel via a drive belt, and the other end of the double-headed drive wheel is connected to the second fan drive wheel via a drive belt. The air outlet of the blowing fan is connected to the air guide connector via a flexible hose. Holes are evenly provided on the outer surface of the blowing rod, and the holes on the surface of the blowing rod face upwards.

[0017] Using the above technical solution, the dual-head drive wheel enables one power source to simultaneously drive the blowing fan and the impurity removal fan, simplifying the transmission system while ensuring that the two fans rotate at the same speed. The blowing rod surface is opened with air jet holes facing the crushing roller, which can accurately apply the airflow to the residual film conveying path, so that the residual film is in a suspended state, avoiding adhesion to the film lifting shovel, and further improving the air classification and impurity removal effect.

[0018] Compared with the prior art, the beneficial effects of the present invention are: the suspended pneumatic deep film recovery machine: 1. By setting C-shaped openings and staggered crushing blocks on the crushing roller, while crushing straw at high speed, a directional high-pressure airflow can be generated by the special curved surface structure. This airflow not only helps to blow away impurities adhering to the residual film, but also helps to blow the crushed light impurities into the feed bin. Combined with the rotation of the screw, the efficient conveying of impurities in the crushing chamber is achieved, ensuring the continuity of operation. 2. The floating film-receiving mechanism, through the cooperation of the support base and the spring, allows the swing rod with the receiving cylinder installed to float up and down. Regardless of the tension of the film being wound, the floating film-receiving mechanism can ensure stable winding of the film by rotation. At the same time, unlike the defects of traditional mechanical single power distribution, which results in the rotation speed being limited by the travel speed, the receiving cylinder of this application is directly driven by an independent motor. This design allows the rotation speed of the receiving cylinder to be independently optimized and adjusted according to the residual film amount and working conditions, unaffected by fluctuations in the tractor's travel speed, ensuring the stability of the picking torque and avoiding stalling or damage to the transmission system caused by sudden changes in resistance. 3. The receiving toothed rod rotates inside the receiving cylinder. When the toothed rod rotates to the bottom of the receiving cylinder, it extends to collect the material. When it rotates to the highest point, the toothed rod automatically flips and retracts, using centrifugal force to throw the residual film into the packaging mechanism behind. This dynamic unloading method of "scooping-lifting-throwing" effectively avoids the entanglement and accumulation of residual film on the receiving cylinder, and realizes smooth material transfer. 4. After the membrane lifting shovel is inserted into the soil, it shakes up and down repeatedly under the drive of the connecting rod. Utilizing the principle of vibrating screening, large particles of soil and gravel mixed in with the residual membrane are dislodged in advance during the transportation process. At the same time, the impurity removal fan, in conjunction with the guide channel, blows away the residual debris on the membrane. Furthermore, air is blown from bottom to top by the blowing rod, causing the residual membrane to be lifted into a suspended state, further promoting the separation of the residual membrane from impurities. Through the above multiple actions, the impurity content of the recycled residual membrane is greatly reduced, and the purity and reuse value of the recycled material are improved. 5. Because the blowing rod below the film lifting shovel sprays air upwards, the residual film does not directly contact the film lifting shovel. Instead, it is blown towards the receiving cylinder by floating, thus maximizing the integrity of the residual film. Attached Figure Description

After the tractor power is reduced by the reducer 3 at the end of the traction frame 1, it drives the first drive shaft 4 to rotate. The first drive shaft 4 drives the crushing drive wheel 9 to rotate through the transmission belt, which in turn drives the crushing roller 10 to rotate at high speed. The crushed blocks 11 on the surface of the crushing roller 10 have C-shaped openings and are staggered. When rotating at high speed, the C-shaped curved surface will cut straw and other impurities, and at the same time generate directional high-pressure airflow. On the one hand, it blows away the impurities adhering to the residual film, and on the other hand, it blows the crushed light impurities into the feed bin 5. At the same time, the first drive shaft 4 synchronously drives the guide drive wheel 6 to rotate, which in turn drives the screw rod 7 inside the guide bin 5 to rotate. The screw rod 7 fits against the inner wall of the guide bin 5, pushing the blown impurities axially to the opening of the guide bin 5.

The upper end of the support seat 17 is semi-circular, and the outer surface of the upper end of the support seat 17 is in contact with the lower surface of the middle section of the swing rod 12. The floating film receiving mechanism also includes: a film lifting shovel 18, which is slidably installed at the lower end of the traction frame 1, and a rotating film shaking rod 19 is installed on the outer surface of the middle section of the film lifting shovel 18. A rotating film shaking disc 21 is installed on the outer surface of the traction frame 1 above the film lifting shovel 18, and a film shaking sprocket 20 is fixedly connected to the outer surface of the film shaking disc 21 on one side. A connecting rod 22 is connected between the outer surface of the film shaking disc 21 and the outer surface of the film lifting shovel 18. A rotating linkage sprocket 23 is installed on the outer surface of one end of the swing rod 12 on the side where the connecting rod 22 is located, and a transmission sprocket 24 is installed on the outer surface of the other end of the swing rod 12 on the same side. The transmission sprocket 24 is fixedly connected to the rotating shaft of the receiving cylinder 13. The floating film collection mechanism also includes: a double-headed drive wheel 25, which is rotatably mounted on the inner surface of the middle section of the traction frame 1, and a blowing fan 26 is fixedly mounted on the outer surface of the middle section of the traction frame 1. One end of the impeller shaft of the blowing fan 26 is fixedly connected to a first fan drive wheel 27, and a blowing rod 28 is fixedly mounted on one end of the film lifting shovel 18. An air guide connector 29 is fixedly mounted on one end of the blowing rod 28. A cleaning fan 30 is fixedly installed on the outer surface of the middle section of the traction frame 1, and a second fan drive wheel 31 is fixedly connected to one end of the impeller shaft of the cleaning fan 30. A guide groove 32 is fixedly provided on the outer surface of one side of the guide hopper 5. The air outlet of the cleaning fan 30 is inclined downward, and the cleaning fan 30 is located on one side of the traction frame 1. The air outlet of the cleaning fan 30 is set towards the inner center of the guide groove 32. One end of the film-lifting shovel 18 is set downward toward the crushing roller 10, the film-shaking sprocket 20 is connected to the linkage sprocket 23 through the transmission chain, and the linkage sprocket 23 is connected to the transmission sprocket 24 through the transmission chain. The connecting rod 22 is rotatably connected to the film shaking disk 21, and the end of the connecting rod 22 connected to the film shaking disk 21 is eccentrically set to the film shaking disk 21.

One end of the double-headed drive wheel 25 is connected to the first fan drive wheel 27 via a drive belt, and the other end of the double-headed drive wheel 25 is connected to the second fan drive wheel 31 via a drive belt. The air outlet of the blowing fan 26 is connected to the air guide connector 29 via a hose. Holes are evenly opened on the outer surface of the blowing rod 28, and the holes on the surface of the blowing rod 28 are set facing upward. During operation, the independent motor 15 drives the collecting cylinder 13 to rotate. An infrared sensor is installed on one side of the output shaft of the motor 15 to monitor the actual speed of the motor 15, so as to ensure that the speed of the collecting cylinder 13 always matches the speed of the traction device. The collecting toothed rod 14 inside the collecting cylinder 13 rotates with the cylinder body: when the toothed rod rotates to the bottom of the collecting cylinder 13, it extends to collect the residual film on the ground surface, and automatically retracts when it rotates to the top. The residual film is thrown into the packaging mechanism 16 by centrifugal force. The packaging mechanism 16 conveys the residual film backward through the horizontal conveyor belt, while the inclined conveyor belt will package the residual film into a roll to avoid the residual film from tangling. Impurities separated from the mulch film can also be conveyed backward through the horizontal conveyor belt to avoid adhering to the residual film again. At the same time, the support seat 17 at the bottom of the swing rod 12 is connected to the traction frame 1 through the spring. When the tension of the mulch film changes, the support seat 17 can slide along the traction frame 1, driving the swing rod 12 to float up and down around the rotating shaft, ensuring that the collecting cylinder 13 always maintains the best picking angle and ensuring continuous collection of mulch film. During the collection process, the film-lifting shovel 18 is inserted 20-30 cm below the ground surface. The rotating shaft of the receiving cylinder 13 drives the transmission sprocket 24 to rotate. Through the transmission of the linkage sprocket 23 and the film-shaking sprocket 20, the film-shaking disc 21 is driven to rotate. The film-shaking disc 21 drives the film-lifting shovel 18 and the film-shaking rod 19 to shake up and down repeatedly through the eccentrically connected connecting rod 22, so that large particles of soil and gravel mixed in with the residual film are removed in advance. At the same time, the double-headed transmission wheel 25 drives the first fan transmission wheel 27 and the second fan transmission wheel 3. 1. Simultaneously drive the blowing fan 26 and the impurity removal fan 30 to operate. The airflow generated by the blowing fan 26 enters the blowing rod 28 through the air guide joint 29 and sprays air upward from the hole facing the crushing roller 10, lifting the residual film into a suspended state. At this time, the residual film can be better directly hung on the receiving cylinder 13 to avoid further damage caused by pulling. The impurity removal fan 30 tilts downward and blows air towards the center of the inner side of the guide groove 32 to blow away the residual debris on the surface of the residual film, and finally achieves the recovery of residual film with low impurity content.
